Abstract

<PICT:0924578/IV(a)/1> A process for coating webs or strips B of heatresistant material on one side only, comprises guiding two webs or strips of equal width, disposed back to back, through a heating apparatus 1 and a sintering apparatus 2 which has a fluidized bed of powdered, thermoplastic coating material. The webs, which may be of metal or a textile fabric or a fleece, e.g. of glass or asbestos fibres, are fed by rollers 5 horizontally or vertically through the apparatus 2, sealing chambers, as 4, employing air or gas streams, being provided. The webs, if of metal, may be pretreated by phosphating, pickling or chromating to promote adhesion, and are heated to 120 DEG to 450 DEG C. in the apparatus, which may have infra red heaters. Rolls 51, rotating faster than the rolls 5, draw the coated webs under tension out of the apparatus 2, and lead them, if desired, to heating apparatus 3. Some or all of the rolls employed within and without the apparatus 1, 2, 3 may be heated or cooled.
