摘要: The invention concerns a method and apparatus for production of a hollow section (1) in which a coiled pre-shape of the hollow section (1) is deep drawn from a sheet part, which is pre-bent after a trimming process and coiled into the final shape of hollow section (1). The edges (45) of hollow section (1) lying in the peripheral direction are then joined together in the contact region. In order to improve the joining capability of hollow section (1) to other components in simple fashion, it is proposed that before the coiling process at least one flat site (35) for joining to another component be embossed before the coiling process in a pre-bent region of the hollow section (1).
