Abstract: A screen-printing squeegee, as well as an apparatus for screen printing, includes an elastic application element and a holding apparatus for the application element. The holding apparatus is divided, as viewed over the width of the application element, into a plurality of holding sections which can move with respect to one another, in which a leaf spring element is provided. The leaf spring element interconnects the holding sections which can move with respect to one another.

Abstract: A printing installation for printing on curved surfaces, includes a squeegee, a printing screen maintained in a screen frame, and a drive for moving the squeegee. The screen frame, on at least one side thereof, is flexible in at least some sections thereof. The screen printing device is used, for example, for printing on curved vehicle window panes.

Abstract: Squeegee assembly for a screen printing machine with a printing table, wherein the squeegee assembly has at least one squeegee, one squeegee holder and at least one support displaceable across the printing table, wherein the squeegee is held on the support by means of the squeegee holder and can be pressed against the printing table by pressure cylinders, characterized in that the support has a U-shaped profile, and at least the cylinder sections of the pressure cylinders are accommodated within the U-shaped profile.

Abstract: Disclosed is a top part of a screen printing machine, wherein the bearing elements (4,4a) for the screen printing stencil (2) are respectively and directly guided and held on lateral longitudinal guide elements (10,11) by means of carriages (9), enabling said bearing elements (4, 4a) to be adjusted in relation to each other and to be fixed. Said configuration makes it possible for the screen printing stencil (2) to be held in a stable and exact manner, irrespective of the size thereof. According to the invention, one of the bearing elements (4a) can also be raised in order to lift the screen printing stencil (2) when pressed against the other bearing element (4). The bearing elements (4, 4a) are thus respectively held on the carriers thereof (7,8) by means of pivoting hinges (5, 6).
