The controller produces or generates a stopper or an alarm depending on the determined position of the specimen.

Description

Die Erfindung betrifft einen Falzapparat einer Druckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a folding apparatus of a printing press according to the preamble of claim 1.

Falzapparate von Druckmaschinen dienen der Ausbildung von Falzen an bedruckten Bedruckstoffen, wobei bei aus dem Stand der Technik bekannten Falzapparaten ein bahnförmiger Bedruckstoff üblicherweise zuerst durch eine mindestens einen Falztrichter aufweisende erste Längsfalzeinheit geführt wird, um so am bahnförmigen sowie vorzugsweise noch nicht durchtrennten Bedruckstoff einen Längsfalz auszubilden. Ausgehend von der ersten Längsfalzeinheit wird der bahnförmige Bedruckstoff in Richtung auf eine Schneideinheit geführt, die zumindest einen Schneidmesserzylinder und einen mit dem Schneidmesserzylinder zusammenwirkenden Nutenzylinder umfasst. Im Bereich der Schneideinheit werden vom bahnförmigen Bedruckstoff Exemplare durch Querschneiden abgetrennt. Der Schneideinheit ist üblicherweise eine Querfalzeinheit nachgeordnet, die zumindest einen Falzmesserzylinder sowie einen Falzklappenzylinder umfasst. An der Scheideinheit abtrennte Exemplare werden mit Hilfe des Falzmesserzylinders in Richtung auf den Falzklappenzylinder bewegt. Die vom bahnförmigen Bedruckstoff abgetrennten Exemplare, welche vom Falzmesserzylinder in Richtung auf den Falzklappenzylinder bewegt werden, werden unter Ausbildung eines ersten Querfalzes vom Falzmesserzylinder an den Falzklappenzylinder übergeben. Weitere, zweite Querfalze sind zwischen dem Falzklappenzylinder und einem Greiferzylinder ausbildbar, der mit dem Falzklappenzylinder zusammenwirkt. Die so mit einem Längsfalz sowie mit mindestens einem Querfalz versehenen Exemplare gelangen ausgehend von der Querfalzeinheit in den Bereich einer zweiten Längsfalzeinheit, die üblicherweise mehrere Falztische umfasst. Im Bereich der Falztische werden an den bereits vorgefalzten Exemplaren zweite Längsfalze ausgebildet, die parallel zu dem in der ersten Längsfalzeinheit ausgebildeten Längsfalz verlaufen.Folding machines of printing presses serve for the formation of folds on printed substrates, wherein in the case of folding machines known from the prior art, a web-shaped printing stock is usually first passed through a first longitudinal folding unit having at least one former, so as to form a longitudinal fold on the web-shaped and preferably not yet severed printing substrate , Starting from the first longitudinal folding unit, the web-shaped printing material is guided in the direction of a cutting unit, which comprises at least one cutting blade cylinder and a groove cylinder cooperating with the cutting blade cylinder. In the area of the cutting unit, copies of the web-shaped substrate are cut off by cross-cutting. The cutting unit is usually followed by a Querfalzeinheit downstream, comprising at least one folding blade and a jaw cylinder. Copies separated at the separating unit are moved in the direction of the jaw cylinder with the aid of the folding blade cylinder. The separated from the web-shaped substrate copies, which are moved by the folding blade cylinder in the direction of the jaw cylinder, are passed to form a first transverse fold from the folding blade cylinder to the jaw cylinder. Further, second Querfalze can be formed between the jaw cylinder and a gripper cylinder, which cooperates with the jaw cylinder. The copies thus provided with a longitudinal fold and with at least one transverse fold reach, starting from the transverse folding unit, into the region of a second longitudinal folding unit, which usually comprises a plurality of folding tables. In the region of the folding tables, second longitudinal folds are formed on the already pre-folded copies which run parallel to the longitudinal fold formed in the first longitudinal folding unit.

