ABSTRACT:
Apparatus for manufacturing sheet-like material having a thermoplastic pile surface includes a cylindrical roll having a heated surface, a feed arrangement for feeding a foundation layer and a thermoplastic material to the heated surface of the roll with the thermoplastic material located between and in contact with the surface and the foundation layer and a withdrawing arrangement for withdrawing the foundation layer and thermoplastic material from the heated surface in a manner such that the thermoplastic material is drawn into filaments which are attached to the foundation layer. In one embodiment the laminate is withdrawn from the roll over a tube or bar and a jet is provided for directing a jet of cooling fluid from the back of the foundation layer into the area where the filaments are formed. In another embodiment the laminate is withdrawn from the roll over a rod or bar which is inter-related with a front jet so that cooling fluid is deflected into the space between the bar and the roll.
