     This application claims priority to the Non-Provisional patent application Ser. No. 15/899,004 filed Feb. 19, 2018 and entitled Dispenser Cartridge And Wiper, as a continuation in part application, which in turn claims the benefit of the Provisional Patent Application Ser. No. 62/510,448 filed May 24, 2017 and entitled Dispenser Apparatus and Method of Use, In Particular for Laminating and Dispensing Transfer Tape in a Paper Web Turn-Up System, the contents of each of which are incorporated herein by reference in their entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates generally in a first sense to the field of devices, apparatuses and methods of effecting the high-speed severing and transfer of a rapidly advancing paper web from a rotating full web spool onto an empty web spool, and more particularly where such an operation is performed utilizing a transfer or double-sided adhesive turn-up tape. More particularly, the invention relates to an apparatus and method for dispensing transfer tape and its use in a paper web severing/transfer method, wherein the transfer tape is the affecting means for severing, transferring and securing the paper web from a rotating full web spool onto an empty web spool. Additionally, the invention relates in general to a tape dispensing apparatus that dispenses a multi-layer tape useful in various industrial applications. 
     Modern paper manufacturing is typically performed by producing continuous lengths of paper having widths of over 400 inches in some cases, referred to as paper webs, which are wound onto web spools for subsequent converting, storage, transfer or the like. The winding or spooling operation for the paper web, such as in the case of tissue grades, occurs at high speeds, in some cases exceeding 6000 feet per minute, and in order to maximize production by minimizing downtime and waste it is desirable to sever and simultaneously transfer the moving paper web from a full web spool onto an empty web spool without stopping, adjusting draws (i.e. the speed differential between the incoming and outgoing web rotating support members that are not driven by a common source) or slowing the movement of the web. Methods and apparatuses for accomplishing this severing and transfer utilizing what is known as a transfer or turn-up tape have long been known. An early example of such a system is shown in U.S. Pat. No. 2,461,246 to Weyenberg, issued in 1949. Other examples are shown in our U.S. Pat. Nos. 4,659,029, 4,757,950, 4,783,018, 5,046,675, 5,453,141, 5,637,170, and 5,954,290. Further examples and detailed discussion of such equipment, systems and methodologies are present in our U.S. Pat. Nos. 4,659,029, 4,757,950, 4,783,018, 5,046,675, 5,417,383, 5,453,141, 5,637,170, 5,954,290, 6,467,719, 6,578,788, 7,875,152, 8,124,209, 8,178,181 and 8,580,062, the disclosures of which are incorporated herein by reference. 
     The transfer tape utilized in severing and transferring the paper web comprises a substrate having a first adhesive side, the spool mounting side, preferably comprised of a pressure sensitive adhesive (PSA), adapted to contact and adhere to the longitudinal cylindrical surface of the empty web spool. The opposite side of the transfer tape substrate, the web-side (or web grabbing side), has a second adhesive side adapted to contact and adhere to the moving paper web when the rotating empty web spool is brought into contact with the paper web. With the adhesion of the paper web to the empty web spool through this transfer tape, the web is severed from the full web spool and its new leading edge, formed at the severing line created by the transfer tape, adheres to the rotating empty web spool, thus completing the transfer. 
     This invention is of particular application to transfer tapes of the type having a cover flap extending over the web-side adhesive on the substrate of the transfer tape, the cover flap being longitudinally adhered along one edge of the transfer tape, wherein the cover flap is provided with a release coating, such as a silicone layer, over the majority of the side of the cover flap facing the adhesive side. With this construction, the cover flap remains closed to protect the web-side adhesive from contaminants such as dust and debris until the empty web spool is spun up to its speed to match the speed of the web. As the empty web spool rotates the cover flap peels back due to aerodynamic effects, pulling the release-coated section of the flap away from the adhesive. The cover flap opens at its leading edge, which is the edge of the transfer tape first encountering the resulting airstream due to the rotation of the empty web spool. The cover flap remains attached to the web-side adhesive at the trailing edge of the transfer tape due to the flap being void of the silicone release layer in that narrow region. The transfer tape is now in a state with its protective cover flap peeled back to expose the fresh and uncontaminated adhesive and is able to adhere to the subject paper web to sever and transfer it to the empty web spool. Examples of such transfer tapes are shown in U.S. Pat. Nos. 8,124,209 and 8,178,181. 
