Patent ID: 8083875

Claim:
A method for making carpet having an underside comprising: a. laying a web onto an advancing belt in a carpet manufacturing line; b. applying a resin layer onto the web, wherein the resin layer comprises a viscosity; c. laying in tufted facecloth on the resin layer to form a composite structure, d. heating the composite structure at least to a temperature at which the viscosity of the resin layer begins to decrease; and e. while maintaining the temperature of the composite structure at or above the temperature at which the viscosity of the resin layer begins to decrease, applying pressure to the composite structure by passing the composite structure between a first pressure roller and a second pressure roller, wherein the first pressure roller contacts the tufted facecloth and the second pressure roller contacts the web and the pressure at least partially drives the web into the resin layer such that the resin layer is exposed on the underside of the composite structure, wherein at least one of the first pressure roller and second pressure roller is chilled.
