Inflatable, ring-shaped, tubular bladder for use in tyre production, e.g. for cambering or clamping, comprises rubber layers and rubberised reinforcing layers containing anisotropically-arranged short fibres

摘要

An inflatable, ring-shaped tubular cambering bladder (1), especially for tyre production machines (2), consisting of rubber layers (5, 6) and reinforced with rubberised stress-bearing layer(s) (5) with stress carriers (6) at right angles to the axis of the ring (4) and parallel to its circumferential profile, in which the stress carriers (6) in the stress-bearing layers (5) comprise short fibres arranged anisotropically in the rubberised layer(s) (5).
