Abstract

In a method for manufacturing a printing product from a multiplicity of sheets lying one above the other in a rotary printing machine, in which method, to form the printing product in the rotary printing machine, the sheets lying one above the other are folded together once along their transverse centre line, a considerable amount of waste paper is produced due to the prefold or return fold required for opening the printing product out again. To avoid this waste, the multiplicity of sheets of the printing product are joined together at least on one side extending transversely to the delivery direction in the region of the trimming edge prior to delivery by the rotary printing machine, in such a way that the prefold or return fold can be omitted and it is still possible for the printing product to be opened out again.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Druckprodukts, bei dem in einer Rotationsdruckmaschine eine Papierbahn bedruckt und in eine Vielzahl von Blättern glei­cher Größe zerteilt wird und diese Blätter übereinander geschichtet und zur Bildung des Druckprodukts einmal ent­lang ihrer Quermittellinie zusammengefaltet werden, wo­nach das Druckprodukt von der Rotationsdruckmaschine ab­gegeben, vorübergehend wieder aufgefaltet, in dem entlang der Quermittellinie verlaufenden Mittelfalz zusammengehef­tet und schließlich an drei Seiten auf das Endformat be­schnitten wird.The invention relates to a method for producing a printed product, in which a paper web is printed in a rotary printing press and divided into a plurality of sheets of the same size, and these sheets are stacked on top of one another and folded once along their transverse center line to form the printed product, after which the printed product is moved from the Rotary printing press delivered, temporarily unfolded, in the center fold running along the transverse center line and finally trimmed to the final format on three sides.

Ein derartiges Verfahren ist nach dem Stand der Technik beispielsweise aus der DE-PS 26 49 757 bekannt. Bei die­sem Verfahren wird in einer Rotationsdruckmaschine die bedruckte Papierbahn durch eine Längsschlitzung in zwei gleich breite Teilbahnen aufgeteilt, dann die beiden Teil­bahnen aufeinandergeführt und entlang ihrer gemeinsamen Längsmitte einmal zusammengefaltet. Diese vierlagige Bahn wird quer zur Abgaberichtung durchtrennt und mit etwas überstehendem Rand quer gefaltet. In den Figuren 1 und 2 ist das bei dem bekannten Verfahren nun vorlie­gende Produkt dargestellt. Wie ersichtlich, ist das in diesem Verfahrensstand vorliegende Druckprodukt 1 mit ei­nem quer zur durch den Pfeil 2 angegebenen Abgaberichtung des Produkts aus der Rotationsmaschine verlaufenden Mit­telfalz 8 derart gefaltet, daß sich ein als "Nachfalz" 5 bezeichneter überstehender Rand ergibt. Das Druck­produkt wird dann in eine Maschine eingeführt, in wel­cher der Nachfalz mit einem Klemmgreifer 7 ergriffen wird und das Druckprodukt 1 vorübergehend wieder aufge­faltet wird (siehe Fig. 2), damit beispielsweise mehrere Druckprodukte zur Bildung einer kompletten Zeitschrift oder einer ähnlichen Broschüre zusammengesteckt werden können und damit vor allem in den Mittelfalz 8 Heft­klammern 6 eingesetzt werden können, um die Blätter des Druckerzeugnisses zusammenzuhalten. Danach wird das ge­samte Druckerzeugnis unter Bildung des Heftrückens 9 wieder zusammengefaltet und schließlich entlang des For­matrandes 3 dreiseitig beschnitten. Es fallen dabei als Abfallstreifen die am oberen, am unteren und an den bei­den Seitenrändern vorgesehenen Beschnittränder 4 an, und zusätzlich noch als Abfall der verhältnismäßig brei­te Nachfalz 5.Such a method is known from the prior art, for example from DE-PS 26 49 757. In this method, the printed paper web is divided into two equally wide partial webs by means of a longitudinal slit in a rotary printing press, then the two partial webs are brought together and folded together once along their common longitudinal center. This four-ply web is cut transversely to the dispensing direction and folded transversely with a slightly protruding edge. FIGS. 1 and 2 show the product now available in the known method. As can be seen, the printed product 1 present in this state of the art is folded with a central fold 8 extending transversely to the direction of discharge of the product from the rotary machine indicated by the arrow 2 in such a way that a protruding edge, referred to as "post-fold" 5, results. The printed product is then introduced into a machine in which the refolding is gripped with a clamping gripper 7 and the printed product 1 is temporarily unfolded again (see FIG. 2) so that, for example, several printed products can be put together to form a complete magazine or a similar brochure and thus 8 staples 6 can be used especially in the middle fold to hold the sheets of the printed product together. Thereafter, the entire printed product is folded together again to form the spine 9 and finally trimmed on three sides along the format edge 3. The trimmed edges 4 provided on the upper, on the lower and on the two side edges are obtained as waste strips, and the relatively wide secondary fold 5 is also added as waste.

