ABSTRACT:
The machine is used, for example, in the production of printed circuits.
The frame (5) supporting the screen cloth (3) is moved in a plane which always remains approximately parallel to the plane of the circuit (2) to be printed, and the machine is equipped, in each corner of the frame, with a tracer (9) which detects an exact height of the cloth (3) and which commands independently in each corner the stopping of the means (7, 8, 10, 17) for the lowering of the frame, so as to establish a reference height, on the basis of which fine adjustments can subsequently be programmed.
