摘要
The preparation of the edge of a steel plate for the production of a steel tube by bending into a U shape and into an O shape and by subsequent expansion to centre the tube is performed by bending the steel plate in the longitudinal direction at the longitudinal edges followed by bending into a U shape in the course of the tube production process, a pressure force being used to bend the edges, which are, in particular, those of a thick steel plate, and the area of application being extended to the production of a thick steel tube without the formation of sharp burrs on the seam.
