摘要： The invention relates to a device for producing a tyre reinforcing structure comprising wires which are disposed essentially parallel to one another, said device being intended to be used together with an essentially-toroidal element (1). According to the invention, the reinforcing structure is constructed gradually on the aforementioned toroidal element (1) by depositing hoops of wire side-by-side on the surface of the toroidal element along the desired trajectory for said wire. The inventive device consists of an assembler (5) comprising: an inlet which is used to receive the wires (2); a gumming chamber (50); a positive-displacement pump which is used to deliver a rubber composition inside the gumming chamber; and a strip delivery outlet (20), said strip comprising the wires which are connected by said rubber composition. The invention also includes a strip depositing device (4) comprising a reference frame in relation to which the toroidal element can be installed at a known position.

摘要： During the production of a tyre, a belt structure is formed by means of band-like portions (5) each comprising parallel cords (16) incorporated in an elastomer layer and sequentially laid in a mutually circumferentially adjacent arrangement on a toroidal support (3). According to the invention, the band-like portions (5) are applied with at least one of the smaller sides circumferentially non-aligned with the corresponding smaller side of at least one of the circumferentially adjacent band-like portions (5), so that said cords (16) in the side zones of the belt structure of the radial tyre thus obtained have a non-uniform density.

摘要： The present invention is related to a process and apparatus for manufacturing tyres for vehicle wheels. At least one of the components of the green tyre (100) is formed by supplying an elongated element (14) made of elastomeric material along a feed path. A piece (57) is cut from a head section of the elongated element (14), advanced on a conveyor (11 b) up to a forming drum (3) and deposited on a radially outer surface (3a) of the forming drum (3). The cutting comprises: depositing, between an abutment surface (32) and a coupling surface (42, 46) that are opposite each other, each of two portions (T, H) of the elongated element (14) situated on opposite sides of a transverse cutting line (S); cutting the elongated element (14) along such transverse cutting line (S) while the two portions (T, H) are arranged between said abutmenht surface (32) and said coupling surface (42,46).
