A method of molding a plastic-backed carpet blank to a desired shape uses a minimum of work force and carpet material. The method utilizes a portable frame assembly having an open rack with yieldable holding clamps. The holding clamps are used to suspend a plastic-backed carpet blank in the rack. The frame assembly has a set of wheeled legs which allows it to be readily transported between work stations such as a heating zone and a molding zone. The yieldable holding clamps maintain the carpet under constant tension during the molding zone to result in a high quality molded carpet.
