Abstract:
An apparatus for applying a polymer to a substrate comprising:(a) directing and handling means for directing and handling a substrate material; (b) dip means associated with said directing and handling means for applying a polymer to said substrate wherein said substrate passes through the dip means; (c) a resonant frequency sensor associated with said directing and handling means located on said directing and handling means in a location proximal to said substrate and down stream of said application means; (d) data collection means in communication with said sensing means for accepting and collating data from said sensing means; (e) processing means associated with said data collections means and said directing and handling means for using said data from said resonant frequency sensor to set operational parameters for said directing and handling means; and (f) vacuum means for removing excess polymer from the substrate after application of the polymer in the dip means.
