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.
Claims22
A process comprising:
- providing a moving substrate;
- applying at least one coating layer onto the moving substrate with a slot die coater equipped with at least one position sensor mounted on at least one, and for example from one to about five end of the slot die coater;
- sensing the position of the slot die coater relative to the moving substrate with at least one position sensor;
- and
- when the position of the slot die coater relative to the moving substrate deviates from a set of predetermined coordinates,
- iteratively adjusting the position of the die coater relative to the surface of the substrate to return to the set of predetermined coordinates.
An apparatus comprising:
- 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.
A xerographic apparatus comprising a charging component, an imaging member component, a fusing component, a transfer component, and a development component.
