Die Profilkörper sind vorteilhafterweise jeweils mit Ausnehmungen versehen, durch welche die Seitenbereiche der Druckformen umfaßt werden und die somit als Führung dienen. Die Ausnehmungen können in den Profilkörpern mäanderförmig - vorzugsweise S-förmig-verlaufen, so daß den jeweils aufzunehmenden Druckformen eine versteifende Verformung aufgeprägt wird, die sie gegen Vibrationen am Druckwerk unempfindlicher macht und durch welche die seitliche Führung in den Ausnehmungen ermöglicht wird.In a further embodiment of the solution according to the invention the profile body both stationary on the side walls of the Printing unit as well as pivotable on the side walls be included. The profile bodies are advantageous each provided with recesses through which the Side areas of the printing forms are included and thus serve as a guide. The recesses can be in the Profile bodies meandering - preferably S-shaped, so that each of the printing forms to be included stiffening deformation is imprinted against it Vibrations on the printing unit less sensitive and through which enables lateral guidance in the recesses becomes.

Die Profilkörper umfassen ferner Antriebseinheiten und zwar jeweils für die zuzuführende erste Druckform, wie für die zu entnehmende zweite Druckform. Die Antriebseinheiten - beispielsweise kompakte Elektromotoren mit Friktionsrollen - arbeiten mit Stützelementen zusammen, so daß die Seitenbereiche beidseits der Druckformen reibschlüssig gefördert werden können. Die erwähnten Stützelemente können sowohl als Rollen oder auch bänderförmig ausgeführt sein. Im Bereich der Antriebseinheiten an den jeweiligen Ausnehmungen am Profilkörper werden die Seitenbereiche geführt. The profile body also include drive units, namely each for the first printing form to be fed, as for the taking second printing form. The drive units - For example with compact electric motors Friction rollers - work together with support elements, so that the side areas on both sides of the printing forms can be promoted frictionally. The mentioned Supporting elements can be in the form of rolls or ribbon-like be executed. In the area of the drive units at the respective recesses on the profile body Side areas led.

Diese Profilkörper 9 enthalten jeweils mindestens eine erste Druckform 4 - die neu auf einen Druckformzylinder 3 des Druckwerkes 1 aufgebracht wird-sowie mindestens eine zweite Druckform 5, die zuvor vom Druckformzylinder 3 abgenommen worden ist. Die Druckformen 4 und 5 weisen jeweils Druckformvorderkanten 7 sowie Druckformhinterkanten 8 auf, die in Klemmeinrichtungen auf dem Umfang des Druckformzylinders 3 eingeführt werden und die Druckformen 4 bzw. 5 auf dem Umfang des Druckformzylinders 3 fixieren. Die Seitenbereiche 6 (siehe Fig. 2) der Druckformen werden in Profilen 10, 11 an oder innerhalb der Profilkörper 9 geführt. Die Profile 10, 11 zur Aufnahme der Seitenbereiche 6 der Druckformen 4, 5 sind als Ausnehmungen 12, 13 ausgeführt, die mäanderförmig gekrümmt an oder innerhalb der Profilkörper 9 verlaufen. Vorzugsweise weisen die Ausnehmungen eine S-förmige Krümmung auf. Mittels der den Druckformen 4 und 5 durch die Ausnehmungen 12, 13 aufgeprägte Krümmung werden die Druckformen 4, 5 derart versteift, daß deren Führung nur an den Seitenbereichen 6 völlig ausreichend ist. Daher sind keine Führungshilfen notwendig, die auf die druckende Oberfläche der Druckformen 4 und 5 einwirken, wodurch die Beschädigungsgefahr der empfindlichen Oberflächen drastisch gemindert wird.On the two side walls 2 of a printing unit 1 are each Profile body 9 attached. This profile body 9 included in each case at least one first printing form 4 - the new one Printing form cylinder 3 of the printing unit 1 is applied as well at least one second printing form 5, previously from Printing form cylinder 3 has been removed. The printing forms 4 and 5 each have printing form leading edges 7 and Printing form trailing edges 8 on, in clamping devices the scope of the printing form cylinder 3 are introduced and the Printing forms 4 and 5 on the circumference of the printing form cylinder 3 fix. The side areas 6 (see FIG. 2) of the printing forms are in profiles 10, 11 on or within the Profile body 9 out. The profiles 10, 11 for receiving the Side areas 6 of the printing forms 4, 5 are as Recesses 12, 13 executed, which are curved in a meandering shape or run within the profile body 9. Preferably the recesses have an S-shaped curvature. Means the printing plates 4 and 5 through the recesses 12, 13th imprinted curvature, the printing forms 4, 5 are such stiffens that their guidance only on the side areas 6 is completely sufficient. Therefore, they are not guides necessary on the printing surface of the printing plates 4 and 5 act, reducing the risk of damage to the sensitive surfaces is drastically reduced.

