Abstract

PURPOSE: To eliminate the need for secondary operations such as cutting tool exchanging, chip disposal, etc., by forming a desired butting shape with rolls pressed against both edge pars of strip, after a strip is heated previously to make the rolling of its both edge parts possible.
CONSTITUTION: A strip 2 uncoiled from a pay-off reel 1 by a feeder 3 is regulated by a side guide 4 at its both sides and is sent to a heater 5 to be heated until the rolling of both edge parts of it is possible. A desired butting face is formed at the both edge parts of the heated strip 2 by the mill rolls of a butting-shape forming machine 6. This strip 2 is formed into a cylindrical shape by a group of pipe forming rolls 11 and is sent to a welder 13 to weld its butting part.
