Description

Die Erfindung betrifft eine Einrichtung zum automatischen Steuern des Arbeitsabstandes der Falzklappen eines Falzklappenzylinders.The invention relates to a device for automatically controlling the working distance of the jaws of a jaw cylinder.

Bei dem Einrichten einer Rotationsdruckmaschine ist es notwendig, daß der Arbeitsabstand der Falzklappen im Falzapparat auf die Produktstärke der zu verarbeitenden Papierstränge eingestellt wird.When setting up a rotary printing press, it is necessary that the working distance of the folding jaws in the folder is adjusted to the product thickness of the paper strands to be processed.

Es ist in der Praxis tägliche Routine, daß z.B. im Zeitungsdruck Papierbahnen verschiedener Bahnstärken bei laufender Druckmaschine aneinandergeklebt und weiterverarbeitet werden. Hierbei ist es nicht ungewöhnlich, wenn dünnes Papier von 28 g/m² an dickes Papier von 48 g/m² angeklebt wird.It is a daily routine in practice that e.g. In newspaper printing, paper webs of different web thicknesses are glued to one another and further processed while the printing machine is running. It is not uncommon for thin paper of 28 g / m² to be glued to thick paper of 48 g / m².

Um auch den Falzapparat auf die neue Produktstärke während des Maschinenlaufes einstellen zu können ist es durch die DE-A-25 37 920 bekannt, einen in einer axialen Bohrung in der Falzklappenzylinderachse gelagertes kegelförmiges Gleitstück mittels eines Handrades mit Stellspindel axial zu verschieben.In order to also be able to adjust the folder to the new product strength while the machine is running, it is known from DE-A-25 37 920 to axially move a conical sliding piece mounted in an axial bore in the jaw cylinder axis by means of a handwheel with adjusting spindle.

Auf der schrägen Oberfläche des Gleitstückes greifen je Falzklappenpaar radial ausgerichtete Gleitstößel an. Die Gleitstößel wirken mit ihrem radial nach außen gerichteten Ende auf einen verstellbaren Falzklappenmechanismus.On the sloping surface of the slider, each pair of jaws engages radially aligned slide rams. With their radially outward end, the slide rams act on an adjustable jaw mechanism.

Es ist bei der durch die DE-A-25 37 920 gezeigten Vorrichtung von Nachteil, daß das die Falzklappenverstellung einleitende Gleitstück bei seiner axialen Stellbewegung in der Zylinderachsenbohrung verklemmen kann. Insbesondere jedoch ist nur eine manuelle Verstellung der Falzklappen vorgesehen.It is disadvantageous in the device shown by DE-A-25 37 920 that the sliding piece initiating the jaw adjustment can jam in the axial axis movement in the cylinder axis bore. In particular, however, only manual adjustment of the jaws is provided.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zu schaffen, die es ermöglicht, daß ein Falzklappenarbeitsabstand in Abhängigkeit von einer Papierbahndicke selbständig eingestellt werden kann.The invention has for its object to provide a device that enables a folding jaw working distance can be set independently depending on a paper web thickness.

Die Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.The object is achieved by the features of the characterizing part of claim 1.

Die Vorteile der Erfindung liegen insbesondere darin, daß die Falzklappenarbeitsabstände direkt in Abhängigkeit von der tatsächlichen Papierbahndicke eingestellt werden, so daß Einstellfehler, die bei einer Handverstellung vorkommen können, ausgeschlossen sind. Der Arbeitsgang, der die Falzklappeneinstellung beinhaltet, kenn entfallen.The advantages of the invention are, in particular, that the folding jaw working distances are set directly as a function of the actual paper web thickness, so that setting errors which can occur during manual adjustment are excluded. The operation that includes the jaw adjustment can be omitted.

Bei einer vollautomatischen, rechnergesteuerten Produktablaufplanung für eine Druckproduktion kann auch das Falzwerk mit einbezogen werden, da die Einstellung der Falzklappen voll automatisierbar ist. Die Steuerung der Falzklappen mittels ausschließlich rotierbaren Stellmitteln begünstigt die funktionalen Verhältnisse.In the case of fully automatic, computer-controlled product flow planning for a print production, the folder can also be included, since the setting of the jaws can be fully automated. The control of the jaws by means of exclusively rotatable actuators favors the functional conditions.

