Die Reinigungsvorrichtung weist hierzu einen Halter für das die Aufnahme ADl darstellende Rohr des Düsenstreifens D auf. Before the first cleaning operation, a jet strip D developed from a nozzle bar of a system, not shown, is provided in a receptacle AD1 in the area of the transport rollers TE. For this purpose, the cleaning device has a holder for the tube of the nozzle strip D which represents the receptacle AD1.
Der Düsenstreifen D wird von einer Bedienperson aus der Aufnahme ADl herausgezogen und in den Spalt der Transportrollen TE zugeführt. Diese fördern den Düsenstreifen D nun in Pfeilrichtung durch die Reinigungsvorrichtung, bis der Streifen D von dem zweiten Transportrollenpaar TA erfasst und vollständig aus der Reinigungsvorrichtung heraus und in die Aufnahme AD2 gefördert wird. Stellt die Bedienperson mittels der Beleuchtungseinrichtung BE fest, dass eine weitere Reinigung nötig ist, so wird der Vorgang wiederholt und der Düsenstreifen D von der Aufnahme AD2 in den Spalt des Transportrollenpaares TA geführt. Der Düsenstreifen D läuft nun wieder durch die Reinigungsvorrichtung in die Aufnahme ADl und von dort wieder zurück in Richtung zweite Aufnahme AD2. So erfolgt nach dem Durchlaufen des Streifens D durch die Zonen der Hochdruckdüsen DO, DU auch ein Trockenblasen. Bezugszeichenliste: The nozzle strip D is pulled out of the receptacle AD1 by an operator and fed into the gap of the transport rollers TE. These convey the nozzle strip D now in the direction of the arrow through the cleaning device until the strip D is detected by the second pair of transport rollers TA and is completely conveyed out of the cleaning device and into the receptacle AD2. If the operator determines, by means of the illumination device BE, that further cleaning is necessary, the process is repeated and the nozzle strip D is guided by the receptacle AD2 into the gap of the transport roller pair TA. The nozzle strip D now runs again through the cleaning device into the receptacle AD1 and from there back toward the second receptacle AD2. Thus, after passing through the strip D through the zones of the high-pressure nozzles DO, DU, a dry blowing takes place. LIST OF REFERENCE NUMBERS
