Title: Methods and apparatus for manufacturing a glass ribbon

Description:
This application claims the benefit of priority under 35 U.S.C. § 119 of U.S. Provisional Application Ser. No. 62/718,664, filed on Aug. 14, 2018, the content of which is relied upon and incorporated herein by reference in its entirety. 
    
    
     FIELD 
     The present disclosure relates generally to methods and apparatus for gripping a glass ribbon and, more particularly, to methods of gripping a glass ribbon with a glass ribbon gripping device comprising one or more jaw clamps. 
     BACKGROUND 
     It is known to grip a glass ribbon with a vacuum cup during a fusion forming process of the glass ribbon. Slippage between the vacuum cup and the glass ribbon is possible due to the heat of the glass ribbon. In addition, this heat may lead to a shortened lifespan of the vacuum cup, thus increasing costs due to repair or replacement of the vacuum cup. 
     SUMMARY 
     The following presents a simplified summary of the disclosure to provide a basic understanding of some embodiments described in the detailed description. 
     In accordance with some embodiments, a glass manufacturing apparatus can comprise a glass ribbon gripping device comprising a first column of jaw clamps spaced from one another along a first clamp path extending in a glass ribbon travel direction of the glass manufacturing apparatus. The glass ribbon gripping device can comprise a second column of jaw clamps spaced from one another along a second clamp path extending in the glass ribbon travel direction of the glass manufacturing apparatus. The first column of jaw clamps and the second column of jaw clamps can be spaced apart in a lateral direction perpendicular to the glass ribbon travel direction. 
     In one embodiment, the glass manufacturing apparatus can further comprise a support surface positioned below at least one of the first column of jaw clamps and the second column of jaw clamps. The support surface can extend at least partially across a travel path of the glass ribbon. 
     In another embodiment, at least one jaw clamp of the first column of jaw clamps can be laterally adjustable in the lateral direction relative to at least one jaw clamp of the second column of jaw clamps. 
     In another embodiment, at least one jaw clamp of the first column of jaw clamps can be vertically adjustable in the glass ribbon travel direction relative to at least one jaw clamp of the second column of jaw clamps. 
     In another embodiment, at least one jaw clamp of the second column of jaw clamps can be vertically adjustable in the glass ribbon travel direction relative to at least one jaw clamp of the first column of jaw clamps. 
     In another embodiment, a first jaw clamp of the first column of jaw clamps and a first jaw clamp of the second column of jaw clamps can form a first elevational pair of jaw clamps positioned at a first elevation. A second jaw clamp of the first column of jaw clamps and a second jaw clamp of the second column of jaw clamps can form a second elevational pair of jaw clamps positioned at a second elevation. 
     In another embodiment, a first lateral spacing between the jaw clamps of the first elevational pair of jaw clamps can be adjustable in the lateral direction. 
     In another embodiment, the first lateral spacing between the jaw clamps of the first elevational pair of jaw clamps can be adjustable in the lateral direction independent of a second lateral spacing between the jaw clamps of the second elevational pair of jaw clamps. 
     In another embodiment, a second lateral spacing between the jaw clamps of the second elevational pair of jaw clamps can be adjustable in the lateral direction. 
     In another embodiment, the second lateral spacing between the jaw clamps of the second elevational pair of jaw clamps can be adjustable in the lateral direction independent of a first lateral spacing between the jaw clamps of the first elevational pair of jaw clamps. 
     In another embodiment, a method can be provided for manufacturing a glass ribbon with the glass manufacturing apparatus. Methods can comprise moving the glass ribbon along the glass ribbon travel direction. The glass ribbon can comprise a first major surface and a second major surface. Methods can further comprise clamping a first lateral edge of the glass ribbon with the first column of jaw clamps by engaging the first major surface and the second major surface with each jaw clamp of the first column of jaw clamps. Methods can further comprise clamping a second lateral edge of the glass ribbon with the second column of jaw clamps by engaging the first major surface and the second major surface with each jaw clamp of the second column of jaw clamps. 
     In another embodiment, methods can further comprise separating the glass ribbon from another portion of the glass ribbon and catching the separated glass ribbon with the clamping of the first lateral edge and the second lateral edge of the glass ribbon. 
     In another embodiment, methods can further comprise engaging a lower edge of the glass ribbon prior to clamping the first lateral edge and the second lateral edge of the glass ribbon. 
     In another embodiment, methods can further comprise adjusting a first lateral spacing between a first jaw clamp of the first column of jaw clamps and a first jaw clamp of the second column of jaw clamps to adjust a first lateral tension of the glass ribbon at a first elevation. 
     In another embodiment, the adjusted first lateral tension of the glass ribbon at the first elevation can be different than a second lateral tension of the glass ribbon at the second elevation of the glass ribbon. 
     In another embodiment, methods can further comprise adjusting a second lateral spacing between a second jaw clamp of the first column of jaw clamps and a second jaw clamp of the second column of jaw clamps to adjust a second lateral tension at a second elevation of the glass ribbon. 
     In another embodiment, adjusting the second lateral tension can be conducted independent of adjusting the first lateral tension. 
     In another embodiment, the adjusted first lateral tension can be different than the adjusted second lateral tension. 
     In another embodiment, the first column of jaw clamps, the second column of jaw clamps, and the glass ribbon can move together at the same velocity along the glass ribbon travel direction prior to clamping the first lateral edge of the glass ribbon with the first column of jaw clamps and prior to clamping a second lateral edge of the glass ribbon with the second column of jaw clamps. 
     In another embodiment, the first column of jaw clamps, the second column of jaw clamps, and the glass ribbon can move together at the same velocity along the glass ribbon travel direction after clamping the first lateral edge of the glass ribbon with the first column of jaw clamps and after clamping a second lateral edge of the glass ribbon with the second column of jaw clamps.

     DETAILED DESCRIPTION 
     Embodiments will now be described more fully hereinafter with reference to the accompanying drawings in which example embodiments are shown. Whenever possible, the same reference numerals are used throughout the drawings to refer to the same or like parts. However, this disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. 
     It is to be understood that specific embodiments disclosed herein are intended to be exemplary and therefore non-limiting. For purposes of the disclosure, although not required, the glass manufacturing apparatus can optionally comprise a glass forming apparatus that forms a glass sheet and/or glass ribbon from a quantity of molten material. For example, the glass manufacturing apparatus can optionally comprise a glass forming apparatus such as a slot draw apparatus, float bath apparatus, down-draw apparatus, up-draw apparatus, press-rolling apparatus or other glass forming apparatus. In the embodiment illustrated in  FIG. 1  discussed below, the glass manufacturing apparatus can comprise a glass forming apparatus comprising a fusion down-draw apparatus although other glass forming apparatus maybe provided in further embodiments. 
     Furthermore, for purposes of the disclosure, although not required, the glass manufacturing apparatus can comprise a storage device for storing a previous-formed glass ribbon and/or glass sheet. For example, although not shown, the glass manufacturing apparatus may optionally comprise a storage spool comprising a length of the glass ribbon wound on the storage spool. In some embodiments, the glass manufacturing apparatus may unwind a portion of the glass ribbon from the storage spool during a method of manufacturing the glass ribbon. 
     As schematically illustrated in  FIG. 1 , in some embodiments, an exemplary glass manufacturing apparatus  100  can comprise a glass forming apparatus  101  comprising a forming vessel  140  designed to produce a glass ribbon  104  from a quantity of molten material  121 . In some embodiments, the glass ribbon  104  can comprise a central portion  152  disposed between opposite, relatively thick edge beads formed along a first lateral edge  153  and a second lateral edge  155  of the glass ribbon  104 . Additionally, in some embodiments, a portion of the glass ribbon  104  can be separated along a separation path  151  by a glass separator  149  (e.g., scribe, score wheel, diamond tip, laser, etc.). In some embodiments, before or after separation of the portion of the glass ribbon  104  with the glass separator  149 , the relatively thick edge beads formed along the first lateral edge  153  and the second lateral edge  155  can be removed to provide the central portion  152  as a high-quality glass ribbon  104  having a uniform thickness. 
     In some embodiments, the glass manufacturing apparatus  100  can comprise a melting vessel  105  oriented to receive batch material  107  from a storage bin  109 . The batch material  107  can be introduced by a batch delivery device  111  powered by a motor  113 . In some embodiments, an optional controller  115  can be operated to activate the motor  113  to introduce a desired amount of batch material  107  into the melting vessel  105 , as indicated by arrow  117 . The melting vessel  105  can heat the batch material  107  to provide molten material  121 . In some embodiments, a glass melt probe  119  can be employed to measure a level of molten material  121  within a standpipe  123  and communicate the measured information to the controller  115  by way of a communication line  125 . 
     Additionally, in some embodiments, the glass manufacturing apparatus  100  can comprise a first conditioning station comprising a fining vessel  127  located downstream from the melting vessel  105  and coupled to the melting vessel  105  by way of a first connecting conduit  129 . In some embodiments, molten material  121  can be gravity fed from the melting vessel  105  to the fining vessel  127  by way of the first connecting conduit  129 . For example, in some embodiments, gravity can drive the molten material  121  through an interior pathway of the first connecting conduit  129  from the melting vessel  105  to the fining vessel  127 . Additionally, in some embodiments, bubbles can be removed from the molten material  121  within the fining vessel  127  by various techniques. 
