Zylindergruben 03; 59 versehen. Jede Zylindergrube 03; 59 trägt an einer jeden in
Produktionsrichtung A des Zylinders 01 weisenden vorderen Kante 04 einen
vorderen oder "vorauslaufenden" Einhängeschenkel 06; 61 der Platte 02; 58. Jede
Platte 02; 58 weist noch einen hinteren oder "nachlaufenden" Einhängeschenkel
07; 62 auf, welcher an einer zweiten hinteren Kante 08 der gleichen Zylindergrube
03; 59 eingehangen ist.A
Ein zwischen der Mantelfläche 11 des Zylinders 01 und der ersten Grubenwand 12

45°. Die zweite, etwa in radialer Richtung des Zylinders 01 verlaufende
Grubenwand 13 weist einen stumpfen Öffnungswinkel Beta von etwa 95° zur
Mantelfläche 11 auf. Beide Kanten 04; 08 oder auch Scheitelpunkte der
Öffnungswinkel Alpha; Beta sind durch einen Befestigungsschlitz 09 getrennt.One between the
Der Befestigungsschlitz 09 ist in seiner lichten Weite b so ausgebildet, daß
nebeneinander zumindest zwei Einhängeschenkel 06, 62 bzw. 07, 61 darin Platz
finden, welche in die Zylindergrube 03; 59 ragen.The
Die Platten 02; 58 können z. B. als biegsame Druckplatten - auch mehrere
nebeneinander liegend - oder als biegsame Trägerplatten mit darauf angeordneten
Gummitüchern ausgebildet sein.The
Die Zylindergrube 03; 59 kann im Querschnitt etwa kreisförmig sein und ist durch
den Befestigungsschlitz 09 mit der Mantelfläche 11 verbunden.The
Jede Zylindergrube 03; 59 nimmt jeweils eine gleich ausgebildete
Klemmvorrichtung 14; 16 auf, welche in einem Basiskörper 19 angeordnet ist. Der
Basiskörper 19 hat die Form eines längsgetrennten Rohres (rinnenförmig), welcher
sich in der Zylindergrube 03; 59 in achsparalleler Richtung erstreckt und mit seiner
Öffnung 31 in Richtung erster Grubenwand 12 bzw. in Richtung Befestigungsschlitz
09 weist.Each
Der rinnenförmige Basiskörper 19 kann im Querschnitt C-förmig oder U-förmig,
rund, oval oder mehreckig ausgebildet sein. Dem Querschnitt des Basiskörpers 19
ist der Querschnitt der Zylindergrube 03 angepaßt.The channel-
Nach einer in Fig. 5 gezeigten Ausführungsvariante ist der Basiskörper 19 in
achsparalleler Richtung in mehrere kürzere Basiskörper 32; 33; 34 unterteilt. Jeder
Basiskörper 32; 33; 34 ist gegenüber dem benachbarten Basiskörper 32; 33; 34
lösbar, z. B. mittels einer Kupplung verbunden. Diese Kupplung kann z. B.
formschlüssig wirken und mittels einer beidendigen Verzahnung 36; 37 der
Basiskörper 32; 33; 34 realisiert werden.According to an embodiment variant shown in FIG. 5, the
Ein freies Ende des sich in der Zylindergrube 03; 59 befindlichen ersten und letzten
Basiskörpers ist drehfest mit einem Endkuppelstück verbunden. Das
Endkuppelstück ist mit seinen die Zylindergrube 03; 59 überdeckenden Teilen
an den Flanken des Zylinders 01 befestigt, z. B. verschraubt.A free end of the in the
Durch die Verwendung von mehreren kurzen Basiskörpern 32 bis 34 kann die
Vorrichtung z. B. zu Wartungszwecken aus der Zylindergrube 03; 59 entnommen
werden, ohne daß dabei der Zylinder 01 aus dem Seitengestell demontiert werden
muß.By using several
In jedem Basiskörper 19 oder 32 bis 34 sind bewegbare Spann- und/oder
Klemmelemente angeordnet, die aus zwei parallel zueinander verlaufenden
Leisten 39; 41 bestehen. Erste oder untere Enden 42; 43 sind in einem lichten
Abstand g, z. B. einem Sechstel oder Achtel des Durchmessers d der
Zylindergrube 03; 59, voneinander in Widerlagern 44 schwenkbar gelagert. Die
Widerlager 44 können aus in dem Basiskörper 19 bzw. jeweils in den Basiskörpern
32 bis 34 angeordneten Schlitzen 45 bestehen, in welche Teile des unteren Endes
42; 43 der Leiste 39; 41 eingreifen.In each
Zweite oder obere einhängeschenkelnahe, etwa rechtwinklig abgekantete Enden
46; 47 (Kraftangriffsenden) der Leisten 39; 41 ragen aus dem Innenraum 29 des
Basiskörpers 19 oder 32 bis 34 heraus und sind direkt oder indirekt mit den jeweils
gegenüberliegenden Einhängeschenkeln 06, 62 bzw. 07, 61 in Wirkverbindung und
drücken diese durch die Kraft von jeweils zumindest einer Feder 48; 49, z. B.
Druckfeder gegen die erste bzw. zweite Grubenwand 12; 13 an. Die Druckfedern
48; 49 sind jeweils zwischen der Innenwand 28 des Basiskörpers 19 und der
Außenseite 51; 52 der Leiste 39; 41 angeordnet.Second or upper ends close to the hanging legs, approximately right-angled ends