Ein Falzklappenzylinder 1 ist mittels Wälzlagern 2,3 in Seitengestellen 4,6 eines Falzapparates 7 gelagert. Der Falzklappenzylinder 1 besteht aus einer Zylinderwelle 8, einer aus zwei Trägerscheiben 9,11 bestehenden Trägereinrichtung für eine bewegliche Falzklappenreihe 12 und einer aus zwei Trägerscheiben 13,14 bestehenden Trägereinrichtung für eine unbewegliche Falzklappenreihe 16. Es können selbstverständlich auch mehrere Falzklappenreihen 12,16 vorgesehen werden. Der Einfachheit halber wird jedoch nur ein Falzklappenreihenpaar 12,16 beschrieben.A folding jaw cylinder 1 is supported by means of roller bearings 2, 3 in side frames 4, 6 of a folding device 7. The jaw cylinder 1 consists of a cylinder shaft 8, a carrier device consisting of two carrier disks 9, 11 for a movable row of folding jaws 12 and a carrier device consisting of two carrier disks 13, 14 for a stationary row of folding jaws 16. Of course, several rows of jaws 12, 16 can also be provided . For the sake of simplicity, however, only one pair of folding jaw rows 12, 16 is described.

Die Trägerscheiben 9,11,13,14 sind mittels Gleitlagern um die Zylinderwelle 8 schwenkbar und mittels nicht dargestellter Kupplungen drehfest mit der Zylinderwelle 8 verbindbar gelagert. Auf einem linken Ende der Zylinderwelle 8 sitzt fest aufgekeilt ein Antriebszahnrad 17 für den Falzklappenzylinder 1. Auf einem rechten Ende der Zylinderwelle 8 sitzt ebenfalls fest aufgekeilt ein Abtriebszahnrad 18.The carrier disks 9, 11, 13, 14 can be pivoted about the cylinder shaft 8 by means of slide bearings and can be connected to the cylinder shaft 8 in a rotationally fixed manner by means of couplings (not shown). On a left end of the Cylinder shaft 8 has a drive gear 17 for the jaw cylinder 1 firmly wedged. An output gear 18 is also wedged on a right end of the cylinder shaft 8.

Die Zylinderwelle 8 weist auf ihrer rechten Seite eine axiale Bohrung 19 auf, die sich bis über ca. ein Drittel der Zylinderwellenlänge erstreckt. Am Ende der axialen Bohrung 19 ist eine radiale Bohrung 21 vorgesehen. Die Bohrungen 19,21 dienen zur Aufnahme von wälzgelagerten Stellwellen 22,23, die an einer Umlenkstelle 24 mittels eines Kegelradsatzes 26, bestehend aus zwei ineinandergreifenden Kegelrädern, miteinander in Drehkraftübertragung stehen.The cylinder shaft 8 has on its right side an axial bore 19 which extends over approximately one third of the cylinder wavelength. At the end of the axial bore 19, a radial bore 21 is provided. The bores 19, 21 serve to receive actuating shafts 22, 23 with roller bearings, which are at a deflection point 24 by means of a bevel gear set 26, consisting of two intermeshing bevel gears, with each other in torque transmission.

In Verlängerung der radial verlaufenden Bohrung 21 ist ein Rohrstück 27 an die Zylinderwelle 8 angeschweißt. Das Rohrstück 27 dient als Festlager für eine Stellspindel 28, die an ihren Enden ein Rechts- und ein Linksgewinde aufweist.In extension of the radially extending bore 21, a pipe section 27 is welded to the cylinder shaft 8. The pipe section 27 serves as a fixed bearing for an adjusting spindle 28 which has a right-hand and a left-hand thread at its ends.

Die Stellwelle 28 steht ebenfalls mittels eines zweiten, aus zwei ineinandergreifenden Kegelräder bestehenden Kegelradsatzes 29 mit der radial angeordneten Stellwelle 23 in Drehkraftübertragung.The actuating shaft 28 is also in torque transmission with the radially arranged actuating shaft 23 by means of a second bevel gear set 29 consisting of two intermeshing bevel gears.

Die axiale Stellwelle 22 ragt mit ihrem rechten Ende aus der Bohrung 19 heraus und trägt an diesem Ende drehfest ein Antriebszahnrad 31, welches den gleichen Durchmesser aufweist wie das Abtriebszahnrad 18.The right-hand end of the axial actuating shaft 22 protrudes from the bore 19 and at this end carries a drive gear 31, which has the same diameter as the driven gear 18, in a rotationally fixed manner.

