Abstract: Pile weatherstripping, which is clad with a wrapping of a film (14, 25, 104, 216) of flexible material, has one or more rows (19, 27, 100, 102, 212, 214) of pile (10, 24, 105, 233) on a backing (12, 28, 106, 218) in side-by-side relationship. The wrapping film material conforms to the outside surface of the row (19, 27, 100, 102, 214) of pile so as to define a bulb or bulbs which are completely filled with pile. Single row (19, 27) pile weatherstripping is made by wrapping the pile (10, 24) with the film material (14, 25) after first ultrasonically welding the film material along one edge thereof to the backing (12, 28) under the pile. Then, the film material (14, 25) may be bent around the pile as it moves through a guide (88). The film material (14, 25) is then attached along the opposite edge to the backing thereof so as to completely enclose and clad the row (19, 27) of weatherstripping.

Abstract: Weatherseals are provided by a pair of base members which may be attached to a pile formed by winding fibers around a band as the band travels along an endless path. A section of the pile on one side of the endless band is cut to provide cut pile section and a continuous pile section. The continuous pile section forms the bow, arch or loop by disposing the base members in side-by-side, back-to-back, or perpendicular relationship. The cut pile section may be removed at the base members or halves of the cut pile section maybe left in place. The cut pile section halves and the outside surface of the bow, arch, or ioop may be attached by base members to a member, such as by adhesive or via one or more T-shaped slots, that is in sealing relationship with another member and engagable therewith to provide a resilient seal.

Abstract: Filamentary materials, such as yarn (18), is wound a frame (28), provided by pairs of movable filaments or wires (35, 38), about which the end of the spindle (22) rotates provides the turns (26) of the winding as the article having the winding is moved along a process path. Mechanically or hydraulically actuated pins (34) support the winding frame in a fixed position. The filaments of the frame may be provided by laterally spaced pairs (44, 46) of filaments of weldable material.

Abstract: Articles (12) made by winding of filamentary material (11), such as yarn and thread, are especially suitable for providing brushes and pile weatherstripping. In order to enable the yarn (11) to be unwound and payed out of spools (24) disposed in a stationary or static array, the yarn is fed from the spools (24) through a rotating spindle (30). A frame (14) located at the beginning of the path and may be provided by laterally spaced pairs of wire (52) which travel around posts (36) provided by rollers on a stationary bracket (38). In order to support the bracket (38) and the frame (14), a shaft (28) reciprocates a pair of support rods (100, 102) in synchronism with the rotation of the spindle (30). Bindings (60, 62) are applied to the ends of the loops (54) as they leave the winding station (14). Slitters (20) divide the loops (54).

Abstract: Block seals of pile weatherstripping (6), which may be inserted in doorjambs or window sash and are sometimes called dust plugs (15), are provided by hinged segments (16-21) of a continuous length of pile weatherstripping folded against each other. The pile may have an infiltration barrier providing a fin (4) which extends along a continuous serpentine path having loops (8) bridging the hinges (3). The hinged sections are connected by an adhesive-backed sheet (5). The block seals are adapted to be manufactured by a continuous process where the backing or base strip (7) of a continuous length of pile weatherstripping (1) is slit or notched from opposite spaced edges, leaving sufficient material in the backing to provide the hinges (3). The continuous serpentine barrier fin (4) allows the dust plug (15) to be installed oriented either with the ends or sides of the pile facing the moving member of the door or window to be sealed, while maintaining the fin infiltration barrier.

Abstract: A pile article is provided having a band of textile material, and a plurality of fiber loops defining a pile having sides from ends extending longitudinally along the band. The band is ultrasonically welded to the ends and a portion of the sides of the pile, and is sufficiently wide to support the sides of the pile substantially upright. An interior textile strip may optionally extend longitudinally within the pile at the ends of the pile and within a portion of the pile sides.

Abstract: Dust plugs provide seals for openings in door frames and window frames to seal against air or water infiltration. The dust plugs are made continuously and automatically by feeding several weatherstrips having piles extending from rigid backing through a tool having side by side slots there through which extend from an anvil surface thereof. The backing strips rest on the surface in edge-to-edge relationship. An adhesive tape having a contact adhesive on one side thereof is fed synchronously with the pile weatherstripping in juxtaposition with the weatherstrips and in contact with the exposed sides of the backing strips. The dust plug material consists of the tape in contact with the weatherstrips and provides an assembly of the weatherstrips and the tape. Counter rotating puller belts engage dust plug material which may then be wound on a reel. For installation of the dust plug, the dust plug material is unwound from the reel and cut into dust plugs of desired length.

Abstract: A cushioning member is located between each support frame and the corresponding side of the shutter. The cushioning member includes a pair of belt-shaped base members and pile yarns bridging between the base members. Some of the pile yarns are cut at intermediate portion between the base members, which forms opposing first and second cut pile yarns with a cut in between. One of the base members is attached to each support frame, and the other base member contacts the shutter. The cut permits the cushioning member to flexibly respond to movements of the shutter and satisfactorily exerts a cushioning function to suppress swaying of the shutter.

Abstract: In order to make weather seals from closed cell elastomer foam material, molten plastic is extruded over a substrate of the foam material. Surface reactions during extrusion are avoided by continuously pulling the substrate through an oven chamber to degas (and remove moisture from) the material at least on its outside to a limiting thickness of the order of 10-30 mil to form a skin or crust. The extrusion of the over-coating is carried out to form a sleeve while the substrate is still hot. Since the skin is a degassed region on the outside of the foam substrate, reactions which may cause blistering and prevent the extrusion of a smooth and firmly adhering skin are avoided. The substrate material is preferably a thermosetting EPDM rubber closed cell foam, and the over coating material is a thermoplastic elastomer (TPE).

