Abstract: Producing multilayer sheet metal strip stacks comprises feeding a metallic strip material having an upper side and a lower side by a feeding arrangement, longitudinally dividing of the fed strip material in a longitudinal direction of the strip material into a plurality of sheet metal strips in a continuous process by a strip dividing arrangement, and continuously superimposing of at least some of the sheet metal strips to form a sheet metal strip pack by a guiding arrangement.

Abstract: A process for producing plate springs or undulating springs wherein surface regions which are subjected to tensile stresses when the spring is under load are provided with an internal compressive stress in the boundary layer, wherein said surface regions are rollingly compressed by a ball or roller or subjected to tensile stress and compressed by shot peening.

Abstract: The invention relates to a head rest carrying element which is produced out of a tubular member and which, can be connected to a seat at one end, and which carries a head rest at its second end. The tubular member is produced by being formed out of a flexibly rolled strip material with a variable wall thickness. Furthermore, the invention relates to a process of producing such a head rest carrying element.

Abstract: The invention describes a device for the assembly and disassembly of a fastening device, more preferably of a rail fastening device on a support body, wherein the device is designed as screw adapter and the screw adapter is to be placed on the rail fastening device. The invention is based on developing a device for the assembly and disassembly of a rail fastening device which sits on the fastening device with an accurate fit and largely guarantees automated screwing in and screwing out of the fastening device in existing engagement stages. According to the invention this is achieved in that the screw adapter comprising an engagement pin at its stem, in the contact surface of its main body possesses a centrally arranged recess to accommodate the head of a fastening element, wherein the main body on both sides next to this recess comprises two mounting pockets designed trough-shaped as well as a stop.

Abstract: The invention relates to fixing means for fixing railway lines to sleepers or stretches of track, comprising an elastic rail clip (51) and a clip anchor element (31). According to the invention, the elastic rail clip (51) has retaining elements that can be inserted into the clip anchor element (31) and guided into the latter by being rotated about a rotational axis (D) and at least one pressure bow (52), which can be brought into pre-tensioned contact with the foot (24) of a railway line (21), when the elastic rail clip is rotated (51) about the rotational axis (D) in relation to the clip anchor element (31). The elastic rail clip (51) has essentially annular clip bows (55, 56) that act as the retaining elements and the clip anchor element (31) has guide elements (34) that are concentric with the rotational axis (D).

Abstract: An axially acting undulating washer or wave-shaped spring consisting of a closed annular member which comprises a central X-axis and which is periodically wave-shaped across the circumference, wherein a wave line extends so as to monotonically rise or fall between a plurality of identical minima and identical maxima and wherein in the minima and maximum of the wave line there are formed contact points of the annular member relative to axis-normal contact faces, wherein, starting from each minimum and maximum, the annular member, on both sides, i.e. in each circumferential direction, comprises at least two wave line portions which directly adjoin one another and which, with an increasing axial load, are individually flattened and made to contact and contact faces one after the other.

Abstract: Axial corrugated spring comprising an annular spring band 11 which describes a corrugation line oscillating about a radial reference plane around the circumference, wherein the corrugation line has maxima 12, 13, 17 of different height and minima 14, 15, 16 of different height.
