Abstract: PROBLEM TO BE SOLVED: To suppress the generation of palpus and chips when a sheet form article is cut by a shear cutter. SOLUTION: In a cutting device of sheet form article which cuts the sheet form articles running continuously, by a shear cutter consisting of plural upper blades and lower blades provided in the width direction, the positioning relation in the sheet form article width direction of the upper blades 22 and the lower blades 23 of the shear cutter which are positioned at both sides in the width direction of the sheet form article to be cut in the band form, is made in the reversal positioning relation. Consequently, the pushing in direction of the upper blade of the shear cutter can be specified in an optimum direction at both sides, and the rubbing of the cutting end surfaces each other when band form cut films are separated can be suppressed at the minimum limit.
