Definitions

  • the present invention relates to a sealing tape for sealing joints.
  • sealing tapes are commonly used for sealing joints, for example, between a frame profile of a window or a door and a building wall to seal the joints against draft and driving rain. Additionally provided films on a side surface of the sealing tape also increase the vapor impermeability of the same, see, for example EP 0 072 955 A1 or EP 1 936 246 A1 , However, films which are attached to the outside of the sealing tape, have the disadvantage that they can be damaged during transport or installation of the sealing tape.
  • a sealing strip roll which has at least one barrier layer extending in the radial direction, which is arranged between two layers of the foam and thus in the interior of the sealing strip roll.
  • the barrier layer consists of adhesive or of a lamination material.
  • large-area barrier layers are formed on plates of an open-pore foam material by lamination or gluing. Multiple layers of foam boards and barrier layers form laminate blocks. These laminate blocks are separated into sheets orthogonal to the large-area barrier layers.
  • the panels are then wound into wide rollers such that the barrier layers and the foam material are lined up on the circumference of the rollers in the axial direction. Such a wide roll is then separated between the individual barrier layers into slices to form several sealing tape rolls. This method requires many complex steps and the length of the sealing strips produced is limited by the size limitation of automatically machinable laminate blocks.
  • a foam sealing tape which comprises a barrier layer in the interior of the sealing strip, which changes the vapor diffusion permeability in the effective direction of the sealing tape.
  • the barrier layer material is inserted in a V-shape in the foam strip of the sealing tape.
  • the barrier layer may be double-layered in a similar manner. A connection of Foam strips on both sides of the barrier layer usually takes place via an adhesive layer on the top or bottom side of the sealing strip.
  • the present invention has for its object to provide a sealing tape with an inner film strip that is easy and reliable to produce with reduced energy requirements and its expansion after compression takes place without any restrictions.
  • the sealing strip according to the invention for sealing a joint has two longitudinal side flanks, wherein a direction transverse to the side flanks defines a functional direction of the sealing strip.
  • the sealing strip has at least a first foam strip and a second foam strip made of a soft foam which can be reset after compression, which are not formed integrally with each other and are arranged next to one another in the functional direction, each foam strip having an upper side, a lower side and an inner side edge facing the other foam strip ,
