Wird für einen Druckauftrag das wenigstens eine Bremselement nicht benötigt, so kann es ohne nennenswerten Montageaufwand, und zwar durch einfaches Ziehen der Antriebswelle 6, aus dem Aufnahmeschacht 10 entnommen werden. Die Mündung des Saugkanals 13 wird dann von einem die Antriebswelle 6 innerhalb des Aufnahmeschachtes10 umgreifenden Verschlusselementes 12 mit angeformten Bund 12.1 abgedeckt, am besten zu sehen in Fig.2.
Nachdem also das erwähnte Bremselement aus dem Aufnahmeschacht 10 entfernt ist, wird das Verschlusselement 12 in den Aufnahmeschacht eingesetzt und nachfolgend die Antriebswelle-6 wie ursprünglich positioniert. In einer Weiterbildung kann das Verschlusselement 13 in wenigstens einem der Begrenzungselemente 8,9 gelagert angeordnet sein und derart ausgebildet sein, dass der Aufnahmeschacht verschlossen ist oder frei liegend ist. Hierzu eignet sich beispielsweise ein bewegbarer Schieber oder eine Jalousie. Dabei kann der Unterdruck am Saugkanal 13, beispielsweise mittels manuell betätigbarer oder ansteuerbarer Ventileinrichtung, abgestellt sein.In the receiving shaft 10, depending on the sheet material to be printed 1, one or more associated with a pneumatic vacuum source brake elements and / or at least one arc support means in the form of at least one arranged on the support arm 7 Sporenrädchens 7.1 be included. The limiting element 9 is equipped with a suction channel 13, which is connected via a hose 14 to a vacuum source, not shown. If at least one brake element is integrated in the receiving shaft, the mouth of the suction channel 13 is in operative connection with the inlet of a suction channel contained in the brake element.
If the at least one brake element is not required for a print job, then it can be removed from the receiving shaft 10 without significant installation effort, specifically by simply pulling the drive shaft 6. The mouth of the suction channel 13 is then covered by a the drive shaft 6 within the receiving shaft 10 encompassing closure element 12 with integrally formed collar 12.1, best seen in Fig.2 ,
Thus, after the mentioned brake element is removed from the receiving shaft 10, the closure element 12 is inserted into the receiving shaft and subsequently the drive shaft-6 as originally positioned. In a further development, the closure element 13 may be arranged to be mounted in at least one of the limiting elements 8, 9 and to be configured such that the receiving shaft is closed or is lying freely. For this purpose, for example, a movable slide or a blind is suitable. In this case, the negative pressure at the suction channel 13, for example by means of manually operable or controllable valve device, be turned off.

Das Verschlusselement 12 ist gem. Fig.2 zwischen dem ersten Begrenzungselement 8 und dem zweiten Begrenzungselement 9 eingespannt. Die notwendige Spannkraft wird dabei von wenigstens einem zwischen dem Begrenzungselement 8 und der dem Begrenzungselement 8 zugewandten Stirnseite des Verschlusselementes 12 eingeordneten Federelement 11 aufgebracht.
Zusätzlich zu der in Fig.1 vorhandenen einen Querführung 16 für die Einrichtung 4 kann achsparallel zur Querführung 16 eine weitere Querführung 17 vorhanden sein, die zur stabilen Führung und Positionierung der Einrichtung 4 beiträgt. Eine auf die Querführung 16 wirkende Rändelschraube 18 sorgt dafür, dass die von den Querführungen 16,17 getragene und quer zur Transportrichtung 15 des Bogenmaterials 1 positionierbare Einrichtung 4 in einer geeigneten Position arretierbar ist.The closure element 12 is gem. Fig.2 clamped between the first limiting element 8 and the second limiting element 9. The necessary clamping force is applied by at least one between the limiting element 8 and the boundary element 8 facing end side of the closure element 12 arranged spring element 11.
In addition to the in Fig.1 existing a transverse guide 16 for the device 4 may be axially parallel to the transverse guide 16, a further transverse guide 17 is present be that contributes to the stable guidance and positioning of the device 4. A knurled screw 18 acting on the transverse guide 16 ensures that the device 4, which is supported by the transverse guides 16, 17 and can be positioned transversely to the transport direction 15 of the sheet material 1, can be locked in a suitable position.

