1. Patentansprak: 1:o) Salt att framstalla eldfast Dapper, papp och dylika fiberprodukter genom impregnermg med vattenglas, varvid en suspension av fibrerna avvattnas p& en vira eller avvattningscylinder och darefter det shlunda avvattnade fiberskiktet torkas ph en torkanordning, kannetecknat darav, att vattenglaslosningen tillf0- res fibermassan efter det denna inforts ph% vi-ran eller avvattningscylindern och innan fiberskiktet torkas & torkanordningen. 2:o) Satt enligt patentanspriket 1:o), kannetecknat darav, att vattenglaslosningen i Lint fordelat slick sprides Over fibermassan, medan denna befinner sig pa viran resp. avvattningscylindern. 3:o) Satt enligt patentansprhket 1:o), Iannetecknat darav, att forutom vattenglas alkaliklorid tillfOres fibermassan. Stockholm 1940. Rungl. Soktr. P. A. Nocatedt & Winer 400089Patent claim: 1: o) Salt for the production of refractory Dapper, cardboard and similar fibrous products by impregnation with water glass, a suspension of the fibers being dewatered on a wire or dewatering cylinder and then the thus dewatered fibrous layer being dried on a drying device, characterized in that the water glass the fibrous mass is supplied after it has been introduced into the ph% wire or the dewatering cylinder and before the fibrous layer is dried & the drying device. 2: o) Set according to patent claim 1: o), can be characterized by the fact that the water glass solution in Lint distributed sludge is spread over the fibrous mass, while this is on the wire resp. the drainage cylinder. 3: o) Set according to patent claim 1: o), characterized in that in addition to water glass alkali chloride, the fibrous mass is supplied.
