Abstract

The printed products (33) to be pressed run in an imbricated formation (S), in which the folding edges (33a) of the printed products (33) are on top, through between the press rollers (3, 4, 5, 6) of two pairs of press rollers (1, 2) arranged in succession. The upper press rollers (3, 5) of each pair of press rollers (1, 2), which come into contact directly with the folding edges (33a), are fixedly mounted. Opposite these, the other press rollers (4, 6) of each pair of press rollers (1, 2) are mounted on each side in a common mounting (15) supported flexibly on pneumatic springs (16). The press rollers (3, 4, 5, 6) are driven individually via elastic drive belts (17, 18, 19, 20). As a result of these measures, the printed products (33) can be pressed perfectly and with care, even at a high conveying speed. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Pressen von gefalteten Druckereierzeugnissen, wie Zeitungen, Zeitschriften und Teilen hievon gemäss Oberbegriff des Anspruches 1.The present invention relates to a device for pressing folded printed products, such as newspapers, magazines and parts thereof, according to the preamble of claim 1.

Derartige Pressvorrichtungen dienen dazu, gefaltete, mehrblättrige Druckereierzeugnisse im Bereich ihres Falzes zu verdichten und die zwischen den Blättern gefangene Luft herauszudrücken.Such pressing devices are used to compress folded, multi-sheet printed products in the area of their fold and to push out the air trapped between the sheets.

Aus der US-A-3,257,110 ist eine solche Pressvorrichtung bekannt, bei der die eine der Pressrollen des Pressrollenpaares in schwenkbar gelagerten Armen drehbar gelagert ist und mittels an diesen Armen angreifenden Zugfedern gegen die ortsfest gelagerte, andere Pressrolle des Pressrollenpaares gezogen wird.Such a press device is known from US-A-3,257,110, in which one of the press rolls of the press roll pair is rotatably mounted in pivotally mounted arms and is pulled by means of tension springs acting on these arms against the stationary, mounted other press roll of the press roll pair.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Pressvorrichtung der eingangs genannten Art zu schaffen, die bei platzsparender Bauweise auch bei hoher Fördergeschwindigkeit der Druckereierzeugnisse letztere im Falzbereich sehr stark und bleibend zusammenzupressen vermag, ohne dass dabei die Druckereierzeugnisse beschädigt werden.The present invention has for its object to provide a press device of the type mentioned which, with space-saving construction even with high conveying speed of the printed products, is able to compress the printed products very strongly and permanently in the fold area without the printed products being damaged in the process.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved according to the invention by the features of the characterizing part of claim 1.

Da die Druckereierzeugnisse mit ihren vorlaufenden Falzkanten den ortsfest gelagerten Pressrollen zugekehrt sind, erfolgt eine besonders wirkungsvolle Pressung im Falzbereich, da die direkt auf die Falzkanten einwirkenden Pressrollen nicht zurückgedrängt werden können. Diese wirkungsvolle, produkteschonende Pressung wird noch dadurch unterstützt, dass die Pressrollen einzeln angetrieben sind.Since the printed products with their leading fold edges face the stationary press rolls, there is a particularly effective pressing in the fold area, since the press rolls acting directly on the fold edges cannot be pushed back. This effective, product-friendly pressing is supported by the fact that the press rollers are individually driven.

Der Falzbereich wird durch die starke Pressung bleibend geformt, so dass später keine Zurückbildung des Falzes auftritt, was für die nachfolgende Weiterverarbeitung von grossem Vorteil ist.The fold area is permanently shaped by the strong pressure, so that the fold does not regress later, which is of great advantage for the subsequent further processing.

