    摘要： Method for controlling the extrusion of a semifinished product in a tyre building process, said method comprising: providing a semifinished product (1) at the exit of an extrusion assembly (2), said semifinished product (1) comprising at least: a first component (11) made of at least one first material; a second component (12) made of at least one second material, different from said first material; said semifinished product (1) having accumulated heat during an extrusion carried out in said extrusion assembly (2); making a first verification for verifying at least one of: presence of said second component (12) and arrangement of said second component (12) relative to said first component (11), wherein said first verification comprises: detecting first electromagnetic radiations (Rl) representative of a heat emission from said semifinished product (1) while said semifinished product (1) is releasing said accumulated heat; based on said first radiations (Rl) detected, determining first detection parameters (DPI) representative of at least one of the presence of said second component (12) and/or the arrangement of said second component (12) relative to said first component (11); generating a first notification signal (NS1) as a function of said first detection parameters (DPI). An apparatus (100) is also described for controlling the extrusion of a semifinished product in a tyre building process.

    摘要： An apparatus (1 ) for controlling tyres comprises a support plane (2) configured for receiving a tyre (3) with axial middle line plane (4) parallel to the support plane, defining an abutted lateral portion (10a) and a free lateral portion (10b) arranged at a specific height with respect to the support plane. A thrust element (23) is configured for applying, to a measurement surface of the free lateral portion (10b), a force (F) directed towards the support plane. A positioning actuator (19) is operatively associated with the thrust element (23) and configured for moving the thrust element (23) with at least one motion component perpendicular to a rotation axis (X) of the tyre. The apparatus also comprises devices for modifying the angular position of the measurement surface. A control unit is programmed for detecting a first value (U1 ) of output data at each position of the measurement surface as a function of a first value (11 ) of input data maintained substantially constant along at least one complete rotation of the measurement surface around the rotation axis (X) and for detecting a second value (U2) of the output data at each position of the measurement surface. The second value (U2) of the output data corresponds with a second value (I2) of the input data maintained substantially constant along at least one complete rotation of the measurement surface. The control unit comprises a module programmed for calculating, at each position of the measurement surface, a difference (D) between the second value (U2) of the output data and the first value (U1 ) of the output data.
