Abstract
Abstract A synthetic resin molding for the use of automotive vehicles are of the type in that an elongated molding product is cut into a predetermined length and mounted to a body, a window frame, a bumper or the like of automotive vehicles. The molding is constituted as such that a plurality of core yarns of glass fiber are applied to the interior of a body of the molding in parallel relation along the longitudinal direction by continuously feeding a plurality of yarns of glass fiber into a mold in the body of the molding. Therefore, the thermal contraction can be greatly minimized.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
78 words
A generally elongated synthetic resin molding having a predetermiend length that is mounted on the body, window frame or bumper of an automotive vehicle, said synthetic resin molding comprising: (a) a body of molding formed by extruding a synthetic resin, and (b) a plurality of core yarns of glass fiber embedded within said molding, wherein said glass fiber yarns embedded within said molding are disposed in parallel relation to each other along the longitudinal direction of said molding.
Claim 2
Dependent Claim
78 words
A generally elongated synthetic resin molding having a predetermiend length that is mounted on the body, window frame or bumper of an automotive vehicle, said synthetic resin molding comprising: (a) a body of molding formed by extruding a synthetic resin, and (b) a plurality of core yarns of glass fiber embedded within said molding, wherein said glass fiber yarns embedded within said molding are disposed in parallel relation to each other along the longitudinal direction of said molding.
