The advantages that can be achieved with the invention are in particular that the substrates are printed on both sides. Further advantages can be seen from the explanations below.

In addition, the solution described can be used in a hybrid machine arrangement that processes sheet-shaped substrates, preferably in a hybrid printing machine that has the high productivity of a conventional, e.g. B. in an offset printing process or in a flexographic printing process or in a screen printing process printing device or a coating device, in particular a varnishing unit variable in combination with at least one flexibly each variable print images printing, z. B. uses non-impact printing device designed as an inkjet printer, both the conventional printing device or the coating device and the non-impact printing device are used in an ongoing production inline, each at the optimal working speed for them. Such a hybrid machine arrangement is particularly useful for the production of packaging materials, e.g. B. of sheets for the production of folding boxes is very advantageous because the strengths of each of the printing devices are used, which leads to a flexible and economical production of the packaging material. Thus, in particular, arch-shaped substrates of rigid design can advantageously be printed in a non-impact printing device in a flat state and in a horizontal position. The length of a linear transport device can be adapted to a different number of printing units or printing stations (color separations) and (intermediate) dryer configurations z.

On the other hand, a transport of arch-shaped substrates by means of rotating bodies, in particular cylinders and gripper bars or gripper carriages, each with a transfer of the arch-shaped substrates in the gripper connection to a subsequent processing station, as is known from sheet-fed offset printing machines, ensures the highest possible register accuracy.

The suction drum 32 takes an aligned sheet in particular by clocked suction air, that is, the suction air is z. B. in certain, preferably dependent on the transport speed and / or position of the sheet angular positions of the suction drum 32 quickly switched on and off again by the control unit. One on the transport level 29 to the direction of transport T Right-angled alignment of the front edge of the sheet in question is preferably achieved by pushing this edge against the at least one stop 34 the suction drum 32 achieved. Optional is e.g. B. also provided in the transfer device at least one side stop against which a sheet to be aligned with a parallel to its transport direction T running edge is encountered.

One preferably the first sensor 33 in transport direction T the sheet upstream of the second sensor 36 , which is preferably also connected to the control unit, detects z. B. the front edge and possibly also the number of the first conveyor belt 17th to the second conveyor belt 27 transported bow. The second sensor 36 preferably detects one in the transport direction T the sheet leading edge of the respective Sheets and is primarily used for sheet arrival control. The second sensor 36 is z. B. designed as an optical sensor, in particular as a reflex scanner or as a light scanner. In cooperation with the suction drum 32 is z. B. at least one in the direction of the effective area of the non-impact printing device 06 , ie in the direction of the second conveyor belt 27 , preferably linearly, in particular longitudinally to the transport path of the sheets extending guide element 37 provided, the relevant guide element 37 with the outer surface of the suction drum 32 forms a gusset in which the sheets from the first conveyor belt 17th to be introduced in the future. In the area of the first conveyor belt 17th and possibly also in the area of the second conveyor belt 27 are each z. B. one or more preferably each z. B. controllable by the control unit suction chambers 26th intended. The suction chambers 26th may be part of the transport facility 22nd . Including at least one suction chamber 26th of the first conveyor belt 17th In a preferred embodiment, the lateral alignment of the sheet takes place by axially displacing the suction drum 32 in particular after aligning the sheet in question on the at least one stop 34 and switching off the suction air in the transport direction T of the sheet in question last suction chamber 26th . This lateral alignment of the sheet becomes the rotational movement of the suction drum 32 superimposed in time. So that of the suction drum rests 32 to the next processing station 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheets to be transferred in this transfer device at no time. The suction drum 32 accordingly aligns the sheets in each case at least in their axial register and / or in their circumferential register in register relative to a processing position of the suction drum 32 subsequent processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th the end.

In the case of a machine arrangement with several processing stations for processing sheets, with in the transport direction T the arch several processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th these sheets are arranged one after the other for inline processing, at least one of these processing stations 06 as a non-impact printing device 06 is formed is the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th z.