     In some embodiments, the glass manufacturing apparatus  100  can further comprise a second conditioning station comprising a mixing chamber  131  that can be located downstream from the fining vessel  127 . The mixing chamber  131  can be employed to provide a homogenous composition of molten material  121 , thereby reducing or eliminating inhomogeneity that may otherwise exist within the molten material  121  exiting the fining vessel  127 . As shown, the fining vessel  127  can be coupled to the mixing chamber  131  by way of a second connecting conduit  135 . In some embodiments, molten material  121  can be gravity fed from the fining vessel  127  to the mixing chamber  131  by way of the second connecting conduit  135 . For example, in some embodiments, gravity can drive the molten material  121  through an interior pathway of the second connecting conduit  135  from the fining vessel  127  to the mixing chamber  131 . 
     Additionally, in some embodiments, the glass manufacturing apparatus  100  can comprise a third conditioning station comprising a delivery vessel  133  that can be located downstream from the mixing chamber  131 . In some embodiments, the delivery vessel  133  can condition the molten material  121  to be fed into an inlet conduit  141 . For example, the delivery vessel  133  can function as an accumulator and/or flow controller to adjust and provide a consistent flow of molten material  121  to the inlet conduit  141 . As shown, the mixing chamber  131  can be coupled to the delivery vessel  133  by way of a third connecting conduit  137 . In some embodiments, molten material  121  can be gravity fed from the mixing chamber  131  to the delivery vessel  133  by way of the third connecting conduit  137 . For example, in some embodiments, gravity can drive the molten material  121  through an interior pathway of the third connecting conduit  137  from the mixing chamber  131  to the delivery vessel  133 . As further illustrated, in some embodiments, a delivery pipe  139  (e.g., downcomer) can be positioned to deliver molten material  121  to the inlet conduit  141  of the forming vessel  140 . 
     Various embodiments of forming vessels can be provided in accordance with features of the disclosure comprising a forming vessel with a wedge for fusion drawing the glass ribbon, a forming vessel with a slot to slot draw the glass ribbon, or a forming vessel provided with press rolls to press roll the glass ribbon from the forming vessel. By way of illustration, the forming vessel  140  shown and disclosed below can be provided to fusion draw molten material  121  off a root  145  of a forming wedge  209  to produce the glass ribbon  104 . For example, in some embodiments, the molten material  121  can be delivered from the inlet conduit  141  to the forming vessel  140 . The molten material  121  can then be formed into the glass ribbon  104  based at least in part on the structure of the forming vessel  140 . For example, as shown, the molten material  121  can be drawn off the bottom edge (e.g., root  145 ) of the forming vessel  140  along a draw path extending in a glass ribbon travel direction  154  of the glass manufacturing apparatus  100 . In some embodiments, edge directors  163   a ,  163   b  can direct the molten material  121  off the forming vessel  140  and define, at least in part, a width “W” of the glass ribbon  104 . In some embodiments, the width “W” of the glass ribbon  104  can extend between the first lateral edge  153  of the glass ribbon  104  and the second lateral edge  155  of the glass ribbon  104 . 
     In some embodiments, the width “W” of the glass ribbon  104  can be greater than or equal to about 20 mm, such as greater than or equal to about 50 mm, such as greater than or equal to about 100 mm, such as greater than or equal to about 500 mm, such as greater than or equal to about 1000 mm, such as greater than or equal to about 2000 mm, such as greater than or equal to about 3000 mm, such as greater than or equal to about 4000 mm, although other widths less than or greater than the widths mentioned above can be provided in further embodiments. For example, in some embodiments, the width “W” of the glass ribbon  104  can be from about 20 mm to about 4000 mm, such as from about 50 mm to about 4000 mm, such as from about 100 mm to about 4000 mm, such as from about 500 mm to about 4000 mm, such as from about 1000 mm to about 4000 mm, such as from about 2000 mm to about 4000 mm, such as from about 3000 mm to about 4000 mm, such as from about 20 mm to about 3000 mm, such as from about 50 mm to about 3000 mm, such as from about 100 mm to about 3000 mm, such as from about 500 mm to about 3000 mm, such as from about 1000 mm to about 3000 mm, such as from about 2000 mm to about 3000 mm, such as from about 2000 mm to about 2500 mm, and all ranges and subranges therebetween. 
       FIG. 2  shows a cross-sectional perspective view of the glass manufacturing apparatus  100  along line  2 - 2  of  FIG. 1 . In some embodiments, the forming vessel  140  can comprise a trough  201  oriented to receive the molten material  121  from the inlet conduit  141 . For illustrative purposes, cross-hatching of the molten material  121  is removed from  FIG. 2  for clarity. The forming vessel  140  can further comprise the forming wedge  209  comprising a pair of downwardly inclined converging surface portions  207   a ,  207   b  extending between opposed ends  210   a ,  210   b  (See  FIG. 1 ) of the forming wedge  209 . The pair of downwardly inclined converging surface portions  207   a ,  207   b  of the forming wedge  209  can converge along the glass ribbon travel direction  154  to intersect along a bottom edge of the forming wedge  209  to define the root  145  of the forming vessel  140 . A draw plane  213  of the glass manufacturing apparatus  100  can extend through the root  145  along the glass ribbon travel direction  154 . In some embodiments, the glass ribbon  104  can be drawn in the glass ribbon travel direction  154  along the draw plane  213 . As shown, the draw plane  213  can bisect the forming wedge  209  through the root  145  although, in some embodiments, the draw plane  213  can extend at other orientations relative to the root  145 . 
     Additionally, in some embodiments, the molten material  121  can flow in a direction  156  into the trough  201  of the forming vessel  140 . The molten material  121  can then overflow from the trough  201  by simultaneously flowing over corresponding weirs  203   a ,  203   b  and downward over the outer surfaces  205   a ,  205   b  of the corresponding weirs  203   a ,  203   b . Respective streams of molten material  121  can then flow along the downwardly inclined converging surface portions  207   a ,  207   b  of the forming wedge  209  to be drawn off the root  145  of the forming vessel  140 , where the flows converge and fuse into the glass ribbon  104 . The glass ribbon  104  can then be fusion drawn off the root  145  in the draw plane  213  along the glass ribbon travel direction  154 . In some embodiments, the glass separator  149  (see  FIG. 1 ) can then subsequently separate a portion of the glass ribbon  104  along the separation path  151 . For example, as shown in  FIG. 1 , a portion of a glass ribbon  104  in the form of a glass sheet can be separated from the glass ribbon  104  along the separation path  151 . As illustrated, in some embodiments, the separation path  151  can extend along the width “W” of the glass ribbon  104  between the first lateral edge  153  and the second lateral edge  155 . Additionally, in some embodiments, the separation path  151  can extend perpendicular to the glass ribbon travel direction  154  of the glass ribbon  104 . Moreover, in some embodiments, the glass ribbon travel direction  154  can define a direction along which the glass ribbon  104  can be fusion drawn from the forming vessel  140 . In some embodiments, the glass ribbon  104  can include a speed as it traverses along the glass ribbon travel direction  154  of ≥50 mm/s, ≥100 mm/s, or ≥500 mm/s, for example, from about 50 mm/s to about 500 mm/s, such as from about 100 mm/s to about 500 mm/s, and all ranges and subranges therebetween. 
     As shown in  FIG. 2 , the glass ribbon  104  can be drawn from the root  145  with a first major surface  215   a  of the glass ribbon  104  and a second major surface  215   b  of the glass ribbon  104  facing opposite directions and defining a thickness “T” (e.g., average thickness) of the glass ribbon  104 . In some embodiments, the thickness “T’ of the glass ribbon  104  can be less than or equal to about 2 millimeters (mm), less than or equal to about 1 millimeter, less than or equal to about 0.5 millimeters, for example, less than or equal to about 300 micrometers (μm), less than or equal to about 200 micrometers, or less than or equal to about 100 micrometers, although other thicknesses may be provided in further embodiments. For example, in some embodiments, the thickness “T’ of the glass ribbon  104  can be from about 50 μm to about 750 μm, from about 100 μm to about 700 μm, from about 200 μm to about 600 μm, from about 300 μm to about 500 μm, from about 50 μm to about 500 μm, from about 50 μm to about 700 μm, from about 50 μm to about 600 μm, from about 50 μm to about 500 μm, from about 50 μm to about 400 μm, from about 50 μm to about 300 μm, from about 50 μm to about 200 μm, from about 50 μm to about 100 μm, including all ranges and subranges of thicknesses therebetween. In addition, the glass ribbon  104  can comprise a variety of compositions comprising, but not limited to, soda-lime glass, borosilicate glass, alumino-borosilicate glass, alkali-containing glass, or alkali-free glass. 
     Referring to  FIG. 3 , it will be appreciated that the glass ribbon  104  may be provided by one or more types of sources  300 .  FIG. 3  illustrates two example sources  300  of the glass ribbon  104 , though other sources may be provided in further embodiments. For instance, in some embodiments, one source  300  may comprise the forming vessel  140  illustrated and described with respect to  FIGS. 1 and 2 . The forming vessel  140  may comprise the forming wedge  209  comprising the downwardly inclined converging surface portions  207   a ,  207   b  and the root  145 . 