Der überstehende, je nach seiner Lage zur Abgaberichtung gemäß Pfeil 2 der Druckprodukte von der Rotationsdruck­maschine als "Vorfalz" oder "Nachfalz" genannte Rand muß eine bestimmte Mindestbreite haben, damit der oder die Klemmgreifer 7 der nachfolgenden Bearbeitungsmaschine zuverlässig angreifen können. Üblicherweise beträgt die Mindestbreite B dieses Nachfalzes 5 etwa 8 bis 10 mm, und zwar zusätzlich zu dem Beschnittrand, der seinerseits eine Breite b von etwa 4 mm besitzt. Es entstehen also ganz erhebliche Abfallmengen, die einen nennenswerten Kostenfaktor bei der Herstellung darstellen. Der Nach­falz bzw. Vorfalz allein macht dabei eine Abfallmenge von etwa 1 bis 1,5 % der gesamten eingesetzten Papiermen­ge aus.The protruding edge, depending on its position in relation to the direction of discharge according to arrow 2 of the printed products from the rotary printing machine as "pre-fold" or "post-fold", must have a certain minimum width so that the clamping gripper or grippers 7 can reliably attack the subsequent processing machine. The minimum width B of this rebate 5 is usually about 8 to 10 mm, in addition to the trimmed edge, which in turn has a width b of about 4 mm. So there are very significant amounts of waste, which represent a significant cost factor in production. The post-fold or pre-fold alone makes up a waste amount of about 1 to 1.5% of the total amount of paper used.

Die DE-PS 26 49 757 beschreibt bereits Maßnahmen, mit denen eine Verminderung der durch den Nachfalz entstehen­den Abfallmenge angestrebt wird.DE-PS 26 49 757 already describes measures with which a reduction in the amount of waste produced by the rebate is aimed for.

Die der Erfindung zugrundeliegende Aufgabe besteht da­rin, bei einem Verfahren der eingangs genannten Gattung den Papierabfall weiter zu vermindern.The object on which the invention is based is to further reduce paper waste in a method of the type mentioned at the outset.

Gemäß der Erfindung wird diese Aufgabe bei einem Verfah­ren der eingangs genannten Art dadurch gelöst, daß die Vielzahl der Blätter des Druckprodukts vor der Abgabe von der Rotationsdruckmaschine wenigstens an einem der quer zur Abgaberichtung verlaufenden Seitenränder im Be­reich des Beschnittrandes miteinander verbunden werden.According to the invention, this object is achieved in a method of the type mentioned in the introduction in that the plurality of sheets of the printed product are connected to one another in the region of the trimming edge at least on one of the lateral edges which run transversely to the direction of discharge, before being released from the rotary printing machine.

