ABSTRACT:
An apparatus is provided for improved retention of steel rule dies inserted into die slots of a retaining board. A plurality of lock slots are oriented substantially perpendicularly to the direction of insertion and have open faces to permit communication with the die slots. A kerf lock is located within each lock slot and extends into the die slot until a die is inserted into the die slot. Upon initial insertion of a die into the die slot, the kerf lock compresses. Once the die is competely inserted, the kerf lock exerts a normal force against the die in the direction of the die slot wall opposite the open face. An inserted steel rule die is securely held within the die slot.
