(57) Plate-holder skirt for removable-skirt lithographic printing presses, suitable for
printing in many colours on cylindrical bodies and the like, constituted by a cylindrical
body (1) having, along one of its generatrices, at least three radially-protruding
pins (8) on which an equal number of holes present along a side of a plate are slid,
said holes being obtained during the photoengraving process, by a punching preliminarily
carried out on the same plate and on all of the plates which compose the image to
be printed, by at least one bar for the fastening of the edge of said plate to the
skirt (14), and by at least another bar (17, 17a), fastened to the opposite side of
the plate, and fixable to the ends of two arch-shaped elements, hinged onto the front
faces of the cylindrical body, so to be able to be turned against the same cylindrical
body, thus carrying out the tensioning of the plate, in counteraction to spring elements,
or the like, able to secure the regular tensioning of the same plate during the printing
process.
