Abstract

PURPOSE: To make possible to control the horizontal moving speed of blades synchronously to the moving speed of material during cutting processes while the meterial is cut to short lengths or film sheets at high line speed.
CONSTITUTION: When a motor 15 runs, a gate frame 7 with an upper blade 8 is moved around being kept horizontally through a gear train, the upper blade 8 is moved in a circular locus, and the lower blade 11 is moved in a wavy locus being kept its direction by the gate frame 7. Therefore, the blades act perpendicularly to the material passing between the upper blade 8 and the lower blade 11, so that the horizontal moving speed of blades is controlled synchronously to the moving speed of the material, and the material is cut with high accuracy.