Durch diese erfindungsgemäße Ausgestaltung wird erreicht, daß die einzelnen Blätter des Druckprodukts an dieser wenigstens einen Seitenkante miteinander verbunden sind, so daß es zum Auffalten des Druckproduktes genügt, das oberste Blatt des Druckproduktes von seiner freien Ober­ fläche her zu ergreifen. Die mit diesem obersten Blatt ver­bundenen darunterliegenden Blätter werden dabei mitge­zogen, so daß das Druckprodukt zuverlässig aufgefaltet werden kann, ohne daß es notwendig wäre, daß ein Klemm­greifer den freien Rand eines Vorfalzes oder Rückfalzes von beiden Seiten her umgreifen kann. Dieser Vorfalz oder Rückfalz kann daher ersatzlos weggelassen werden, so daß sich erhebliche Papiereinsparungen erzielen lassen.This configuration according to the invention ensures that the individual sheets of the printed product are connected to one another at this at least one side edge, so that it is sufficient to unfold the printed product, the uppermost sheet of the printed product from its free top to seize area. The underlying sheets connected to this uppermost sheet are pulled along, so that the printed product can be unfolded reliably without it being necessary for a clamping gripper to be able to grip around the free edge of a pre-fold or reverse fold from both sides. This pre-fold or reverse fold can therefore be omitted without replacement, so that considerable paper savings can be achieved.

Besonders bevorzugt ist es, daß das vorübergehende Wieder­auffalten des Druckprodukts mittels Sauggreifern erfolgt. Derartige Sauggreifer werden einfach an die freie Ober­fläche eines Blattes des Druckproduktes in der Nähe des jeweiligen Seitenrandes angeordnet, wobei durch Saugluft dieses Blatt von den Greifern ergriffen und dabei die mit dem Blatt fest verbundenen übrigen Blätter des Druck­produktes mitgezogen werden.It is particularly preferred that the temporary refolding of the printed product takes place by means of suction pads. Such suction pads are simply arranged on the free surface of a sheet of the printed product in the vicinity of the respective side edge, this sheet being gripped by the grippers by suction air and the remaining sheets of the printed product firmly attached to the sheet being pulled along.

Bei einer Ausführungsform der erfindungsgemäßen Verfahrens­führung ist vorgesehen, daß die Verbindung der Blätter des Druckproduks am Seitenrand durch eine Verklebung, beispiels­weise eine Heißverklebung oder eine Fadenheftung erfolgt. Die Verklebung kann beispielsweise stirnseitig am Seiten­rand mit einem Heißkleber erfolgen. In beiden Fällen er­gibt sich der Vorteil, daß beim nachträglichen Formatbe­schneiden eine Verletzung der Schneidmesser durch harte Verbindungselemente vermieden wird.In one embodiment of the method according to the invention it is provided that the connection of the sheets of the printed product at the side edge takes place by means of an adhesive, for example a hot adhesive or a thread stitching. For example, the glue can be glued on the end face using a hot glue. In both cases, there is the advantage that injury to the cutting knives due to hard connecting elements is avoided during subsequent format trimming.

Besonders bevorzugt ist es allerdings, daß die Verbindung der Blätter des Druckproduktes am Seitenrand durch eine Prägeheftung erfolgt. Eine derartige Prägeheftung ist nach dem Stand der Technik bekannt. Sie besteht aus einem klei­nen Bereich, in dem mittels geeigneter Prägestempel die einzelnen Blätter des Druckprodukts lokal gegenüber den benachbarten Blättern verschränkt werden, so daß die Blät­ter jeweils an ihren Nachbarn verankert werden und damit alle Blätter des Druckprodukts an diesem Seitenrand aus­reichend fest miteinander verbunden werden.It is particularly preferred, however, for the sheets of the printed product to be connected by embossing at the side edge. Such a stitching is known in the prior art. It consists of a small area in which the individual sheets of the printed product are locally entangled with the adjacent sheets by means of suitable embossing stamps, so that the sheets are anchored to their neighbors and thus all sheets of the printed product are sufficiently firmly connected to each other on this page margin.