     The high-speed transfer of lightweight paper webs, such as groundwood papers (including, for example, newsprint) or tissue paper, is more difficult to accomplish due to the weaker structure of the paper. In addition, in systems using adhesive transfer tapes for the web transfer, the exposed adhesive side of the transfer tape is often contaminated with airborne dust, floating paper fibers and other debris, which are prevalent with the lightweight paper webs, such that the adhesion is weakened or even substantially blinded, which can result in a failed transfer. A failed transfer results in lost production, inconsistent winding of the product and inconsistent roll sizes, excessive waste, shorter service life of the fiber cores which are commonly used in tissue making machines, and unsafe operating conditions. 
     Thicker transfer tape substrates are preferable as the thicker tape makes more complete contact with rotating web spools having fiber cores, as the core surfaces of the empty web spool are not always concentric to its spinning axis, possibly resulting in relatively large gaps when the empty core is brought into contact with the web. Voids and gaps may also be present in the fiber cores themselves, and thicker substrates are better at filling the gaps to present the adhesive to the moving web. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of this invention to provide an apparatus and method addressing the contamination problem of the exposed adhesive on the transfer tape. It is a further object to provide such an apparatus and method that allows for the transfer tape to be dispensed in the desired length as needed for performing the turn-up operation. It is a further object to provide an apparatus and method adapted for use in many different industrial applications. 
     It is also an object of this disclosure to provide embodiments of transfer tape design comprising a cord or filament that is included into the structure of the transfer tape and provides support and stiffening of the transfer tape. In some preferred embodiments, the transfer tape may include a cord that contains material suitable to be re-pulped and included in the paper product. The suitability to be re-pulped may significantly reduce waste in paper processing. 
     The apparatus comprises a dispenser housing for dispensing a multi-layer tape, and in particular a paper web transfer tape, the housing containing a transfer tape spool. The transfer tape is a laminated composite of a zone-coated release liner and a transfer tape base or substrate, the transfer tape substrate having a pressure sensitive adhesive (PSA) on both sides. The release liner is comprised of a paper substrate with a release coating on both sides. The release coating on the side facing the PSA does not cover the entire surface, such that a longitudinally extending strip of the release liner substrate paper along one edge is free of the release coating so as to define a cover flap. With this construction, the cover flap is effectively hinged to the PSA transfer tape substrate. The uncoated zone provides a strong adhesion of the cover flap to the PSA. This adhesion zone retains the cover flap to the PSA even when the cover flap opens to expose the PSA for the turn-up operation. It is important that the cover flap remain attached to the PSA during the time it is open. If the cover flap were to detach from the PSA the loose cover flap could become entangled in the high-speed equipment, interfering with its proper operation, or it could interfere with the fragile paper web, causing it to rupture. 
     The dispenser cartridge is an enclosure which prevents dust and other particulates from contacting the components, especially any exposed PSA, while the laminated transfer tape is awaiting use for application to the empty web spool. The cartridge dispenses the transfer tape outside of the enclosure through a small slot. The dispenser cartridge preferably contains a wiper blade, preferably made of a semi-rigid, flexible but resilient, material, to wipe or press the transfer tape onto the empty web spool. This is valuable since the transfer tape is relatively wide and the empty web spool presents a cylindrical surface. The wiper blade presses on the release liner/cover flap of the transfer tape, that is the web-grabbing side of the tape, and flexes as necessary to conform the transfer tape to the curved surface of the web spool. In this way the wiper blade helps to assure a uniform adhesion of the PSA of the transfer tape to the empty web spool. The dispenser cartridge may be a stand-alone assembly such that the operator manipulates the dispenser cartridge along the empty web spool by hand, or the dispenser cartridge may be adapted for use within a secondary housing, or for use in dispensing equipment or apparatus, whether fixed, moving or handheld. The dispenser cartridge may be designed, structured and adapted to be a replaceable assembly removed from a secondary external unit, equipment or the like when empty, with a full cartridge then inserted in its place. 
