Abstract (en)
Rotary-belt printing machine comprising a powered rotary belt (11) to bring segments thereof opposite printing stations (13). A control device (16) for accurate positioning of the belt (11) receives signals from an optical sensor (15) arranged near a lateral edge of the belt to detect the sequential passage under it of marks (14) arranged along the belt edge. The control device 16 processes the signals of the sensor (15) as feedback for correct and accurate positioning of the belt (11). The sensor is a linear sensor (15) with detection line arranged parallel to the lateral edge of the belt (11) to detect the position of marks (14) in its field of vision and permit accurate stopping of the belt in a position corresponding to a mark positioned in a particular position in said field of vision. <IMAGE>
