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.
  • the present invention has for its object to provide a sealing tape with an inner barrier layer, which has variable properties and can be produced with reduced energy requirements.
  • the sealing tape according to the invention for sealing a joint comprises two longitudinal side flanks, wherein a direction transverse to the side flanks defines a functional direction of the sealing tape.
  • the sealing strip has at least a first foam strip and a second foam strip made of a resilient foam which can be restored after compression, which are not formed integrally with one another and are arranged side by side in the functional direction, each foam strip having an upper side, a lower side and an inner side edge facing the other foam strip ,
  • the sealing tape also includes a barrier layer disposed between the first foam strip and the second foam strip such that it reduces vapor transmission permeability of the sealing tape in the operative direction, the barrier layer being adhesively bonded to both the first foam strip and the second foam strip, and wherein the barrier layer is at least partially formed from a first film strip. In a region between the first foam strip and the second foam strip and at least including the first film strip of the barrier layer at least one longitudinal pocket or at least one longitudinal cavity is formed, which is completely enclosed on at least four sides.
  • a sealing tape in which a barrier layer is arranged protected inside the sealing tape and in which the properties of the barrier layer can be made variable.
  • a desired additional material can be received in the pocket or the cavity in order to give the sealing tape special properties.
  • traps between the first film strip of the barrier layer and the first foam strip are only in an upper region of the first foam strip on top of the first foam strip and / or on the inner side edge of the first foam strip near the top of the first foam strip and in a lower region of the first Foam strip disposed on the underside of the first foam strip and / or on the inner side edge of the first foam strip near the bottom of the first foam strip, while in a middle region between the upper portion and the lower portion of the first foam strip, the first film strip of the barrier layer not with the first foam strip is arrested.
  • the sealing tape can be simple and are manufactured inexpensively, and the expansion of the sealing tape is not limited despite the presence of the barrier layer.
  • the detents between the first film strip and the first foam strip are located only on the inner side flank of the first foam strip near the top of the first foam strip and on the inner side flank of the first foam strip near the bottom of the first foam strip. In this way, in the production of the sealing tape already a short-term heating from above and from below enough to form the traps.
  • the longitudinal pocket is formed at the level of the central region of the first foam strip.
  • the pocket is enclosed by the first film strip and the first foam strip. In this way, the pocket is produced automatically in the production of sealing tape if the points of adhesion between the first film strip and the first foam strip are present only in the upper region and in the lower region of the first foam strip.
  • the first film strip may be fully adhered to the inner side edge of the second foam strip.
  • the first film strip may be adhered to the top and / or bottom of the second foam strip.
  • a particularly simple production of the sealing tape is obtained when the adhesion points between the first film strip and the second foam strip are arranged only on the inner side edge of the second foam strip near the top of the second foam strip and on the inner side edge of the second foam strip near the bottom of the second foam strip. In this way, the traps between the first film strip and the first foam strip and the traps between the first film strip and the second foam strip can be produced simultaneously in the same process step.
  • the first film strip may be fully adhered to the inner side edge of the second foam strip, and the detents between the film strip and the first foam strip are disposed on the top and bottom of the first foam strip.
  • the barrier layer of the sealing tape has, in addition to the first film strip, a second film strip which is adhesively bonded to the second foam strip.
  • the first film strip is adhesively bonded to the second film strip, and traps between the first film strip and the second film strip are disposed only in an area near the top of the first foam strip and in a region near the bottom of the first foam strip, while in an intermediate region between the traps of the first film strip and the second film strip are not arrested with each other.
  • the foam strips can already be equipped in an upstream production step with the first film strip and the second film strip, and the arrest of the two equipped foam strips takes place only by arresting the two film strips in a later process step.
  • the longitudinal pocket is formed in the intermediate region between the adhesion points and thus between the first film strip and the second film strip.
  • the barrier layer has a longitudinal tubular body formed at least in part from the first film strip, the tubular body forming the cavity in its interior and being adhered to both the first foam strip and the second foam strip.
  • the pocket or the cavity is enclosed by all six sides.
  • the barrier layer has a tear tab, which can be opened by pulling on the tear tab, the pocket or the cavity.
