    Abstract: A tyre for vehicle wheels includes a tread band having a first annular portion delimited by two circumferential channels. The first annular portion includes two annular grooves extending along respective zig-zag paths. Each of the two annular grooves is defined by a plurality of first parts inclined on one side with respect to a reference plane orthogonal to an equatorial plane of the tyre and by a plurality of second parts inclined with respect to the reference plane on the opposite side to the first parts. Each of the second parts is circumferentially interposed between two respective first parts. Each of the first parts is connected to a respective circumferential channel by a respective first transversal groove arranged at an intermediate portion of the first part and by a respective second transversal groove arranged at an end of the first part.

    Abstract: A tyre includes at least one block on which at least one complex type sipe is obtained separating the block into two portions having a first surface and a second surface facing each other. The first surface is extended between a set of first and second longitudinal sections having, respectively, a first and a second radial profile, which are symmetrical to each other, each one comprising a coupling portion between the two block portions formed by a protrusion and a recess defined by three consecutive inclined lengths, the pattern of which is such that the ends of the coupling portion are offset from each other along a direction transverse to the longitudinal direction of the sipe.

    Abstract: A working station for deposition of elementary semifinished products for building green tyres includes at least one feeding apparatus for feeding an elementary semifinished product, a forming drum, an anthropomorphic robotized arm associated with the forming drum, a control apparatus for sending movement commands to the anthropomorphic robotized arm in order to move the forming drum in a working zone, and a calibration device for calibrating the anthropomorphic robotized arm. The calibration device includes a base plate, a support rotatably mounted on the base plate, and a reference element translatably mounted on the support. The support is positionable in a plurality of first positions relative to the base plate and the reference element is positionable in a plurality of second positions relative to the support and is fixed into one position of the plurality of second positions by inserting at least one pin or screw into one slot of a plurality of slots on the cursor. The control apparatus is also configured for determining target coordinates, retrieving from a memory area a correction function, modifying the target coordinates by means of the correction function, and using processed coordinates for sending the movement commands.