An den Profilen 10, 11 der Profilkörper 9 sind Antriebseinheiten 14 vorgesehen. Diese Antriebseinheiten 14 arbeiten mit Stützelementen 15 zusammen, die im Ausführungsbeispiel als Rollen dargestellt sind. Bänder oder Kunststoffketten wären ebenfalls denkbar.On the profiles 10, 11 of the profile body 9 are Drive units 14 are provided.

Aus Symmetriegründen ist nur eine Hälfte des Druckwerkes bis zur Maschinenmitte 16 gezeigt. Die Friktionsrollen 14.1 arbeiten mit Stützelementen 15 zusammen, die unterhalb der Friktionsrolle 14.1 vorgesehen sind. Die Friktionsrolle 14.1 und das Stützelement 15 ergreifen den Seitenbereich 6 der Druckform 4 beidseitig und fördern die Druckform 4 auf den Umfang des hier nicht dargestellten Druckformzylinders 3. Um einen einwandfreien Transport der Druckformen 4, 5 - also der zuzuführenden wie der zu entnehmenden Druckform - zu gewährleisten, ist der gezeigten Antriebseinheit 14 eine entsprechende an der - hier nicht gezeigten-gegenüberliegenden Seitenwand 2 des Druckwerkes zugeordnet. On the profile bodies 9, which are connected by a fastening 17 to the respective side wall can be connected, but also could be pivotable, there are the drives 14, include the friction rollers 14.1. For reasons of symmetry only half of the printing unit to the middle of the press 16 shown. The friction rollers 14.1 work with Support elements 15 together, which are below the Friction roller 14.1 are provided. The friction roller 14.1 and the support element 15 grip the side region 6 of the Printing form 4 on both sides and promote the printing form 4 on the Scope of the printing form cylinder, not shown here 3. Um proper transport of the printing forms 4, 5 - that is to be fed as well as the printing form to be removed ensure, the drive unit 14 shown is a corresponding on the opposite - not shown here Associated side wall 2 of the printing unit.

Jeder sich in den Profilkörper 9 erstreckenden Ausnehmung 12, 13 ist mindestens eine Antriebseinheit 14 zugeordnet. Es können durchaus auch mehrere Antriebseinheiten 14 entlang des Förderpfades der jeweiligen Druckformen 4 und 5 vorgesehen sein. Es kann dahingestellt bleiben, ob die Ausnehmungen 12, 13 unmittelbar in den Profilkörpern 9 vorgesehen sind, oder ob separate U-förmige Profile an den Profilkörpern 9 befestigt werden können. Die in Fig. 2 dargestellten Antriebseinheiten 14 befinden sich ebenfalls entlang des Förderpfades für die zweite, die zu entnehmende Druckform 5, auch wenn dies in Fig. 2 nicht dargestellt ist. Durch die dargestellten Friktionsrollen 14.1, die mit dem Stützelement 15 zusammenwirken, lassen sich die Bereiche 6 der Druckformen 4, 5 etwa mittig in den Querschnitt der Ausnehmungen 12, 13 führen, so daß ein Schleifen auf den Oberflächen der Ausnehmungen 12, 13 wirksam verhindert werden kann. Each extending into the profile body 9 Recess 12, 13 is at least one drive unit 14 assigned. There can be several Drive units 14 along the conveying path of the respective Printing forms 4 and 5 may be provided. It can be left open remain whether the recesses 12, 13 directly in the Profile bodies 9 are provided, or whether separate U-shaped Profiles can be attached to the profile bodies 9.
