<p>A rotary die-cutter having a planetary configuration for die-cutting paper products such as corrugated and solid-fiber paper board includes a frame in which is mounted a rotatable turret assembly. Rotatably attached to the turret assembly is a first die-cutting cylinder, a second die-cutting cylinder, and an anvil. Various tools or forms are detachably mounted to the exterior of the first and second die-cutting cylinders to cut, score, or crease paper box packaging materials. Each die-cutting cylinder is either in an operational position or a set-up position depending on the orientation of the turret assembly. In order to change the tools or forms of a die-cutting cylinder, the turret assembly is rotated such that the operational die-cutting cylinder moves to the set-up position, while the die-cutting cylinder in the set-up position simultaneously moves to the operational position. The die-cutter permits an operator to remove the die from the previous order and mount the die for the next order on the die-cutting cylinder that is in the set-up position, while the operational die-cutting cylinder is in the process of die-cutting. As a result, order changes on the die-cutter can be achieved with very little downtime as the turret assembly pivotally rotates the die-cutting cylinders into position.</p> |
