Textiles are re-cycled by grinding and scatter-laying onto a needle-punched web optionally containing low-melting material, followed by laying a second needle-punched web over the scattered layer and re-needling the three layers before applying heat or heat and pressure to activate the low-melting ground material present within the layers. Additional low-melt ground material is optionally blended into the ground textile if low melt components are absent or insufficient to bond the composite. The ground material is driven and dispersed into the surrounding web layers with at least part of the material being adjacent the two outer surfaces. The physical properties of the composite can be adjusted by selecting suitable combinations including but not limited to needling stroke depth, needling density, needle gage, low-melt content, heat finishing conditions, and relative layer weights. The final composites can optionally be reintroduced into the original end use and include significant percentages of recycled material.

A sheet material (1) consisting of an mixture consisting essentially of: a) 10-50 percent by weight of random-oriented fibres, and; b) 90-50 percent by weight of a thermoplastic or thermoplastic elastomer; the weight percentages being based on the overall homogeneous mixture; and the sheet material having at room temperature a Shore D hardness of 40 to 85, preferably of 40 to 60, more preferably of 45 to 55. The sheet material (1) is used as a support in punching applications or as the top layer in punching belts (2).

A dissimilar material joined body is obtained by subjecting to electrical energizing under pressure and joining with electrodes a laminated member, which is of a structure in which a first plate-shaped part and a second plate-shaped part having a higher melting point than that of the first plate-shaped part are superimposed on each other. A concave portion having a shape corresponding to the outer shape of an electrode is formed on the surface of the first plate-shaped part on a side thereof opposite to the second plate-shaped part. The first plate-shaped part includes protrusions, which are inserted into through holes formed in the second plate-shaped part. A method of joining dissimilar materials includes a hole forming step, a stacking step, a pressure energizing step, and a solidification step.

The invention relates to a method for manufacturing a punched component comprising the steps: a) laminating a polymer film onto a metal sheet, b) subjecting the metal sheet to a punching process, by means of which the punched component is produced, wherein a polymer film is used which is provided with a cold-flowable pressure-sensitive adhesive.

A method of manufacturing a laminated steel plate capable of simplifying the manufacturing process. This is achieved by a method of manufacturing a laminated steel plate including a step of applying a mixture containing an oil and an adhesive composition for a laminated steel plate including at least one kind of a (meth)acrylate compound compatible with the oil and an organic peroxide to one side or both sides of a strip-like steel plate; and a step of punching a steel plate body from the strip-like steel plate with a punch portion of a press forming device, and laminating and bonding the steel plate bodies.

A structure comprising a composite laminate resin and fiberglass panel and method of manufacture thereof is provided.

There is described a method of creating a transparent polymer window (W) with a field of lenses (L) in a security paper substrate (1), the method comprising the steps of (i) providing a security paper substrate (1), (ii) forming an opening (10) into the security paper substrate (1), (iii) laminating a transparent film (5; 5*) onto a first side (I) of the security paper substrate (1) in such a way as to close the opening (10) at one end, and (iv) filling the opening (10) with transparent polymer material (2). In one embodiment, the transparent film (5) comprises a field of lenses (L) and is laminated onto the first side (I) of the security paper substrate (1) in such a way as to form lenses (L) on the first side (I) of the security paper substrate (1) in register with the opening (10). In another embodiment, the field of lenses (L) is replicated into the transparent polymer material (2) applied in the opening (10) in such a way as to form lenses (L) on a second side (II) of the security paper substrate (1), opposite to the first side (I), in register with the opening (10). Also described is a device designed to fill the opening (10) formed into the security paper substrate (1) with the transparent polymer material (2) and a processing machine comprising the same.

An adhesive skin patch with a support liner comprises at least a strip drug product and a release liner longer than the drug product. The support liner includes a backing film and an adhesive layer; the drug product is quadrilateral with two long sides being straight in parallel and two short sides each elliptical arcs convex outward; a longest interval between the two short sides is 20.0 mm or more and 50.0 mm or less, and an interval between the two long sides is 5.0 mm or more and 37.5 mm or less; and the elliptical arc has: an ellipse major axis of 20.0 mm or more and 50.0 mm or less, an ellipse minor axis of 14.8 mm or more and less than 50.0 mm, and the minor axis of at least 2.0 mm wider than the interval of the two long sides.

An acoustical panel apparatus includes a laminate panel substrate that is receptive to ink printing operations. The substrate may be provided with folding grooves to form an apertured base, a sidewall, and an inner wall which together define a receptacle. An acoustical tuning body is positionable at the receptacle to attenuate at least one of sound transmissions and sound reflections from sound passing through the apertures in the base. A mounting bracket is attached to the panel to secure the acoustical tuning body at the receptacle and for mounting the panel substrate to a wall or ceiling.
