    摘要: In a method of manufacturing a helically-wound lock-seam tube (8) for a ventilation duct system, the tube is provided with a plurality of air nozzles through its wall. The method involves the steps of: feeding a strip (1) of sheet metal from a supply (2) to a punching and pressing unit (3); punching and pressing the strip in the punching/pressing unit (3) to form two rows of spaced openings through the strip; feeding the punched strip to a roller unit (5), in which a longitudinal bead is formed in the strip; feeding the punched and beaded strip to a forming head (7) in which the strip is helically-wound to form a tube (8) having a helical lock seam; feeding the helically-wound lock-seam tube out of the forming head; and cutting the tube into desired lengths. The apparatus has components for carrying out the various method steps, and the finished tube (8) is provided with a desired pattern of air nozzles.

    摘要: La paroi tubulaire est réalisée par roulage d'une tôle dont deux bords opposés (4, 6) viennent en regard l'un de l'autre par leurs tranches et sont reliés de façon étanche par brasage. Selon l'invention, l'un (4) de ces bords présente des saillies (3) qui viennent se loger dans des évidements conjugués de l'autre bord (6) de façon à empêcher leur écartement mutuel lors du brasage.

    摘要: An automatic formation device or an automatic formation system sets an equipment operation time from a required manufacturing time per product during the manufacturing of tubes having a round, polygonal, or oblong cross-section, wherein values are calculated from a product diameter (D), and a pitch (P), a product length (L) and a preset time (T) of a metal band plate to be wound, operations of respective components are controlled on the basis of the calculated values while the respective values are being controlled, and the metal band plate is held by a chuck that is disposed on the tip side of a winding core member and rotates in a synchronized manner so as to prevent loosening of the wound metal band plate by tightening/untightening the metal band plate as needed. Also, a rotation speed correction function for a motor system is added.
