  • Patent number: 11338569
    Abstract: A screen printing device has a screen printing stencil. At least two doctor blade systems, each acting on the screen printing stencil are provided. The at least two doctor blade systems are arranged to each apply printing ink to an object to be printed in the same printing process. Each of the doctor blade systems has at least one doctor blade. Each of the doctor blades is arranged to sweep over the screen printing stencil. Each of the doctor blade systems is individually controlled by a control unit. The at least one doctor blade of each of the doctor blade systems is moved by a robot. At least respective two-dimensional motion paths of the doctor blades of each doctor blade system are each freely programmed and are established by control of the robot.

  • Patent number: 6962110
    Abstract: In an apparatus for decorating stiff objects, the objects are transported stepwise along an arcuate conveyor path. Printing stations and drying stations are arranged alternately along the conveyor path with the printing stations at a level above the conveyor path and the drying stations at a level below the conveyor path. Holders for the objects are reciprocatable upwardly and downwardly to permit vertical movements of the objects during the printing operation and/or for setting the objects in different heightwise positions in different stations. The holders for the objects are subdivided into first and second groups, wherein the holders of each group are adjustable in respect of height independently of the holders of the respective other group. The printing stations are screened from view in relation to the drying stations by screening members.

  • Patent number: 6234742
    Abstract: In a process and apparatus for decorating a flat self-supporting article which is turned for decoration thereof on both sides, the article is firstly removed from a horizontal position in an article holder by being lifted by a first pivoting means and then pivoted into a vertical intermediate position from which the article is moved by a second pivoting means producing a pivoting movement of the article into a horizontal position with its previously upward surface facing downwardly. The article is then lowered into an article holder again.
