<p>Magnetic bar (1) for a roller squeegee in a rotary screen printing device which, in order to be able to vary the magnetic force for attracting the squeegee, comprises two parts (2, 3) which are displaceable with respect to each other. The top part (2) is a part of non-magnetically conducting material with elements (13) of magnetically conducting material. The bottom part (3) is a part comprising permanent magnets (11). By sliding the bottom part (3) relative to the top part (2) the magnetic force for attracting the roller squeegee can be varied.</p> |