Aus der EP-A-0 417 621 und der entsprechenden US-A-5,125,330 ist eine Pressvorrichtung für Druckereierzeugnisse bekannt, bei der die Erzeugnisse ebenfalls zwei hintereinander angeordnete Rollenpaare mit je einer ortsfest gelagerten und einer rückfedernd gelagerten Rolle durchlaufen. Von diesen beiden Rollenpaaren dient jedoch nur das eine Rollenpaar zur eigentlichen Produktepressung, während das andere Rollenpaar durch Führungsrollen gebildet wird. Letztere sind nicht zwingend notwendig, da sie wie erwähnt nur zur Führung der mittels des ersten Rollenpaares gepressten Erzeugnisse dienen. Bei dieser bekannten Vorrichtung ist auch vorgesehen, die Produkte so in einer Schuppenformation durch die Press- und Führungsrollen hindurchzuführen, dass die Falzkante mit den ortsfest gelagerten Rollen in Berührung kommt. Diese Pressvorrichtung ist aber für einen andern Zweck ausgelegt, dient sie doch zum Pressen von Druckereierzeugnissen, die mit einer Ecke voraus die Rollenpaare durchlaufen, d.h. also mit ihrer Falzkante gegenüber der Förderrichtung schräggestellt.From EP-A-0 417 621 and the corresponding US-A-5,125,330 a press device for printed products is known, in which the products also pass through two pairs of rollers arranged one behind the other, each with a stationary and a spring-mounted roller. Of these two pairs of rollers, however, only one pair of rollers is used for actual product pressing, while the other pair of rollers is formed by guide rollers. The latter are not absolutely necessary since, as mentioned, they only serve to guide the products pressed by means of the first pair of rollers. In this known device it is also provided that the products are passed through the press and guide rollers in a scale formation in such a way that the fold edge comes into contact with the stationary rollers. This press device is designed for another purpose, however, since it is used for pressing printed products that pass through the roller pairs with a corner ahead, that is to say with their folded edge inclined relative to the conveying direction.

Anhand der vereinfachten Darstellung der Fig. 1 wird nachfolgend der grundsätzliche Aufbau der Pressvorrichtung erläutert. Der genauere Aufbau der Pressvorrichtung wird später anhand der Figuren 2-6 beschrieben werden.The basic structure of the pressing device is explained below on the basis of the simplified illustration in FIG. 1. The more precise structure of the pressing device will be described later with reference to FIGS. 2-6.

Die Pressvorrichtung weist ein erstes Pressrollenpaar 1 sowie ein diesem benachbart angeordnetes zweites Pressrollenpaar 2 auf. Die beiden zylindrischen Pressrollen jedes Pressrollenpaares 1 bzw. 2 sind mit 3 und 4 bzw. 5 und 6 bezeichnet. Die Pressrollen 3 und 4 bzw. 5 und 6 jedes Pressrollenpaares 1 bzw. 2 legen zwischen sich einen Durchgangsspalt 7 bzw. 8 fest. Die Pressrollen 3, 4, 5, 6 sind drehbar auf Achsen 9, 10, 11 bzw. 12 gelagert. Dabei sind die Achsen 9 und 11 der beiden obern Pressrollen 3 und 5 ortsfest in Lagerteilen gehalten, die in Fig. 1 nur schematisch dargestellt und mit 13 und 14 bezeichnet sind. Demgegenüber sind die Achsen 10 und 12 der beiden untern Rollen 4 und 6 in einer in Fig. 1 nur schematisch dargestellten gemeinsamen Lagerung 15 gelagert, die auf Luftfedern 16 abgestützt ist. Die Lagerung 15 und damit die Pressrollen 4 und 6 sind somit in Richtung des Pfeiles B verschiebbar federnd auf den Luftfedern 16 abgestützt, wie das später noch näher beschrieben werden wird.The press device has a first pair of press rollers 1 and a second pair of press rollers 2 arranged adjacent to it. The two cylindrical press rollers of each pair of press rollers 1 and 2 are denoted by 3 and 4 or 5 and 6. The press rollers 3 and 4 or 5 and 6 of each pair of press rollers 1 and 2 define a passage gap 7 and 8 between them. The press rollers 3, 4, 5, 6 are rotatably mounted on axes 9, 10, 11 and 12 respectively. The axes 9 and 11 of the two upper press rollers 3 and 5 are held stationary in bearing parts, which are shown only schematically in FIG. 1 and are designated by 13 and 14. In contrast, the axes 10 and 12 of the two lower rollers 4 and 6 are mounted in a common bearing 15, only schematically shown in FIG. 1, which is supported on air springs 16. The bearing 15 and thus the press rollers 4 and 6 are thus supported in the direction of arrow B so as to be resilient on the air springs 16, as will be described in more detail later.

