ABSTRACT:
Positioned adjacent to the delivery end of a device for folding sheets delivered from a printing press is a sheet pick up device to intercept a sheet for test purposes. The mechanism to intercept the sheet includes a receiving roller carrying a guide belt which is moved into the delivery path and then transfers the sheet to a second guide belt for holding the test sheet between the two guide belts for delivery to a special delivery means where the sheet can be inspected. The roller is supported on a movable arm which is synchronized with the delivery belt of the folding apparatus, and the guide belts are arranged to move at a speed faster than the delivery belts. The removal of a sheet for test purposes does not interfere with the delivery of the other sheets and operations do not have to be stopped to test a sheet.
