Definitions

  • the invention relates to a special mesh, consisting of a conventional wire mesh with subsequently contacted ends of each individual spring.
  • the individual springs are stripped at both ends. After or during the rotation with the next spring, electrically conductive connections are made. Then the stripped points are again covered with insulating material.
  • Mesh wire mesh produced in this way can also be used in a variety of other ways (for example in a wall as a breakthrough detector or for monitoring skylights).
  • the metal core of the wire would have to have an appropriate shape in order to further ensure a round wire to the outside.
