FIELD OF THE INVENTION 
     This invention relates to an automated screening machine that automatically adjusts for different size window screen frames, and automatically clamps the window screen frame from the interior perimeter of the window screen frame to prevent bowing of the window screen frame. More particularly, the screening machine automatically inserts the spline and the screen into the spline groove on all four sides in one continuous cycle without turning of the window screen frame, such that one continuous piece of spline is inserted in the entire perimeter of the window screen frame, and the machine automatically trims the excess screen material from the window screen frame and the screen roll. 
     BACKGROUND OF THE INVENTION 
     Standard window screens for homes, offices, trailers, RV&#39;s and the like include a rectangular screen frame which consists of an aluminum or steel frame having a fiber mesh screen material made of nylon, metal, fiberglass, or plastic being held in place with flexible spline material made of rubber or soft plastic. The screen material is placed over the screen frame and the spline material is rolled into the grooved channel on the screen frame which tightly secures the screen mesh material to the screen frame. The prior practice for securing the spline material and fabric mesh screen to a screen frame included a rolling procedure or a spline-positioning procedure in which a small hand-held roller or a semi-automatic, but manually-operated, window screen assembly were used to accomplish the aforementioned task. These tools and devices for window screen assembly still require manual dexterity and physical strength in which to operate these appliances. 
     The use of this type of a manual tool or a semi-automatic manual device makes it difficult for prolonged production runs, as some of the operators developed arm-related medical injuries, such as tendinitis, which resulted in lost production time, lost wages and increased cost of goods manufactured. 
     Prior art automated window screen assembly devices for securing the spline material and the fabric mesh screen to a screen frame have complex clamping mechanisms which require the device to assure parallelism of the frame members. In addition, these automated devices have complex spline-loading and feeding mechanisms, such that the spline feed assembly and spline head assembly had to move at the same speed to apply spline to the screen frame correctly. Spline loading is complicated and the spline path followed is tortuous, as the spline feed assembly is powered. The spline feeding mechanisms of these automated devices have a round spline wheel for inserting the spline material into the spline grooved channel. This was not done effectively as the spline did not get pushed completely into the square corner. Further, these devices do not automatically detect frame size; so the operator had to know the exact size of the frame and program the frame size into the machine&#39;s computer component via a keyboard. In operation with many different sizes, this is very time-consuming and this step added to the cost of manufacture. 
     The existing automatic window screen devices have other ineffective operational steps where the screen material was cut from the screen roll only when the screen was completely splined which added to the cost of manufacture. In summary, the existing automatic window screen assembly devices are overly complex, bulky, and ineffective in operation which increase the cost of manufacture. 
     There remains a need for an automated window screening assembly machine that will automatically adjust for different size window screen frames, and will automatically clamp the window screen frame from the interior perimeter of the window screen frame to prevent bowing of the window screen frame. Additionally, the screening machine should automatically insert the spline and the screen material into the spline groove on all four sides in one uninterrupted cycle without turning of the window screen frame, such that one continuous piece of spline is inserted in the entire perimeter of the window screen frame, and the machine should automatically trim the excess screen material from the window screen frame and the screen roll. Further, the automated window screening assembly machine should be of simple design for ease of manufacturing, which will increase productivity and lower the cost of manufacture of a window screen. 
     DESCRIPTION OF THE PRIOR ART 
     Window screen assembly apparatus of various designs, structures, styles ad materials of construction have been disclosed in the prior art. For example, U.S. Pat. No. 4,899,429 to Londono is directed to a hand tool for installing a pliable spline in a screen frame. The tool includes a front roller having a convex edge for pushing the screen into the channel of a screen frame, and a back roller having a concave edge for pushing the spline material into the channel over the screen. 
     U.S. Pat. Nos. 5,052,093 and 5,127,143 to Urlacher are directed to apparatus for inserting a flexible spline into a screen frame. The apparatus includes a carriage which is slidably mounted along one edge of a horizontal tabletop. The carriage includes a roller mounted on a bracket assembly which may be raised or pivoted between an upper inoperative position and a lower operative position With the carriage in the proper inoperative position, a screen frame is placed against the edge of the table and the screen material is positioned over the frame. The carriage is then moved to one end of the frame and lowered into the operative position, whereby the edge of the roller forces the screen material and a spline into a channel in the frame. The carriage is then manually moved along the length of the frame to the opposite end, whereupon it is moved to the inoperative position, the screen frame is rotated 90 degrees, and the carriage is again lowered into its operative position to push the spline and screen material into the channel in the end of the frame. The procedure is repeated for the remaining two sides of the screen frame. Excess screen material is manually removed with a knife blade, and the spline is also cut manually with a knife blade after the screen has been completed. 
