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:
A container (10) is produced from a spiral-shaped, bent sheet strip (20) having a first edge section (22) extending in a spiral shape, being bent, and forming a bending edge (24) extending in a spiral shape toward the inside or the outside of the container (10). The sheet strip (20) has a second edge section (32) opposite the first edge section (22) in the longitudinal direction of the sheet strip (20) and extends in a spiral shape. The second edge section (32) overlaps a third section (28) opposite the first edge section (22) in relation to the bending edge (24) and is adjacent to the bending edge (24). The second edge section (32) and the third section (28) are welded to each other in the region of the overlap (30). The welding seam (40) extends at least partially into the region between the second edge section (32) and the third section (28) of the sheet strip (20).

Abstract:
A system for storage of green fodder and the like includes a cylindrical storage tank removably carried on a trailer which can be towed by a tractor. The frame of the trailer carries a tiltable platform having a rotatable plate on which the tank rests. The frame also carries a vertically movable apparatus for supporting either compaction rollers insertable into the tank top for compressing fodder as it is conveyed into the tank, or an elevator mechanism for lifting the tank away from its bottom cover to expose compacted fodder for removal. The tank is rotated during loading/compaction and removal. Compression of the fodder greatly increases the amount of fodder storable in each tank. After filling the platform is tilted, the tank is removed and can be rolled to a storage location with its axis horizontal.
Abstract:
The invention relates to a container (10) produced from a spiral-shaped, bent sheet strip (20), wherein the sheet strip (20) has a first edge section (22) extending in a spiral shape, which is bent, forming a bending edge (24) extending in a spiral shape, toward the inside or the outside of the container (10), and wherein the sheet strip (20) has a second edge section (32) which is opposite the first edge section (22) in relation to the longitudinal direction of the sheet strip (20) and likewise extends in a spiral shape, characterized in that the second edge section (32) of the sheet strip (20) overlaps a third section (28) of the sheet strip (20), which is opposite the first edge section (22) in relation to the bending edge (24) and is adjacent to the bending edge (24), in that the second edge section (32) and the third section (28) of the sheet strip (20) are welded to each other in the region of the overlap (30), and in that the welding seam (40) extends at least partially into the region between the second edge section (32) and the third section (28) of the sheet strip (20).
Abstract:
The invention relates to container produced from a single-layered, helically bent sheet-metal trip (20), wherein a first, helically running peripheral portion (22) of the sheet-metal strip (20) is bent out in the direction of the outside of the container (10) to form a helically running bent out edge (24), characterized in that the second, helically running peripheral portion (26) of the sheet-metal strip (20) overlaps a third portion (28) of the sheet-metal strip (20) on the inside of the container (10), said third portion being adjacent to the bent-out edge (24) and extending in the direction of the second peripheral portion (26) front the bent out edge (24), and in that the second peripheral portion (26) is connected in a fluid-tight manner to the third portion (28) of the sheet-metal strip (20) on the inside of the container (10).
Abstract:
A suspension cable is encased in a metal pipe formed from a metal strip wound in a series of adjacent helical windings on the cable. The longitudinal edges of adjacent windings are connected by a continuous tight fold.
Abstract:
A cable for structures, especially suspension bridges, has a plurality of bundled tension elements spacedly surrounded by a tubular sheath, the space between tension elements and sheath being filled with a material, preferably injected mortar. To reduce the cost of producing, transporting and assembling such a cable, the tubular sheath is formed at the worksite from at least one sheet-steel strip in a shaping and seaming station and progressed along already tensioned tension elements, then sealed against anchorings for the cable, and filled with the mortar under pressure.
Abstract:
One sheet section edge is bent to form two edge portions making a U shape with the sheet. The second sheet section has the adjacent edge bent to form two portions which lie adjacent the two edge portions of the first sheet section, a third portion formed by a 180.degree. bend and an additional bend to engage the inside of the U.
Abstract:
Apparatus for forming pipe from an elongated metal strip including a supply reel for the strip, an elongated tubular carrier, an axle at one end of the carrier for supporting the supply reel and edge-forming means for bending the edges of the strip to join them in a helical fashion to form the pipe wall. In one embodiment, the supply reel is supported at one end of the carrier and the strip is guided through the carrier and out through an opening near the other end. The carrier is supported for horizontal rotation. Near the opening there are guide rolls arranged in a helical path so that the strip emerges through the carrier, goes through the guide rolls, and then goes through the edge-forming devices including profiling and rabbeting rolls, also helically arranged. A motor is mounted at that end of the carrier and a chain drive from the motor drives the profiling and rabbeting rolls. In another embodiment, the supply reel and the guide rolls and profiling means are all at the same end of the carrier, the supply roll being supported within a frame and the guide and profiling rolls being supported on that same frame. The entire apparatus can be mounted on a carriage for longitudinal motion to advance as the pipe is produced. Alternatively, the forming apparatus can sit still while the pipe being produced is continuously withdrawn from the forming area.