     In another embodiment, another source  300  of the glass ribbon  104  may comprise a coiled spool  301  of ribbon (e.g., glass ribbon). For example, the glass ribbon  104  may be wound into the coiled spool  301  after being drawn into a glass ribbon from a quantity of the molten material  121 , for example, with the forming vessel  140 . The glass ribbon of the coiled spool  301  may or may not have the edge beads formed along the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 . However, if a greater thickness of edge beads is present, the edge beads may increase the bend radius that avoids cracking or breaking the glass ribbon  104 . As such, if coiled, the glass ribbon  104  may be coiled with a relatively large bend radius such that a given length of the glass ribbon may use the coiled spool  301  with a relatively large diameter “Dl.” In contrast, if the edge beads are removed, the glass ribbon  104  may be coiled with a relatively small bend radius. If the source  300  comprises the coiled spool  301 , the glass ribbon  104  may be uncoiled from the coiled spool  301  to traverse in the glass ribbon travel direction  154 . As shown, in some embodiments, the glass ribbon travel direction  154  may comprise the direction of gravity although the glass ribbon travel direction  154  can comprise a lateral draw direction traveling at an angle (e.g., perpendicular) to gravity depending on the source of the glass ribbon  104  and/or configuration of the glass manufacturing apparatus  100 . 
     Referring to  FIG. 4 , the glass manufacturing apparatus  100  may comprise a glass ribbon gripping device  400 . The glass ribbon gripping device  400  may be disposed downstream from the source  300  (e.g., the forming vessel  140  or the coiled spool  301 ). In some embodiments, the glass ribbon gripping device  400  may assist in handling and/or directing movement of the glass ribbon  104 . For example, the glass ribbon gripping device  400  can handle and/or direct movement of the glass ribbon  104  prior to, during, and/or after the separation of the portion of the glass ribbon  104  by the glass separator  149 . 
     The glass ribbon gripping device  400  can comprise a frame  401  that can comprise one or more frame arms. In some embodiments, the frame  401  can comprise one or more lateral frame arms  403  that can extend in a direction that may be perpendicular to the glass ribbon travel direction  154  although the frame arms can extend in non-perpendicular directions in further embodiments. While the embodiment of  FIG. 4  is illustrated as comprising two lateral frame arms  403 , it will be appreciated that the glass ribbon gripping device  400  may comprise any number of lateral frame arms  403  extending perpendicular and/or at other angles relative to the glass ribbon travel direction  154 . 
     In some embodiments, the frame  401  can comprise one or more vertical frame arms, such as a first vertical frame arm  405  and a second vertical frame arm  407 . In some embodiments, the first vertical frame arm  405  and the second vertical frame arm  407  can extend parallel to one another although non-parallel configurations may be provided in further embodiments. As shown, in some embodiments, the first vertical frame arm  405  and the second vertical frame arm  407  can also extend in the glass ribbon travel direction  154 , although, in other embodiments, the first vertical frame arm  405  and the second vertical frame arm  407  can extend non-parallel to the glass ribbon travel direction  154 . In some embodiments, the first vertical frame arm  405  and the second vertical frame arm  407  may be attached to opposing ends of the lateral frame arms  403 . For example, a first end of the lateral frame arms  403  may be attached to the first vertical frame arm  405  while an opposing second end of the lateral frame arms  403  may be attached to the second vertical frame arm  407 . In some embodiments, the first vertical frame arm  405  and the second vertical frame arm  407  may be spaced apart from each other and maintained with a substantially fixed distance between the first vertical frame arm  405  and the second vertical frame arm  407 . In some embodiments, the frame  401  may comprise one or more additional angled frame arms that can be attached to one or more of the lateral frame arms  403 , the first vertical frame arms  405 , and/or the second vertical frame arm  407 . These angled frame arms may extend parallel to, perpendicular to, or at an angle other than parallel or perpendicular to the glass ribbon travel direction  154 . In some embodiments, the frame  401  may comprise a substantially rigid material, such as a metal material, that can be limited from experiencing inadvertent bending, flexing, etc. 
     The glass ribbon gripping device  400  may comprise one or more columns of jaw clamps. For example, the glass ribbon gripping device  400  may comprise a first column of jaw clamps  409  spaced from one another along a first clamp path  411  extending in the glass ribbon travel direction  154  of the glass manufacturing apparatus  100 . The glass ribbon gripping device  400  may comprise a second column of jaw clamps  415  spaced from one another along a second clamp path  417  extending in the glass ribbon travel direction  154  of the glass manufacturing apparatus  100 . In some embodiments, the first clamp path  411 , which may extend in a first clamp direction  413  of the glass ribbon travel direction  154 , may be substantially parallel to the second clamp path  417 , which may extend in a second clamp direction  419  of the glass ribbon travel direction  154 , such that the first column of jaw clamps  409  may be arranged substantially parallel to the second column of jaw clamps  415 . The first column of jaw clamps  409  may be attached to the first vertical frame arm  405  and the second column of jaw clamps  415  may be attached to the second vertical frame arm  407 . By being attached to the first vertical frame arm  405  and the second vertical frame arm  407 , the first column of jaw clamps  409  and the second column of jaw clamps  415  may be spaced apart in a lateral direction  421  that can be perpendicular to the glass ribbon travel direction  154 . 
     In some embodiments, the first clamp path  411  and the second clamp path  417  may or may not extend vertically in the direction of gravity. Rather, in some embodiments, the first clamp path  411  and the second clamp path  417  may be positioned to extend at an angle with respect to the direction of gravity, wherein a vector of the first clamp path  411  and the second clamp path  417  has a vertical component in the direction of gravity and a horizontal component in a direction perpendicular to the direction of gravity. In some embodiments, the glass ribbon travel direction  154  can extend in the direction of gravity or may likewise extend at an angle with respect to the direction of gravity. 
     In some embodiments, the first column of jaw claims  409  and the second column of jaw clamps  415  may each comprise two or more jaw clamps. For instance, in the illustrated embodiment, the first column of jaw clamps  409  may comprise a first jaw clamp  423 , a second jaw clamp  425 , and a third jaw clamp  427 . The first jaw clamp  423  may be located at a higher elevation that the second jaw clamp  425  and the third jaw claim  427  and in closer proximity to the source  300  than the second jaw clamp  425  and the third jaw clamp  427 . The second jaw clamp  425  may be disposed at an elevation between the elevation of the first jaw clamp  423  and an elevation of the third jaw clamp  427  along the first clamp path  411 . In some embodiments, a first spacing between the first jaw clamp  423  and the second jaw clamp  425  may be equal to a second spacing between the second jaw clamp  425  and the third jaw clamp  427 . However, as will be described herein, the first spacing and the second spacing may be adjustable and non-constant. For instance, in some embodiments, the first jaw clamp  423 , the second jaw clamp  425 , and/or the third jaw clamp  427  may be vertically adjustable relative to the frame  401 . In some embodiments, the first spacing between the first jaw clamp  423  and the second jaw clamp  425  may be greater than, equal to, or less than the second spacing between the second jaw clamp  425  and the third jaw clamp  427 . In some embodiments, the first jaw clamp  423 , the second jaw clamp  425 , and the third jaw clamp  427  may be aligned substantially coaxially along the first clamp path  411 . However, as will be described herein, the first jaw clamp  423 , the second jaw clamp  425 , and/or the third jaw clamp  427  may be laterally adjustable along the lateral direction  421  relative to the frame  401 . By adjusting one or more of the first jaw clamp  423 , the second jaw clamp  425 , and/or the third jaw clamp  427  laterally along the lateral direction  421 , the first jaw clamp  423 , the second jaw clamp  425 , and/or the third jaw clamp  427  may be arranged non-coaxially. 
     Still further, in the illustrated embodiment, the second column of jaw clamps  415  may comprise a first jaw clamp  429 , a second jaw clamp  431 , and a third jaw clamp  433 . The first jaw clamp  429  may be located at a higher elevation than the second jaw clamp  431  and the third jaw clamp  433  and in closer proximity to the source  300  than the second jaw clamp  431  and the third jaw clamp  433 . The second jaw clamp  431  may be disposed at an elevation between the elevation of first jaw clamp  429  and an elevation of the third jaw clamp  433  along the second clamp path  417 . In some embodiments, a first spacing between the first jaw clamp  429  and the second jaw clamp  431  may be equal to a second spacing between the second jaw clamp  431  and the third jaw clamp  433 . However, as will be described herein, the first spacing and the second spacing may be adjustable and non-constant. For instance, in some embodiments, the first jaw clamp  429 , the second jaw clamp  431 , and/or the third jaw clamp  433  be vertically adjustable relative to the frame  401 . In some embodiments, the first spacing between the first jaw clamp  429  and the second jaw clamp  431  may be greater than, equal to, or less than the second spacing between the second jaw clamp  431  and the third jaw clamp  433 . In some embodiments, the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  may be aligned substantially coaxially along the second clamp path  417 . However, as will be described herein, the first jaw clamp  429 , the second jaw clamp  431 , and/or the third jaw clamp  433  may be laterally adjustable along the lateral direction  421  relative to the frame  401 . By adjusting one or more of the first jaw clamp  429 , the second jaw clamp  431 , and/or the third jaw clamp  433  laterally along the lateral direction  421 , the first jaw clamp  429 , the second jaw clamp  431 , and/or the third jaw clamp  433  may be arranged non-coaxially. 