In Fig.2 befindet sich, entsprechend Fig.1, der Tragarm 7 mit den Sporenrädchen 7.1,7.2 in Arbeitsposition.
Der Tragarm 7 ist hier in einer um die Mittenachse 6.1 der Antriebswelle 6 vedaufenden, jedoch nicht näher dargestellten Gleitführung aufgenommen. Vorteilhafterweise können der Tragarm 7 und die an dessen einen Ende angeordneten Sporenrädchen 7.1,7.2 dabei so strukturiert sein, dass dieser ohne zusätzliche Hilfsmittel sowohl in der Arbeitsposition als auch in der Parkposition sicher verharren kann.
Die Lagerung des wenigstens einen Sporenrädchens 7.1,7.2 an dem Tragarm 7 bedarf an dieser Stelle keiner näheren Ausführungen, weil diese dem Fachmann überlassen ist. Entscheidend ist lediglich, dass das Sporenrädchen 7.1,7.2 frei drehend an dem Tragarm 7 aufgenommen ist und bei Kontakt mit dem in Richtung 15 und in Richtung des Auslegerstapels bewegten Bogenmaterial 1 von dem Bogenmaterial in Drehung versetzt werden kann.In Fig.2 is, accordingly Fig.1 , the support arm 7 with the spur wheel 7.1.7.2 in working position.
The support arm 7 is received here in a about the center axis 6.1 of the drive shaft 6 vedaufenden, but not shown slide. Advantageously, the support arm 7 and arranged at one end spur wheels 7.1,7.2 can be structured so that it can remain safely without additional aids both in the working position and in the parking position.
The storage of at least one spur wheel 7.1,7.2 on the support arm 7 requires at this point no further details, because this is left to the expert. All that matters is that the spur wheel 7.1.7.2 is freely rotatably received on the support arm 7 and, upon contact with the sheet material 1 moving in the direction 15 and in the direction of the delivery stack, can be rotated by the sheet material.

In den Fig.3 und 4 sind für gleiche Teile der in den Fig.1 und 2 gezeigten Ausführungsbeispiele gleiche Bezugszeichen verwendet. Der Unterschied zwischen den Fig. 1,2 und den Fig. 3,4 besteht lediglich in der Positionierung des Tragarms 7 mit den Sporenrädchen 7.1,7.2.
In Fig. 3 und 4 befindet sich der Tragarm 7 mit den Sporenrädchen 7.1,7.2 in der Parkposition. In diesem Falle fungieren die Führungsflächen 8.1,9.1 der Begrenzungselementen 8,9 als Bogenstützen der Einrichtung 4, d. h., vor dem Erreichen des Auslegerstapels wird zumindest ein Endabschnitt des Bogenmaterials 1 durch die Führungsflächen 8.1,9.1 der Einrichtung 4 gestützt. Zur Vermeidung einer sich wiederholenden Beschreibung soll auf die Beschreibung der Fig.1 und 2 verwiesen werden.In the 3 and 4 are for equal parts in the Fig.1 and 2 shown embodiments, the same reference numerals. The difference between the Fig. 1.2 and the Fig. 3.4 consists only in the positioning of the support arm 7 with the spur wheels 7.1,7.2.
In 3 and 4 is the support arm 7 with the spur wheels 7.1,7.2 in the park position. In this case, the guide surfaces 8.1,9.1 of the limiting elements 8,9 act as arch supports of the device 4, ie, before reaching the delivery stack, at least one end portion of the sheet material 1 is supported by the guide surfaces 8.1,9.1 of the device 4. To avoid a repetitive description, reference is made to the description of Fig.1 and 2 to get expelled.

Vielmehr kann jeder Tragarm 7, bevorzugt mit getriebetechnischen Mitteln gekoppelt, zur Mittenachse 6.1 der Antriebswelle 6 auf einer Führungskurve mit einer vorgegebenen Bahn bewegt werden. Als getriebetechnische Mittel eigenen sich vorzugsweise Koppel- und/oder Kurvengetriebe. Je nach vorgegebener Bahn kann dabei die Führungskurve tangential oder gekrümmt zur Antriebswelle 6 verlaufend ausgebildet sein, um den jeweiligen Tragarm 7 mit wenigstens einem Sporenrädchen 7.1; 7.2 wahlweise in die Arbeits- oder Parkposition zu bewegen.The invention is not limited to the embodiment described by way of example. Rather, each support arm 7, preferably coupled with gear technical means to the center axis 6.1 of the drive shaft 6 are moved on a guide cam with a predetermined path. As a transmission means own preferably coupling and / or cam gear. Depending on the given path while the guide curve tangentially or curved to the drive shaft 6 may be formed running to the respective support arm 7 with at least one spur wheel 7.1; 7.2 to move optionally to the working or parking position.

Jeder Tragarm 7 kann in einfachster Ausbildung manuell in die Arbeits- oder Parkposition (und zurück) bewegt werden. In einer Weiterbildung kann jeder Tragarm 7 getriebetechnisch gekoppelt mit je einer Betätigungseinrichtung, beispielsweise einem eigenmotorisch antreibbaren Einzelantrieb oder einem pneumatisch betreibbaren Arbeitszylinder, verbunden sein. Bevorzugt sind die Betätigungseinrichtungen schaltungstechnisch mit einer Maschinensteuerung und vorzugsweise einem Leitstand gekoppelt.Each support arm 7 can be moved in the simplest training manually in the working or parking position (and back). In a further development, each support arm 7 can be coupled in terms of transmission technology with one actuating device, for example a single-drive individual drive or a pneumatically operable working cylinder. Preferably, the actuators are circuitry coupled with a machine control and preferably a control station.
