ABSTRACT:
In a adapted folder for folding sheet products there is provided a combination having two knife cylinders with shear action knives of which one has pins adjacent to its knives for holding cut off trimmings of product, and a suction duct whose opening extends around part of the periphery of the cylinder with the pins. A high degree of operational reliability may be achieved without weakening the structure of the pin cylinder if compressed air nozzles are arranged in a row alternating with the pins and supplied with compressed air by timing means so that air flows from the nozzles when they register with the suction duct opening.
