Claims5
A differential rewinding apparatus comprising a shaft on which, in use, a plurality of cores are mounted, a plurality of apertures in the shaft, roller elements in the apertures and means for urging the roller elements outwardly into engagement with the cores, and in which each of the roller elements is arranged to act between a core and a torque-transfer element formed of a material which has a coefficient of sliding friction with the roller elements lower than the coefficient of sliding friction between the roller elements and the cores.