Die Pressrollen 3, 4, 5, 6 sind einzeln mittels endloser Antriebsriemen 17, 18, 19 bzw. 20 aus einem elastisch dehnbaren Material, z.B. Gummi, angetrieben. Diese Antriebsriemen 17, 18, 19, 20 laufen in Rillen in der zugeordneten Pressrolle 3, 4, 5, 6 über diese Presswalzen 3, 4, 5, 6 sowie über Antriebswalzen 21, 22, 23 bzw. 24, die auf ortsfest, jedoch drehbar gelagerten Achsen 25, 26, 27 bzw. 28 befestigt sind. Die Antriebsanordnung zum Antreiben der Antriebswalzen 21, 22, 23 und 24 wird anhand der Fig. 2 noch näher erläutert werden. Dank ihrer elastischen Dehnbarkeit sind die Antriebsriemen 17, 18, 19, 20 in der Lage, Schwankungen der Umfangsgeschwindigkeit der Pressrollen 3, 4, 5, 6 auszugleichen. Solche Geschwindigkeitsschwankungen werden z.B. durch Unterschiede in der Dicke der durch die Durchgangsspalte 7, 8 hindurchlaufenden Schuppenformation hervorgerufen.The press rollers 3, 4, 5, 6 are individually driven by means of endless drive belts 17, 18, 19 and 20 made of an elastically stretchable material, for example rubber. These drive belts 17, 18, 19, 20 run in grooves in the associated press roll 3, 4, 5, 6 over these press rolls 3, 4, 5, 6 and over drive rolls 21, 22, 23 and 24, respectively, which are stationary, however rotatably mounted axes 25, 26, 27 and 28 are attached. The drive arrangement for driving the drive rollers 21, 22, 23 and 24 will be explained in more detail with reference to FIG. 2. Thanks to their elastic extensibility, the drive belts 17, 18, 19, 20 are able to compensate for fluctuations in the peripheral speed of the press rollers 3, 4, 5, 6. Such speed fluctuations are caused, for example, by differences in the thickness of the scale formation passing through the passage gaps 7, 8.

Ueber die Antriebsrollen 21 und 23 einerseits und die Antriebsrollen 22 und 24 andererseits sind zudem endlose, elastische Führungselemente 29, 30 geführt, die weiter über die Pressrollen 3 und 5 bzw. 4 und 6 laufen. In Fig. 1 sind diese Führungselemente 29, 30 nur teilweise sichtbar, nämlich nur die Abschnitte 29a, 29b bzw. 30a, 30b, welche den Zwischenraum 31 bzw. 32 zwischen den Pressrollen 3 und 5 bzw. 4 und 6 überspannen und abdecken. Die Anordnung der Antriebsriemen 17, 18, 19, 20 und der Führungselemente 29, 30 ist aus Fig. 3 ersichtlich.Endless, elastic guide elements 29, 30 are also guided over the drive rollers 21 and 23 on the one hand and the drive rollers 22 and 24 on the other hand, which run further over the press rollers 3 and 5 or 4 and 6. In Fig. 1, these guide elements 29, 30 are only partially visible, namely only the sections 29a, 29b and 30a, 30b, which span and cover the space 31 and 32 between the press rollers 3 and 5 or 4 and 6. The arrangement of the drive belts 17, 18, 19, 20 and the guide elements 29, 30 can be seen in FIG. 3.

