Abstract

1,150,545. Gramophone-record presses. TELDEC TELEFUNKEN-DECCA SCHALLPLATTEN G.m.b.H. 13 May, 1966 [13 May, 1965], No. 21336/66. Heading B5A. Lateral displacement between the rams of a gramophone-record press is compensated by the interposition of a resilient layer (15) between the lower movable platen (14) and the lower die of the press. The resilient layer (15) may comprise a layer of rubber or several such layers spaced apart by sheet metal strips (32) (Fig. 6) or a " hydraulic cushion " comprising a diaphragm (20) and a cavity (21) which is filled with a liquid (Fig. 5).