     U.S. Pat. No. 5,069,739 to Kautt is directed to an automated machine for fitting and cutting the seals of a window. The apparatus includes a carriage which is mounted on a gantry for movement in two directions in a horizontal plane. A manipulator head is mounted to the carriage via a vertical shaft for rotation among four positions oriented at 90 degrees to one another. One unit of the manipulator head includes a seal fitting roller and a guide roller, as well as a device for cutting the seal at the desired length. The other unit of the manipulator head includes a suction chamber which is pivotally mounted thereto, the suction chamber serving to hold the seal after it is cut, to bend it and to press it against the surface of the window frame. Each unit is independently moveable by a rack and pinion system. The First unit in a lowered position applies the seal to the window frame and, after a certain length of travel of the manipulator head, the second unit is lowered into contact with the already deposited seal. As the manipulator head nears the end of its travel, the first unit is raised and the cutting device is actuated to cut the seal which is then held against the suction chambers of both units. Subsequently, the suction chamber of the second unit is pivoted downwardly to press the cut end of the seal against the window frame. The entire manipulator head is then rotated 90 degrees and the procedure is repeated. 
     U.S. Pat. No. 2,753,897 to Conrad discloses a device for assembling framed screens. According to this reference, the apparatus consists of a rectangular support surface having vertically moveable floating carriers that are disposed along the perimeter thereof. A spline 84 is positioned in the channel between the vertically moveable carriers and a piece of screening cut to the proper size is then placed on the support surface overlying the splines. The screen frame is then placed above the sheet of screening so that the grooves are aligned above the spline. The entire assembly is then slid beneath a platen which presses the frame downward, forcing the edges of the screening and the splines into the grooves in one action. Once the platen is raised, the completed screen is removed from the support surface and the entire process is repeated for the next screen. 
     U.S. Pat. No. 3,851,684 to Wyrick discloses an apparatus for automatically assembling a flexible sheet of material, such as screening, to a frame. The apparatus consists of a work table to which a frame is secured in a stationary position. A length of screen material is pulled across the frame where it is temporarily clamped in place and tensioned. A first moveable carriage having a first pair of pressing rollers traverses a first pair of opposed parallel frame members, pressing the edges of the screen material into the spline grooves disposed therein. Once this step has been completed, the first moveable carriage reverses direction and returns to the starting position, during which time a second moveable carriage having a second pair of pressing rollers is activated to travel in a transverse direction, the second pair of pressing rollers pressing the transverse edges of the screen material into the spline grooves located in the second pair of parallel frame members. This patent is silent both as to how the length of screen is cut from the supply spool and how the excess screen is trimmed from the edges of the frame. 
     U.S. Pat. No. 4,766,661 to Croteau discloses another apparatus for automatically attaching a fabric material to a rectangular frame. The apparatus consists of a planar frame support surface disposed on a support structure. Two pairs of opposed parallel frame-engaging members include gripping means for holding the frame members securely in place. 
     Two of the frame engaging members transverse to one another are displaceable to assure that the individual frame members are assembled in a parallel manner. A length of screen material is positioned over the frame to overlie the spline grooves located in the frame members. A spline positioner is then actuated to position and push the spline into the retention groove, while at the same time trimming the excess screen material along the exterior of the groove. 
     A control module programmed with the dimensions of the rectangular frame controls the movement of the spline positioner so that a the spline positioner reaches a corner of the frame the spline positioner is lifted, rotated 90° and lowered to press the edge of the screen and spline into the adjacent frame member. When a predetermined length of spline corresponding to the perimeter dimension of the rectangular frame has been fed through the spline positioner, the spline is severed. A separate cutting device cuts the screen across its width to sever the finished screen from the supply roll of screen material. U.S. Pat. Nos. 5,666,773 and 5,787,657 to Librande et al disclose a method and apparatus for securing a screen to a window frame. The window screen includes operator elements that secure the window screen relative to a window frame. A pair of single rail operators releasably secure the upper end of the screen relative to the upper end of the window frame. A pair of double rail operators releasably secure the lower end and sides of the screen relative to the lower end and sides of the window frame. 
