CLEARANCE DETERMINATION METHOD OF GANG EDGE CUTTING DEVICE, CUTTING METHOD BY GANG EDGE CUTTING DEVICE, AND GANG EDGE CUTTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a clearance determination method of a gang edge cutting device in which determination of a clearance amount between upper and lower edges is facilitated.

SOLUTION: In the gang edge cutting device in which the web is cut in the longitudinal direction after the press working is carried out on the metallic web on which active materials are intermittently coated are dried in a manufacturing process of an electrode for a non-aqueous electrolytic solution secondary battery, and in the method to determine the clearance C between respective opposing end faces to which respective disk-shaped upper edge 18 and lower edge 20 adjacently arranged so as to have an overlapping part in the vertical direction, the clearance between the upper edge 18 and the lower edge 20 is determined by measuring a folded amount D of a folding part 23 of a non-coating part formed in a cutting edge part of tape-shaped electrode materials 22 after cutting.
