Description

(1) Technical field:

[0001] The invention relates to a rubber tire machine, in particular to an automatic turn-up and rolling mechanical forming drum used on a single-stage forming machine of special equipment for producing radial truck tires. (two) background technology:

[0002] Most of the special carcass building drums used in the existing radial truck tire one-step building machine are inflatable capsule turn-up forming drums. During the carcass forming process, compressed air needs to be filled into the capsule to make the capsule expand. It is also necessary to rely on a separate metal structure push plate to compress the deformation of the capsule to complete the turn-up and compaction of the sidewall of the tire. After this operation is completed, the gas in the capsule needs to be discharged to restore the capsule to its original state. In order to carry out the operation of the next molding operation. The waiting time for such operations as inflation, deflation, ...
