Zusammenfassung:	FIELD: technological processes. ^ SUBSTANCE: device contains spindle installed in casing on frictionless bearings with cylindrical radially arranged grooves, molding rollers installed on frictionless bearings provided in casing of every roller in roller-holders, which have compression springs and latch, and wedge pressing mechanism with pneumatic drive. There is also adjusting sleeve for control of rollers position. Roller-holders are installed in corresponding groove of spindle with the possibility of radial displacement and change of their angular position in relation to axis of tubular billet feed. At that molding rollers with roller-holders are arranged in the form of two three-roller profiling blocks and are installed in specified wedge pressing mechanism, and replaceable washer is installed between them. Adjusting sleeve is arranged with cylindrical gear wheel installed on it and connected with it with adjusting drive. ^ EFFECT: expansion of technological resources and increase of quality. ^ 1 dwg
