Chucks and use in processing toroidal structures

摘要

A chuck and a chuck system, and a method for processing a toroidal structure such as a tire carcass. The carcass includes an internal circumference and tapered ends. The chuck system comprises a plurality of chucks wherein each chuck includes a circumferential or substantially circumferential external surface and a plurality of friction reducing members positioned on the external surface. The friction reducing members are positioned to engage the internal circumference of the toroidal structure such as a tire. The method of processing a tire carcass includes positioning the tire carcass on fixed diameter chucks having friction reducing members on the external surface.
