Embodiment Construction

[0026] Figure 1-7 is a schematic view in which, for greater clarity, the sectioned components are shown in unshaded manner. in the attached Figure 1-7 In , the parts corresponding to each other are marked with the same reference numerals.

[0027] figure 1 A printing press 1 is shown in section, which is used for printing sheets B by offset lithography. The special equipment 2 of the printing press 1 is shown, which is arranged in series with the offset printing tools of the printing press 1 which are not shown in the figure. The special device 2 has a vacuum drum 3 which, during the transport of the sheets B, receives the sheets B from a feed roller 4 and transfers them to a feed roller 5 . This vacuum drum 3 can also be referred to as a vacuum drum system. The vacuum drum 3 has radial drum channels 6 in which clamping grips 7 are respectively arranged for holding a sheet B at its leading edge. see Figure 4 , if the special equipment 2 is an inert gas drying equipme...

Abstract

A vacuum drum system for a printing material sheet processing machine includes suction grooves for pneumatically holding a sheet of printing material and closing slides disposed in the suction grooves. A drying unit having the vacuum drum system is also provided.

Description

technical field [0001] The invention relates to a vacuum drum system of a machine for processing sheets of printing material and a drying device. Background technique [0002] DE 10346782A1 and DE 102010000996A1 describe a vacuum drum with suction grooves for the fixed holding of sheets of printing material. The described vacuum drum is used as a storage cylinder in a turning arrangement of a printing press. The negative pressure in the suction tank can be shut off by means of a valve. These prior art vacuum drum systems are not well suited for use in specialized equipment for printing presses. Contents of the invention [0003] The object of the present invention is to propose a vacuum drum system well suited for use in special plants and a special machine equipped with this vacuum drum system. [0004] The above object is achieved by a vacuum drum system having the features of claim 1 and a drying plant having the features of claim 10 . [0005] The vacuum drum syste...
