COMPACT HOT MELT APPLICATOR

摘要

An applicator for dispensing hot melt adhesives has a receptacle for storing solid blocks of adhesive, along with a feeding mechanism having a movable arm for advancing a single block of adhesive toward a melting chamber. A coil spring element is connected to the arm and unwraps as the arm is advanced in order to retain any remaining blocks of adhesive in the receptacle. At the end of a dispensing operation, the spring exerts just enough force on the arm in a direction away from the melting chamber to relieve pressure against the advanced block, so that the tendency for unwanted molten material to drip from the applicator nozzle is reduced.
