    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.
