Description
Die Erfindung betrifft eine Vorrichtung zum Aufrauhen eines
aus zusammengepressten einzelnen Druckbogen gebildeten Buchblockrückens
gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for roughening a
Book block spine formed from compressed individual printed sheets
according to the preamble of
Bei der Verarbeitung von Buchblöcken zum Klebebinden aus wenigstens
einfach gefalteten Druckbogen werden letztere nach
dem Zusammentragen in eine Klemmvorrichtung eines Klebebinders
überführt, in der sie anschliessend Bearbeitungsstationen passieren.
Dabei werden die in Falznähe zu einem Buchlockrücken zusammengepressten
Druckbogen durch spanendes Abtrennen von den Falzen
befreit. Dies geschieht beispielsweise bei Klebebindern von
Müller Martini durch ein um eine senkrechte Achse rotierendes
Kreismesser, welches eine relativ glatte Rückenfläche hinterlässt,
die anschliessend, je nach Qualität des zu verarbeitenden
Papieres, entsprechend aufgerauht werden muss, um eine
günstige Verbindung der Oberfläche des Buchblockrückens mit
dem verwendeten Klebstoff herstellen zu können.In the processing of book blocks for perfect binding from at least single folded printed sheets, the latter are transferred after being gathered into a clamping device of a perfect binder, in which they then pass through processing stations.
The printed sheets pressed together in the vicinity of the fold to form a booklock spine are freed from the folds by cutting. For example, in the case of perfect binders from Muller Martini, this is done by a circular knife rotating around a vertical axis, which leaves a relatively smooth back surface, which then has to be roughened, depending on the quality of the paper to be processed, in order to ensure a favorable connection between the surface of the book block spine and the to be able to produce used adhesive.
Es werden aber auch Fräswerkzeuge zum Entfernen der Falze eingesetzt.Milling tools are also used to remove the folds.
Beim anschliessenden Aufrauhen der Blattkanten resp. des beschnittenen
Buchblockrückens werden aus Karbiden gebildete
Schleifmittel verwendet.
Der Einsatz von Karborundumbelägen erfolgt gemäss "Technologie
der Klebebindung", Alfred Furler, u.a. mit einem um eine senkrechte
Achse rotierenden Teller, über den die Buchblöcke hinweggeführt
werden.When roughening the sheet edges respectively. of the trimmed book block spine, abrasives formed from carbides are used.
Carborundum coverings are used according to "Perfect Binding Technology", Alfred Furler, including a plate rotating around a vertical axis over which the book blocks are guided.
Durch den anfallenden Schleifstaub verstopfen die Freiräume der Karborundumbeläge zwischen dem Schleifkorn und es entsteht eine Neigung zum Verschluss des Aufrauhwerkzeuges, der sich auch auf die Blattkanten überträgt.The free space clogged by the grinding dust of the carborundum coverings between the abrasive grain and it is created an inclination to lock the roughening tool also transfers to the sheet edges.
Die CH-A-676'344 beschreibt und zeigt eine Vorrichtung der eingangs beschriebenen Art. Diese Druckschrift würdigt einen bekannten Kerbwerkzeuge aufweisenden Werkzeugträger, dessen Drehachse in der Fortbewegungsrichtung eines Buchblocks so geneigt ist, dass der Buchblockrücken während einer Vorwärtsbewegung nur ein Segment des Drehkreises der Schneidwerkzeuge schneidet. Damit wird erreicht, dass die Kerbwerkzeuge nur von einer Seite in den Buchrücken einschneiden.CH-A-676'344 describes and shows an apparatus of type described in the introduction known notch tools having tool carrier, the Axis of rotation in the direction of travel of a book block so is inclined that the book block spine during a forward movement only one segment of the turning circle of the cutting tools cuts. This ensures that the notching tools only from cut one side into the spine.
Aufgabe der Erfindung ist es somit, eine Vorrichtung zum Aufrauhen von rückenseitig beschnittenen Buchblöcken zu schaffen, mit welcher Papierfasern an den Blattkanten freigelegt resp. Füllstoffe herausgehoben werden können, um die mit dem Klebstoff zu verbindende Oberfläche des Buchblockrückens zu optimieren.The object of the invention is therefore a device for roughening creating blocks of book trimmed on the back, with which paper fibers are exposed on the sheet edges resp. Fillers can be lifted out with the glue optimize the surface of the book block spine to be connected.
Erfindungsgemäss wird diese Aufgabe nach dem Kennzeichen des
Patentanspruches 1 gelöst.
Dadurch kann ein wirkungsvollerer Aufrauheffekt an dem Buchblockrücken
als beispielsweise durch das Verfahren und die
Vorrichtung nach der WO 91/06435 erzielt werden.
Daraus erfolgt, dass der den Anstellwinkel α bestimmende
Winkel zwischen Fortbewegungsrichtung und Drehachse in
Fortbewegungsrichtung F betrachtet grösser als 90° ist. According to the invention, this object is achieved according to the characterizing part of
As a result, a more effective roughening effect on the book block spine can be achieved than, for example, by the method and the device according to WO 91/06435.
It follows from this that the angle determining the angle of attack α between the direction of travel and the axis of rotation in the direction of travel F is greater than 90 °.
Da eine weitgehend gleichmässig ebene Rückenfläche gewünscht
ist, ist der Anstellwinkel α mit Rücksicht auf den Durchmesser
des Aufrauhwerkzeuges entsprechend einzuhalten.
Durch die nachwirkende, tiefere Aufrauhbewegung werden die von
den vorlaufenden Bearbeitungskanten seitlich verlegten Blattkanten
wieder in die ursprüngliche Lage zurückversetzt und
dabei leicht aufgefächert, wodurch die Klebeverbindung weiter
begünstigt wird.Since a largely even back surface is desired, the angle of attack α must be observed accordingly, taking into account the diameter of the roughening tool.
Due to the deeper roughening action, the sheet edges laid laterally by the leading processing edges are returned to their original position and slightly fanned out, which further promotes the adhesive bond.
Vorteilhaft sind die Bearbeitungskanten des Aufrauhwerkzeuges am Umfang eines kreisförmigen Halters angeordnet, wodurch eine regelmässige Verteilung der Markierungen am Buchblockrücken entstehen kann.The processing edges of the roughening tool are advantageous arranged on the circumference of a circular holder, whereby a regular distribution of the markings on the spine of the book block can arise.
Als geeignete Bearbeitungskanten erweisen sich Schneidelemente, die durch einen erzielbaren Schneideffekt eine schonende Behandlung der Blattkanten beim Freilegen von Papierfasern und/oder Ausheben von Füllstoffen gestatten.Cutting elements have proven to be suitable processing edges, which is gentle due to the cutting effect that can be achieved Treatment of the sheet edges when exposing paper fibers and / or allow fillers to be excavated.
Eine Optimierung der Oberfläche des Buchblockrückens kann dadurch erreicht werden, wenn die Umfangsgeschwindigkeit der Bearbeitungskanten in Abstimmung mit der Fortbewegungsgeschwindigkeit eines Buchblockes so gewählt wird, dass sich die kreisförmigen Markierungen überschneiden.This can optimize the surface of the book block spine be achieved when the peripheral speed of the Machining edges in coordination with the speed of travel of a book block is chosen so that intersect the circular marks.
