Description

Die Erfindung betrifft ein Verfahren zur einsteckweisen Beschickung von auf umlaufenden Sammelträgern einer Sammelvorrichtung zu Druckprodukten gesammtelten, mehrblättrigen Druckbogen mit wenigstens einer Beilage gemäss dem Oberbegriff von Patentanspruch 1 und eine Einrichtung zu dessen Durchführung. The invention relates to a method for plug-in loading of rotating collection carriers of a collection device multi-sheet printed sheets collected for printed products with at least one supplement according to the preamble of Claim 1 and a device for its implementation.

Bei Sammelheftern der Firma Müller Martini mit einer Sammelstrecke als Sammelträger für Druckbogen ist es bekannt, während dem Sammelvorgang mit einem Beilagenanleger oder sog. Cardfeeder der Marke simproducts eine Beilage zwischen zwei Druckbogen einzubringen. Dies geschieht dadurch, dass der nächstfolgende Druckbogen zunächst über dem der Sammelstrecke zuvor zugeführten Druckbogen auf einer Hilfsauflage abgelegt und danach mit dem bzw. den darunterliegenden Druckbogen weitergefördert wird, wobei auf dem weiteren Förderweg der eine seitlich herunterhängende Teil des oben liegenden Druckbogens durch eine Führungsvorrichtung angehoben wird, um mit dem darunter liegenden Druckbogen eine sich zum Falz hin verengende Öffnung bilden zu können, die der Aufnahme einer senkrecht zur Förderrichtung zugeführten Beilage wie Karte, Druckschrift oder dgl. dient. For saddle stitchers from the Muller Martini company with a collection section as a collective carrier for printed sheets it is known during the collecting process with an insert feeder or so-called. Card feeders from the simproducts brand insert between two Introduce printed sheets. This happens because the next following printed sheet first over that of the collecting line previously printed sheets are placed on an auxiliary support and then conveyed further with the printed sheet (s) below is, with the one part of the printed sheet hanging down on the side is lifted by a guide device to with the underneath   lying sheet a narrowing towards the fold To be able to form the opening perpendicular to the recording Supplement fed to the conveying direction, such as a card, printed matter or the like.

Eine solche Konstruktion ist bei den verschiedenen Sammelheftern nur beschränkt anwendbar, insbesondere wenn hohe Anforderungen an die Produktionsleistung gestellt sind und unterschiedlich formatierte Beilagen zugeführt werden. Such a construction is in the various saddle stitchers can only be used to a limited extent, especially if high demands are made are placed on the production output and different formatted supplements are fed.

Durch die US - A - 4'200'275 ist ein Sammelhefter bekannt, bei dem die Druckbogen von einem Stapel über eine am Umfang Greifer aufweisenden, rotierenden Trommel einem Sammelförderer zugeführt werden. Auf ihrem Weg zur Querstange am Sammelförderer öffnen sich die Druckbogen durch Loslösen eines Schenkels von der Trommel durch die wirkende Schwerkraft, sodass ein Anleger eine Beilage in Bewegungsrichtung des Sammelförderers zuführen und die Querstange mit grösserer Geschwindigkeit an die innere Falzkante des Druckbogens heranfahren kann. A saddle stitcher is known from US - A - 4,200,275 which the printed sheets from a stack on a circumferential gripper having, rotating drum a collecting conveyor be fed. On their way to the crossbar on the collecting conveyor the printed sheets open by releasing one leg from the drum by gravity, so that a Feed a supplement in the direction of movement of the collecting conveyor feed and the crossbar at a higher speed can move up the inner fold edge of the sheet.

Aufgabe der vorliegenden Erfindung ist es deshalb, ein Verfahren und eine Einrichtung zu entwickeln, die höheren Ansprüchen als bisher gewachsen sind, ohne dass darunter die Qualität der Druckprodukte leidet. The object of the present invention is therefore a method and to develop a facility that meets higher demands have grown than before without undermining the quality of the Print products suffer.

Erfindungsgemäss wird diese Aufgabe nach den im Kennzeichen der Patentansprüche 1 und 3 enthaltenen Merkmalen gelöst. Auf diese Weise lassen sich Richtungswechsel zum Zeitpunkt des Beschickens der Druckprodukte mit Beilagen auf dem Verarbeitungsweg vermeiden. According to the invention, this task according to the in the mark of claims 1 and 3 contained features solved. In this way, changes of direction at the time of Loading the printed products with supplements on the processing route avoid.