In Fig. 1 ist weiter ein Teil einer Schuppenformation S bestehend aus dachziegelartig übereinanderliegenden Druckereierzeugnissen 33 gezeigt. Dabei liegt jedes Druckereierzeugnis 33 auf dem vorauslaufenden Druckereierzeugnis auf, so dass die vorauslaufende Falzkante 33a jedes Druckereierzeugnisses 33 auf der Oberseite der Schuppenformation S liegt. Ein der Zuführung der Schuppenformation S dienender Zuförderer 34 ist nur ganz schematisch angedeutet.1 also shows part of a scale formation S consisting of printed products 33 lying one above the other in the manner of roof tiles. Each printed product 33 lies on the leading printed product, so that the leading fold edge 33a of each printed product 33 lies on the top of the scale formation S. A feed conveyor 34 serving to feed the scale formation S is only indicated very schematically.

Die Druckereierzeugnisse 33 durchlaufen die Durchgangsspalte 7, 8 der Rollenpaare 1 und 2 und werden dabei zusammengepresst.The printed products 33 pass through the passage gaps 7, 8 of the roller pairs 1 and 2 and are thereby pressed together.

Anhand der Figuren 2 bis 6 wird nun der vollständige Aufbau der Pressvorrichtung erläutert.The complete structure of the pressing device will now be explained with reference to FIGS. 2 to 6.

In Fig. 2 ist die gesamte Pressvorrichtung in Seitenansicht gezeigt. Die anhand der Fig. 1 bereits erläuterten Bauteile sind auch in dieser Fig. 2 sichtbar, doch sind zur Wahrung der besseren Uebersichtlichkeit nicht alle dieser Bauteile mit den zugeordneten Bezugszeichen versehen. Anhand der Fig. 2 zusammen mit der Fig. 3 wird vor allem das Antriebssystem für die Presswalzen 3, 4, 5, 6 erläutert. In der Grundrissfigur 3 ist nur die Hälfte der Vorrichtung gezeigt, wobei noch gewisse Teile weggelassen bzw. weggeschnitten sind.In Fig. 2, the entire press device is shown in side view. The components already explained with reference to FIG. 1 are also visible in this FIG. 2, but not all of these components are provided with the assigned reference numerals in order to maintain clarity. The drive system for the press rolls 3, 4, 5, 6 is explained above with reference to FIG. 2 together with FIG. 3. In floor plan figure 3 is only half of the device shown, with certain parts omitted or cut away.

Die anhand der Fig. 1 erläuterten Bauteile sind in einem Gestell 35 angeordnet bzw. gelagert. In diesem Gestell befindet sich auch ein nur schematisch dargestellter Antrieb 36, der über einen endlosen, beidseitig mit einer Zahnung versehenen Zahnriemen 37 die Antriebswalzen 21, 22, 23 und 24 antreibt. Der Zahnriemen 37 ist über ein Zahnrad 38 geführt, das auf der Achse 28 sitzt, die vom Antrieb 36 angetrieben ist und mit der drehfest die Antriebswalze 24 verbunden ist (Fig. 3). Wie aus Fig. 2 hervorgeht, dreht das Zahnrad 38 im Uhrzeigersinn und der Zahnriemen 37 bewegt sich in Richtung des Pfeiles C. Vom Zahnrad 38 läuft der Zahnriemen über Umlenkrollen 39, 40 und 41 zu einem Zahnrad 42 (Fig. 3), welches auf der Achse 26 sitzt, mit der die Antriebswalze 22 verbunden ist. Von diesem Zahnrad 42 wird der Zahnriemen 37 über ein Zahnrad 43 (Fig. 2) geführt, das mit der in Fig. 3 nicht gezeigten Antriebswalze 21 drehfest verbunden ist. Von diesem Zahnrad 43 läuft der Zahnriemen 37 über Umlenkräder 44, 45, 46 und 47 zu einem Zahnrad 48 (siehe Fig. 3) und von diesem zum bereits erwähnten Zahnrad 38. Dieses Zahnrad 48 sitzt auf der Achse 27, mit der die Antriebswalze 23 drehfest verbunden ist.The components explained with reference to FIG. 1 are arranged or stored in a frame 35. In this frame there is also a drive 36, shown only schematically, which drives the drive rollers 21, 22, 23 and 24 via an endless toothed belt 37 provided with teeth on both sides. The toothed belt 37 is guided over a toothed wheel 38, which is seated on the axis 28, which is driven by the drive 36 and to which the drive roller 24 is connected in a rotationally fixed manner (FIG. 3). 2, the gear 38 rotates clockwise and the toothed belt 37 moves in the direction of arrow C. From the gear 38, the toothed belt runs over deflection rollers 39, 40 and 41 to a gear 42 (FIG. 3), which opens the axis 26 sits, with which the drive roller 22 is connected. The toothed belt 37 is guided by this toothed wheel 42 via a toothed wheel 43 (FIG. 2) which is connected in a rotationally fixed manner to the drive roller 21, which is not shown in FIG. 3. The toothed belt 37 runs from this toothed wheel 43 via deflection wheels 44, 45, 46 and 47 to a toothed wheel 48 (see FIG. 3) and from there to the toothed wheel 38 already mentioned. This toothed wheel 48 is seated on the axis 27 with which the drive roller 23 is rotatably connected.