     U.S. Pat. No. 5,794,328 to Simone discloses a splining apparatus for seating an elongated flexible spline in the screen retaining channel of a screen frame to secure flexible screen material thereto, including a work support assembly for receiving and holding the screen fame, and a carriage assembly for longitudinal movement between a first position and a second position. The splining apparatus also includes an electronic sensor for sensing he end of the screen frame and for stopping the movement of the spline head assembly at the second position.

     OPERATION OF THE PRESENT INVENTION 
     STEP A. 
     Start-up and Apparatus Initialization 
     When the power switch  1094  located on the movable control panel  1070  is switched to the “ON” position by the operator, electrical power enables the main contactor  1032  which then supplies power to the computer control module  1002 , the main power supply  1004  and the servomotor controllers  1034 ,  1036 ,  1038 ,  1040 ,  1042  and  1044 , as shown in FIG. 20 of the drawings. The operator then waits for the touch screen display  1082  to display “Press to Initialize”, such that the operator then depresses the touch screen display  1082  to initialize apparatus  10 . 
     The automatic screening apparatus  10  will initialize as follows: 
     The computer control module  1002  will send a signal to the rear clamping slide servomotor controller  1044  and this will then enable the rear clamping slide servomotor  170 , such that the rear clamping slide servomotor  170  will rotate the rear frame clamp drive bar belt  166  which will rotate the rear frame drive bar  164 . This action will then move the rear side frame clamp assembly  700  toward the rear frame clamping slide home sensor  1056 . When the rear side frame clamp assembly  700  has reached the rear frame clamp home sensor  1056 , the rear frame clamping slide servomotor  170  will stop. This is the home position  60  for the rear side frame clamp assembly  700 . The next apparatus  10  movement is the clamping slide carriage assembly  600  going to a home position as follows: The computer control module  1002  will send a signal to the clamping carriage servomotor controller  1042  and this signal will enable the clamping carriage servomotor  154  such that the clamping carriage servomotor  154  will rotate the clamping carriage drive bar belt  150  which will in turn rotate the clamping carriage drive bar  148 . This action will cause the right side clamping slide carriage assembly  600  to move toward the clamping carriage home sensor  1058 . When the clamping slide carriage assembly  600  has reached the clamping carriage home sensor  1058 , the clamping carriage servomotor  150  will stop. This is the home position  62  for the clamping carriage assembly  600 . 
     The next apparatus  10  movement is the splining dispensing head assembly  200  will initialize to its y-axis home position  56  as follows: The computer control module  1004  will send a signal to the y-axis sliding carriage servomotor controller  1038  and this signal will enable the y-axis sliding carriage servomotor  190  such that the y-axis sliding carriage servomotor  190  will rotate the y-axis drive bar belt  186  which in turn will rotate the y-axis splining head drive bar  184 . This action will then cause the splining head splining head slide assembly  300  to move toward the y-axis sliding carriage home sensor  1052 . When the splining head splining head slide assembly  300  reaches the y-axis sliding carriage home sensor  1052 , the y-axis sliding carriage servomotor  190  will stop. This is the y-axis home position  56  for the splining head splining head slide assembly  300 . Next, the splining head splining head slide assembly  300  will initialize to its x-axis home position as follows: The computer control module  1004  will send a signal to the x-axis splining head servomotor controller  1036 , this will enable the x-axis splining head servomotor  330  such that the x-axis splining head servomotor  330  will rotate the x-axis splining head drive belt  338 . This action will move the splining head splining head slide assembly  300  toward the x-axis splining head home sensor  1048 . When the splining head splining head slide assembly  300  has reached the x-axis splining head home sensor  1048 , the splining head x-axis servomotor  330  will stop. This is the x-axis home position  52  for the splining head splining head slide assembly  300 . 
