Claims

[Scope of utility model registration request]

A transfer cylinder that faces the signature conveying downstream side of the gripper cylinder, a plurality of claws that open and close in parallel on a claw shaft mounted in an outer circumferential notch of the transfer drum, and an outer end of the wall surface of the cutout. a plurality of claw stands mounted at intervals in the axial direction of the cylinder and holding signatures between the claws; and a plurality of strips stretched in such a manner that the starting end surface of the transfer cylinder faces the circumferential surface of the transfer drum. In a folding machine of a rotary printing press, which is equipped with a conveyor tape and a signature guide whose tip portion faces near the portion where the cylinder circumferential surface of the conveyor tape contacts, The end surface protruding from the barrel is formed so as to be located on the same plane as the end surface of the claw base protruding from the transfer barrel.
A plurality of signature guide members are fixed to the notch wall surface, and a groove is provided on the circumferential surface of the transfer drum to allow the tip of the signature guide to engage and retreat from interference with the signatures. A paper jam prevention device in a folding machine of a rotary printing press, characterized in that the signature guide member is provided so as to avoid a corresponding portion of the folding machine.
