Embodiment Construction

[0029] The cylinder 01 of the rotary printing machine, such as the plate cylinder 01 or the transfer cylinder 01, has at least one notch 03 facing the inside of the cylinder 01 and extending in the axial direction of the cylinder 01 on its shell surface 02, and the notch is used for Fix at least one lining 04 , for example a printing plate 04 or a blanket 04 . Two bent ends 06, 07, for example the front end 06 and the rear end 07 of one lining 04 with reference to the direction of rotation D, or the front ends 06 and the rear end 07 of two circumferentially adjacent linings 04 Insert into notch 03.

[0030] The notch 03 has an opening 08 in the region of the shell surface 02 , for example a slot 08 , the width b08 of which in the circumferential direction is small, for example smaller than 5 mm, in particular smaller than 3 mm.

[0031] The first notch wall 09 cooperating with the front end 06 of the lining forms an acute angle with the shell surface 02 , in particular an ang...

Abstract

The fixing device has a channel (03) running axially. In each section of this channel perpendicular to the axial direction of the cylinder, there is a single fixing device (16) with only one lever (17). The acute angle (alpha ) between the channel wall (09) facing the front end (06) and the jacket surface (02). and the acute angle of the chamfering of the front end, are both between 30 and 60[deg].

Description

technical field [0001] The invention relates to a device for securing the front and rear ends of a lining to axially extending notches of a rotary printing press cylinder. Background technique [0002] In EP 07 13 770 B1 a clamping device for fixing a printing plate on a cylinder is disclosed, wherein a hooked end of the printing plate is hung on a hooked end of a reed, and the printing plate is The end is fastened tangentially to the shell in the section of the notch. The release of the printing plate is carried out by means of a hose which is loaded with a pressure medium. [0003] Furthermore, EP 06 06 604 B1 discloses a fastening device for printing plates with bent ends, wherein the hooked ends of the printing plate are hung on hook-shaped fastening strips prestressed by torsion bar springs , and the hook end of the fastening plate is tangent to the shell surface to be fastened within the range of the notch by using the fastening strip. In this case, the release of t...