Überdies wird damit ein schonenderes Verarbeitungsverfahren gewählt. In addition, it becomes a gentler processing method chosen.  

Weiter lässt sich das erfindungsgemässe Verarbeitungsprinzip auch als klassische Einsteckmaschine ungehefteter Druckprodukte verwenden. The processing principle according to the invention can also be used also as a classic inserting machine for unstitched printed products use.

Nachfolgend werden das erfindungsgemässe Verfahren und eine Einrichtung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

The method according to the invention and a device are explained in more detail below on the basis of an exemplary embodiment shown in the drawing. Show it:
Fig. 1
is a schematic side view of the inventive device and
Fig. 2
a section through the device of FIG. 1 along the line II - II.

Fig. 1 veranschaulicht eine in einem Gestell befestigte Einrichtung 1 für die Verarbeitung von Druckbogen, insbesondere zur Beschickung von zu Druckprodukten 2 gesammelten, mehrblättrigen Druckbogen mit wenigstens einer Beilage 3, die an der den letzten bzw. der letzten Falzkante gegenüberliegenden Kante des Druckproduktes 2 zugeführt werden.
Die Druckprodukte 2 werden an einer durch mehrere, in Abständen an einem Zugmittel 4 quer zur Förderrichtung sich erstreckenden Sammelträgern 5 eines umlaufenden Förderorgans 6 rittlings übereinandergesteckt gesammelt, wozu nicht dargestellte, in Serie geschaltete Anleger für die unterschiedlich bedruckten Druckbogen vorgesehen sind, welche entlang des oberen Trums bzw. im Beschickungsbereich des Förderorgans 6 angeordnet sind.
An die Druckbogenanleger schliesst bei dem erörteten Ausführungsbeispiel ein Heftapparat 7 an, der von dem mit Sammelträgern 5 versehenen Zugmittel 4 bzw. der Förderorgan 6 passiert wird. Das endlose Zugmittel 4 läuft um wenigstens zwei parallele Achsen um, von denen die eine 8 zur Lagerung eines Heftrades 9 des Heftapparates 7 ausgebildet ist, welches im Abstand der Sammelträger 5 der Fördervorrichtung 6 am Umfang verteilte, antreib- bzw. betätigbare Umbieger 10 aufweist. Diese Umbieger 10 oder die Umbiegevorrichtung insgesamt an dem Heftrad 9, ist entsprechend der Anzahl der in den Falz eines Druckproduktes 2 zu versetzenden Klammern zumindest in zweifacher Ausführung über die Auflagelänge eines Sammelträgers 5 vorgesehen. Zum besseren Verständnis sind die letzten drei Sammelträger ohne aufgelegte Druckbogen dargestellt.
Angepasst an die dargestellte Situation weist der Heftapparat 7 jeweils Heftkopfpaare 11 auf, die um eine parallele Achse 12 rotieren und die in dem Näherungsbereich zu der Umlaufbahn der Sammelträger 5, mit letzteren eine kurze gemeinsame Heftstrecke bilden.
Die Heftstrecke ist hier jedoch kein bedeutender Bestandteil der erfindungsgemässen Einrichtung 1 und wird u.a. in der DE - A - 36 16 566 oder der EP - A - 0 546 326 näher erklärt. Anstelle der an einem Zugmittel 4 um zwei Achsen umlaufenden Sammelträger 5 könnte die Fördervorrichtung 6 auch trommelförmig - wie in der DE - A - 36 16 566 oder der EP - A - 0 399 317 beschrieben - ausgebildet sein, wobei sich die Sammelträger 5 als sogenannte Sammelstrecken achssymetrisch entlang einer Drehachse erstrecken und ihre Abgabeenden münden in einen Heftapparat, der die trommelförmig angeordneten Sammelstrecken im Längenbereich der Heftung umgibt oder als Rotationsheftapparat, mit der Sammeltrommel "kämmend" zusammenwirkt.
Nachzuholen ist, dass bei der vorliegenden Ausführung, vor der Heftstrecke ein Einlaufabschnitt 13 besteht, auf welchem die Umbieger 10 an dem Heftrad 9 und die ihnen zugeordneten Sammelträger 5 sich zu einer stabilden Einheit ineinanderfügen, d.h. dass die Umbieger 10 von unten in die Sammelträger 5 einlaufen.
Der Heftapparat 7 weist mehrere, durch radiale Striche angedeutete, sternförmig angeordnete Heftköpfe 11 auf, die um die Achse 12 rotierend angetrieben sind. Die Achse 12 verläuft etwa parallel zur Achse 8 des Heftrades 9.
Auf dem weiteren Verlauf der Sammelträger 5, nachdem die Druckbogen zu einem Druckprodukt 2 geheftet worden sind, werden letztere, geführt durch das Heftrad 9, an eine aus Greifzangen 15 bestehende Fördervorrichtung 14 abgesetzt, in deren Näherungsbereich sich eine Übergabestelle 16 bildet.
