Definitions

  • the present invention relates to a sealing tape, in particular for sealing joints.
  • Sealing tapes or sealing tapes are known from the prior art, which have a self-adhesive layer and a plastic tape serving as a support and in which an adhesive layer is covered by means of a removable cover film, also referred to as a liner, prior to using the tape. It is also known that these cover sheets are slit in the longitudinal direction to facilitate the bonding of the sealing strip.
  • Such sealing tapes are used for example for closing, sealing and bonding joints in house construction, but in particular also for bonding joints in corners and edges. These may be, for example, window joints.
  • the present invention is generally based on the object of providing a sealing tape, in particular for sealing joints, which is easier to handle than sealing tapes of the prior art. This object is achieved by the subjects of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.
  • a sealing strip according to the invention extends in a predetermined longitudinal direction and in a transverse or width direction perpendicular thereto. Furthermore, the sealing tape has a base support which extends in the longitudinal direction and at least partially in the width direction, wherein the sealing tape has at least two longitudinally extending strips, each having a first surface and a second surface which is opposite to this first surface , and these first surfaces are arranged on the same side of the sealing strip. Furthermore, at least the first surface of the first strip differs from the first surface of the second strip in terms of their adhesive properties. In addition, at least one surface of the second strip has an adhesive element.
  • first surfaces and also the second surfaces
  • these first surfaces need not necessarily be formed on the base support itself, but may also be laterally offset from this. (This may apply in particular to the second strip),
  • the specification of the being arranged on the same side is to be understood only in a geometrical sense or with regard to the two opposite surfaces or sides of the sealing strip.
  • a sealing tape which at least in the width direction or perpendicular to the longitudinal direction.
  • the extension direction has different adhesive properties or is composed of strips which have such different adhesive properties.
  • both strips preferably extend in the longitudinal direction and, more preferably, these strips are also parallel to one another.
  • the first strip is formed by the base support or its material.
  • this first strip can be formed by a coating of or an order on the base support (s).
  • the second strip may be formed in different ways.
  • the second strip may be formed by a glued to the base support or by a glued to the base support member.
  • the second strip can also be formed by a coating arranged on (or on) the base carrier, in particular but not exclusively a self-adhesive coating.
  • strip used in the context of this application is in particular geometrical to be understood as a portion of the sealing strip, which extends in the longitudinal direction of the sealing strip, but may extend in the direction perpendicular to the longitudinal direction of the sealing strip width direction across the entire width, but may advantageously extend over only a portion of this width ,
  • the two first surfaces preferably have the same direction, that is to say they are oriented upward, for example, when the band is viewed.
  • the two second surfaces are correspondingly in the other direction, i. at the same viewing of the tape down.
  • the first two surfaces are also on the same side of the carrier.
  • the first surfaces merge into one another.
  • this transition may be a transition that forms a sharp boundary between the two surfaces or that is formed along a line and / or that a first surface directly adjoins the other first surface.
  • the second surfaces also merge into one another or a second surface adjoins the other second surface.
  • the number of layers and / or layers arranged on one another differ in the different sections or strips.
  • only one layer may be provided in the first strip, which is formed for example by the base support itself.
  • the second strip may also be provided several layers, such as two layers, such as in the form of an adhesive strip, which is formed on the base support.
  • three layers may be provided, such as when two adhesive strips are glued to the base support.
  • the number of layers may change, such as when adhesive strips are adhered to an edge of the base support.
  • At least one of the surfaces of at least the second strip has an adhesive coating.
  • the adhesives used may be different adhesives, such as hot melt adhesives, acrylate adhesives, and the like.
  • at least in some areas of at least one surface no liner is present. So it is possible that some defined self-adhesive in the product, a liner or a cover layer in the delivery state is no longer available.
  • At least one adhesive coating of the second strip has a continuous adhesive layer.
  • at least one adhesive coating of at least one strip and in particular the second strip has an adhesion strength (to steel, according to Afera 4001, measured at 23 ° C and a tensile speed of 300mm / min), which between 10N / 25mm and 45N / 25mm, preferably between 10N / 25mm and 35N / mm and more preferably between 12N / 25mm.
  • the first strip is formed essentially by the base carrier.
  • the base carrier preferably also has opposing surfaces with different physical properties.
  • the base support is coated on a surface or side.
  • the base support is provided on this surface with a non-stick coating.
  • the base support extends along the entire width.
  • the second strip is glued to the base support.

  • an adhesive layer is arranged over the entire surface of the nonwoven element.
  • the second strip is coated on both sides with adhesive or double-sided with an adhesive layer. It is possible that this second strip has the same adhesive strengths on its surfaces, but it would also be conceivable that the adhesive strengths differ from each other. It would also be possible for the adhesives on the respective surfaces to be optimized for different materials to which the sealing tape is to be attached. In other words, the second strip preferably has an adhesive element on both surfaces. Furthermore, it is also possible for a masking tape, in particular a liner, to be arranged on one side of the adhesive strip.
  • the sealing tape has a thickness (defined in a direction perpendicular to the longitudinal direction and the width direction) which is less than 4 cm, preferably less than 3 cm, preferably less than 2 cm, preferably less than 1 cm, preferably less than 0.5cm and more preferably less than 0.3cm.

  • the adhesive tape can be unrolled in another way, so that first the above-mentioned second surface is exposed and this second surface is pressed against the building. Subsequently, the cover can be deducted from the first surface. In this way, depending on the installation situation, either one of the two adhesive surfaces can be exposed first. More precisely, only the cover element can be withdrawn from a sealing tape roll for this purpose, and that is to be deducted preferably exactly by one winding of the sealing tape. If the rolled-up sealing strip continues to be unwound from this position, the cover element will be located on the opposite surface.
  • the adhesive strengths of the two surfaces on which the cover is arranged in a similar size are made similar.
  • These adhesive strengths preferably differ by less than 40%, preferably by less than 30%, preferably by less than 20%. In this way, it can be determined by the user from which of the two surfaces the cover element should first be deducted.