An Stelle der ersten Längsfalzeinheit kann auch ein sogenannter Magazinaufbau vorhanden sein, wobei im Magazinaufbau keine Längsfalzung sondern eine Längstrennung des Bedruckstoffs erfolgt. Weiterhin sind auch Falzapparate bekannt, die über keine Querfalzeinheit und/oder keine zweite Längsfalzeinheit stromabwärts der Schneideinheit verfügen.Instead of the first longitudinal folding unit, a so-called magazine structure may also be present, wherein in the magazine structure no longitudinal folding but longitudinal separation of the printing material takes place. Furthermore, folders are also known which have no Querfalzeinheit and / or no second Längsfalzeinheit downstream of the cutting unit.

Zwischen der ersten Längsfalzeinheit bzw. dem Magazinaufbau und der Schneideinheit kann eine Querperforationseinheit und/oder eine Längsperforationseinheit angeordnet sein, um den im Bereich der ersten Längsfalzeinheit vorgefalzten oder den im Bereich des Magazinaufbaus in Längsrichtung durchtrennten Bedruckstoff zu perforieren. Die Perforationen unterstützen die Ausbildung von Querfalzen in der Querfalzeinheit und/oder die Ausbildung von Längsfalzen in der zweiten Längsfalzeinheit.A transverse perforation unit and / or a longitudinal perforation unit can be arranged between the first longitudinal folding unit or the magazine assembly and the cutting unit in order to perforate the substrate pre-folded in the region of the first longitudinal folding unit or cut longitudinally in the region of the magazine structure. The perforations assist in the formation of transverse folds in the transverse folding unit and / or the formation of longitudinal folds in the second longitudinal folding unit.

Für den ordnungsgemäßen Betrieb eines Falzapparates ist es erforderlich, den ordnungsgemäßen Transport von Exemplaren durch den Falzapparat zu überwachen, um dann, wenn kein ordnungsgemäßer Transport der Exemplare durch den Falzapparat festgestellt wird, einen Stopper auszulösen und so Beschädigungen des Falzapparats zu vermeiden. Bei aus der Praxis bekannten Falzapparaten erfolgt die sogenannte Stopperüberwachung dadurch, dass Fehlexemplare im Falzapparat gezählt werden. Insbesondere bei hohen Produktgeschwindigkeiten ist diese Stopperüberwachung jedoch nicht ausreichend, um zuverlässig einen Falzapparat vor Beschädigungen zu schützen. Es besteht daher ein Bedarf an einem Falzapparat einer Druckmaschine mit einer für hohe Produktionsgeschwindigkeiten geeigneten Stopperüberwachung.For the proper operation of a folder, it is necessary to monitor the proper transport of copies through the folder to then, if no proper transport of the copies is determined by the folder, trigger a stopper and thus to avoid damage to the folder. In known from practice folders, the so-called stopper monitoring takes place in that misprints are counted in the folder. However, especially at high product speeds, this stopper monitoring is not sufficient to reliably protect a folder from damage. There is therefore a need for a folding apparatus of a printing press with a stopper monitoring suitable for high production speeds.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen neuartigen Falzapparat einer Druckmaschine zu schaffen.On this basis, the present invention has the object to provide a novel folder of a printing press.

Diese Aufgabe wird durch einen Falzapparat gemäß Anspruch 1 gelöst. Erfindungsgemäß ist in Transportrichtung des Bedruckstoffs gesehen stromabwärts der Schneideinheit entlang der Transportstrecke der Exemplare durch den Falzapparat mindestens ein Sensor positioniert, der die Exemplare messtechnisch erfasst und ein Messsignal an eine Steuerungseinheit übermittelt, wobei die Steuerungseinheit auf Grundlage des von dem oder jedem Sensor bereitgestellten Messsignals die Lage der Exemplare im Falzapparat relativ zu einem Maschinenwinkel bestimmt, und wobei die Steuerungseinrichtung abhängig von der so ermittelten Lage der Exemplare und von frei konfigurierbaren Grenzwerten für die Lage der Exemplare einen Stopper und/oder eine Warnmeldung auslöst bzw. generiert.This object is achieved by a folding apparatus according to claim 1. According to the invention, at least one sensor is positioned downstream of the cutting unit along the transport path of the specimens by the folding apparatus, which metrologically records the specimens and transmits a measuring signal to a control unit, the control unit based on the measuring signal provided by the or each sensor Determines the position of the copies in the folder relative to a machine angle, and wherein the control device triggers or generates a stopper and / or a warning depending on the thus determined position of the copies and of freely configurable limits for the position of the copies.

