The invention relates to a plant having at least one material roll preparation arrangement for bringing a material roll carrying a material web to be drawn in into a defined initial situation, and having at least one material web working/processing arrangement, in particular material web dispensing arrangement, in particular material web unrolling arrangement, in particular material web splicing arrangement, which material web working/processing arrangement is capable, owing to the defined initial situation of the material roll, of receiving the material roll in automated fashion and preferably receiving the material web in automated fashion and/or preparing the material web in automated fashion.

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.

An apparatus and method for assembling, dispensing and using a laminated paper web transfer tape, an embodiment of the apparatus having a pair of transfer tape spools enclosed within a cartridge dispenser, one transfer tape spool containing a first tape component of the laminated transfer tape and the other transfer tape spool containing a second tape component of the laminated transfer tape, the first tape component being the combination of a substrate having adhesive on both sides and a release liner, the second tape component being a cover flap member having a release coating over at least a majority of one side. The components are unwound from the spools and pressed together such that they become joined along a longitudinal edge strip, then dispensed from the housing. The cover flap member covers one of the adhesive sides of the transfer tape substrate until the moment just prior to transfer of a continuous paper web from a full web spool to an empty web spool, the cover flap member being opened to expose the adhesive by air pressure or resistance. The cartridge dispenser is removed retained within a dispenser frame.

Subject matter of the invention is an adhesive tape (K) for on-the-fly roll changeover of flat web material (RB) wound up into rolls (R; B), having a carrier layer (K3), which comprises a first surface (K31) and a second surface (K32) opposite the first surface (K31), a first layer of adhesive (K1), which is disposed indirectly or directly over at least part of the area on the first surface (K31) of the carrier layer (K3), a second layer of adhesive (K2), which is disposed on at least one areal region (FB) of the second surface (K32) of the carrier layer (K3), and at least one predetermined breakage area for the areal splitting of the adhesive tape (K), where the predetermined breakage area is configured such that the at least one areal region (FB) comprises a surface coating (K4), which is disposed between the carrier layer (K3) and the second layer of adhesive (K2), where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of adhesion of the surface coating (K4) to the carrier layer (K3), and/or where the forces of adhesion of the second layer of adhesive (K2) to the surface coating (K4) are greater than the forces of cohesion within the surface coating (K4), wherein the second layer of adhesive (K2) has a deactivated bonding region (K6) on a surface (K21) pointing in the carrier layer (K3) direction.

Provided are adhesive tapes and methods of use. The adhesive tape provides a flying splice of fibrous materials. An example adhesive tape comprises an adhesive layer, a backing adjacent to the adhesive layer, and a non-adhesive mechanical fastener.

Adhesive tapes and methods for splicing low surface energy substrates with flying splices are provided. An example adhesive tape comprises an adhesive layer and a backing adjacent to the adhesive layer. The adhesive layer comprises a first adhesive comprising a higher shear resistance, cohesive strength, and surface energy relative to a second adhesive, and the second adhesive comprises a higher tack for low surface energy substrates relative to the first adhesive. The second adhesive is different from the first adhesive. The second adhesive is adjacent to the first adhesive and there is substantially no overlap between the first adhesive and second adhesive.

Provided are adhesive tapes and methods of use. The adhesive tape provides a flying splice of fibrous materials. An example adhesive tape comprises an adhesive layer, a backing adjacent to the adhesive layer, and a non-adhesive mechanical fastener.

A splice tape is provided. The splice tape includes two internal support layers bonded at interface between opposing inner surfaces of the internal support layers. The support layers are formed utilizing a process and/or materials that ensure that the two internal support layers separate cleanly and consistently along the interface of the two internal support layers.
