Abstract

A method of profiling a tube (2) of given length (L), whereby, after inserting the tube (2) between at least one pair (4) of rolls (5) having respective coplanar, parallel axes of rotation (6) crosswise to the tube (2), the rolls (5) are moved onto the tube (2) and pressed gradually against the tube (2), which, at the same time, is moved axially back and forth.
