A METHOD AND APPARATUS FOR MANUFACTURING ELASTOMERIC MATERIAL COMPONENTS OF A TYRE FOR VEHICLE WHEELS

摘要

A method and apparatus for manufacturing elastomeric components of a tyre, said method comprising: feeding a continuous elongated element (20) from a delivery member (19) disposed close to a toroidal support (18) for application of said elongated element (20) onto the toroidal support itself; giving the toroidal support (18) a rotatory motion for circumferential distribution around its geometrical rotation axis (X) ; moving said toroidal support (18) on a plurality of axes so as to carry out controlled relative displacements for transverse distribution between said toroidal support (18) and said delivery member (19) to form a component (9, 12, 13, 14, 15, 16, 17) of a tyre (3) with said elongated element (20) which is defined by a plurality of coils (20a) laid down in mutual side by side and superposed relationship in a pre-established deposition pattern depending on a predetermined cross-section outline to be given to said component (9, 12, 13, 14, 15, 16, 17), wherein a step of signalling the presence of said elongated element (20) coming out of said delivery member (19) is provided.
