Molded parts with discontinuous fabric surface areas and processes for their production
First Claim
1. A process for preparing a molded plastic article comprising a substrate plastic component with discontinuities or voids and a fabric surface area with discontinuities or voids corresponding and aligned to those in the substrate plastic component comprising the steps of:
- (a) laminating to the back side of a fabric a support layer, (b) cutting or shaping the laminated fabric to generally conform to the shape and size of a desired fabric surface area and incorporating discontinuities or voids to correspond to those in the plastic substrate component, (c) inserting the shaped laminated fabric piece from step (b) into a molding cavity with the discontinuities and/or voids properly aligned with the mold surface and holding the piece in place, and (d) molding the plastic substrate component in the molding cavity, and (e) removing the molded plastic article from the mold.

Abstract
The present invention thus provides a fabric-laminated plastic part and a novel process where the fabric that provides the surface is pre-laminated with a support layer and supplied into a molding process where a plastic substrate component is molded. The fabric surface piece is precisely located and securely bonded by selection of a support layer plastic material having sufficient heat resistance and/or thickness to sufficiently resist melt softening and stretching during the molding process. This process and fabric laminated plastic article are especially suited for preparing thin-wall, articles that need to have precisely located, smooth fabric surface areas corresponding to discontinuities, voids or openings in the underlying molded plastic article.
