Abstract
Description
Formzylinder für Tiefdrück mit einer magnetisch aufgespanntenForm cylinder for gravure printing with a magnetically clamped
Wiokelplatt e Die Erfindung betrifft einen Formzylinder für Tiefdruck mit einer magnetisch aufgespannten und damit von ihrer Rückseite her auf dem Zylinder festgehaltenen Wickelplatte, Solche ';ickelplatten haben den Vorzug einer einfachen und billigen Pertigung sowie leichter Handhabung. Wiokelplatte e The invention relates to a forme cylinder for gravure printing with a magnetically stretched one and thus on the cylinder from its rear side Fixed winding plate, such '; ickelplatten have the advantage of a simple one and cheap production as well as easy handling.
Der Erfindung liegt die Aufgabe zugrunde, den zum Einhängen der Plattenenden notwendigen Spalt an der Zylinderaußenseite zuverlässig zu verschließen, so daß der Verschluß auch gegen die Farblösungsmittel (Toluol) beständig ist, ferner so zu verschließen, daß die Rakel ungestört arbeiten kann und daß ein Plattenwechsel leicht und schnell durchführbar ist. The invention is based on the object of hanging the plate ends to close the necessary gap on the outside of the cylinder reliably, so that the closure is also resistant to the color solvents (toluene), furthermore so to close that the squeegee can work undisturbed and that a plate change can be carried out easily and quickly.
Die Erfindung löst diese Aufgabe durch die im Patentanspruch gekennzeichneten herkmal e. Ihre Wirkungsweise spricht für sich selbst. Die Anwendung der alternativ vorgeschlagenen Hohlkehle erfordert eine zur Langsachse verschränkte Lage der Rakel, die in ihrer Gesamtlänge die 3reite der Hohlkehle in Umfangerichtung wenigstens überdeckt. Damit die Rakel bei größeren Zylinderlängen nicht zu schräg gestellt werden qiuß, womit sie in ihrer Punktion behindert wäre, was also bei mehreren Atzungen nebeneinander erforderlich wird, wird die Rakel in Ätzungsbreiten geteilt. Die hohlkehle hat als besonderen Vorteil, daß weiche fließende Übergänge an ihren Längsrandkanten angebracht werden können, welche auch die Platten-Abkantungen entschärfen helfen. Damit bei einer Hohlkehle die Rakel nicht an den Zylinderstirnseiten nicht in die Hohlkehle einfallen kann, ist eine Anordnung eines geschlossenen Führungsringes an den beiden Zylinderstirnseiten mit der mit der Zylindermanteloberfläche flucht enden hußenringfläche vorgesehen.The invention solves this problem by the feature e characterized in patent claim. Their mode of action speaks for itself. The use of the alternatively proposed fillet requires a position of the doctor blade that is crossed relative to the longitudinal axis and that at least covers the width of the fillet in the circumferential direction in its overall length. So that the squeegee does not have to be placed too obliquely in the case of larger cylinder lengths, which would hinder its puncture, which is the case with several etchings next to one another is required, the squeegee is divided into etching widths. The particular advantage of the fillet is that soft, flowing transitions can be made on its longitudinal edges, which also help to defuse the panel folds. In order to prevent the squeegee from falling into the groove at the cylinder end faces in the case of a fillet, a closed guide ring is provided on the two cylinder end faces with the sleeve ring surface that ends flush with the cylinder jacket surface.
Zu Zwecken eines leichten und schnellen Plattenwechsels kann gemäß der Erfindung in die Füllung einer geraden Einhängenut eine Reißschiene oder ein Reißdraht eingebettet sein. Für eine hinterschnittene Nut kann gemäß der Ereindung auf derem Grund eine Hubwerksleiste angeordnet und dort heb- und senkbar sein. im abgesenkten Zustand wird wenigstens das Wickelplattenende hihter der hinterschnittenen Nutkante sofort freigelegt. For the purpose of quick and easy plate changing, according to of the invention in the filling of a straight hanging groove a tear bar or a Be embedded tear wire. For an undercut groove, according to the construction on the bottom of which a hoist bar is arranged and can be raised and lowered there. in the In the lowered state, at least the end of the winding plate is higher than the undercut Groove edge exposed immediately.
Verschiedene Ausführungen der Erfindung sind in der Zeichnung schematisch dargestellt. Es zeigt Fig. 1 den perspektivischen Ausschnitt eines Formzylinders 1 mit einer geraden Längsnut 2, Fig. 2 die Stirnansicht zu Fig.1 mit eingelegten und durch biagnetkraft festgehaltenen Platten 3,4, Fig. 3 das Binspritzen der Nutfüllung 5 in den durch einen angedrückten Formbalken 6 abgedeckten Nuthohlraum, von der Stirnseite her, Fig. 4 eine Ausführung ähnlich Fig.3, jedoch mit einer durch Abrollen eingedrückten Hohlkehle 7, womit zugleich die Abkantungen 8 der Viickelplatten 3,4 entschärft sind, Fig. 5 eine Ausführung ähnlich Fig.3, jedoch mit in die Nutfüllung 5 eingebetteter Reißschiene 14, die auch ein Reißdraht sein kann, Fig. 6 eine Ausführung mit hinterschnittener Nut 9, auf derem Grund eine Hubwerksleiste 10 bei 11 an einen Exzenter 12 angelenkt ist, der bei Drehen um die Achse 13 die Hubwerkeleite 10 zwangsweise heben oder senken läßt Fig. 7 eine Stirnansicht eines Druckwerks mit Farbwerk 15 und Gegendruckzylinder 16, dessen Umfang die Hälfte (oder ein ganzes Vielfaches) des Formzylinders 1 beträgt und mit diesem in formschliissiger Verbsindung steht (zOBO durch Zahnräder), so daß ein auf dem Gegendruckzylinder 16 eingefraster Kanal 17 stets über dem Sormgrlinderkanal 2 abrollt, Die Rakel ist mit 18, eine Sinfärbewalze mit 19 bezeichnet. Various embodiments of the invention are shown schematically in the drawing shown. It shows Fig. 1 the perspective detail of a forme cylinder 1 with a straight longitudinal groove 2, FIG. 2 shows the end view of FIG. 1 with inserted and plates 3, 4, Fig. 3 held in place by biagnetic force, the injection molding of the groove filling 5 into the groove cavity covered by a pressed-on form bar 6, of which Front side, FIG. 4 shows an embodiment similar to FIG. 3, but with one by rolling indented groove 7, with which at the same time the bevels 8 of the Viickelplatten 3,4 are defused, Fig. 5 shows an embodiment similar to Fig.3, but with the groove filling 5 embedded tear bar 14, which can also be a tear wire, FIG. 6 shows an embodiment with undercut groove 9, on the bottom of which a hoist bar 10 at 11 to one Eccentric 12 is articulated which, when rotating about axis 13, forces the lifting mechanism 10 7 shows an end view of a printing unit with inking unit 15 and impression cylinder 16, the circumference of which is half (or a whole multiple) of the forme cylinder 1 and is in a form-fitting connection with it (zOBO through gears), so that a channel cut into the impression cylinder 16 17 always rolls over the Sormgrlinderkanal 2, the squeegee is 18, a Sinfärewalze labeled 19.