Wie aus Fig. 2 weiter ersichtlich, sind die Luftfedern 16 über eine Druckleitung 49 mit einer Druckregeleinheit 50 verbunden, welche an einen Druckluftanschluss 51 angeschlossen ist. Mittels der Druckregeleinheit 50 wird der Druck im Innern der Luftfedern 16, und damit auch die von den Druckfedern 16 ausgeübte Kraft auf jeweils bestimmte Werte eingestellt.As can also be seen from FIG. 2, the air springs 16 are connected via a pressure line 49 to a pressure control unit 50 which is connected to a compressed air connection 51. The pressure control unit 50 is used to set the pressure inside the air springs 16, and thus also the force exerted by the pressure springs 16, to specific values.

Aus der Fig. 3 ist wie erwähnt die Anordnung der Antriebsriemen 17, 18, 19, 20 der Führungselemente 29 und 30 gezeigt, wobei diese Antriebsriemen und Führungselemente teilweise geschnitten dargestellt sind. Wie aus Fig. 3 hervorgeht sind die Antriebsriemen 17, 18, 19, 20 seitlich der Pressrollen 3, 4, 5, 6 angeordnet, während die Führungselemente 29, 30 über die Länge der Pressrollen 3, 4, 5, 6 verteilt und gegeneinander versetzt angeordnet sind.3, as mentioned, the arrangement of the drive belts 17, 18, 19, 20 of the guide elements 29 and 30 is shown, these drive belts and guide elements being shown partly in section. As can be seen from FIG. 3, the drive belts 17, 18, 19, 20 are arranged to the side of the press rollers 3, 4, 5, 6, while the guide elements 29, 30 are distributed over the length of the press rollers 3, 4, 5, 6 and offset from one another are arranged.

Wie insbesondere Fig. 1 erkennen lässt dienen die Führungselemente 29, 30 dazu, die zugeführten Druckereierzeugnisse 33 in den Durchgangsspalt des ersten Pressrollenpaares 1 zu führen und den Zwischenraum 31, 32 zwischen den Pressrollen 3 und 5 sowie 4 und 6 abzudecken, damit die Druckereierzeugnisse 33 nicht in diesen Zwischenraum 31, 32 eindringen können, sondern zum Durchgangsspalt 8 des zweiten Pressrollenpaares 2 gelangen. Damit kommen die Führungselemente 29, 30 in Berührung mit den Druckereierzeugnissen 33. Ist die gezeigte Pressvorrichtung in unmittelbarer Nähe des Ausganges einer Rotationsdruckmaschine angeordnet, so besteht deshalb die Gefahr des Verschmierens der noch nicht ganz trockenen Druckfarbe. Um dies zu vermeiden, sind die Führungselemente 29, 30 aus einem dünnen, schraubenförmig gewickelten Draht 52 hergestellt, wie das in Fig. 4 gezeigt ist. Die Führungselemente 29, 30 sind somit wie lange und dünne Schraubenfedern ausgebildet.As can be seen in particular in FIG. 1, the guide elements 29, 30 serve to guide the supplied printed products 33 into the passage gap of the first press roller pair 1 and to cover the intermediate space 31, 32 between the press rollers 3 and 5 and 4 and 6, so that the printed products 33 cannot penetrate into this intermediate space 31, 32, but reach the passage gap 8 of the second pair of press rollers 2. The guide elements 29, 30 thus come into contact with the printed products 33. If the press device shown is arranged in the immediate vicinity of the outlet of a rotary printing press, there is therefore a risk of the printing ink not yet completely dry being smeared. In order to avoid this, the guide elements 29, 30 are made of a thin, helically wound wire 52, as shown in FIG. 4. The guide elements 29, 30 are thus designed as long and thin coil springs.

