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

摘要

A method for manufacturing elastomeric material components of a tyre for a vehicle wheel includes feeding a continuous elongated element from a delivery member for application onto a support, giving the support a rotary motion around a geometrical rotation axis of the support, so that the elongated element is circumferentially distributed on the support, and carrying out controlled relative displacements for transverse distribution between the support and the delivery member to form the elastomeric material components of the tyre with the elongated element. Feeding the elongated element takes place by extrusion of elastomeric material through at least one extrusion screw and at least one gear pump. The component is defined by a plurality of coils laid down in a pre-established deposition pattern depending on a cross-section outline to be given to the component. An apparatus for manufacturing elastomeric material components of a tyre for a vehicle wheel is also disclosed.
