Steel bead heel extraction phase

The steel bead hell extraction of the truck pneumatic is a fundamental phase, before of its entry in the automatized plant. The machine is principally constituted of two oil-dynamic pistons, which opposed do the extraction from the rim zone of two toroidal rings. These are composed of harmonic steel filaments with a thickness of 1.5/2.5 mm that make a bead with an apparent diameter of 20 mm. Upon the machine has been installed an equipment to avert the break of the garter spring; a precaution planned and realized from TIRES SpA , which put an end to a serious working problem. Actually, the common stallonators suffer the break of the garter spring with a frequency of 1/5, without assuring productivity of the machine and making impossible the final steel bead heel extraction of the tyre. The machine has automation through PLC with joystick push-button board, which control simultaneously all the working parameters, assuring the total success.
