METHOD OF MAKING A TRIM STRIP ABSTRACT OF THE DISCLOSURE The disclosure relates to a method of making a trim strip comprising the extrusion of a vinyl material to form a body which is so shaped that it can be confined in a peripheral slot in a roll, thereby to permit substantial pressure to be applied on the extruded body and a decorative strip by a mating roll. The top portion of the extruded body has side extensions which are supported by the edges of the recessed roll; thus, substantial pressure can be applied on the entire top of the decorative surface strip and the body to produce an adhesive bond or a bond by heat sealing. After the body is cooled, it is advanced through a number of aligned milling cutters to machine aligned recesses in the sides of the body to produce a retention cutout. After being machined to depth, the trim strip is advanced through a pair of grinding wheels to accurately form and space the recesses. During the extruding operation, a coated wire may be embedded within the body in the conventional manner.
