Abstract (en)
[origin: ES8603302A1] The press has a circular plate (1) rotating around a horizontal axis (2) coaxial with the longitudinal axis of the tube (12) to be formed. The plate has, on the same face, a support (3) for a spool of strip material (4). Profile forming rollers (8) form a Z or S-shaped cross-section on the strip. - A tubular mandrel (10) is mounted coaxially on the plate adjacent to its centre. Pressure rollers (11) around the mandrel ensure interlocking of the successive coils of the strip. A belt (13) assembly extracts the formed tube.
