Patent ID: 10717203

Abstract:
A rotary die apparatus and method for three-axes registration error correction. The rotary die apparatus includes a rotary die for applying patterns to a strip of material, a sensor for sensing fiducials on the strip of material, actuators to adjust the rotary die, and a control system. The actuators adjust the rotary die along an X-axis extending along a direction of travel, along a Y-axis transverse of the direction of travel, and about a theta axis perpendicular to the X-axis and the Y-axis. The control system calculates a registration error based on a difference between an actual location or orientation of the fiducials and a desired location or orientation of the fiducials. Then the control system outputs control signals to the actuators to adjust the rotary die along the X-axis, along the Y-axis, and/or about the theta axis while the rotary die continues to rotate.
