Abstract

The slow production rates associated with cutting machines for cutting extruded metal tubing to length are avoided in an apparatus that continually cuts extruded metal tubing (46) and which include a reel (44) for providing a coil of (42) of metal tubing (46) to a cutting nip defined by rollers (66) carrying scoring knives (68). The tubing is continuously moved through the nip by a continuously operated set of feeding rolls (70) and then passed to a set of pull rolls (74) which are driven at a more rapid rate to place the tubing (46) in tension to cause it to be severed where scored. Also disclosed is a method of continuously cutting extruded metal tubing.
