The procedure for positioning, particularly of a printed circuit on a screen printing machine, comprises a first automatic position phase of the support of the printed circuit, which has one or more register marks, on the printing table of the screen printing machine and a second automatic positioning phase of the support or printed circuit relative to the printing table of the screen printing machine and of the printing plate holder frame of the same, guided on the basis of the deviation of the register marks of the printed circuit support from the corresponding register marks of the printing plate. The apparatus for carrying out the above procedure comprises a printing table for supporting a printed circuit, a printing plate holder frame and elements for the automatic positioning of the support of the printed circuit; there are also means for orienting the support or printed circuit above the printing table to bring said support or printed circuit into perfect collimation with the printing plate. <IMAGE> |
