Abstract
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 oπented 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.