An dieser Stelle erfassen die Greifzangen 15 der Fördervorrichtung 14 die Druckprodukte 2 etwa an dem Falz und heben sie von dem Sammelträger 5 ab, dadurch, dass sich die Fortbewegungsrichtung der Greifzangen 15 nicht nur durch die Richtungsänderung des Heftrades 9, sondern durch einen geringen Knick zusätzlich vom Heftrad 9 entfernt.
Fig. 1 illustrates a device 1 mounted in a frame for processing printed sheets, in particular for loading multi-sheet printed sheets collected for printed products 2 with at least one insert 3, which is fed to the edge of the printed product 2 opposite the last or last folded edge will.
The printed products 2 are collected astride one another by a plurality of collecting supports 5 of a rotating conveying member 6, which are spaced on a traction means 4 and extend transversely to the conveying direction, for which purpose not shown, series-connected feeders are provided for the differently printed printed sheets, which run along the upper one Runs or in the loading area of the conveyor member 6 are arranged.
In the exemplary embodiment discussed, a binding device 7 adjoins the printed sheet feeder, which is passed by the traction means 4 provided with collecting supports 5 or the conveying element 6. The endless traction device 4 runs around at least two parallel axes, one of which is designed 8 for mounting a stitching wheel 9 of the stitching device 7, which has spaced, drivable or actuable benders 10 distributed around the periphery of the collecting carriers 5 of the conveying device 6. This bending device 10 or the bending device as a whole on the stapling wheel 9 is provided in accordance with the number of staples to be placed in the fold of a printed product 2, at least in duplicate over the support length of a collecting support 5. For a better understanding, the last three collection carriers are shown without printed sheets.
Adapted to the situation shown, the stapling apparatus 7 has pairs of stapling heads 11, which rotate about a parallel axis 12 and which form a short common stapling path with the latter in the vicinity of the orbit of the collecting carriers 5.
However, the stitching section is not an important component of the device 1 according to the invention and is explained in more detail in DE-A-36 16 566 or EP-A-0 546 326, among others. Instead of the carrier 5 rotating around a traction device 4 about two axes, the conveying device 6 could also be drum-shaped - as described in DE-A-36 16 566 or EP-A-0 399 317 - the carrier 5 being so-called Symmetrically extend the collecting sections along an axis of rotation and their delivery ends open into a stapler which surrounds the collecting sections arranged in the form of a drum in the length region of the stapling or as a rotary stapling device, "intermeshing" with the collecting drum.
It must be made up for in the present embodiment that there is an inlet section 13 in front of the stitching section, on which the benders 10 on the stitching wheel 9 and the collecting carriers 5 assigned to them fit into one another to form a stable unit, that is to say that the benders 10 enter the collecting carriers 5 from below break in.
The stapler 7 has a plurality of star-shaped stapling heads 11, indicated by radial lines, which are driven to rotate about the axis 12. The axis 12 runs approximately parallel to the axis 8 of the stitching wheel 9.
On the further course of the collecting carriers 5, after the printed sheets have been stapled into a printed product 2, the latter, guided by the stitching wheel 9, are placed on a conveyor device 14 consisting of gripping tongs 15, in the vicinity of which a transfer point 16 is formed.
At this point, the gripping tongs 15 of the conveying device 14 grasp the printed products 2 approximately at the fold and lift them off the collecting carrier 5, because the direction of travel of the gripping tongs 15 does not only change due to the change in direction of the stitching wheel 9, but also due to a slight kink removed from stitching bike 9.