Beim erfindungsgemäßen Falzapparat erfolgt die Stopperüberwachung dadurch, dass mit Hilfe mindestens eines Sensors die Lage von Exemplaren im Falzapparat erfasst wird und in Abhängigkeit von frei konfigurierbaren Grenzwerten für die Lage der Exemplare ein Stopper und/oder eine Warnmeldung ausgelöst bzw. generiert wird. Hierdurch kann eine Stopperschnellerkennung bereitgestellt werden, die auch bei hohen Produktionsgeschwindigkeiten eine zuverlässige Stopperüberwachung ermöglicht, um so selbst bei hohen Produktionsgeschwindigkeiten eine Beschädigung des Falzapparats sicher ausschließen zu können.In the folder according to the invention, the stopper monitoring takes place in that the position of copies in the folder is detected with the aid of at least one sensor and a stopper and / or a warning message is triggered or generated depending on freely configurable limit values for the position of the copies. In this way, a stopper quick detection can be provided, which allows reliable stopper monitoring even at high production speeds, so as to be able to reliably exclude damage to the folder even at high production speeds.

Der ersten Längsfalzeinheit 12 ist eine Schneideinheit 13 nachgeordnet, die dem Abtrennen von Exemplaren vom bahnförmigen Bedruckstoff durch Querschneiden dient. Die Schneideinheit 13 umfasst einen Schneidmesserzylinder 14 sowie einen mit dem Schneidmesserzylinder 14 zusammenwirkenden Nutenzylinder 15. Im Bereich der Schneideinheit 13 vom bahnförmigen Bedruckstoff abgetrennte Exemplare werden an einem Sammelzylinder 16 des Falzapparats 10 gesammelt und ausgehend vom Sammelzylinder 16 einer zweiten Längsfalzeinheit 17 zugeführt, im Bereich derer an den abgetrennten Exemplaren zweite Längsfalze ausbildbar sind, die parallel zu den in der ersten Längsfalzeinheit 12 ausgebildeten ersten Längsfalzen verlaufen. Im Ausführungsbeispiel der Fig. 1 ist zwischen der ersten Längsfalzeinheit 11 und der Schneideinheit 13 eine Längsperforationseinheit 18 angeordnet, die der Ausbildung von Längsperforationen am Bedruckstoff dient, wobei die Längsperforationen die Ausbildung der zweiten Längsfalze im Bereich der zweiten Längsfalzeinheit 17 unterstützen. Fig. 1 shows a possible embodiment of a folding apparatus 10 according to the invention of a printing press, wherein the in Fig. 1 has shown a folding former 11 comprehensive first longitudinal folding unit 12, which serves to form a first Längsfalzes on web-like, not yet severed substrate. The first longitudinal folding unit 12 is followed by a cutting unit 13, which serves for the separation of copies of the web-shaped substrate by cross-cutting. The cutting unit 13 comprises a cutting blade cylinder 14 and cooperating with the cutting blade cylinder 14 groove cylinder 15 in the cutting unit 13 separated from the web substrate copies are collected on a collecting cylinder 16 of the folder 10 and fed from the collecting cylinder 16 a second Längsfalzeinheit 17, in the area on the separated copies second longitudinal folds can be formed, which run parallel to the first longitudinal fold unit 12 formed in the first longitudinal folds. In the embodiment of Fig. 1 between the first longitudinal folding unit 11 and the cutting unit 13, a longitudinal perforation unit 18 is arranged which serves to form longitudinal perforations on the printing substrate, the longitudinal perforations supporting the formation of the second longitudinal folds in the region of the second longitudinal folding unit 17.

