Als interner Stand der Technik ist ein Farbwerk gemäß dem Oberbegriff des Anspruchs 1 zum Einfärben einer halbzylinderbreiten Druckplatte für sog. Panoramadruck, sowie mindestens einer viertelzylinderbreiten Druckplatte mit Drucksätzen maximal möglicher Breite und minimal möglichen farbfreien Zonen zwischen dem Drucksätzen unmittelbar benachbarter Druckplatten bekannt. Das Farbwerk besteht aus einem Farbwerkwalzenzug der mit einem Farbduktor beginnt und unter Zwischenschaltung von Farbübertragungswalzen und changierenden zylinderlangen Farbreibzylinder bei einer oder mehreren Farbauftragswalzen endet. Der Farbduktor hat hierbei einen oder mehrere Einstiche in Form von Ringnuten. Diese Einstiche fluchten zu den Einstichen dem Farbduktor nachgeschalteten Farbübertragungswalzen. Die Farbreibzylinder weisen keinerlei Einstiche auf. Durch die gleiche Lage der Einstiche der einzelnen Walzen im Farbwalzenzug ist es möglich, ohne ein Ineinanderlaufen der benachbarten Druckfarben die Panoramadruckplatte und die neben ihr angeordneten viertelzylinderbreiten Druckplatten einzufärben. Soll nun von Panoramadruck auf Druck von viertelzylinderbreiten Druckplatten umgestellt werden, so müssen die auf Panoramadruck-Verhältnisse eingestochene Farbübertragungswalzen gegen solche zum Druck von viertelzylinderbreiten Druckplatten geeignete ausgetauscht werden. In der Praxis bedeutet das, daß jeweils ein eingestochener Farbübertragungswalzensatz für Panoramadruck und ein weiterer für viertelzylinderbreiten Druck vorhanden sein muß.An inking unit is in accordance with the state of the art the preamble of claim 1 Coloring a half-cylinder-wide printing plate for so-called Panorama print, as well as at least one quarter-cylinder-wide printing plate with printing sets maximum possible width and minimum possible color-free zones between the printing sets immediately neighboring printing plates known. The inking unit consists of an inking roller with a Color duct begins and with the interposition of Ink transfer rollers and iridescent cylinder lengths Ink rubbing cylinder in one or more Ink application roller ends. The color duct has here one or more punctures in the form of ring grooves. These punctures are aligned with the punctures Ink duct roller downstream of the ink roller. The Ink rubbing cylinders have no punctures. By the same position of the punctures of the individual rollers in the Inking roller it is possible without running into each other the neighboring printing inks the panorama printing plate and the quarter cylinder widths next to it Color printing plates. Should now go from panorama print to Printing of quarter-cylinder-wide printing plates changed must be based on panoramic printing conditions stabbed ink transfer rollers against those for Printing of quarter-cylinder-wide printing plates be replaced. In practice this means that one set of ink transfer rollers for panorama printing and another for quarter-cylinder pressure must be available.

Ein insgesamt mit 1 bezeichnetes Farbwerk einer Rollenrotationsdruckmaschine besitzt einen Farbduktor 2, der vier nebeneinanderliegende, ringförmige Mantelflächen 3, 4, 6, 7 aufweist, die durch Einstiche oder Ringnuten 8, 9, 10 mit jeweils einer Breite a voneinander getrennt sind. Jeder Mantelfläche 3, 4, 6, 7 ist jeweils ein viertelzylinderbreiter nicht dargestellter Farbkasten zugeordnet, deren Trennschilde formschlüssig in die Ringnuten 8, 9, 10 eingreifen und somit die einzelnen Farbkästen voneinander trennen. An den Farbduktor 2 schließt sich eine Filmwalze 12 an, die wiederum über eine Farbübertragungswalze 13 mit einem Farbreibzylinder 14 verbunden ist. Eine weitere Farbübertragungswalze 16 ist zwischen dem Farbreibzylinder 14 und einem zweiten Farbreibzylinder 17 angeordnet, der wiederum über zwei erfindungsgemäße, parallel zueinander verlaufende Farbauftragswalzen 18, 19 mit einem Plattenzylinder 21 umfangsmäßig in Verbindung steht, der wiederum mit einem nicht dargestellten Gummituch- oder Druckzylinder zusammenwirkt.