Anhand der Figuren 5 und 6 soll nun die Art der Lagerung der Pressrollen 3, 4, 5 und 6 beschrieben werden.The type of mounting of the press rollers 3, 4, 5 and 6 will now be described with reference to FIGS. 5 and 6.

Die Pressrollen 3, 4, 5 und 6 sind mittels Kugellagern 53 bzw. 54 auf der zugeordneten Achse 9, 10, 11 bzw. 12 gelagert. Die ortsfesten Achsen 9 und 11 der oberen Pressrollen 3 und 5 sind in Lagerbuchsen 55 und 56 gehalten, die fest am Gestell 35 angebracht sind. Alle Pressrollen 3, 4, 5, 6 sind an ihrem Umfang mit Rillen 57 versehen, in die die Führungselemente 29 und 30 zu liegen kommen.The press rollers 3, 4, 5 and 6 are mounted on the associated axes 9, 10, 11 and 12 by means of ball bearings 53 and 54, respectively. The stationary axes 9 and 11 of the upper press rollers 3 and 5 are held in bearing bushes 55 and 56 which are fixedly attached to the frame 35. All press rollers 3, 4, 5, 6 are provided on their circumference with grooves 57 into which the guide elements 29 and 30 come to rest.

Die Achsen 10 bzw. 12 der unteren Pressrollen 4 bzw. 6 sind ebenfalls in Lagerbuchsen 58 und 59 gehalten, die an einer beiden Pressrollen 4 und 6 gemeinsamen Lagerplatte 60 und 61 angebracht sind. Jede dieser Lagerplatten 60, 61 ist mittels eines Verbindungsbolzens 62 bzw. 63 mit dem einen Schenkel eines L-Profils 64 bzw. 65 verbunden. Diese Verbindungsbolzen 62, 63 erstrecken sich durch ein Langloch 66 (Fig. 6) in einer Seitenwand 35a bzw. 35b des Gestelles 35. Der andere Schenkel des L-Profils 64 bzw. 65 ist mit dem oberen Ende der zugeordneten Luftfeder 16 fest verbunden. Auf diesem Schenkel des L-Profils 64 bzw. 65 liegen je zwei Dämpfungselemente 67, 68 aus Gummi auf, die zu einer Einstellvorrichtung 69 gehören, die in Fig. 5 dargestellt ist. Die Dämpfungselemente 67, 68 sind an einer Platte 70, bzw. 71 befestigt, die mit einem Rohrstück 72, 73 mit einem Innengewinde fest verbunden ist. In die Innengewinde der Rohrstücke 72, 73 greift ein Gewindebolzen 74, 75 ein, der in einem an der Gestellwand 35a bzw. 35b befestigten Führungsteil 76 bzw. 77 drehbar gelagert ist. Jeder Gewindebolzen 74, 75 ist drehfest mit einem Kegelrad 78 bzw. 79 verbunden, das mit einem weitern Kegelrad 80 bzw. 81 in Eingriff steht. Die Kegelräder 80 und 81 sitzen drehfest auf einer Welle 82, die mittels eines Handrades 83 gedreht werden kann. Zur Arretierung der Welle 82 ist eine von Hand betätigbare Arretiervorrichtung 84 vorgesehen.The axes 10 and 12 of the lower press rollers 4 and 6 are also held in bearing bushes 58 and 59 which are attached to a bearing plate 60 and 61 common to both press rollers 4 and 6. Each of these bearing plates 60, 61 is connected to one leg of an L-profile 64 or 65 by means of a connecting bolt 62 or 63. These connecting bolts 62, 63 extend through an elongated hole 66 (FIG. 6) in a side wall 35a or 35b of the frame 35. The other leg of the L-profile 64 or 65 is firmly connected to the upper end of the associated air spring 16. On this leg of the L-profile 64 and 65 there are two rubber damping elements 67, 68, which belong to an adjusting device 69, which is shown in FIG. 5. The damping elements 67, 68 are fastened to a plate 70 or 71, which is fixedly connected to a pipe section 72, 73 with an internal thread. A threaded bolt 74, 75 engages in the internal thread of the tube pieces 72, 73 and is rotatably mounted in a guide part 76 or 77 fastened to the frame wall 35a or 35b. Each threaded bolt 74, 75 is non-rotatably connected to a bevel gear 78 or 79, which is in engagement with a further bevel gear 80 or 81. The bevel gears 80 and 81 are non-rotatably seated on a shaft 82 which can be rotated by means of a handwheel 83. A manually operable locking device 84 is provided for locking the shaft 82.

