The machine is used in metalworking for the manufacture of beam from strip blanks by cold bending. It produces a wide range of different type size cold bent profiles using only one set of moulding grooves of section shafts of simplified design and with no additional elements. Readjustment is fast and easy. The roller machine includes a base (1) to which stands (2) are bilaterally mounted supporting moulting grooves made of upper and lower section shafts which are resting on supports (3) mounted on the stands (2). Every upper and lower section shaft is made of at least two section rollers (4) wound onto a supporting shaft (5) with one-way thread. At least one axial first (6) and second (7) keyways are machined along the common diameter of the section rollers (4) and the supporting shaft (5) in which grooves the section rollers (4) and the supporting shafts (5) during operating position are in between fixed by keys (8).