The suction drum arranged in particular in the transfer device 32 is z. B. also used by the offset printing device 04 to the non-impact printing facility 06 to adapt the sheets to be transferred in their respective transport speed. Because those in the non-impact printing facility 06 applicable second transport speed is generally lower than that in the offset printing device 04 applicable first transport speed, brakes the suction drum 32 each one after the other at the first transport speed from the offset printing device 04 supplied sheet in each case by a push from the front edge of the at least one stop 34 first of all, aligns the sheet that has been sucked in, if necessary, that is, in the case of a corresponding position signal from the first sensor indicating a need for correction 33 at least laterally by an axial movement of the suction drum holding the sheet in question 32 and then accelerates or decelerates the gripped sheet by rotating this suction drum 32 on those in the non-impact printing facility 06 required second transport speed, the sheet in question z.

The suction drum 32 therefore rotates z. B. preferably non-uniform in each of their revolutions. One for regulating the rotation position of the suction drum 32 necessary position information from the front edge of the sheet provides a z. B. on a sprocket 24 arranged rotary encoder 47 or alternatively a rotary encoder of the offset printing device 04 , especially the printing press.

• Verfahren zum Betrieb einer mehrere Bogen einer Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 sequentiell zuführenden Transportvorrichtung, bei dem zum Bearbeiten durch dieselbe Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 Bogen unterschiedlicher sich jeweils in Transportrichtung T dieser Bogen erstreckender Länge verwendet werden, wobei die der Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nacheinander zuzuführenden Bogen von der Transportvorrichtung jeweils in einem Abstand transportiert werden, wobei die Transportvorrichtung den zu transportierenden Bogen jeweils eine Transportgeschwindigkeit aufprägt, wobei der zwischen unmittelbar aufeinander folgenden Bogen bestehende Abstand für Bogen verschiedener sich jeweils in Transportrichtung T dieser Bogen erstreckender Länge durch eine Veränderung der von der Transportvorrichtung den betreffenden Bogen aufzuprägenden Transportgeschwindigkeit konstant gehalten wird, wobei die Transportgeschwindigkeit des in Transportrichtung T nachfolgenden Bogens im Verhältnis zu der Transportgeschwindigkeit des unmittelbar vorausgehenden Bogens verändert wird. Dabei werden die der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nacheinander zuzuführenden Bogen zum Erreichen und/oder zum Beibehalten einer von der Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 zu erbringenden hohen Produktivität von der Transportvorrichtung jeweils vorzugsweise in einem minimalen, aber i. d. R. von Null verschiedenen Abstand transportiert. Der Abstand zwischen in Transportrichtung T aufeinanderfolgenden Bogen, d. h. zwischen der sich quer zur Transportrichtung T erstreckenden hinteren Kante des vorhergehenden Bogens und der sich quer zur Transportrichtung T erstreckenden Vorderkante des unmittelbar nachfolgenden Bogens, liegt z. B. im Bereich zwischen 0,5 mm und 50 mm, vorzugsweise bei weniger als 10 mm. Wenn ein Bogen kürzerer Länge in der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nach einem Bogen größerer Länge zu bearbeiten ist, wird der Bogen kürzerer Länge von der Transportvorrichtung durch eine Erhöhung seiner Transportgeschwindigkeit beschleunigt. Umgekehrt wird ein Bogen größerer Länge von der Transportvorrichtung durch eine Verringerung seiner Transportgeschwindigkeit verlangsamt, wenn der Bogen größerer Länge in der betreffenden Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 nach einem Bogen kürzerer Länge zu bearbeiten ist. Als Bearbeitungsstation 02; 03; 04; 06; 07; 08; 09; 11; 12 wird vorzugsweise eine Non-Impact-Druckeinrichtung 06 verwendet, deren Produktivität i. d. R. dann am größten ist, wenn ihr die von ihr zu bedruckenden Bogen ungeachtet ihres jeweiligen Formats in einem konstanten minimalen Abstand aufeinanderfolgend zugeführt werden. Wenn in der betreffenden Maschinenanordnung der Non-Impact-Druckeinrichtung 06 eine z.