Abstract: Pile weatherstripping is provided by a flat pile of strands which are tensioned to spring outwardly to straight condition to provide a pile weatherstrip, when bent and inserted into a T-slot or other kerf in a member such as a window or door frame or sash. The tendency of the bent parts of the pile to spring away from each other facilitates retention of the pile after insertion into the slot. A locking fin, more rigid than the pile, is preferably used. This locking fin engages steps or edges in the throat of the slot thereby impeding withdrawal of the weatherstripping from the slot. One or more barrier fins may also be assembled with the strands constituting the flat pile. The pile can be operated in bending mode or in columnar compression (crushing mode). Bending mode operation can be over a bending range so as to accommodate a large range of clearance between a sash and a frame or other members which are sealed by the pile weatherstripping.

Abstract: In order to facilitate the installation of weatherstripping into channels, usually T-slots, of frames in windows and doors, variations in size of the slots is accommodated by changing the size of interference members extending from the backing strip of the weatherstripping. A forming tool, such as a shaft having a forming surface or on which a forming roller is movably mounted in a support structure. The support structure is disposed adjacent the mechanism of the insertion apparatus which feeds the weatherstrip into the T-slot of the frame. The support has a channel via which the weatherstrip passes into the insertion mechanism and thence into the T-slot in the frame. A wall in the support member presents the forming tool to the interference portions of the backing strip of the weatherstripping and is operative to swage and crimp or otherwise change the cross sectional size of the backing strip in relationship to the size of the T-slot which receives the backing strip.

Abstract: Static brushes suitable for handling electric charges so as to obtain static electricity control including static discharge in web handling devices such as printers, presses, xerographic copiers and other film and paper handling equipment is made of conductive thread wound in continuous turns around a mandrel and slit to form open-ended loops forming the brush bristles. A continuous element or elements, such as a wire or wires, may be placed on the mandrel and the turns are wound thereon. Strips of pressure-sensitive tape are adhered along the sides of said loops and encompass the element(s) so as to hold the loops and elements assembled as unitary brushes, which may readily be installed in equipment requiring static control by removing releasable paper over pressure-sensitive material on the outside of these strips. Double-sided pressure-sensitive adhesive tape may be used in constructing the brushes.

Abstract: A glass channel insert to guide, support, and seal a slidable window in a supporting channel window frame. The channel insert includes a centrally disposed durable plastic strip to bear the weight of the window and side sealing or glide members, preferably a laterally disposed pair of opposed pile weatherstrips to seal the inner and outer window surfaces from wind and water. The bearing strip and the weatherstrips are adhered to a common surface of a flexible backing web, preferably by simultaneous ultrasonic welding, providing a substantially planar glass channel element which can be wound as a roll. In installation, the planar element is folded longitudinally to form a U-shaped glass channel insert, which can be sliced transversely at intervals along its back side to permit bending of the insert to follow the curved edges of windows.

Abstract: Pile weatherstripping having rows of pile and longitudinal fins both within and external to the rows of pile. The heights of the fins with respect to the height of the pile may be independently varied and controlled. A travelling endless band receives a pair of first webs providing internal fins on opposite sides of the band. The first webs are indexed to the edges of the band, which defines the heights of the fins. Each web may be independently indexed. Alignment of the webs on the band is provided either by an aligning fixture or by coining the webs to provide lines of indentations which index the webs at the edges of the band. The yarn which forms the pile is wound around the first webs. Second webs providing the external fins are indexed through the yarn and first webs to the edges of the band and are also aligned by a second aligning fixture or by coining. Backing strips are attached, as by ultrasonic welding, along the edges of the band. Then the yarn is slit without cutting into the webs.

Abstract: A weatherstrip assembly has a backing strip 30 with one or more local interference members in the form such as of nubbins 40A or alternative nubbins, which frictionally engage a channel or T-slot holding the backing member 30 and thereby restrict movement of the backing member 30 within the channel or T-slot, and especially movement of the weatherstrip along (longitudinally of) the length of the channel. Lateral (side to side) movement of weatherstrip is also restricted.

Abstract: Pile weatherstripping having rows of pile sandwiching a fin is fabricated so as to precisely locate the height of the fin with respect to the height of the pile. A travelling endless band receives webs providing the fins on opposite sides thereof with the edge of each web, which defines the height of the fin, precisely positioned on a side of the band and the other edge overhanging the edges of the band. Alignment of the webs on the band is provided either by an aligning fixture or by coining the webs to provide lines of indentations which index the webs at the edges of the band. The yarn which forms the pile is wound around the webs and the band and serves to wrap the overhanging portions of the webs around the band, or a guide may be used to facilitate wrapping of the webs around the band, prior to winding of the yarn. Backing strips are attached, as by ultrasonic welding, along the edges of the band. Then the yarn is slit without cutting into the webs.

Abstract: A weatherstrip assembly 8 for a window 6 includes a weatherstrip 20 with a backing strip 20 with pile fibers 22. The weatherstrip 20 is retained in a channel 10 of window 6. The channel 10 has a flexible wall 14 that is resilient and temporarily deformable to expand the cross-sectional area of channel 10 while the weatherstrip 20 is inserted into channel 10.