     The orientation of the transfer tape as wound onto the transfer tape spool is critical to prevent undesirable buckling of the release liner relative to the PSA-coated base. The PSA layer is relatively thicker and more elastic in comparison to the release liner, which is formed of a paper-based material. While the release liner is flexible enough to be wound around the transfer tape spool, it will not stretch or compress as much as the PSA layer. If the transfer tape is wound onto the tape spool with the PSA-coated substrate on the inside and the release liner on the outside, which is the typical orientation, when a segment of transfer tape is unrolled and flattened as it is applied to the empty web spool the release liner buckles due to the differential in length of the release liner relative to the PSA-coated substrate. To address this problem, the transfer tape is wound onto the transfer tape spool with the PSA-coated substrate on the outside and the release liner on the inside. When unrolled and applied to the surface of the empty web spool, the release liner is shorter than the PSA layer and will be pulled tight, thereby eliminating the buckling problem. Thus, the apparatus provides for the application of transfer tape in optimal condition in the required length as needed for the web turn-up transfer operation. 
     Alternatively, the invention may be summarized and described as a transfer tape cartridge dispenser comprising transfer tape with an incorporated cord feature wound onto a transfer tape spool within a housing, said housing having a slot adapted such that said transfer tape passes through said slot as it is unwound; said transfer tape adapted to sever and secure a paper web from a first web spool onto an empty web spool in a web turn-up operation, said transfer tape comprising a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, said release layer being of a material that prevents adhesion of the adhesive to the release liner substrate; said zone-coated release layer defining a longitudinally extending uncoated joining region on said release liner substrate, whereby said web grabbing adhesive adheres to the said uncoated joining region of said release liner substrate such that said zone-coated release layer defines a cover flap not adhered to said web grabbing adhesive; said transfer tape being wound onto said transfer tape spool with said release liner facing inward and said mounting side adhesive facing outward, such that said release layer fully coated on said first side of said release liner substrate prevents adhesion of said mounting side adhesive to said release liner substrate. Furthermore, also provided is such a transfer tape cartridge dispenser, wherein said adhesive is a pressure sensitive adhesive; wherein said uncoated joining region of said release liner substrate extends along a longitudinal edge of said release liner substrate; further comprising a wiper mounted on said housing adjacent said slot, said wiper adapted to apply pressure to said transfer tape when said transfer tape is applied to said empty web spool; wherein said wiper is permanently mounted onto said housing; wherein said wiper is removably mounted onto said housing such that said wiper is reusable with other said dispenser cartridges; wherein said web grabbing adhesive is thicker than said release liner; wherein said web grabbing adhesive is more elastic than said release liner; and/or wherein said web grabbing adhesive is more compressible than said release liner. 
     Alternatively still, the invention may be summarized and described as a transfer tape cartridge dispenser comprising transfer tape with an incorporated cord feature adapted to sever and secure a paper web from a first web spool onto an empty web spool in a web turn-up operation, said transfer tape wound onto a transfer tape spool within a housing, said housing having a slot adapted such that said transfer tape passes through said slot as it is unwound and a wiper mounted on said housing adjacent said slot, said wiper adapted to apply pressure to said transfer tape when said transfer tape is applied to said empty web spool; said transfer tape comprising a tape substrate coated on one side with a web grabbing pressure sensitive adhesive and on the other side with a mounting pressure sensitive adhesive, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, said release layer being of a material that prevents adhesion of the pressure sensitive adhesive to the release liner substrate; said zone-coated release layer defining a longitudinally extending uncoated joining region on a longitudinal edge of said release liner substrate, whereby said web grabbing adhesive adheres to the said uncoated joining region of said release liner substrate such that said zone-coated release layer defines a cover flap not adhered to said web grabbing pressure sensitive adhesive; wherein said web grabbing pressure sensitive adhesive is thicker, more elastic and more compressible than said release liner; said transfer tape being wound onto said transfer tape spool with said release liner facing inward and said mounting side pressure sensitive adhesive facing outward, such that said release layer fully coated on said first side of said release liner substrate prevents adhesion of said mounting side pressure sensitive adhesive to said release liner substrate. 
