Abstract
A sheet-like object feed unit in a sheet-fed rotary printing press includes a feedboard, paper feed belts, connecting plate, improper paper feeding detector, swing arm shaft pregripper, transfer cylinder, non-motion roller, gripper closing cam, and air cylinder. The feedboard, paper feed belts, and connecting plate convey a sheet-like object. The improper paper feeding detector is disposed on a sheet-like object convey path including the feedboard, paper feed belts, and connecting plate, and detects improper feeding of the sheet-like object. The swing arm shaft pregripper is disposed downstream of the feedboard, paper feed belts, and connecting plate in a sheet-like object convey direction, and has a first holding unit for holding the sheet-like object conveyed by the feedboard, paper feed belts, and connecting plate. The transfer cylinder is disposed downstream of the swing arm shaft pregripper in the sheet-like object convey direction, and has a second holding unit for holding the sheet-like object held by the swing arm shaft pregripper. The non-motion roller, gripper closing cam, and air cylinder disable the second holding unit when the improper paper feeding detector detects improper feeding of the sheet-like object.
