    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.

    Abstract: The foam slush molding apparatus of this invention comprises a mold and a hot air jacket, and an optional heat retaining hood. The hot air jacket and the optional heat retaining hood are provided along and a certain distance apart from the molding surface on which a resin is heated and fused. The molding surface and the jacket form a first hot air chamber for heating, and the jacket and the optional heat retaining hood form an optional second hot air chamber for heat retention. The apparatus permits uniform heating and foaming at an efficient molding cycle.

    Abstract: A method and apparatus are provided to prevent specks of condensation products being formed on a plastics material film produced by a calendering technique. In the method, after the film has left the final calender roller, the film is passed around at least one take-up roller and is blown against the shell of the roller by compressed air issuing from nozzles. While on the shell of the roller the film is cooled to a temperature below the condensation temperature of the volatile substances released from the surface of the film.

    Abstract: A process is provided for covering an interior part with a layer of leather. The process includes subjecting a layer of leather to a heat treatment. A water-soluble protective film is then applied to the decorative upper side of the leather. The area of the interior part that is to be covered is cleaned using a solvent. An adhesive agent is applied to the cleaned area of the interior part using a brush. An adhesive agent is sprayed onto the backside of the leather layer. The two adhesive agents on the interior part and on the leather layer are ventilated. The leather layer is then applied to the interior part, and the water-soluble protective film on the decorative upper side of the leather is removed. The adhesive agent is then hardened.

    Abstract: In production of solid films (e.g. a floor covering wear layer) by casting, fusing and then cooling a vinyl chloride polymer plastisol, good physical properties of the plastisol and films are provided by use of surprisingly small amounts of plasticizing ester including diester selected from alkyl benzyl succinates, glutarates and mixtures thereof. Using such small amounts of ester, the films have unusually high stain resistance.
