Abstract
Abstract This invention relates to the printing, scoring, perforating and creasing of corrugated cardboard boxes and other flat sheet material in presses, and more particularly to a means for releasably holding the printing and other types of dies formed of rubber, synthetics, wood and metal to the upper, revolving cylinder, wherein the interface between the cylinder and a die comprises minute hooks on one surface and minute loops on the other, preferably of the material commonly known as Velcro or a similar material. Such an arrangement permits the die to be more easily positioned and pressed onto the cylinder and removed.