Wenn diese Bogen ungeachtet ihres jeweiligen Formats zusätzlich noch jeweils in einem konstanten Abstand zueinander der Non-Impact-Druckeinrichtung 06 zugeführt werden sollen, werden Bogen größerer Länge weniger verlangsamt als kürzere Bogen, jedoch wird in jedem Fall eine Verringerung ihrer jeweiligen Transportgeschwindigkeit erforderlich sein, weil die Verarbeitungsgeschwindigkeit der Non-Impact-Druckeinrichtung 06 i. d. R. geringer ist als die Produktionsgeschwindigkeit der Offset-Druckeinrichtung 04.

As already mentioned, it is provided with the previously described machine arrangements, each of several processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th for processing sheets and for transporting these sheets have at least one transport device for processing sheets of different formats, ie of different lengths and / or widths. Therefore, the generally rectangular arches differ e.g. B. in their respective length, this length in each case in the direction of transport T this arch extends. In order to use one in particular as a non-impact printing device 06 trained processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th , the sheets are fed sequentially, the productivity of the respective machine arrangement with comparatively shorter sheets, ie with sheets of smaller format compared to otherwise larger-format sheets processed in this machine arrangement, a method with the following process steps is proposed:

• Method for operating a plurality of sheets in a processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sequentially feeding transport device, in which for processing by the same processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th Bow different each in the transport direction T this arc of extending length can be used, with that of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheets to be fed one after the other are transported by the transport device at a distance, the transport device imposing a transport speed on the sheets to be transported, the spacing between sheets immediately following one another for sheets different in each case in the transport direction T this sheet of extending length is kept constant by changing the transport speed to be impressed on the relevant sheet by the transport device, the transport speed of the in the transport direction T subsequent sheet is changed in relation to the transport speed of the immediately preceding sheet. In doing so, those of the relevant processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheets to be fed one after the other for reaching and / or maintaining one of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th The high productivity to be achieved is preferably transported by the transport device at a minimum, but generally non-zero distance. The distance between in the transport direction T successive sheets, ie between which are transverse to the transport direction T extending rear edge of the previous sheet and the transverse to the transport direction T extending leading edge of the immediately following sheet, z. B. in the range between 0.5 mm and 50 mm, preferably less than 10 mm. If an arc of shorter length is in the relevant processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th is to be processed after a sheet of greater length, the sheet of shorter length is accelerated by the transport device by increasing its transport speed. Conversely, a sheet of greater length is slowed down by the transport device by reducing its transport speed when the sheet of greater length is in the relevant processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th is to be machined after an arc of shorter length. As a processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th is preferably a non-impact printing device 06 is used, the productivity of which is usually greatest when the sheets to be printed by it are fed one after the other at a constant minimum distance, regardless of their respective format. If in the relevant machine arrangement of the non-impact printing device 06 a z. B. as an offset printing device 04 trained processing station 04 is upstream, are in the offset printing device 04 printed sheets regardless of their respective format with the one production speed of this offset printing device 04 corresponding transport speed of the transport device supplied, this sheet of the offset printing device 04 predetermined transport speed during its transport with the transport device to that of a processing speed of the non-impact printing device 06 appropriate transport speed is to be adjusted. If these sheets, regardless of their respective format, are additionally each at a constant distance from one another in the non-impact printing device 06 are to be fed, sheets of greater length are slowed down less than shorter sheets, but in any case a reduction in their respective transport speed will be necessary because of the processing speed of the non-impact printing device 06 is usually lower than the production speed of the offset printing device 04 .

The respective sheet is preferably frictionally z. B. held by suction air. The transport speed of the respective sheet is preferably determined by suction rings which act on it 76 a suction drum 32 or by at least one endlessly rotating suction belt 52 ; 78 imprinted. In the preferred embodiment, the transport speed to be imprinted on the sheet in question is set by a preferably electronic control unit. B. i. V. m. The rotational position control of the suction drum 32 has been described or e.g. B. i. V. m. A control device to be explained in more detail below and connected to this control device z. B. optical sensors 33 ; 36 will be described.