Die Stellspindel 28 steht mit ihren Links- und Rechtsgewindeenden in Schraubkontakt mit je einem Verstellträger 32,33. Die Verstellträger 32,33 sind jeweils in den Trägerscheiben 9,11; 13,14 in radial angeordneten Langlöchern 34 bis 37 gelagert. Durch die Anordnung der Verstellträger 32,33 in Langlöchern 34 bis 37 können Ausgleichsbewegungen durchgeführt werden, die notwendig sind, um die durch die Stellwelle 28 erzeugte Translationsbewegung in eine Rotationsbewegung der Trägerscheiben 9,11; 13,14 umzusetzen.The adjusting spindle 28 is in screw contact with one each with its left and right-hand thread ends Adjustment bracket 32.33. The adjustment carriers 32, 33 are each in the carrier disks 9, 11; 13,14 stored in radially arranged slots 34 to 37. Due to the arrangement of the adjustment carriers 32, 33 in elongated holes 34 to 37, compensatory movements can be carried out which are necessary to convert the translational movement generated by the adjusting shaft 28 into a rotational movement of the carrier disks 9, 11; 13.14 implement.

Eine Steuerkurve 38 ist in bekannter Weise am Seitengestell 4 befestigt. Auf dem Umfang läuft eine Steuerrolle 39 ab, die den Öffnungstakt der bewegbaren Falzklappen 12 steuert. Eine Stellbewegung für einen Arbeitsabstand a zwischen den Falzklappen 12, 16 wird über das Antriebszahnrad 31 eingeleitet.A control cam 38 is attached to the side frame 4 in a known manner. A control roller 39 runs on the circumference and controls the opening stroke of the movable folding jaws 12. An actuating movement for a working distance a between the jaws 12, 16 is initiated via the drive gear 31.

Das Antriebszahnrad 31 wird von einem Abtriebsteil 41 eines Verstellgetriebes 42 mittels eines ersten Zahnriemens 43 angetrieben.The drive gear 31 is driven by an output part 41 of an adjustment gear 42 by means of a first toothed belt 43.

Das Verstellgetriebe 42 weist außer dem Abtriebsteil 41 ein Antriebsteil 44 auf, das mittels eines zweiten Zahnriemens 46 mit dem Abtriebszahnrad 18 der Falzklappenzylinderwelle 8 in Antriebsverbindung steht und ein Steuerteil 47, das mittels eines dritten Zahnriemens 48 mit einem Antriebszahnrad 49 eines Stellmotors 51 und einem Antriebszahnrad 52 eines Istwertaufnehmers 53 in Antriebsverbindung steht (Fig. 5).The adjustment gear 42 has, in addition to the driven part 41, a drive part 44, which is in drive connection by means of a second toothed belt 46 with the driven gear 18 of the jaw cylinder shaft 8 and a control part 47, which is connected by means of a third toothed belt 48 with a drive gear 49 of a servomotor 51 and a drive gear 52 of an actual value sensor 53 is in drive connection (FIG. 5).

Der Stellmotor 51 erhält seine Stellbefehle in Form von elektrischen Signalen, die von einem Dreipunktregler 50 erzeugt werden.The servomotor 51 receives its positioning commands in the form of electrical signals that are generated by a three-point controller 50.

Fig. 6 zeigt die Verknüpfung von Ist- und Sollwerten zur Erzeugung des Stellwertes für den Stellmotor 51.6 shows the linking of actual and target values for generating the manipulated variable for the servomotor 51.

Der Dreipunktregler 50 ist mittels einer elektrischen Leitung mit dem Istwertaufnehmer 53 und einem Umschalter 54 verbunden. Der Umschalter 54 leitet einen Sollwert an den Dreipunktregler 50.The three-point controller 50 is connected to the actual value sensor 53 and a changeover switch 54 by means of an electrical line. The changeover switch 54 forwards a setpoint to the three-point controller 50.

Der Sollwert (Papierstrangdicke d) kann wahlweise mittels einer Eingabeeinrichtung eines Rechners 56 oder mittels eines Meßwertaufnehmers 57 eingegeben werden.The nominal value (paper strand thickness d) can be entered either by means of an input device of a computer 56 or by means of a measurement sensor 57.

Der Meßwertaufnehmer 57 mißt die Dicke d eines Papierstranges 58, der dem Falzapparat 7 zugeführt wird. Der Meßwertaufnehmer 57 ist in Papierstrangtransportrichtung gesehen hinter einer Überführwalze 61 und vor einem Zugwalzenpaar 62 angeordnet.The transducer 57 measures the thickness d of a strand of paper 58 which is fed to the folder 7. The transducer 57 is arranged behind a transfer roller 61 and in front of a pair of draw rollers 62, as seen in the direction of the paper strand.

