  • Patent number: 5318282
    Abstract: In a vibration damper, a load-attachment unit carried by a spring member has an axially supported fixing screw with a threaded section pointing upwards, the head of the fixing screw being accessible by way of openings in a fastening part supporting the fixing screw, the spring member and a base plate from the underside of the vibration damper, so that the vibration damper may be located on those machine parts in which there is no possibility of access to the support point from above.

  • Patent number: 5289853
    Abstract: For producing an all-metal spring cushion, a knitted piece knitted from spring wire is wound in a winding sleeve (14). In the winding sleeve (14), the end of the knitted piece is fixed to the knitted roll (76) by micro-welding. In a pressing station (22), the winding sleeve (14) is flush and aligned in front of a pressing sleeve (148) of the same inner diameter. The knitted roll is pushed into the pressing sleeve (148) by a press die (162) and compressed therein to form a spring cushion. Then, the spring cushion is ejected from the pressing sleeve.
