ABSTRACT:
An adhesive discharge device for use with adhesive which sets by the evaporation of a solvent. The device incorporates a valve-controlled discharge nozzle for intermittent discharge of adhesive on a cycle basis. Drying of adhesive around the nozzle opening when the valve is closed and the discharge of adhesive is interrupted is prevented by a movable closure cap containing a solvent vaporizer. The closure cap is movable into a position enclosing and sealing the nozzle opening, and the vaporization of solvent inside the closure cap around the nozzle opening prevents the drying and encrustation of adhesive.
