A conveying installation has least one endless conveyor belt guided via a plurality of rollers along a leading belt run for conveying material or products and a returning belt run, particularly for manufacturing a paper web with a wire belt or felt belt. At least one of the rollers has an adjustable mounting for adjusting and correcting a direction of movement of the conveyor belt. A tensioning unit for detecting and controlling a tension of the conveyor belt has a pressure-measuring apparatus disposed at the adjustable mounting. A movement correction unit for detecting deviations of a direction of movement of the conveyor belt from a correct movement and for correcting the movement includes a sensor that is disposed to monitor a lateral periphery of the conveyor belt. A sensor output of the sensor is used for adjusting the adjustable mounting of the one of the rollers.