     Alternatively still again, the invention may be summarized and described as a method of dispensing and applying a transfer tape with an incorporated cord feature onto an empty web spool to sever and secure a paper web from a first web spool onto an empty web spool in a web turn-up operation comprising the steps of: winding said transfer tape onto a transfer tape spool within a dispenser cartridge housing and extending said transfer tape through a slot in said housing a slot adapted such that said transfer tape passes through said slot; said transfer tape comprising a tape substrate coated on one side with a web grabbing pressure sensitive adhesive and on the other side with a mounting pressure sensitive adhesive, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, said release layer being of a material that prevents adhesion of the pressure sensitive adhesive to the release liner substrate; said zone-coated release layer defining a longitudinally extending uncoated joining region on a longitudinal edge of said release liner substrate, whereby said web grabbing adhesive adheres to the said uncoated joining region of said release liner substrate such that said zone-coated release layer defines a cover flap not adhered to said web grabbing pressure sensitive adhesive; wherein said step of winding said transfer tape onto said transfer tape spool comprises winding said transfer tape onto said transfer tape spool with said release liner facing inward and said mounting side pressure sensitive adhesive facing outward, such that said release layer fully coated on said first side of said release liner substrate prevents adhesion of said mounting side pressure sensitive adhesive to said release liner substrate. Furthermore, the method further comprising the step of passing a segment of said transfer tape through said slot and applying said transfer tape to said empty web spool, pressing said transfer tape onto said empty web spool using a wiper, and cutting said segment of transfer tape; and/or wherein said step of applying said transfer tape to said empty web spool comprises orienting said transfer tape on said empty web spool such that said cover flap extends in the direction of rotation of said empty web spool. 
     Alternatively, a transfer tape may be formed by assembling a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, said release layer being of a material that prevents adhesion of the adhesive to the release liner substrate, and a cord affixed to the tape substrate. In some examples, the cord may be adhered to the mounting adhesive. In other examples, the cord may be adhered, potentially with a pressure sensitive coating, to the web grabbing adhesive. In some examples, the zone-coated release layer may define a longitudinally extending uncoated joining region on said release liner substrate. The web grabbing adhesive may adhere to the said uncoated joining region of the release liner substrate such that said zone-coated release layer defines a cover flap not adhered to the web grabbing adhesive. In some examples, the cord may define an elevated surface profile of the transfer tape proximate to the cord when the transfer tape is adhered to a surface.

     DETAILED DESCRIPTION OF THE INVENTION 
     With reference to the drawings, which are provided for descriptive and illustrative purposes are which are not meant to be limiting as the scope of the invention, the invention in various embodiments in a broad and general sense is an apparatus and a method for dispensing a multi-layer adhesive tape, and in particular a transfer tape used in a paper web turn-up operation, wherein a continuous paper web being rolled onto a first web spool is severed and transferred to an empty second web spool when the first web spool is fully wound, the transfer occurring without requiring the flow of the paper web to be temporarily altered or stopped. It is to be understood that disclosure of the apparatus and method in relation to a paper web turn-up operation is an exemplary disclosure not meant to be limiting, as the dispenser structure as described is suitable for the production of different types of tapes for different industrial applications. It is to be understood that the dispenser cartridge may be a stand-alone assembly such that the operator manipulates the dispenser cartridge along the empty web spool by hand, or the dispenser cartridge may be adapted for use within a secondary housing, for use in dispensing equipment, whether stationary or mobile, etc. The dispenser cartridge may be designed, structured and adapted to be a replaceable assembly removed from a secondary external unit, equipment or the like when empty with a full cartridge then inserted in its place. 
     The transfer tape  20 , an embodiment of which is shown in  FIGS. 1 and 2 , is a laminated composite of a transfer tape base or substrate  31  and a zone-coated release liner member  21 . The transfer tape substrate  31  is composed of a paper stock member (or a member composed of similar, suitable material, most preferably re-pulpable) of sufficient strength, thickness, texture and stiffness to accomplish the turn-up transfer operation without breaking or separating throughout its subsequent use. Both sides of the transfer tape substrate  31  are coated, layered or laminated with an adhesive, preferably a pressure sensitive adhesive (PSA), suitable for attaching one side (the mounting side) of the laminated transfer tape  20  to an empty paper web spool and the other side (the web side) to a paper web of tissue or the like. The PSA  32 A on the mounting side may have different properties compared to the PSA  32 B on the web grabbing side. These different properties may include adhesion, tackiness, color, or thickness, among others. 
     The release liner member  21  comprises a release liner substrate  22 , preferably composed of a re-pulpable material, that is fully coated on its exposed side with a release layer or coating  24  composed of a material, such as silicone, that has very low adhesion to the PSA  32 . With this coating, the mounting side PSA  32 A will not adhere to the release liner substrate  22  when the transfer tape  20  is wound onto the transfer tape spool  12  of the dispenser cartridge  10 , as the winding places the mounting side PSA  32 A in contact with the release layer or coating  24 . The opposite or interior side of the release liner substrate  22  is zone-coated with a suitably chosen release layer or coating  23  that prevents adhesion of the web grabbing PSA  32 B to the release liner substrate  22 . This non-adhering portion of the release liner substrate  22  defines the cover flap  26  which temporarily covers and then opens to expose the web grabbing PSA  32 B during the turn-up operation as explained. 
