Abstract: 1,239,379. Card laminating machine. ITEK CORP. 6 June, 1969, No. 28848/69. Heading B5N. [Also in Division B8] In a card laminating machine, a card is fed successively to a punching mechanism and to a cover-applying mechanism by continuouslymoving conveying means; stops 15, 16 (Fig. 1, not shown) engage the card at each station while the conveyer continues to move, and timing means operate synchronously with the feeding means to periodically withdraw the stops, thus allowing a card to be successively stopped for punching and cover-application. The cover sheet is supplied as a continuous temperatureactivatable adhesive coated web and the applying mechanism severs the web and applies the severed portion to the apertured card. The engagement of stops 15, 16 by the cards causes actuation of switches 14, 17 (Fig. 1, not shown) which control the punch and web-applicator. The cards are conveyed by rollers 18-23 which are driven from shaft 25 by pulleys and belts (Fig. 3, not shown). Drive system (Fig. 9).-A motor 62 drives a jack-shaft 66 which is coupled via clutches 75, 76, 77 to the input shafts 88, 96, 108 and 113 of, respectively, the sheet cutting and applying unit 79, the punching unit 80, the card feeding unit 81 and a timer mechanism 82, and to the input shaft 124 (see Fig. 10) of the web feed mechanism and the input shaft 25 of the conveyer drive. Clutch 77 controls both the card feed unit and the timer mechanism and the rotation of the web feed input shaft 124 is normally prevented by a clutch 126. Card feed unit (see Fig. 10).-Cards in a feed hopper 10 are forwarded by a reciprocable member 146 which engages the lowermost card of the stack. The member 146 is attached to a slidable block 148 having a connection via a pivoted lever 150 and a block 154, slidable in a slot 153, to the shaft 108, whereby each oscillation of the lever 150 reciprocates the member 146, on rotation of the shaft 108. Solenoidcontrolled rods 161 can be actuated to raise the stack and prevent feeding of cards. A card receiving hopper 13 is pivotable at 165A (on actuation of a solenoid) to obtain access thereto. Punch unit.-On engaging the stop 15, the card rests over a die-plate 171 having an opening for a punch 172 (see Fig. 5, not shown) which is mounted for vertical movement. The connection to the input shaft 96 is identical to that to the input shaft 88 of the web cutting and applying mechanism, and both connections are here described with reference to Fig. 6, the reference numerals of which are given in parentheses; the other numerals refer to Fig. 5, not shown. The input shaft 96 (88) mounts a cam hub 202 (286) which engages a cam roller 199 (284) attached via a guide block 195 (282) to a rod 194 (279), which is thus vertically reciprocated on rotation of the input shaft. This motion is transmitted to the punch via a lever 187 (274) and a rod 180 (270). The shaft 96 (88) mounts cams 218 (287, 288) which operate switches 217, 219 (289, 290) to ensure one operation per rotation of the shaft. Web feed unit (Figs. 6, 17).-The cover web is unrolled from a reel 220 and passes over an arcuate surface 226 and between rollers 232, 233, which are urged together by a spring 245. The roller 232 can be retracted by a lever 250 for initially feeding the web. These rollers are driven from the shaft 124 via an output shaft 235 which is normally prevented from rotating by a solenoid-controlled clutch 126. The solenoid is energized to retract a stop 238 against the action of a spring 242 so that the shaft 235 can rotate, whereby a crank 254 oscillates an arm 260 between the limits shown in Figs. 17, 18 (Fig. 18, not shown). A shaft 261 provides the input to a one-way clutch 127 which converts the oscillation of arm 260 to intermittent one-way motion for advancement of the web by a certain amount. The output shaft of the clutch 127 drives the rollers 232, 233 via gears and pulleys (Fig. 8, not shown). Web cutting unit (Fig. 6).-This is actuated by the card engaging the stop 16 which controls the switch 17. The web is severed and bonded to the card by a knife 265 and a heated platen 267, which are operated once per revolution of the shaft 88 as described under "Punch Unit". A plate 269 prevents buckling of the web during this operation. To avoid sticking of the web at the severed end, the shaft 88 rotates with a disc 293 mounting a dog 294 which can engage a roller 296 to cause a pivoted lever 297 to engage a pin 300 on the web support 226 which thus slides forward against the action of springs 302. Timer mechanism.-Four cams 324, 328, 332, 336 (Fig. 10) are driven from the shaft 113 to ensure correct sequencing of the various operations. The system is controlled by an electrical circuit (Fig. 23, not shown) which controls the operations via relays and switches.
