Abstract

1308576 Embossing D MURPHY 19 April 1971 [7 April 1970] 26422/71 Heading B6J A thermoplastics web 20 is softened by passage around heated roller 2, embossed on both sides by passage around patterned rollers 3 and 4, and cooled to set the embossments in coating chamber 9. The embossing pressure may be adjusted by movement of roller 4 on pivoted lever 5 under the control of screw jack 8. Cooling is by means of air blast from a fan 18. Alternatively the web may be heated by passage through a heating throat and cooled by passage around a cooled drum. The thermoplastics web may be polyethylene, polypropylene or polyvinyl chloride.
