SLITTER DEVICE FOR METAL STRIP MATERIAL AND METHOD OF SLITTING

摘要

PROBLEM TO BE SOLVED: To provide a slitter device capable of improving the yield of a metal strip material while remarkably lowering the generation of scrap. SOLUTION: This slitter device is provided with a cutting part 3 having an upper and a lower slit rotary blades for cutting a metal strip material 30 to be transferred from the upstream side U to the downstream side L into the predetermined width dimension so as to form plural slit material 31. An end material correcting part 4 for correcting and smoothing distortion of the end material formed by cutting the metal strip material 30 is provided at a downstream position near the cutting part 3.
