Abstract
1,051,414. Making inner tubes. DUNLOP RUBBER CO. Ltd. Feb. 12, 1964 [Feb. 25, 1963], No. 5810/64. Heading B5A. [Also in Division B7] Tyre inner tubes (see Division B7) are formed from tubular lengths of unvulcanized rubber which are extruded from an extruder 6 comprising a screw 7 disposed within a passageway 8, the passageway having an inlet 9 at one end and, at the other end, an annular die orifice 10 defined by the wall of the passageway and a central die part 11 secured radially within and spaced from the wall of the passageway. During extrusion, the inner surface of the formed tubular length is powdered with zinc stearate to prevent opposing sides of the inner surface adhering together.
