Abstract

An inertial cam surface activates a rotating registration stop to register material of predetermined length onto a rotating drum. Feed rolls 1 and 2 successively feed film chips 3 or the like into edgewise contact with one of a plurality of retractable registration stops 4. Each stop 4 is associated with a pad 5 that is mounted about the periphery of rotating drum 6. The latter carries the mounted chip past gravure roll 7 to drum 8. Roll 7 applies adhesive to selected areas of a chip 3 so it can be adhered to a copy card, not shown, that is being carried to film-mounting position by and on drum 8.

Intermittently Actuated Registration Stop

An inertial cam surface activates a rotating registration stop to register material of predetermined length onto a rotating drum. Feed rolls 1 and 2 successively feed film chips 3 or the like into edgewise contact with one of a plurality of retractable registration stops 4. Each stop 4 is associated with a pad 5 that is mounted about the periphery of rotating drum 6. The latter carries the mounted chip past gravure roll 7 to drum 8. Roll 7 applies adhesive to selected areas of a chip 3 so it can be adhered to a copy card, not shown, that is being carried to film-mounting position by and on drum 8.

Associated with each pad 5 is a roller 9 that is carried at one end of arm 10 that is pivoted at point 11. Each roller 9 serves as a cam follower for periodically engaging a single inertial cam surface 12 on film insertion unit 13. Each roller 9 maintains the center of mass below point 11 so that centrifugal force, preferably assisted by spring 14, normally keeps stops 4 retracted below the exterior of pads 5. However, just before a chip 3 is fed onto drum 6, each follower 9 periodically engages cam surface 12 and pivots arm 10 clockwise about 11 to extend the stop so it accurately registers the leading edge of the chip.

Once registered, chip 3 is held in place by vacuum which acts through holes 16 in drum 6. Surf ace 12 is configured to assure that the stop is not maintained extended any longer than necessary. Promptly after re...
