An adhesive tape that provides a unique easy end locator which enables the user to find the terminal end of a tape. The adhesive tape is formed of multiple segments, where each segment includes a backing material that is the carrier of an adhesive layer, with perforations defined transversely across the longitudinal length of the backing to define multiple segments. Each segment has a unique, effortless end locator, a small area free of adhesive, located at the beginning of each segment, being an integral part of the backing material. The perforations may be made at predetermined length between a preceding segment and a subsequent. The predetermined length may be a uniform length. The final product may be carried on a core and formed into a roll. The tape can be used in fields where a predetermined length is desired. The lengths of multiple tapes can cover unlimited areas of use.

The subject matter of the present invention is a method and a device for producing an adhesive tape (1). First a material web (2) comprising a carrier tape material is supplied from an unwinding unit (3). The supplied material web (2) is subsequently provided on at least one surface with at least one adhesive strip (4) in a coating unit (6). The material web (2) provided with the adhesive strip (4) is then cut into at least two longitudinal strips with the aid of a cutting device (10) and made up into individual adhesive tapes (1). According to the invention, a sensor (8, 9) scanning the material web is used to align the material web (2) and/or the cutting device (10) in the transverse direction (Q) in such a way that a longitudinal cut (S) respectively produced with the aid of the cutting device (10) is introduced in an exact position into the material web (2).

A sealing device including a waterproofing membrane, a sealant layer covering at least a portion of the second primary exterior surface of the waterproofing membrane and an adhesive layer covering a portion of the outer major surface of the sealant layer facing away from the second primary exterior surface of the waterproofing membrane, wherein the sealant layer is composed of an adhesive sealant composition comprising at least one elastomer, at least one at 25° C. liquid polyolefin resin, and at least one inert mineral filler. A method produces a sealing device, a method waterproofs a substrate, and a waterproofed substrate.

A temporary surface masking film is provided with an adhesive tape that faces outwardly, thereby dramatically improving the process of application. At least the film may be transparent or translucent and the film may be accordion-folded onto the roll. The width of the film may be in the range of 1 to 12 feet. The roll may be retained in a plastic carrier, with a serrated edge for cutting the film. The roll may be coupled to an axial handle, and the roll and handle are provided in a plastic carrier. A method includes adhering a portion of the outwardly facing adhesive tape to a surface to be protected. The film is then unrolled such that it unfolds, hangs down and clings to the surface. The film may then be cut when the surface to be protected is sufficiently covered. Conveniently, the inventive film may be applied by a single user.

A channeled seam tape includes a liquid permeable facer sheet attached to an adhesive portion, where the adhesive portion defines a channeled portion. A removable liner covers the adhesive portion and can be removed to press the tape onto a pair of adjacent substrate surfaces. Once the tape has been pressed onto the substrate surfaces, the adhesive portion covers a gap located between the substrate surfaces and adheres to each substrate surface.

A method of applying an adhesive to a non-planar surface. The method includes providing a segmented film adhesive. The segmented film adhesive comprises: (i) a liner; and (ii) an adhesive layer on the liner, the adhesive layer comprising a plurality of contiguous, discrete adhesive segments. The segmented film adhesive is positioned on a non-planar surface of a first adherend so that a first portion of the discrete adhesive segments are in contact with the non-planar surface and a second portion of the discrete adhesive segments are not in contact with the non-planar surface. The liner is removed from the non-planar surface, wherein only the first portion of the discrete adhesive segments remain on the non-planar surface of the first adherend.

A tape is provided having a long shape in which a bond portion is formed on at least one surface. The tape includes a first slit row including a plurality of slits formed intermittently along a longitudinal direction, and a second slit row including a plurality of slits formed intermittently along a longitudinal direction and parallel to the first slit row. A portion without having a slit formed in the first slit row is arranged so as not to overlap a portion without having a slit formed in the second slit row.

A label and liner assembly comprises one or more labels, the label(s) including a facestock and an adhesive layer on a surface of the facestock. A support liner is releasably adhered to the adhesive layer, the support liner defining a plurality of embossings projecting from a surface of the support liner toward or away from the label. A transfer tape and a method for assembling label material are also provided.

Disclosed are methods manufacturing a four-layer membrane electrode assembly integrated with an adhesive film. The methods include a step of preparing a three-layer membrane electrode assembly comprising a first electrode and a second electrode by attaching the first electrode to a first surface of an electrolyte membrane, attaching the second electrode to a second surface of the electrolyte membrane, and joining a first gas diffusion layer to the first electrode; and a step of attaching an adhesive film to the three-layer membrane electrode assembly by preparing the adhesive film by attaching an upper protective film to an upper surface of the adhesive film and a lower protective film to a lower surface of the adhesive film, removing the lower protective film, and attaching the adhesive film to an outer peripheral region of the membrane electrode assembly including the second electrode.

An adherable film includes a substrate that is substantially free of a flame retardant material and has a top major surface and a bottom major surface. An adhesive layer disposed on the bottom major surface of the substrate has a continuous pattern. The adhesive layer is made of an adhesive that is substantially free of a flame retardant material. In a plan view, the continuous pattern defines a plurality of discontinuous non-adhesive portions of the substrate without the adhesive. Each discontinuous non-adhesive portion is completely surrounded by the continuous pattern. The adherable film including the adhesive layer having the continuous pattern exhibits an improved flame retarding characteristic relative to a discontinuous adherable film having a substrate with a same material composition as that of the substrate of the adherable film and a discontinuous adhesive layer with a same material composition as that of the adhesive layer of the adherable film.
