Abstract: A method of expanding an elongated and at least regionally planar metal element that has two respective marginal regions oppositely disposed and extending in a longitudinal direction and a central region arranged therebetween and including cuts, the marginal regions of the metal element are moved apart transversely to the longitudinal direction and in parallel with a planar extent of the metal element such that connection portions of the central region formed by the cuts and connecting the two respective marginal regions to one another are folded, the method includes displacing the two respective marginal regions with respect to one another transversely to the planar extent of the metal element to form a displaced state, and subsequently moving apart the two respective marginal regions in the displaced state.

Abstract: The invention relates to a profiled element with an elongated profiled body that consists of metal or plastic in particular. The profiled body comprises at least two separately designed longitudinal portions, each longitudinal portion comprising a meandering longitudinal edge and a rectilinear longitudinal edge that lies opposite the meandering longitudinal edge. The longitudinal portions are connected to each other by the rectilinear longitudinal edges. The invention further relates to such a profiled element in which the longitudinal portions can be designed separately or as a single piece, said profiled body having a substantially U- or V-shaped cross-section with two profiled limbs and a profiled connecting piece that connects the profiled limbs.

Abstract: A device and a method for widening elongated metal elements which move in the longitudinal direction and are planar at least in certain regions are described. The device comprises at least two clamping sections which are opposite one another and of which one is arranged and designed for clamping a first longitudinal side of the metal element in place and the other is arranged and designed for clamping a second longitudinal side of the metal element in place, said second longitudinal side being opposite the first longitudinal side of the metal element. The clamping sections are each provided on a support unit by means of which the clamping sections, during the forward movement of the metal element, are automatically moved apart essentially perpendicularly to the direction of movement of the metal element.

Abstract: The invention relates to a profiled element, in particular a profiled construction element, for example a profiled dry construction, façade, or plaster element, comprising an in particular metal elongated main body, in which at least one opening is formed. The opening has at least one edge formed transversely to the longitudinal extension of the main body, which edge is formed at least partially by a bent-over section of the main body. The bent-over section, together with an adjacent section of the main body, forms an at least double-layer area of the main body. In order to increase the stiffness of the profiled element transversely to the longitudinal extension thereof, the bent-over section is connected to the adjacent section within the at least double-layer area. The invention further relates to a method for producing such a profiled element.

Abstract: A profiled rail for supporting plate-shaped elements, particularly for inlay mounting of ceiling plates for louvered ceilings includes a base body, having a T-profile in select areas, a longitudinally extended web and a lower flange. The lower flange runs along a longitudinal edge of the web and comprises two lower flange sections each extending from the web essentially in opposite directions. The lower flange is formed by bending the web. The side of the lower flange, which is oriented away from the web, is provided with a facing board. A multitude of openings are provided in the web, whereby at least one of the lower flange sections is formed by material sections of the web that are folded out from the openings. The web is provided as a single layer essentially over its entire surface. A method for producing a profiled rail of this type is also provided.

Abstract: A friction lining for use in the clutch plate of a friction clutch or a multiple wrap brake band for use in an automatic transmission is obtained by adhesively securing one side of a friction generating second layer to one side of a metallic first layer. The necessary incisions in the form of cuts, slots or slits are made from the exposed side of the second layer in a direction toward the exposed side of the first layer by resorting to one or more high-energy streams, such as laser beams, electron beams or liquid jets. Each incision can be made in one or more stages by a single stream or by a series of successively applied streams.
