Nozzle for coupling electromagnetic energy and heatable composition

A nozzle for application of an extrudable material to a substrate optically couples an electromagnetic beam to the extrudable material. The nozzle forms a flow channel with a window at one end. The extrudable material is admitted to the flow channel such that it flows across the bottom surface of th...

Beschreibung
Zusammenfassung:	A nozzle for application of an extrudable material to a substrate optically couples an electromagnetic beam to the extrudable material. The nozzle forms a flow channel with a window at one end. The extrudable material is admitted to the flow channel such that it flows across the bottom surface of the window and through the flow channel. The nozzle is removably held in a head to permit replacement of the nozzle when worn or for installation of a nozzle having different characteristics for a different application.
