  • Patent number: 5154870
    Abstract: An apparatus and process for making extruded colored thermoplastic resin sheets is shown and described. In this process, a colored thermoplastic sheet material is encapsulated within a clear material. The colored material as it merges with the clear material is subjected to a clear material flow direction vector which causes the colored material to spread or become wider than the color material orifice. The spreading due to clear material flows in a widthwise direction produces a uniform taper to the colored edge, and the point at which the colored material stops and the finished product is barely perceptible. In this apparatus, a clear flow thermoplastic extrusion die has placed within its manifold a colored material distributing inner pipe which has an orifice for inserting color material into the flow of the clear material. The color insertion occurs at a point where the clear material has a flow vector in the widthwise direction and towards the clear portion of the finished product.
