Abstract: Layer constructions allow an adhesive tape to be wound to form a spool simply and with relatively uncomplicated apparatus. At least one layered construction comprises: an adhesive tape comprising at least one outer layer of pressure-sensitive adhesive; a release liner lying on the outer layer of pressure-sensitive adhesive; and an interliner lying on the side of the adhesive tape opposite the outer layer of pressure-sensitive adhesive, at least the side of the interliner facing away from the adhesive tape being adhesively furnished, wherein all layers of the layered construction finish substantially flush with respect to each other. At least one spool comprising a spool core and the at least one layered construction wound crosswise in a plurality of plies on said core, and a method for producing the at least one spool are also disclosed.

Abstract: Provided are methods for adhesively bonding profiles to substrate surface. An example method includes plasma-treating each of a profile surface and a first adhesive side of a layer of pressure sensitive adhesive. The pressure sensitive adhesive includes a) 40 to 70 wt %, based on the total weight of the pressure sensitive adhesive, of at least one poly(meth)acrylate; b) 15 to 50 wt %, based on the total weight of the pressure sensitive adhesive, of at least one synthetic rubber; and c) at least one tackifier compatible with the poly(meth)acrylate(s). The method further includes bonding the profile surface and the first adhesive side to one another, plasma-treating a second adhesive side of the layer of the pressure sensitive adhesive, and bonding the plasma-treated second adhesive side to the substrate surface.

Abstract: The aim is to provide an efficient method for producing a multi-layer adhesive tape having a heat-sealing layer and a pressure sensitive adhesive that results in effective composite adhesion of the individual layers to one another. This is accomplished with a method for producing an adhesive sealing tape covered with a release liner, said method comprising a) heating a pressure-sensitive adhesive in such a way that the pressure-sensitive adhesive is present as a melt; and b) producing a composite in a roll nip in such a way that a hotmelt adhesive layer is lying on one roll, a release liner is lying on the other roll, the release liner having an outer release layer, and this outer release layer pointing away from the roll surface, the pressure-sensitive adhesive melt is introduced into the roll nip and by rotation of the rolls, contacting of the layers and cooling, a composite is obtained with the sequence of hotmelt adhesive layer—pressure-sensitive adhesive—release liner, the release liner remaining on the pressure-sensitive adhesive until the adhesive tape is applied.
