Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Einhängen klebegebundener Blattstapel in Umschläge, bestehend aus einer den Rückenbereich des Umschlages gegen den Blattstapelrücken andrückenden Preßplatte und aus zwei längs der Preßplattenoberseite gegeneinander beweglichen Falzbacken, mit deren Hilfe die seitlichen Überstände des Umschlages gegen die an dem Blattstapelrücken angrenzenden Seitenbereiche des Blattstapels anpreßbar sind.The invention relates to a device for hanging adhesive-bound sheet stacks in envelopes, consisting of a pressing plate pressing the back area of the envelope against the back of the stack of sheets and of two folding jaws movable along the top of the pressing plate, with the aid of which the lateral projections of the envelope against those adjacent to the back of the stack of sheets Side areas of the sheet stack are pressed.

Bei den vorbekannten Einhängevorrichtungen werden zur Durchführung dieser Maßnahmen zwei voneinander unabhängige Antriebe verwendet. Die Preßplatte, deren Oberfläche sich bevorzugt in horizontaler Richtung erstreckt, braucht lediglich eine geringe Strecke vertikal auf- und abwärts bewegt zu werden, um den Umschlag gegen den Blattstapelrücken anzulegen und anzupressen. Anders verhält es sich bei den Falzbacken, denn deren Preßhub wird von einem wesentlich größeren Hub überlagert, der in Abhängigkeit von der Blattstapeldicke bemessen ist. Es ist daher bisher als unmöglich gehalten worden, die Preßplatte und die Preßbacken über ein- und denselben Antrieb zu bewegen, weil dadurch eine Anpassung an unterschiedlich dicke Blattstapel unmöglich gemacht wird.In the known suspension devices, two mutually independent drives are used to carry out these measures. The press plate, the surface of which preferably extends in the horizontal direction, only needs to be moved vertically up and down a short distance in order to place and press the envelope against the back of the stack of sheets. The situation is different for the folding jaws, because their press stroke is overlaid by a much larger stroke, which is dimensioned depending on the sheet stack thickness. It has therefore previously been considered impossible to move the press plate and the press jaws using one and the same drive, because this makes adaptation to sheet stacks of different thicknesses impossible.

Es ist zwar durch die DE-AS-1 536 499 - sie liegt dem Oberbegriff des Anspruchs zugrunde 1 bekannt, ein Fälzelband mit einer von einer Antriebswelle abgeleiteten Folgesteuerung zunächst gegen den Blattstapelrücken anzupressen und über Erwärmung anzuschmelzen, um daraufhin Fälzelbacken zum Verleimen der Fälzelüberstände an Seitenbereiche des Blattstapels zunächst auseinanderzubewegen und nach Durchführung einer Anhebebewegung der Preßplatte wieder gegeneinander zu bewegen. Wenn aber Blattstapel unterschiedlicher Dicke mit Fälzelbändern verklebt werden sollen, muß ein in Fig. 9 dieser Schrift gezeigtes zusätzliches Getriebe vorgesehen sein, um die Öffnungsweite der Fälzelbacken auf die Blattstapeldicke einzustellen.Although it is known from DE-AS-1 536 499 - it is based on the preamble of claim 1, first of all to press a folder with a sequence control derived from a drive shaft against the back of the stack of sheets and to melt it by heating, in order to then fold jaws for gluing the excess of the folder First move side areas of the sheet stack apart and move them against each other again after performing a lifting movement of the press plate. If, however, sheet stacks of different thicknesses are to be glued together with rebate strips, an additional gear shown in FIG. 9 of this document must be provided in order to adjust the opening width of the rebate jaws to the sheet pile thickness.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Klebebindevorrichtung für einen mit einem Umschlag zu versehenden Blattstapel so zu vereinfachen, daß die erforderlichen Bewegungen für das Anpressen und Verkleben des Umschlages mit dem Blattstapel (Einhängen) von einer einzigen Antriebsquelle abgeleitet werden können, ohne abhängig von der Blattstapeldicke sein zu müssenThe invention is based on the object of simplifying an adhesive binding device for a stack of sheets to be provided with an envelope so that the movements required for pressing and gluing the envelope to the stack of sheets (hanging) can be derived from a single drive source without being dependent on the sheet stack thickness

Diese Aufgabe ist neu.This task is new.

