摘要

Method and machine for forming pipes by forming rollers distributed in successive processing stations and essentially parallel to the central line and the edges of the strip, characterized in that in each station the strip is grasped between pairs of rollers substantially flat and lying in planes essentially normal to the strip, at the point of contact, each pair being formed by an external roller relatively closer to the edge of the strip and by an internal roller relatively closer to the center line thereof, and being the inclination of a roller of any station greater than the inclination of the corresponding roller of the preceding station.
