摘要： A carpet product (10) includes a pile fabric layer (20), a stabilizing layer (30) adhered to the back of the pile fabric layer (20) to provide dimensional stability against concentrated stresses exerted against the upper surface of the carpet and a balancing layer (40) disposed below the stabilizing layer (30) which has thermal response and moisture absorption characteristics selected for compatibility with the pile fabric layer (20). When the carpet product (10) is exposed to temperature extremes or changes in ambient humidity, stresses exerted by the expansion or contraction of the pile fabric layer (20) create a bending moment around the stabilizing layer (30). However, the balancing layer (40) creates comparable stresses on the lower side of the stabilizing layer (30) and exerts an equal-but-opposite bending moment which balances the moment exerted by the pile fabric layer (20). The resulting carpet product exhibits enhanced flatness and floor hugging characteristics when subjected to temperature extremes or changes in the ambient humidity.

摘要： "CARPET PRODUCT WITH INTEGRAL BALANCING LAYER" An improved carpet product includes a pile fabric layer and a stabilizing layer adhered to the back of the pile fabric layer to provide dimensional stability against concentrated stresses exerted against the upper surface of the carpet. A balancing layer disposed below the stabilizing layer has thermal response and moisture absorption characteristics selected for compatibility with the pile fabric layer. When the carpet product is exposed to temperature extremes or changes in ambient humidity, stresses exerted by the expansion or contraction of the pile fabric layer create a bending moment around the stabilizing layer. However, the balancing layer creates comparable stresses on the lower side of the stabilizing layer and exerts an equal-but-opposite bending moment which balances the moment exerted by the pile fabric layer. The resulting carpet product exhibits enhanced flatness and floor hugging characteristics when subjected to temperature extremes or changes in the ambient humidity.

摘要： A method and apparatus for coating the back of carpet products providing improved control over coating weight, uniformity, and penetration. A layer of adhesive is formed on a rotating coating roll, and the upper edge of an applicator blade is brought into contact with the coated roll. The layer of adhesive is transferred to the upper edge of the applicator blade and flows under the effect of gravity to the lower edge of the blade. The back of the carpet is then pressed against the lower edge of the blade, simultaneously applying and spreading the adhesive.

摘要： A method of forming a layer of blown cellular urethane on a primary carpet backing comprising the steps of preparing a mixture of reactive urethane forming agents, controlling the temperature of the reactive mixture, shaping the reactive mixture into a layer upon a latex film, heating the urethane forming mixture to initiate chemical blowing of the mixture, applying the underside of a previously tufted and heated primary carpet backing directly to the upper surface of the mixture, heating the mixture to a predetermined temperature, applying pressure to the carpet and mixture and stripping the carpet and cellular urethane layer from the conveyor belt.
