Abstract
867,294. Re-treading tyres. HAMMESFAHR, G. Nov. 23, 1959, No. 39631/59. Class 87(2). [Also in Group XXXIV] In the re-treading of a tyre, a cover plate 6 on a mould 3 is first raised above a spreader 2, and the tyre placed on the spreader. The tyre is then spread, the mould containing the retreading material is raised to the spreader, the spreader retracted and the mould containing the tyre lowered, until the lower bead rests on a ring 5. The cover plate 6 is lowered on to the tyre and the assembly locked together e.g. by pawls on the cover plate engaging recesses in the plate 4. A curing bag 8 is inserted into the tyre by a piston rod 7a, and is then inflated whilst the mould is heated. After vulcanization the tyre is removed from the mould by a reverse process. In a modification, the mould may be stationary and the other parts movable. Various forms of bag are shown, e.g., as shown in Fig. 2a, the bag may be screwed at its edges 8a, 8b to plates 15a, 15b, or for tubeless tyres the bag may be dispensed with, the beads being sealed by plates 15a, 15b, Fig. 5.