In Fig. 7 sind mit 59 Falztrichter mit 63, 64 Zugwalzengruppen und mit 66 eine Umlenkwalze bezeichnet.In Fig. 7 with 59 formers with 63, 64 draw roller groups and with 66 a deflection roller.

Der Falzapparat 7 enthält beispielsweise einen Schneidzylinder 67, einen Sammelzylinder 68, den Falzklappenzylinder 7, einen Schaufelradausleger 69 und ein Transportband 70.The folder 7 contains, for example, a cutting cylinder 67, a collecting cylinder 68, the folder cylinder 7, a bucket wheel boom 69 and a conveyor belt 70.

Der Meßwertaufnehmer 57 besteht aus einer drehbar gelagerten, vorzugsweise verchromten Walze 71 und einer verchromten Meßrolle 72.The transducer 57 consists of a rotatably mounted, preferably chrome-plated roller 71 and a chrome-plated measuring roller 72.

Die Walze 71 ist in den Seitengestellen 4,6 gelagert.The roller 71 is mounted in the side frames 4, 6.

Die Meßrolle 72 ist am Ende eines Hebelarmes 73 drehbar gelagert. Dieser sitzt drehfest auf einer Welle 74, die schwenkbar in den Seitengestellen 4,6 gelagert ist.The measuring roller 72 is rotatable at the end of a lever arm 73 stored. This sits in a rotationally fixed manner on a shaft 74 which is pivotably mounted in the side frames 4, 6.

Der Papierstrang 58 wird zwischen der Walze 71 und der Meßrolle 72 hindurchgeführt, so daß die Meßrolle 72 je nach Papierstrangdicke d mehr oder weniger ausgelenkt wird, was in einer Schwenkbewegung der Welle 74 resultiert.The paper strand 58 is passed between the roller 71 and the measuring roller 72, so that the measuring roller 72 is deflected more or less depending on the paper strand thickness d, which results in a pivoting movement of the shaft 74.

Auf einem durch das Seitengestell 4 hindurchragenden Ende der Welle 74 ist ein Stellhebel 76 drehfest angeordnet.An adjusting lever 76 is arranged in a rotationally fixed manner on an end of the shaft 74 which projects through the side frame 4.

Mit dem Stellhebel 76 ist ca. mittig ein Wegaufnehmer (z.B. Tauchspulgerät) 77 gelenkig verbunden, das mit einem Ende schwenkbar an einer Gestellplatte 78 des Meßwertaufnehmers 57 angeordnet ist.A displacement transducer (e.g. moving coil device) 77 is pivotally connected to the actuating lever 76 approximately in the center and is pivotally arranged at one end on a frame plate 78 of the measurement transducer 57.

An einem Ende des Stellhebels 76 ist eine an der Gestellplatte 78 befestigte Rückholfeder 79 vorgesehen.A return spring 79 fastened to the frame plate 78 is provided at one end of the adjusting lever 76.

Zwei an der Gestellplatte 78 befestigte, einstellbare Anschläge 81,82 begrenzen den Schwenkwinkel des Stellhebels 76 und damit die Auslenkung der Meßrolle 72. Die maximale Auslenkung kann z.B. in Folge eines Bahnrisses mit Papierbahnstopfung erreicht werden. Die Anschläge 81,82 schützen in diesem Fall das Tauchspulgerät 77 vor einer Zerstörung.Two adjustable stops 81, 82 fastened to the frame plate 78 limit the pivoting angle of the actuating lever 76 and thus the deflection of the measuring roller 72. The maximum deflection can e.g. as a result of a web break with paper web stuffing. In this case, the stops 81, 82 protect the plunger winding device 77 from being destroyed.

Die Gestellplatte 78 ist um die Welle 74 zwischen Seitengestell 4 und Stellhebel 76 schwenkbar gelagert. Ein Verschwenken der Gestellplatte 78 erfolgt durch einen am Seitengestell 4 befestigten Luftzylinder 84, der an einem Ende der Gestellplatte 78 angreift.The frame plate 78 is pivotally mounted about the shaft 74 between the side frame 4 and the actuating lever 76. The frame plate 78 is pivoted by means of an air cylinder 84 which is fastened to the side frame 4 and which engages at one end of the frame plate 78.

