发明名称 PROCESS AND APPARATUS FOR UNWINDING AN ELONGATED ELEMENT PROVIDED WITH TWO SERVICE FABRICS IN ORDER TO BUILD TYRES FOR VEHICLE WHEELS
摘要 A process for building tyres for vehicle wheels includes feeding to at least one work station an elongated element provided with two service fabrics and wound on a storage coil. The aforementioned feeding includes unwinding the elongated element from the storage coil, removing the two service fabrics from the elongated element, and collecting each of the two service fabrics on a respective collecting member. Each service fabric can thus be subsequently used independently from the other. For example, one service fabric can be reused while the other can be disposed. The removal and collection of the two service fabrics occurs simultaneously with the unwinding of the elongated element, so as not to increase the overall building time of the tyre being processed.
