Abstract

639,099. Drying webs. ALEXANDER, P. April 1, 1948, No. 9271. [Class 34(i)] Moisture is removed from the surface of moisture absorbent sheet material on which metal is to be deposited (by thermal evaporation in a vacuum) by heating one surface of the material in a vacuum chamber by radiant heat. A roll of the absorbent material is unrolled and progressively exposed in a vacuum chamber (pressure 0.05 to 0.5 mm. of mercury) to radiant heat and passed out of the heating chamber whilst hot to a communicating rerolling chamber in which the pressure is maintained at a higher pressure than that in the heating chamber so that one surface only of the web is freed of its moisture and plasticizer the vapour being prevented from gaining access to the re-rolling chamber. In the apparatus shown, a vacuum, heating chamber 1 is enclosed within a chamber 2, the chamber 1 having as a source of radiant heat an electric heater 3. The web 4 emanating from a supply roll 5 in the re-rolling chamber passes over guide roller 6, through slit 7 and into heating chamber 1 where it passes before the heater 3 and returns via collers 8 and 9 to the take-up roll 10 which is driven by a clockwork motor 11. In a modification the supply roll 5 is'in the heating chamber 1. In a second modification the two chambers are formed by dividing a single chamber by a partition. Specification 551,757, [Group II], is referred to.
