Method and Apparatus for Manufacturing Pneumatic Tyres |
摘要 |
One or more components of elastomer material in a tyre are formed by dispensing elastomer material through a nozzle of an extruder to form a continuous elongated element of flattened section that is laid in the form of coils disposed close to each other on a laying surface carried by a support element, while said support element is driven in rotation and suitably moved adjacent to a die of the nozzle. The nozzle is drivable in rotation by an actuator so as to modify orientation of the nozzle itself during formation of the tyre component.