Grubenwand 12 abgekanteten Ende 47 der Leiste 41 und der bzw. dem an der
ersten Grubenwand 12 anliegenden Einhängeschenkel 06 bzw. 61 zumindest je
Basiskörper 32 bis 34 ein Wälzkörper, z. B. eine Klemmrolle 53 angeordnet ist.Indirectly in active connection means that between the upper towards the
Die Klemmrolle 53 eines jeden Basiskörpers 32 bis 34 liegt in einer am oberen
einhängeschenkelnahen Ende 46 der Leiste 39 befindlichen Aussparung 54.
Beidseits der Aussparung 54 verbleiben jeweils abgekantete Arme 46 des oberen
Endes 46, welche gegen die zweite Grubenwand 13 bzw. gegen den
Einhängeschenkel 07; 62 drücken (Fig. 1 und 2).The
Zwischen den Innenseiten 55 der Leisten 39; 41 befindet sich ein Luftschlauch 27,
der sich einstückig über die gesamte Länge der Zylindergrube 03 erstreckt. Somit
durchläuft der Luftschlauch 27 den Basiskörper 19 bzw. die Basiskörper 32 bis 34.
Der Luftschlauch 27 ist an einem seiner Enden z. B. mit einem Ventil versehen und
wird über eine damit verbundene, nicht dargestellte Leitung zum Zylinderzapfen

41; 48; 49; 53 werden als Klemm- und/oder Spannelemente bezeichnet. Dies trifft
auch für die kürzeren Basiskörper 32 bis 34 zu.The
Ein Verfahren zum Lösen einer Platte 02 von zwei auf dem Umfang des Zylinders
01 befestigten biegsamen Platten 02; 58 läuft wie folgt ab: Der Luftschlauch 27 der
ersten Klemmvorrichtung 14 wird mit Druckluft von ca. vier bar beaufschlagt.
Dadurch werden die Leisten 39; 41 gegen die Kraft F1; F2 der Federn 48; 49 in
eine erste Freigabestellung X verschwenkt (Fig. 3). Alle Klemmungen werden
aufgehoben. Der hintere Einhängeschenkel 07 der Platte 02 schnellt infolge seiner
Eigenspannung aus dem Befestigungsschlitz 09 heraus. Der vordere
Einhängeschenkel 61 der zweiten Platte 58 ist an der vorderen Kante 04 der
Zylindergrube 03 festgehalten. Der Luftdruck für den Schlauch 27 der
Klemmvorrichtung 14 wird zurückgenommen.A method of detaching a
Nunmehr wird der Luftschlauch 27 der zweiten Klemmvorrichtung 16 mit Druckluft
von ca. zwei bar beaufschlagt. Dadurch wird die Leiste 41 gegen die Kraft F2 der
schwächeren Feder 49 verschwenkt, so daß der vordere Einhängeschenkel 06 der
Platte 02 in einer zweiten Freigabestellung Y freigegeben wird. Der hintere
Einhängeschenkel 62 der zweiten Platte 58 bleibt dabei eingeklemmt, da die Feder
48 mit der größeren Druckkraft F1 dem Druck des Luftschlauches 27 nicht
nachgibt.Now the
Ein Klemmen von Platten 02 oder 58 erfolgt in umgekehrter Reihenfolge.
Es können auch drei und mehr Platten mit der entsprechenden Anzahl von
Klemmvorrichtungen auf dem Zylinder 01 befestigt werden. You can also have three or more plates with the corresponding number of

Claims (5)
- Method of clamping and releasing flexible plates (02; 58) provided with leading, acute-angled and trailing, approximately right-angled hook-in sections (06; 07; 61, 62), employing a hook-in slot (09) and cylinder trench (03; 59) in a cylinder (01) of a rotary printing press, wherein a plurality of plates (02; 58) are solidly clamped on the circumference of the cylinder (01), characterised in that, by actuating a first damping device (14), the rear hook-in section (07) of a first plate (02) is first released at a first releasing position (X) and at the same time the front hook-in section (61) of a second plate (58) is held firm against the front edge (04) of the cylinder trench (03), and in that, by actuating a second clamping device (16), only the clamped-in front hook-in section (06) of the first plate (02) is subsequently released at a second releasing position (Y) and a rear hook-in section (62) of the second plate (58) is held firm by the clamping device (16).
- Method according to claim 1, characterised in that the clamping of the first plate (02) by means of the clamping devices (14; 16) takes place in the reverse order.
- Method according to claim 1, characterised in that the clamping device (14; 16) is actuated by means of a positioning means (27).
- Method according to claim 3, characterised in that the positioning means (27) is in the form of an air tube (27) to which compressed air can be supplied.
- Method according to claim 4, characterised in that the air tube (27) can have two different pressures supplied to it.
