Abstract: Adhesive tape for flying splices of flat web materials, in particular flat web materials with nonpolar surfaces, said adhesive tape at least comprising an upper self-adhesive compound layer, an inner adhesive tape area adapted as a flat predetermined breaking point, and a lower self-adhesive compound on the underside of the inner adhesive tape area, wherein a natural rubber adhesive compound is used as the self-adhesive compound for at least the upper self-adhesive compound layer, as well as methods for flying splices of flat web material wound onto rolls, in particular with nonpolar surfaces, using a corresponding adhesive tape.

Abstract: Adhesive tape for the on-the-fly roll changeover of flat web material wound up into rolls, comprising a carrier layer having a first surface and a second surface, a first layer of adhesive on the side of the first surface over at least part of the area, and a second layer of adhesive on one or more areas of the second surface, wherein the adhesive tape has regions suitable for areal splitting, at least those areal regions of the second surface on which the second layer of adhesive is provided being surface coated, the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of adhesion of the surface coating to the carrier layer, and/or the forces of adhesion of the lower layer of adhesive to the surface coating being greater than the forces of cohesion within the surface coating.

Abstract: An adhesive bonding system joins flat webs when changing rolls of such webs. The adhesive bonding system comprises two adhesive tape boundary edges, and further comprises a top carrier layer and a bottom carrier layer, a flat connecting element that connects the two carrier layers to one another and is suitable for opening the connection under the conditions of a static or flying roll change. At least one of the boundary edges of the connecting element does not extend in a straight line, and a straight-line emphasis line is defined in relation to this boundary edge, the emphasis line of this boundary edge extends along a preferential direction, and this boundary edge has a multiplicity of regions lying on one side of its emphasis line and also a multiplicity of regions lying on the other side of its emphasis line.

Abstract: A splicing adhesive tape having a first carrier and a first splittable connector element having a left and a right boundary edge, wherein at least one of said two edges is not straight and comprises protrusions that are round at the locations thereof protruding out the farthest, and a second splittable connector element having a left and a right boundary edge, wherein at least one of said two edges is straight, wherein the first and the second splittable connector element are disposed adjacent to each other on the carrier.

Abstract: The invention relates to a splittable adhesive tape with a left-hand and a right-hand delimiting edge, wherein at least one of these two edges is not straight. The edge that is not straight has rounded projections, which comprise blunt or flattened zones at their furthest-projecting points.

Abstract: An adhesive tape for flying splice, having a left and right boundary edge, at least one main carrier and a first layer of self-adhesive on the obverse of the main carrier, the reverse of the main carrier bearing a parting system suitable for effecting an adhesive bond to a substrate that can be parted again in such a way that sticky residues are left neither on the reverse of the main carrier nor on the substrate in the region of the parted bond, the parting system being constructed in the form of a multiply interrupted stripe having a plurality of segments that extends in the longitudinal direction of the adhesive tape, the individual segments having less of an extent in the longitudinal direction of the adhesive tape than the adhesive tape itself, and the parting system being suitable for effecting the parting process without the main carrier being damaged.

Abstract: An adhesive system for flying splice (“parting system”), suitable for producing an adhesive bond on a substrate that can be parted again in such a way that adhesive residues remain neither on the reverse of the adhesive tape nor on the substrate in the region of the parted adhesive bond.

Abstract: An adhesive tape for flying splice of flat web material which has been wound to form rolls, the adhesive tape having at least one carrier layer and a layer of adhesive, at least part of that surface of the carrier layer that faces that layer of adhesive being optically detectable, or optically detectable means being provided between the carrier layer and the layer of adhesive, and the layer of adhesive being designed such that the optical detection can be made through the layer of adhesive. The adhesive tape is modified such that its gloss value, i.e. the ratio of directed fraction and diffusely reflected fraction of the light stream incident on the surface, on the external surface of the layer of adhesive is reduced by at least 20% relative to an unmodified adhesive tape of otherwise identical construction.
