1,178,388. Impregnation, fabric with resin. BRISTOL AEROPLANE PLASTICS Ltd. 19 July, 1967 [20 July, 1966], No. 32629/66. Heading D1L. Fabric 6 is impregnated by resins in tray 17 by passage over a series of rollers 1 (partially immersed in the resin) and under pressure rollers 11, the latter determining the amount of resin left in the web. A further quantity of resin overflows 21 and forms an additional coating on the web. The web is fed from a heated roll 2. A doctor blade, not shown, may be used to control the amount of resin impregnated. The rollers 1 are made so that they can be removed to alter the impregnating effect. |
