ABSTRACT:
Weatherstrip is composed of a substrate having a pile strip upstanding from one surface thereof. In one embodiment the substrate is made of two different materials, one of which is a thermoplastic material that is heat sealed by being passed over a heated bar to prevent the edges of the weatherstrip from fraying. The other material maintains the structural integrity of the substrate during heat-sealing. Essentially the whole of the undersurface of the substrate including the portion immediately beneath the pile strip contains the aforementioned thermoplastic material, making it possible for the substrate to be surface mounted on a component such as a door or window fabricated of a material compatible to the thermoplastic material. In another embodiment the substrate may be composed entirely or partly of the thermoplastic material, and the same thermoplastic material is extruded onto the back of the substrate.
