<p>A suction unit in a sheet-fed rotary printing press includes a plurality of suction wheels (45A to 45E), a plurality of supports (24), a drive shaft (20), a motor (21), a shaft (19,42), a coupling (23), a bearing, a sleeve, and a gear, and a knob (56) and a screw (57). The suction wheels are provided below a sheet convey path to draw a sheet-like printing product into slidable contact by suction. The supports support the suction wheels to be movable in a sheet convey direction. The drive shaft, motor, shaft, coupling, bearing, sleeve, and gear drive the suction wheels in the sheet conveying direction. The knob and screw detachably fix the suction wheels to the supports. The suction wheels are connected to/disconnected from the drive shaft, motor, shaft, coupling, bearing, sleeve, and gear when the suction wheels are fixed to/released from the supports by the knob and screw. <IMAGE></p> |