  • the contents of the pocket or the cavity can be selectively released or activated, for example, only after installation of the sealing tape.
  • two reactive materials can be selectively associated with each other, which were previously stored separately in different chambers of the cavity or the bag.
  • the adhesion points are formed as longitudinal adhesive lines. As a result, a continuous arrest of the two foam strips is guaranteed to each other, which can also be generated in a simple manner.
  • the pocket or cavity is filled with a filler material.
  • a particularly simple production of the sealing tape according to the invention is ensured if the traps are formed by melting and subsequent curing of a bonding material, in particular an adhesive.

  • the tear tab 146 preferably has a length that allows the tear tab 146 to project laterally beyond either the second foam strip 116 or the first foam strip 114 to allow the tear tab 146 to remain tangible to the user when installed.
  • the tear tab 146 may attach to any point on the tubular body 144. However, it is preferred if it attaches in an area near the top 118 of the first foam strip 114 and near the top 124 of the second foam strip 116, respectively.
  • the tear tab 146 can also be used in any other form of the sealing tape 2 according to the invention, in which there is a completely enclosed pocket 34 on at least four sides, preferably six sides, or a cavity 150 completely enclosed on at least four sides, preferably on six sides ,
  • a tear tab 146 a tear thread or other suitable tension element can also be used.
  • the filling of a pocket 134 may preferably take place during the manufacturing process of the sealing tape 2.
  • the filling could be done in a state in which the pocket 134 is still enclosed on only three sides, while it is still open on the fourth side. From this fourth open side, the additional material 140 could be inserted into the pocket 134, whereupon the pocket 134 on the fourth side, preferably by means of a trap 132, is closed.
  • the cavity 150 is preferably already filled and enclosed in an upstream process step.
  • the filled with the additional material 140 tubular body 144 is then inserted as a whole between the two foam strips 114, 116 and arrested at this.
  • a plurality of foam strips 114, 116 can also be arranged next to one another and connected in the manner according to the invention.
  • a barrier layer 30 should be arranged with at least one foil strip 130 between each two foam strips 114, 116.
  • sealing strips 2 of any shape can be produced, with foam strips 114, 116 and barrier layers 30 preferably alternating in the direction of operation F, and in each case preferably one foam strip 114, 116 being arranged on one edge of the sealing strip 2.
  • Fig. 17 shows an installation situation of an unwound from a sealing tape roll sealing tape 2 according to the invention
  • the installation situation should apply in principle to all embodiments of the sealing tape 2 of the invention.
  • the reference numeral 30 here generally for the barrier layer, which is provided with the pocket 134 or the cavity 150, representative of the specific embodiments, as they have been explained for example in the previous figures.
  • the sealing tape 2 is usually first unwind from the sealing tape roll and cut into strips of any length.
  • the length of the sealing strip strip is adapted to the outer contours of a sealed window frame or a door frame.
  • the sealing tape 2 is then preferably fixed to the window frame 112 or door frame by means of the adhesive layer 80 or by means of other adhesive layers, adhesive tapes or other suitable means.
  • the adhesive layer 80 When using a double-sided adhesive tape as the adhesive layer 80, therefore, only the release liner 81 must be removed before the sealing tape 2 can be attached directly to the window frame 112.
  • the sealing tape 2 between a window frame 112 and a masonry 110 is added to seal the intervening joint.
  • the barrier layer 30 is protectively received between the foam strips 114, 116, whereby damage during storage, transport and assembly of the sealing tape 2 are avoided.
  • the sealing tape 2 is to be installed so that at least a barrier layer 30 extends from the window frame 112 to the masonry 110 and thus substantially orthogonal to the functional direction F of the sealing tape 2.
  • the functional direction F extends parallel to the surfaces of the window frame 112 and the masonry 110 forming the joint to be sealed from a room outside (in FIG Fig. 17 left) to a room inside (in Fig. 17 right).
  • a film strip 130 may be used whose vapor diffusion tightness adapts variably to the ambient conditions.
  • the barrier layers 30 of a sealing tape 2 may also have different vapor diffusion impermeability.
