Abstract
A method of controlling the flow of finish to a moving synthetic fibrous tow involves continuous non-contact monitoring of electrostatic voltage (ESV), tow speed and temperature by appropriate sensors which are interfaced with a computer that provides continuous computation of percent finish on the tow. Out of limit signals are relayed to the point of finish application to adjust the amount of finish being applied to the tow.