Ein am Seitengestell 4 befestigter einstellbarer Anschlag 83 begrenzt die Lage der Gestellplatte 78 für eine Nullage von Meßrolle 72 zu Walze 71. In der Nullage stehen die Umfangsflächen von Walze 71 und Meßrolle 72 in Berührung, d.h. die Papierstrangdicke d ist gleich null.An adjustable stop 83 attached to the side frame 4 limits the position of the frame plate 78 for a zero position from the measuring roller 72 to the roller 71. In the zero position, the peripheral surfaces of the roller 71 and the measuring roller 72 are in contact, i.e. the paper strand thickness d is zero.

Der Luftzylinder 84 ist an einer Außenseite des Seitengestells 4 gelenkig befestigt und mittels eines Schaltventils 86 mit einer Druckmittelerzeugungsquelle 87 verbunden.The air cylinder 84 is articulated on an outside of the side frame 4 and connected to a pressure medium generation source 87 by means of a switching valve 86.

Selbstverständlich können anstatt des Tauchspulgerätes 77 auch andere Wegaufnehmer eingesetzt werden. Hierbei bieten sich gleichermaßen berührungsfreie und berührungsbehaftete Weg-Meßeinrichtungen an.Of course, other displacement transducers can also be used instead of the plunger winding device 77. Here, non-contact and touch-sensitive displacement measuring devices are equally suitable.

Es ist möglich, mittels einer nicht dargestellten Eingabevorrichtung des Rechners 56 einen Sollwert für den Falzklappenarbeitsabstand a vorzugeben, so daß mit der beschriebenen Einrichtung eine produktionsabhängige Voreinstellung des Falzapparates 7 möglich ist. Wahlweise kann dieser Sollwert auch durch Messung der Papierstrangdicke d ermittelt und nach einem Soll-Istwertvergleich als Stellbefehl an den Stellmotor 51 weitergeleitet werden.It is possible to specify a target value for the folding jaw working distance a by means of an input device, not shown, of the computer 56, so that a production-dependent presetting of the folding apparatus 7 is possible with the device described. Optionally, this setpoint can also be determined by measuring the paper strand thickness d and, after a setpoint / actual value comparison, can be forwarded to the servomotor 51 as a command.

Zur Messung der Papierstrangdicke d wird die Meßrolle 72 an die stationäre Walze 71 mittels des Luftzylinders 84 angestellt. Der Luftzylinder 84 verschwenkt die Gestellplatte 78 gegen den Anschlag 83. Die Meßrolle 72 wird entsprechend mitverschwenkt, bis sie an dem Papierstrang 58 anliegt. Der restliche Verschwenkweg bis zum Anliegen der Gestellplatte 78 am Anschlag 83 wird durch eine relative Schwenkbewegung des Stellhebels 76 aufgenommen.To measure the paper strand thickness d, the measuring roller 72 is placed against the stationary roller 71 by means of the air cylinder 84. The air cylinder 84 pivots the frame plate 78 against the stop 83. The measuring roller 72 is pivoted accordingly until it rests on the paper strand 58. The remaining pivoting path until the frame plate 78 bears against the stop 83 by a relative pivoting movement of the actuating lever 76 is added.

Ein Tauchanker des Tauchspulgerätes 77 wird je nach Schwenkbewegung des Stellhebels 76 relativ zur Gestellplatte 78 entsprechend weit in das Tauchspulgerät 77 hineingeschoben. Ein durch die Schiebebewegung injiziertes Spannungssignal wird dem Dreipunktregler 50 als meßabhängiger Sollwert zugeführt. Nach einem Vergleich dieses Sollwertes mit dem durch den als Drehimpulsgeber ausgeführten Istwertaufnehmer 53 ermittelten Istwert wird ein Stellwert gebildet und dieser als Spannungssignal dem Stellmotor 51 zugeführt.Depending on the pivoting movement of the actuating lever 76 relative to the frame plate 78, a plunger anchor of the plunger device 77 is pushed correspondingly far into the plunger device 77. A voltage signal injected by the sliding movement is fed to the three-point controller 50 as a measurement-dependent setpoint. After a comparison of this target value with the actual value determined by the actual value sensor 53 designed as a rotary pulse generator, a manipulated value is formed and this is fed to the servomotor 51 as a voltage signal.