     The zone-coated release layer  23  only covers a majority of the interior side of the release liner substrate  22 , such that a longitudinal strip or zone along or near one longitudinal edge of the release liner substrate  22  is left uncoated and defines a longitudinally extending uncoated joining region  25 . When the two components are laminated together to form the transfer tape  20 , the region of the web grabbing side release liner  21  corresponding to the uncoated joining region  25  adheres the release liner substrate  22  to the transfer tape substrate  31  along an edge (the trailing edge when in use), thus creating in effect a hinge and defining the cover flap  26  that is free to open. 
     In one embodiment of the transfer tape  20  the release liner  21  is wider than the tape substrate  31 , such that the cover flap  26  extends beyond the unattached edge of the tape substrate  31 . When the transfer tape  20  is applied to the empty web spool this overhang is the leading edge of the tape  20 , facing into the direction of rotation of the empty web spool when it is spun up for the turn-up operation. The overhang portion of cover flap  26  catches the air caused by the high-speed rotation of the empty web spool. This aerodynamic affect causes the cover flap  26  to peel back and expose the web grabbing side PSA  32 B so as to adhere to and sever the web. 
     Rather than supplying short segments of transfer tape  20 , it is much more economical and efficient to provide the transfer tape  20  as a wound roll which is then cut into the appropriate lengths when needed. The orientation of the transfer tape  20  as wound onto a transfer tape spool  12  is critical to prevent undesirable buckling of the release liner  21  relative to the PSA-coated tape substrate  31 . The web grabbing side PSA layer  32 B is relatively thicker, more elastic and more compressible in comparison to the release liner  21 . While the release liner  21  is flexible enough to be wound around the transfer tape spool  12 , it will not stretch or compress as much as the web grabbing side PSA layer  32 B. If the transfer tape  20  is wound onto the tape spool  12  with the PSA-coated tape substrate  31  on the inside and the release liner  21  on the outside, which is the typical orientation, when a segment of transfer tape  20  is unrolled and flattened as it is applied to the empty web spool the release liner  21  buckles due to the differential in length and elasticity of the release liner  21  relative to the web grabbing side PSA layer  32 B. This buckling may interfere with the proper opening of the cover flap  26 . To solve this problem, the transfer tape  20  is wound onto the transfer tape spool  12  with the PSA-coated substrate  31  on the outside and the release liner  21  on the inside, as shown in  FIG. 3 . When unrolled and applied to the surface of the empty web spool, the release liner  21  is shorter than the web grabbing side PSA layer  32 B and will be pulled tight, thereby eliminating the buckling problem. 
     To maintain the pre-wound transfer tape  20  in a clean state, the roll of transfer tape  20  and tape spool  12  are contained within a dispensing cartridge. In a basic version, the dispenser cartridge comprises a housing  11  or enclosure having a top panel, a bottom panel and four side panels, although it is not essential that the housing  11  be rectangular. The housing  11  is constructed such that it is substantially sealed in the sense that dust and particulates are prevented from entering the housing  11  to contaminate the transfer tape  20 . The transfer tape  20  is then dispensed through a slot  13  in the dispenser cartridge housing  11 . The laminated transfer tape  20  is caused to move through the dispensing cartridge  10  by any of several methods, including manually pulling the tape  20  from the dispenser cartridge  10 . The dispensing cartridge also comprises a semi-rigid wiper  14  to properly contour and uniformly adhere the mounting side PSA  32 A to the empty web spool. The wiper  14  may be a component manufactured into the dispensing cartridge  10  or may be a component that is subsequently attached to the dispensing cartridge by the operator. A cutter adjacent the slot (not shown) may be provided to sever the desired length of transfer tape  20 . The cutter may also be a device to perforate the transfer tape  20  for manual separation by the operator, or the cutter may be a separate device such as a scissors. The length of product to be dispensed is determined by the operator. 
