Description

Die Erfindung betrifft eine Bestäubungsanordnung in einer Druckmaschine mit wenigstens einer Reihe von sich über die Bedruckstoffbreite erstreckenden Bestäubungsdüsen nach dem Oberbegriff des Hauptanspruches.The invention relates to a pollination arrangement in a printing press with at least a series of dusting nozzles across the width of the substrate after the Preamble of the main claim.

Eine Bestäubungsanordnung dieser Art zur Puderbestäubung von frisch bedruckten Bogen ist aus der DE 22 07 983 B2 bekannt. Die Einrichtung soll das Ausstäuben von Puder über die Grenzen des Wirkungsbereiches hinaus verhindern und eine Puderrückgewinnung ermöglichen. Oberhalb der Bogenförderebene ist ein Puderzuführrohr angeordnet aus dem mittels Druckluft Puder auf den Bogen aufgestäubt wird. In Bogenförderrichtung vor und nach dem Puderzuführrohr ist als Blasvorhang je ein Blasrohr mit zugeordnetem Saugrohr angeordnet, durch das überschüssiger Puder absaugbar ist. Die Austrittsöffnungen der Austrittsdüsen sind zur Bogenförderebene im rechten Winkel, d.h. senkrecht zur Bogenförderebene, angeordnet.A pollination arrangement of this type for powder pollination of freshly printed sheets is known from DE 22 07 983 B2. The facility is said to be dusting over powder prevent the limits of the effective range and enable powder recovery. A powder feed pipe is arranged above the sheet conveying plane powder is sprayed onto the sheet using compressed air. In the sheet conveying direction in front and after the powder feed tube there is a blow tube with an associated suction tube as a blow curtain arranged through which excess powder can be sucked off. The outlet openings of the outlet nozzles are at right angles to the sheet conveying plane, i.e. perpendicular to the sheet conveying plane, arranged.

Aus der DE 42 07 118 A1 ist unter anderem bekannt, daß ein Puderkasten in Förderrichtung nach der Puderdüsenanordnung einen größeren Abstand als vor dieser aufweist. Dabei ist in Förderrichtung nach der Puderanordnung eine Luftdüsenanordnung vorhanden, deren Blasluft entgegen der Förderrichtung strömt.From DE 42 07 118 A1 it is known, among other things, that a powder box in the conveying direction after the powder nozzle arrangement has a larger distance than before this. Here there is an air nozzle arrangement in the conveying direction after the powder arrangement Blown air flows against the conveying direction.

Weiterhin ist aus dem DE 295 17 283 U1 eine Pudereinrichtung im Ausleger einer Druckmaschine bekannt. Die Einrichtung besitzt ein Gebläse, vorzugsweise einen Axialventilator, auf, das einen senkrecht auf die Bogenförderebene gerichteten Luftstrom erzeugt, wobei die Puderdüsen in diesem Luftstrom angeordnet sind. Furthermore, DE 295 17 283 U1 describes a powder device in the delivery of a printing press known. The device has a blower, preferably an axial fan, on, which generates an air stream directed perpendicular to the sheet conveying plane, wherein the powder nozzles are arranged in this air flow.

Nachteilig bei diesen Ausführungen ist es, daß das unkontrollierte Austreten von Bestäubungsmaterial in die Druckmaschine, insbesondere im Bogenausleger, nicht ausreichend verhindert wird. Dies führt zu Maschinenverschmutzungen, die durch ein zu üppiges Dosieren von Bestäubungsmaterial noch verstärkt werden. Die Verwendung von Blas- und Saugrohren als Luftvorhang schafft zusätzliche Turbulenzen, die in Verbindung mit den vorbeilaufenden Greifersystemen während des Bestäubungsprozesses noch verstärkt werden. Weiterhin verschlechtert sich insbesondere bei höheren Maschinengeschwindigkeiten (> 8.000 Bogen/Stunde) die im Bestäubungsprozeß erzielbare Qualität durch zunehmende Turbulenzen. So sind häufig die im Greiferschluß fixierten bogenförmigen Bedruckstoffe im Bereich der Vorderkante ungenügend bestäubt, was zum Ablegen der Bedruckstoffe an der Vorderkante im Auslegerstapel führt.A disadvantage of these designs is that the uncontrolled leakage of pollination material in the press, especially in the sheet delivery, not sufficient is prevented. This leads to machine contamination caused by excessive metering pollination material. The use of blow and suction pipes As an air curtain creates additional turbulence in connection with the passing ones Gripper systems are further reinforced during the pollination process. Furthermore it deteriorates especially at higher machine speeds (> 8,000 sheets / hour) the quality that can be achieved in the pollination process by increasing Turbulence. For example, the sheet-like substrates fixed in the gripper closure are often in the Inadequate dusting in the area of the leading edge, which leads to the printing materials being deposited on the Leading edge in the boom stack.