     In some embodiments, the first column of jaw clamps  409  and the second column of jaw clamps  415  may form one or more elevational pairs. For example, the first jaw clamp  423  of the first column of jaw clamps  409  and the first jaw clamp  429  of the second column of jaw clamps  415  may form a first elevational pair  439  of jaw clamps positioned at a first elevation  441 , wherein the first elevation  441  represents a distance from the first elevational pair  439  of jaw clamps to a bottom of the glass ribbon gripping device  400 . A first lateral spacing  442  may be defined between the first jaw clamp  423  of the first column of jaw clamps  409  and the first jaw clamp  429  of the second column of jaw clamps  415 . In some embodiments, the second jaw clamp  425  of the first column of jaw clamps  409  and the second jaw clamp  431  of the second column of jaw clamps  415  may form a second elevational pair  443  of jaw clamps positioned at a second elevation  445 , wherein the second elevation  445  represents a distance from the second elevational pair  443  of jaw clamps to a bottom of the glass ribbon gripping device  400 . A second lateral spacing  447  may be defined between the second jaw clamp  425  of the first column of jaw clamps  409  and the second jaw clamp  431  of the second column of jaw clamps  415 . In some embodiments, the third jaw clamp  427  of the first column of jaw clamps  409  and the third jaw clamp  433  of the second column of jaw clamps  415  may form a third elevational pair  449  of jaw clamps positioned at a third elevation  451 , wherein the third elevation  451  represents a distance from the third elevational pair  449  of jaw clamps to a bottom of the glass ribbon gripping device  400 . A third lateral spacing  453  may be defined between the third jaw clamp  427  of the first column of jaw clamps  409  and the third jaw clamp  433  of the second column of jaw clamps  415 . 
     In some embodiments the glass ribbon gripping device  400  may comprise at least one support surface positioned at an elevation at or below the lowest jaw clamp. For instance, in the illustrated embodiment, a support surface can be positioned below at least one of the first column of jaw clamps  409  and the second column of jaw clamps  415 , with the support surface extending across a travel path  465  of the glass ribbon  104 . The support surface may comprise, for example, a first support surface  461  and a second support surface  463  that may optionally be attached directly or indirectly to the frame  401 . For example, in the illustrated embodiment, the first support surface  461  may be attached to the first vertical frame arm  405  while the second support surface  463  may be attached to the second vertical frame arm  407 . As shown, in some embodiments, the third jaw clamp  427  may be attached to the first vertical frame arm  405  at an elevation between the elevation of the second jaw clamp  425  and the elevation of the first support surface  461 . Similarly, in some embodiments, the third jaw clamp  433  may be attached to the second vertical frame arm  407  at an elevation between the elevation of the second jaw clamp  431  and the elevation of the second support surface  463 . 
     The first support surface  461  and the second support surface  463  may extend at least partially across the travel path  465  of the glass ribbon  104 . In the illustrated example, the first support surface  461  and the second support surface  463  extend partially across the travel path  465  of the glass ribbon  104 , although one or more support surfaces may extend entirely across the travel path in further embodiments. Indeed, in the illustrated embodiment, the first support surface  461  and the second support surface  463  may be disposed towards lower corners of the frame  401  to provide support for the glass ribbon  104  at opposite edge portions of the glass ribbon  104 . Supporting at opposite edge portions can be beneficial in some embodiments since the edge portions may be removed at a subsequent time wherein only high-quality glass ribbon areas not physically contacted by the glass ribbon gripping device  400  remain after removal of the edge portions. In other embodiments, however, the support surface may extend completely across the travel path  465 , with one end of the support surface attached to the first vertical frame arm  405  and an opposing second end of the support surface attached to the second vertical frame arm  407 . In such an embodiment, the support surface may comprise a bar or other similar structure that may extend between the first vertical frame arm  405  and the second vertical frame arm  407 . Extending the support surface completely across the travel path may be beneficial to reduce stress concentrations on the lower edge of the glass ribbon. 
       FIG. 5  shows an end view of the glass ribbon gripping device  400  along line  5 - 5  of  FIG. 4 . The glass ribbon  104  is illustrated in  FIG. 5  in relation to the glass ribbon gripping device  400  and extending along the travel path  465 . While  FIG. 5  illustrates the first column of jaw clamps  409  (e.g., the first jaw clamp  423 , the second jaw clamp  425 , and the third jaw clamp  427 ), the first support surface  461 , and the first vertical frame arm  405 , it will be appreciated that the second column of jaw clamps  415  (e.g., the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433 ), the second vertical frame arm  407 , and the second support surface  463  may be substantially similar in structure and function. 
     Focusing upon the structure of the frame  401 , in some embodiments, the first major surface  215   a  of the glass ribbon  104  can face away from the frame  401  while the second major surface  215   b  of the glass ribbon  104  can face towards the frame  401 . The frame  401  may optionally comprise one or more protruding arms, such as a first protruding arm  501 , a second protruding arm  503 , and a third protruding arm  505 . The first protruding arm  501 , the second protruding arm  503 , and the third protruding arm  505 , if provided, can extend substantially perpendicular or at another angle relative to the first vertical frame arm  405 , and may be directly or indirectly attached to the first vertical frame arm  405 . In some embodiments, the first protruding arm  501 , the second protruding arm  503 , and the third protruding arm  505  can extend from the first vertical frame arm  405  towards the second major surface  215   b  of the glass ribbon  104 . The first jaw clamp  423  may be attached to the first protruding arm  501 , the second jaw clamp  425  may be attached to the second protruding arm  503 , and the third jaw clamp  427  may be attached to the third protruding arm  505 . 
     Focusing upon the structure of the first jaw clamp  423 , the first jaw clamp  423  can comprise a first pad  511  and a second pad  513 . The first pad  511  and the second pad  513  can be positioned on opposing sides of the glass ribbon  104 . For example, the first pad  511  can be positioned to face the first major surface  215   a  while the second pad  513  can be positioned to face the second major surface  215   b . Together, the first pad  511  and the second pad  513  can be brought together to clamp the glass ribbon  104 . 
     In some embodiments, the first pad  511  can be attached to an attachment arm  515 . The attachment arm  515  can be attached at one end to the first pad  511  and at an opposing end to a rotational cylinder  517 . The rotational cylinder  517  can impart movement to the attachment arm  515 . For example, the rotational cylinder  517  can cause the attachment arm  515  to rotate along a rotation path that can be parallel to the first major surface  215   a  of the glass ribbon  104  (e.g., into and out of the page in  FIG. 5 ). In addition, the rotational cylinder  517  can cause the attachment arm  515  to translate in a clamping direction that can be perpendicular to the first major surface  215   a  of the glass ribbon  104  (e.g., left and right in  FIG. 5 ). 
     In some embodiments, the attachment arm  515  may comprise a first arm portion  519  and a second arm portion  521 . The first arm portion  519  can extend substantially parallel to the glass ribbon  104  while the second arm portion  521  may extend substantially perpendicular to the glass ribbon  104 . In some embodiments, the second arm portion  521  may be attached to the rotational cylinder  517 , such as by being received within a recess of the rotational cylinder  517 , for example. The first arm portion  519  can be attached to the second arm portion  521  at an opposite end of the second arm portion  521  from the rotational cylinder  517 . The first pad  511  can be attached to the first arm portion  519  at an opposite end of the first arm portion  519  from the attachment of the first arm portion  519  and the second arm portion  521 . For example, the first pad  511  can be attached to an inner side of the first arm portion  519 , such that the first pad  511  faces the first major surface  215   a.    
     The rotational cylinder  517  can cause the attachment arm  515  and the first pad  511  to move between a clamped position and an unclamped position. For example, in the unclamped position that is illustrated in  FIG. 5 , the first pad  511  may not contact the glass ribbon  104  or may contact the glass ribbon  104  with a magnitude of force that may be low enough to not restrain movement of the glass ribbon  104  relative to the first pad  511  and the second pad  513 . In the clamped position (e.g., illustrated in  FIGS. 6 and 7 ), the first pad  511  and the second pad  513  may contact the glass ribbon  104  and apply a force, such as a compressive force, to the glass ribbon  104  that can be sufficient to restrain movement of the glass ribbon  104  relative to the first pad  511  and the second pad  513 . 