If with the machine arrangements described above, each of the several Processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th have at least two transport devices for the processing of sheets and for the transport of these sheets, flexible sheets are transported and processed, ie sheets of low flexural rigidity, especially thin sheets that cannot transfer any shear forces, so that thrust forces acting on such a sheet lay this sheet in waves , then it is difficult to get such sheets of the relevant processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th in one for this processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th to be supplied to the intended target position.

There is therefore a method for the sequential supply of a plurality of sheets to a processing station which processes these sheets in each case 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th proposed in which one of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th in transport direction T the sheet upstream first transport device the sheet of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th feeds each at a first transport speed in a pushing movement, the first transport device to the respective one of the processing stations 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th holding the feeding sheet during the pushing movement with at least one holding element, the relevant being the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th fed sheets from one of these processing stations 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th assigned second transport device is gripped and transported in the gripped state at a second transport speed, the first transport speed of the first transport device being lower than the second transport speed of the second transport device, the relevant holding element of the first transport device being the relevant one of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th only then releases the feeding sheet after the second transport device has reached the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th has taken the fed sheet and started transporting this sheet. As a processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th is preferably a non-impact printing device 06 used. In the first transport device and / or in the second transport device, the sheets are each in particular in the same transport plane 29 transported. As the first transport device z. B. a first, in particular endlessly circulating conveyor belt 17th and / or a second, in particular endlessly circulating, conveyor belt as the second transport device 27 used, these conveyor belts 17th ; 27 z. B. are each designed as a suction belt. In an alternative embodiment of the holding elements, these are each designed as a suction ring 76 a suction drum 32 educated. On the respective of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th The sheet to be fed is exerted a holding force by the holding element of the first transport device in question, this holding force being at least briefly greater than a tensile force exerted by the second transport device simultaneously acting on this sheet. The first transport device holds the respective one of the processing stations 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th feeding sheet with the at least one holding element each preferably by a force fit, for. B. by suction air. The proposed method becomes that of the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheet to be fed is subjected to a tensile stress and thereby tightened despite the pushing movement carried out by the first transport device. The sheets are preferably each after a check of their respective actual position in the transport plane 29 and in the event that the actual position deviates from one for the sheet in question in the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th The intended target position is transferred to the second transport device after a position correction has been carried out in the intended target position.

12th shows in an enlarged section from 10 handing over the sheets at the feed table 18th , especially from the third conveyor belt 28 in the area of action of the intermediate dryer 07 or dryer 09 to the area of action of the mechanical further processing device 11 . The feed table 18th shows z. B. at least a fourth conveyor belt 38 on, which is preferably at an acute angle φ to the preferably horizontal transport level 29 is arranged inclined. Also in connection with the fourth conveyor belt 38 is z. B. a third sensor 39 provided, each of a position signal from the with the fourth conveyor belt 38 The transported sheet is generated and sent to the control unit. It can e.g. B. be provided that one of the mechanical processing device 11 sheet to be fed in by the second oscillating gripper 19th and the second transfer drum 31 is brought from the second transport speed to the third transport speed, which means that the sheet in question in particular by the rotation of the second transfer drum controlled by the control unit 31 is accelerated. Also in the area of the fourth conveyor belt 38 are z. B. one or more preferably controllable suction chambers 42 intended. In a preferred embodiment, the sheet to the mechanical further processing device is located at the transfer device 11 an undercutting of these arches takes place. One is from the fourth conveyor belt 38 transported sheet is lifted in its rear area by means of clocked blown air and from the fourth conveyor belt 38 in connection with the suction chamber 42 delayed. A follow-up sheet is then made by the faster running front belt conveyor 48 dragged under the previous arch.