Aufgabe der Erfindung ist es, eine Bestäubungsanordnung zu schaffen, die die genannten Nachteile vermeidet, die insbesondere eine gleichmäßigere Bestäubung der Bedruckstoffe erzielt und den Verbrauch an Bestäubungsmaterial spürbar reduziert.The object of the invention is to provide a pollination arrangement, the said Avoids disadvantages, in particular a more uniform pollination of the substrates achieved and the consumption of pollination material noticeably reduced.

Die Aufgabe wird erfindungsgemäß durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.
Die sich quer zur maximalen Bedruckstoffbreite erstreckenden Austrittsdüsen der Bestäubungseinrichtungen sind, bezogen auf die Bedruckstoff-Förderebene, in Förderrichtung des Bedruckstoffes vorzugsweise in einem spitzen Winkel α geneigt angeordnet, wobei als Sonderfall auch der Winkel α = 0 gilt.
Die durch die Bestäubungseinrichtung erzeugte Volumenströmung, gebildet aus Bestäubungsmaterial und Druckluft, trifft insbesondere geneigt in Förderrichtung des Bedruckstoffes auf dessen Oberfläche auf. Damit wird auch der bisher vom Greifersystem verdeckte Bereich an der Vorderkante des Bedruckstoffes gleichmäßiger bestäubt und das Ablegen im Auslegerstapel vermieden.
The object is achieved by the training features of the main claim. Further training results from the subclaims.
The outlet nozzles of the dusting devices, which extend transversely to the maximum substrate width, are preferably inclined at an acute angle α in the conveying direction of the substrate, with reference to the substrate conveying plane, the angle α = 0 also being a special case.
The volume flow generated by the dusting device, formed from dusting material and compressed air, strikes the surface of the printing material in particular inclined in the conveying direction. This also means that the area on the front edge of the printing material that was previously covered by the gripper system is dusted more evenly and storage in the delivery stack is avoided.

Weiterhin sind den Austrittsdüsen mehrere bewegbare Absaugelemente einer Absaugeinrichtung zugeordnet, durch die das Bestäubungsmaterial direkt an den Austrittsöffnungen der Düsen auswählbar gesteuert absaugbar ist. Das abgesaugte Bestäubungsmaterial ist in einem Kreislauf der Bestäubungseinrichtung wieder zuführbar. Eine Wiederaufbereitung des Bestäubungsmaterials innerhalb des Kreislaufes ist in der Regel nicht erforderlich, da das Bestäubungsmaterial direkt an den Austrittsöffnungen der Düsen abgesaugt wird und somit keinen spürbaren Kontakt mit Farbe, Papierstaub oder Luftfeuchtigkeit erhält. Durch die direkte Absaugung des Bestäubungsmaterials an den Austrittsöffnungen werden z. B. Schleppströmungen der Greifersysteme sowie Turbulenzen, die durch den Bedruckstoff selbst und/oder auch die zugeordneten Leiteinrichtungen erzeugt werden, reduziert. Die Absaugelemente der Absaugeinrichtung sind vorzugsweise formatabhängig (Formatlänge und Formatbreite) und/oder abhängig vom Druckbild (Farbbelegung) aktivierbar. Gleichzeitig wird durch die ausgewählt aktivierten Austrittsdüsen eine gleichmäßigere Bestäubung im Ergebnis erzielt, da der nicht abgesaugte Teil im Volumenstrom gezielt auf den Bedruckstoff auftrifft.Furthermore, the outlet nozzles are a plurality of movable suction elements of a suction device assigned through which the pollination material directly to the outlet openings the nozzles are selectively extractable controlled. The pollinated material extracted is in can be fed back to a circuit of the pollination device. A reprocessing the pollination material within the cycle is usually not necessary because the pollination material is sucked off directly at the outlet openings of the nozzles and thus does not get any noticeable contact with paint, paper dust or air humidity. By the direct suction of the pollination material at the outlet openings are such. B. Drag flows of the gripper systems as well as turbulence caused by the substrate itself and / or the associated control devices are generated, reduced. The Suction elements of the suction device are preferably format-dependent (format length and format width) and / or depending on the print image (color assignment) can be activated. At the same time, the selected activated outlet nozzles ensure a more uniform pollination achieved in the result, since the part not extracted in the volume flow is aimed specifically at the Substrate strikes.

