Abstract

968,291. Making thermoplastic sheet material. JAMES HALSTEAD Ltd. June 14, 1963 [June 7, 1962], No. 21998/62. Heading B5A. Thermoplastic material 6, e.g. P.V.C., is formed into a continuous sheet by passing it through the nip of a heated calender so as to cling to an endless band 3 passing around one of the nip rolls, the sheet being cooled whilst on the band and separated therefrom. Cooling means 5 such as air or water sprays are provided and the separated sheet is taken away by a conveyer 9. The band 3 is of metal or silicone treated glass fabric and may be provided with a pattern which becomes impressed on the sheet. It is reheated at 8 before entering the heated calender rolls.
