A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing using a roller application system. The greige is conditioned prior to coating and the polyurethane coated greige is contacted with the secondary backing and the laminate is tensioned and supported to maintain the laminate structure substantially through the polyurethane curing process.
