摘要

Method and device to place the faces equipped with photosensitive screen tissue with respect to the slide and the electric arc lamp, in the drum to serigraphically decorate moving ceramic tiles, characterized in that once the slide is centered and tensioned by coincidence with a grid center drawn on an auxiliary element arranged on a cylindrical sector and fixed on the corresponding frame, the latter lifted, the drum to be printed serigraphically is inserted and fixed on the angularly displaceable disk, determining a first position by means of obturator; the drum is covered with a black paper sheath that only leaves the face to be printed first, that is, the top one; it descends and fixes the frame of the slide; the radially extensible member is actuated to close the window (upper) from the inside by means of a rubber screen and to exert from the inside on the screen tissue a pressure that makes it assume a cylindrical disposition, so that it adheres to the overlapping slide ; the lamp is lowered and lit during the due time; then, when the radially extensible element is lowered, the drum of the shutter is released, causing it to make the necessary rotation for the entrance of the obturator in the next hole of the disc; the radially extensible element is raised, the exposure to the light of the second face of the drum is carried out and so on for all the faces; the printed drum is dismantled and replaced identically with another like to print.
