摘要： In a process for building tyres for vehicle wheels, the building of a belt structure of a crown structure comprises: sequentially depositing, on a first conveyor belt (11a), a predetermined number of strip-like elements; sequentially depositing, on a second conveyor belt (lib), a predetermined number of strip-like elements; transferring the strip-like elements from the first conveyor belt (11a) to a forming support (100) for building a first belt layer on the forming support (100); moving the forming support (100) at the second conveyor belt (11b); transferring the strip¬ like elements from the second conveyor belt (lib) to the forming support (100) for building a second belt layer on the forming support (100) in a radially outer position with respect to the first belt layer. Transferring the strip- like elements from the first conveyor belt to the forming support (100) is at least partially carried out simultaneously with at least part of depositing the strip- like elements on the second conveyor belt (11b).

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, comprises: advancing a head end (54) of the continuous elongated element (21) towards the forming support (11, 16); subjecting - during the advancement - the continuous elongated element (21) to a first stretching with a first stretch coefficient (K 1 ) before applying on the forming support (11, 16); subjecting - during the advancement - the continuous elongated element (21) to a second stretching with a second stretch coefficient (K 2 ) during the application on the forming support (11, 16). During the first stretching, a span (55) of the continuous elongated element (21) adjacent to the head end (54) is stretched with a supplementary stretch coefficient (K' 1 ) greater than the first stretch coefficient (K 1 ), in a manner so as to confer, also to the span (55) adjacent to the head end (54), a stretch and a section similar or substantially equivalent to those of the rest of the continuous elongated element (21) .

摘要： In the manufacturing of a semi - finished product (100) made of elastomeric material, a method is carried out for controlling the heating of an extrusion device (1) comprising multiple structural units (10-40) having respective different working temperatures (T1-T4)and thermal inertias (11-14). The method comprises: a) setting, for all of the above-mentioned units (10-40, a heating temperature to a value equal or close to the working temperature of the unit which has the lowest working temperature; b) simultaneously heating all of the above-mentioned units (10-40); c) when said unit is approaching or has reached said heating temperature, setting for the other units a new heating temperature to a value equal or close to that of the working temperature of the unit whose working temperature is closest to said heating temperature; d) iteratively repeating the operations mentioned in b) and c), until all of the above- mentioned units (10-40)have reached the respective working temperature (T1-T4).
