Embodiment Construction

[0019] In the following text, reference figure 1 -7 The present invention will be described in more detail.

[0020] figure 1 showing details of an ink transfer device according to the invention as it is clamped on a rubber-covered cylinder (not shown), figure 1 The ink transfer device includes a rubber blanket 11 and a bearing member 12 corresponding to the rubber blanket 11 . rubber sheet 11 and carrier element 12 in the figure 1 Exemplary embodiments are designed as separate subassemblies.

[0021] The rubber blanket 11 is formed in a plurality of layers. The carrier element 12 can be designed as a metal carrier, as a woven fabric carrier or as a fiber-reinforced plastic carrier. according to figure 1 , in the clamped state, the carrier element 12 is positioned radially on the inside and the rubber blanket 11 is positioned radially on the outside. The carrier element 12 serves to hold the rubber blanket 11 . It should be pointed out that the carrier element 12 can a...

Abstract

An ink transfer device which can be clamped on a rubber covered cylinder in a printing press includes a rubber blanket for transferring ink from a printing forme to a printing material, the blanket having a leading end and a trailing end which are separated by a non-ink transferring gap when the device is clamped on the cylinder; a carrier element fixed to the rubber blanket; and a pair of fixing elements for clamping the blanket on the cylinder, the fixing elements being positioned on the carrier adjacent to respective ends of the blanket. In order to minimize the non-ink transferring gap, the fixing elements and the carrier element are formed as separate subassemblies which are joined together.

Description

technical field [0001] The invention relates to an ink transfer device for a printing press according to the preamble of claim 1 . Background technique [0002] In the printing units of a printing press, with the aid of a device known as an inking unit, the printing ink is transferred with the subject matter onto the printing plates positioned on the plate cylinders of the respective printing unit. With the aid of an ink transfer device, the printing ink applied on the printing plate is transferred to the printing material to be printed. The transfer means known from the prior art rely on what is known as a rubber blanket or as a rubber sleeve. [0003] The rubber blanket is formed in the form of a sleeve, and in order to position it on the rubber-covered roller, the rubber blanket is pushed axially onto the rubber-covered roller. The rubber sleeve has the advantage that non-ink-bearing gaps or channels in the area of ​​the ink transfer device can be avoided. Rubber sleev...
