Abstract

<PICT:0492372/IV/1> <PICT:0492372/IV/2> Apparatus for the production of foils, films, &c. by the coagulation method comprises an endless belt on to which the film-forming solution is poured, the belt being carried by three or more guide drums arranged so as to provide an upper horizontal run on to which the solution is poured, and so as to guide the band at least for the first part of its travel in the bath and for the major part of such travel in sum in an inclined direction. Typical arrangements are shown in Figs. 1 and 3, in which the belt e is supported by drums a, b, c, is coated from a pourer g and is guided in a bath f, the film being stripped off at the point h. The bath f may be enclosed for the purpose of exhausting vapours.
