Abstract

PURPOSE: To improve productivity and to reduce equipment cost etc., by manufacturing a finished can at one effort using a working machine the same as that used for forming the can.
CONSTITUTION: A can body 1a is made primarily of disc-shaped material by drawing, then a can body 1b is formed by redrawing. In the redrawing process, a flange 2 is formed at the open end of the can body 1b at right angles to the axis. Said flange 2 is partly different in length because of the anisotropic property of the material. The can body 1b is trimmed in the trimming process so as to make the length of the flange 2 equal at all directions by pressing thereby forming a can body 1c. The trimmed flange 2' is subjected to stretching process, hereby the flange 2' is raised up to form the same face as that of the trunk of the can body 1c to obtain can body 1d, which is then subjected to necking process, where the open end of the can body 1d is worked to form a can body 1e having a neck. Finally a flange 4 is formed at the open end of the can body 1e to complete a can body 1f.
