Title:
APPARATUS AND METHOD FOR CALCULATING REGISTRATION ERROR OF A ROTARY DIE
Document Type and Number:
WIPO Patent Application WO/2012/039934
Kind Code:
A3
Abstract:
A rotary die apparatus and method for determining a registration error of a pattern applied to a strip of material by a rotary die. The rotary die apparatus may comprise the rotary die and a control system which senses signals from a sensor and a rotary encoder to determine an actual position of the rotary die when a fiducial on the strip of material is sensed. The control system may calculate the registration error by comparing the actual position with a registration target corresponding to a pattern length. The pattern length may correspond to the number of encoder pulses output per revolution of the rotary die divided by the number of patterns spaced apart around the circumference of the rotary die. An encoder count used to determine the actual position of the rotary die may reset each time it reaches the pattern length.
