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

Apparatus and methods for making pile articles and improved pile articles made therewith

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.

Textile backed pile article and method for making same

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.

Apparatus and method for making pile articles and improved pile articles made therewith

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

Apparatus and method for making articles having filamentary material

Block seals of pile weatherstripping (), which may be inserted in doorjambs or window sash and are sometimes called dust plugs (), are provided by hinged segments (-) of a continuous length of pile weatherstripping folded against each other. The pile may have an infiltration barrier providing a fin () which extends along a continuous serpentine path having loops () bridging the hinges (). The hinged sections are connected by an adhesive-backed sheet (). The block seals are adapted to be manufactured by a continuous process where the backing or base strip () of a continuous length of pile weatherstripping () is slit or notched from opposite spaced edges, leaving sufficient material in the backing to provide the hinges (). The continuous serpentine barrier fin () allows the dust plug () 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.

Pile weatherstripping dust plugs

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. Guides on upstream and downstream ends of the tool bring the tape into contacting relationship with the weatherstrips to provide the assembled dust plug material.
