Slitter blade positioning mechanism

摘要

PROBLEM TO BE SOLVED: To position a cutting tool with high accuracy. A blade positioning mechanism is provided corresponding to each of a pair of holders 68 that support a first blade shaft 58 provided with a first blade 54, and the holder 68 is first placed by rotation of a feed screw. A linkage erected between a pair of arms 66, 66 and a pair of arms 66, 66 and a feed screw mechanism that linearly moves so that the amount of overlap between the blade 54 and the second blade 56 changes. The portion 84 includes a parallel link mechanism portion that moves the holder 68 so that the offset amount between the first blade 54 and the second blade 56 changes. [Selection diagram] FIG. 13