Mittels der Einstellvorrichtung 69 kann die Grösse der Durchgangsspalte 7 und 8 eingestellt werden. Durch Drehen des Handrades 83 werden die Platten 70 und 71 mit den Dämpfungselementen 67 und 68 angehoben und abgesenkt. Diese Heb- und Senkbewegung der Dämpfungselemente 67, 68 wird auf die L-Profile 64, 65 übertragen, was ein entsprechendes Heben und Senken der Achsen 10 und 12 und der auf diesen gelagerten Pressrollen 4 und 6 zur Folge hat. Die Luftfedern 16 folgen dieser Bewegung der L-Profile 64, 65. In den Figuren 2, 5 und 6 sind strichpunktiert die Pressrollen 4 und 6 und die sich mit diesen mitbewegenden Bauteile in ihrer unteren Endlage gezeigt und mit dem zugeordneten, mit einem ' versehenen Bezugszeichen bezeichnet. Wie Fig. 6 zeigt stehen die sich in der unteren Endlage befindlichen Pressrollen 4' und 6' mit dem obern Trum der Führungselemente 30' nicht mehr in Berührung. In dieser unteren Endlage der Pressrollen 4', 6' erfolgt keine Pressung der Druckereierzeugnisse 33 mehr.The size of the passage gaps 7 and 8 can be adjusted by means of the adjusting device 69. By turning the handwheel 83, the plates 70 and 71 with the damping elements 67 and 68 are raised and lowered. This lifting and lowering movement of the damping elements 67, 68 is transmitted to the L-profiles 64, 65, which results in a corresponding lifting and lowering of the axes 10 and 12 and the press rollers 4 and 6 mounted on them. The air springs 16 follow this movement of the L-profiles 64, 65. In FIGS. 2, 5 and 6, the press rollers 4 and 6 and the components moving with them are shown in dash-dot lines in their lower end position and with the associated one provided with a ' Reference numerals. As shown in FIG. 6, the press rollers 4 'and 6' located in the lower end position are no longer in contact with the upper run of the guide elements 30 '. In this lower end position of the press rollers 4 ', 6', the printed products 33 are no longer pressed.

Nachfolgend wird der Pressvorgang, soweit er sich nicht bereits aus den vorstehenden Ausführungen ergibt, noch erläutert.In the following, the pressing process, insofar as it does not already result from the above explanations, is still explained.

