The machine is intended for production of thick-wall pipeline fixtures for the purposes of the power, construction, chemical industries, etc. It has a simplified and lightened construction and is highly reliable. The machine includes a bearing frame (1), formed as an equilateral triangle, in the geometric centre of which is fitted a vertical bearing axis (3), at the top end of which are shafted a rotating table (4) and a bending roll (6) located above it. The rotating table (4) is actuated by a hydraulic actuating mechanism, consisting of three hydrocylinders (5), whose pistons are jointly connected with one of the peaks of the rotating table (4), formed as another isosceles triangle. The corpus of each hydrocylinder (5) is jointly connected to the respective peak of the holding frame (1). The one edge of the bending roll (6) holds a statically stitched clasping mechanism with a mobile pressing jaw (10), actuated by a fourth hydraulic cylinder (11). The holding frame (1) is statically joined to a directive (14), with a fitted to it slider (15), a bearing roll-bearer (18) with shafted to it support rolls (19), connected with a hydraulic mechanism for regulation of the position of the support rolls (19), connected with a hydraulic mechanism for regulation of the support rolls' (19) position against the bending roll (6).
