Abstract: A coiling device that includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip, and a coiling swing arm (4) having front and a rear pressure rollers (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) guides the metal strip (2). A flap drive (10) positions the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4).

Abstract: 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.

Abstract: Device for winding a material web, particularly a metal strip, wherein a coil (1) is supported during the winding process by at least two support rollers (2, 3), wherein the support rollers (2, 3) can be jointly pivoted about a pivot axis (18) between a first, substantially horizontal, position and a second position, which is inclined relative to the horizontal position, by means of a pivoting device (11).

Abstract: A device (1) and a method for holding together and transporting a metal band rolled into a coil (3) after the band is rolled in a coiling station (5). The device (1) includes a removal trolley (20) for receiving the coil (3) in the coiling station (5) and for transporting the coil (3) from the coiling station (5). A coil safety device places a securing sling (40) around the coil (3) fixed on at least part of the circumference, such that the coil (3) is held together by the securing sling (40) and is pressed onto the removal trolley (20).

Abstract: A transporting system for transporting metal coils, for example hot coils, may include a multi-track rail system; a number of driverless transporting carriages, which can be moved on the rail system by means of a drive device and are equipped with an on-board communication device; a locating device, with which up-to-the-moment locational information can be determined for each transporting carriage located on the rail system; and a central control device, to which the locational information of each transporting carriage can be fed, wherein a communication link, which at least in certain sections is formed without any lines, can be established between the control device and the communication device.

Abstract: A plurality of chips disposed in a wafer on a passivated main side, having at least one chip contact surface, is provided with an insulation layer. The insulation layer has openings in the area of the at least one chip contact surface of each chip. The chip contact surfaces of each chip are provided with a chip contact surface metallization of a prescribed thickness, and the chips disposed in the water are separated therefrom.

Abstract: A device for forming stacks of sheet products, in particular of paper products, may include the paper products being supplied in an input stream by a feed conveyor to a transfer section. The device may also include at least two set-down tables each including a set-down surface for receiving stacks of the supplied paper products. The set-down tables may move along a circuit-like table-circulating path and may be flexible at least in some segments to conform to shapes of curvatures located in at least some parts and subregions of the table-circulating path. As a result, it is possible for the set-down tables to be guided into the curvatures with a leading front side edge of each of the set-down tables being a leading edge in a circulating direction of the set-down tables. The stacks of stacked paper products may then be transported away from a delivery section by a removal conveyor.

Abstract: A first conveying device has first bearing elements which are arranged parallel to one another and define a planar first bearing surface. The first bearing elements are driven such that they can be displaced in a first conveying direction. A second conveying means has second bearing elements which run parallel to one another and to the first bearing elements and define a second planar bearing surface. The second bearing elements are designed as conveying elements which are driven in a second conveying direction, which runs at right angles to the first conveying direction. The second bearing elements can be displaced, by means of a lifting drive, in a lifting direction, which runs at right angles to the two bearing surfaces. The first and second bearing elements are spaced apart from one another and arranged such that, upon displacement of the second bearing elements, the latter can be pushed through the interspaces between the first bearing elements.

Abstract: A process for purifying organically polluted salts comprising forming a melt of said salts at a temperature of from about 600.degree.to 1000.degree. C., and contacting salt melt with an oxygen-containing gas. Acidic or basic fluxes may be present. The heat to maintain the mass molten may be supplied by electrodes which dip into the melt and which may be hollow so oxygen can be introduced therethrough. A suitable apparatus is also described.