     The final operation in the initialization step A will be to home the rotating spline swivel rotation member  256 , this is accomplished as follows: The computer control  1004  will send a signal to the swivel servomotor controller  1034  and this will enable the swivel servomotor  242 , such that the swivel servomotor  242  will rotate the swivel head gear  250 . The swivel head gear  250  being connected to the spline swivel head rotation member  256  will rotate toward the swivel head gear home sensor  1046 . The swivel head gear  250  and the spline swivel head rotation member  256  will continue to rotate until the swivel head gear home sensor  1046  aligns with the head gear home locating hole opening  253  in the swivel head gear  250 , such that when this alignment occurs, the swivel servomotor  242  will stop. This is the home position  64  for the spline swivel head rotation member  256 . 
     STEP B. 
     Inserting the Screen Frame and Starting the Clamping Cycle Operational Process 
     The operator installs screen roll material  14  by inserting the screen material holding rods  812   a  to  812   d  through the center hole  14 R c  of the rolls  14 R of screen material  14 . The rolls  14 R of screen material  14  are then placed on to the screen tension/holder frame  802 , as shown in FIG.  16 . The operator then takes the screen material  14  and threads it through the screen tensioning slit  824  located on the screen tensioning bar  822 , as shown in FIG.  16 . The operator then places a roll  12 R of spline material  12  onto the holding bar  350  of the spline roll holder  344 . The operator then takes the spline material  12  from the spline material roll  12 R and places it through the spline hole opening  228  in the spline feed cover  212 , as shown in FIGS. 4,  25  and  26  of the drawings. 
     After the machine  10  initializes, the operator then inserts a screen frame  16  against the left and front side guides  125  and  126 , respectively, of the L-shaped guide brace  129 , as shown in FIG.  22 . The operator then presses the touch screen display  1082  for initiating the “Clamp Start Button”. The machine  10  will start the clamping cycle the screen frame  16  as follows: The computer control module  1002  will send a signal to the front finger clamp solid state relay  1020 . This will enable the front finger clamp solenoid valve  1146 , which will supply compressed air  1130  to the front finger clamp air cylinder  1116  which will push on pivot bar  444 , rotating the front side clamping shaft  408  which will push on the clamping finger heads  430   a  to  430   e  of the formed finger clamp collars  434   a  to  434   e , as shown in FIG.  22 . This action has the clamping finger heads  430   a  to  430   e  clamping the interior front perimeter side edge  24  of the screen frame  16  against the front side guide  126  of the L-shaped guide brace  129 . 
     The computer control module  1002  will next send a signal to the left finger frame clamp solid state relay  1018  and this will enable the left finger frame clamp solenoid valve  1144 , which will then supply compressed air  1130  to the left finger frame clamp air cylinder  1114 . The left finger frame clamp air cylinder  1114  will then push on pivot bar  544 , rotating the left side shaft  508  which will push on the clamping finger heads  530  and  530   b  of the formed finger clamp collars  534   a  and  534   b , as shown in FIG.  22 . This action has the clamping finger heads  530   a  and  530   b  clamping the interior left perimeter side edge  26  of the screen frame  16  against the left side guide  125  of the L-shaped guide brace  129 . 
     Next, the computer control module  1002  will send a signal to the rear frame clamp servomotor controller  1044 , enabling the rear frame clamp servomotor  170 . The rear frame clamp servomotor  170  will then rotate the rear frame clamping slide drive bar belt  166  which will then rotate the rear frame clamping slide drive bar  164 , thereby moving the rear side frame clamping assembly  700  towards the interior rear perimeter side edge  28  of the screen frame  16 . The rear side frame clamp assembly  700  will continue to move until the y-axis frame sizing sensor block  708  contacts the exterior perimeter side edge  28  of the screen frame  16 . Upon this contact, the rear frame clamp assembly  700  will advance slightly further until the rear frame clamping finger heads  704   a  to  704   d  are on the interior rear perimeter side edge  28  of the screen frame  16 . Next, the direction of the rear frame clamping slide servomotor  17  is reversed, thereby reversing the direction of the rear side frame clamp assembly  700 . The rear frame clamping slide sub-assembly  160  will move a preset distance in this direction as to position the rear frame clamping finger heads  704   a  to  704   d  in contact with the interior perimeter side edge  28 . Upon the completion of this operational step, a signal is sent from the computer control module  1002  to the rear frame clamp solid state relay  1024 , which will enable the rear frame clamp solenoid valve  1150 , thereby supplying the rear frame clamp air cylinders  1120   a  and  1120   b  with compressed inwardly air  1130 . The rear frame clamp air cylinders  1120   a  and  1120   b  will move the push rods  712   b  and  712   c , respectively, thereby moving the rear frame clamping member  720  inwardly against the outer exterior rear perimeter side edge  28  of the screen frame  16 , which completes the rear frame clamping sequence. 
