Claims

[Scope of utility model registration request]

A plurality of reversing claws arranged in parallel on a claw shaft on the outer periphery of the reversing cylinder,
A suction lever that is close to and parallel to the claw shaft is equipped with a plurality of suction levers arranged in parallel with the reversing claw in phase with the reversing claw on the lever shaft, and the end of the paper sucked by the suction lever is transferred to the reversing claw. In a paper reversing device for a sheet-fed rotary printing press that reverses paper by holding it in its mouth and conveying it, a suction port is formed on the suction lever shaft with a narrow width in the vertical direction of the paper so as not to interfere with the reversing claw. An auxiliary suction lever is provided in substantially the same phase in the axial direction as the reversing claw, and an air suction hole in the suction port of at least the auxiliary suction lever of some of the auxiliary suction levers located at both ends in the paper width direction and the existing suction lever is provided. A paper reversing device for a sheet-fed rotary printing press, characterized in that the opening is opened only in approximately half of the center of the paper in the width direction of the paper.
