ABSTRACT:
A ring of paddles is provided the lower ends of which are engageable under the upper bead of a longitudinally-lying tire for lifting the latter and positioning it in a press. The paddles define an enclosure for the press diaphragm to prevent the latter "ballooning" out above a tire or tire carcass pre-formed to C-section and thus of smaller axial extent than its diaphragm when inserted in the press. Spreading of the lower ends of the paddles to engage under the tire bead is effected by gravity as the device is lifted and locking means is provided to prevent such spreading when desired.
