    摘要： A method and an apparatus for producing tire bead cores, in which a bead wire extending tangentially relative to a bead core winding drum is guided by a guide means that extends radially relative to the winding drum, and the guide means is moved toward clamp jaws of a chuck to cause a translation movement of the bead wire to a position between the clamp jaws, for clamping a leading end of the bead wire by the chuck. The winding drum is rotated together with the chuck so that the bead wire with its leading end clamped by the chuck is helically wound in a circumferential groove of the winding drum as a plurality of layers, thereby forming a bead core having a predetermined cross-section. The segments are then synchronously moved radially inwards, so as to reduce an outer diameter of the winding drum to a value smaller than the inner diameter of the bead core.

    摘要： A former (1) on which elongate material, such as tyre bead wire, can be wound, comprising a plurality of grooved segments (20-23), each movable radially between inner and outer positions and which, when in their outer positions, together define the entire periphery of the former and provide at least one groove (30,31) in which the elongate material can be wound in a plurality of convolutions, the segments (20-23) being movable into their inner positions to facilitate the removal of the wound elongate material from the former, and moving means (5-13) for moving the movable segments between their inner and outer positions. The segments (20-23), when in their inner positions, overlap one another and, when in their outer positions, have little or no gaps therebetween so that the or each circumferential groove is continuous. The invention also relates to a former (1) having a gripping device and to a guide assembly (80) for guiding elongate material.
