Abstract

396,036. Moulding plastic sheets. ROUX, B., 142, Rue du Chemin Vert, Paris. Oct. 24, 1931, No. 29577. Convention date, Oct. 24, 1930. Void [Published under Sect. 91 of the Acts]. [Class 87 (ii).] In stamping thin sheets of celluloid, synthetic resin, &c. such as for gramophone records, the stamping pressure is applied directly to the matrix E by a fluid. The matrix E is resilient and is formed as one wall of a closed pressure chamber F and is adapted to be held abutting against a thin sheet G between the plates A, D of an hydraulic or other press. The chamber is then filled with fluid under pressure so that the sheet is impressed. The sheet may be placed between two chambers, or a second matrix C may be placed on the other side between the sheet and the plate A as shown. The pressure is increased to 100 kg. per sq. cm. at a temperature of 100‹ C. The apparatus is then cooled by circulating water, and the press finally released. Auxiliary heating coils may be provided in the chambers. Water, air, steam or other fluid may be used. French Specification 544,942 is referred to.
