A tyre building machine (1) comprises a rotatable drum (2), to which strips of material (7) can be applied. Strips of material (7) are transported to the drum (2) by means of conveyors (3). The run of the pieces of material (7) transversely in relation to the running direction is sensed by means of a first sensor (9) and fed to a position controlling device (12). To compensate for machine- or transfer-induced errors, at least one second sensor (16), which senses the position of the strip of material (7) transversely in relation to the running direction, is provided in the region of the drum (2). An output signal of this second sensor (16) is in operative connection with the position controlling device (12) to correct the setpoint value correspondingly (FIG. 1).
Method for building a tyre, in which strips of material (7) are fed by conveyors (3) to at least one drum (2) and led through a position control transversely in relation to their running direction, to be subsequently applied to the drum (2), the position of the strips of material (7) on the drum (2) transversely in relation to the running direction being sensed and compared with a setpoint value, and the result of the comparison being entered in the position control of at least one of the conveyors (3), characterized in that the position of the strip of material (7), the result of the comparison and/or the output signal of the controller (15) is stored, with the stored signal acting on the position control of the conveyor (3) at the earliest when the next strip of material (7) is fed in by the same conveyor.
Tyre building machine comprising a rotatable drum (2), to which strips of material (7) that can be transported to the drum (2) by means of conveyors (3) can be applied, the run of the strips of material (7) transversely in relation to the running direction being sensed by at least one first sensor (9), which is in operative connection with a position controlling device, with at least one second sensor (16), which is in operative connection with the position controlling device (12) and senses the position of the strip of material (7) transversely in relation to the running direction, being provided in the region of the drum (2), characterized in that the at least one second sensor (16) is in operative connection with first storing means (30), which are in operative connection on the output side with at least one multiplexer (29), which feeds the stored signals to storing means (30) that are assigned to the conveyors (3) and the stored signals of which act on the position control of the conveyor (3) at the earliest when the next strip of material (7) is fed in by the same conveyor.
