Abstract

The drawing gap is formed between the peripheries of two rollers (4,6) on parallel shafts in a common plane. The number and shape of the gaps are such that no stress is generated during formation of the flat cross-section. One roller (4) in each pair can have flanges, between which the other roller (6) protrudes part-way. The pairs of roller shafts (3,5) can be accommodated in supports (2) in a frame (1). One or more subsequent presses can also be provided, gradually converting the pipe in a flat cross-section.
