Soll nun die Vorrichtung von der Plattenhalte- oder Ruhestellung (Fig. 1) in die Plattenentnahme- oder Arbeitsstellung (Fig. 2) gebracht werden, so wird der Luftschlauch 33 mit Druckluft beaufschlagt. Dabei liegt eine Widerlagerfläche 36 des Luftschlauches 33 an der Wand 32 der Zylindergrube 03 und eine Kraftangriffsfläche 37 des Luftschlauches 33 am ersten Arm 16 der Profilleiste 14 an. Dadurch erfolgt eine Schwenkbewegung der Profilleiste 14 um das Lager 22; 23, so daß das freie Ende 19 mit dem hinteren Einhängeschenkel 07 und der zweiten Grubenwand 13 außer Eingriff kommt. Weiterhin vergrößert sich der Keilwinkel von Gamma 1 auf Gamma 2 , so daß die Klemmrolle 31 in Richtung Scheitelpunkt des Keilwinkels Gamma 2 rollt (Fig. 2). Dadurch kommt der Umfang der Klemmrolle 31 mit dem vorderen Einhängeschenkel 06 außer Eingriff, welcher bisher an die Grubenwand 12 gedrückt wurde. Die Platte 02 kann entnommen bzw. gewechselt werden. Nach einem Entlüften des Luftschlauches 33 kommen die Teile 19; 31 wieder in Wirkverbindung mit den Einhängeschenkeln 06; 07.Now the device from the plate holding or rest position (Fig. 1) in the Plate removal or working position (Fig. 2) are brought, so the Air hose 33 is pressurized with compressed air. There is an abutment surface 36 of the air hose 33 on the wall 32 of the cylinder pit 03 and one Force application surface 37 of the air hose 33 on the first arm 16 of the profile strip 14 on. This results in a pivoting movement of the profile bar 14 about the bearing 22; 23, so that the free end 19 with the rear suspension leg 07 and second pit wall 13 comes out of engagement. Furthermore, the Wedge angle from gamma 1 to gamma 2, so that the pinch roller 31 in the direction The apex of the wedge angle gamma 2 rolls (Fig. 2). This is where the scope comes from the pinch roller 31 with the front suspension leg 06 disengaged, which has previously been pressed against the pit wall 12. The plate 02 can be removed or be changed. Come after venting the air hose 33 parts 19; 31 again in operative connection with the hanging legs 06; 07th

Nach einer in Fig. 3 gezeigten Ausführungsvariante ist die Profilleiste 14 in achsparalleler Richtung in mehrere kürzere Profilleisten 38; 39 unterteilt. Das Gleiche gilt auch für die Stützleiste 24 welche in mehrere Stützleisten 42; 43 unterteilt ist. Jede Stützleiste 42; 43 ist gegenüber der benachbarten Stützleiste lösbar, z. B. mittels einer Kupplung verbunden. Diese Kupplung kann z. B. formschlüssig wirken und mittels einer beidendigen Verzahnung 46; 47 der Stützleisten 42; 43 realisiert werden. Der Luftschlauch 33 ist immer einstückig ausgebildet und durchläuft die gesamte Zylindergrube 03. Ein freies Ende der sich in der Zylindergrube 03 befindlichen ersten und letzten Stützleiste ist drehfest mit einem Endkuppelstück 48 verbunden. Das Endkuppelstück 48 ist mit seinen die Zylindergrube 03 überdeckenden Teilen an den Flanken des Zylinders 01 befestigt, z. B. verschraubt. According to an embodiment variant shown in FIG. 3, the profile strip 14 is in axially parallel direction in several shorter profile strips 38; 39 divided. The The same also applies to the support strip 24 which is divided into a plurality of support strips 42; 43 is divided. Each support bar 42; 43 is opposite the adjacent support bar releasable, e.g. B. connected by means of a clutch. This clutch can e.g. B. act positively and by means of a double-sided toothing 46; 47 of the Support strips 42; 43 can be realized.