Zum Transport des Bedruckstoffs bzw. der Exemplare durch die Falzeinheit 10 dienen Zugwalzen 19. Mit Hilfe einer Beschleunigungseinheit 20 sind vom Bedruckstoff abgetrennte Exemplare auf die Umfangsgeschwindigkeit des Sammelzylinders 16 beschleunigbar.With the help of an acceleration unit 20 are separated from the substrate copies on the peripheral speed of the collecting cylinder 16 can be accelerated to transport the substrate or the copies by the folding unit 10.

Das in Fig. 1 dargestellte Ausführungsbeispiel eines Falzapparats 10 dient lediglich der Ausbildung von Längsfalzen am Bedruckstoff. Die Erfindung soll jedoch nicht auf diese konkrete Ausführungsform eines Falzapparats beschränkt sein, vielmehr kann die Erfindung auch an Falzapparaten Verwendung finden, die zusätzlich über mindestens eine Querfalzeinheit sowie gegebenenfalls eine Querperforationseinheit verfügen.This in Fig. 1 illustrated embodiment of a folding apparatus 10 is merely the formation of longitudinal folds on the substrate. However, the invention should not be limited to this specific embodiment of a folder, but the invention can also be used on folders, which additionally have at least one Querfalzeinheit and optionally a Querperforationseinheit.

Beim Falzapparat 10 der Fig. 1 ist stromabwärts der Schneideinheit 13 und stromaufwärts des Sammelzylinders 16 entlang der Transportstrecke von im Bereich der Schneideinheit 13 vom Bedruckstoff abgetrennten Exemplaren 21 ein Sensor 22 positioniert. Der Sensor 22 erfasst die Exemplare 21 messtechnisch und übermittelt ein Messsignal 23 an eine Steuerungseinheit 24 (siehe Fig. 2). Der Steuerungseinheit 24 wird als weitere Eingangsgröße ein Signal 25 eines Impulsgebers zugeführt, welches Informationen über den Maschinenwinkel der Druckmaschine und damit des Falzapparats 10 enthält.When folding apparatus 10 of Fig. 1 is a sensor 22 downstream of the cutting unit 13 and upstream of the collecting cylinder 16 along the transport path of in the region of the cutting unit 13 separated from the printing material 21 positioned. The sensor 22 detects the specimens 21 by measurement and transmits a measurement signal 23 to a control unit 24 (see Fig. 2 ). The control unit 24 is supplied as a further input signal, a signal 25 of a pulse generator, which contains information about the machine angle of the printing press and thus of the folder 10.

Die Steuerungseinheit 24 bestimmt auf Grundlage des vom Sensor 22 bereitgestellten Messsignals 23 sowie auf Basis des Signals 25 des Impulsgebers die Lage der Exemplare 21 im Falzapparat relativ zum Maschinenwinkel. Dies erfolgt vorzugsweise derart, dass der Sensor 22 eine Vorderkante der Exemplare 21 durch eine entsprechende Signalflanke im Messsignal 23 erfasst, wobei die Steuerungseinheit 24 überprüft, in welchem Winkelbereich des Maschinenwinkels diese Signalflanke und damit die Vorderkante der Exemplare 21 liegt.The control unit 24 determines the position of the copies 21 in the folder relative to the machine angle on the basis of the measurement signal 23 provided by the sensor 22 and on the basis of the signal 25 of the pulse generator. This is preferably done such that the sensor 22 detects a leading edge of the specimens 21 by a corresponding signal edge in the measurement signal 23, the control unit 24 checks in which angular range of the machine angle this signal edge and thus the leading edge of the specimens 21 is located.

