  • Publication number: 20090070983
    Abstract: The present invention discloses a self-piercing element, that can be fastened to a structural component by means of piercing and beading. Additionally, the present invention discloses an apparatus for seating the self-piercing element and a corresponding method. The self-piercing element comprises a functional head, a seat geometry and a cutting geometry, while the cutting geometry has a radially outwards arranged, centering exterior bevel, a radially inward arranged interior bevel and a cutting edge arranged in between.

  • Patent number: 6682781
    Abstract: A wetting device for the mat (10) of a carrier material comprises a grasping frame which is constituted by side ledges (101, 102, 104), whereby the mat to be coated (10) can be fixed by clamps (105) to the side ledges. At least one of the side ledges of the frame is configured flexible (bendable), since it preferably comprises several segments (101, 102) which are hinged together. Thus, the clamped mat (10) can be brought into a cylindrical configuration in which it can be coated by a spray device which is introduced into the inner space of the cylinder. Due to the subsequent bending of the flexible side ledge in the opposite direction, the mat (10) can be brought into a second cylindrical configuration for which its other upper surface constitutes the inner side of the cylinder and is thus available for being coated by the spray device. During the spraying operation, the cylinder axis is preferably orientated vertically in order to avoid non-homogeneities of the coating because of the gravitation.
