    摘要: A cylindrical helical seamed metal tube wherein the seam thereof is at an angle of between 1 and 25 degrees with respect to the axis of the tube. A method of making the tube comprises the steps of continuously feeding the metal strip into a tubing former to form the metal strip into a helical tube with the leading and trailing edges juxtaposed, the feeding such that the strip longitudinal axis is at a substantially constant acute angle with respect to the tube longitudinal axis of between 1 and 25 degrees. After the tube is substantially formed, applying pressure on at least the leading edge, leading portion, trailing edge and trailing portion in the direction of the cylindrical wall such that same substantially conform to the cylindrical wall. The juxtaposed leading and trailing edges are fused together to form a fused seam, and maintained in a juxtaposed position until the seam cools sufficiently to maintain the juxtaposed position. An apparatus for making the tube is also provided.

    摘要: In a method of manufacturing a helically-wound lock-seam tube 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 of sheet metal from a supply to a punching and pressing unit; punching and pressing the strip in the punching/pressing unit to form two rows of spaced openings through the strip; feeding the punched strip to a roller unit, in which a longitudinal bead is formed in the strip; feeding the punched and beaded strip to a forming head in which the strip is helically-wound to form a tube 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 is provided with a desired pattern of air nozzles.

    摘要: A method and apparatus for cutting spiral pipe is disclosed. The pipe cutting apparatus includes a driving mechanism that imparts rotation to a knife located inside the spiral pipe via a drive element, such as a drive shaft. The method includes forming a spiral pipe from a strip of material received at a forming head of a spiral pipe former, engaging a driving mechanism attached to a first knife positioned substantially inside the inner circumference of the pipe forming head to impart rotation to the first knife, and cutting the spiral pipe with the first knife by bringing a second knife positioned substantially outside the outer circumference of the forming head into overlapping contact with the first knife.

    摘要: A method and apparatus for forming corrugated pipe is disclosed. The pipe forming apparatus includes a selectively operable corrugation module having an inner corrugation roller movably mounted relative to an outer corrugation roller via a cylinder assembly. The method includes forming a length of spiral pipe without corrugations, engaging a corrugation module to introduce a desired length of corrugated pipe, and retracting the corrugation unit to allow a second length of uncorrugated pipe to form. The uncorrugated portion of the pipe is then severed cleanly using overlapping inner and outer cutting knives.