Abhängig von der so ermittelten Lage der Exemplare 21 relativ zum Maschinenwinkel und von frei konfigurierbaren Grenzwerten für die Lage der Exemplare, die der Steuerungseinheit 24 als Signal 26 zuführbar sind, generiert die Steuerungseinheit 24 ein Ausgangssignal 27, um einen Stopper und/oder eine Warnmeldung auszulösen.Depending on the thus determined position of the copies 21 relative to the machine angle and of freely configurable limit values for the position of the copies, which can be supplied to the control unit 24 as a signal 26, the control unit 24 generates an output signal 27 to trigger a stopper and / or a warning message ,

Dann, wenn die auf die obige Art und Weise ermittelte Lage der Exemplare 21 im Falzapparat 10 innerhalb eines von einem ersten oberen Grenzwert und einem ersten unteren Grenzwert definierten ersten Wertebereichs für den Maschinenwinkel liegt, schließt die Steuerungseinheit 24 auf eine ordnungsgemäße Lage der Exemplare 21 im Falzapparat und löst dann weder einen Stopper noch eine Warnmeldung aus.Then, when the position of the pads 21 in the folder 10 determined in the above manner is within a first range of machine angle values defined by a first upper limit and a first lower limit, the control unit 24 concludes that the copies 21 are in proper position Folder and then triggers neither a stopper nor a warning message.

Dann hingegen, wenn die auf die obige Art und Weise ermittelte Lage der Exemplare 21 innerhalb eines von dem ersten oberen Grenzwert oder einen zweiten oberen Grenzwert definierten zweiten Wertebereichs für den Maschinenwinkel oder innerhalb eines von dem ersten unteren Grenzwert und einem zweiten unteren Grenzwert definierten dritten Wertebereichs für den Maschinenwinkel liegt, generiert die Steuerungseinheit 24 ein Ausgangssignal 27, mit welchem zwar eine Warnmeldung jedoch kein Stopper ausgelöst wird. Hierbei ist der zweite obere Grenzwert größer als der erste untere Grenzwert und der zweite untere Grenzwert ist kleiner als der erste untere Grenzwert.On the other hand, if the position of the specimens 21 determined in the above manner is within a second value range for the machine angle defined by the first upper limit or a second upper limit, or within a third range of values defined by the first lower limit and a second lower limit is for the machine angle, the control unit 24 generates an output signal 27, with which although a warning message but no stopper is triggered. Here, the second upper limit is greater than the first lower limit and the second lower limit is less than the first lower limit.

Dann, wenn die auf die obige Art und Weise ermittelte Lage der Exemplare weder innerhalb des ersten Wertebereichs noch innerhalb des zweiten und dritten Wertebereichs liegt, schließt die Steuerungseinheit 24 auf eine nicht ordnungsgemäße Lage der Exemplare 21 im Falzapparat und generiert ein Ausgangssignal 27, welches zumindest einen Stopper bzw. eine Stoppmeldung und vorzugsweise auch eine Warnmeldung auslöst.Then, if the position of the specimens determined in the above manner is neither within the first value range nor within the second and third value ranges, the control unit 24 concludes that the copies 21 are not in the correct position in the folder and generates an output signal 27 which is at least a stopper or a stop message and preferably also triggers a warning message.

