摘要 |
A method of cutting a flat tube (6) into unit pieces, which includes moving in a transverse direction rotatable disc cutters (12) with knife edges so as to cut the upper and lower walls of a flat tube to form a pair of cutting grooves (15) and fixing the flat tube at a point upstream of the cutting groove while flexing in the vertical direction a length of the flat tube downstream of the cutting grooves to break it off at the cutting grooves, thereby providing a unit piece of a predetermined length.
