Definitions

  • the invention relates to a method for producing an insulating element which has at least one insulating layer provided with an adhesive layer, the adhesive layer being covered with a removable protective element layer.
  • the present invention further relates to an insulating element produced by this method.
  • noise insulation elements are used which are provided with an adhesive layer for attachment to the vehicle.
  • the adhesive layer is provided with a removable protective element, which can be, for example, a protective paper or a protective film.
  • a removable protective element which can be, for example, a protective paper or a protective film.
  • the invention has for its object to propose an insulating element and a method for its production, in which the removal of the protective element is facilitated.
  • raw material consisting of at least one insulating layer, at least one adhesive layer and a protective element layer applied thereon, is provided such that the protective element layer is partially removed by folding away from the insulating layer and the adhesive layer, so that the desired shape of the insulating element is cut, the folded protective element layer is only partially grasped and a folded pull tab is formed is, and that the folded trigger tab is returned to the cut insulating member.
  • the pull tab formed by the method according to the invention makes it easier to pull off the protective element, since the pull tab projects beyond the outer contour of the insulating element.
  • the pull tab provides a sufficiently large grip area for pulling off the protective element.
  • the protective element layer is advantageously raised or folded over in regions. This ensures that when punching or cutting the insulating element, the area of the protective element layer forming the pull tab is not detected.
  • the cutting edge of the insulating element is arranged at a short distance from a buckling edge of the protective element layer.
  • the insulating element is advantageously a sheet metal or a foil for noise insulation. Such insulating elements are used in particular in the automotive sector.
  • Fig. 1 shows a plan view of an insulating element 10, which is used for noise insulation in motor vehicles.
  • the insulating element 10 has an outer contour 11 which is adapted to the particular application. Furthermore, a cutout 14 is provided on the insulating element 10.
  • the insulating element 10 consists of an insulating layer 15, for example a metal sheet or a film for noise insulation.
  • the top of the insulating layer 15 is provided with an adhesive layer 16.
  • a removable protective element layer 12 is applied thereon.
  • the removable protective element 12 is still applied to the adhesive layer 16.
  • it is provided with a pull tab 13.
  • the pull tab 13 provides a sufficiently large grip area so that the protective element 12 can be removed from the adhesive layer 16 in a simple manner.
  • a raw material is initially provided, the basic structure of which can be seen in FIG. 2.
  • the raw material has an insulating element layer 15, to which an adhesive layer 16 is applied.
  • the adhesive layer 16 is provided with a removable protective element layer 12.
  • the protective element layer 12 is removed in some areas from the insulating layer 15 or the adhesive layer 16. 3, this can be done by raising the protective element layer 12 in some areas. The protective element layer is thus approximately in regions vertically upwards. In this way, a crease edge 17 is formed. The adhesive layer 16 is released in the folded-down area of the protective element layer 12.
  • the protective element layer 12 can also be completely folded over so that it rests on the top of the areas of the protective element layer 12 that have not been removed. In this case too, there is a kink edge 17 of the protective element layer 12.
  • the cutting tool is guided so that the folded protective element layer 12 is only partially covered.
  • the cutting tool is aligned obliquely to the crease edge 17 in the region of the pull-off tab 13 to be formed, so that the folded protective element layer is only partially detected.
  • a cutting edge 19 is provided, which is arranged at a short distance from the bent edge 17 of the pull tab 13. In practice, the dimensional accuracy of the cutting tools is so precise that this can be done easily.
  • the pull tab 13 is transferred from the folded position to the position shown in FIG. 1.
  • the pull tab 13 protrudes laterally over the cutting edge 19, so that a sufficiently large gripping surface is provided for pulling off the protective element 12.
