Abstract

After a predetermined number of cut forms is deposited on a conveyor, flow of forms to a stacker is temporarily interrupted by means that permit incoming forms, without interruption, to continue to shingle onto the conveyor while the stacker is being emptied.

Cut Forms Interruptor

After a predetermined number of cut forms is deposited on a conveyor, flow of forms to a stacker is temporarily interrupted by means that permit incoming forms, without interruption, to continue to shingle onto the conveyor while the stacker is being emptied.

Single or multiply web 1 is fed through continuously rotating cutoff rolls 2 and cut into discrete forms 3. These forms are shingled onto continuously moving, transversely spaced endless belts 4 and normally delivered to stacker 5, without interruption, via a throat 6 provided between upper and lower clamps 7,8 of a movable carriage unit 9. Belts 10, disposed between belts 4, are driven by respective pulleys 11 around respective idlers 12,13,14 at a constant speed higher than that of belts 4. Idlers 12,13 are rotatably supported on unit 9. Idlers 14 are supported on a shaft that is carried in a housing, not shown, that normally is positioned as shown in solid lines but can be elevated to the position shown in broken lines.

When a predetermined number of forms have been cut off, an electrical signal is suitably generated to cause the clamps 7,5 to move relatively toward each other into clamping contact with belts 4. This closes throat 6, clamps the leading form of the following group against the belts 4, and clamps unit 9 to the belts. Unit 9 now moves leftward with belts 4, thus permitting the following group of forms to shingle on the upstream runs of the belts smoothly and without dis...
