Abstract
In an apparatus for texturing an outer surface of an extruded thermoplastic resin article, thermoplastic resin article is formed from a molten thermoplastic resin and a liquid jet printer head is adapted to impinge a stream of liquid against said thermoplastic resin for rapidly cooling said thermoplastic resin in impinged area to imparting texturing to said extruded thermoplastic resin article.
Claims8
An apparatus for marking an outer surface of a thermoplastic resin article comprising (a) means for extruding a molten thermoplastic resin article (b) a non contact liquid jet printer head, having associated therewith electronically charged deflector plates which said printer head produces a multitude of droplets of liquid, for impinging a stream of said liquid droplets against said outer surface of the molten thermoplastic resin article thereby resulting in localized cooling and solidification to impart a raised mark on said molten thermoplastic resin surface in an impinged area and (c) means for subsequent cooling of the thermoplastic resin article.
