Abstract

Cylinder engraving device for stamping, essentially for the printing of fabrics and paper, characterized by comprising, in a bed, a set of two parallel cylinders, arranged according to the length of the bed, synchronously rotating on their respective axes, one of whose cylinders it constitutes the carrier element of the printed pattern sheet, while the other comprises a continuous metal sheet without joining edges or perforations, one and the other envelope of their respective carrier cylinders; and for understanding a sliding body by mechanical displacement on a spindle and on parallel guides that are parallel and spaced apart in a plane. Superior to that of the knees, whose sliding body constitutes the support of a photoelectric cell and of a recording tip protruding by its base in its corresponding assembly elements parallel to each other and perpendicularly incident on the highest generatrix respectively of the carrier cylinder of the standard sheet and the carrier cylinder of the metal foil, also constituting the assembly for converting the image pulses in the photoelectric cell into mechanical pulses in the recording needle; the device also comprising a step calculation box controlling the displacement of the sliding body and the rotation of cylinders, determinant of the printing pattern and, a high-frequency spark control element, determining the formation of perforations no flash on the metal sheet.
