Abstract

Linear weatherstrips and dust plugs (20, 30, 51, 75) having a plurality of such weatherstrips (10-12, 31-35, 40-42, 60-62) in side-by-side relationship are provided with multidirectional flexibility so as to be useful in corners of window frames and doorways by the use of backing strips (16-18) which are made of lineal strings (19) of thermoplastic material which are criss-crossed to provide intersections and bonded at the intersection to provide an embossed surface. The piles (13-15) are attached to one side of the backing strips (16-18) leaving areas between the piles and the edges of the backing strips (16-18) in assemblies of the weatherstrips on a carrier (22) with the backing strips in edgewise-adjacent relationship. This relationship may be provided by the edges of the backing strips being in contact with each other. Alternatively, the areas of the backing strips of adjacent weatherstrips, between the edges and the piles, may be in overlapping relationship. The carrier (22) is bonded ultrasonically to the backing strips in their adjacent or overlapping areas. When the backing strips are overlapping, the carrier (22) may be eliminated.