     While the foregoing description of the structure and function of a jaw clamp was made relative to the first jaw clamp  423 , it will be appreciated that the other jaw clamps (e.g., the second jaw clamp  425  and the third jaw clamp  427  of the first column of jaw clamps  409  and the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  of the second column of jaw clamps  415 ) may be substantially similar in structure and function to the first jaw clamp  423 . For example, the second jaw clamp  425  and the third jaw clamp  427  of the first column of jaw clamps  409 , and the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  of the second column of jaw clamps  415  may comprise the structures of the first jaw clamp  423 , such as the first pad  511 , the second pad  513 , the attachment arm  515  comprising the first arm portion  519  and the second arm portion  521 , the rotational cylinder  517 , etc. In these embodiments, the second jaw clamp  425  and the third jaw clamp  427  of the first column of jaw clamps  409 , and the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  of the second column of jaw clamps  415  can move in a similar fashion to the first jaw clamp  423  between the unclamped position (e.g., illustrated in  FIG. 5 ) and the clamped position (e.g., illustrated in  FIGS. 6 and 7 ). In these embodiments, the jaw clamps can function together to selectively allow for the glass ribbon  104  to move relative to the glass ribbon gripping device  400  when the jaw clamps are in the unclamped position, and to restrain movement of the glass ribbon  104  relative to the glass ribbon gripping device  400  when the jaw clamps are in the clamped position. 
     Focusing upon the structure of the first support surface  461 , the first support surface  461  can optionally be attached to an attachment arm  525 , which can be attached directly or indirectly to the frame  401 . In some embodiments, the attachment arm  525  may be attached to a lower end of the frame  401  and may extend in a direction that can be substantially perpendicular or at another direction relative to the frame  401  and the glass ribbon  104 . The glass ribbon gripping device  400  can comprise a rotational arm  527  that may be rotationally coupled to the attachment arm  525 . In some embodiments, the rotational arm  527  may be rotatably coupled to the attachment arm  525 . In some embodiments, the glass ribbon gripping device  400  may comprise one or more gears, motors, actuators, or the like coupled to the rotational arm  527  to impart rotation of the rotational arm  527  relative to the attachment arm  525 . 
     The first support surface  461  can be attached to a support arm  531  that can be attached to the rotational arm  527 . In some embodiments, the support arm  531  can extend outwardly from the rotational arm  527  in a direction that can be substantially perpendicular to the glass ribbon  104 . The support arm  531  may be fixedly attached to the rotational arm  527 , such that movement of the rotational arm  527  can likewise impart movement to the support arm  531 . In some embodiments, the first support surface  461  can be attached to a surface of the support arm  531 , with the first support surface  461  facing upwardly towards the source  300 . 
     Referring to  FIGS. 6 and 7 , movement of the first jaw clamp  423  between the unclamped position and the clamped position is illustrated. In some embodiments, the first jaw clamp  423  may initially be in the unclamped position of  FIG. 5 . The unclamped position is illustrated with dashed lines in  FIGS. 6 and 7  to represent a position of the attachment arm  515  and the first pad  511  when the attachment arm  515  is in the unclamped position. The rotational cylinder  517  can move the attachment arm  515  from the unclamped position to the clamped position. In some embodiments, the rotational cylinder  517  can impart rotational movement  701  to position the attachment arm  515  in an orientation for clamping and a clamping movement  703  to the attachment arm  515  to provide clamping of the glass ribbon between the pads  511 ,  513 . As the attachment arm  515  moves towards the clamped position, the first pad  511  can move towards the glass ribbon  104 . For example, in the unclamped position, the first pad  511  may be spaced apart from (e.g., not in contact with) the first major surface  215   a  of the glass ribbon  104 . In the clamped position, the first pad  511  may be moved into contact with the first major surface  215   a  of the glass ribbon  104  such that the first pad  511  can be substantially aligned with the second pad  513 . By being aligned, an axis may perpendicularly intersect the glass ribbon  104  while also intersecting the first pad  511  and the second pad  513 . 
     It will be appreciated that when the first jaw clamp  423  is in the clamped position, the first pad  511  and the second pad  513  may apply a compressive force to the glass ribbon  104 . This compressive force may be sufficient to hold the glass ribbon  104  by the first jaw clamp  423  and selectively impart movement to the glass ribbon  104 . In some embodiments, this compressive force may likewise be sufficient to hold the glass ribbon  104  in place relative to the first jaw clamp  423 , such that unintended movement of the glass ribbon  104  relative to the first jaw clamp  423  can be reduced. 
     While the foregoing description of the movement of a jaw clamp between the unclamped position and the clamped position was made relative to the first jaw clamp  423 , it will be appreciated that the other jaw clamps (e.g., the second jaw clamp  425  and the third jaw clamp  427  of the first column of jaw clamps  409  and the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  of the second column of jaw clamps  415 ) may function in a similar manner. For example, the second jaw clamp  425  and the third jaw clamp  427  of the first column of jaw clamps  409  and the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  of the second column of jaw clamps  415 ) may similarly move from the unclamped position (e.g., illustrated with dashed lines) to the clamped position to provide additional clamping of the glass ribbon  104  at a plurality of locations along the lateral edges  153 ,  155  of the glass ribbon  104 . The glass ribbon  104  may therefore be clamped at a plurality of locations by the first column of jaw clamps  409  and the second column of jaw clamps  415 . 
     The use of pads, such as the first pad  511  and the second pad  513 , may provide several benefits over other affixation structures, such as vacuum affixation, for example. In some embodiments, the first pad  511  and the second pad  513  may apply a compressive force to the first major surface  215   a  and the second major surface  215   b , respectively. Due to the first pad  511  and the second pad  513  not being vacuum affixed to the glass ribbon  104 , a gripping force may be increased as compared to a vacuum cup applying a vacuum affixation to one of the major surfaces  215   a ,  215   b . In some embodiments, the first pad  511  and the second pad  513  may be less prone to slippage as compared to the vacuum cup affixation due to heat from the glass ribbon  104 . In addition, the first pad  511  and the second pad  513  may experience extended life as compared to vacuum cup affixation, thus representing a cost savings. 
     Referring to  FIG. 7 , in some embodiments, the glass ribbon gripping device  400  can comprise one or more arms that facilitate movement of the first column of jaw clamps  409  and the second column of jaw clamps  415  relative to the frame  401 .  FIG. 7  illustrates an embodiment of the first jaw clamp  423  attached to the first protruding arm  501 . In some embodiments, the second pad  513  and the rotational cylinder  517  can be attached to one or more adjustment arms, with the adjustment arms attached to the first protruding arm  501 . For example, the adjustment arms may comprise a first adjustment arm  707  that can be attached to the first protruding arm  501  and a second adjustment arm  709  that may be attached to the first adjustment arm  707 . In some embodiments, the second pad  513  and the rotational cylinder  517  can be attached to the second adjustment arm  709 . 
     The first adjustment arm  707  can provide for lateral movement (e.g., into and out of the page in  FIG. 7 ). For example, the first adjustment arm  707  may be movable (e.g., by a motor or other actuator) into and out of the page relative to the first protruding arm  501 . Movement of the first adjustment arm  707  can cause lateral movement of the first jaw clamp  423  (e.g., into and out of the page in  FIG. 7 ). The lateral movement of the jaw clamps can be further described and illustrated herein with respect to  FIGS. 17 and 18 . The second adjustment arm  709  can provide for vertical movement (e.g., up and down in  FIG. 7 ). For example, the second adjustment arm  709  can be movable (e.g., by a motor or other actuator) up and down relative to the first adjustment arm  707 . Movement of the second adjustment arm  709  can cause vertical movement of the first jaw clamp  423 . The vertical movement of the jaw clamps can be further described and illustrated herein with respect to  FIG. 19 . 
     Referring to  FIG. 8 , rotational movement of the first support surface  461  along rotation direction  801  between an extended position and a retracted position is illustrated. In some embodiments, when the first support surface  461  is in the extended position (e.g., illustrated with dashed lines in  FIG. 8  to represent a position of the first support surface  461  in the extended position), the first support surface  461  may lie within a plane defined by the glass ribbon  104 , such that the plane defined by the glass ribbon  104  may intersect the first support surface  461  (e.g., also illustrated in  FIG. 5  in which the glass ribbon  104  intersects the first support surface  461 ). In some embodiments, a lower edge  803  of the glass ribbon  104  can engage the first support surface  461 , such as by contacting and/or resting upon the first support surface  461  as shown in  FIG. 11 . 
     The rotational arm  527  can rotate to cause the first support surface  461  to move along rotation direction  801  between the extended position (e.g., illustrated with dashed lines) and the retracted position (e.g., illustrated with solid lines). In some embodiments, movement of the first support surface  461  from the extended position towards the retracted position the rotational arm  527  can pivot about an axis in the rotation direction  801 . As the rotational arm  527  pivots, the support arm  531  and the first support surface  461  can likewise pivot. The rotational arm  527  can continue to pivot at least until the first support surface  461  no longer lies within the plane defined by the glass ribbon  104 . For example, in the retracted position, the glass ribbon  104  can be free to move downwardly along the glass ribbon travel direction  154  without the first support surface  461  engaging the lower edge  803  of the glass ribbon  104 . While the retracted position of the first support surface  461  is illustrated as being about 180° offset from the first support surface  461  in the extended position, it will be appreciated that such a degree of offset is not intended to be limiting. Rather, in some embodiments, the rotational arm  527  may rotate the first support surface  461  to a position in which the first support surface  461  does not interfere with the movement of the glass ribbon  104 , such as 90°, for example. 
