Abstract

1526918 Forming films FUJI PHOTO FILM CO Ltd 24 June 1977 [6 July 1976] 26686/77 Heading B5B Thermoplastic polymer sheet esp. of polyethylene terephthalate is formed by extrusion on to a moving cooling body and the sheet is caused to adhere to the body by the supply of a liquid in vapour or fine droplet form to the surface of the polymer sheet which faces the cooling body and is to contact it at a position between the extrusion die and the surface of the cooling body. The liquid used has a boiling point of 60-200‹ C. a viscosity below 5 centipoise and a surface tension below 100 dynes/cm. Water is preferred.
