A splice tape for joining two pavement tapes in an end-to-end manner comprises a first adhesive layer; and a reinforcing layer disposed on one major surface of the adhesive layer, wherein the first adhesive layer is capable of adhering to a concrete or asphalt surface, wherein the reinforcing layer adheres to a first adhesive portion of a first pavement tape and to a second adhesive portion of the second adhesive tape when deployed.

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.

The invention aims to provide automatic packaging film and a method for preparing the same. Mutually parallel adhesive areas (2) are arranged at intervals laterally on the same side of the film substrate, a non-adhesive area (1) is formed between two adhesive areas (2), and each non-adhesive area (1) and an adjacent adhesive area (2) form a packaging section; between the adjacent packaging sections, the non-adhesive area (1) of a packaging section and the adhesive area (2) of a next packaging section are connected through a separable splicing tape; all the packaging sections are connected through separable splicing tapes to form an entire continuous automatic packaging film (3). The invention solves the technical problems that the film is stuck or broken during automatic packaging, leading to machine shutdown and thus failure of automatic packaging.

The invention relates to an adhesive piece for the adhesive connection of material webs. The adhesive piece comprises an adhesive compound carrier which bears adhesive compound on two opposite sides, and at least one release liner which originally covers, at least in certain regions, the adhesive compound carrier and also the adhesive compound present there, protrudes at least in certain regions beyond the adhesive compound carrier, and is removable by a release liner removal apparatus.

The invention relates to a release liner removal apparatus, comprising at least one release liner removal device for removing at least one release liner from at least one adhesive piece arranged on a material web, at least one support body which supports the at least one release liner removal device, and at least one guide body which is arranged adjacent to the at least one release liner removal device at least during the removal of the at least one release liner and which serves for guiding the material web.

The invention relates to a material web drawing-in apparatus for drawing in a material web. The material web drawing-in apparatus comprises at least one material web holding device for holding the material web to be drawn in, and at least one guide for guiding the at least one material web holding device from a material web drawing-in point to a material web transfer point, and also at least one drawing-in drive which is in connection with the at least one material web holding device and which serves for displacing the at least one material web holding device along the at least one guide upon drawing in the material web to be drawn in in the direction of the material web transfer point.

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.

The invention relates to an adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where the film is a biaxially oriented film made of polypropylene, polyethylene or polyester such as PET, and on the side of the carrier not coated with adhesive there is a release layer, based in particular on carbamate.

The present invention relates to a band-like joint tape for covering a butting portion formed by butting an end portion of a one packing film to an end portion of another packing film and connecting the respective end portions of these packing films to each other. The joint tape is comprised of a laminate film formed by adhering a joint layer to a support layer at a peelable state, and covered so as to face the joint portion. to the butting portion and heat-sealed so that the joint layer is fused to the butting portion and the fused portion of the joint layer is peeled off from the support layer.

A screen splicing structure is provided. The screen splicing structure includes a substrate layer, a middle adhesive layer, and a surface layer. The substrate layer includes a first substrate and a second substrate. The second substrate is spliced with the first substrate, and a seam is formed at a splicing place. The surface layer and the middle adhesive layer are stacked. The surface layer covers the seam by bonding the middle adhesive layer and the substrate layer. The peeling strength of the surface layer and the substrate layer is greater than or equal to 1,000 gf/inch. A method for forming the screen splicing structure is also provided.