     Referring to  FIGS. 9-20 , example embodiments of methods of manufacturing the glass ribbon  104  with the glass manufacturing apparatus  100  are illustrated. Referring to  FIG. 9 , methods of manufacturing the glass ribbon  104  can comprise moving the glass ribbon  104  along the glass ribbon travel direction  154 , wherein the glass ribbon  104  can comprise the first major surface  215   a  (e.g., facing out of the page) and the second major surface  215   b  (e.g., facing into the page). In some embodiments, as the glass ribbon  104  moves  901  along the glass ribbon travel direction  154 , methods of manufacturing the glass ribbon  104  comprise the first column of jaw clamps  409 , the second column of jaw clamps  415 , and the glass ribbon  104  moving  903 ,  905  together at the same velocity along the glass ribbon travel direction  154  prior to clamping the first lateral edge  153  of the glass ribbon  104  with the first column of jaw clamps  409  and prior to clamping the second lateral edge  155  of the glass ribbon  104  with the second column of jaw clamps  415 . It will be appreciated that the movement of the glass ribbon  104 , the first column of jaw clamps  409 , and the second column of jaw clamps  415  is illustrated schematically with arrows  901 ,  903 ,  905 . In some embodiments, the velocity of the first column of jaw clamps  409  and the second column of jaw clamps  415  may be the same as the velocity of the glass ribbon  104 . In such an embodiment, the glass ribbon gripping device  400  can track the movement of the glass ribbon  104  as the glass ribbon  104  moves  901  along the glass ribbon travel direction  154 . 
     In some embodiments, a portion of the glass ribbon  104  can be separated in any number of ways, such as with the glass separator  149  illustrated in  FIG. 10 . It will be appreciated that the glass separator  149  is illustrated schematically, as the glass separator  149  may represent several structures and/or operations that separate a portion of the glass ribbon  104  from the glass ribbon  104 . Embodiments of the glass separator  149  may comprise, for example, one or more of a scribe, a score wheel, a diamond tip, a laser, etc. 
     In the illustrated embodiment, during the separation of the portion of the glass ribbon  104 , the first column of jaw clamps  409  and the second column of jaw clamps  415  may be in the unclamped position. In the unclamped position, the first column of jaw clamps  409  and the second column of jaw clamps  415  may not grip and/or impart a force upon the glass ribbon  104 . For example, the glass ribbon  104  may not be restrained by the glass ribbon gripping device  400  and, thus, the glass ribbon  104  may move  901  independently and relative to the first column of jaw clamps  409  and the second column of jaw clamps  415  along the glass ribbon travel direction  154 . 
     Referring to  FIG. 11 , after the portion of the glass ribbon  104  has been separated by the glass separator  149 , the separated portion of the glass ribbon  104  may move  901  by free falling, due to the force of gravity, along the glass ribbon travel direction  154 . In some embodiments, methods of manufacturing the glass ribbon  104  can comprise engaging the lower edge  803  of the glass ribbon  104  prior to clamping the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 . In one embodiment, the first column of jaw clamps  409  and the second column of jaw clamps  415  may be held stationary and remain in the unclamped position. In another embodiment, the first column of jaw clamps  409  and the second column of jaw clamps  415  may move downwardly along the glass ribbon travel direction  154  at a velocity that may be less than the downward velocity at which the glass ribbon  104  moves  901  while free falling. In these embodiments, the lower edge  803  of the glass ribbon  104  can move into proximity with the first support surface  461  and the second support surface  463 , with a distance between the lower edge  803  and the first support surface  461  and the second support surface  463  decreasing. As the glass ribbon  104  moves downwardly, the lower edge  803  of the glass ribbon  104  can be engaged prior to clamping the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 . For example, the lower edge  803  of the glass ribbon  104  can be engaged by the first support surface  461  and the second support surface  463 . The lower edge  803  of the first lateral edge  153  can rest upon and/or be supported by the first support surface  461  while the lower edge  803  of the second lateral edge  155  can rest upon and/or be supported by the second support surface  463 . In some embodiments, engaging prior to clamping the first lateral edge  153  and the second lateral edge  155  can help align the glass ribbon  104  relative to the glass ribbon gripping device  400 . Indeed, in some embodiments, the engagement force may be less than the weight of the separated glass ribbon  104  and may be minimized or relatively low compared to the weight of the separated glass ribbon  104  to help prevent damage (e.g., by stress fracture) of the lower edge  803  of the glass ribbon  104 . At the same time, the engagement force may be large enough to allow any misalignment of the separated glass ribbon  104  due to the separation process to be realigned with respect to the glass ribbon gripping device  400  such that the subsequent clamping of the first lateral edge  153  and the second lateral edge  155  of the glass ribbon can occur at the proper locations of the lateral edges  153 ,  155 . Gripping at the proper locations of the lateral edges  153 ,  155  can help prevent surface damage to the pristine central portion  152  as well as minimize the amount of material to be removed, thereby maximizing the size of the pristine central portion  152 . 
     Referring to  FIG. 12 , methods of manufacturing the glass ribbon  104  can comprise clamping the first lateral edge  153  of the glass ribbon  104  with the first column of jaw clamps  409  by engaging the first major surface  215   a  and the second major surface  215   b  with each jaw clamp  423 ,  425 ,  427  of the first column of jaw clamps  409 . Methods of manufacturing the glass ribbon  104  may also comprise clamping the second lateral edge  155  of the glass ribbon  104  with the second column of jaw clamps  415  by engaging the first major surface  215   a  and the second major surface  215   b  with each jaw clamp  429 ,  431 ,  433  of the second column of jaw clamps  415 . For example, after the lower edge  803  of the glass ribbon  104  has been engaged by the first support surface  461  and the second support surface  463 , the glass ribbon  104  can be clamped by the jaw clamps. In some embodiments, the clamping of the first lateral edge  153  and the second lateral edge  155  can occur due to the first column of jaw clamps  409  and the second column of jaw clamps  415  moving from the unclamped position (e.g., illustrated in  FIG. 11 ) to the clamped position (e.g., illustrated in  FIG. 12 ). In the clamped position, the first column of jaw clamps  409  and the second column of jaw clamps  415  can grip the glass ribbon  104  (e.g., also illustrated in  FIGS. 6 and 7 ), such that the glass ribbon  104  may be limited from moving independently of the first column of jaw clamps  409  and the second column of jaw clamps  415 . With the first column of jaw clamps  409  and the second column of jaw clamps  415  in the clamped position, the glass ribbon gripping device  400  can move, guide, and/or direct the glass ribbon  104  to a desired location. 
     Throughout the disclosure, in the unclamped orientation as shown and discussed with respect to the dashed lines in  FIG. 6 , the attachment arm  515  and first pad  511  may be positioned away from and outside of the corresponding outer edge of the glass ribbon  104 . In such a position, the attachment arm  515  and first pad  511  will not interfere with the glass ribbon  104  in case there is a disturbance in the glass ribbon. For instance, the glass ribbon  104  may be able to travel past the attachment arm  515  and first pad  511  (in a direction out of the page shown in  FIG. 9 ) in instances where the glass ribbon is swaying back and forth relative to the root  145  of the forming wedge  209 . In some embodiments, the second pads  513  may engage the second major surface  215   b  of the glass ribbon first to help stabilize the glass ribbon prior to clamping. Alternatively, the glass ribbon  104  can be stabilized for proper positioning relative to the glass ribbon gripping device  400 . For instance, the swaying may stop or the amplitude of the swaying may be reduced to the point where the attachment arm  515  and first pad  511  will not interfere with the glass ribbon  104 . At that point, as shown in  FIG. 6-12 , the attachment arms  515  and first pads  511  may all be rotated about direction  701  to the position shown in solid lines in  FIGS. 6 and 7  and as further shown in  FIG. 12 . Then, jaw clamps may all undergo the clamping movement  703  described previously to pinch the corresponding first and second lateral edge  153 ,  155  with the jaw clamps. 
     Referring to  FIGS. 13 and 14 , further example embodiments of methods of manufacturing the glass ribbon  104  with the glass manufacturing apparatus  100  are illustrated. In these embodiments, methods of manufacturing the glass ribbon  104  can comprise separating the glass ribbon  104  and catching the separated glass ribbon  104  with the clamping of the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 . As with the previous embodiment illustrated in  FIGS. 9-12 , the first column of jaw clamps  409  and the second column of jaw clamps  415  may initially be in the unclamped position after the glass ribbon  104  has been separated by the glass separator  149 . 
     As illustrated in  FIG. 14 , after separation of the glass ribbon  104  by the glass separator  149 , methods can comprise catching the separated glass ribbon  104  with the clamping of the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 . In some embodiments, this clamping may comprise clamping the first lateral edge  153  of the glass ribbon  104  with the first column of jaw clamps  409  by engaging the first major surface  215   a  and the second major surface  215   b  with each jaw clamp (e.g., the first jaw clamp  423 , the second jaw clamp  425 , and the third jaw clamp  427 ) of the first column of jaw clamps  409 . This clamping may also comprise clamping the second lateral edge  155  of the glass ribbon  104  with the second column of jaw clamps  415  by engaging the first major surface  215   a  and the second major surface  215   b  with each jaw clamp (e.g., the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433 ) of the second column of jaw clamps  415 . 
