Abstract

A tube-forming machine (10) permits the formation of tubing (14) from a flat strip of material (12) using a continuous in-line process. In this manner, tube (14) may be formed from flat strip material (12) without transferring the preformed strip from one set of former rolls to a second, third, fourth, and in some cases fifth set for further forming. The resulting tubing (14) is of a high quality and the properties of the material have been substantially preserved so that, if necessary, the output tubing (14) from the present tube-forming machine (10) may be further processed into a desired finished product.