Der Stellmotor 51 dreht sein Antriebszahnrad 49 je nach Betrag und Richtung des Stellwertes mehr oder weniger rechts oder links herum. Durch die Riemenverbindung 48 des Stellmotors 51 mit dem Steuerteil 47 des Verstellgetriebes 42 wird während der Drehung des Steuerteils 47 eine Übersetzung zwischen Antriebsteil 41 und Abtriebsteil 44 erzeugt. Diese Übersetzung führt zu einer Relativbewegung zwischen An- und Abtriebszahnrad 31,18 und damit zu einer Rotation der Stellwelle 23 um ihre Rotationsachse 88.The servomotor 51 rotates its drive gear 49 to the right or left depending on the amount and direction of the manipulated value. Through the belt connection 48 of the servomotor 51 with the control part 47 of the adjustment gear 42, a translation between the drive part 41 and the driven part 44 is generated during the rotation of the control part 47. This translation leads to a relative movement between the input and output gear 31, 18 and thus to a rotation of the actuating shaft 23 about its axis of rotation 88.

Wenn keine Verstellung erfolgt, rotiert die Stellwelle 22 synchron zur Maschinengeschwindigkeit, während die Stellwelle 23, bezogen auf ihre eigene Rotationsachse 88, stillsteht.If no adjustment is made, the actuating shaft 22 rotates synchronously with the machine speed, while the actuating shaft 23 is stationary with respect to its own axis of rotation 88.

Durch die Drehung der Stellspindel 28, die von der Stellwelle 23 mittels des Kegelradsatzes 29 erzeugt wird, werden die Trägerscheiben 9,11 gegen die Trägerscheiben 13, 14 hin- bzw. von ihnen wegverschwenkt.As a result of the rotation of the adjusting spindle 28, which is generated by the adjusting shaft 23 by means of the bevel gear set 29, the carrier disks 9, 11 are pivoted towards or away from the carrier disks 13, 14.

Hierbei greift jeweils ein Gewindeende 92;93 der Stellwelle 28 in eine Gewindebohrung 94;96 eines Bolzens 97;98 ein. Der Bolzen 97;98 ist in den Verstellträger 32;33 eingepaßt. Jeweils eine in Achsrichtung der Stellwelle 28 verlaufende Bohrung 99,101 in dem Verstellträger 32;33 umhüllt koaxial die Gewindeenden 92,93, so daß die Gewindeenden 92,93 in die Gewindebohrungen 94;96 der Bolzen 97;98 eingreifen können.In this case, a threaded end 92; 93 of the actuating shaft 28 engages in a threaded bore 94; 96 of a bolt 97; 98. The bolt 97, 98 is fitted into the adjustment support 32, 33. In each case a bore 99, 101 running in the axial direction of the adjusting shaft 28 in the adjustment support 32; 33 coaxially envelops the threaded ends 92, 93 so that the threaded ends 92, 93 can engage in the threaded bores 94, 96 of the bolts 97, 98.

Jeweils ein Axiallager 102;103 schützt die Kegelräder des Kegelradsatzes 29 vor Axialbelastungen, verursacht durch Schwenkbewegungen der Trägerscheiben 9,11,13,14.In each case one axial bearing 102; 103 protects the bevel gears of the bevel gear set 29 against axial loads, caused by pivoting movements of the carrier disks 9, 11, 13, 14.

In den Trägerscheiben 9,11 ist eine Falzklappenwelle 104 schwenkbar gelagert. Die Falzklappen 12 sind in Abständen auf der Falzklappenwelle 104 befestigt, so daß sie synchron mit der Falzklappenwelle 104 verschwenkt werden. An einem linken Ende ragt die Falzklappenwelle 104 durch die Trägerscheibe 9 hindurch und trägt auf diesem Ende fest aufgekeilt eine Halterung 106 für die Steuerrolle 39.A jaw shaft 104 is pivotally mounted in the carrier disks 9, 11. The jaws 12 are fixed at intervals on the jaw shaft 104 so that they are pivoted synchronously with the jaw shaft 104. At a left end, the jaw flap shaft 104 projects through the carrier disk 9 and carries a bracket 106 for the control roller 39, which is firmly wedged on this end.

Die Trägerscheiben 13,14 weisen an ihrem Umfang eine Aufnahme 107 für eine Falzklappenleiste 108 auf. Die Falzklappen 16 sind in Abständen mit der Falzklappenleiste 108 verschraubt. Eine Bewegung der Falzklappen 16 erfolgt nur gemeinsam mit den Trägerscheiben 13,14.The carrier disks 13, 14 have a receptacle 107 for a folding jaw strip 108 on their circumference. The jaws 16 are bolted to the jaw strip 108 at intervals. The jaws 16 only move together with the carrier disks 13, 14.
