FIELD: construction. ^ SUBSTANCE: for the manufacture of triangular section shapes, two strips of a certain width are made; each strip is bent in two with a radius of no less than two strip widths before attaching the strips to each other. For the manufacture of quadrangular section shapes, two pairs of strips are made, each strip in each pair has a different width; the larger width strip in each pair is bent in two with a radius of no less than two strip widths. The pressure between them is created for shaping. ^ EFFECT: decreased energy consumption and labour consumption during manufacture. ^ 3 dwg
