Abstract
The invention relates to a device and method for regulating the compressing of metal tubing (,) having inner-lying beam wave guides (,) by means of a roll straightening passage (,) comprising a feeding device (,′) of the rollers (,) with regard to the angle of wrap (A1, A2). The metal tubing (,) is unwound by a feed roller (,) in front of the roll straightening passage delivery roller (,′) after said roll straightening passage (,). According to the invention, a measuring device (,) for determining the velocity (v1, v2) of the metal tubing (,) is arranged in front of and behind each roll straightening passage (,). The measuring device (,) can determine the difference in velocity in front of and behind the roll straightening passage and the feeding device (,′) can be adjusted independently of the difference in velocity.
