Abstract
A material dispenser having a dispensing tube assembly having an outlet end with an orifice from which material is dispensed onto a surface, and an inlet end having an opening adapted to receive material from a supply during a dispensing operation; and means for imparting orbital motion to said outlet end relative to an axis; the tube assembly having a first section having the inlet end at a first end thereof, a second section having the outlet end at a first end thereof, and a third section that flexibly joins the first and second sections. In one embodiment the flexible third section includes a plurality of rings or hoops to increase hoop strength. A shield liner and air wash features are used to reduce the amount of dispensed material that collects on and in the gun. The dispensing tube is arranged to prevent pivoting movement at a primary pressure seal.
