An embodiment of a method for profiling a tube of given length, whereby, after inserting the tube between at least one pair of rolls having respective coplanar, parallel axes of rotation crosswise to the tube, the rolls are moved onto the tube and pressed gradually against the tube, which, at the same time, is moved axially back and forth.
B21B 13/10 - Metal-rolling stands, i.e. an assembly composed of a stand frame, rolls, and accessories with differently-directed roll axes, e.g. for the so-called "universal" rolling process all axes being arranged in one plane
B21B 39/20 - Revolving, turning-over, or like manipulation of work
B21B 17/10 - Tube-rolling by rollers of which the axes are arranged essentially perpendicular to the axis of the work, e.g. "axial" tube-rolling with mandrel having one or more protrusions in a continuous process
B21C 37/20 - Making helical or similar guides in or on tubes without removing material, e.g. by drawing same over mandrels, by pushing same through dies
B21C 37/15 - Making tubes of special shapeMaking the fittings
B21D 5/12 - Bending sheet metal along straight lines, e.g. to form simple curves by drawing procedure making use of dies or forming-rollers, e.g. making profiles for making tubes making use of forming-rollers
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.