Preferably at the transfer device of the sheet to the mechanical further processing device 11 is accordingly a method for arranging sheets in a shingled position in a between a first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th and one in the transport direction T the sheet of the first processing station following the second processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th arranged transfer device executed, in which the sheets to be shingled from the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th in one transport level 29 are transported individually lying one after the other to the transfer device, one in each case in the transport direction T rear edge of the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th coming sheet exclusively by blown air relative to the transport plane 29 lifted and a subsequent sheet pushed under the rear edge of the previous sheet. The blown air acts with at least 50% of its intensity, preferably in the direction of one in the transport plane 29 standing normals against gravity. Advantageously, it is provided that further blown air against the transport direction T the arc essentially tangential under one with the transport plane 29 formed acute angle in the range of z. B. 0 ° to 45 ° from above, ie on that of the transport plane 29 facing away surface of the sheet is blown onto the sheet to be transported to the transfer device. The direction of transport occurs T the sheet opposite directed further blown air from one with the transport level 29 the arc has a converging acute angle in the range of e.g. B. 0 ° to 45 ° forming guide surface, in particular nozzles for the exit of the blown air are arranged in the guide surface. The one in the direction of the transport plane 29 Blown air acting against gravity is preferably clocked by the control unit. The one from the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th to the subsequent second processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th to be transported sheet is in each case by means of preferably in the transport direction T front half of the sheet acting suction air in the transport level 29 held. This is the one from the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th to the subsequent second processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheet to be transported in the transport level 29 holding suction air preferably clocked by the control unit. In the preferred embodiment, the control unit makes an orthogonal to the transport direction T the arc directed width of action in the direction of the transport plane 29 Blown air acting against gravity and / or an effective range of the direction of transport T the sheet counter-directed further blown air and / or an effective range for the from the first processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th to the subsequent second processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th sheet to be transported in the transport level 29 holding suction air depending on an orthogonal to the transport direction T the arc directional width of the arc set.

Each substrate is transported individually 51 , in particular sheets, are by means of a in the transport direction T the suction drum 32 upstream suction belt 78 first of all the suction drum 32 and from the suction drum 32 to another conveyor belt 27 headed, this conveyor belt 27 the substrate in question 51 especially a non-impact printing device 06 feeds. This is done by the suction drum 32 Substrate held in a force-fit manner by means of suction air 51 from this suction drum alone 32 each in the transport level 29 both in the transport direction T as well as across it and around one on the transport level 29 lying fulcrum with respect to the non-impact printing device 06 for the substrate in question 51 intended target position aligned. To this end, the suction drum 32 a first drive 91 for their circumferential movement and a second drive 92 for their axial movement and a third drive 93 for one by one perpendicular to the transport plane 29 standing axis of rotation 94 executed or at least executable pivoting movement of the axis of rotation 96 the suction drum 32 on, these three drives 91 ; 92 ; 93 each e.g. B. are designed as a preferably electric servomotor.

B. on one in the middle of the machine M. arranged swivel joint 98 is rotatably arranged, wherein the swivel joint 98 with a second frame 99 connected is. The one around the perpendicular to the transport plane 29 standing axis of rotation 94 executed rotary movement or swivel movement of the axis of rotation 96 the suction drum 32 takes place by means of the third drive 93 which, when operated, is away from the center of the machine M. on the first rack 97 attacks and in this way a diagonal alignment of the suction drum 32 held substrate 51 causes. That the first frame 97 load-bearing second frame 99 is in turn in or on a third frame 101 arranged, the second frame 99 in or on the third rack 101 when the second drive is actuated 92 across the direction of transport T of the substrate in question 51 is movable, in particular displaceable. There is also the second frame 99 in or on the third rack 101 in a z.

