Abstract

A folding mechanism adapted for cutting printed sheets from a web, includes a collecting cylinder 1 with radially movable folding blades e.g. 5, cutting grooves e.g. 11, 13 and grippers e.g. spikes 9, 11, a cutting cylinder 3 with cutting knives 17, 19, and a receiving cylinder not shown. Two sheets are collected on each gripper and transferred to the receiving cylinder. To avoid the end of the first collected sheet 21 being trimmed a second time when the second, superposed sheet 23 is cut from the web, the folding blade 5 underneath the sheets is moved radially outwards to displace the end of the first sheet away from the cutting groove 15. Contact between a projecting folding blade and the cutting cylinder is avoided by providing flats 27, 29 on the latter or by not moving the blade out until after it has passed the nip. <IMAGE>