     In some embodiments, the step of catching the glass ribbon  104  with the first column of jaw clamps  409  and the second column of jaw clamps  415  may occur prior to the lower edge  803  of the glass ribbon  104  engaging the first support surface  461  and the second support surface  463 . For example, as illustrated in  FIG. 14 , the lower edge  803  of the glass ribbon  104  may be spaced a distance apart from the first support surface  461  and the second support surface  463 . In some embodiments, the step of catching the glass ribbon  104  may occur during or immediately after the separation of the glass ribbon  104  such that the glass ribbon  104  may not free fall or may free fall only a short distance prior to being caught by the first column of jaw clamps  409  and the second column of jaw clamps  415 . In another embodiment, the step of catching the glass ribbon  104  may occur after the separation of the glass ribbon  104  such that the separated portion of glass ribbon  104  may fall a distance prior to being caught by the first column of jaw clamps  409  and the second column of jaw clamps  415  but before the lower edge  803  of the glass ribbon  104  engages the first support surface  461  and the second support surface  463 . 
     In the embodiment of  FIG. 14 , the first support surface  461  and the second support surface  463  may optionally be in the extended position or the retracted position. For example, due to the first column of jaw clamps  409  and the second column of jaw clamps  415  engaging and clamping the first lateral edge  153  and the second lateral edge  155  of the glass ribbon  104 , the glass ribbon  104  may be held by the first column of jaw clamps  409  and the second column of jaw clamps  415 , such that engagement of the lower edge  803  of the glass ribbon  104  by the first support surface  461  and the second support surface  463  may not be necessary. 
     Referring to  FIG. 15 , further embodiments of methods of manufacturing the glass ribbon  104  with the glass ribbon manufacturing apparatus  100  are illustrated. In this embodiment, the glass ribbon  104  can be clamped with the first column of jaw clamps  409  and the second column of jaw clamps  415  in the clamped position prior to the separation of the glass ribbon  104  from the another portion of the glass ribbon  104 . For example, the glass ribbon  104  can move along the glass ribbon travel direction  154 . The first column of jaw clamps  409  and the second column of jaw clamps  415  can move from the unclamped position to the clamped position (e.g., as illustrated) to clamp the first lateral edge  153  and the second lateral edge  155 . In some embodiments, methods of manufacturing the glass ribbon  104  comprise the first column of jaw clamps  409 , the second column of jaw clamps  415 , and the glass ribbon  104  moving together at the same velocity along the glass ribbon travel direction  154  after clamping the first lateral edge  153  of the glass ribbon  104  with the first column of jaw clamps  409  and the second lateral edge  155  of the glass ribbon  104  with the second column of jaw clamps  415  but before the separation of the glass ribbon  104  from the another portion of the glass ribbon  104  has occurred. 
     In some embodiments, the first column of jaw clamps  409  and the second column of jaw clamps  415  can move laterally as the glass ribbon  104  moves along the glass ribbon travel direction  154 . For example, the glass ribbon  104  may experience some degree of lateral, side-to-side movement as the glass ribbon  104  moves downwardly along the glass ribbon travel direction  154 . To accommodate for this lateral, side-to-side movement, the first column of jaw clamps  409  and the second column of jaw clamps  415  can likewise move laterally so as not to restrict movement of the glass ribbon  104  and/or apply unintended forces to the glass ribbon  104 . 
     Referring to  FIG. 16 , the separation of the glass ribbon  104  from the another portion of the glass ribbon  104  is illustrated. In some embodiments, before, during, and after the separation, the glass ribbon  104  may be clamped by the first column of jaw clamps  409  and the second column of jaw clamps  415 . In this embodiment, as the glass ribbon  104  moves  1601  along the glass ribbon travel direction  154 , the first column of jaw clamps  409 , the second column of jaw clamps  415 , and the glass ribbon  104  can move  1603 ,  1605  together at the same velocity along the glass ribbon travel direction  154  after clamping the first lateral edge  153  of the glass ribbon  104  with the first column of jaw clamps  409  and the second lateral edge  155  of the glass ribbon  104  with the second column of jaw clamps  415  after the separation of the glass ribbon  104  from the another portion of the glass ribbon  104  has occurred. 
     Referring to  FIG. 17 , in some embodiments, the at least one jaw clamp  423 ,  425 ,  427  of the first column of jaw clamps  409  may be laterally adjustable in the lateral direction  421  relative to the at least one jaw clamp  429 ,  431 ,  433  of the second column of jaw clamps  415 . For example, the first jaw clamp  423  may be laterally adjustable in a first lateral direction  1701 . The first lateral direction  1701  can be oriented towards the first lateral edge  153  of the glass ribbon  104 . The first jaw clamp  423  may be moved along the first lateral direction  1701  when the first jaw clamp  423  is in the clamped or unclamped position. When the first jaw clamps  423 ,  429  are in the clamped position, movement of the first jaw clamp  423  along the first lateral direction  1701  can cause the first jaw clamp  423  to move away from the first jaw clamp  429  of the second column of jaw clamps  415 , thus increasing the tension of the glass ribbon  104 . It will be appreciated that the first jaw clamp  423  may not be limited to moving in the first lateral direction  1701 . Rather, in some embodiments, the first jaw clamp  423  can be moved in a second lateral direction  1703  that can be oriented towards the second lateral edge  155 . When the first jaw clamps  423 ,  429  are in the clamped position, movement of the first jaw clamp  423  along the second lateral direction  1703  can cause the first jaw clamp  423  to move towards the first jaw clamp  429  of the second column of jaw clamps  415 , thus decreasing the tension of the glass ribbon  104 . 
     In some embodiments, the first jaw clamp  429  of the second column of jaw clamps  415  may be laterally adjustable in the first lateral direction  1701  or the second lateral direction  1703  (e.g., as illustrated). The first jaw clamp  429  may be moved along the second lateral direction  1703  when the first jaw clamp  429  is in the clamped or unclamped position. When the first jaw clamps  423 ,  429  are in the clamped position, movement of the first jaw clamp  429  along the second lateral direction  1703  can cause the first jaw clamp  429  to move away from the first jaw clamp  423  of the first column of jaw clamps  409 , thus increasing the tension of the glass ribbon  104 . It will be appreciated that the first jaw clamp  429  may not be limited to moving in the second lateral direction  1703 . Rather, in some embodiments, the first jaw clamp  429  can be moved in the first lateral direction  1701  that can be oriented towards the first lateral edge  153 . When the first jaw clamps  423 ,  429  are in the clamped position, movement of the first jaw clamp  429  along the first lateral direction  1701  can cause the first jaw clamp  429  to move towards the first jaw clamp  423  of the first column of jaw clamps  409 , thus decreasing the tension of the glass ribbon  104 . 
     In these embodiments, at least one jaw clamp of the first column of jaw clamps  409  may be laterally adjustable in the lateral direction  421  relative to at least one jaw clamp of the second column of jaw clamps  415 . For example, methods of manufacturing the glass ribbon  104  comprise adjusting the first lateral spacing  442  between the first jaw clamp  423  of the first column of jaw clamps  409  and the first jaw clamp  429  of the second column of jaw clamps  415  to adjust a first lateral tension of the glass ribbon  104  at the first elevation  441 . For example, the first jaw clamp  423  of the first column of jaw clamps  409  may be moved in the first lateral direction  1701  or the second lateral direction  1703  independent of the first jaw clamp  429  of the second column of jaw clamps  415 . In some embodiments, the first jaw clamp  429  of the second column of jaw clamps  415  may be moved in the first lateral direction  1701  or the second lateral direction  1703  independent of the first jaw clamp  423  of the first column of jaw clamps  409 . In these embodiments, the first lateral spacing  442  between the jaw clamps  423 ,  429  of the first elevational pair  439  of jaw clamps may be adjustable in the lateral direction  421 . 
     In some embodiments, the first lateral spacing  442  between the jaw clamps  423 ,  429  of the first elevational pair  439  of jaw clamps may be adjustable in the lateral direction  421  independent of the second lateral spacing  447  between the jaw clamps  425 ,  431  of the second elevational pair  443  of jaw clamps. Likewise, in some embodiments, the first lateral spacing  442  between the jaw clamps  423 ,  429  of the first elevational pair  439  may be adjustable in the lateral direction  421  independent of the third lateral spacing  453  between the jaw clamps  427 ,  433  of the third elevational pair  452  of jaw clamps. In some embodiments, the first jaw clamp  423  of the first column of jaw clamps  409  may be laterally adjustable independent of the other jaw clamps (e.g.,  425 ,  427 ,  429 ,  431 ,  433 ), while the first jaw clamp  429  of the second column of jaw clamps  415  may be laterally adjustable independent of the other jaw clamps (e.g.,  423 ,  425 ,  427 ,  431 ,  433 ). 