Sie wird erfindungsgemäß dadurch gelöst, daß die Preßplatte und die Falzbacken an schwenkbar gelagerten Haltegliedern angeordnet und die Halteglieder über ein gemeinsames Antriebsmittel mit einem einzigen Antriebsmotor verbunden sind, wobei zwischen dem Antriebsmittel und den mit einer Folgesteuerung bewegbaren Haltegliedern drehmomentabhängig einstellbare Schlupfglieder vorgesehen sind.It is achieved according to the invention in that the press plate and the folding jaws are arranged on pivotably mounted holding members and the holding members are connected to a single drive motor via a common drive means, slip elements which can be set as a function of torque being provided between the drive means and the holding members movable with a sequential control.

Als bevorzugte Ausführungsform für diese allgemeine Lehre wird erfindungsgemäß vorgesehen, daß als Antriebsmittel ein flexibles Zugelement, z. B. Kette, Riemen oder dgl., vorgesehen ist, dessen eines Ende an einem mit dem Antriebsmotor verbundenen Rad nach Art einer Winde befestigt ist und dessen anderes Ende mit einem der beiden Halteglieder für die Falzbacken verbunden ist, wobei das Zugelement über ein am anderen Halteglied für die Falzbacken gelagertes Umlenkrad und über ein auf der Schwenkachse des Haltegliedes für die Preßplatte angeordnetes Antriebsrad geführt ist.As a preferred embodiment for this general teaching, the invention provides that a flexible tension element, z. B. chain, belt or the like. Is provided, one end of which is attached to a wheel connected to the drive motor in the manner of a winch and the other end of which is connected to one of the two holding members for the jaws, the tension element being connected to one another Holding member for the jaws mounted deflection wheel and is guided over a drive wheel arranged on the pivot axis of the holding member for the press plate.

Mit dem Gegenstand der Erfindung wird erreicht, daß die fortlaufende Bewegung eines Antriebsmittel in einer Richtung dazu führt, daß nach und nach zunächst die Preßplatte gegen den Umschlagrücken und danach der Umschlagrücken gegen den Blattstapelrücken gepreßt und erst hiernach die Falzbacken gegen den Überstand des Umschlages und damit gegen die Seiten des Blattstapels angedrückt werden. Weil die Bewegung der einzelnen Teile nacheinander erfolgt, sind Schlupfglieder vorgesehen, welche die Steigerung des Anpreßdruckes im Rückenbereich des Blattstapels auf einen einstellbaren Wert begrenzen und damit eine Bewegung der nachfolgenden Falzbacken ohne Gefahr der Überlastung des Preßdruckes ermöglichen. Das gleiche Schlupfglied ist im Antriebszug vorgesehen, um den Antriebsmotor abzustellen, bevor die Falzbacken einen einstellbaren Grenzwert des Anpreßdruckes überschreiten.With the object of the invention it is achieved that the continuous movement of a drive means in one direction leads to the fact that gradually the press plate is first pressed against the back of the cover and then the back of the cover against the back of the stack of sheets and only then the jaws against the overhang of the cover and thus against the sides of the sheet stack. Because the movement of the individual parts takes place in succession, slip members are provided which limit the increase in the contact pressure in the back area of the sheet stack to an adjustable value and thus enable movement of the subsequent jaws without the risk of overloading the contact pressure. The same slip member is provided in the drive train to shut off the drive motor before the jaws exceed an adjustable limit of the contact pressure.

