Abstract

Proposed is an apparatus for electrically grounding rotating shaft mandrels contained in a rotary atomization coater. Figure 1 schematically illustrates an annular grounding plate 10 composed of approximately 0.125-inch thick copper. Plate 10 is located near the perimeter of a mandrel transporter (not shown) by four mounting holes 14. A tab 16 and screw 18 provide a means for connecting plate 10 to an externally grounded source. A plurality of drilled and tapped holes 12 correspond to the end of each mandrel shaft. As shown in Figure 2, copper bolts 20 (with the lead end's ground to a point) complete the grounding circuit by passing through holes 12 to contact the mandrel shafts.