Einer Mehrfarben-Offsetdruckmaschine ist ein Ausleger nachgeordnet. Mittels eines umlaufenden Fördersystemes 1 werden mit der Vorderkante im Greitverschluß gefaßte bogenförmige Bedruckstoffe 4 von Greifersystemen 2 in Förderrichtung 3 über eine Bogenbremse 5 einem Auslegerstapel 6 zugeführt und an Anschlägen abgelegt. Zur Unterstützung der Bogenablage auf den Auslegerstapel 6 ist oberhalb dessen in einem Feld eine Blaseinrichtung 8 angeordnet. Der Ausleger weist weiterhin Leiteinrichtungen 7 für die Bogenführung auf. Im Bogenaufgang des Auslegers ist eine Bestäubungseinrichtung 10 angeordnet, der in Förderrichtung 3 eine Trocknereinrichtung (nicht gezeigt) vorgeordnet ist. Die der Trocknereinrichtung benachbarte Leiteinrichtung 7 ist von einem Kühlmittel durchströmbar. A boom is arranged downstream of a multi-color offset printing machine. By means of a rotating Conveyor system 1 are arched with the leading edge in the slide closure Substrates 4 from gripper systems 2 in conveying direction 3 via a sheet brake 5 fed to a boom stack 6 and placed on stops. In support of Sheet deposit on the delivery stack 6 is a blowing device above it in a field 8 arranged. The boom also has guide devices 7 for the sheet guide on. A pollination device 10, which is arranged in Conveying direction 3 a dryer device (not shown) is arranged upstream. That of the dryer A coolant can flow through adjacent guide device 7.

Die Bestäubungseinrichtung 10 erstreckt sich über die maximale Formatbreite des zu bearbeitenden Bedruckstoffes und weist wenigstens eine über die Bedruckstoffbreite sich erstreckende, formatabhängig aktivierbare Reihe von Düsen 11 auf. Die Düsen 11 sind bevorzugt als Bohrungen und/oder Schlitze ausgebildet.
Die Beaufschlagung mit dem Bestäubungsmaterial, z.B. Puder, erfolgt mittels Druckluft und Puder als Gemisch. Alternativ kann jeder Düse 11 für den Austritt von Druckluft eine weitere Öffnung, z.B. als weitere Düse 11, für den Austritt von Puder benachbart zugeordnet sein.
Puder und Druckluft bilden einen Volumenstrom, der auf die Oberseite des Bedruckstoffes auftrifft. Die Düsen 11 für den Austritt von Druckluft in Kombination mit Puder bzw. als Puder-Druckluftgemisch sind, bezogen auf eine Förderebene 9 für den Bedruckstoff 4, in einem spitzen Winkel α, z. B. von 60°, in Förderrichtung 3 geneigt und bilden in der Betriebsart "Bestäuben" einen Volumenstrom in geneigter Strömungsrichtung 14 auf den Bedruckstoff aus.
Für den Sonderfall, daß der Winkel α = 0 ist, sind die Düsen 11 der Bestäubungseinrichtung 10 parallel zur Förderebene 9 angeordnet. Der Volumenstrom (Puder und Druckluft) tritt zuerst parallel zur Förderebene 9 aus den Düsen 11 aus und trifft unterstützt durch die Schwerkraft geneigt auf den Bedruckstoff auf. Die Absaugeinrichtung 13 bzw. die Absaugelemente sind wiederum den Düsen 11 an deren Austrittsöffnungen bewegbar zugeordnet.
The dusting device 10 extends over the maximum format width of the printing material to be processed and has at least one row of nozzles 11 that can be activated depending on the format and extends across the printing material width. The nozzles 11 are preferably designed as bores and / or slots.
The pollination material, eg powder, is applied by means of compressed air and powder as a mixture. Alternatively, a further opening, for example as a further nozzle 11, for the exit of powder can be associated with each nozzle 11 for the exit of compressed air.
Powder and compressed air form a volume flow that strikes the top of the substrate. The nozzles 11 for the discharge of compressed air in combination with powder or as a powder-compressed air mixture are, based on a conveying plane 9 for the printing material 4, at an acute angle α, z. B. of 60 °, inclined in the conveying direction 3 and form a volume flow in the inclined flow direction 14 on the substrate in the "dusting" mode.
For the special case that the angle α = 0, the nozzles 11 of the dusting device 10 are arranged parallel to the conveying plane 9. The volume flow (powder and compressed air) first emerges from the nozzles 11 parallel to the conveying plane 9 and, supported by gravity, strikes the printing material at an incline. The suction device 13 or the suction elements are in turn movably assigned to the nozzles 11 at their outlet openings.

