Abstract
A low noise air nozzle system for fanning and separating stacked sheet to facilitate single sheet pick-up. The system employs nozzles which are provided with a diverging air ejection channel which terminates at the nozzle face in an orifice slit 0.025" wide.
Claims1
The low noise air nozzle for fanning stacked sheet comprising:
- (a) a nozzle body with an entrance portion in the rear and an exit portion in the face;
- and wherein said entrance portion is bored to provide a cylindrical supply channel, said supply channel terminating within said nozzle in a conical configuration;
- and wherein said exit portion is milled to form a thin planar slot, said planar slot joining the base of said conical configuration with said nozzle face to form an ejection channel with a longitudinal flow axis, said ejection channel terminating in the face of said nozzle as a thin vertical planar slit about 0.025" in width;
- and wherein the upper and lower walls of said ejection channel diverge at an angle of 5.degree. to 7.degree. in progressing from said junction to said face;
- and
- (b) means joining said supply channel to provide air to said nozzle.
