  • Patent number: 7392683
    Abstract: The invention relates to a method for the production of a rolled edge from an edge section (11) of a tube, wherein a flanging die is driven onto the edge section and flanges it into a roll. According to the invention, an initial area (14) of the edge section (11) is previously rolled in a positive fit manner by means of a forcibly controlled tool (30). This prevents buckling of the initial area (14), which has a controlled geometry as a result of rolling. The novel method is preferably used in the production of valve seats in so-called aerosol domes (10) for spray cans.

  • Patent number: 7019251
    Abstract: The invention relates to a method for producing lamella packets (e.g. 70) such as those used for adjustable steering columns in automobiles. According to the invention, at least one of the lamellae (e.g. 71) is provided with a collar (71.1) and is joined to another lamella (e.g. 72) so that the collar (71.1) of the first lamella (71) is supported against the other lamella (72) whereby defining the width (B) of a space between the lamellae (71, 72). Both lamellae (71, 72) are welded at at least one location of the collar (71.1). The welding is preferably carried out by resistance welding. In order to obtain defined ratios, the edge of the lamella collar (71.1) is preferably provided with projecting points (Z). The method is, among other things, advantageous in that the same material quality can be used for all lamellae (1–74).

  • Patent number: 6505856
    Abstract: A steering device for motor vehicles has a steering shaft that is guided by a guide box (3) which is connected to a retaining console and, for example, clamped. The console has at least one sliding surface (8) along the axis of the shaft (1) which allows for a displacement path (20) with respect to the chassis (18) in case of a collision. A clamp (17) is provided for axial retention of the console (6) in an initial position of the displacement path (20). In this way at least one part of the clamped surface is slanted in relation to the vertical clamping device so that the clamping surfaces can move away from each other when the steering shaft is displaced and clamping is reduced.

  • Patent number: 5178195
    Abstract: An apparatus for connecting at least two rods by a wire clamp comprises, mounted on one housing portion, a movable handle portion for the advance of said wire clamp, and closing jaws which are adapted to bring the locking portions of the wire clamp into engagement beneath the rods to be connected, and in the other housing portion, a binding hook fitted on a knurled rod, in order to twist the closed loop of the wire clamp which is situated above the rods to be connected. A sliding plate, which is connected to the handle, comprises a mechanism directed to actuating a bending pin on one of the closing jaws, in order to provide for positive interlocking of the wire clamp, and a mechanism for controlling and achieving safe individualization and advance of the wire clamps. Such an apparatus is adapted for reliable, swift and relatively comfortable operation even when exposed to the rough handling on a construction site.

  • Patent number: 5097567
    Abstract: In a method for connecting at least two rods, wherein a binding apparatus, which is provided with a rotatable hook member, seizes a wire loop, which extends around the rods, and twists the loop during a pulling movement. The wire clamp or clip which has leg portion ends provided with locking means is brought around the rods to be connected in such a manner that, when viewed from the hook member the locking means are brought into engagement with each other behind the rods, and the closed wire clamp in front of the rods is seized by the hook member of the binding apparatus and twisted.The device is required for this purpose includes a binding apparatus which has a slide member connected to a displaceable gripping member for the forward advancement of the wire clamp and closing jaws which are adapted to bring the locking members on the wire clamp into engagement behind the rods to be connected.

  • Patent number: 5054614
    Abstract: A twistable wire clamp for connecting objects has a V-shaped configuration, the lower portion of each of its two shanks forming an oblong loop having locking means consisting of the closed end of the narrower loop, on one hand, and of a locking member projecting towards the inside of the wider loop and extending in the same plane as the loop, on the other hand. On each side of the transitional portion between said two shanks, said clamp is provided with a respective shoulder. Said clamp is placed, by means of an apparatus, around the objects to be connected or the opening to be closed, after which said locking means are brought into engagement with one another by said apparatus, and said wire clamp is seized in the area of said transitional portion and twisted by a binding hook of the apparatus. Said loops are convex with respect to their plane, and said closed end portion has a thinning and is bent over towards said other loop.
