APPARATUS AND PROCESS FOR THE PRODUCTION OF PILE SURFACE ARTICLES

摘要

S OF THE DISCLOSURE A process for the production of pile-surfaced material which comprises the steps of interposing a thermoplastic material between a backing and a substantially smooth heated surface, holding the backing against the thermoplastic material so that the bonding of the backing to the thermoplastic material and adhesion of the thermoplastic material th the heated surface occurs, parting the thermoplastic material from the heated surface over a bar so that fibrils are drawn out from the thermoplastic material between the heated surface and the backing, hardening the fibrils as they are drawn out by a stream of cooling fluid and separating the fibrils from the heated surface in which said hardening is achieved at least in part by directing the cooling fluid against the heated surface at a position just beyond the point where the pile separates from the heated surface so that the fluid is deflected into the space between the heated surface and the product. The present process seeks to improve both the uniformity of pile produced by this type of process, to allow uniform piles to be produced at higher speeds than before possible and to provide a versatile process which is readily adaptable to produce varying types of pile.