Die Erfindung ist allerdings nicht auf das bevorzugte Ausführungsbeispiel beschränkt, weil es durchaus möglich ist, die Bewegungen der einzelnen Halteglieder von einer gemeinsamen Antriebswelle aus abzunehmen, wobei durchaus auch jedem Halteglied ein eigener Antriebszug zugeordnet werden kann, vorausgesetzt, daß Schlupfglieder wie beim bevorzugten Ausführungsbeispiel Anwendung finden, die ein Weiterdrehen der Antriebswelle ermöglichen, ohne daß eine Überlastung des einen oder anderen Preßgliedes stattfindet.However, the invention is not limited to the preferred embodiment because it is entirely possible to take the movements of the individual holding members from a common drive shaft, and each holding member can also be assigned its own drive train, provided that slip members as in the preferred embodiment are used find that allow a further rotation of the drive shaft without an overload of one or the other pressing member takes place.

Wenn man aber im Sinne des bevorzugten Ausführungsbeispieles der Erfindung von einem flexiblen Zugelement ausgeht, dann erweist es sich als empfehlenswert, das Zugglied über ein an einem Schwenkarm gelagertes Umlenkrad zu führen und den Schwenkarn mit einem Schalter für den Antriebsmotor bei Überwindung einer einstellbaren Zugspannung zusammenwirken zu lassen. Diese Anordnung setzt in ihrer Wirkung ein, wenn der Umschlag mit seinem seitlichen Überstand in ausreichender Weise mit dem Blattstapel verpreßt und verklebt worden ist. Zugleich kann mit dieser Schalteranordnung auch eine Umkehr der Antriebsbewegung eingeleitet werden, um die einzelnen Elemente wieder in ihre Ausgangslage zurückzubewegen.If, however, in the sense of the preferred exemplary embodiment of the invention, a flexible tension element is used, then it proves to be advisable to guide the tension element over a deflection wheel mounted on a swivel arm and to cooperate the swivel arm with a switch for the drive motor when overcoming an adjustable tension to let. This arrangement takes effect when the envelope with its lateral projection has been sufficiently pressed and glued to the sheet stack. At the same time, a reversal of the drive movement can also be initiated with this switch arrangement in order to move the individual elements back into their starting position.

Weitere Einzelheiten für zweckmäßige Ausgestaltungen der Erfindung sind den Unteransprüchen 4 bis 8 sowie der Zeichnung und Beschreibung zu entnehmen. In der Zeichnung ist die Erfindung schematisch und beispielsweise dargestellt. Es zeigen:

  • Fig. 1: Eine schematische Seitenansicht einer Einhängevorrichtung und
  • Fig. 2: einen Vertikalschnitt entlang der Linie II - 11 durch eine Schwenkachse in Fig. 1.
Further details for expedient embodiments of the invention can be found in subclaims 4 to 8 and in the drawing and description. In the drawing, the invention is shown schematically and for example. Show it:
  • Fig. 1: A schematic side view of a suspension device and
  • 2: a vertical section along the line II - 11 through a pivot axis in Fig. 1st

