Abstract (en)
[origin: EP0233377A1] A folding apparatus for a web rotary press, which folds signatures obtained by cutting a web by a combination of a cutting cylinder (6) and a pin cylinder (7), has a folding cylinder (12), a gripper cylinder (16), a speed reduction cylinder (19), and a pair of upper and lower transfer cylinders (23, 25). The folding cylinder (12) has pins (13) and insertion blades (14) on an outer surface at equal angular intervals. The pins (13) are alternately arranged with said insertion blades (14). The gripper cylinder (16) has gripper plates (17) and a diameter substantially 1/1.5 times that of said folding cylinder (12). The speed reduction cylinder (19) is rotated at a peripheral velocity lower than that of said gripper cylinder (16) and has gripper units (20). The upper and lower transfer cylinders (23, 25) are rotated at the same peripheral cylinder (19) and have gripper units (24, 26) at surface positions at equal intervals.
