- a further embodiment of the invention is a plurality of rotary nozzle devices the roll surface across the entire roll width distributed.
- the at least a rotating nozzle device on a traversing trolley arranged in the longitudinal direction of the Roller is traversable back and forth.
- This measure has the advantage that additional superimposition with the speed component of the traversing carriage moving back and forth a further intensification of Cleaning effect is achieved. Furthermore are fewer rotating nozzle devices required to to clean the entire roller surface. To this In addition, the consumption of cleaning fluid be restricted.
- the flushing device arranged behind the high-pressure spray device in the direction of rotation of the roller ensures that of the High pressure sprayer, which either as Needle spray pipe or as a rotating nozzle device detached impurities can be suspended and lighter from the roller surface can be removed.
- This flushing device is expediently used as Flat jet spray tube, which is parallel to Roll surface extends in the longitudinal direction of the roller.
