Abstract

In fabricating photoreceptors, a rotary atomizer spray chamber may be employed to deposit layered material onto a plurality of substrates. FIG. 1 illustrates a schematic, plan view of a typical spray chamber planetary arrangement in which a plurality of substrates 2 is arrayed on shafts 4 around the central axis 6 of the chamber. However, efficient use of the spray chamber requires that as much of the usable volume in the spray chamber be utilized as possible. It is desirable to be able to load and coat very large numbers of substrates within a given coater run.

ROTARY ATOMIZER PLANETARY ARRANGEMENT (Cont'd)

In fabricating photoreceptors, a rotary atomizer spray chamber may be employed to deposit layered material onto a plurality of substrates. FIG. 1 illustrates a schematic, plan view of a typical spray chamber planetary arrangement in which a plurality of substrates 2 is arrayed on shafts 4 around the central axis 6 of the chamber. However, efficient use of the spray chamber requires that as much of the usable volume in the spray chamber be utilized as possible. It is desirable to be able to load and coat very large numbers of substrates within a given coater run.

FIG. 2 illustrates a schematic, plan view of a new spray chamber planetary arrangement which substantially increases the usable volume within the spray chamber and which enables large numbers of substrates to be handled in each coater load. In FIG. 2, there are six main shafts 8 arrayed about the central axis 6 of the spray chamber and six secondary shafts 10 are arrayed around each of the main shafts 8. A spray gun (not shown) traverses along the central axis 6. The rotation of the main shafts 8 permit two secondary shafts 10 of substrates 2 to...
