Definitions

  • the invention relates to a covering material with a flat plastic body, which has high extensibility in every surface direction, and one stretchable metal insert and a process for its production.
  • Flat covering materials for example as sheets or sheets on the Are available on the market as constructive building materials, such as Sealing materials used on roof element transitions. Furthermore, they will often used as a touch-up material, for example on waterproof items Flaws in the roof area.
  • Covering materials In order to be able to adapt well to underlying components, such should Covering materials must be easily stretchable and plastically deformable. Known covering materials use to provide an elasticity and plastic deformability To achieve a certain stability, metal inserts that are in the plastic flat body are involved.
  • DE 22 25 358 C2 discloses a prefabricated arched or web-shaped sealing material known from a bitumen / rubber mass. It is suggested, Metal as a foil or stretched or perforated metal layer in the sealing material bring in.
  • DE 33 10 989 A1 discloses a plate-shaped seal made of a permanent deformable material that is a metallic wire insert in the form of a wire mesh having.
  • DE 36 42 063 A1 describes a plastically deformable covering material known that an expanded metal grid as a stretchable reinforcing element has that is extensible in one direction, but in the perpendicular to it Direction has only a little stretch.
  • the two above-mentioned writings each reveal lattice or braid structures, in which the extensibility of the deformability of the metal grid structures comes from.
  • the two above-mentioned writings each reveal lattice or braid structures, in which the extensibility of the deformability of the metal grid structures comes from.
  • this can stretch it that a tensile force is applied at an oblique angle to the mesh lines and this will deform into diamond-shaped meshes.

This has the particular disadvantage that when Applying a tensile force that acts exactly in the direction of the web or wire, one Elasticity of the cover material is no longer given, because of such Traction would not change the shape of the mesh. If forcibly one Elongation in the direction of the individual grid or braid wires or should be brought about, they would tear and the covering material make it unstable.
  • a covering material with a flat plastic body is provided with a metal insert that Has wires which, substantially in the plane of the surface, in the direction of their Longitudinal extension are gathered.
  • the gathering of the wires can be carried out so that they have an undulating, have a meandering or zigzag shape.
  • the advantage of the present invention resides mainly in the fact that from metal inserts with straight wires or webs to shirred Wires is transferred, which also in the direction of their longitudinal extension can be stretched due to their gathering.
  • the resistance to longitudinal expansion, of metal inserts with straight webs or Wires shows no longer occurs with gathered wires.
  • Metal insert is pulled in the direction of the longitudinal extension of the wires, the individual wires will already be extended by the fact that the gathering "pulled apart". When pulling apart, depending on the type of Gathering, for example just a slightly straighter wavy line a somewhat straighter zigzag course or a somewhat expanded meandering Line. The traction no longer acts on you, as in the prior art already stretched body, causing tearing of the wires due to elongation no longer have to be feared.

  • the metal insert is made of at least one wire runs in the surface of the plastic body so that none Crossing points arise between wire sections, which are in particular area-like, is designed essentially meandering. So here is the wire itself gathered and becomes a flat surface before being inserted into the plastic body Form laid that a wire sheet is created from a single wire.
  • Such an embodiment of the metal insert has in particular the manufacturing advantages, since no braiding processes have to be carried out; the Two-dimensional wire structures can only be produced by bending.