Die Filmwalze 12 weist eine ununterbrochene Mantelfläche auf, desgleichen die in axialer Richtung hin- und herbewegbaren Farbreibzylinder 14, 17. Die mit den Farbreibzylindern 14, 17 zusammenwirkenden Farbübertragungswalzen 13, 16 weisen jeweils in ihrer Mantelfläche Ringnuten 22, 23, 24 mit einer Breite a auf, die die gesamte Mantelfläche in vier nebeneinanderliegende, gleichgroße, ringförmige Mantelflächen 26, 27, 28, 29 trennt. Der Plattenzylinder 21 trägt auf seinem Umfang drei Druckplatten 31, 32, 33, von denen die ersten beiden Druckplatten 31, 32 jeweils etwa einer viertel Zylinderbreite entsprechen und eine maximale Druckbreite B aufweisen. Die dritte Druckplatte 33 ist für einen etwa eine halbe Zylinderbreite einnehmenden Panoramadruck mit einer maximalen Druckbreite C vorgesehen. Zwischen den Druckplatten 31, 32, 33 besteht eine um den Zylinderumfang herumlaufende, ringförmige farbfreie Zone 34, 36, jeweils mit der Breite d, die durch Fluchtlinien 87, 88 begrenzt sind. Die Fluchtlinien 87, 88 verlaufen innerhalb des Bereiches a des Farbduktors 2 bzw. der Farbübertragungswalzen 13, 16. Die beiden zwischen dem Farbreibzylinder 17 und dem Plattenzylinder 21 parallel zueinander verlaufenden Farbauftragswalzen 18, 19 weisen jeweils an ihrem Umfang zwei Ringnuten 37, 38 auf, analog der Anzahl der farbfreien Zonen 34, 36 auf dem Plattenzylinder 21. Die Ringnuten 37, 38 trennen jeweils Mantelflächen 39, 41, 42 der Farbauftragswalzen 18, 19 voneinander, deren Breite L, M wenig größer (Differenz d-e) ist als die Breite B, C der Druckplatten 31, 32, 33, also etwa einer Viertelzylinderbreite L bzw. einer halben Zylinderbreite M entsprechen. Die Ringnuten 37, 38 weisen eine Breite e auf, die geringer ist als die Breite d der farbfreien Zonen 34, 36 auf dem Plattenzylinder 21. Demzufolge ist die Breite L, M der Mantelflächen 39, 41, 42 jeweils um die Differenz d-e größer als die Druckbreite B, C der Druckplatte 31, 32, 33. Die genannten Walzen bzw. Zylinder 2, 12, 14, 17, 21 sind seitengestellfest gelagert, die Walzen 13, 16, 18, 19 sind in gestellfest angelenkten Lagerarmen angeordnet. Die in Lagerarmen angeordneten Walzen 13, 16, 18, 19 werden über ihre Mantelfläche von den vorgenannten Walzen bzw. Zylindern 2, 12, 14, 17, 21 reibschlüssig angetrieben.An inking unit of a web-fed rotary printing press, designated as a whole by 1, has an inking unit 2, which has four adjacent, annular outer surfaces 3, 4, 6, 7, which are separated from one another by punctures or annular grooves 8, 9, 10, each with a width a. Each lateral surface 3, 4, 6, 7 is assigned a quarter-cylinder-wide ink fountain (not shown), the separating plates of which engage positively in the ring grooves 8, 9, 10 and thus separate the individual ink fountains from one another. A film roller 12 connects to the ink fountain roller 2, which is in turn connected to an ink rubbing cylinder 14 via an ink transfer roller 13. Another ink transfer roller 16 is arranged between the ink rubbing cylinder 14 and a second ink rubbing cylinder 17, which in turn is circumferentially connected via two ink application rollers 18, 19 according to the invention, which run parallel to one another, with a plate cylinder 21, which in turn interacts with a blanket or printing cylinder, not shown.
The film roller 12 has an uninterrupted outer surface, as do the ink rubbing cylinders 14, 17 which can be moved back and forth in the axial direction. The ink transfer rollers 13, 16 cooperating with the ink rubbing cylinders 14, 17 each have annular grooves 22, 23, 24 with a width a in their outer surface on, which separates the entire outer surface into four adjacent, equal-sized, annular outer surfaces 26, 27, 28, 29. The plate cylinder 21 carries three pressure plates 31, 32, 33 on its circumference, of which the first two pressure plates 31, 32 each correspond to approximately a quarter cylinder width and have a maximum printing width B. The third printing plate 33 is provided for a panorama print with a maximum printing width C that takes up about half a cylinder width. Between the pressure plates 31, 32, 33 there is an annular color-free zone 34, 36 running around the cylinder circumference, each with the width d, which are delimited by alignment lines 87, 88. The alignment lines 87, 88 run within the area a of the ink duct 2 or the ink transfer rollers 13, 16. The two ink application rollers 18, 19 running parallel to one another between the ink rubbing cylinder 17 and the plate cylinder 21 each have two ring grooves 37, 38 on their circumference, analogous to the number of ink-free zones 34, 36 on the plate cylinder 21. The annular grooves 37, 38 each separate lateral surfaces 39, 41, 42 of the inking rollers 18, 19, the width L, M of which is slightly larger (difference de) than the width B. , C correspond to the pressure plates 31, 32, 33, that is to say approximately a quarter cylinder width L or half a cylinder width M. The annular grooves 37, 38 have a width e which is less than the width d of the color-free zones 34, 36 on the plate cylinder 21. Accordingly, the width L, M of the lateral surfaces 39, 41, 42 is greater than the difference de the printing width B, C of the printing plate 31, 32, 33. The rollers or cylinders 2, 12, 14, 17, 21 mentioned are mounted fixed on the side frame, the rollers 13, 16, 18, 19 are arranged in bearing arms articulated on the frame. The rollers 13, 16, 18, 19 arranged in bearing arms are frictionally driven by the aforementioned rollers or cylinders 2, 12, 14, 17, 21 via their outer surface.