Die Bestäubungseinrichtung 10 ist mit einer Einrichtung für die Versorgung mit Bestäubungsmaterial (Puder) und mit einer Druckluftversorgung gekoppelt.The pollination device 10 is provided with a device for the supply of pollination material (Powder) and coupled with a compressed air supply.

Durch den geneigten Volumenstrom wird der Bereich der Bedruckstoffvorderkante direkt hinter dem Greifersystem 2 besser bestäubt, da bedingt durch die geneigte Strömungsrichtung 14 dieser Bereich gezielt bestäubbar ist. Unmittelbar unterhalb der Düsen 11 ist eine Absaugeinrichtung 13 angeordnet, die durch mehrere Absaugelemente gebildet ist. Die Absaugeinrichtung 13 ist für die Absaugung von Bestäubungsmaterial direkt den Düsen 11 zugeordnet und ist mit einer Saugquelle gekoppelt, die mit der Versorgungseinrichtung für das Bestäubungsmaterial einen Kreislauf bildet. Due to the inclined volume flow, the area of the front edge of the substrate becomes direct better dusted behind the gripper system 2 because of the inclined flow direction 14 this area can be pollinated in a targeted manner. Immediately below the nozzle 11 is one Suction device 13 is arranged, which is formed by a plurality of suction elements. The suction device 13 is for the extraction of dusting material directly from the nozzles 11 assigned and is coupled to a suction source which is connected to the supply device for the pollination material forms a cycle.

Die Absaugeinrichtung 13 kann dabei im Ausleger fixiert sein und die zugeordnete Bestäubungseinrichtung 10 ist in einer Bewegungsrichtung 12 vorzugsweise linear, verschiebbar angeordnet (Fig. 2). In einer weiteren Ausbildung ist die Bestäubungseinrichtung 10 im Ausleger fixiert und die Absaugeinrichtung 13 ist verschiebbar oder verschwenkbar angeordnet (Fig. 3).
Die Absaugeinrichtung 13 (incl. Absaugelemente) und/oder die Bestäubungseinrichtung 10 sind ebenso derart ausführbar, daß zwischen beiden Einrichtungen 10,13 eine Relativbewegung möglich ist.
Dabei können auch einzelne oder mehrere Absaugelemente der Absaugeinrichtung 13 vorzugsweise formatabhängig und/oder abhängig vom Druckbild betätigbar, z.B. verschiebbar bzw. verschwenkbar, ausgebildet sein. Gemäß Fig. 3 ist eine Ausführung dargestellt, bei der die Absaugeinrichtung 13 schwenkbar den Düsen 11 der Bestäubungeinrichtung 10 zugeordnet ist.
The suction device 13 can be fixed in the boom and the associated dusting device 10 is preferably linearly displaceable in a direction of movement 12 (FIG. 2). In a further embodiment, the dusting device 10 is fixed in the boom and the suction device 13 is arranged to be displaceable or pivotable (FIG. 3).
The suction device 13 (including suction elements) and / or the dusting device 10 can also be implemented in such a way that a relative movement is possible between the two devices 10, 13.
In this case, one or more suction elements of the suction device 13 can also be designed to be operable, for example displaceable or pivotable, depending on the format and / or depending on the printed image. 3, an embodiment is shown in which the suction device 13 is pivotally assigned to the nozzles 11 of the dusting device 10.

