Abstract
PURPOSE: To apply adequate tension to a blank material and perform stable and good welding by interposing a stepless speed change device and a clutch between a sizing zone and a forming zone for forming a strip-like blank material into a pipe shape.
CONSTITUTION: A stepless speed change device 32 and a powder clutch 33 are interposed between the driving shaft 24 of a sizing zone 13 and the drive shaft 28 of a forming zone 5 and both shafts 24, 28 are connected. For example, one of about 1/4.712 ratio is for the tripple reduction gear device 25 of, for example, a sizing zone 23, one of about 1/3.125 ratio or the tripple reduction gear device 29 of a forming zone 5, and one of about 1/3.125 for the device 32, so that the number of revolutions of the rolls 6 of the zone 5 is changed to about 0.18W1.08 range with respect to the number of revolutions of rolls 14 of the sizing zone.
