Adaptively controlling movement of rollers and guides of flexo-folder gluing machine used in box mfr.

摘要

A controller (44) is provided for calculating an updated overshoot value for a member (16,18) e.g. a roller, by subtracting the actual position from the command position and controlling a succeeding movement of the member as a function of the updated value. Compensation may also be made for ambient temperature changes, changes in air pressure if the motor is air driven, changes in voltage or current if it is electrically driven.
