Abstract

PURPOSE: To prevent cracking and make the work smooth by beforehand cutting off excess adhesive tapes by the protruding amount at the flange forming and notching the four corners of a can barrel material.
CONSTITUTION: Notching in the body forming machine is accomplished by providing the cut parts 27 parallel to the top and bottom long edges at both corner parts on one side (the side where there are no adhesive tapes) of a metal plate 1 and cutting said parts obliquely to the top and bottom long edge side. In the both corner parts on the other side (the adhesive tape side) of the metal plate 1, notches 29 (the same length as parallel cut parts 27l2) on the same straight line as the parallel cut parts 27 and angle parts 30 are cut aslant. The aslant cutting width is made slightly wider than the width of the adhesive tape. In addition, the cut-off length h of the short edge side is based on the protruding amount in flanging. Since the width of notching is made wider than the adhesive tape width, the end edges of the adhesive tapes, even when protruding out, are completely cut off at the time of notching.
