Abstract:
The invention relates to a splittable adhesive tape (1) with a left-hand (l) and a right-hand (r) delimiting edge, wherein at least one of these two edges (l, r) is unstraight. The unstraight edge (l) has projections (V), which are rounded at their furthest projecting points (v).
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:
The invention relates to a hand-held device 100 for unwinding an adhesive tape 41 which is located in the form of an Archimedean spiral on a roll 4 and has a double-sidedly adhesively furnished carrier, at least one of the two adhesive sides of the carrier being lined with a release material 42, consisting of a handle 1 which is disposed on a retaining plate 2, a holder 21, mounted rotatably on the retaining plate 2, for the roll 4 of the adhesive tape 41, a take-off apparatus 22, connected to the retaining plate 2, and more particularly in the form of a roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 22, and the adhesive tape 41 is taken off from the roll 4 during the dispensing operation, a take-off apparatus 23, connected to the retaining plate 2, and more particularly in the form of a roller, via which the adhesive tape 41 is guided such that the release material 42 is in direct contact with the take-off apparatus 23, and the release material 42 is taken off from the adhesive tape 42 during the dispensing operation, a contact roll 24, mounted rotatably on the retaining plate 2, which during the dispensing operation brings the adhesive tape 41 into contact with the substrate, and a release material accommodation roll 25, mounted rotatably on the retaining plate 2, which accommodates the release material 42 after it has been taken off from the adhesive tape 41, and which is non-positively connected to the holder 21, so that movement of the holder 21 sets the release material accommodation roll 25 in rotation.
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 comprising at least a) polyisobutylene and b) at least one tackifying resin, c) the molecular weight distribution of the polyisobutylene having two relative maxima, specifically d) one between 50,000 and 200,000 g/mol and e) a second between 1.0×106 and 3.5×106 g/mol.

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.
