FIELD: metal pressure forming. SUBSTANCE: apparatus includes a monolithic drawing die with round gage, a pair of vertical rollers with smooth barrel, a connectable guide with a rectangular opening and a profiling roller-type drawing die, successively mounted in the same production flow line. A distance between a rear end wall of the guide and rotation axles of rollers of the profiling roller-type drawing die is determined according to a relation, given in a description of the invention. EFFECT: enhanced efficiency and structure. 1 cl, 4 dwg
