摘要： A process and an apparatus for cutting a continuous rubber-covered belt in a process for building tyres for vehicle wheels, wherein the apparatus includes a cutting group, in turn comprising: a knife formed by a first half-part and a second half-part and movable along a cutting direction that is tilted with respect to a supply direction of a rubber-covered belt placed beneath the knife. The process includes: lifting a lifting element placed below the continuous rubber-covered belt and at the cutting zone, until a portion of rubber-covered belt is lifted, and lowering the single first-half part of the knife, making it slide with respect to the second half-part.

摘要： A green tyre (2) for bicycles is built, comprising at least one carcass ply (4) having axially opposite end flaps (4a) engaged with respective bead cores (5) and a tread band (6) applied in a radially outer position around said at least one carcass ply (4). The built tyre (2) removed from the building drum, is profiled so as to translate the tread band (6) in a radially outer direction with respect to the bead cores (5), so as to impart a cross-sectional convex profile to the tyre (2) in a radially outer direction. The profiled tire is engaged by means of a transfer member (31) comprising a gripping device (30) which holds it hanging and loads it into a vulcanisation mould (101) by axially positioning an axial centreline plane (M) of the green tyre at an axial reference (51) arranged at a predetermined height along a reference axis (K) of a central body (103) of the vulcanisation mould (101).

摘要： A tyre having a tread is described. The tyre has a central portion located across an equatorial plane, a first shoulder portion located towards an outer side of the tyre and a second shoulder portion located towards an inner side of the tyre. The central portion is separated from the first shoulder portion by two first circumferential grooves. The first shoulder portion and the second shoulder portion have a plurality of first transverse grooves having a first end located substantially at the respective edge of the tread, having a width greater than or equal to about 4 mm and an axial extension equal to at least 50% of the width of the shoulder portion in which they are located.

摘要： A process and an apparatus for automatically applying a noise reducing element to a tyre for vehicle wheels. The process includes: a) providing a noise reducing element; b) providing an adhesive material; c) guiding the noise reducing element according to a predetermined direction; d) during the guiding, applying the adhesive material onto a first surface of the noise reducing element; e) manipulating the noise reducing element by interacting with at least one second surface of the noise reducing element different from the first surface on which the adhesive material has been applied; and f) positioning the noise reducing element in a predetermined position on a radially inner surface of the tyre, bringing the first surface into contact with the radially inner surface.

摘要： A continuous elongated element of elastomeric material is produced through an extruder at a linear delivery speed and directly fed onto a moving surface of a conveyor without interposition of other devices. The continuous elongated element is advanced on the moving surface along a predetermined direction and at a linear advancing speed different from the linear delivery speed until a proximal end of the conveyor. Subsequently, the continuous elongated element is applied onto a forming support which rotates relative to the proximal end of the conveyor at a peripheral speed different from the linear delivery speed, so as to deform the continuous elongated element and apply it in the form of wound coils onto the forming support in order to form a component of elastomeric material of a tyre.
