FIELD: machine tool manufacture. SUBSTANCE: sheet blank is manually fed to guide rollers of an inlet device which center it relative to the axis of profiling. Then the sheet is gripped and fed by drive central rollers of a preliminary bending stand in which the sheet is circumferentially bent in the cross section. The sheet blank is pushed into a nondriven corrugating pulley and enters forming rollers of the first working stand which are staggered on upper and lower bases. All wave-shaped corrugations are synchronously formed on the circular bent sheet blank. The forming rollers in the last stand are located horizontally. A flat wave-shaped corrugated panel comes out of this stand and is gripped by rollers of drive profiling stands 4 where the corrugations with rounded tips are upset into corrugations of the necessary geometry. EFFECT: improved structure. 5 dwg
