Abstract
729,728. Photo-electric control of web feeding. SAPAL, SOC. ANON. DES PLIEUSES AUTOMATIQUES. Dec. 31, 1953 [Jan. 8, 1953], No. 36331/53. Class 40 (3). In a device for feeding strip periodically, the strip is given a constant amplitude feed and a variable amplitude correcting movement which is imparted by a correcting apparatus having a reciprocating movement and which grips the strip at a point in the reciprocation when a datum mark on the strip is detected by a photo-electric code carried by the correcting apparatus. As shown, the constant amplitude feed is given to the strip by jaws 6 which grip the strip periodically and draw it from a drum 3 over a spring tensioned roller 4. The correcting movement is imparted to the strip by a reciprocating mechanism 8 which includes a photo-electric cell 9, light source 10, solenoid 13 and plunger 16. An eccentric 23 and bell-crank lever 24 reciprocate this mechanism on, a guide 18 and a cam 37 periodically closes a switch 34. In operation, with the jaws 6 open, the correcting mechanism 8 commences to move to the right. When a datum mark on the strip is illuminated by source 10, photo-electric cell 9 receives reflected light and energizes solenoids 13 and 30 connected in series with each other and with camoperated switch 34 now closed. Solenoid 13 presses plunger 16 into contact with the strip which it then carries backwards with the correcting head while solenoid 30 removes a gripping member 26 from the strip allowing the feed-back to be taken up by the spring-loaded jockey arm 4. When the correcting head completes its movement to the right, cam 37 opens switch 34 releasing the solenoid gripper 16 and holding the strip by solenoid actuated member 26. Jaws 6 then grip the material and a rod 33 releases member 26, the strip then being drawn to the left a fixed amount and sheared immediately afterwards. If a double strip is used the bed of the machine may be slotted, so that member 16 is able to clamp the strips together against a member which moves with the correcting head.