     The dispensed transfer tape  20  is applied to the empty web spool. The mounting side PSA  32 A of the transfer tape  20  is oriented toward the longitudinal surface of the empty web spool and the web-grabbing PSA side  32 B or cover flap  26  of the transfer tape  20  is oriented facing outward, away from the empty web spool. The transfer tape  20  is oriented on the web spool such that the leading edge of the cover flap  26 , which is the edge that will open, is facing into the airstream that will result when the empty web spool is rotated up to speed to match the line speed of the paper web. Conversely, the trailing edge of the transfer tape  20 , which is the edge of the tape  20  where the cover flap  26  is hinged and retained, is facing away from the airstream of the rotating empty web spool. 
     In a first embodiment of the dispenser cartridge shown in  FIGS. 4-6 , the semi-rigid wiper  14  is a separate member that is attached to the dispenser cartridge housing  11  by the operator. The wiper  14  and the cartridge housing  11  contain complimentary structural features to facilitate easy attachment. The wiper  14  is a corner piece formed to align with a corner of the cartridge housing  11 . Further, the wiper  14  may be provided with tabs  16  or prongs which in the embodiment as shown align with pre-formed or pre-slit receiving slots or areas  17  of the cartridge housing  11 . Alternatively, when the housing  11  is composed of a suitable material such as corrugated cardboard or a similar material, the tabs  16  are structured to be piercing members, and aligning the wiper  14  to the cartridge housing  11  is accomplished by pressing the two together causes the tabs  16  to pierce the housing  11  at the receiving areas  17 . The tabs  16  are forced into the receiving areas  17  and achieve a suitable frictional engagement that is sufficient to retain the two components together until the dispenser cartridge  10  is emptied of its transfer tape  20 , which is mounted onto a hub  18 . When the cartridge  10  is emptied the wiper  14  is easily removed by the operator by reversing the relative motion applied to assemble the two and the wiper  14  is then re-used on another cartridge  10 . 
     Another alternative embodiment is shown in  FIGS. 7 and 8 . In this embodiment the semi-rigid wiper  14  is an inexpensive, generally planar member that may be preinstalled with the completed dispenser cartridge  10  or later inserted by the operator into a tab receiving slot or areas  17 . This simple blade wiper  14  and housing  11  have complementary features to engage and securely retain the wiper  14  through its use. 
     The dispenser cartridge  10  may contain features to retain the enclosed roll of transfer tape  20  such that the unwound portion of tape  20  protruding through the exit slot  13  does not retract back through the exit slot  13  into the housing  11 , making it inaccessible to the operator. These features may consist of a centering device or hub  18  to hold the roll essentially in place inside the enclosure, but allowing the tape  20  to unwind as needed for proper dispensing. This hub  18  could be constructed to allow one-way rotation of the tape roll  20 , that is in the unwinding direction, but not allow rotation of the tape roll  20  such that it would retract the protruding tape portion back into the housing  11 . Further features may include a means to hold or retain the unwound portion of the tape  20  such as a surface to adhere a short portion of the exposed PSA  32 A as is commonly done in well-known tape dispensers. Such features as described may be used in any combination. 
     In addition to being manually pulled from the dispenser cartridge  10 , the cartridge may be motorized or otherwise powered to rotate the transfer tape spool  12 , or guide rolls or drive rolls may be utilized to expel the transfer tape  20  from the cartridge  10  as needed. The dispenser cartridge  10  may be a stand-alone assembly such that the operator manipulates the dispenser cartridge  10  along the empty web spool by hand, or the dispenser cartridge  10  may be adapted for use within a secondary external housing, or for use in dispensing equipment or apparatus, whether fixed, moving or handheld. The dispenser cartridge  10  may be designed, structured and adapted to be a replaceable assembly removed from a secondary external unit, equipment or the like when empty, with a full cartridge  10  then inserted in its place. 
     Transfer Tapes with Cord Elements 
     In some embodiments, the transfer tape may further include features formed by cord or cord like elements. A cord may be a woven, braided, or twisted collection of fibers that may be flexible and movable much like the transfer tape substrate. In other examples, a cord may be a single fiber element that has properties much like a woven, braided or twisted collection of fibers. In preferred embodiments, the cord or cord like elements may be formed of materials that are re-pulpable or that may dissolve upon a processing to repulp waste material including the transfer tapes. Cords may be formed of paper, paper fibers, or similar material. The incorporation of cords or cord like elements may impart a number of characteristics to the transfer tape including stiffening the tape, interconnecting the tape, and importantly it may give an attached transfer tape a profile thickened in the portion of the tape connected to the cord. 
