Abstract:
An apparatus for depositing a coating material, such as an organic monomer, in vapor form onto a substrate including a heated evaporation chamber having an inlet for introduction of the coating material into the chamber and a nozzle having an adjustable opening for adjusting cross direction coating uniformity. The nozzle may include a plurality of adjustment bolts spaced along the width of the nozzle for adjusting the opening of the nozzle. The adjustment bolts may be alternating push and pull adjustment bolts. Alternatively, the adjustable bolts are bolts having compound threads such that each bolt is capable of both pulling and pushing the adjustable opening of the nozzle. The substrate is preferably a moving web that defines the outer surface of a cooled drum. The apparatus further includes a radiation source positioned adjacent to the substrate for curing an organic monomer coating on said substrate. The radiation source may be an electron beam gun or an ultraviolet lamp.
