Embodiment Construction

[0020] exist Figures 1 to 4 In , elements and components corresponding to each other are denoted by the same reference numerals.

[0021] exist figure 1 The printing press 1 is shown in detail in FIG. The printing press 1 is used for offset lithographic or offset lithographic printing on sheets. The partial illustration shows a washing device 2 of the printing press 1 . The washing device 2 can have a wash cloth that can be unwound and rolled up or a rotating brush roll for washing cylinders, such as impression cylinders or blanket cylinders. The cylinder circumferential surface to be cleaned and / or the cleaning elements (washing cloth, brush roller) pressed against it are first moistened with cleaning medium and then with rinsing water. The circumferential surface of the cylinder can be formed by a non-slip sleeve or a blanket. Furthermore, the printing press 1 includes at least one dampening device, which is not shown for reasons of clarity and simplicity. The dampeni...

Abstract

The method involves filling a tank (4) with biocide-free water supplied from a domestic water system (3), based on the water pressure of domestic water system, and pumping the water from tank for washing the printing machine components, without depending on the pressure of water. The tank is integrated to a water line (5) which leads to a fountain water supply unit (7).

Description

technical field [0001] The invention relates to a method for supplying water to a washing device of a printing press. Background technique [0002] The printing press is equipped with a washing device for cleaning cylinders or rollers. The washing device applies washing medium and rinsing water to the drum or roller during cleaning. A separate storage container can be provided for the washing medium and the rinsing water. Faults that often occur in practice are that the rinsing water is contaminated by the washing medium during the filling of the containers. The filling is mostly carried out by auxiliary workers who sometimes do not work with sufficient care. For example, the auxiliary worker fails to notice that a different pouring bucket is used for filling the container for the washing medium than for the rinse water. The wash media that enters the rinse water is a catalyst for microbial growth. The microorganisms cause slime formation in the water container and in t...
