ABSTRACT:
An apparatus including: a movement device that moves an object to be coated; a slot die coater equipped with a position sensor mounted on at least one end of the slot die coater and which slot die coater controllably dispenses coating material onto the moving object; and at least one servor motor-controller system in electrical contact with the position sensor, wherein the position sensor senses the position of the slot die coater relative to the object and wherein the at least one servor motor-controller system adjusts the position of the slot die coater relative to the object if the position of the slot die coater relative to the moving substrate deviates from a set of predetermined coordinates.
