Abstract: An edging member for a window glass of an automobile door is provided with a plurality of contacting surfaces against which window glass is contacted. Each contacting surface is provided with a rough contacting layer respectively including a synthetic resin prepared by mixing large and small particles or grains of materials having different melting points, such as nylon, urethane, fluoro-resin and polyolefin resin, polystyrene resin and the like. The rough contacting layer is extruded simultaneously with the extrusion molding of the edging member.

Abstract: An edging member of a window glass for an automobile door is provided with a plurality of contacting portions to which the window glass is contacted. Each of the contacting portions is provided with a batten surface layer including a synthetic resin such as nylon, urethane and polyolefin resin, and powders or grains of mica, molybdenum and/or graphite mixed with the synthetic resin. A rough surface having projections and recesses is formed on the front surface of the batten surface layer by extruding the batten surface simultaneously with the extrusion molding of the edging member.

Abstract: A weather strip allowing the opening and closing operations of the window glass in a door of automobile to be performed is formed by a base portion made of a hard synthetic resin, a support portion made of a soft synthetic resin and a contacting band layer comprising two synthetic resins of different melting points, of which powder or particles of the synthetic resin of a high melting point are mixed with the synthetic resin of a low melting point. The contacting band layers are provided on the portions of the base portion and support portion where the window glass abuts. The contacting band layer is formed by extrusion simultaneously with the extrusion of the base portion and support portion, whereby a rough face is integrally formed on the surface of the contacting band layer.
