Abstract

PURPOSE: To achieve the improvement in the adhesion of the seamed part and the improvement in workability by fitting the top and bottom plate flanges of the specified size to barrel flange and curling and seaming these flange parts by the device provided with seaming dies, etc. of the specified size sand shape by the specified method.
CONSTITUTION: A barrel flange 4A is fitted with top and bottom plate flanges 3A, 5A suitably longer than this and these are set in the device provided with a seam die 2A (having the die surface of bore 5W6t with respect to plate thickness t, depth 1M of straight line part; 1.5W2.5t, radius RA 2.5W3t), etc. and are rotated, whereby the 1st curl 13 by 180° bending containing the sealing agent 22 injected to around the flange end part is formed, thence the die is replaced with the sean die 2B of the specific size and shape and further the 2nd curl similarly containing the sealing agent 23 is formed. In this way, the bond part of the top and bottom plates 3, 5 and barrel 4 is improved of holding power, impact resistance, etc.
