Abstract
A preformed part (20) used for the production of tubular parts with a longitudinal seam is bent parallel to the direction of the axis of the tube to be produced from the preformed part (20), the two seam-forming longitudinal edges (2, 3) of the preformed part (20) being at a distance from one another which permits the accommodation of a further preformed part (20). The preformed part (20) can be closed to form a tube piece. In order to take account of the different bending moments and the forces arising from the seaming operation, the preformed part (1) is prebent or edged to a lesser extent between the longitudinal edges (2, 3) than in the region of its longitudinal edges (2, 3). <IMAGE>