In einem konkreten Ausführungsbeispiel soll davon ausgegangen werden, dass dann eine ordnungsgemäße Lage der Exemplare 21 im Falzapparat 10 gegeben ist, wenn der Sensor 22 die Vorderkanten derselben bei einem Maschinenwinkel von 40° detektiert. In diesem Fall kann der erste untere Grenzwert 35° und der erste obere Grenzwert 45° betragen, wobei dann, wenn die Steuerungseinheit 24 feststellt, dass die Vorderkanten der Exemplare 21 in dem durch diese Grenzwerte definierten ersten Wertebereich zwischen 35° und 45° liegen, dieselbe weder einen Stopper noch eine Warnmeldung auslöst. Der zweite obere Grenzwert kann in diesem Fall 50° und der zweite untere Grenzwert kann in diesem Fall 30° betragen, wobei dann, wenn die Steuerungseinheit 24 feststellt, dass die Lage der Vorderkanten der Exemplare innerhalb des zweiten Wertebereichs zwischen 45° und 50° oder innerhalb des dritten Wertebereichs zwischen 30° und 35° liegt, dieselbe eine Warnmeldung, jedoch keinen Stopper auslöst.In a concrete exemplary embodiment, it should be assumed that a correct position of the copies 21 in the folding apparatus 10 is then given if the sensor 22 detects the leading edges thereof at a machine angle of 40 °. In this case, the first lower limit may be 35 ° and the first upper limit may be 45 °, and if the control unit 24 determines that the leading edges of the specimens 21 are within the first range of values defined by these limits between 35 ° and 45 °, it does not trigger a stopper or a warning message. The second upper limit may in this case be 50 ° and the second lower limit may be 30 ° in this case, and if the control unit 24 determines that the position of the leading edges of the specimens within the second range of values is between 45 ° and 50 ° or within the third range of values between 30 ° and 35 °, the same a warning message, but does not trigger a stopper.

Dann hingegen, wenn die Steuerungseinheit 24 feststellt, dass die Lage der Vorderkanten der Exemplare in keinem dieser Wertebereiche liegt, löst die Steuerungseinheit 24 einen Stopper bzw. eine Stoppmeldung und gegebenenfalls eine Warnmeldung aus.On the other hand, if the control unit 24 determines that the position of the front edges of the specimens does not lie in any of these value ranges, the control unit 24 triggers a stop or a stop message and possibly a warning message.

Beim erfindungsgemäßen Falzapparat ist demnach die Lage der Exemplare 21, nämlich die Lage von Vorderkanten derselben, mit Hilfe mindestens eines Sensors 22 erfassbar, wobei der Sensor 22 einen entsprechenden Messwert 23 an die Steuerungseinheit 24 übermittelt, welche die Lage der Exemplare 21 im Falzapparat relativ zum Maschinenwinkel bestimmt und ermittelt, in welchem frei konfigurierbaren Wertebereich die so ermittelte Lage der Exemplare liegt. Abhängig hiervon kann ein Stopper bzw. eine Stoppmeldung und/oder eine Warnmeldung ausgelöst bzw. generiert werden.In the folder according to the invention, therefore, the position of the copies 21, namely the position of leading edges of the same, with the aid of at least one sensor 22 detected, the sensor 22 transmits a corresponding measured value 23 to the control unit 24, which the position of the copies 21 in the folder relative to Machine angle determines and determines in which freely configurable value range the thus determined position of the copies lies. Depending on this, a stopper or a stop message and / or a warning message can be triggered or generated.

Im Ausführungsbeispiel der Fig. 1 ist entlang des Transportwegs der Exemplare 21 stromabwärts der Schneideinheit 13 ausschließlich ein Sensor 22 positioniert. Im Unterschied hierzu ist es auch möglich, stromabwärts der Schneideinheit 13 entlang des Transportwegs der Exemplare 21 mehrere Sensoren 22 zu positionieren, um so in unterschiedlichen Bereichen der Transportstrecke des Falzapparats die Lage der Exemplare im Falzapparat zu überwachen.In the embodiment of Fig. 1 along the transport path of the copies 21 downstream of the cutting unit 13, only one sensor 22 is positioned. In contrast, it is also possible, downstream of the cutting unit 13 along the transport path of the copies 21 to position a plurality of sensors 22 so as to monitor the position of the copies in the folder in different areas of the transport path of the folder.

