摘要： A method for controlling the laying down of components of tyres on forming drums, includes: sending a first electromagnetic radiation on a first laying down structure including a forming drum and a first component of a tyre laid down on the forming drum; detecting at least a first corresponding reflected radiation, determining as a function of the first reflected radiation a first parameter representative of a first main length of the first component; comparing the first parameter with one or more pre-stored reference values; generating a first correction signal as a function of the comparison; and sending the first correction signal to at least one preparation station adapted to prepare the first component to regulate the preparation of further components. An apparatus for controlling the laying down of components of tyres on forming drums is also described.

摘要： A process for manufacturing tyres for vehicle wheels, comprising the step of building on a forming support a carcass structure comprising at least one carcass ply and, at at least one end edge of the carcass ply, at least one annular anchoring structure comprising at least one substantially circumferential annular insert and at least one filling insert associated to said at least one substantially circumferential annular insert. The step of building the carcass structure comprises the steps of positioning the annular anchoring structure on the carcass ply by moving the annular substantially circumferential insert into contact with an end edge of the carcass ply by means of a special positioning member, pulling down the filling insert on the end edge of the carcass ply and turning up a free end portion of the end edge of the carcass ply so as to form a turned up end portion of the carcass ply including said annular anchoring structure. The pulling down of the filling insert on the end edge of the carcass ply is carried out by a special pulling down member while the substantially circumferential annular insert is retained into a contact position with the end edge of the carcass ply by said positioning member.

摘要： A tyre for vehicle wheels comprises a support structure and a tread band arranged in a radially outer position with respect to the support structure. The support structure comprises a plurality of hybrid reinforcing cords (10) each having a plurality of monofilament textile wires (20) twisted to at least one multifilament textile yarn (30). In any cross section of the hybrid reinforcing cord (10), at least one portion of at least one monofilament textile wire (20) of said plurality of monofilament textile wires (20) defines a first radially outer surface portion of the hybrid reinforcing cord (10) and at least one portion of said at least one multifilament textile yarn (30) defines a second radially outer surface portion of the hybrid reinforcing cord (10).

摘要： An apparatus for checking tyres has at least one check unit at least two consecutively placed check stations defining a check path such that each check station is traversed in one cycle time and by pitches by each tyre to be checked. Each check station includes: a support device for one tyre at a time housed in the respective check station, high-definition image acquisition systems of a surface of the tyre, and movement devices. The high-definition image acquisition systems have systems for acquiring high-definition two-dimensional and three-dimensional images. Only one of the at least two check stations has all the high-definition three-dimensional image acquisition systems of the check unit.

摘要： A carcass sleeve is situated in a radially external position with respect to a toroidal forming drum, arranged in a first radially contracted operative condition. The carcass sleeve is shaped according to a toroidal configuration while the forming drum is positioned inside the carcass sleeve. During shaping of the carcass sleeve, the forming drum is radially expanded up to a second radially expanded operative condition. Upon completed shaping, the carcass sleeve is coupled to the forming drum in the second operative condition. The forming drum, coupled to the shaped carcass sleeve, is arranged in proximity to at least one device for building at least one belt layer at a radially external position relative to the shaped carcass sleeve.

摘要： A method for controlling the thickness of a continuous elongated element made of elastomeric material, applied according to coils wound on a forming support, includes: advancing a head end of the continuous elongated element toward the forming support; subjecting, during the advancement, the continuous elongated element to a first stretching with a first stretch coefficient before applying on the forming support; and subjecting, during the advancement, the continuous elongated element to a second stretching with a second stretch coefficient during the application on the forming support. During the first stretching, a span of the continuous elongated element adjacent to the head end is stretched with a supplementary stretch coefficient greater than the first stretch coefficient, in a manner so as to confer, also to the span adjacent to the head end, a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element.
