DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chopper blade for adjusting the insertion amount of a chopper blade between chopper rollers provided in a chopper folding device of a chopper folding machine that uses a web printed on an offset printing machine or the like as a signature. The present invention relates to an insertion amount adjusting device.

[0002]

2. Description of the Related Art A chopper folding machine 1 shown in FIG. 8 includes a former 3 for vertically folding a web W, a cutting cylinder 5, a plunging cylinder 7,
