METHOD FOR GUIDING AN ELONGATED ELEMENT FOR A PROCESS FOR OBTAINING VEHICLE WHEEL TYRES AND APPARATUS FOR OBTAINING VEHICLE TYRES

摘要

The present invention is related to a method and an apparatus for obtaining tyres for vehicle wheels, the apparatus comprises a device (11) for dispensing an elongated element (10) and a conveyor (12) for advancing the elongated element (10) towards a forming drum (3, 6). A device (22) for laterally aligning the elongated element (10) is provided which comprises: a pair of counter-facing lateral abutment guides (27a, 27b), each arranged on a respective side of a portion of the supply path, wherein at least one of the lateral abutment guides (27a, 27b) is free to move along a direction (Td) that is transverse with respect to the supply path; at least one weight (33) and transmission elements (31, 32) connecting the weight (33) to the movable lateral abutment guide (27b). The transmission elements (31, 32) are configured to allow the weight (33) to move under the action of the gravity force and to drive the movable lateral abutment guide (27a) therewith along the transverse direction (Td).
