ABSTRACT:
A folder for a web-fed rotary printing press includes a cooperating pair of collection and cutting cylinders to sever a paper web into web segments. A belt conveyor system enwraps a portion of the surface of the collection cylinder just before an intake point of the paper ribbon between the collection cylinder and the cutting cylinder. This belt conveyor system prevents the newly created leading edge of the paper ribbon from springing back.
