PROBLEM TO BE SOLVED: To provide a perforation device for a battery packaging body which continuously and smoothly form a perforation in the axial direction of the batteries on a heat-shrinkable film sections on the front and the rear located between the batteries to a plurality of battery packages. SOLUTION: This perforation device onto battery packaging bodies is equipped with a carrying means for carrying battery packages in parallel with the axial direction of the batteries, and a perforation placing mechanism for placing a perforation on the heat-shrinkable film sections on the front and the rear located between batteries of the carried battery packages in the axial direction of the batteries. In addition, the perforation placing mechanism is equipped with a pair of pressing rollers, and a discoid cutter. In this case, for a pair of the pressing rollers, the central axis is arranged in the arranging direction of a plurality of the batteries, and a pair of the pressing rollers are made of a flexible material, and at the same time, are divided into a number equivalent to the quantity of the batteries of the battery packages in the axial direction. The discoid cutter is coaxially and rotatably fixed to the rollers between the divided pressing rollers, and has a larger diameter compared with the roller. COPYRIGHT: (C)2005,JPO&NCIPI
