发明名称 Apparatus for straightening tubing
摘要 Uniform lengths of accurately straight metal tubing are produced from a tubing supply in the form of a multilayer helically wound coil of tubing by passing tubing from the coil through a first straightening device to approximately straighten the tubing, successively severing uniform lengths of the approximately straightened tubing from tubing discharged from the first straightening device, and throwing the severed length of tubing axially through a guide tube of a length greater than that of the severed length of tubing into the inlet of a second straightening device operable to perform a final precise straightening of the severed length of tubing.
