摘要：An applicator assembly for applying hot melt adhesive to a substrate such asthe end flaps of a sift-proof carton includes slot nozzles employing elongated, wear-resistant doctor blades formed with a fluid discharge slot. The doctor blades, preferablyin the form of hardened steel plates, are releasably clamped to the body of theapplicator in communication with the outlet of an internal passageway in the applicatorbody which receives adhesive from a flow control device such as an adhesive gun. Theplates forming the doctor blades are separated by a shim to define the fluid dischargeslot into which the adhesive flows from the internal passageway. The lowermost ends ofthe doctor blades are formed in various configurations to spread the adhesive in thedesired pattern or thickness on the substrate depending upon the type of adhesiveemployed or the requirements of a given application.
