ABSTRACT:
An apparatus for forming a multi-colored integral vinyl skin shell including a heated mold and dual powder box arrangement wherein the mold is formed to include alternately positioned tear surfaces and recessed surfaces. The powder box has a plurality of spaced dams or dividers formed therein such that the dams cooperate with the respective recessed surfaces of the mold to provide clearance therewith that permit different colored powders in the compartments between the dams to cover the previously cleared tear surfaces and to flow past the selectively formed free ends of the dams to become integrally secured to the adjacent edge portions of the shell segments remaining in the areas of the recessed surfaces of the mold, forming the multi-colored, integral plastic shell. The dams or dividers have tapered sides formed on their distal ends for approximately the outer two thirds of the width of each dam, and an opening is formed therebetween into a central hollow section for recovering "contaminated" or mixed powders from two adjacent compartments.
