Device for producing pipes corrugated at right angles to their cross-section

摘要

The device has a metal band longitudinally-inserted to a slot pipe in a molding unit (1), and a slot welded in a welding unit (2) for receiving a closed tube (3). The closed tube is provided with a corrugation in a corrugator unit (6), and an extractor device (AV) comprises two clamping jaws (4, 5) that are reciprocated in a longitudinal direction of the tube between an initial position and an end position. A holding device (7) is provided with two clamping members, where the clamping members are arranged diametrically opposite to each other and rest in working position of the tube. The tube is designed as a hollow structure for transporting fluid mediums or an electromagnetic waveguide.
