ABSTRACT:
A process for making a pile-surfaced product comprises feeding a thermoplastic film and a backing between rollers, the roller which engages the thermoplastic being heated so as to cause the thermoplastic to adhere thereto, and subsequently separating the backing and the thermoplastic from the heated roller so that the thermoplastic is drawn into filaments. The nature of the pile is controlled by hauling off the backing and the thermoplastic over a rod or bar which fixes the point at which the thermoplastic separates from the heated roll, controls the path of the product as it moves away from the heated roll and guides a cooling fluid onto the back of the backing.
