Abstract

1483592 Sheet forming PLASTONA (JOHN WADDINGTON) Ltd 14 Aug 1974 [21 Aug 1973] 39456/73 Heading B5A Prior to thermoforming a web of plastics, e.g. polyolefin, it is heated by immersion in a bath 14 of a heating liquid, e.g. molten metal, glycerine, polyethylene glycol, polypropylene glycol, or ammonium nitrate, the liquid being removed from the web as it leaves the bath, e.g. by gas, vapour, flame jets, nip rollers, or an additional bath of different liquid. The web is fed from a drum 34 over a removable guide system 12 having rollers 18, 20, 22, and then via an outlet duct to the thermoformer, not shown. The duct 40 is heated by pipes 52, 54 through which liquid from the bath is circulated. The bath is heated by heaters 24, 26 which are thermostatically controlled. The web additionally can be heated by other means before or after passing through the tank.