Im Sinne der hier vorliegenden Erfindung ist es möglich, dass die Steuerungseinheit 24 die auf die obige Art und Weise ermittelte Lage der Exemplare im Falzapparat auf eine Anzeigeeinrichtung visualisiert und hierzu ein weiteres Ausgangssignal 27 bereitstellt. So ist es z. B. möglich, auf einem Monitor schematisiert den Falzapparat mit seinen einzelnen Aggregaten darzustellen, und zwar zusammen mit der Position des oder jedes Sensors, der entlang der Transportstrecke der Exemplare durch den Falzapparat positioniert ist. Dann, wenn von dem jeweiligen Sensor eine ordnungsgemäße Lage der Exemplare im Falzapparat erkannt wird, können entsprechende Exemplare auf dem Monitor in einer ersten Farbe, z. B. in grün, visualisiert werden.For the purposes of the present invention, it is possible for the control unit 24 to visualize the position of the copies determined in the above manner in the folding apparatus on a display device and to provide a further output signal 27 for this purpose. So it is z. For example, it is possible to schematize on a monitor the folder with its individual aggregates, together with the position of the or each sensor positioned along the transport path of the copies by the folder. Then, if a correct position of the copies in the folder is detected by the respective sensor, corresponding copies on the monitor in a first color, z. B. in green, visualized.

Dann hingegen, wenn aufgrund der oben beschriebenen Lageermittlung der Steuerungseinheit 24 eine Warnmeldung generiert wird, können die Exemplare in einer zweiten Farbe, z. B. in gelb, visualisiert werden. Wird hingegen ein Stopper ausgelöst, so können die Exemplare auf dem Monitor in einer dritten Farbe, z. B. in rot, dargestellt werden, und zwar jeweils benachbart zum jeweiligen Sensor, der die für die jeweilige Lageermittlung notwendigen Messsignale bereitstellt. An jedem Messpunkt kann die Abweichung vom Sollwert angezeigt werden. Etwaige Abweichungen können wichtige Erkenntnisse über Unregelmäßigkeiten in der Maschine geben.On the other hand, if a warning message is generated on the basis of the above-described position determination of the control unit 24, the specimens can be printed in a second color, z. B. in yellow, visualized. If, on the other hand, a stopper is triggered, then the copies on the monitor can be displayed in a third color, eg. B. in red, in each case adjacent to the respective sensor, which provides the necessary for the respective position detection measurement signals. At each measuring point, the deviation from the setpoint can be displayed. Any deviations can give important information about irregularities in the machine.

Ebenso ist es beim erfindungsgemäßen Falzapparat möglich, dass die Steuerungseinheit 24 die auf die obige Art und Weise ermittelte Lage der Exemplare 21 in einer Speichereinheit speichert, um die so gespeicherten Messwerte für spätere Diagnosezwecke verwenden zu können.Likewise, it is possible with the folding device according to the invention that the control unit 24 stores the position of the copies 21 determined in the above manner in a memory unit in order to be able to use the measured values thus stored for later diagnosis purposes.

Ein Sollwert für die Lage der Exemplare 21 nach dem zweiten, von der zweiten Längsfalzeinheit 17 ausgeführten Längsfalz kann, um die Bewegungen des zweiten Längsfalzes zu kompensieren, auch von der Position des zweiten Längsfalzes abhängig sein. Wird der zweite Längsfalz z. B. relativ zum Falzwerk nach vorne verstellt, so können auch die Sollwerte für die Positionen der Exemplare 21 nach dem zweiten Längsfalz um den gleichen Betrag nach vorne verschoben werden. Die Grenzwerte für die Lage der Exemplare, mit welchen die messtechnisch ermittelte Lage der Exemplare verglichen wird, können demnach hiervon abhängig veränderbar sein.A setpoint for the position of the copies 21 after the second longitudinal fold executed by the second longitudinal folding unit 17 may also be dependent on the position of the second longitudinal fold in order to compensate for the movements of the second longitudinal fold. If the second longitudinal fold z. B. moved relative to the folding unit to the front, then the setpoints for the positions of the copies 21 can be moved to the second longitudinal fold by the same amount forward. The limit values for the position of the specimens, with which the metrologically determined position of the specimens is compared, can therefore be changed depending on this.