Während der Entnahme der Druckprodukte 2 von den Sammelträgern 5 tritt die Wirkung einer Trennvorrichtung 17 in Kraft, die den gespreizten Zustand der Druckprodukte 2 von den Sammelträgern 5 weiter aufrecht erhält oder mit der die Druckprodukte 2 nach dem Verlassen der Sammelträger 5 wieder in eine geöffnete Beschickungsform versetzt werden können. During the removal of the printed products 2 from the collection carriers 5, the action of a separating device 17 takes effect the spread state of the printed products 2 from the collection carriers 5 is maintained or with which the printed products 2 after leaving the collecting carrier 5 again in an open Feed form can be moved.

Eine mögliche Ausführungsform einer Trennvorrichtung 17 ist in der Fig. 2 etwas näher dargestellt. Zwei durch eine Drehachse 18 verbundene Scheiben 19 tragen an ihrem Umfang verteilt jeweils eine einem Sammelträger 5 zugeordnete Trennvorrichtung 15, die hinsichtlich ihrer senkrecht zur Förderrichtung vorgesehenen Auslenkung mechanisch, hydraulisch, pneumatisch oder elektrisch antreibbar ist. Bei dem vorliegenden, unterhalb des Falzes der Druckprodukte 2 in diese wirksam eindringenden Trennvorrichtung 17 handelt es sich um eine dachförmige Konstruktion 20, die bezüglich Zustellrichtung sich keilfömig verjüngend ausgebildet ist. Die Betätigung der dachförmigen Konstruktion erfolgt gemäss Darstellung durch eine von einer Steuerkurve 21 angetriebenen Stange 22, deren Rückhub beispielsweise durch eine Feder (nicht gezeichnet) erreicht wird. A possible embodiment of a separating device 17 is shown in FIG 2 a little closer. Two through an axis of rotation 18 connected discs 19 each distributed around their circumference a separating device assigned to a collecting carrier 5 15, which are provided with respect to their perpendicular to the conveying direction Mechanical, hydraulic, pneumatic or is electrically driven. In the present, below the Fold the printed products 2 effectively penetrating them Separating device 17 is a roof-shaped construction 20, which is wedge-shaped with respect to the feed direction is tapered. The actuation of the roof-shaped Construction is carried out as shown by one of one Control cam 21 driven rod 22, the return stroke for example   is achieved by a spring (not shown).

Innerhalb der Scheiben 19, jedoch durch die Drehachse 18 mit diesen fest verbunden, sitzt ein Umlenkrad 23 der Fördervorrichtung 14, von welcher eine Greifzange 15 erkennbar ist. Die Greifzange 15 besteht aus einer starren 24 und einer betätigbaren Klemmbacke 25, wozu ein Hebel 26 vorgesehen ist, dessen Betätigung u.a. zum Öffnen der Greifzange 15 mit einer nicht dargestellten Steuervorrichtung - bspw. einer stationären Steuerkurve - vor dem Erfassen der Druckprodukte 2 und zum Schliessen der Greifzange 15 nach der Übergabe der Druckprodukte 2 ausgelöst wird (siehe Fig. 1).
Die Fig. 1 lässt überdies erkennen, dass die von den Sammelträgern 5 abgehobenen Druckprodukte 2 in geöffneter Form weitergefördert werden, wobei der in Förderrichtung vordere Druckprodukteteil von der eingetauchten Konstruktion 20 der Trennvorrichtung 17 gestützt wird und der nachlaufende Druckprodukteteil aufgrund der Gravitation hinunterhängen kann, derart, dass zwischen beiden Teilen eine Beschickungsöffnung entsteht.
Die Trennvorrichtung 17 kann so ausgebildet sein, dass die zwischen die Seitenteile eines abgehobenen Druckproduktes 2 eingetauchte Trennvorrichtung 17 durch eine eigens zugeordnete Antriebsvorrichtung (nicht dargestellt), den entsprechenden Druckprodukteteil nach oben auslenkt.
Um auf dem weiteren Förderweg die Bewegungsbahn 27 einer von einem Anleger 29 angetriebenen Beilage 3 quer durchsetzen zu können, ist der weitere Förderweg nach der Entnahme der Druckprodukte 2 von dem Heftrad 9 durch das Umlenkrad 23 unterschlächtig ausgebildet. Auf diesem unterschlächtigen Förderabschnitt sind die Druckprodukte 2 geöffnet und zumindest beim Passieren der Bewegungsbahn 27 der Beilagen 3, mündet letztere in die durch die gespreizten Druckprodukteteile gebildete Öffnung, in die die Beilage 3 wurfartig versetzt wird, so dass sie in dem durch den Falz gebildeten Spaltende eingesteckt verharrt.
A deflection wheel 23 of the conveying device 14, of which a gripping pliers 15 can be seen, is located within the disks 19, but firmly connected to them by the axis of rotation 18. The gripping pliers 15 consist of a rigid 24 and an actuatable clamping jaw 25, for which purpose a lever 26 is provided, the actuation of which, inter alia, for opening the gripping pliers 15 with a control device (not shown) - for example a stationary control curve - before the printed products 2 are grasped and for closing the gripper 15 is triggered after the transfer of the printed products 2 (see Fig. 1).
1 also shows that the printed products 2 lifted off the collecting carriers 5 are conveyed further in an open form, the printed product part in the conveying direction being supported by the immersed construction 20 of the separating device 17 and the trailing printed product part being able to hang down due to gravity, in such a way that a loading opening is created between the two parts.
The separating device 17 can be designed in such a way that the separating device 17, which is immersed between the side parts of a lifted printed product 2, deflects the corresponding printed product part upwards by a specially assigned drive device (not shown).
In order to be able to transversely pass through the movement path 27 of an insert 3 driven by a feeder 29 on the further conveying path, the further conveying path after the removal of the printed products 2 from the stapling wheel 9 is undershot by the deflecting wheel 23. On this undershot conveying section, the printed products 2 are open and, at least when passing the movement path 27 of the supplements 3, the latter opens into the opening formed by the spread printed product parts, into which the supplement 3 is displaced like a litter, so that it is in the gap end formed by the fold inserted stuck.