     Next, the computer control module  1002  will send a signal to the clamping carriage servomotor controller  1042 , enabling the clamping carriage servomotor  154 . The clamping carriage servomotor  154  will rotate the clamping carriage drive bar belt  150 , thereby rotating the clamping bar carriage drive bar  148  of the clamping carriage sub-assembly  140 , thus causing the right side clamping slide carriage assembly  600  to move towards the interior right side edge  26  of the screen frame  16 . The right side clamping slide carriage assembly  600  will continue to move in this direction until the first upper clamping finger head  642  of the rear right clamping finger support member  652 , as shown in FIGS. 12 and 12A of the drawings, contacts the outer/exterior right perimeter side edge  22  of the screen frame  16 . Upon this contact, the first upper clamping finger head  642  will pivot and contact the x-axis frame sizing sensor  1062 . Upon this contact, the right side clamping slide carriage assembly  600  will be advanced further until the first upper clamping finger head  642  and the second upper clamping finger head  672  are position on the interior right perimeter side edge  22  of the screen frame  16 . At this point, as signal is sent from the computer control module  1002  to the right finger clamping finger solid state relay  1022  which will enable the right finger clamp solenoid valve  1148 , thereby supplying compressed air  1130  to the right finger clamp air cylinder  1118 . This pneumatic action will then pivot the second upper clamping finger head  672  into the clamping position and the direction of the clamping carriage servomotor  154  is reversed which allows the right side clamping slide carriage assembly  600  to be moved toward the interior right perimeter side edge  22  of the screen frame  16 , until the first upper clamping finger head  642  and the second upper clamping finger head  672  are in contact with the interior right side edge  22  of screen frame  16 , as depicted in FIGS. 22,  24  and  25  of the drawings. The operator then pulls the screen material  14  across the screen frame  16  via the screen tensioning bar  822 , this then completes the clamping cycle operational step B. 
     Next, the operator then presses the “Cycle Start Button” on the touch screen display  1082  to start the splining process cycle. The computer control module  1002  will send a signal to the x-axis splining head servomotor controller  1036  and the y-axis splining head servomotor controller  1038 , which will enable the x-axis splining head servomotor  330  and the y-axis sliding carriage servomotor  190  simultaneously, which will then move the spline dispensing head assembly  200  to the start position  46  on the first corner  32  and on side  22  of the screen frame  16 , as shown in FIG. 25 of the drawings. 
     Next, the computer control module  1002  will enable the dispensing head slide solid state relay  1016  which will enable the dispensing head slide solenoid valve  1142  and this will supply compressed air  1130  to the dispensing head slide air cylinder  1112 , thereby lowering the spline dispensing head assembly  200  and placing the spline material  12  and the splining wheel  258  into the screen retaining groove/channel  18  located on the perimeter right side  22  of the screen frame  16 , as shown in FIGS. 23,  25  and  26  of the drawings. 
     If the side width  22 / 26  of the screen frame  16  is of such dimension that the perimeter side rail  22  of the screen frame  16  is in line with the clamping finger heads  430   a  to  430   e  and  704   a  to  704   d  on the front clamping frame assembly  400  and the rear side frame assembly  700 , respectively. The clamping finger heads  430   a  to  430   e  and  704   a  to  704   d  will pivot under the side rail  22  of screen frame  16 , thereby preventing the clamping finger heads  430   a  to  430   e  and  704   a  to  704   d , respectively, from lifting the screen frame  16  off of the upper table surface  106  of splining tabletop  104  when the clamping cycle had commenced. 
     STEP C. 