Die Funktionsweise des Farbwerkes 1 mit der erfindungsgemäßen Farbwalze 18, 19 ist wie folgt: Von nicht dargestellten Farbkästen werden den vier Mantelflächen 3, 4, 6, 7 des Farbduktors 2 in gleicher Reihenfolge die Druckfarben gelb (diagonal schraffiert), blau (waagerecht schraffiert), zweimal rot (senkrecht schraffiert) zugeführt und über die Filmwalze 12 und Farbübertragungswalze 13 zum in axialer Bewegungsrichtung G changierenden ersten Farbreibzylinder 14 übertragen. Von dort gelangen die Druckfarben über die zweite Farbübertragungswalze 16 zum zweiten Farbreibzylinder 17. Infolge der Changierbewegung des Farbreibzylinders 17 in axialer Richtung G mit einer Hublänge, die der Breite a der Ringnuten 8, 9, 10 des Farbduktors 2 entspricht oder auch der Breite a der Ringnuten 22, 23, 24 der Farbreibzylinder 13, 16, wird jede der auf dem Farbreibzylinder 14 befindlichen Flächen mit den Farben gelb, blau, rot um eine ringförmige Fläche mit der Breite a ergänzt. Fig. 1 zeigt die Farbauftragswalzen 18, 19 sowie den Farbreibzylinder 17 in einer ersten axialen Endstellung auf der linken Seite. Bei der changierenden Hubbewegung G des Farbreibzylinders 17 um den Betrag a nach links, werden die Farbauftragswalzen 18, 19 infolge Reibschluß über die Mantelfläche des Farbreibzylinders 17 um eine Hublänge h mitgenommen, die aus der Differenz zwischen den Breiten d und e resultiert. Dabei bedeutet die Breite d die Breite der ringförmigen farbfreien Zone 34, 36 zwischen den Druckplatten 31, 32, 33 auf dem Plattenzylinder 21 und die Breite e die Breite einer der auf der Farbauftragswalze 18, 19 umlaufenden Ringnuten 37; 38. Demzufolge gilt a > d > e. Fig. 2 zeigt die Farbauftragswalzen 18, 19 sowie den Farbreibzylinder 17 in einer zweiten axialen Endstellung auf der rechten Seite.The functioning of the inking unit 1 with the Ink roller 18, 19 according to the invention is as follows: From Color boxes, not shown, are the four Shell surfaces 3, 4, 6, 7 of the ink duct 2 in the same Order the printing colors yellow (hatched diagonally), blue (hatched horizontally), twice red (vertical hatched) and supplied via the film roller 12 and Ink transfer roller 13 for in the axial direction of movement G iridescent first ink rubbing cylinder 14 transmitted. From there, the printing inks pass through the second Ink transfer roller 16 to the second ink rubbing cylinder 17. As a result of the traversing movement of the ink rubbing cylinder 17 in axial direction G with a stroke length that is the width a corresponds to the ring grooves 8, 9, 10 of the color ductor 2 or also the width a of the annular grooves 22, 23, 24 of the Ink rubbing cylinder 13, 16, each of the on the Ink rubbing cylinder 14 surfaces with the colors yellow, blue, red around an annular surface with the width a supplemented. 1 shows the inking rollers 18, 19 and the color friction cylinder 17 in a first axial End position on the left. With the iridescent Stroke G of the ink cylinder 17 by the amount a to the left, the inking rollers 18, 19 will result Friction over the outer surface of the ink friction cylinder 17 taken along by a stroke length h, which is the difference between widths d and e results.