Vorteilhaft ist es, daß die Prägeheftung unter Verwen­dung einer Heftertrommel in der Rotationsmaschine herge­stellt werden kann.It is advantageous that the embossing can be produced in the rotary machine using a stapling drum.

Bei einer besonders bevorzugten Ausgestaltung ist es schließlich vorgesehen, daß auch die Heftung des Druck­produktes im Mittelfalz nach dem Widerauffalten als Prä­geheftung ausgeführt wird. Es kann dadurch auf die üblichen Drahtheftklammern verzichtet werden, die einerseits bei der Wiederverwendung des Druckproduktes als Altpapier stö­ren und andererseits gelegentlich zu Verletzungen des Be­nutzers führen.In a particularly preferred embodiment, it is finally provided that the stitching of the printed product in the center fold after the unfolding is also carried out as an embossing stitch. As a result, the usual wire staples can be dispensed with, which on the one hand interfere with the reuse of the printed product as waste paper and on the other hand occasionally lead to injuries to the user.

Die Erfindung wird im folgenden beispielsweise unter Be­zugnahme auf die Zeichnung näher erläutert; es zeigt:

  • Fig. 1 eine schematische perspektivische Darstellung eines Druckprodukts nach dem Stand der Tech­nik mit Rückfalz;
  • Fig. 2 eine Draufsicht auf das auseinandergefaltete Druckprodukt der Fig. 1;
  • Fig. 3 eine perspektivische Ansicht des erfindungs­gemäßen Druckprodukts; und
  • Fig. 4 eine Draufsicht auf das auseinandergefaltete Druckprodukt der Fig. 3.
The invention is explained in more detail below, for example with reference to the drawing; it shows:
  • Figure 1 is a schematic perspective view of a printed product according to the prior art with fold back.
  • FIG. 2 is a top view of the unfolded printed product of FIG. 1;
  • 3 shows a perspective view of the printed product according to the invention; and
  • 4 is a plan view of the unfolded printed product of FIG. 3.

In der Fig. 3 ist ein in einer Rotationsdruckmaschine her­gestelltes Druckprodukt 11 dargestellt, das aus einer Viel­zahl von übereinanderliegenden Blättern gleichen Formats besteht und von einer Rotationsdruckmaschine in Richtung des Pfeiles 12 abgegeben wurde. In der Rotationsmaschine wird zur Herstellung des Druckprodukts zunächst eine fort­laufende Papierbahn bedruckt und anschließend in Längs­richtung und in Querrichtung in Blätter zerschnitten, die zur Bildung des Druckprodukts 11 aufeinander gelegt und zur Bildung des Heftrückens 19 um eine senkrecht zur Ab­gaberichtung des Pfeiles 12 verlaufende Quermittellinie 18 zusammengefaltet werden. Das Zusammenfalten erfolgt da­bei derart, daß die Seitenkanten 15 der Blätter in etwa bündig miteinander abschließen. Ein Rückfalz oder Vorfalz wie beim Stand der Technik wird also nicht gebildet.FIG. 3 shows a printed product 11 produced in a rotary printing press, which consists of a plurality of sheets of the same format lying one above the other and in the direction of a rotary printing press the arrow 12 was delivered. To produce the printed product, a continuous paper web is first printed in the rotary machine and then cut into sheets in the longitudinal and transverse directions, which are laid one on top of the other to form the printed product 11 and folded to form the spine 19 around a transverse center line 18 running perpendicular to the direction of discharge of the arrow 12 will. The folding takes place in such a way that the side edges 15 of the sheets are approximately flush with one another. A reverse fold or pre-fold as in the prior art is therefore not formed.

