Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) Published: — with international search report (Art. 21(3)) (54) Title: DIE BLOCK, STEEL-RULE DIE ASSEMBLY COMPRISING THE SAME, AND METHOD THEREOF (57) : 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 magnet- ic element(s) in proximity to the kerf(s) allows maintaining the corre- sponding rule(s) in position within its kerf even if the kerf is cut \"loose- ly\". The corresponding rule may be quickly and easily inserted and ac- curately maintained even if the die block expand or retract under atmos- pheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifmg and longer run— time.
