Abstract

284,725. Sindl, O. Feb. 5, 1927, [Convention date]. Apparatus for making films.-The cellulose solution is delivered, in the form of a film, from a nozzle 3 on to a moving sheet or film of coagulating-fluid supplied from a nozzle 2, so as to effect the coagulation of one side of the film only, whereby gases produced during the coagulation process can escape through the uncoagulated side of the film. The film of coagulating-liquid flows over an inclined surface 1 of glass, porcelain &c., and the partly-coagulated cellulose film 6 is passed into a bath 8 of the coagulating- liquid, conveniently by means of a roller 7, in order to complete the coagulation process.
