Abstract: A composite oven gasket includes a flexible hollow tubular member braided from a number of glass fiber yarn ends and a lesser number of wire ends and a plurality of separate, individual clip fasteners extending though the tubular members and captured only by the yarn and wire ends defining the tubular body. At least forty-four yarn and wire ends are used in the tubular members and less than twenty percent of the ends are wire.

Abstract: A gasket-like device includes an elongated core, an outer jacket of glass fiber yarns, woven, preferably braided, entirely around and along the core. Each of the glass fiber yarns has an outer surface exposed to view with a polymeric resin coating in an amount sufficient to at least cover essentially all of an outer surface of each yarn exposed on the device and insufficient to obscure the plurality of individual glass fiber yarns from one another in the outer jacket. The outer covering may be coated with a colored polymeric resin to produce a desired exterior color. In a described embodiment for self-cleaning ovens, a plurality of individual fasteners are spaced along the device. Each fastener includes a base captured within the outer jacket and an engagement portion extending outwardly from the base through the outer jacket. A method of manufacturing and coloring the gasket-like device is also disclosed.

Abstract: A improvement to a gasket that includes an elongated seamless tubular member formed from at least a plurality of interwoven glass fiber yarn ends and a plurality of spring clip fasteners spaced along the tubular member, each fastener including a base located within the tubular member and an engagement portion extending outwardly through the tubular member away from the base. The free ends of the tubular member are coupled together at a joint so that the elongated tubular member forms a closed loop. A second tubular member is positioned around the joint, concealing the joint. The second tubular member may include one or more fasteners each having a base located between the elongated tubular member and the second tubular member and an engagement portion extending outwardly through the second tubular member away from the elongated tubular member. The second tubular member may be composed of at least a second plurality of glass fiber yarns interwoven together or a corrugated metal tube.

Abstract: Improved spring fasteners are formed from a single length of at least partially hardened wire bent to form a generally planar base and a generally diamond-shape engagement portion or dart extending generally perpendicularly from the center of the base. The length of wire is bent at its center to form the dart. Free ends of the wires are crossed past and partially around one another to provide a scissor action to arms forming either side of the dart. The free end portions of the wire are extended away from the dart in opposite directions. Each is curled into a circular loop in which the extreme end of the wire is overlapped or butted with an intermediate portion of the wire to form a fully closed loop at either end of the base. The configurations are actually less compact than previous configurations and, as a result, is less likely to nest with identical fasteners.

Abstract: Thermally insulative sleeves include a seamless, hollow, flexibly resilient inner tubular member woven of strand material including at least one metal wire strand, a separate, integral, at least essentially unbroken, metal surface member applied over the inner tubular member extending along and at least essentially completely surrounding the inner tubular member and a flexible outer cover also woven of strand material extending along and completely around the inner tubular member and metal surfaced member securing the metal surface member with the inner tubular member and offering some degree of protection. The inner tubular member may be knit from wire or from a combination of wire and glass fiber yarn, the latter providing some thermal insulative protection. The metal surfaced member may be foil or some other metal covered composite or laminate material sufficiently thin and pliable so as to be deformable by the inner member.

Abstract: A gasket-like device includes an elongated core, an outer jacket woven, preferably braided entirely around and along the core, and a plurality of individual fasteners spaced along the device. Each fastener includes a base captured between adjoining portions of the core and the outer jacket and an engagement portion extending outwardly from the base through the outer jacket. An outer covering of a plastic polymeric material or other material may be provided, if desired, around and along part of all of the outer jacket.

Abstract: A gasket assembly is made by securing together in a flexible, elongated gasket subassembly, a first, elongated, flexible tube of braided glass fiber and an adjoining, flexible, second, elongated knit wire mesh tube member by sewing together the first tube and the second tube member. Braid of the first tube permits elongation of that tube under tension. The adjoining tubes are secured together along their lengths in states of elongation such that the second tube member is fully elongated under tension, to the extent permitted by its metal wire fabric, before the first tube is stretched to a maximum elongation permitted by the braid. The resulting elongated flexible assembly is threaded onto an elongated, substantially rigid frame member, preferably by threading the frame member through a sleeve formed in the knit wire mesh tube member by the stitching.

Abstract: Flexible, composite tubular devices of the present invention include a flexible plastic tube and a reinforcing flexible, tubular member at least substantially embedded in the tube, the member having an outer side, an inner side opposing the outer side and surrounding a hollow interior of the member, and a multiplicity of macroscopic pores substantially uniformly distributed around and along the member and extending through the tubular member between the outer and inner sides before the tubular member is incorporated into the composite tubular device of the invention, and the plastic of the tube extending through the pores between the inner and outer sides of the tubular members.

Abstract: A welding backup tape assembly includes a flexible, elongated, heat resistant ribbon, such as a metal foil strip, with a flexible, elongated, heat resistant, fibrous rope having a flexible reinforcing core, preferably metallic, attached to one major side of the ribbon, suggestedly by stitching with a glass fiber thread, to form a substantially unitary assembly. Pressure sensitive adhesive layers are applied to the ribbon on either side of the fibrous rope to allow that side of the assembly to be adhered to the weldable workpiece. In the preferred embodiment, the fibrous rope is formed by a knitted, multistrand stainless steel wire core supporting a sheath of knitted, texturized, untwisted fiberglass yarns. Untexturized, low or no twist, continuous, glass fiber thread is used to stitch the rope to the ribbon.

Abstract: A composite bulky fabric of narrow width having lengthwise extensibility and widthwise dimensional stability in which the fabric is made up of a plurality of flattened tubular-knit components disposed in edge-to-edge juxtaposed position and interconnected by seams extending along the junction and formed of a zigzag line of stitching, the knitted tubular components being formed of a non-run stitch comparable to a tricot stitch formation. The tubular knit components are preferably knit on a small diameter knitting machine having a reciprocating feed for each of the needles so that the feed reciprocates between a pair of adjacent needles, and is supplied from a creel or other stationary supply.The products made in accordance with the invention are useful for thermal and electrical insulating, gasketing, padding, sealing and similar purposes.The novel method for producing the fabric is diagrammed in FIG. 6.