Für die Absaugung von Bestäubungsmaterial ist den Düsen 11 die Absaugeinrichtung 13 bzw. ein Absaugelement unmittelbar zugeordnet. Weist die Bestäubungseinrichtung 10 paarweise angeordnete Düsen 11 für den separaten Austritt von Druckluft und Bestäubungsmaterial auf, sind die Absaugelemente der Absaugeinrichtung paarweise bewegbar. Damit ist der Volumenstrom von Bestäubungsmaterial und Luft an der, bzw. den Düsen 11 direkt absaugbar, wobei auch ein Teilvolumenstrom absaugbar ist.The suction device 13 is the suction device 13 for the extraction of dusting material or a suction element directly assigned. Instructs the pollinator 10 Nozzles 11 arranged in pairs for the separate discharge of compressed air and pollination material on, the suction elements of the suction device can be moved in pairs. The volume flow of dusting material and air at the nozzle 11 is thus directly extractable, whereby a partial volume flow can also be extracted.

Ein in einem gestellfesten Drehgelenk 15 gelagerter Schwinghebel 18 trägt an einem Ende die Absaugeinrichtung 13 , bzw. wenigstens ein Absaugelement, und am anderen Ende eine Rolle 17, die mit einer im Maschinentakt gesteuerten Kurvensteuerung 16 in Eingriff ist. Über die Kurvensteuerung 16 ist die Absaugeinrichtung 13 unterhalb der Düsen 11 in eine Strömungsrichtung 14 des Volumenstromes einschwenkbar. In einer weiteren Ausbildung ist der Bestäubungseinrichtung 10, speziell den Düsen 11, eine Absaugeinrichtung 13 als tangential und/oder axial bewegbare Schieber mit entsprechenden Öffnungen für die Absaugung von Bestäubungmaterial ausgebildet zugeordnet. Der Schieber ist mit einer Betätigungseinrichtung, z.B. einem Arbeitszylinder, gekoppelt. A rocker arm 18 mounted in a swivel joint 15 fixed to the frame carries at one end the suction device 13, or at least one suction element, and one at the other end Roller 17 which engages with a cam controller 16 controlled in the machine cycle.

In further training is the dusting device 10, especially the nozzles 11, a suction device 13 as Tangentially and / or axially movable slide with corresponding openings for suction associated with pollination material trained. The slide is with an actuator, e.g. a working cylinder.

Die Bewegbarkeit der Absaugeinrichtung 13 bzw. der Absaugelemente ist nicht auf das Ausführungsbeispiel beschränkt. Vielmehr kann die bewegbare Ausführung von Absaugeinrichtung 13 bzw. der Absaugelemente durch eine Anordnung an einer Koppel eines Gelenkgetriebes realisiert werden. Ebenso kann der Antrieb bzw. die Steuerung der Absaugeinrichtung 13 bzw. der Absaugelemente über eine separate Betätigungseinheit, z.B. Arbeitszylinder, Stellmotor, bewirkt werden.The mobility of the suction device 13 or the suction elements is not due to that Embodiment limited. Rather, the movable version of the suction device 13 or the suction elements by an arrangement on a coupling of an articulated gear will be realized. Likewise, the drive or the control of the suction device 13 or the suction elements via a separate actuation unit, e.g. Working cylinder, Actuator.

Die Wirkungsweise ist wie folgt:
Das umlaufende Fördersystem 1 transportiert mittels Greifersystemen 2 bogenförmige Bedruckstoffe 4 in Förderrichtung 3 auf einen Auslegerstapel zu. Im oberen Bereich des Bogenaufganges durchläuft das Greifersystem 2 mit dem Bedruckstoff4 die Bestäubungseinrichtung 10. Die Bestäubungseinrichtung 10 ist aktiviert und bestäubt in Förderrichtung 3 ständig den vorbeieilenden Bedruckstoff4 in Strömungsrichtung 14 in einem spitzen Winkel α von z.B. 60°, bezogen auf die Förderebene 9. Der Volumenstrom erreicht durch die Neigung der Düsen 11 im Winkel α auch den sonst durch das Greifersystem 2 verdeckten Bereich der Vorderkante des Bedruckstoffes 4.
The mode of action is as follows:
The rotating conveyor system 1 transports sheet-shaped printing materials 4 in the direction of conveyance 3 to a stack of delivery arms by means of gripper systems 2. In the upper area of the sheet emergence, the gripper system 2 with the printing material 4 runs through the pollinating device 10. The pollinating device 10 is activated and continuously pollinates in the conveying direction 3 the pasting printing material 4 in the flow direction 14 at an acute angle α of, for example, 60 °, based on the conveying plane 9 Due to the inclination of the nozzles at an angle α, the volume flow also reaches the area of the front edge of the printing material 4 which is otherwise covered by the gripper system 2.