Das Ausführungsbeispiel der Fig. 1 zeigt eine schematische Seitenansicht einer Einhängevorrichtung in einer Klebebindeanordnung. Unter Einhängen wird das Zusammenführen eines Blattstapels mit einem Umschlag, deren gegenseitiges Anpressen und deren Verleimung verstanden. Es ist dabei gleichgültig, wie die Blätter des Blattstapels 1 untereinander verbunden sind. Es wird allerdings empfohlen, die Blätter mittels flüssigen Klebstoffes im Sinne der der herkömmlichen Klebebindung oder mit Schmelzkleber zu behandeln, bevor sie in den Umschlag 2 eingehängt und verpreßt sowie verklebt werden. Es wird auch offengelassen, die Verbindung der Blätter untereinander sowie mit dem Umschlag 2 dadurch herbeizuführen, daß ein mit einem Heißschmelzkleber versehener Umschlag während des Anpressens gegen den Blattstapel 7 erhitzt und damit die Klebebindung der Blätter untereinander herbeigeführt wird. Schließlich schließt die Erfindung auch nicht aus, einen auf andere Weise gebundenen Blattstapel 1 in erfindungsgemäßer Weise mit einem Umschlag 2 zu verkleben.The embodiment of FIG. 1 shows a schematic side view of a hanging device in an adhesive binding arrangement. Hanging is understood to mean bringing together a stack of sheets with an envelope, pressing them against one another and gluing them together. It does not matter how the sheets of the sheet stack 1 are interconnected. However, it is recommended that the sheets be treated with liquid adhesive in the manner of conventional adhesive binding or with hot melt adhesive before they are hung into the envelope 2 and pressed and glued. It is also left open to bring about the connection of the sheets to one another and to the envelope 2 in that an envelope provided with a hot-melt adhesive is heated during the pressing against the sheet stack 7 and thus the adhesive binding of the sheets to one another is brought about. Finally, the invention also does not rule out gluing a sheet stack 1 bound in another way to an envelope 2 in the manner according to the invention.

Bei der modernen Fertigung von Broschüren wird man zweckmäßigerweise davon ausgehen, den Blattstapel 1 mit einem Heißschmelzkleber zubeschichten und an den so beschichteten Blattstapelrücken den Umschlag 2 unverzüglich anzudrücken, wobei längs der Kanten des Blattstapelrückens so viel Klebstoff vorhanden ist, daß dieser auch um diese Kanten fließen und zur seitlichen Anleimung des Umschlages führen kann.In the modern production of brochures, it will be expedient to assume that the stack of sheets 1 is coated with a hot-melt adhesive and that the cover 2 is immediately pressed onto the back of the stack of sheets coated in this way, there being so much adhesive along the edges of the back of the stack of sheets that it also flows around these edges and can lead to side gluing of the envelope.

Zur Verdeutlichung der Erfindung sei noch erwähnt, daß der Blattstapelrücken mit 3 und der Umschlagrücken mit 4 bezeichnet ist. Der Umschlag weist einen Überstand 5 auf, in dessen Bereich er durchaus auch mit den Seiten des Blattstapels 1 verklebt werden kann. Hierzu kann es dienlich sein, daß der Umschlag 2 vorgerillt oder vorgeritzt ist. Die Erfindung schließt aber auch nicht aus, einen unbehandelten Umschlag scharfkantig um den Rückenbereich des Blattstapels 1 zu verformen, zu verpressen und zu verleimen.To clarify the invention, it should also be mentioned that the sheet stack spine is designated 3 and the cover spine 4. The envelope has a projection 5, in the area of which it can also be glued to the sides of the sheet stack 1. It may be useful for this purpose that the envelope 2 is pre-grooved or pre-scored. However, the invention also does not rule out deforming, compressing and gluing an untreated envelope with sharp edges around the back area of the sheet stack 1.

Der Blattstapel 1 ist in der Arbeitsstellung durch angedeutete Klemmbacken 6 festgehalten. Es empfiehlt sich, den Blattstapel 1 gegebenenfalls mit dem Umschlag 2 längs der Längsachse des Blattstapelrückens 3 in die Einhängevorrichtung einzuführen. Eine solche Methode ist bekannt und bedarf daher nicht der näheren Erläuterung. Der Umschlag 2 kann hingegen auch für sich in die Einhängestation zentriert eingeführt werden.The sheet stack 1 is held in the working position by indicated jaws 6. It is advisable to insert the sheet stack 1 into the hanging device along with the envelope 2 along the longitudinal axis of the sheet stack back 3. Such a method is known and therefore does not require further explanation. The envelope 2, on the other hand, can also be inserted centered into the hanging station.

