Described is a venting device including a flexible outer covering defining an outer surface and an inner surface, a set of helicoidal venting strips, and a set of helicoidal buffers. The outer covering has a first end and a second end and a longitudinal axis therebetween. Each venting strip is anchored to the inner surface and extends substantially between the first end and the second end and the set of venting strips is arranged substantially helicoidal and defines a set of helicoidal seams therebetween. The set of helicoidal buffers includes a buffer covering an inner opening of each seam of the set of helicoidal seams where each buffer is configured to shield the inner opening of the corresponding seam from penetration and each buffer is anchored to at least one of the outer covering and a neighbouring venting strip of the set of venting strips.

According to some illustrative embodiments, a protective product is provided that includes: at least one expandable slit paper sheet, said at least on expandable slit paper being expanded between opposing ends of said slit paper; a first embossed paper sheet facing said expanded slit paper sheet and a second paper sheet facing an opposite side of said at least one expanded slit paper sheet, at least one of said first embossed paper sheet and said second paper sheet being fixed to said expanded slit paper sheet at the opposing ends of said expanded slit paper sheet and thereby maintaining said expanded paper in its expanded state, said first embossed paper sheet having a plurality of embossings that increase the rigidity of said embossed paper sheet, whereby inhibiting deformation of said embossed paper sheet that is fixed to said expanded slit sheet paper.

A void between two or more composite laminate parts is filled by a composite laminate filler that is laid up and integral with at least one of the parts.

A method of making an elastic composite is described that entails conveying a first sheet of material on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the first sheets. A second sheet of material is applied onto the first sheet having elastics applied thereon, thereby creating a subcomposite including the first sheet, the second sheet, and elastics sandwiched therebetween, wherein a plurality of elastics extend outward from the one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite. The sub-composite is cut through the first and second sheets and the elastics, thereby separating the sub-composite into a first carrier and a second carrier, each carrier including a first material layer and a second material layer, whereby a plurality of spaced apart elastic elements extend from the first carrier to the second carrier, the first and second carriers defining an exposed elastic region therebetween formed by the plurality of spaced apart elastic elements.

A multilayered polymer composite film includes a first polymer material forming a polymer matrix and a second polymer material coextruded with the first polymer material. The second polymer material forms a plurality of fibers embedded within the polymer matrix. The fibers have a rectangular cross-section.

An article comprising: a carrier (12), activatable material (14) disposed on the carrier, one or more carrier extensions (16) extending from the carrier; wherein the article is adapted to provide sealing, baffling, or reinforcement within a structure's cavity.

The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

A gummed paper includes: a first adhesive layer, configured to adhere to an object; a first substrate, adhered to a surface of the first adhesive layer opposite to the object; a second adhesive layer, adhered to a surface of the first substrate opposite to the first adhesive layer; a second substrate, adhered to a surface of the second adhesive layer opposite to the first substrate; and a plurality of foaming agent particles, distributed in the first adhesive layer.

A roofing shingle includes an overlay sheet, an underlay sheet, and a reinforcement member. The overlay sheet includes a headlap portion and a tab portion, wherein the overlay sheet has an overlay sheet height. The underlay sheet is secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. The reinforcement material is secured to a top surface of the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.

A glass roll includes at least one glass film and one intermediate material one on top of the other in at least two layers onto a winding core. The glass film layers are held in place by the intermediate material layers. The glass roll is produced with a method including provision of a glass film, a winding core and a compressible intermediate material. At least one inside layer of the intermediate material is wound onto the winding core. The glass film and the intermediate material are wound onto the winding core in such a manner that the glass film is wound onto the winding core in alternating layers with the intermediate material. The intermediate material and/or the glass film is wound at a tensile stress acting in a longitudinal direction which causes a compression of the intermediate material and holds the glass film end in place on the glass roll.
