Abstract
Two fixed blades are provided at substantially right angle with each other with a juncture line thereof being in the transverse direction and opposite to the terminal end of a feeding conveyor passage of a sheet material to be cut. Two movable cutter blades are also provided at substantially right angle with each other opposite to the fixed blades in such a manner that one cutter blade coacts with one fixed blade and the other cutter blade coacts with the other fixed blade to cut the sheet material at substantially right angle with respect to the plane of the sheet material. The two movable cutter blades are made to alternately advance and retreat at a predetermined timing.
