Abstract

1,260,513. Moulding rubber-bonded fibre sheets. FRENZELIT ASBESTWERKE G.m.b.H. & CO. K.G. 19 March, 1969 [20 March, 1968], No. 14382/69. Heading B5A. A method of manufacturing natural or synthetic rubber-bonded fibre sheets comprises calendering a mixture of the fibres, rubber and a solvent by passage through the nip of a heated roller 1 and a cooled roller 2 biased towards roller 1, the latter carrying a band 4 of high tensile steel which passes under tension around a further roller 3, solvent vapour given off during calendering being recovered from a casing (not shown) enclosing the apparatus. Further roller 3 may be heated and may be associated with a cooled roller 6 and run of band 4 between rollers 1 and 3 may be heated, e.g. by induction or radiation. The preferred fibres are of asbestos, but may be of glass, slag or rock wool. A comparative example is given.
