Abstract

Printed products having a center fold are provided with appropriate product break structure for facilitating opening of the printed products. Such product break structure comprises a crimp structure which may be in the form of impressions or embossments. This crimp structure is provided in the region of one end of the center fold of the printed products to be opened. These crimp structures mutually converge in relation to one another and extend to a common point located on the center fold of the printed products. Each of the printed products can be opened at the center fold by applying or exerting pressure on the folded edge or spine of the printed products at the end of the center fold which is provided with the crimp structure. An opening element can enter the opening thus formed for separating the two halves of each of the printed products.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Oeffnen von mit einem Mittelfalz versehenen Druckereierzeugnissen durch Druckausübung auf das eine Ende des Falzrückens, wobei die entstandene Oeffnung bestimmt ist, das Ende eines Oeffnungsgliedes eindringen zu lassen.The present invention relates to a method for opening printed products provided with a central fold by exerting pressure on one end of the fold back, the opening formed being intended to allow the end of an opening member to penetrate.

Ein solches Verfahren ist zum maschinellen Einlegen von Beilagen in mit einem Mittelfalz versehene bedruckte Hefte aus der CH-PS 358 444 bekanntgeworden. Zum Oeffnen der Druckereierzeugnisse ist dabei allerdings ein erheblicher maschineller Aufwand erforderlich. Die Produkte ruhen mit dem Falzrücken auf einem Förderband und sie sind durch zwei an beiden Seiten angeordnete Führungsschienen während des Förderns in aufrechter Lage gehalten. Unmittelbar bevor ein Produkt vor einen Oeffnungskeil gelangt, wird es von beiden Seiten von Andruckrollen erfasst, die das Produkt in Förderrichtung durchlassen, seine Verschiebung nach oben aber verhindern. Alsdann wird auf die vordere untere Ecke des Produkts mit Hilfe einer Nockenscheibe von unten her ein Druck ausgeübt, so dass im Bereich des Mittelfalzes eine Oeffnung entsteht, in die beim Weitertransport des Produktes der Oeffnungskeil eindringt.Such a method has become known from CH-PS 358 444 for the mechanical insertion of inserts into printed booklets provided with a central fold. However, considerable mechanical effort is required to open the printed products. The products rest on a conveyor belt with the fold back and they are held in an upright position during conveying by two guide rails arranged on both sides. Immediately before a product reaches an opening wedge, it is gripped by pressure rollers on both sides, which pass the product in the direction of conveyance, but prevent it from moving upwards. Then pressure is exerted on the lower front corner of the product with the aid of a cam disk from below, so that an opening is created in the region of the central fold, into which the opening wedge penetrates when the product is transported further.

Dem erfindungsgemässen Verfahren liegt die Aufgabe zugrunde, den zum Oeffnen erforderlichen maschinellen Aufwand auf das absolute Minimum zu vermindern, zugleich aber die Sicherheit des Oeffnens zu erhöhen. Gelingt dies, so ermöglicht das erfindungsgemässe Verfahren in Erweiterung der ihm zugrunde liegenden Aufgabe das Oeffnen von mehrblättrigen Druckereierzeugnissen in Tabloidform, ohne dass dazu diese den üblichen Vorfatz aufweisen müssten. Daraus ergibt sich eine drastische Verringerung des Papierabfalls, dessen Wert jedenfalls in Zeitschriftendruckereien in die Millionen geht.The object of the method according to the invention is to reduce the mechanical effort required for opening to the absolute minimum, but at the same time to increase the security of the opening. If this succeeds, the method according to the invention, in addition to the task on which it is based, enables the opening of multi-sheet printed products in tabloid form, without these having to have the usual prefix. This results in a drastic reduction in paper waste, the value of which, at least in magazine printing plants, is in the millions.

Die Lösung für diese Aufgabe bzw. Aufgaben ergibt sich aus dem kennzeichnenden Teil des Patentanspruchs 1.The solution to this task or tasks results from the characterizing part of patent claim 1.

Weitere Einzelheiten ergeben sich aus der beiliegenden Zeichnung. Es zeigen dieFurther details can be found in the attached drawing. They show

Figuren 1 und 2 bzw. 3 und 4 je ein Produkt in Tabloidform noch geschlossen, aber bereits während der Druckausübung bzw. vollständig aufgefaltet.Figures 1 and 2 or 3 and 4 each a product in tabloid form still closed, but already unfolded during the application of pressure or fully.

