FIELD: technological processes.
SUBSTANCE: invention is related to the field of metal plastic working, in particular to equipment for making of section bars with periodically varying corrugations. Gears installed along edges of working shaping roller are arranged to interact with gears of rotary units, which are installed at the edges of rotary axis, which interacts with hydraulic drive, and shaping cartridge is installed at eccentric section of rotary axis with the possibility to interact with driving working shaping roller. Opening of shaping rollers that roll the main section bar, is carried out due to retracting of independently rotating cartridge, which interacts with driving working shaping roller.
EFFECT: invention provides for reliable feed of initial strip and higher accuracy along length of shaped corrugation periods, reduced scope of equipment design and manufacturing.