Vor der Abgabe aus der Rotationsdruckmaschine und vor­zugsweise vor der Bildung des Mittelfalzes entlang der Quermittellnie 18 werden die einzelnen Blätter des Druck­produkts 11 im Bereich des Beschnittrandes 14 und beispiels­weise an der in Abgaberichtung voreilenden querlaufenden Seitenkante 15 mit mehreren im Abstand zueinander ange­ordneten Prägeheftungen 20 fest miteinander verbunden.Before delivery from the rotary printing machine and preferably before the formation of the middle fold along the transverse center line 18, the individual sheets of the printed product 11 are firmly connected to one another in the region of the trimmed edge 14 and, for example, on the transverse side edge 15 leading in the delivery direction, with a plurality of embossing booklets 20 arranged at a distance from one another .

Derartige Prägeheftungen sind nach dem Stand der Technik bekannt, sie werden beispielsweise zum klammerlosen Ver­binden der einzelnen Blätter von Schriftstücken anstelle eines Klammerhefters verwendet. Entsprechende Prägeheft­geräte für den Schreibtischgebrauch sind im Handel ver­fügbar. Auch die Bezeichnung "Quetschheftung" ist gebräuchlich.Embossing of this type is known from the prior art and is used, for example, for connecting the individual sheets of documents without clips instead of a stapler. Corresponding embossing devices for desk use are commercially available. The term "pinch stitch" is also common.

Eine derartige Prägeheftung besteht im allgemeinen aus einem länglichen schmalen, beispielsweise rechteckigen Bereich, in welchem mittels eines Prägestempels die ein­zelnen Blätter eines Stapels von Blättern lokal begrenzt in die Ebene der jeweils benachbarten Blätter hineinge­stanzt verschoben werden, so daß sich die Blätter an die­sen Stanzkanten bzw. Quetschkanten gegeneinander verklemmen und dadurch die benachbarten Blätter in einem Stapel je­weils fest haftend miteinander verbunden werden.Such embossing generally consists of an elongated, narrow, for example rectangular area, in which the individual sheets of a stack of sheets are punched into the plane of the adjacent sheets in a locally limited manner by means of an embossing stamp, so that the sheets at these cutting edges or Clamp the crimped edges against each other and thereby the adjacent sheets in a stack are firmly bonded to one another.

Bei der erfindugnsgemäßen Verfahrensführung werden diese Prägeheftungen unter Verwendung einer Hefttrommel inner­halb der Rotationsmaschine hergestellt. Derartige Heft­trommeln wurden nach dem Stand der Technik schon früher in Rotationsmaschinen zur Herstellung von Drahtheftungen eingesetzt. Zur Herstellung von Prägeheftungen nach dem erfindungsgemäßen Verfahren können derartige bekannte Heft­trommeln mit geeigneten Prägestempeln umgerüstet werden.In the process control according to the invention, these embossed staplings are produced using a stapling drum within the rotary machine. Such stapling drums have previously been used in the prior art in rotary machines for the production of wire stapling. In order to produce embossed stitching using the method according to the invention, such known stitching drums can be converted with suitable embossing stamps.

Durch diese Prägeheftungen 20 am Seitenrand 15 des Druck­produktes 11 werden die einzelnen Blätter des Druckpro­duktes 11 im Bereich des Seitenrandes 15 fest miteinander verbunden. Das von der Rotationsmaschine 11 abgegebene Druckprodukt gemäß Fig. 3 kann daher nachfolgend dadurch wieder aufgefaltet werden, daß an der freien Oberfläche eines Blattes des Druckprodukts Sauggreifer 17 angesetzt werden, wie in der Fig. 3 gezeigt. Diese Sauggreifer er­fassen natürlich zunächst nur das oberste Blatt des Druck­produktes, doch werden die an diesem Blatt im Bereich des Seitenrandes 15 daran haftenden übrigen Blätter des Druck­produktes 11 mitgezogen, so daß das Druckprodukt 11 mit­tels der Sauggreifer 17 in die geöffnete Stellung der Fig. 4 aufgefaltet werden kann.By means of these embossed stitching 20 on the side edge 15 of the printed product 11, the individual sheets of the printed product 11 are firmly connected to one another in the region of the side edge 15. 3 can therefore subsequently be unfolded again by applying suction pads 17 to the free surface of a sheet of the printed product, as shown in FIG. 3. Of course, these suction pads initially only grasp the top sheet of the printed product, but the remaining sheets of the printed product 11 adhering to this sheet in the region of the side edge 15 are pulled along, so that the printed product 11 is unfolded into the open position of FIG. 4 by means of the suction pads 17 can be.

