Abstract

A folding apparatus for a rotary printing machine utilizes a plurality of belt guide systems to retain signatures against the surfaces of the collecting, folding and gripper cylinders of the folding apparatus. The position of a longitudinal folder or of a turning bar or bars can be shifted in the axial direction of the collecting cylinder at least the width of one belt to align at least one longitudinal edge of the signatures with one of the belts in the belt guide system. The grippers on the collecting cylinder will engage the leading edge of the signatures without damaging them.
