A laminate sheet is formed from a lamination system that includes a sheet supply, a material supply, and a laminator. The laminator causes a sheet from the sheet supply to be laminated to a sheet from the material supply to establish the laminate sheet. The laminate sheet includes film strips and a web coupled to the film strips.

An assembly for producing cabinet doors including a CNC machine provided with a porous worktable, means for positioning workpieces thereon, means for applying a vacuum to such porous worktable for adhering such workpieces thereto and means for machining such workpieces adhered to such worktable; and means for thermally deforming a thermally pliable foil to laminate such workpiece.

A reinforced stretch film obtained by a method of producing a reinforced stretch film comprising the steps of: providing an elongated base sheet of plastic stretch film having a longitudinal axis, forming a plurality of cord-like, elongated reinforcement members and a plurality of plastic film strip overlays, positioning the plurality of elongated reinforcement members on the elongated base sheet, positioning a single plastic film strip overlay over each of the elongated reinforcement members, folding each edge of the elongated base sheet inward toward a center of the elongated base sheet to further strengthen and reinforce each edge and attaching the plastic film strip overlays and the folded edges to the cord-like, elongated reinforcement members and to the elongated base sheet to fixedly sandwich the cord-like, elongated reinforcement members between the elongated base sheet and the narrow plastic film strip overlays.

A lamination system includes a film supply, a non-woven material supply, and a laminator. The laminator causes a film from the film supply to be laminated to a sheet from the non-woven material supply to establish a laminated sheet.

A method of producing an optical panel assembly including the polarizing film in a continuous manner by laminating a polarizing film to a surface of a rectangular-shaped optical panel, is disclosed. The polarizing film is formed by performing a step of subjecting a laminate including a continuous web of a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to a 2-stage stretching consisting of a preliminary in-air stretching and an in-boric-acid-solution stretching, to reduce a thickness of the PVA type resin layer to 10 μm or less, and a step of causing a dichroic material to be absorbed in the PVA type resin layer.

A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.

Sheets of polymerized siloxane and related methods for providing insulation between an interior of an enclosure and outside of a window are disclosed. According to an aspect, a method includes providing a sheet of polymerized siloxane. The method also includes placing the sheet to at least substantially cover a pane of a window of an enclosure. Further, the method includes attaching the placed sheet to the window for providing insulation between an interior of the enclosure and outside of the window.

A fiber placement head assembly for applying a plurality of composite tape segments on a mold that includes a fiber placement head configured to receive composite tape from a composite tape source and apply the composite tape to the mold. The assembly also includes one or more air-operating conveyors, coupled with the fiber placement head, each having an inlet that is configured to receive an end of composite tape from the composite tape source, an outlet configured to provide the end of composite tape to the fiber placement head, and one or more inline vacuum conveyors that are configured to receive compressed fluid from a source and direct the compressed fluid toward the outlet thereby transporting the end of the composite tape from the inlet to the outlet and into the fiber placement head.

There is disclosed a composite material lay-up head (20) for applying elongate fibre reinforcement material (14) to a tool (12), the head (20) comprising: at least one elongate tow guide channel (32) for guiding fibre reinforcement material (14) from a tow inlet (33) to a tow outlet (35) of the channel (32); and feed apparatus (36, 38) for feeding fibre reinforcement material through the at least one channel (32); wherein the or each channel (32) is provided with at least one nozzle (60) arranged so that in use a jet of gas can be delivered into the channel (32) so as to inhibit contact between fibre reinforcement material (14) in the channel (32) and the channel (32).