Die Fig. 1 zeigt nun eine Einhängevorrichtung nach dem bevorzugten Ausführungsbeispiel der Erfindung, ohne daß die Erfindung darauf beschränkt ist. Danach sind eine Preßplatte 7 und zwei Falzbacken 8, 9 an schwenkbar gelagerten Haltegliedern 10, 11, 12 angeordnet. Die Schwenkachsen 14, 15, 16 dieser Halteglieder 10, 11, 12 sind zueinander parallel sowie auch parallel zur Längsachse des Blattstapelrückens 3 angeordnet. In der Zeichnung gemäß Fig. 1 ist die Preßplatte 7 in ihrer Wirkstellung gezeigt, in der sie den Umschlagrücken 4 gegen den Blattstapelrücken 3 andrückt. Gestrichelt ist die Lage dieser Preßplatte 7 gezeigt, wenn sie sich in ihrer Ruhestellung bzw. Ausgangslage befindet.Fig. 1 now shows a suspension device according to the preferred embodiment of the invention, without the invention being limited thereto. Thereafter, a press plate 7 and two jaws 8, 9 are arranged on pivotally mounted holding members 10, 11, 12. The pivot axes 14, 15, 16 of these holding members 10, 11, 12 are arranged parallel to one another and also parallel to the longitudinal axis of the sheet stack back 3. 1, the press plate 7 is shown in its operative position, in which it presses the back cover 4 against the sheet stack back 3. The position of this press plate 7 is shown in broken lines when it is in its rest position or starting position.

Das Halteglied 10 für die Preßplatte 7 ist an einer Hohlwelle 13 angeordnet, welche um die Achse 14 verschwenkbar ist.The holding member 10 for the press plate 7 is arranged on a hollow shaft 13 which is pivotable about the axis 14.

Die Falzbacken 8, 9 sind hingegen an hebelartigen Haltegliedern 11, 12 angeordnet, welche um die Achsen 15,16 schwenkbar sind. In ihrer Grundstellung sind diese Halteglieder 11,12 durch eine Feder 35 gehalten, welche beim Beispiel der Fig. 1 als Druckfeder ausgebildet ist und daher die Falzbacken 8, 9 voneinander wegbewegt. Diese Falzbacken 8, 9 werden längs der Oberfläche der Preßplatte 7 in Richtung zum Blattstapel 1 und entgegengesetzt hierzu bewegt. Da die Halteglieder 11, 12 schwenkbar gelagerte Elemente sind, empfiehlt es sich, die Falzbacken 8, 9 über Gelenke 17, 18 an den Haltegliedern 11, 12 anzuordnen. Da das Halteglied 12 eine größere Distanz vom Blattstapel 1 besitzt als das Halteglied 11, ist ein Ansatz 19 am Halteglied 12 vorgesehen, welcher seinerseits das Gelenk 18 trägt. Über diese Gelenke 17, 18 wird eine geradlinige Bewegung der Falzbacken 8, 9 herbeigeführt, obwohl die Halteglieder 11, 12 um die Achsen 15, 16 schwenken.The folding jaws 8, 9, on the other hand, are arranged on lever-like holding members 11, 12 which can be pivoted about the axes 15, 16. In their basic position, these holding members 11, 12 are held by a spring 35, which in the example of FIG. 1 is designed as a compression spring and therefore moves the jaws 8, 9 away from one another. These jaws 8, 9 are moved along the surface of the press plate 7 in the direction of the sheet stack 1 and opposite thereto. Since the holding members 11, 12 are pivotally mounted elements, it is advisable to arrange the folding jaws 8, 9 on the holding members 11, 12 via joints 17, 18. Since the holding member 12 is at a greater distance from the sheet stack 1 than the holding member 11, an extension 19 is provided on the holding member 12, which in turn carries the joint 18. A straight movement of the jaws 8, 9 is brought about via these joints 17, 18, although the holding members 11, 12 pivot about the axes 15, 16.

