Compact hot melt applicator. |
摘要 |
<p>An applicator (10) for dispensing hot melt adhesives has a receptacle (24) for storing solid blocks (28) of adhesive, along with a feeding mechanism (30) having a movable arm (32) for advancing a single block (28) of adhesive toward a melting chamber (14). A coil spring element (64) is connected to the arm (32) and unwraps as the arm (32) is advanced in order to retain any remaining blocks (28) of adhesive in the receptacle (24). At the end of a dispensing operation, the spring (64) exerts just enough force on the arm (32) in a direction away from the melting chamber (14) to relieve pressure against the advanced block, so that the tendency for unwanted molten material to drip from the applicator nozzle (20) is reduced. <IMAGE></p> |
