Weatherstrips () having opposed pile sealing elements () are installed in opposed slots in a frame member () so that the piles may engage opposite sides of a panel, shutter or screen (), by insertion apparatus having laterally-movable slotted guides (). The weatherstrips are driven through the slots in the guides by a drive wheel (). A laterally reciprocating cutter () has openings (), through which the weatherstrips are driven, and shearing edges () for cutting ends of the weatherstrips to facilitate entry of the weatherstrips from the slots in the guide into the slots in the frame member. Metering wheel () engages at least one of the weatherstrips moving through the guides, and provides for actuation of the cutter, when the desired length of the weatherstrips is driven through the guides; the length corresponding to the length of the frame member which receives the weatherstrips.

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.
