PROCESS AND APPARATUS FOR MANUFACTURING A REINFORCING STRUCTURE OF A TYRE FOR VEHICLE WHEELS

摘要

The present invention relates to a process for manufacturing a reinforcing structure of a tyre for vehicle wheels, on a toroidal support comprising an outer surface, by means of at least one laying element (6), which can be oriented in space in a controlled way; said laying element (6) comprising a laying surface adapted to act on a portion of a rubberized strip-like element (5) for laying the same on the outer surface (3a) of the toroidal support; the reinforcing structure comprises at least a first and a second radially superimposed reinforcing layers each comprising a plurality of strip-like elements (5); each reinforcing layer has a circumferential extension about a rotation axis of the tyre and comprises thread-like reinforcing elements, arranged parallel to one another; the layers are arranged so that the reinforcing thread-like elements of the first reinforcing layer are oriented obliquely with respect to the equatorial plane (Y-Y) of the tyre, and that the reinforcing thread-like elements of the second reinforcing layer also have an oblique orientation, crossed with respect to the thread-like elements of the first layer.