In dieser aufgefalteten Stellung gemäß Fig. 4 kann das Druckprodukt mit weiteren Druckprodukten beispielsweise zur Bildung einer umfangreichen Zeitschrift zusammenge­steckt werden und es kann schließlich die Heftung im Mittelfalz entlang der Quermittellinie 18 ausgeführt wer­den, in der die Blätter des einen oder der mehreren inein­ander gesteckten Druckprodukte und gegebenenfalls eines zusätzlichen Umschlages zur Bildung einer Zeitschrift oder eines ähnlichen Druckproduktes fest miteinander ver­bunden werden. Bei der beschriebenen Ausführungsform des Verfahrens werden diese Heftungen im Mittelfalz ebenso wie die Heftungen im Bereich der Seitenkante 15 als Prägehef­tungen 21 ausgeführt, die ähnlich wie die vorstehend er­läuterten Prägeheftungen 20 ausgeführt sind.In this unfolded position according to FIG. 4, the printed product can be put together with further printed products, for example to form an extensive magazine, and finally the stitching in the middle fold can be carried out along the transverse center line 18, in which the sheets of the one or more printed products and one inside the other if necessary, an additional cover to form a magazine or a similar printed product. In the described embodiment of the method, these staplings in the center fold, like the staplings in the region of the side edge 15, are designed as embossed stitchings 21, which are similar to the above-described embossed stitching 20.

Eine derartige Heftung des Druckerzeugnisses mit Präge­heftungen 21 hat den Vorteil, daß die nach dem Stand der Technik üblichen Drahtheftklammern weggelassen werden kön­nen, die nicht nur eine Verletzungsgefahr für die Benutzer des Druckerzeugnisses darstellen, sondern auch bei der Wiederverwertung des Druckerzeugnisses als Altpapier hin­derlich sind.Such a stitching of the printed matter with embossed stitching 21 has the advantage that the wire staples customary in the prior art can be omitted, which not only pose a risk of injury to the users of the printed matter, but are also a hindrance when the printed matter is recycled as waste paper.

Nach Durchführung der vorstehend erläuterten Arbeitsgänge wird das Druckprodukt wieder in den Zustand der Fig. 3 zurückgefaltet und nun abschließend an drei Seiten entlang der Formatlinie 13 auf das endgültige Format beschnitten.After carrying out the operations described above, the printed product is folded back into the state of FIG. 3 and now finally trimmed to the final format on three sides along the format line 13.

Die Breite b des die Formatlinie 13 umgebenden Beschnitt­randes 14 beträgt in der Praxis etwa 4 mm. Der dadurch ver­ursachte Papierabfall ist nicht vermeidbar, wenn ein Druck­erzeugnis mit sauber beschnittenen Rändern erzeugt werden soll. Bei der erfindungsgemäßen Verfahrensausgestaltung entsteht hingegen durch Wegfall des Vor- oder Nachfalzes, dessen Breite B nach dem Stand der Technik etwa 8 bis 10 mm betrug, immerhin eine Papiereinsparung von 1 bis 1,5 %.The width b of the trimmed edge 14 surrounding the format line 13 is in practice approximately 4 mm. The paper waste caused by this is unavoidable if a printed product with cleanly trimmed edges is to be produced. In the process design according to the invention, on the other hand, the omission of the pre-fold or post-fold, the width B of which according to the prior art was approximately 8 to 10 mm, results in a paper saving of 1 to 1.5%.
