Description

technical field

[0001] The present invention relates to a laser processing device and a container manufacturing device suitable for preventing the occurrence of resin fuzz when manufacturing a cylindrical container from a metal plate having a resin coating formed on both sides by one-time drawing. Background technique

[0002] Conventionally, as beverage cans and solid food cans, etc., drawn cans (Patent Document 1), thinned and redrawn cans (Patent Documents 2 and 3), thinned and redrawn cans (see For example, containers (seamless tanks) such as Patent Document 4). The manufacture of this container first punches a disk-shaped blank from a sheet material on which a resin coating has been formed on one or both surfaces of a metal plate, and then draws the blank to form a cylindrical primary-drawn body (hereinafter sometimes Also called "cup-shaped body"). Next, this cup is subjected to redrawing and thinning and drawing.

[0003] Such a method is mainly due to the fact tha...