     Referring to  FIG. 9 , an exemplary transfer tape  120  with a cord element  100 , an embodiment of which is shown in  FIGS. 9, 10 and 11 , is a laminated composite of a transfer tape base or substrate  31  and a zone-coated release liner member  21 . The transfer tape substrate  31  may be composed of a paper stock member (or a member composed of similar, suitable material, most preferably re-pulpable) of sufficient strength, thickness, texture and stiffness to accomplish the turn-up transfer operation without breaking or separating throughout its subsequent use. In some examples, a thin tissue like paper may be used as a substrate. Both sides of the transfer tape substrate  31  may be coated, layered or laminated with an adhesive, preferably a pressure sensitive adhesive (PSA)  32 , suitable for attaching one side (the mounting side) of the laminated transfer tape  120  to an empty paper web spool and the other side (the web side) to a paper web of tissue or the like. The PSA  32 A on the mounting side may have different properties compared to the PSA  32 B on the web grabbing side. These different properties may include adhesion, tackiness, color, or thickness, among others. A cord  100  may be placed upon the PSA  32 A. In some examples, the cord  100  may be centered upon the transfer tape substrate  31 . In other examples, it may be placed at a non-centered location. 
     In the example of the illustration of  FIG. 9 , the cord  100  may be adhered with the PSA  32 B and the cord itself may not be coated with any adhesive (in other embodiments the cord may be partially or entirely coated with an adhesive). It may function to provide a spacing or surface topography/profile of the tape upon the empty web spool. The profile may create a pressure when the empty web spool interacts with a paper web. 
     Continuing with  FIGS. 9 and 10 , the release liner member  21  may comprise a release liner substrate  22 , preferably composed of a re-pulpable material, that is fully coated on its exposed side with a release layer or coating  24  composed of a material, such as silicone, that has very low adhesion to the PSA  32 . With this coating, the mounting side PSA  32 A will not adhere to the release liner substrate  22  when the transfer tape  120  is wound onto the transfer tape spool  12  of the dispenser cartridge  10 , as the winding places the mounting side PSA  32 A in contact with the release layer or coating  24 . The opposite or interior side of the release liner substrate  22  is zone-coated with a suitably chosen release layer or coating  23  that prevents adhesion of the web grabbing PSA  32 B to the release liner substrate  22 . This non-adhering portion of the release liner substrate  22  defines the cover flap  26  which temporarily covers and then opens to expose the web grabbing PSA  32 B during the turn-up operation as explained. And, as previously mentioned an underlying cord may raise portions of the web grabbing PSA  32 B coated surface. The elements of the illustrated transfer tape  20  with attached cord  100  may be configured in the various manners as have been described herein. 
     Referring now to  FIG. 11 , the elements of the illustrated transfer tape  120  may be properly wound into a coil, having the tape substrate on the outside and the release liner on the inside to address buckling problems as previously discussed. The cord, attached to the tape substrate may, accordingly, be wound into the coil interacting with the release surfaces of the release liner member  21  of the underlying wound transfer tape. 
     A transfer tape  220  may have a cord or cord like feature incorporated in different manners. As illustrated in  FIG. 12 , in some examples, the cord  200  or cord like feature may be embedded or incorporated into the transfer tape substrate  31 . For example, a paper cord, formed of braided and wrapped paper strands, may be pressed into a paper pulp during the formation of the paper transfer tape substrate  31 . In other examples, the substrate may be formed of alternative materials where a protruding surface of the cord like element may be formed directly into the transfer tape substrate  31 . As mentioned, the paper transfer tape substrate, in preferred examples, may be re-pulpable or it may be dissolvable when spare material waste, such as at the end of a spool, is recycled. In examples where the transfer tape substrate  31  is formed directly with a cord like feature, the shape may be different from the illustrated round feature, such as with a hemispherical shape protruding on one surface only. The cord  200  or cord-like feature may be coated with PSA  201 . 
     Proceeding to  FIG. 13 , a transfer tape  320 , may be assembled with a cord  300  or cord like feature on the opposite side of the of the transfer tape substrate  31 . If the cord  300  is on the opposite side, it may face up towards a paper web during turn-up. Accordingly, in some examples, the cord  300  or cord-like feature may be, itself, coated with pressure sensitive adhesive  301 . It may be the same PSA as the PSA 32 B on the web grabbing PSA surface in some examples. The release liner member  21  may be dimensioned to accommodate the additional surface area due to the cord  300 , and in some examples, the release liner may have a bent shape when assembled into the transfer tape  320 .
