Embodiments of the disclosure relate to a transfer pressing apparatus and method for forming car body parts, and more specifically, to a transfer pressing apparatus and method capable of automatically producing car body parts using rolled coils.

The invention relates to a method for preventing shape changes in metal coils, in particular for preventing a collapsing of newly wound hot coils. In the method, a metal coil, in particular a newly wound hot coil, is rotated about its longitudinal axis intermittently in a first rotational direction and then rotated back in a second opposing rotational direction, or further rotated in the first rotational direction.

A wire guide includes a solid core mandrel that is initially received in a flat wire coil that has a rest inner diameter that is greater than a uniform diameter of the solid core mandrel. The flat wire of the flat wire coil is in tension between a proximal location and a distal location so that the flat wire coil has a reduced inner diameter that is smaller than its rest inner diameter. The tension in the flat wire is introduced by torquing the mandrel relative to the flat wire coil as part of attaching the coil to the mandrel.

A rewind system includes a conveyor assembly and a rewind apparatus. The conveyor assembly is configured to convey strips along a plurality of paths each configured to convey at least one strip. The rewind apparatus includes a drum and a plurality of shafts. The strip on each path is rewound around one of the shafts. Two adjacent shafts do not take up strips simultaneously. The drum is configured to rotate around an axis of the drum. The drum is configured to switch each of the strips on different paths from one shaft onto another shaft after the drum rotates by a predetermined angle.

A pipe coil lifting device includes a superstructure with a central longitudinal member and at least two supports attached to opposite sides of the central longitudinal member, with two channels at the outside long-edges of the superstructure attached to the supports, with a convex upper surface attached to the supports of the superstructure.

A reversing reel includes a rotor, on which a reel mandrel with a rotary drive for winding strip into a coil is eccentrically arranged. A driven mandrel support device includes a mandrel support that has a bearing head for supporting a free end of the reel mandrel. The bearing head is movable with the reel mandrel when the reel mandrel is transferred from an initial-winding position into a final-winding position. The mandrel support is a first piston-cylinder arrangement, and the mandrel support is supported in a pivotable manner via a mandrel-support bearing on a slide that is movable tangentially to a circular path of the reel mandrel. The inclination of the mandrel support and the position of the bearing head are adjustable such that the mandrel support is oriented in accordance with a resultant force from the weight force of the coil and the tensile force on the strip.

A transport device (2, 50, 56, 88) for transporting a coil (4), comprising a coil transport cart (6) having a chassis (8) and having a coil support (10), which is height-adjustable relative to the chassis (8). In order to enable secure transport of the coil (4), the transport device (2, 50, 56, 88) has a movable fastening device (12) having a clamping unit (22) for pressing the coil (4) to be transported against the coil support (10). The clamping unit (22) being height-adjustable relative to the coil support (10) and being able to be at least partly inserted into a coil eye (42) of the coil (4). The fastening device (12) being fastened to the coil support (10) or to the chassis (8) of the coil transport cart (6). The coil support (10) having a cut-out (40), into which the clamping unit (22) can be at least partly lowered. Further disclosed is a use of such a transport device (2, 50, 56, 88), to a coil-processing system (70, 118) having such a transport device (2, 50, 56, 88), and to a method for transporting a coil (4).