     Spline Processing Cycle for the Right Side of Screen Frame 
     In the next processing action, a signal is sent from the computer control module  1002  to the spline guide solid state relay  1010  and this will enable the spline guide plate solenoid valve  1136  to supply compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guide plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent from the computer control module  1002  to the y-axis servomotor  190  which moves the spline dispensing head assembly  200  along the right perimeter side edge  22  of the screen frame  16 . Simultaneously, a signal is sent from the computer control module  1004  to the screen cutter frame solid state relay  1006  which will enable the screen cutter frame solenoid valve  1132  to supply compressed air  1130  to the screen cutter frame air cylinder  1102 , thereby pivoting the screen cutting wheel  282  into the screen retaining groove  18  within the screen frame  16 . This will cut the screen material  14  within the screen retaining groove  18  in the screen frame  16  as the spline dispensing head assembly  200  is traveling towards the second corner  34 . When the spline dispensing head assembly  200  reaches the second corner  34  of the screen frame  16 , the y-axis sliding carriage servomotor  190  is stopped. After the y-axis sliding carriage servomotor  190  is stopped, the spline guide plate solenoid valve  1136  is disabled, thereby reversing the air flow of compressed air  1130  on the spline guide plate air cylinder  1106  which causes the spline head guide plates  260   a  and  260   b  to lower and contact the screen frame  16 . Then a signal is sent to the corner height solid state relay  1014  from the computer control module  1002  which will then enable the corner height solenoid valve  1140  to supply compressed air  1130  to the corner height air cylinder  1110 , thereby raising the spline dispensing head assembly  200  to a secondary or corner height position  48 . Simultaneously, the screen cutter frame solenoid valve  1132  is disabled, thereby pivoting the screen cutter wheel  282  out of the screen retaining groove  18  of screen frame  16 . 
     Next, a signal is sent from computer control module  1002  to enable the spline guide plate solenoid valve  1136  which will change the air flow direction of compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guide plates  260   a  and  260   b . Next, a signal is sent to the swivel servomotor controller  1034  from computer control module  1004  which will enable the swivel servomotor  242  to rotate the swivel head gear  250  which is connected to the spline swivel head rotation member  256 , causing it to rotate 90 degrees. Next, the spline guide plate solenoid valve  1136  is disabled causing the air flow of compressed air  1130  to be reversed to the spline guide plate air cylinder  1106  thereby lowering the spline head guide plates  260   a  and  260   b  Simultaneously, the corner height solenoid valve  1140  is disabled thereby reversing the flow of compressed air  1130  to the corner height air cylinder  1110  causing the spline dispensing head assembly  200  to lower. This action will again insert the spline material  12  and the splining wheel  258  into the screen retaining channel  18  along the front perimeter side edge  24  of the screen frame  16 . 
     STEP D. 
     Spline Processing Cycle For the Front Side of Screen Frame 
     Next, a signal is sent from the computer control module  1002  to the spline guide plate solid state relay  1010  and this will enable the spline guide plate solenoid valve  1136  to supply compressed air  1130  to the spline guide plate air cylinder  1106  thereby raising the spline head guide plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent to the x-axis splining head servomotor  330  from the computer control module  1104  which moves the spline dispensing head assembly  200  along the front perimeter side edge  24  of the screen frame  16 . Simultaneously, a signal is sent to the screen cutter frame solid state relay  1006  from the computer control module  1002  which will enable the screen cutter frame solenoid valve  1132  to supply compressed air  1130  to the screen cutter frame air cylinder  1102 , thereby pivoting the screen cutting wheel  282  into the screen retaining groove  18  within the screen frame  16 . This pneumatic action will then cut the screen material  14  within the screen frame  16  as the spline dispensing head assembly  200  is traveling towards the third corner  36 . When the spline dispensing head assembly  200  reaches the third corner  36  of the screen frame  16 , the x-axis splining head servomotor  330  is stopped. After the x-axis splining head servomotor  330  is stopped, the spline guide plate solenoid valve  1136  is disabled thereby reversing the air flow direction of the compressed air  1130  to the spline guide plate air cylinder  1106 . This pneumatic action causes the spline head guide plates  260   a  and  260   b  to lower and contact the screen frame  16 . Then a signal is sent to the corner height solid state relay  1014  which will enable the corner height solenoid valve  1140  which will then supply compressed air  1130  to the corner height air cylinder  1110 . This then raises the spline dispensing head assembly  200  to a secondary or corner height position  48 . Simultaneously, the screen cutter frame solenoid valve  1132  is disabled, thereby pivoting the screen cutter wheel  282  out of the screen retaining groove  18  of screen frame  16 . 