Erfindungsgemäß wird davon ausgegangen, daß die bisher geschilderte Anordnung über einen einzigen Antriebsmotor 21 bewegbar ist. Zu diesem Zweck ist beim bevorzugten Ausführungsbeispiel ein flexibles Zugglied 20 vorgesehen, das windenartig an einem Rad 22 am Antriebsmotor 21 befestigt ist. Dieses flexible Zugglied 20 führt vom Motor 21 aus über ein Umlenkrad 26 zu einem Antriebsrad 23, das auf der Achse 14 angeordnet ist. Durch Verdrehung dieses Antriebsrades 23 wird das Halteglied 10 der Preßplatte 7 um die Achse 14 verschwenkt.According to the invention, it is assumed that the arrangement described so far can be moved via a single drive motor 21. For this purpose, in the preferred embodiment, a flexible tension member 20 is provided, which is attached to a wheel 22 on the drive motor 21 in a winch-like manner. This flexible tension member 20 leads from the motor 21 via a deflection wheel 26 to a drive wheel 23 which is arranged on the axis 14. By turning this drive wheel 23, the holding member 10 of the press plate 7 is pivoted about the axis 14.

Von diesem Antriebsrad 13 führt das flexible Zugglied 20 zu einem Umlenkrad 24, das am Halteglied 12 drehbar gelagert ist. Das Ende 25 des Zuggliedes 20 ist an wählbarer Stelle am Halteglied 11 befestigt. Eine Bewegung des flexiblen Zuggliedes 20 in Pfeilrichtung führt also einerseits zum Heranschwenken der Preßplatte 7 an den Blattstapel- bzw. Umschlagrücken 3, 4 und andererseits zum Gegeneinanderbewegen der Falzbacken 8, 9 gegen den Überstand 5 des Umschlages 2. Dabei werden die beiden Halteglieder 11, 12 gegen die Wirkung der Feder 35 einander genähert.From this drive wheel 13, the flexible tension member 20 leads to a deflection wheel 24 which is rotatably mounted on the holding member 12. The end 25 of the tension member 20 is attached to the holding member 11 at a selectable location. Movement of the flexible tension member 20 in the direction of the arrow thus leads, on the one hand, to the swiveling of the pressure plate 7 against the sheet stack or cover spines 3, 4 and, on the other hand, to the folding jaws 8, 9 moving against one another against the overhang 5 of the cover 2. The two holding members 11, 12 against the action of the spring 35 approached each other.

Damit nun aber die Drehbewegung des Antriebsmotores 21 keine Überbelastung am Blattstapel 1 herbeiführt, sind Schlupfglieder in den Antrieb eingebaut, deren Wirkung und Anordnung sich aus Fig. 2 ergibt. Entsprechend dem Schnitt 11 - II durch die Achse 14 der Fig. 1 erkennt man eine zwischen zwei Gestellwänden 31 eingespannte Achse 32, auf der die Hohlwelle 13 gelagert ist, welche gemäß Fig. 1 mit dem Halteglied 10 verbunden ist. Auf dieser Achse 32 ist aber auch das Antriebsrad 23 über eine Schlupfkupplung 33 gelagert. Die Verdrehung des Antriebsrades 23 über das flexible Zugglied 20 führt also so lange zur Drehbewegung der Hohlwelle 13, bis das einstellbare Schlupfmoment an der Schlupfkupplung 33 erreicht bzw. überschritten wird. Dies ist dann der Fall, wenn die Preßplatte 7 mit einem ausreichenden Preßdruck am Blattstapelrücken 3 anliegt. Sobald dieser Zustand erreicht ist, dreht das Antriebsrad 23 unter Schlupfwirkung weiter, wohingegen die Hohlwelle 13 stehen bleibt. Die Drehbewegung des Antriebsrades 23 führt über das flexible Zugglied 20 zu einer gegeneinandergerichteten Schwenkbewegung der Halteglieder 11, 12 und daher zur Einwirkung der Falzbacken 8, 9 auf den Überstand 5 des Umschlages 2.So that the rotary movement of the drive motor 21 does not cause an overload on the sheet stack 1, slip members are installed in the drive, the effect and arrangement of which can be seen in FIG. 2. According to the section 11 - II through the axis 14 of FIG. 1, one can see an axis 32 clamped between two frame walls 31, on which the hollow shaft 13 is mounted, which is connected to the holding member 10 according to FIG. 1. However, the drive wheel 23 is also mounted on this axle 32 via a slip clutch 33. The rotation of the drive wheel 23 via the flexible tension member 20 thus leads to the rotary movement of the hollow shaft 13 until the adjustable slip torque at the slip clutch 33 is reached or exceeded. This is the case when the pressure plate 7 is in contact with the back of the sheet stack 3 with sufficient pressure. As soon as this state is reached, the drive wheel 23 continues to rotate under the effect of slippage, whereas the hollow shaft 13 stops. The rotational movement of the drive wheel 23 leads via the flexible tension member 20 to a counter-rotating movement of the holding members 11, 12 and therefore to the action of the jaws 8, 9 on the projection 5 of the envelope 2.

