Abstract
A process and apparatus for cleaning a transport belt of a machine for the production or processing a web. The apparatus includes at least one nozzle device composed of a rotatable nozzle head having at least one cleaning nozzle, a transport device including a crosspiece extending substantially crosswise to a transport belt travel direction, in which the at least one nozzle device is coupled to the transport device and adapted for displacement along the crosspiece. A traversing speed of the nozzle device is very low and falls within a range of between approximately 1 mm/min and 10 mm/min. Alternatively, the at least one nozzle is positionable in a plurality of cleaning positions that are successively arranged crosswise to the transport belt, and the at least one nozzle is held stationary in each respective cleaning position for a predefined time period. The process includes displacing the at least one cleaning nozzle at a very slow traversing speed within a range of between approximately 1 mm/min and 10 mm/min. Alternatively, the process includes discontinuously moving the at least one cleaning nozzle to a plurality of cleaning positions successively arranged in a transport belt travel direction, positioning the at least one nozzle to remain in the cleaning positions for a predefined period of time, and rapidly displacing the at least one nozzle between adjacent cleaning positions.