Another method of operating an apparatus for transporting sheet-shaped substrates 51 also uses a substrate in question 51 in its transport level 29 conveying transport element, wherein the transport element is the substrate in question 51 one of the transport element in the transport direction T of the substrate in question 51 downstream processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th in register, this processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th z. B. as a non-impact printing device 06 is trained. A suction drum is preferably used as the transport element 32 with several suction rings arranged axially next to one another, each designed as a holding element 76 or an arrangement of several in each case along the direction of transport T of the substrate in question 51 circumferential, transverse to the transport direction T of the substrate in question 51 suction belts arranged next to one another 52 ; 78 used. The transport element for transporting the substrate in question 51 therefore always uses several at right angles to its transport direction T holding elements arranged at a distance from one another, the substrate in question 51 of at least two of these holding elements each up to one on the transport level 29 related output position is held positively in each case. The respective output positions are all of the substrate in question 51 frictionally holding retaining elements on the same straight line 103 . The transport element creates a diagonal register of the substrate in question 51 set. The diagonal register of the substrate in question 51 is done by setting an angle of rotation β this straight line 103 around one perpendicular to the transport plane 29 standing axis of rotation 94 set, the angle of rotation β this straight line 103 according to the diagonal register to be set for the substrate concerned 51 by actuation of a single one on all of the substrate in question, triggered by a control unit 51 frictionally holding holding elements simultaneously acting mechanical coupling element is adjusted, whereby the respective output position of at least one of the holding elements frictionally holding the substrate in question is changed by the mechanical coupling element acting on the holding element in question. The the substrate in question 51 frictionally holding retaining elements shape the substrate in question 51 each has a transport speed that differs from holding element to holding element, with that of the respective holding element being the relevant substrate 51 impressed transport speed is dependent on the output position set for the respective holding element. As a mechanical coupling element z. B. used a linear gear member with rocker arms and / or with gear coupling gears, all the substrate in question 51 frictionally holding retaining elements are each assigned either a rocker arm or a gear coupling mechanism.

The proposed method for operating a device for transporting sheet-shaped substrates has the advantage that the relevant transport element is not positioned at an angle to set the diagonal register in the transport device. B. already set side register and / or axial register of the substrate in question cannot be negatively influenced by the setting of the diagonal register. Rather, between the holding elements of the transport element involved in setting the diagonal register, actuation of a single actuator sets a speed difference depending on the respective position of the respective holding element, whereby the relevant substrate is aligned according to the desired diagonal register. The use of only a single actuator for setting the diagonal register has the advantage that coordination between different drives acting on one of the holding elements or their adaptation to one another is not required, which eliminates a source of error and enables very precise setting of the diagonal register .

In a preferred embodiment of this method, the processing station is controlled by means of a control device connected to the control unit 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th substrate to be fed in register 51 before it reaches the transport element, its actual position in its transport plane 29 determined and with one for the substrate in question 51 in the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th provided target position compared, in the case of a deviation of the actual position from the target position, the control unit a drive that adjusts the mechanical coupling element 93 so that controls the substrate in question 51 with reaching the respective output positions of all holding elements holding the substrate in question in a force-fit manner in the processing station 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12th assumes intended target position with regard to the diagonal register.

Furthermore, the holding elements at a distance aS22 arranged. The respective planes of rotation of all the substrate in question 51 frictionally holding retaining elements are each parallel to one another and each along the direction of transport T of the substrate in question 51 arranged. The substrate in question 51 is transported by at least two of these holding elements each up to one on the transport level 29 related output position each held non-positively, the respective output positions of all the substrate in question 51 frictionally holding retaining elements on the same straight line 103 are located.

To the diagonal register of the substrate in question 51 adjust and thereby the substrate in question 51 To bring the relevant substrate from its actual position into its desired position, at least with regard to its angular position 51 by an angle of rotation β around one perpendicular to the transport plane 29 standing axis of rotation 94 rotated, which is done by making the straight line 103 around this angle of rotation β is rotated, which in turn takes place in that the respective output position of at least one of the substrate 51 frictionally holding holding elements is changed by the mechanical coupling element acting on the holding element in question. The angle of rotation β is usually in the range of only a few degrees, e.g. B. between greater than zero and less than 30 °, in particular less than 10 °.
