Abstract

Apparatus deforms a strip into a helically seamed pipe, with an outer and an inner bending roller and an inner pipe support on the carrier of the inner roller, acting on the pipe to size it in a plane vertical to its axis. The inner support is behind the welding point for the internal seam and is displaceable w.r.t. the carrier of the inner bending roller, vertically of the plane of the strip entering the deforming station. An inners strip loop support, as an elliptical part with its minor axis perpendicular to the pipe axis, is before the welding point, parallel to the projection, directed vertically to the plane of the entering strip of the midline of the deformed strip. Easily-distorted sheet metal can be deformed into seamed pipes of good precision.
