Benefits of technology

[0008]According to another potentially preferred feature, the textile face structure is preferably substantially relaxed such as by steaming or the like prior to application of the polyurethane so as to substantially avoid subsequent deformation due to shrinkage.

Problems solved by technology

One disadvantage of prior flooring or floor covering constructions has been the relatively complex arrangement of various structural layers to provide dimensional stability and wear performance of the products.

Embodiment Construction

[0039]Referring to FIG. 1 of the drawings, an exemplary formation system 10 is illustrated for use in the production of surface coverings or polyurethane backed products such as carpeting, carpet tile, area rugs, roll goods, and / or floor mats. According to the illustrated and potentially preferred embodiment, the formation system 10 includes an endless belt 12 formed from a material such as PTFE woven fiberglass or the like. As shown according to the illustrated process, a mass of uncured polyurethane composition 14 is preferably deposited directly onto the belt 12 and then adjusted to a desired height by a leveller 16 such as a doctor blade, air knife, or the like. The thickness of the levelled polyurethane composition is preferably in the range of about 0.10 inches to about 1.0 inches, more preferably about 0.16 inches to about 0.60 inches although higher or lower thickness levels may likewise be used. While direct application of the polyurethane composition onto the belt 12 may b...

Abstract

A surface covering such as a carpet, carpet tile, area rug, floor mat or the like incorporating a textile face disposed in contacting overlying relation to at least a polyurethane layer. One or more optional intermediate structure layers may be disposed within the polyurethane and one or more optional backing layers may be disposed across the underside of the polyurethane.

Description

TECHNICAL FIELD [0001]In accordance with at least one embodiment, the present invention relates to surface coverings such as floor coverings having a show surface material in contacting overlying relation to a backing of polyurethane with or without additional structures, layers, backings, and / or the like. In particular, but not exclusively, at least one embodiment of the invention relates to a surface covering such as a carpet, carpet tile, area rug, floor mat or the like incorporating a textile face, such as a tufted, bonded, flocked, needled, needle punched, woven, non-woven, or knit fabric structure disposed in contacting overlying relation to at least a polyurethane layer. The polyurethane layer may form a precoat, tiecoat and / or backing and may be foam or non-foam, and may preferably be flexible. One or more optional intermediate structure layers may be disposed within the polyurethane and one or more optional backing layers may be disposed across the underside of the polyuret...