Zur Begünstigung des anschliessenden Klemmeffektes innerhalb des Falzes eines für die Beilage 3 vorgesehenen Druckproduktes 2, ist die Klemmkraft der Greifzangen 15 zumindest während der Zeit der Beschickung durch eine die Druckprodukte 2 etwa in den Endbereichen des Falzes haltende Hilfsklammervorrichtung (mit 28 angedeutet) wenigstens teilweise gesteuert abzulösen. Dadurch wird es möglich sein, die Schliesskraft der Greifzange 15 unmittelbar vor dem Beschicken mit einer Beilage 3 soweit zu mindern, so dass die schmalere Beilage 3 oder Beilagen tiefer in den Falz eindringen können, wodurch nach der Beschickung durch den Falz eine bessere Haftung entstehen kann. Diese Zusatzmassnahme erweist sich insbesondere dann als vorteilhaft, wenn mehrere Beilagen 3 dem Druckprodukt 2 zuzuführen sind.
Für die Beschickung der Beilagen 3 ist ein an sich bekannter Anleger 29 vorgesehen, der die in einem Stapelmagazin vorkommenden Karten, Beutel, Muster oder dgl. vorerst vereinzelt der Bewegungsbahn 27 zuführt, wo sie von einem Förderer 30, der beispielsweise am Förderende mit einer Beschleunigungsvorrichtung 31 ausgestattet ist, wurfartig an die Druckprodukte 2 übergeben werden.
In order to favor the subsequent clamping effect within the fold of a printed product 2 provided for the insert 3, the clamping force of the gripping tongs 15 is at least partially controlled at least during the time of loading by an auxiliary clamping device (indicated at 28) holding the printed products 2 approximately in the end regions of the fold to replace. This will make it possible to reduce the closing force of the gripper 15 immediately before loading with an insert 3, so that the narrower insert 3 or inserts can penetrate deeper into the fold, which can result in better adhesion after loading by the fold . This additional measure proves to be particularly advantageous if a plurality of inserts 3 are to be fed to the printed product 2.
For loading the inserts 3, a feeder 29 known per se is provided, which feeds the cards, bags, samples or the like occurring in a stack magazine occasionally to the movement path 27, where they are fed by a conveyor 30, for example at the end of the conveyor with an acceleration device 31 is equipped to be transferred to the printed products 2 in a cube-like manner.

Für die Beschickung mehrerer Beilagen 3 können mehrere Anleger 29 in Serie oder parallel, entlang einer einen verlängerten Beschickungsbereich aufweisenden Fördervorrichtung 14 geschaltet sein, d.h. ersteren Falls werden mehrere Beilagen 3 am Ende des Förderers 30 den Druckprodukten 2 gebündelt zugeführt oder bei einer Parallelschaltung der Anleger 29, werden die Beilagen 3 nacheinander den geöffneten Druckprodukten 2 zugeführt. Several feeders can be used for loading several inserts 3 29 in series or parallel, along an extended one Feeding area having conveyor device 14 switched be, i.e. in the former case, several supplements 3 am End of the conveyor 30 fed to the printed products 2 bundled or if the feeder 29 is connected in parallel, the Supplements 3 are fed to the opened printed products 2 one after the other.