Die in Förderrichtung F dem ersten Pressrollenpaar 1 zugeführten Druckereierzeugnisse 33 werden durch die Führungselemente 29, 30 zum Durchgangsspalt 7 zwischen den Pressrollen 3 und 4 geführt. Beim Durchlaufen dieses Durchgangsspaltes 7 erfolgt ein erstes Pressen der Druckereierzeugnisse 33. Für ein starkes Verdichten der Druckereierzeugnisse 33 ist es von Wichtigkeit, dass die oben liegenden Falzkanten 33a der Druckereierzeugnisse 33 mit der ortsfesten Pressrolle 3 in Berührung kommen. Die Druckereierzeugnisse 33 gelangen dann in den zweiten Durchgangsspalt 8 zwischen den Pressrollen 5 und 6 des zweiten Pressrollenpaares 2. Die Abschnitte 29a und 30a der Führungselemente 29 und 30 verhindern, dass während dieser Bewegung der Druckereierzeugnisse 33 letztere in den Zwischenraum 31 bzw. 32 zwischen den Pressrollen 3 und 5 bzw. 4 und 6 eintreten können. Beim Durchlaufen durch den zweiten Durchgangsspalt 8 erfolgt ein nochmaliges Zusammenpressen der Druckereierzeugnisse 33.The printed products 33 fed to the first pair of press rollers 1 in the conveying direction F are guided by the guide elements 29, 30 to the passage gap 7 between the press rollers 3 and 4. When passing through this passage gap 7, the printed products 33 are first pressed. For a strong compression of the printed products 33, it is important that the fold edges 33a of the printed products 33 lying on top come into contact with the stationary press roller 3. The printed products 33 then pass into the second passage gap 8 between the press rollers 5 and 6 of the second pair of press rollers 2. The sections 29a and 30a of the guide elements 29 and 30 prevent this during this Movement of the printed products 33 the latter can occur in the intermediate space 31 or 32 between the press rollers 3 and 5 or 4 and 6. When passing through the second passage gap 8, the printed products 33 are compressed again.

Die unteren Pressrollen 4, 6 sind durch die Luftfedern 16 federnd abgestützt, was es diesen Pressrollen 4, 6 ermöglicht, den Dickenunterschieden in der Schuppenformation S zu folgen. Durch den Einsatz von Luftfedern 16, die rascher auf Belastungsschwankungen ansprechen als Schraubenfedern, ist es möglich, die Pressrollen 4, 6 immer der Kontur der Schuppenformation S nachzuführen. Die Kraft, die die Druckfedern 16 ausüben, kann auf einfache Weise mittels der Druckregeleinheit 50 verändert und auf den jeweils gewünschten Wert eingestellt werden. Die beschriebene Ausbildung der Lagerung der Wellen 10, 12 der Pressrollen 4, 6 ermöglicht auch eine gewisse Schwenk- oder Wippbewegung der Lagerplatten 60, 61 um die Längsachse der Verbindungsbolzen 62, 63. Diese Schwenkbewegung wird durch die Dämpfungselemente 67, 68 gedämpft.The lower press rolls 4, 6 are supported by the air springs 16, which enables these press rolls 4, 6 to follow the differences in thickness in the scale formation S. By using air springs 16, which respond more quickly to load fluctuations than helical springs, it is possible to always press rollers 4, 6 to follow the contour of scale formation S. The force exerted by the compression springs 16 can be changed in a simple manner by means of the pressure control unit 50 and set to the desired value. The described design of the mounting of the shafts 10, 12 of the press rollers 4, 6 also enables a certain pivoting or rocking movement of the bearing plates 60, 61 about the longitudinal axis of the connecting bolts 62, 63. This pivoting movement is damped by the damping elements 67, 68.

Falls eine Schuppenformation zu verarbeiten ist, in der anders als wie in Fig. 1 gezeigt jedes Druckereierzeugnis auf dem nachlaufenden Druckereierzeugnis aufliegt und die vorlaufende Falzkante somit auf der Unterseite der Schuppenformation liegt, so müssen die ortsfesten und abgefederten Pressrollen gegeneinander vertauscht werden, d.h. die ortsfesten Pressrollen sind dann auf der Unterseite der Schuppenformation anzuordnen, damit sie auch in diesem Fall direkt auf die Falzkanten der Druckereierzeugnisse einwirken können.If a scale formation is to be processed in which, unlike as shown in Fig. 1, each printed product rests on the trailing printed product and the leading fold edge thus lies on the underside of the scale formation, the stationary and spring-loaded press rolls must be interchanged, i.e. the stationary press rolls are then to be arranged on the underside of the scale formation so that they can also act directly on the folded edges of the printed products in this case.