Fig. 7 zeigt ein Weg-Zeit-Diagramm der axialen Bewegung der erfindungsgemäßen Farbauftragswalze 18, 19 in Verbindung mit dem Farbreibzylinder 17. Eine gestrichelt dargestellte Kurve 91 stellt den Bewegungsablauf einer der Farbauftragswalzen 18, 19 und eine weitere Kurve 92 stellt den Bewegungsablauf des Farbreibzylinders 17 dar. Aus den Kurven 91, 92 ist ersichtlich, daß die Hublänge a des Farbreibzylinders 17, auf der Ordinate des Diagramms von -a/2 bis +a/2 reichend, größer ist als die Hublänge h einer der Farbauftragswalzen 18, 19. Auf der horizontal verlaufenden Zeitachse sind insgesamt vier Hübe t10 bis t40, d. h. Hin- und Herbewegungen des Farbreibzylinders 17 mit den Farbauftragswalzen 18, 19 dargestellt, von denen jedoch nur die Farbauftragswalze 18 genannt wird. Zum Zeitpunkt tNull - linke axiale Endlage des Farbreibzylinders 17 und der Farbauftragswalze 18 nach Fig. 1 und 4 - beginnen sich beide Walzen 17, 18 in Richtung rechter axialer Endlage zu bewegen. Zum Zeitpunkt t1 hat die Farbauftragswalze 18 entsprechend Kurve 91 nach Durchfahren ihrer axialen Hublänge h, d. h. von -h/2 bis +h/2 ihre rechte axiale Endstellung erreicht. Der Farbreibzylinder 17 setzt das Durchlaufen seiner Hubstrecke +a/2 bis zum Zeitpunkt t2 entsprechend der Kurve 92 fort und nimmt die in Fig. 2 und Fig. 5 gezeigte Stellung ein. Zum gleichen Zeitpunkt t2 gibt die Farbauftragswalze 18 ihre Beharrung in der rechten axialen Endstellung nach Fig. 2 auf und wird durch Friktion mit dem Farbreibzylinder 17 in Richtung -h/2 bewegt und hat zum Zeitpunkt t3 nach Absolvierung der Hublänge h ihre linke axiale Endlage nach Fig. 1 erreicht. Der Farbreibzylinder 17 bewegt sich weiter bis zur Absolvierung der Hubstrecke a zum Zeitpunkt t10 entsprechend der Darstellung nach Kurve 92. Somit ist insgesamt ein Hub von den vier im Diagramm nach Fig. 7 dargestellten Hüben absolviert. Die weiteren Hübe t10 / t20, t20 / t30; t30 / t40 verlaufen in analoger Weise. Auf etwa vier Umdrehungen des Plattenzylinders 21 erfolgt jeweils ein Hub, z. B. t0 bis t10 der Walzen 17, 18 in axialer Richtung.FIG. 7 shows a path-time diagram of the axial movement of the inking roller 18, 19 according to the invention in connection with the inking cylinder 17. A curve 91 shown in broken lines represents the movement sequence of one of the inking rollers 18, 19 and a further curve 92 shows the movement sequence of the inking cylinder 17. From curves 91, 92 it can be seen that the stroke length a of the ink-rubbing cylinder 17, which extends from -a / 2 to + a / 2 on the ordinate of the diagram, is greater than the stroke length h of one of the inking rollers 18, 19. A total of four strokes t 10 to t 40 , ie back and forth movements of the ink rubbing cylinder 17 with the ink application rollers 18, 19, are shown on the horizontal time axis, of which only the ink application roller 18 is mentioned. At time t zero - the left axial end position of the inking cylinder 17 and the inking roller 18 according to FIGS. 1 and 4 - both rollers 17, 18 begin to move in the direction of the right axial end position. At the time t 1 , the inking roller 18 has reached its right axial end position according to curve 91 after passing through its axial stroke length h, ie from -h / 2 to + h / 2 . The ink rubbing cylinder 17 continues to travel through its stroke distance + a / 2 until time t 2 in accordance with curve 92 and assumes the position shown in FIGS. 2 and 5. At the same time t 2 , the inking roller 18 gives up its persistence in the right axial end position according to FIG. 2 and is moved by friction with the ink rubbing cylinder 17 in the direction -h / 2 and has its left axial at time t 3 after the stroke length h has been completed End position according to Fig. 1 reached. The ink rubbing cylinder 17 continues to move until the stroke distance a has been completed at the time t 10 in accordance with the representation according to curve 92. Thus, a total of one stroke of the four strokes shown in the diagram in FIG. 7 has been completed. The further strokes t 10 / t 20 , t 20 / t 30 ; t 30 / t 40 run in an analogous manner. At about four revolutions of the plate cylinder 21 there is a stroke, for. B. t 0 to t 10 of the rollers 17, 18 in the axial direction.

Die Farbauftragswalze 18, 19 kann natürlich ausgetauscht werden gegen eine normale Farbauftragswalze ohne Einstiche bzw. Ringnuten, sofern es nicht erforderlich ist, neben einem halbzylinderbreiten Panoramadruck zwei viertelzylinderbreite Drucke maximaler Breite herzustellen. The inking roller 18, 19 can of course be replaced are against a normal inking roller without Punctures or ring grooves, if not necessary is, in addition to a half-cylinder-wide panorama print, two quarter cylinder width prints of maximum width to manufacture.
