Abstract
A system is described for venting the gas line of an air sensing device used to determine package build on a winding device for winding strand to prevent inaccurate readings of the air sensor caused by moisture. The venting system is operated through a solenoid switch to send air through the main air sensing channel in the reverse direction when the winder is stopped for package replacement.
