An assembly for forming a structural, insulating or decorative article as any of a roll, sheet, board or panel and including a width extending die and extruding nozzle for issuing a flowable polymeric material having either of a solid or ribbed cross sectional profile and including any of a polyurethane, a polypropylene or any other polymeric material. At least a pair of opposing and rotating pinch rollers are arranged for receiving therebetween the flowable material. A material roll simultaneously feeds a material layer between the rollers and against the flowable polymer material at a given pressure to cause the polymeric material to fuse and embed within the material layer. The material separate material layer can further include any structural panel, multi-panel or pallet style construction, such including both solid and interiorly hollowed/corrugated constructions.

A multi-layer visor system for a surgical hood or garment is provided. The system includes a base film layer and one or more removable film layers that are coextruded at high temperature to form a sterile surface between each of the film layers should the surgeon elect to peel away a soiled or splattered removable film layer during the course of a surgical procedure so that an unobstructed view can be maintained. Thus, no separate sterilization step is required in order to sterilize the layers of the visor system. Each of the removable film layers can additionally include a tab having distinctive features in order to enable a wearer to easily distinguish between the tabs in order to make it easier for a wearer to know which tab to pull first to remove the outermost removable film layer. Further, because the tabs are located about the perimeter of the removable films, viewing is not obscured, yet the film layers are held securely in place until easily removed from the underlying removable film layer or base film layer.

A method for forming a multi-layer packaging laminate including the following steps in the mentioned order: i) providing a polyolefin film as a base layer of the laminate, wherein the base layer forms a first outer most polymer surface of the laminate, ii) applying a first polymer layer arrangement in a flowable state onto the base layer at a first application station, the first polymer layer arrangement having at least one polymer layer, iii) transporting the base layer with the applied first polymer layer arrangement to a further application station, iv) applying a second polymer layer arrangement onto the first polymer layer arrangement at the further application station, the second polymer layer arrangement having at least one polymer layer, wherein the second polymer layer arrangement forms a second outermost polymer surface of the laminate, wherein at least one of the first and the second polymer layer arrangement contains a water vapor and/or oxygen transmission polymer barrier layer, wherein the second polymer layer arrangement is applied to the first polymer layer arrangement in a flowable state.

Reinforced microporous polyolefin sheets comprise one or more layers of a microporous polyolefin and a non-woven fabric at least partially embedded in the microporous polyolefin. The reinforced microporous polyolefin sheet is made in an extrusion lamination process by which a polyolefin sheet and non-woven fabric are laminated, followed by sequential cold and hot stretching steps to produce the micropores.

An assembly for creating any structural, insulation or decorative article. A plank shaped body is continuously fed through a cross sectional extrusion die for coating at least an exterior of said body with a polymer material. The plastic extrusion formed along opposite side edges of the extruded body can also form interlocking profiles which facilitate edge-to-edge assembly of the completed articles in such as a wallboard, ceiling board or floorboard assembly. Pinch rollers are provided for compressing outer layers of material to the outer polymer coating and are not limited to any of burlap, muslin or canvas, as well as other outer materials like organic/inorganic acoustic dampening materials along with vinyl fabrics which can include both an exterior finished side and an opposite natural side for facilitating adhering to the central extruded polymerized material.

Provided are: a method and apparatus for manufacturing a highly permeable elastic sheet; a method and apparatus for manufacturing a highly gas-permeable stretchable composite sheet; and a highly gas-permeable stretchable composite sheet. An elastic resin material containing a thermoplastic elastic resin as a main component is melted by being heated to a temperature higher than a temperature range in which the elastic resin material is elastically deformed, the molten elastic resin material is discharged in a fibrous or linear form, the discharged elastic resin material (intermediate) is applied in a net shape onto a cooling member, the applied elastic resin material is cooled by the cooling member to the temperature region in which the elastic resin material is elastically deformed, and the applied elastic resin material is solidified to obtain an elastic sheet. The elastic sheet and non-woven fabrics are stacked and joined to obtain a stretchable composite sheet.

A method of producing an elastic profile with longitudinally recurring transverse protrusions includes extruding a primary profile at a primary extruder; extruding a secondary profile at a secondary extruder, the secondary profile includes a substrate layer and transverse protrusions, the secondary extruder includes an extrusion die, wherein a rotating molding wheel forms a wall of the extrusion die, the molding wheel having recesses functioning as molds for the transverse protrusions within the extrusion die; joining the primary profile and the substrate layer of the secondary profile at a joining point for fusion bonding forming a composite structure. A rotating pressing wheel, may press on the composite structure against a bedding separate from the molding wheel. The primary profile may travel along an entirely straight path from the primary extruder to the joining point. The joining occurs at a nip formed between the molding wheel and a flat and stationary bedding.

This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).

A method of making a fiber preform for ceramic matrix composite (CMC) fabrication comprises laminating an arrangement of fibers between polymer sheets comprising an organic polymer, which may function as a fugitive binder during fabrication, to form a flexible prepreg sheet. A plurality of the flexible prepreg sheets are laid up in a predetermined geometry to form a stack, and the stack is heated to soften the organic polymer and bond together the flexible prepreg sheets into a bonded prepreg structure. Upon cooling of the bonded prepreg structure, a rigid preform is formed. The rigid preform is heated at a sufficient temperature to pyrolyze the organic polymer. Thus, a porous preform that may undergo further processing into a CMC is formed.