Claims (14)

  1. Method for loading at least one insert between multi-page printed sheets assembled into printed products on circulating gathering brackets of a gathering device, the said inserts being fed to the printed sheet at the open edge opposite the last folded edge, characterised in that the assembled printed sheets are gripped on the fold side and removed from the gathering brackets with at least partly separated lateral portions, and along the rest of their journey they are turned with their open edge towards a feeder for inserts and are conveyed past the feeder.
  2. Method according to claim 1, characterised in that the printed products that are to be loaded with inserts are in the form of printed sheets deposited astride one another and stapled in the fold.
  3. Arrangement for implementing the method according to claims 1 and 2, characterised by the provision of gathering brackets (5) which circulate at regular intervals and with which are coordinated a respective one of a number of gripping pliers (15) which are affixed to a traction mechanism of a conveying device (14), the gripping pliers (15) gripping the printed products (2) at a handover point (16) formed with a respective circulating gathering bracket (5) and removing them from the gathering brackets (5) with the intervention of a separating device (17) inside the folded edge, in such a manner that along the rest of their journey the printed products (2), opened and ready to be loaded, cross more or less at right angles the path (27) being travelled by at least one insert (3) being delivered by a feeder (29).
  4. Arrangement according to claim 3, for loading inserts into printed products manufactured by means of a gather-stitcher from a plurality of printed sheets, characterised by the provision of gathering brackets (5) which circulate at regular intervals and pass through a stitcher (7) and with which are coordinated a respective one of a number of gripping pliers (15) which are affixed to a traction mechanism of a conveying device (14), the gripping pliers (15) gripping the printed products (2) at a handover point (16) formed with a respective circulating gathering bracket (5) and removing them from the gathering brackets (5) with the intervention of a separating device (17) inside the folded edge, in such a manner that along the rest of their journey the printed products (2), opened and ready to be loaded, cross the path (27) being travelled by at least one insert (3) being delivered by a feeder (29).
  5. Arrangement according to claims 3 or 4, characterised in that further along the line is an undershot conveyor section formed by a diverting axis (18) and crossing the path (27) being travelled by an insert (3).
  6. Arrangement according to claim 5, in which the gathering brackets are fastened in axially symmetrical manner to a hub and are in the form of a staple bending device (10), characterised in that the separator (17), which is adapted to be displaced into the printed products (2) at the head and foot beneath the fold and which is driven in the direction of advance, is coordinated with the gripping pliers (15) in the region of the handover point (16) for the printed products (2), which pliers extend more or less at a tangent to the path along which the gathering brackets (5) circulate.
  7. Arrangement according to claim 6, characterised in that the separator (17) is driven so as to circulate coaxially to the diverting axis (18) formed by the rotational axis of a diverting wheel (23).
  8. Arrangement according to claim 7, characterised in that the separator (17) is adapted to be rendered inoperative once the path (27) travelled by the inserts (3) has been crossed.
  9. Arrangement according to claim 8, characterised in that the path (27) travelled by the inserts (3) is in the form of an accelerating device (31).
  10. Arrangement according to claim 9, characterised in that the path (27) travelled by the inserts (3) and a horizontal plane extending in the diverting axis (18) form an acute angle in the undershot conveying section of the conveying device (14).
  11. Arrangement according to claim 5, characterised in that at the handover point (16) for the printed products (2) the traction mechanism for the gripping pliers (15) features an increasingly remote direction of movement (2) from the path along which the gathering brackets (5) circulate.
  12. Arrangement according to claim 5, characterised in that after the undershot conveying section the traction mechanism for the gripping pliers (15) extends more or less vertically upwards.
  13. Arrangement according to claim 5, characterised in that in the loading zone, or rather on the undershot conveying section, an auxiliary staple device (28) with a squeezing action against the sides of the gripping pliers (15) onto the fold of a printed product (2) is coordinated with the gripping pliers (15).
  14. Arrangement according to claim 4, characterised in that a driving mechanism exerting an opening action on the printed products (2) is coordinated with the separator (17).