     The first lateral spacing  442  may therefore be adjustable while the second lateral spacing  447  and/or the third lateral spacing  453  can remain unchanged. In some embodiments, the adjusting the first lateral spacing  442  may be conducted independent of the second lateral spacing  447  between the second jaw clamp  425  of the first column of jaw clamps  409  and the second jaw clamp  431  of the second column of jaw clamps  415  at the second elevation  445  of the glass ribbon  104 . By adjusting the first lateral spacing  442 , a first lateral tension of the glass ribbon  104  may be adjusted such that the adjusted first lateral tension of the glass ribbon  104  at the first elevation  441  may be different than a second lateral tension of the glass ribbon  104  at the second elevation  445  of the glass ribbon  104  and/or a third lateral tension of the glass ribbon  104  at the third elevation  451  of the glass ribbon  104 . In some embodiments, the first lateral spacing  442  may be greater than, less than, or equal to the second lateral spacing  447  and the third lateral spacing  453 . 
     Referring to  FIG. 18 , in some embodiments, the second lateral spacing  447  between the jaw clamps  425 ,  431  of the second elevational pair  443  of jaw clamps may be adjustable in the lateral direction  421 . As with the embodiment illustrated and described with respect to  FIG. 17 , the second jaw clamp  425  of the first column of jaw clamps  409  and the second jaw clamp  431  of the second column of jaw clamps  415  may be laterally adjustable in the first lateral direction  1701  or the second lateral direction  1703 . In some embodiments, the second jaw clamp  425  of the first column of jaw clamps  409  may be laterally adjustable independent of the other jaw clamps (e.g.,  423 ,  427 ,  429 ,  431 ,  433 ). In some embodiments, the second jaw clamp  431  of the second column of jaw clamps  415  may be laterally adjustable independent of the other jaw clamps (e.g.,  423 ,  425 ,  427 ,  429 ,  433 ). The second lateral spacing  447  between the jaw clamps  425 ,  431  of the second elevational pair  443  of jaw clamps may be adjustable in the lateral direction  421  independent of the first lateral spacing  442  between the jaw clamps  423 ,  429  of the first elevational pair  439  of jaw clamps. 
     In some embodiments, methods of manufacturing the glass ribbon  104  comprise adjusting the second lateral spacing  447  between the second jaw clamp  425  of the first column of jaw clamps  409  and the second jaw clamp  431  of the second column of jaw clamps  415  to adjust a second lateral tension at the second elevation  445  of the glass ribbon  104 . In some embodiments, due to the second jaw clamps  425 ,  431  being laterally adjustable independent of the other jaw clamps (e.g.,  423 ,  427 ,  429 ,  433 ), the second lateral tension may be adjusted independent of adjusting the first lateral tension. In some embodiments, the first lateral spacing  442  and the second lateral spacing  447  may be adjusted, with the first lateral spacing  442  (and, thus, adjusted first lateral tension) being different than the second lateral spacing  447  (and, thus, adjusted second lateral tension). In this embodiment, by adjusting the first lateral spacing  442  and the second lateral spacing  447  to be different, methods of manufacturing the glass ribbon  104  comprise the adjusted first lateral tension of the glass ribbon  104  being different than the adjusted second lateral tension of the glass ribbon  104 . In some embodiments, the second lateral spacing  447  may be greater than, less than, or equal to the first lateral spacing  442  and/or the third lateral spacing  453 . 
     It will be appreciated that in further embodiments, the third lateral spacing  453  between the third jaw clamp  427  of the first column of jaw clamps  409  and the third jaw clamp  433  of the second column of jaw clamps  415  may be adjusted in a similar manner as the first lateral spacing  442  and the second lateral spacing  447 . For example, the third jaw clamp  427  of the first column of jaw clamps  409  and the third jaw clamp  433  of the second column of jaw clamps  415  may each be laterally adjustable in the first lateral direction  1701  or the second lateral direction  1703 . The third jaw clamp  427  of the first column of jaw clamps  409  and the third jaw clamp  433  of the second column of jaw clamps  415  may each be laterally adjusted independent of the other jaw clamps (e.g.,  423 ,  425 ,  429 ,  431 ). In some embodiments, the third lateral spacing  453  may be greater than, less than, or equal to the first lateral spacing  442  and the second lateral spacing  447 . 
     Referring to  FIG. 19 , in some embodiments, the at least one jaw clamp  423 ,  425 ,  427  of the first column of jaw clamps  409  can be vertically adjustable in the glass ribbon travel direction  154  relative to the at least one jaw clamp  429 ,  431 ,  433  of the second column of jaw clamps  415 . In some embodiments, the first jaw clamp  423 , the second jaw clamp  425 , and/or the third jaw clamp  427  may be moved along a first vertical direction  1901  or a second vertical direction  1903  when the first jaw clamp  423 , the second jaw clamp  425 , and the third jaw clamp  427  are in the clamped or unclamped position. The first vertical direction  1901  may be oriented towards a top edge of the glass ribbon  104  while the second vertical direction  1903  may be oriented towards a bottom edge of the glass ribbon  104 . In some embodiments, one or more of the jaw clamps may be vertically adjustable, such as the first jaw clamp  423  being vertically adjustable independent of the other jaw clamps (e.g.,  425 ,  427 ,  429 ,  431 ,  433 ). 
     In some embodiments, the at least one jaw clamp  429 ,  431 ,  433  of the second column of jaw clamps  415  may be vertically adjustable in the glass ribbon travel direction  154  relative to the at least one jaw clamp  423 ,  425 ,  427  of the first column of jaw clamps  409 . In some embodiments, the first jaw clamp  429 , the second jaw clamp  431 , and/or the third jaw clamp  433  may be moved along the first vertical direction  1901  or the second vertical direction  1903  when the first jaw clamp  429 , the second jaw clamp  431 , and the third jaw clamp  433  are in the clamped or unclamped position. In some embodiments, one or more of the jaw clamps may be vertically adjustable, such as the first jaw clamp  429  being vertically adjustable independent of the other jaw clamps (e.g.,  423 ,  425 ,  427 ,  431 ,  433 ). 
     By providing for an adjustable lateral spacing between the at least one jaw clamp  423 ,  425 ,  427  of the first column of jaw clamps  409  and the at least one jaw clamp  429 ,  431 ,  433  of the second column of jaw clamps  415 , a tension of the glass ribbon  104  along the lateral direction  421  can be adjusted. For example, a tension of the glass ribbon  104  can be adjusted at a plurality of locations along the glass ribbon  104  by adjusting the lateral spacing between the jaw clamps. In some embodiments, the vertical adjustability of the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  can increase or decrease the speed at which the glass ribbon  104  moves along the glass ribbon travel direction  154 . The vertical adjustability can also allow for a tension of the glass ribbon  104  along the glass ribbon travel direction  154  to be adjusted. 
     Referring to  FIG. 20 , a side view of the first jaw clamp  423  of the glass ribbon gripping device  400  is illustrated. In some embodiments, the glass ribbon gripping device  400  may not be limited to applying force to the glass ribbon  104  along the glass ribbon travel direction  154  or the lateral direction  421 . Rather, in some embodiments, the glass ribbon gripping device  400  can apply a force to the glass ribbon  104  along a bending direction  2001  that can be perpendicular to the glass ribbon travel direction  154  and the lateral direction  421 . For example, a machine  2003  can engage the frame  401 , such as by being attached to a rear side of the frame  401  opposite the glass ribbon  104 . The machine  2003  can be configured to move the frame  401  along the bending direction  2001 . In some embodiments, the glass ribbon  104  can extend adjacent to a nosing  2005  at a location upstream (e.g., above) the glass ribbon gripping device  400 . With the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  in the clamped position, the machine  2003  may rotate the frame  401  along the bending direction  2001 . As the frame  401  moves along the bending direction  2001 , the glass ribbon  104  can engage the nosing  2005 , thus causing the glass ribbon  104  to separate from another portion of the glass ribbon  104  (e.g., upstream from the glass ribbon  104 ). 
     In some embodiments of the disclosure, the glass ribbon gripping device  400  can provide for reduced wear of the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  that are in contact with the glass ribbon  104 . For example, due to the potentially high temperatures (e.g., 300° Celsius and higher) that the glass ribbon gripping device  400  may be exposed to, the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  can apply a compressive gripping force when in the clamped position. This compressive gripping force may be higher than achieved in the past with vacuum cup affixation, thus reducing the likelihood of slippage of the glass ribbon  104 . In the event of the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  exhibiting wear due to heat, a gripping force of the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  can be increased to limit slippage of the glass ribbon  104 . Further, the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  may not experience vacuum leaks or vacuum failure that may be common due to tearing or cutting of vacuum cups. 
     In some embodiments, the glass ribbon gripping device  400  can provide for reduced motion and pull-force on the glass ribbon  104  during the scoring and separation process. For example, as illustrated in  FIGS. 9-11 , the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  may be in the unclamped position when the glass ribbon  104  is separated by the glass separator  149 . By being in the unclamped position, the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  may not impart motion or pull-force on the glass ribbon  104 , such that the glass ribbon  104  can move independently of the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433 . After the glass ribbon  104  has been separated, the separated portion of the glass ribbon  104  may engage and rest upon the first support surface  461  and the second support surface  463  prior to the jaw clamps  423 ,  425 ,  427 ,  429 ,  431 ,  433  clamping the glass ribbon  104 . By not contacting the glass ribbon  104  until after the separation has been completed, improved alignment and stability of the glass ribbon  104  can be achieved.
