Claims

[Claims for Utility Model Registration] (1) A pair of rotating shafts arranged parallel to each other,
A plurality of annular thick blades arranged at intervals on one of the rotation shafts, and a plurality of annular thin blades arranged at intervals on the other rotation shaft, and in a sheet slitter in which the circumferential side of the thick blades and the circumferential side of the thin blade are brought into contact with each other, (a) the plurality of thick blades are arranged such that areas with wide and narrow intervals are alternately arranged; (b) A slitter for sheet-like materials, characterized in that a pair of the plurality of thin blades is arranged in each of the regions where the thick blades are arranged at narrow intervals. (2) The sheet-like material slitter according to claim (1), wherein each of the pair of thin blades is provided with a pressing means for pressing the thin blades in a direction in which the two thin blades are mutually expanded. (3) The sheet-like material slitter according to claim (2), wherein the pressing means is a magnet provided on the side with a wider arrangement interval.
