Abstract
A method for detaching elastomer particles that adhere on microvalves (3) disposed on the internal surface of a vehicle tire mold (2) comprises vibrating the microvalve (3) at a constant amplitude ranging between approximately 0.05 and 0.2 mm and at a frequency ranging between 20,000 and 30,000 Hz during the detachment of the particles from the microvalve (3).
Claims3