Wenn aber die Falzbacken 8, 9 mit dem erforderlichen Preßdruck an den Seiten des Blattstapels 1 anliegen, wird durch die Erhöhung der Zugspannung im flexiblen Zugglied 20 das Umlenkrad 26 gegen die Wirkung der Feder 30 verstellt, was zu einer Schwenkbewegung des Schwenkarmes 27 um die Schwenkachse 28 führt. Diese Schwenkbewegung betätigt einen Schalter 29, der den Antriebsmotor 21 abschaltet und in der Drehrichtung umschaltet, gegebenenfalls unter Einbeziehung eines Zeitfaktors, um die Falzbacken 8, 9 und die Preßplatte 7 über einen gewissen Zeitbereich in Preßstellung zu halten.But if the jaws 8, 9 rest with the required pressure on the sides of the sheet stack 1, the deflection wheel 26 is adjusted against the action of the spring 30 by increasing the tension in the flexible tension member 20, resulting in a pivoting movement of the pivot arm 27 about the pivot axis 28 leads. This pivoting movement actuates a switch 29 which switches off the drive motor 21 and switches over in the direction of rotation, possibly with the inclusion of a time factor, in order to keep the jaws 8, 9 and the press plate 7 in the press position over a certain time range.

Bei der Umschaltung der Drehrichtung des Antriebsmotores 21 kommt die Feder 35 zwischen den Haltegliedern 11, 12 zur Wirkung. Da aber das Halteglied 10 für die Preßplatte 7 schon vorzeitig in ihre gestrichelt dargestellte Endlage gelangt ist, sind die Freiläufe 34 gemäß Fig. 2 vorgesehen, welche es ermöglichen, die Halteglieder 11, 12 unter der Wirkung der Feder 35 in ihre Ausgangsstellung zurückzubewegen.When switching the direction of rotation of the drive motor 21, the spring 35 between the holding members 11, 12 comes into effect. However, since the holding member 10 for the pressing plate 7 has already reached its end position shown in dashed lines, the freewheels 34 according to FIG. 2 are provided, which make it possible to move the holding members 11, 12 back into their starting position under the action of the spring 35.

Die Funktion des Erfindungsgegenstandes ist folgende:The function of the object of the invention is as follows:

In der Ausgangslage befindet sich die Preßplatte 7 mit ihrem Halteglied 10 in der in Fig. 1 gezeigten, gestrichelten Lage. Der Blattstapel 1 wird über die Klemmbacken 6 in die Einhängestellung bewegt, was bevorzugt längs der Längsachse des Blattstapelrückens 3 erfolgt. Der Umschlag 2 kann vorher in die Einhängestation eingelegt worden sein. Er kann aber auch zusammen mit dem Blattstapel 1 in die Einhängestation bewegt werden.In the starting position, the press plate 7 with its holding member 10 is in the dashed position shown in FIG. 1. The sheet stack 1 is moved into the hanging position via the clamping jaws 6, which is preferably carried out along the longitudinal axis of the sheet stack back 3. The envelope 2 may previously have been inserted into the hanging station. However, it can also be moved together with the sheet stack 1 into the hanging station.