Der Unterschied zwischen den Druckprodukten 1 und 2 gemäss Figuren 1 und 2 einerseits und Figuren 3 und 4 andererseits besteht lediglich darin, dass beim Produkt 1 die Sicken 3, 4 gegen das Ende der Falzkante 5, d. h. gegen die seitliche Produktkante 6, gemäss den Figuren 3 und 4 hingegen in der umgekehrten Richtung konvergieren, wobei die Sicken 3, 4 im erstgenannten Fall im Bereiche der Seitenkante 6 den Mittelfalz 5 erreichen. Dank dieser Massnahme öffnet sichThe difference between the printed products 1 and 2 according to FIGS. 1 and 2 on the one hand and FIGS. 3 and 4 on the other hand is only that in the case of the product 1, the beads 3, 4 toward the end of the folded edge 5, ie. H. 3 and 4, on the other hand, converge in the opposite direction, the beads 3, 4 reaching the central fold 5 in the region of the side edge 6 in the former case. Thanks to this measure opens

- wie in den Figuren 1 und 3 angedeutet ist - das Produkt 1, 2 im Mittelfalz 5 allein schon dadurch, dass auf das Ende des Falzrückens 7 - wie durch den Pfeil A angedeutet - ein Druck ausgeübt wird. Es ist nicht erforderlich, die Produkte 1, 2 im Bereiche der Seitenkante 6 gegen die Druckausübung abzustützen. Natürlich müssen die Produkte 1, 2 irgendwie gehalten werden. Wie aber dies geschieht, ist unerheblich. Hält man die Produkte 1, 2 im Bereiche der Falzkante 5 bzw. des Falzrückens 7, wobei sie - wie dargestellt - mit der Blume, d. h. der dem Falzrücken 7 gegenüberliegenden offenen Seitenkante 8, nach unten hängen, so können sie nach dem vollständigen Oeffnen ohne weiteres auf eine Sammelschiene oder dergleichen aufgesetzt werden.- As indicated in FIGS. 1 and 3 - the product 1, 2 in the middle fold 5 simply because pressure is exerted on the end of the fold back 7, as indicated by the arrow A. It is not necessary to support the products 1, 2 in the region of the side edge 6 against the application of pressure. Of course, products 1, 2 have to be kept somehow. How this happens is irrelevant. If you hold the products 1, 2 in the area of the folded edge 5 or the folded back 7, they - as shown - with the flower, i.e. H. of the open side edge 8 opposite the fold back 7, hang down so that they can be easily placed on a busbar or the like after the complete opening.

Verlaufen die Sicken 3, 4 wie in den Figuren 3 und 4 dargestellt, so dass sie den Mittelfalz 5 im Abstand von der Seitenkante 6 erreichen, so bilden sie nicht nur für sich eine Soll-Knickstelle ; eine solche entsteht vielmehr auch für den Mittelfalz 5, indem das Ende des Falzrückens 7 um den Schnittpunkt der Sicken 3, 4 abknicken kann. Verlaufen die Sicken 3,4 in umgekehrter Richtung (Figuren 1 und 2), so verhindern sie vorab, dass die Ecke unter Druckausübung nach der einen oder der anderen Seite ausweicht ; dem Nachgeben des Falzrückens 7 nach unten setzt aber keine der Sicken 3, 4 Widerstand entgegen, so dass die Druckausübung wiederum mit hoher Sicherheit zum Oeffnen im Mittelfalz 5 führt, gleichgültig, ob das Produkt 1, 2 aus einem, aus wenigen oder aus einer Vielzahl Doppelbögen besteht.If the beads 3, 4 run as shown in FIGS. 3 and 4, so that they reach the central fold 5 at a distance from the side edge 6, they not only form a desired kink for themselves; this also occurs for the middle fold 5, in that the end of the fold back 7 can bend around the intersection of the beads 3, 4. If the beads 3, 4 run in the opposite direction (FIGS. 1 and 2), they prevent the corner from moving under pressure to one side or the other; the yielding of the fold back 7 does not, however, provide any resistance to the beads 3, 4, so that the application of pressure in turn leads with a high degree of certainty to opening in the middle fold 5, irrespective of whether the product 1, 2 consists of one, a few or a large number Double arches exist.

Zum Anbringeh der Sicken 3,4 sind gemäss der Erfindung an einer Druckmaschine entsprechend ausgebildete Prägemittel vorgesehen. Deren Standort ergibt sich aus der Notwendigkeit, die Sicken 3, 4 vor dem Falten der Produkte 1, 2 anzubringen.According to the invention, appropriately designed embossing means are provided for attaching the beads 3, 4. Their location results from the need to attach the beads 3, 4 before folding the products 1, 2.
