摘要：1. A device for producing products with at least one transverse fold which arecut parallel to the same and are selectively delivered after the transverse fold or

provided with another, longitudinal, fold, comprising a folding unit constisting of a foldingflap cylinder (2) co-acting with a knife cylinder (4), said folding flap cylinder (2) beingfollowed by a positioning star (21) and a belt transport (23) which is selectively actedupon and which leads to a folding knife (22), characterized in that in the segments

between the folding flaps (1), the folding flap cylinder (2) is provided with a shearing knife(14) projecting beyond the circumference thereof and respectively co-acting with asecond shearing knife (16) mounted on a knife support cylinder (15) adjacent to saidfolding flap cylinder (2) and downstream of the knife cylinder (4) in the direction ofrotation, and that in the segment of the belt transport (23) which is spaced from thefolding flap cylinder by at least the amount the shearing knife (14) projects beyond thecircumference thereof, the folding flap cylinder (2) is associated with a gripper cylinder(27) incorporating controlled grippers which engage the folding flaps (1) and move overthe shearing knife (14), and in the segment of the positioning star (21) downstream of the

belt transport (23) in the direction of rotation a controlled flap (24) with lift fingers (25)which engage the folding flaps (1) and move over the shearing knife (14).
