Definitions

  • the present invention relates to a method for producing a sealing tape and to a sealing tape.
  • a variety of sealing strips for a wide variety of applications are known.
  • sealing tapes are known which have a coating on a foam carrier, which should reduce, for example, the vapor diffusion.
  • Various approaches for the production of such sealing tapes are known from the prior art. For example, it is known that a foam carrier is cut open and a foil is introduced into a cutting region.
  • the present invention is therefore an object of the invention to provide a method which allows a simpler way to produce such sealing tapes. This object is achieved by the subject of the independent claim. Furthermore, the present invention has for its object to provide a sealing tape available, which on the one hand allows a simple arrangement on a component or a wall and on the other hand causes a satisfactory sealing effect.
  • a foam carrier is first provided and transported at least temporarily in a predetermined transport direction.
  • a coating is applied to a first surface of the foam carrier.
  • the foam carrier is cut into at least two and preferably a plurality of strips. Furthermore, a self-adhesive is applied to a further surface of the individual strips.
  • each of the cut strips has a coating on one surface and a self-adhesive on another surface.
  • these two surfaces are perpendicular to each other.
  • these strips each have a substantially rectangular cross-section.
  • At least one and preferably a plurality of the cut strips are rotated by a predetermined angle. It would be possible that only one of the cut strip is rotated, it could be more of the strips or all of the strips are rotated by a predetermined angle.
  • this rotation takes place with respect to a longitudinal direction of the individual strips and / or a direction which is parallel to the transport direction.
  • all strips are uniformly rotated and / or rotated in each case by the same angle.
  • the coating is attached or attached without gaps and / or continuously to the foam carrier.
  • the said cuts also extend in a transport direction of the foam carrier.
  • the foam carrier rests when introducing the cuts, for example, is on a shelf.
  • the foam carrier extends in the transport direction and in a direction perpendicular thereto width direction.
  • the foam carrier in the said width direction for example, extend by one meter.
  • the coating is a flexible coating.
  • This is advantageously a thin coating.
  • This particularly preferably has a thickness which is between 10 ⁇ m and 1 mm, preferably between 50 ⁇ m and 200 ⁇ m.
  • the coating is particularly preferably selected from a group of coatings which contain plastic materials.
  • a coating is first applied to the first surface of the foam carrier, then the cutting of the foam takes place and then the self-adhesive is applied.
  • the advantage of using an elastic and / or flexible film and / or lamination or coating lies in the fact that it is easier to apply longitudinal edges of this layer to joint flanks, the so-called flank closure.
  • the lamination or the coating should meet these requirements.
  • these coatings it would also be possible or additionally possible for these coatings to be UV-resistant, water-resistant, impact-proof, paintable and / or renderable.

  • adhesives or sealants could be used, which contain in particular, but not exclusively, silicones, PU, acrylates, hybrid sealants, PVAC and the like. Also, modifications of these substances could be used.
  • the coating is attached by means of a film and in particular a hotmelt film on the foam.
  • a film and in particular a hotmelt film on the foam It is possible, for example, that an impregnated foam web travels out of a dryer. From each supply roll, a hotmelt film and a coating or laminating film are then unrolled and deposited on the foam.
  • This package can then be run or transported through a laminating system with which by means of a predetermined temperature, for example a temperature which is between 80 and 200 °, preferably between 100 and 180 ° and particularly preferably between 120 and 160.
  • the hotmelt film between the foam and the laminating film or the coating melt and in this way the composite of the foam with the film is produced.
  • the foam sheet is not only coated on one side, but on both sides, and in particular on two mutually opposite sides. It is then conceivable that these top and bottom of the precursor of the foam sheet result in an inner and outer side of the final product sealing tape.
  • the advantage of such a two-sided lamination or application of a coating on both sides could be coatings with different properties, especially for the requirements of the orientations end product. Conceivable here would be, for example, a UV-stable coating and a vapor-open coating on an outside and on the other hand, a vapor-tight or vapor-damping and airtight coating on the inside.
  • the foam carrier is transported continuously.
  • a timed transport would also be conceivable.
