Forms Creasing, Folding and Refolding Machine

This creasing, folding and refolding machine is used, e.g., in the printing, scoring, punching and processing of web type continuous documents such as, data processing cards, checks, and other types.

Generally, the methods used to fold or refold forms involve a crimping roll, a pusher type drive or a manually or automatically positioned forms guide. These methods in conjunction with the aid of gravity have been satisfactory for low speed operation. When used at higher speeds there is a tendency for misfolds to occur as a result of static and air turbulence created in and about the forms. The problem is primarily caused by not having the forms under positive control at folding time.

This machine eliminates the above problem in a mechanical transporting mechanism 1 which contains several captivating type latches 2, one for each and every crease or fold. Latches 2 hold the creases or folds under positive control until the folding is completed at 3. If a misfold occurs, the device corrects on the next fold, thus permitting continuous operation and also eliminating an accumulative type of unacceptable misfold.

The application of an air pressure differential comprising vacuum 4 and air 5 aids gravity and provides an assist in starting and completing the fold. Such occurs while the mechanical latching and transporting mechanism has it under complete control at 6. The mechanism has interchangeable captivating latches 2 and 7...
