Abstract: The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.
