Abstract: Spiral forming methods can be used to join edges of a rolled material along a spiral joint to form conical and/or cylindrical structures. Alignment of the edges of the rolled material can be controlled in a wrapping direction as the material is being joined along the spiral joint to form the structure. By controlling alignment of the edges of the material as the edges of the material are being joined, small corrections can be made over the course of forming the structure facilitating control over geometric tolerances of the resulting spiral formed structure.

Abstract: A container is produced from a single-layered, helically bent sheet metal strip. In the strip's upper or lower border region a first helically running border portion of the strip is bent out via a helically running outwardly bent edge with a curved region toward the outside of the container as a protruding flange. A second helically running border portion is in the lower/upper border region. The border regions each border one another adjacently height-wise and are connected to one another in a fluid-tight manner via a continuous, helically running welded joint. The second border portion runs rectilinearly in the plane of the strip and the welded joint has a first and a second weld seam. The first and second weld seams are applied from the outside and the inside of the container, respectively, and the two weld seams are fused to each other in the weld route thereof.

Abstract: Process and apparatus for making a flexible tube comprising a plurality of helicoidal metal members in side-by-side relation. In the process, metal strips, shaped to the desired configuration, are twisted around their longitudinal axes to helicoidal shape, the twisting being sufficient to cause the shape to be retained if the strip is released. Thereafter, the so-shaped strip is bent around an axis extending in the width direction of the strip by an amount sufficient to cause the strip to have a radius substantially equal to the tube radius. The strips are then laid up, side-by-side into a tube. The apparatus comprises a rotatable cage carrying bobbins having the strips thereon, two pairs of preshaping rollers to produce the twist and the bend mounted for rotation with the cage, a mold for laying up the helicoidal strips, a guide element for the strips intermediate the rollers and the mold and a take-up bobbin or drum for winding up the tube as it leaves the mold.

Abstract: Apparatus for forming a non-rotating helix of metal strip. The apparatus includes a store for the strip rotatable about the axis of the helix. The store has a radially inwardly facing circumferential opening from which the strip is withdrawn by guide shoes which are also rotatable about the axis of the helix but at a different rotational speed to that of the store so that the difference in diameter of the strip on leaving the store and entering the helix is accommodated. The guide shoes deliver the strip to guide rollers rotating with the guide shoes by which the strip is guided in a spiral to non-rotating helix-forming shoes from which the coils of the helix are delivered in an axial direction.

Abstract: A method and apparatus for forming a spiral tube from a length of metallic strip material wherein the strip is fed through a closed tube forming die operative to form the strip into a spirally wound tube having its longitudinal edges in juxtaposed relation. Driven torque wheels carried on one or more support carriages downstream from the forming die are operative to engage the outer peripheral surface of the tube to prevent springback and enable selective control of the relation between juxtaposed edges of the strip as it is passed longitudinally through a welding station during which the juxtaposed edges are welded to form a continuous leak-proof seam. The metallic strip may be planar or have longitudinal flutes formed therealong.

Abstract: A thin perforate, helically wound welded edge tubing is used as a filter core for a roving wound filter. The slightly roughened external edges of the spirally formed welded joint greatly adds to the ability of securing the fiber roving to the tube and prevents relative slippage therebetween. Also, the invention comprehends an apparatus for, and a method of making the helically seamed tube by first drawing a sheet metal from a supply and raising two lateral edges thereof to form flanges. The material can be guided in a helical path by engaging the inside of the flanges so that the trailing edge abuts the leading edge. The abutted edges are heated so that the flanges themselves provide the filler for a weld on the exterior surface thereof. Drive rollers are provided to move the welded tube from the welding area and to torque the tube to prevent edge separation prior to the cooling of the weld.

Abstract: A tower houses a forming mill which shapes and feeds forward a strip of metal having an upstanding male locking hook along one edge and an upstanding downwardly opening female locking strip along the other edge. A substantially semicylindrical mandrel lower part has an end secured to the tower and projects horizontally outward under the mill at an angle to the strip. The mandrel upper part has a flat plate pivotally connected to the lower part and bears a way in which a slide carrying a curved guide plate is adjustably positioned. The mandrel parts may be adjusted angularly in a horizontal plane and locked in position and the slide is linked to a turntable slide carrying a lower pinch roll which may be angularly and vertically adjusted in position. The tower carries an upper pinch roll and a bending roll for bending the strip downward. The bent strip is guided angularly and downwardly by the forward side of the mandrel lower part toward an exit conveyor for carrying away the formed pipe. As each turn of strip around the mandrel approaches the top it is angularly guided by the curved guide plate so that the male locking hook of the turn engages the female hook of the next turn and the pinch rolls clinch the hooks for continuously forming the spiral-seamed pipe.
