PROCESS AND APPARATUS FOR MANUFACTURING A REINFORCING STRUCTURE FOR TYRES OF VEHICLES

摘要

In tyre manufacture, a belt structure (2) is made by means of strip-like segments (5) each comprising parallel cords incorporated into an elastomeric layer, which strip-like segments (5) are sequentially laid down in mutual circumferential side by side relationship on a toroidal support (3). The apparatus for manufacturing such a reinforcing structure for vehicle tyres comprises: - a laying unit (100) comprising at least one laying assembly (9, 91) designed to apply each of said strip- like elements (5) onto a toroidal support (3), according to a predetermined laying angle (a) relative to a circumferential extension direction of the toroidal support itself; -said laying assembly (9, 9') comprising at least a first presser element (14), movable in contrast relationship against the outer surface (3a) of the toroidal support (3); said first presser element (14) comprises at least one tapered end (31) adapted to perform said contrast relationship and forming a tilted side (32) according to a tilt angle (ß) correspondent to said predetermined laying angle (a) of the strip-like elements.
