Ebenso ist in den F i g. 1 und 2 die Befestigungsvorrichtung nur für ein Druckplattenende, nämlich der genau gegenüber dem Plattenzylinder einzujustierende »Druckanfang«, dargestellt. Das andere Druckplattenende, das ^Druckende«, kann durch jede konventionelle Vorrichtung befestigt werden. Das Ende der Druckplatte 4 weist Ausnehmungen 5 auf, die zur Anlage mit an der Spannschiene 3 befestigten Bolzen 6 gebracht werden können, wodurch die Lage der Platte 4 zur Spannschiene 3 festgelegt ist. Die Platte 4 wird darauf durch eine Klemmschiene 7 auf der Spannschiene 3 festgeklemmt. Zu diesem Zweck werden die in die Spannschiene 3 einschraubbaren und mit Innensechskant versehenen Schrauben 8 angezogen. A tensioning rail 3 is arranged in the channel 1 of a plate cylinder 2 of a sheet-fed printing press. F i g. 2 shows only one end of the tensioning rail, the other end of the tensioning rail 3 is symmetrical and is therefore not shown. Likewise, in FIGS. 1 and 2 the fastener only for a printing plate end, namely the "printing start" to be adjusted exactly in relation to the plate cylinder, shown. The other end of the printing plate, the "printing end", can be effected by any conventional device be attached. The end of the pressure plate 4 has recesses 5, which for the plant can be brought with fastened to the tensioning rail 3 bolts 6, whereby the location of the Plate 4 is set to the tensioning rail 3. The plate 4 is thereupon by a clamping rail 7 on the Clamping rail 3 clamped. For this purpose, the can be screwed into the tensioning rail 3 and hexagon socket screws 8 tightened.
Die Spannschiene 3 ist auf im Zylinderkanal 1 verschraubten Schienen 9 sowohl in Achs- als auch in Umfangsrichtung des Plattenzylinders 2 verschiebbar gelagert. Die Verschiebung der Spannschiene 3 in Zylinderachsrichtung erfolgt durch Verdrehen von in die Spannschiene einschraubbaren Schrauben 10: die Verschiebung der Spannschiene 3 in Zylinderumfangsrichtung erfolgt durch die Schrauben 11, wobei Druckfedern 12, die in Bohrungen 13 der Spannschiene 3 geführt sind und sich einerseits auf der Spannschiene 3 und andererseits auf am Plattenzylinder 2 befestigten Böcken 14 abstützen, die Spannschiene 3 nach links (F i g. 2), d. h. in eine die Druckplatte entspannende Richtung, zu drücken bestrebt sind.The tensioning rail 3 is on rails 9 screwed into the cylinder channel 1 both in the axial and in the axial direction The circumferential direction of the plate cylinder 2 is slidably supported. The shift of the tensioning rail 3 in The cylinder axis direction is achieved by turning screws 10 that can be screwed into the tensioning rail: the The tensioning rail 3 is displaced in the circumferential direction of the cylinder by means of the screws 11, wherein Compression springs 12, which are guided in bores 13 of the tensioning rail 3 and on the one hand on the Support the tensioning rail 3 and, on the other hand, on brackets 14 attached to the plate cylinder 2, the tensioning rail 3 to the left (Fig. 2), i.e. H. tends to push in a direction relaxing the pressure plate are.
An den Enden der Spannschiene 3 (s. auch F i g. 4) sind Winkeleisen 15, 16 angeschraubt. (Langlöcher 17 (F i g. 2) ermöglichen geringfügige Verschiebungen der Winkeleisen 15, 16 in Zylinderachsrichtung. Im Zylinderkanal 1 sind Winkeleisen 19, 20 festgeschraubt, die in Langlöchern 21 geringfügig in Zylinderumfangsrichtung verschiebbar sind. Das Winkeleisen 15 hat bearbeitete, in einem rechten Winkel zueinander stehende Ausrichtflächen 23, 24, denen Ausrichtflächen 25. 26 am Winkeleisen 19 entsprechen. Angle irons 15, 16 are screwed onto the ends of the tensioning rail 3 (see also FIG. 4). (Elongated holes 17 (F i g. 2) allow slight displacements of the angle irons 15, 16 in the direction of the cylinder axis. in the Cylinder channel 1, angle irons 19, 20 are screwed tightly in elongated holes 21 slightly in the circumferential direction of the cylinder are movable. The angle iron 15 has been machined at a right angle Alignment surfaces 23, 24 standing relative to one another, to which alignment surfaces 25, 26 on the angle iron 19 correspond.
