Abstract

542,080. Casting films. DREYFUS, H. May 22, 1940, Nos. 9058/40 and 4609/41. [Class 2 (ii)] A liquid filmforming composition is fed continuously on to a series of film-casting plates 7 moved relatively to the feeding hopper 17 ; - the layer of composition cast on each plate is allowed to. set before the casting of another layer, and the plates are finally removed from the apparatus for the purpose of stripping the layers from them. The plates 7 may be of glass, and are carried by trucks 6 on an endless track 4 which passes through a drying tunnel 1 consisting of two straight lengths 2 joined by semi-circular lengths 3. The trucks 6 are connected by loop couplings 8 and are driven by an endless chain 10 in a pit 11 below the track 4. One or more chains may be used, and lugs 12 on the chains engage lugs 13 on the trucks. The hopper 17 is placed near the point 16 above the trucks and the plates 7 can receive as many layers of composition as required. When the desired film thickness is reached, trucks are withdrawn from the tunnel 1 to a loop 21 by means of points 22 and a door 23. At the point 25 on this loop the plates 7 are lifted from the trucks and transferred to a soaking station 27 and a stripping station 28. From this the films are passed to a seasoning chamber 29 and the empty plates are returned to the trucks, ready for re-use. In a modification, the glass plates are carried by auxiliary trucks supported on main trucks, from which they can be removed laterally for further treatment when the depositions reach the desired thickness. In a further modification, tracks are arranged in radial tunnels opening from-a central turntable, so that trucks carrying the plates can be run into one of the tunnels where they remain stationary while drying takes place and from which they are removed for further treatment. The hopper is arranged over the turn-table. Specifications 533,788, 538,024 and 540,530 are referred to.