     Next, a signal is sent to enable the spline guide plate solenoid valve  1136  from the computer control module  1002  which will change the air flow direction of the compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guide plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent to the swivel servomotor controller  1034  from computer control module  1004  which will enable the swivel servomotor  242  to rotate the swivel head gear  250  which is connected to the spline swivel head rotation member  256 , causing it to rotate 90 degrees. Next, the spline guide plate solenoid valve  1136  is disabled causing the air flow direction of the compressed air  1130  to be reversed to the spline guide air cylinder  1106  thereby lowering the spline head guide plates  260   a  and  260   b  onto the screen frame  16 . Simultaneously, the corner height solenoid valve  1140  is disabled thereby reversing the air flow direction of compressed air  1130  to the corner height air cylinder  1110  causing the spline dispensing head assembly  200  to lower. This action will again insert the spline material  12  and the splining wheel  258  into the screen retaining groove  18  along the left perimeter side edge  26  of the screen frame  16 , as depicted in FIGS. 22,  23 ,  26  and  27  of the drawings. 
     STEP E. 
     Spline Processing Cycle for the Left Side of Screen Frame 
     Next, a signal is sent from the computer control module  1002  to the spline guide plate solid state relay  101  and this will enable the spline guide plate solenoid valve  1136  to supply compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guide plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent to the y-axis sliding carriage servomotor  190  which moves the spline dispensing head assembly  200  along the left perimeter side  26  of the screen frame  16 . Simultaneously, a signal is sent to the screen cutter frame solid state relay  1006  which will enable the screen cutter frame solenoid valve  1132  to supply compressed air  1130  to the screen cutter frame air cylinder  1102 , thereby pivoting the screen cutting wheel  282  into the screen retaining groove  18  in within the screen frame  16 . This pneumatic action will then cut the screen material  16  within the screen frame  16  as the spline dispensing head assembly  200  is traveling towards the fourth corner  38 . When the spline dispensing head assembly  200  reaches the fourth corner  38  of the screen frame  16 , the y-axis sliding carriage servomotor  190  is stopped. After the y-axis sliding carriage servomotor  190  is stopped, the spline guide plate solenoid valve  1136  is disabled thereby reversing the air flow direction of the compressed air  1130  to the spline guide plate air cylinder  1106 . This pneumatic action causes the spline head guide plates  260   a  and  260   b  to lower and contact the screen frame  16 . Then a signal is sent to the corner height solid state relay  1014  which will then enable the corner height solenoid valve  1140  which will then supply compressed air  1130  to the corner height air cylinder  1110 . Thereby raising the spline dispensing head assembly  200  to a secondary or corner height position  48 . Simultaneously, the screen cutter frame solenoid valve  1132  is disabled thereby pivoting the screen cutter wheel  282  out of the screen retaining groove  18  of screen frame  16 . 
     Next, a signal is sent to enable the spline guide plate solenoid valve  1136  from the computer control module  1004  which will change the air flow direction of the compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guides plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent to the swivel servomotor controller  1034  from computer control module  1002  which will enable the swivel servomotor  242  to rotate the swivel head gear  250  which is connected to the spline swivel head rotation member  256 , causing it to rotate 90 degrees. Next, the spline guide plate solenoid valve  1136  is disabled causing the air flow direction of the compressed air  1130  to be reversed to the spline guide plate air cylinder  1106  thereby lowering the spline head guide plates  260   a  and  260   b  onto the screen frame  16 . Simultaneously, the corner height solenoid valve  1140  is disabled thereby reversing the air flow direction of compressed air  1130  to the corner height air cylinder  1110  causing the spline dispensing head assembly  200  to lower. This action will again insert the spline material  12  and the splining wheel  258  into the screen retaining groove  18  along the rear perimeter side edge  28  of the screen frame  16 . 
     STEP F. 