Durch Einschaltung des Antriebsmotores 21 wird das flexible Zugglied 20 in Pfeilrichtung bewegt. Diese Bewegung führt zunächst dazu, daß die Hohlwelle 13 mit dem Halteglied 10 und die Achse 14 im Gegenuhrzeigersinn verschwenkt wird, was zur Anlage der Preßplatte 7 am Umschlagrücken 4 und schließlich am Blattstapelrücken 3 führt. Sobald dort ein einstellbarer Anpreßdruck erreicht wird, beginnt die Schlupfkupplung 33 (Fig. 2) zu reagieren, so daß das Antriebsrad 23 rotieren kann, ohne die Hohlwelle 13 noch weiter zu verdrehen. In dieser Bewegungsphase werden die Halteglieder 11, 12 über das flexible Zugglied 20 gegeneinander bewegt, und zwar gegen die Wirkung der Feder 35. Dies führt zur Anlage der Falzbacken 8, 9 am Überstand 5 des Umschlages 2 und zur Verklebung dieses Überstandes 5 an den Seiten des Blattstapels 1. Sobald hier der entsprechende Anpreßdruck erreicht bzw. überschritten wird, erfolgt durch die Zugspannung im flexiblen Zugglied 20 eine Anhebebewegung am Umlenkrad 26, welche den Schwenkarm 27 gegen die Wirkung der Feder 30 dem Schalter 29 nähert. Sobald dieser betätigt ist, wird der Antriebsmotor 21 abgeschaltet und - gegebenenfalls nach einer einstellbaren Zeit - in die Gegenantriebsrichtung umgestellt. Sobald die Zugspannung des Antriebsmotores 21 vom flexiblen Zugglied 20 genommen ist, verursacht die gespannte Feder 35 ein Auseinanderbewegen der Halteglieder 11,12, was zu einer rückläufigen Bewegung des Haltegliedes 10 mit der Preßplatte 7 führt. Sobald diese in der gestrichelt gezeigten Stellung an einem Anschlag angelangt ist, wobei aber die Halteglieder 11, 12 noch nicht ihre Endstellung erreicht haben, wird deren Bewegung zufolge der Freiläufe 34 trotz Stillstandes des Haltegliedes 10 ermöglicht.By switching on the drive motor 21, the flexible tension member 20 is moved in the direction of the arrow. This movement leads to the fact that the hollow shaft 13 is pivoted with the holding member 10 and the axis 14 in the counterclockwise direction, which leads to the pressing of the press plate 7 on the back cover 4 and finally on the sheet stack back 3. As soon as an adjustable contact pressure is reached, the slip clutch 33 (FIG. 2) begins to react, so that the drive wheel 23 can rotate without rotating the hollow shaft 13 even further. In this phase of movement, the holding members 11, 12 are moved against each other via the flexible tension member 20, specifically against the action of the spring 35. This leads to the folding jaws 8, 9 resting on the overhang 5 of the envelope 2 and this overhang 5 being glued to the sides of the sheet stack 1. As soon as the corresponding contact pressure is reached or exceeded here, the tensile stress in the flexible tension member 20 causes a lifting movement on the deflection wheel 26, which approaches the swivel arm 27 against the action of the spring 30, the switch 29. As soon as this is actuated, the drive motor 21 is switched off and - if necessary after an adjustable time - switched to the counter-drive direction. As soon as the tension of the drive motor 21 is removed from the flexible tension member 20, the tensioned spring 35 causes the holding members 11, 12 to move apart, which leads to a backward movement of the holding member 10 with the press plate 7. As soon as this has reached a stop in the position shown in dashed lines, but the holding members 11, 12 have not yet reached their end position, their movement is made possible in spite of the holding member 10 being stationary, due to the freewheels 34.
