    Abstract: The apparatus comprises a first working unit for unwinding a coil of conductor and providing straightened conductor, and a second working unit comprising a bending device arranged to bend the straightened conductor leaving the first working unit and a rotary table on which the bent conductor leaving the bending device is laid, whereby a set of turns is formed to make the superconductive coil. The rotary table is rotatably mounted about a stationary vertical axis. The bending device is mounted so as to be translatable both in a longitudinal direction coinciding with the direction of a longitudinal axis of the straightened conductor that is fed by the first working unit to the bending device and in a transverse direction perpendicular to the longitudinal direction. The first working unit is mounted so as to be translatable, along with the bending device, in the transverse direction only.

The dimension of the coil is decreased in the widthwise direction by the nearly same dimension as that of the coil bulged in the widthwise direction when bending work is conducted in the absence of the preliminary forming work. This prevents the occurrence of bulging of the coil during bending work with an increase in lamination factor.

The mandrel (11) also comprises first arm elements (13) which define the cylindrical surface of the core that forms the coil (31), and second arm elements (14), opposite the flange (12), which define a second flank of the coil. The first and the second arm elements (13,14) are mobile between a first coil-forming position and a second coil-removal position.

  • Patent number: 7401485
    Abstract: Steel strip issues continuously from a downstream end of a rolling line and can be wound up there on a coiler. An inspection table downstream of the rolling line has a surface aligned with the downstream end and the strip emerging therefrom. The coiler is below a plane of the table surface. During normal rolling the strip is deflected downward to the coiler and reeled up. For inspection of the strip, the strip is cut transversely to produce a new leading end and is fed starting at this end toward the table without substantial deflection. Then the strip is cut again upstream of the new leading end to form a strip sample separate from the strip emerging from the rolling line, which sample is fed to the table and arrested and inspected while strip emerging from the line is deflected back down to the coiler to continue coiling it up.

  • Patent number: 7398666
    Abstract: The invention relates to a method of rolling a strip-shaped in-process stock, in particular a metal strip, with which, a metal strip (3) is unwound from a coil (2, 7) held on an unwinding reel (1, 6), is fed into a reversing rolling mill (8), is rolled, and is wound-up onto a winding-up reel (9) to form a coil (10), wherein the metal strip (3) is reversibly conveyed from the unwinding reel (1, 6) to the winding-up reel (9) until a set thickness is reached and, with each passing of the reversing rolling mill (8), is subjected to a reduction of thickness, and wherein an end of the metal strip (3) of a first coil is welded to a beginning of the metal strip (3) of the second coil, and the metal strip (3) of the first coil is temporarily stored in a strip store during a welding process, and finally, the in-process stock consisting of two lengths is reversibly rolled to a final dimension, and an additional length is welded to the end of the in-process stock before the last pass.

  • Patent number: 7392682
    Abstract: A method for coiling thin metal strip, especially hot-rolled or cold-rolled thin steel strip, on a coiler mandrel which is adjusted in diameter. At the beginning, the inner windings of the coil are coiled on the adjusted coiler mandrel diameter and, after the final winding of the coil, the coiler mandrel is pulled out or the coil is taken off. At least the first inner winding is joined over a large area with the second inner winding by introducing adhesives, fillers, pieces of metal, bonding agents, or the like into an angular space between the inner windings.

  • Patent number: 7293446
    Abstract: The invention relates to a coil box, which is mounted between a roughing rolling train and a finishing rolling train, for metal pre-strips, in particular steel strips, which are hot wound to form coils and are protected against further cooling in the vicinity of a winding and/or unwinding station (6) by means of heat-shield devices (7) on the front faces (5a; 5b) of the coils. The aim of the invention is to universally configure said coil box. To achieve this, the heat-shield devices (7) are configured from lateral walls (8; 8b) that can be pivoted to rest against the front faces (5a; 5b) of the coils and a pair of opposing heat-shield devices (7) can be aligned in parallel to different coil widths (5c).

  • Patent number: 7290421
    Abstract: A tube is bent having a curved portion with a variable radius extending between first and second ends. The curved portion includes a circular arc portion with a constant radius and a clothoid transition portion with a variable radius. The circular arc portion extends from the first end toward a point of integration. At the point of integration, the circular arc portion merges with the transition portion. The transition portion extends from the point of integration to the second end. As the transition portion extends from the point of integration, its radius of curvature increases over its arc length, thereby, improving the quality of the bent tube by gradually bending the tube over a longer distance, thereby reducing local stresses on the bent portion of the tube.

  • Patent number: 7251976
    Abstract: A tube bending apparatus adapted for the noncircular bending of a tube includes a modified bend die, a modified wiper die, a translatable and pivotable element and an actuator. The bend die presents a noncircular bending profile having a linearly or nonlinearly increasing radius of curvature. The wiper die is configured to accommodate the maximum radius presented by the profile, and the element and actuator present an inclined rack and pinion configuration. The bend die presents an involute of a circle having a radius equal to the product of the radius of the pinion and the sine of the angle of inclination, so that the bend die engages the tube at a fixed point in space during bending.

  • Patent number: 7181946
    Abstract: The aim of the invention is to configure a device for winding and unwinding partly rolled products, in a way that ensures the smallest possible accumulation of scrap. To achieve this, a roller (20, 20?, 20?) whose position is controlled and which runs on the periphery of the coil is used during the transfer of the coils from the winding station to the unwinding station. The vertical adjustment of said roller ensures that the coil is completely unwound, even with a diminishing coil diameter.

    Abstract: The invention relates to a plurality of methods and devices which are used to wind a thin metal strip (1), especially a hot rolled or cold rolled thin steel strip, onto a winding mandrel (3a), the diameter thereof being adjusted. To begin with, the coil en inner windings (12,18) are wound onto the adjusted diameter of the winding mandrel, and after the coil (11) has been wound, the winding mandrel (3a) is removed or the coil (11) taken off. According to a first method, in order to prevent individual windings (12,18) from detaching themselves in the eye of the coil (15) due to stiffening of windings, at least one profiled rise or profiled cavity is pressed into one inner winding or a plurality of adjacent inner windings (12,18) on the circumference during rotation of the coil.
