1. A former (1) on which elongate material, such as tyre bead wire, can be wound into a plurality of convolutions, the former 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 being movable into their inner positions to facilitate removal of the wound elongate material from the former, and moving means (5-13) for moving the movable segments (20-23) between their inner and outer positions, characterised in that the moving means includes control means (5) for controlling the radial movement of each of said segments (20-23) so that the segments, when in their inner positions, partly overlap one another, and, when in their outer positions, are arranged so that the at least one groove (30,31) in which the elongate material is wound in a plurality of convolutions is at least substantially continuous.
