Title (EN) WORKPIECE HOLDER
(FR) SUPPORT DE PIECE
Abstract: front page image
(EN)A workpiece holder for supporting an annular workpiece (34) such as a tire for a vehicle. The holder (10) includes a plurality of elements (27) movable radially outwardly into engagement with an inner surface of an annular workpiece (34) in response to movement of a cam (32). The gripping force applied to the inner surface of the tire by this arrangement is only slightly greater than that required to support the tire carcass thus overcoming the problem of core breakage.
(FR)Support de piece servant a tenir une piece annulaire (34) tel qu"un pneu d"un vehicule. Le support (10) comprend une pluralite d"elements (27) amovibles radialement vers l"exterieur en prise avec Ia surface interne d"une piece annulaire (34) par reaction au mouvement d"une came (32). La force de serrage appliquee sur la surface interne du pneu avec ce dispositif n"est que legerement superieure a celle requise pour soutenir la carcasse du pneu, ce qui resout le probleme de la rupture du noyau.