     Spline Processing Cycle for the Rear Side of Screen Frame 
     Next, a signal is sent from the computer control module  1002  to the spline guide plate solid state relay  1010  and this will enable the spline guide plate solenoid valve  1136  to supply compressed air  1130  to the spline guide plate air cylinder  1106 , thereby raising the spline head guide plates  260   a  and  260   b  off of the screen frame  16 . Next, a signal is sent to the x-axis splining head servomotor  330  from the computer control module  1002  which moves the spline dispensing head assembly  200  along the rear perimeter side  28  of the screen frame  16 . Simultaneously, a signal is sent to the screen cutter frame solid state relay  1006  from the computer control module  1002  which will enable the screen cutter frame solenoid valve  1132  to supply compressed air  1130  to the screen cutter frame air cylinder  1102 , thereby pivoting the screen cutting wheel  282  into the screen retaining groove  18  within the screen frame  16 . This pneumatic action will then cut the screen material  14  within the screen frame  16  as the spline dispensing head assembly  200  is traveling towards the first corner  32 . When the spline dispensing head assembly  200  reaches a preset distance from the first corner  32  a signal is sent to the spline cutter solid state relay  1008  which will enable the spline cutter solenoid valve  1134 . This pneumatic action will supply compressed air  1130  to the spline cutter air cylinder  1104 . This action will then push the spline cutter knife/blade  230  through the spline material  12  thereby cutting it. The spline dispensing head assembly  200  continues to travel towards the first corner  32  inserting the spline material  12  and the screen material  14  into the screen retaining groove  18  of screen frame  16 . When the spline dispensing head assembly  200  reaches the first corner  32 , a signal is sent from the computer control module  1004  disabling the dispensing head slide solenoid valve  1142 . This will change the air flow direction of the compressed air  1130  going to the dispensing head slide air cylinder  1112 . This will raise the spline dispensing head assembly  200  to its full raised position  50 . Simultaneously, a signal is sent to the screen roll cutter solid state relay  1026  from the computer control module  1002  which will enable the screen roll cutter solenoid valve  1152 , to supply compressed air  1130  to the rodless air cylinder  1122 . This will move the screen roll cutter assembly  900  and its associated screen roll cutting wheel  910  across the screen material  14  in which to cut the screen material  14  from the screen roll  14 R. Next, a signal is sent to the swivel servomotor controller  1034  which will enable the swivel servomotor  242  to rotate the swivel head gear  250  which is connected to the spline swivel head rotation member  256 , causing it to rotate back to the home position  64 . 
     STEP G. 
     Unclamping The Screen Frame Procedure 
     The following unclamping actions occur simultaneously. The front finger clamp solid state relay  1020 , causes the front frame clamp solenoid valve  1146 , to reverse the air flow direction of the compressed air  1130  to the front frame clamp air cylinder  1116 , thereby rotating the front side clamping shaft  408  which will move the clamping finger heads  430   a  to  430   e  away from interior front perimeter side edge  24  of the screen frame  16 . The left frame clamp solid state relay  1018 , causes the left finger clamp solenoid valve  1144 , to reverse the air flow direction of the compressed air  1130  to the left finger clamp air cylinder  1114 , thereby rotating the left side clamping shaft  508  which will move the clamping finger heads  530   a  and  530   b  away from interior left perimeter side edge  26  of the screen frame  16 . The rear frame clamp solid state relay  1024 , causes the rear frame clamp solenoid valve  1150 , to reverse the air flow direction of the compressed air  1130  to the rear frame clamp air cylinders  1120   a  and  1120   b , thereby moving the rear frame clamping member  720  away from the exterior rear perimeter side edge  28  of the screen frame  16 . The right finger clamp solid state relay  1022 , causes the right finger clamp solenoid valve  1148 , to reverse the air flow direction of the compressed air  1130  to the right finger clamp air cylinder  1118 , thereby pivoting the upper first clamping finger head  642  away from interior right side edge  22  of the screen frame  16 . The operator then manually removes the completed screen frame  20  from the machine  10 . 
     STEP H. 
     Reset for the Next Screen Frame 
     If the next window screen frame  16  is the same size as the previously screened and splined window screen frame  16 , the clamping assemblies  400 ,  500 ,  600  and  700  remain in their present position. The new window screen frame  16  is simply reclamped and the screening and splining cycle process restarted at the starting corner position  46 . If the next screen window frame  16  is a different size that the previously screened frame  16 , then the spline dispensing head assembly  200  will be initialized back to its home position  30  as previously described. The splining head slide assembly  300 , the rear frame clamp assembly  700  and the clamping carriage assembly  600  are returned to their home positions as previously described in the initialization procedure.
