Abstract
According to the invention, a rotary printing machine with a printing cylinder and an ink delivery system for supplying the printing cylinder with ink with an ink chamber, which can be connected with an ink source, wherein the ink chamber has an ink discharge opening in the form of a slit, which extends mainly parallel to the printing cylinder axis and is aligned with the printing cylinder such that ink can be discharged into it.
Claims30
Rotary printing machine with a printing cylinder and an ink delivery system for supplying the printing cylinder with ink with an ink chamber, which can be connected with an ink source, characterized in that the ink chamber has an ink discharge opening in the form of a slit, which extends mainly parallel to the printing cylinder axis and is aligned with the printing cylinder such that ink can be discharged into it.
Rotary printing machine according to the previous claim, characterized in that the rotary printing machine is a rotary screen printing machine.
Rotary printing machine according to one of the previous claims, characterized in that the ink delivery system is arranged inside the printing cylinder.
Rotary printing machine according to one of the previous claims, characterized in that a doctor blade extends mainly parallel to the printing cylinder axis in the rotational direction of the printing cylinder behind the ink chamber.
Rotary printing machine according to one of the previous claims, characterized by several ink chambers each with an ink discharge opening in the form of a slit.
Rotary printing machine according to one of the previous claims, characterized in that the slits in the several ink chambers are aligned flush with each other.
Rotary printing machine according to one of the previous claims, characterized in that the slits in the several ink chambers are directly adjacent to each other and thus form a mainly continuous slit.
Rotary printing machine according to one of the previous claims, characterized in that the ink chamber is mainly flat with a contour, which extends from an ink supply opening to the slit.
Rotary printing machine according to one of the previous claims, characterized in that the shape and size of the slit in the ink chamber can be set by means of a cover plate, is controlled and/or regulated in particular by means of a quick setting means, preferably by means of a spindle.
Rotary printing machine according to one of the previous claims, characterized in that the ink delivery system is fastened, in particular releasably, on the doctor blade and/or on the doctor blade holder.
Rotary printing machine according to one of the previous claims, characterized in that the ink chamber has flow guides, in particular webs or fins, in order to enable and even ink discharge over the length of the slit.
Rotary printing machine according to one of the previous claims, characterized in that the ink chamber is fastened releasably to an element of the remaining ink delivery system.
Rotary printing machine according to the previous claim, characterized in that at least one of the several ink chambers is fastened separately or in groups releasably on one element of the remaining ink delivery system.
Rotary printing machine according to one of the two previous claims, characterized in that the at least one ink chamber is interchangeably fastened to an element of the remaining ink delivery system by quick tensioning means.
Rotary printing machine according to one of the previous claims, characterized in that at least one side wall of the ink chamber is formed by an element of the remaining ink delivery system.
Rotary printing machine according to one of the previous claims, characterized in that an ink supply opening is arranged on a side wall of the ink chamber, in particular on a side wall formed by at least one element of the remaining ink delivery system.
Rotary printing machine according to one of the previous claims, characterized by a pressure supply, from which the ink chambers are individually or, for example through a supply chamber, jointly supplied preferably mainly with the same pressure.
Rotary printing machine according to one of the previous claims, characterized in that the pressure supply has a pump, in particular a spiral pump or a pump with a cylinder/piston arrangement.
Rotary printing machine according to one of the previous claims, characterized in that the pressure supply is controlled depending on the rotational position of the printing cylinder.
Rotary printing machine according to one of the previous claims, characterized in that the pressure supply is regulated depending on the pressures in the ink chambers.
Rotary printing machine according to one of the previous claims, characterized in that an ink volume flow is controlled or regulated from the slit depending on the rotational position of the printing cylinder, preferably via at least one valve and/or the cover plate.
Rotary printing machine according to one of the previous claims, characterized in that the cylinder casing of the printing cylinder is formed at least partially from a metallic printing screen.
Rotary printing machine with a printing cylinder, characterized in that the cylinder casing of the printing cylinder is formed at least partially from a metallic printing screen.
Rotary printing machine according to one of the previous claims, characterized in that the printing screen is braided out of metallic threads.
