Abstract: A kerf lock is provided for the retention of die cutting dies in die slots of a retaining board. A retaining system is also provided and includes a plurality of lock slots oriented substantially perpendicularly to a direction of insertion of a die cutting die. The lock slots have open faces to permit communication with the die slots. When the kerf lock is located within a lock slot it 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 laterally. Once the die is completely 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 die cutting die can thus be securely held within the die slot.

Abstract: The present apparatus applies force along a line or to a surface through one or more linear or rather longitudinal, elastically expandable or deformable members. The expansion of the elongated member, such as an elastic, reinforced hose or membrane, is transmitted to the tool proper, for example, a strip steel knife or a clamping device, along the entire length of the tool, whereby a linear force application is achieved. Several of such members may be arranged in parallel to obtain substantially a surface area force application. The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.
