Abstract: The present invention relates to a method and apparatus for forming a layer of blown cellular polyurethane foam on a textile material, such as a carpet backing. The method includes applying to a textile material a layer of reactive polyurethane forming agents, heating the layer so as to cause chemical blowing of the mixture and applying to the layer during the chemical blowing thereof a thermal insulating blanket for a time sufficient to control the blowing of the mixture to a desired degree. Apparatus for performing the process is also disclosed.

Abstract: A method is disclosed for flatproofing a tire and wheel assembly with a flexible, lightweight foam-fill by supplying at least two polyurethane reactive materials to a static mixer. The static mixer mixes the reactants, and a nucleating gas is supplied to the mixed reactants in the static mixer to form a liquid reactant mixture with entrained gas. The reactant mixture is injected into the tire and wheel assembly where the mixture reacts and foams replacing the air in the tire with a flexible, lightweight semi-open cell foam-fill. The resulting foam-filled tire and wheel assembly is then allowed to cure.

Abstract: This invention is a floor covering which may be easily removed from its underlying surface and which resists buckling or folding when rolled, comprising: (a) a facing layer; (b) a release backing layer made of post-consumer recycled nonwoven polyester fabric of relatively short fibers, continuous filament fibers, or a mixture thereof and (c) an intermediate polymer layer which is bonded to the release backing layer on one side and directly or indirectly to the facing layer on the other side. A process for preparing a polyurethane foam cushioned floor covering is also disclosed.
