Angled fiber pile brushes are anchored to a backing at a predetermined angle to the perpendicular are made by winding yarn around a flat band The pile is anchored to a backing which is disposed at the desired angle to the band The band wrapped with the pile and the backing move together along an assembly path Ultrasonic horns each have a split end, which moves perpendicular to the backing Mechanisms guide the backings and the band each include a slotted plate o&#x3c0;ented at the requisite angle The edge of the pile wrapped band extends through the slot in the guide into contact with the backing The band and the horn move in the same, horizontal plane, thereby simplifying the construction of the assembly apparatus The wrapped yam may be slit longitudinally by a slitter in the direction o the travel to provide a pair of angled brushes.

Angled fibrous brushes of fibers fixed to a backing and method of manufacturing same

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

Pile weatherstripping, which is clad with a wrapping of a film () of flexible material, has one or more rows () of pile () on a backing () in side-by-side relationship. The wrapping film material conforms to the outside surface of the row () of pile so as to define a bulb or bulbs which are completely filled with pile. Single row () pile weatherstripping is made by wrapping the pile () with the film material () after first ultrasonically welding the film material along one edge thereof to the backing () under the pile. Then, the film material () may be bent around the pile as it moves through a guide (). The film material () is then attached along the opposite edge to the backing thereof so as to completely enclose and clad the row () of weatherstripping. The film material may be wrapped around one row () of two adjacent rows () of pile () and attached to the backing (), leaving the other row () unclad. The film material () may be wrapped separately around adjacent rows and attached to the backing () to provide two clad rows () of weatherstripping. By selection of the porosity of the film material () and the density of the pile (), weatherstripping having desired compressibility and air and water infiltration control properties may be produced.
