The film has a unitary structure and is comprised of an acrylic polymer/fluoropolymer composition which has a composition gradient across its thickness such that one surface of the film is fluoropolymer-rich to provide excellent weatherability, stain resistance and dirt repellant properties, while the opposite surface of the film is acrylic polymer-rich to give it self-bonding characteristics.

Abstract: A protective film is placed on acrylic sheet. The film has a polyethylene side and an adherent EVA side; it will survive stressful lamination procedures as well as thermoforming, and can be easily removed from a finished article after thermoforming.

Abstract: A printed surface covering which can be continuously manufactured by the following steps: utilizing a process printing method, a design is printed onto a polymer web having an opaque, uniform background color; this web is laminated onto a vinyl base web to form a composite material; this composite material is laminated to a wear resistant layer which is embossed in register with the printed design; and the embossed composite material is cut into discrete sections in register with the printed design.

Abstract: A laminated web is used for supplying characters, symbols or other shapes, which are cut from a layer of sign material comprising one of the layers of the web, subsequently adhesively attached to a supporting surface to create a sign. In the web the layer of sign material is superimposed on a layer of paper or similar material with an intervening layer of pressure sensitive or permanently tacky adhesive. A layer of dry adhesive is carried by the otherwise exposed face of the layer of sign material and is activatable into a tacky condition for adhesively attaching the underlying portions of the layer of sign material to a supporting surface. The arrangement of the layers, the types of adhesives and the bonding strengths of the adhesives to their adherent surfaces allow the shapes cut from the layer of sign material to be transferred to and adhesively attached to a supporting surface, after cutting, by a simple and easy process.

Abstract: An apparatus and method is provided for forming a textured pattern on a heated substrate. An extruder forms the heated substrate. A textured pattern is applied to a transfer sheet by rotary screening. Thereafter, contact is made between the textured pattern and the substrate for adhering the textured pattern to the substrate.

In a preferred application, the textured pattern formed on the substrate can be used as a vertical, horizontal or venetian blind.

Abstract: An improved process is disclosed for forming tiles that are embossed in register with a printed design. A printed design is first applied to a base coat and a wear coat is laminated over the design. Advantageously, the wear coat is applied to the printed web before it is heated for lamination. Before embossing occurs, the laminated product is cooled until partial setting occurs, and the embossing roll is sprayed with water in order to minimize the likelihood that the laminated product will adhere to the embossing roll. To avoid distorting the web during lamination and embossing, proper web tension is maintained by controlling the rotational speeds of the laminating drum and the embossing roll so that a desired ratio is preserved. The web is then cut into oversized tiles that shrink to size during annealing.

Abstract: A purpose of the disclosed method is to impart gathers and elasticity to a relatively inelastic film, membrane, or web substrate, through elastic banding with a viscoelastic hot melt pressure-sensitive adhesive (PSA). Typically, the resulting elastic-banded substrate product (e.g. 40) will be cut into discrete units and formed in to garments or body-encircling members such as disposable diapers. One step of the preferred method involves extruding a ribbon or band (13 or 113) comprising a viscoelastic hot melt PSA, which PSA has unusually high cohesion, stretchiness, and elasticity without excessive loss of adhesive bonding strength. (The viscoelastic behavior of the PSA is believed to be determined, at least in part, by the relative size of its crystalline domains and its rubbery domains and the glass transition temperatures and softening point of its components.

Abstract: The invention refers to a process of coloring (printing) of track-like objects (2), especially ski coverings of thermoplastics, such as olefins, especially high and low pressure polyethylene where, the layer is brought continuously as a hot foil, essentially in a state of fusion, in contact with a print carrier (3), on which there has been deposited a print pattern first of sublimation type and then of diffusion type dye stuff.

This allows the obtainment of warpage-free print patterns on relatively thin-walled track-like objects in a continuous process, where it is assured that no warpages occur after cooling or reheating of the printed layer.