Abhängig von der Formatbreite des Beduckstoffes 4 sind die über das Format sich erstrekkenden Düsen 11 einzeln oder Gruppenweise abschaltbar. Ist dies nicht der Fall, so können alternativ diesen Düsen 11 Absaugelemente der Absaugeinrichtung 13 ständig zugeordnet werden. Durch diese Anordnung ist das Bestäubungsmaterial direkt beim Austritt aus den ausgewählten Düsen 11 absaugbar.Depending on the format width of the printing material 4, those extending over the format are Nozzles 11 can be switched off individually or in groups. If this is not the case, you can alternatively, these nozzles 11 are constantly assigned suction elements of the suction device 13 become. With this arrangement, the pollination material is directly at the exit from the selected nozzles 11.

Das "überschüssige" Bestäubungsmaterial gelangt somit nicht in die Druckmaschine und kann diese nicht verunreinigen. Mittels eines Kreislaufes ist das überschüssige Bestäubungsmaterial wieder der Bestäubungseinrichtung 10 zuführbar. Die Bestäubungseinrichtung 10 ist unter Berücksichtigung der Maschinengeschwindigkeit im Dauerbetrieb betreibbar. D.h. ist die Bestäubungseinrichtung 10 aktiviert, so wird ständig aus den freigeschalteten Düsen 11 ein Volumenstrom erzeugt. Abhängig von der Formatlänge und /oder Formatbreite des Bedruckstoffes 4 und/oder vom jeweiligen Druckbild (Farbbelegung) wird die Absaugeinrichtung 13 gesteuert. D.h. in den Zwischenbereichen des Fördersystemes, bei denen die Bedruckstoffhinterkante des vorliegenden Greifersystems und das nachfolgende Greifersystem einen Freiraum bilden, werden die Absaugelemente der Absaugeinrichtung 13 unter die Düsen 11 geschwenkt und ein ausgewählter Teil oder der gesamte Volumenstrome abgesaugt.
Ebenso kann abhängig vom Druckbild die Absaugeinrichtung 13 in Kombination zum Format oder separat gesteuert werden. D.h. bei ständig aktivierter Bestäubungseinrichtung 10 trifft ein Volumenstrom aus Puder und Druckluft auf die Druckbild tragenden Stellen des transportierten Bedruckstoffes auf. Bei Stellen auf dem Bedruckstoff, die kein Druckbild aufweisen, wird die Absaugeinrichtung 13 (bzw. Absaugelemente) aktiviert und bei erneuter Ankunft von Druckbildern auf dem gleichen Bedruckstoff wird die Absaugeinrichtung 13 abgeschaltet und der Druckbilder aufweisende Bedruckstoff erneut bestäubt. Die Steuerung erfolgt von einem Leitstand aus.
Dadurch wird der Verbrauch von überschüssigem Bestäubungsmaterial reduziert.
The "excess" pollination material does not get into the printing press and cannot contaminate it. The excess pollination material can be fed back to the pollination device 10 by means of a circuit. The pollination device 10 can be operated in continuous operation, taking into account the machine speed. That is, if the pollination device 10 is activated, a volume flow is continuously generated from the activated nozzles 11. The suction device 13 is controlled depending on the format length and / or format width of the printing material 4 and / or on the respective print image (color assignment). In other words, in the intermediate areas of the conveyor system, in which the backing material of the present gripper system and the subsequent gripper system form a free space, the suction elements of the suction device 13 are pivoted under the nozzles 11 and a selected part or the entire volume flow is suctioned off.
Likewise, depending on the printed image, the suction device 13 can be controlled in combination with the format or separately. In other words, when the pollination device 10 is constantly activated, a volume flow of powder and compressed air impinges on the areas of the printed substrate that carry the printed image. In the case of spots on the printing material that have no printed image, the suction device 13 (or suction elements) is activated, and when printed images arrive on the same printing material, the suction device 13 is switched off and the printing material having the printed images is dusted again. Control is carried out from a control center.
This reduces the consumption of excess pollination material.
