ABSTRACT:
A screen printing machine has a reciprocable printing screen and below it a counter-pressure roller. Above the screen a squeegee unit is movable relative to the screen and has two vertically displaceable parallel squeegees. During movement of the screen in one direction, one of the squeegees forces ink through the screen and the other squeegee is retracted. During reverse movement the one squeegee is retracted and the other one pushes the ink pool over the screen back to the starting position. In the starting position, the one squeegee is lowered again and the other squeegee is retracted. The transfer of the ink pool from the other squeegee to the one squeegee takes place directly above the printing line which is defined by the screen in conjunction with the counter-pressure roller. The screen printing machine is provided with a control device for coordinating the movements of the squeegee unit with the movements of the printing screen.
