Abstract
An apparatus for coating photoreceptor devices comprises a manifold forming a conduit, the conduit having a length with an input at one end. Multiple diptanks for applying photoreceptor coating solution to devices dipped therein are mounted on an upper portion of the manifold and distributed along the length. The conduit is arranged so that photoreceptor coating solution supplied to the input flows to the diptanks, thus forming a photoreceptor coating solution flow in each diptank. The conduit becomes increasingly narrower as the photoreceptor coating solution flows along the length successively from one diptank to the next diptank. As a result, the photoreceptor coating solution flow speed in each diptank is substantially the same.

An apparatus for coating photoreceptor devices,
- the apparatus comprising a manifold forming a conduit, the conduit having a length with an input at one end thereof,
- the apparatus further comprising a plurality of diptanks mounted on an upper portion of the manifold and distributed along the length, the plurality of diptanks arranged for applying coating solution to photoreceptor devices that are dipped therein,
- the conduit arranged so that the coating solution supplied to the input flows away from the input in a flow direction towards the plurality of diptanks thus forming therein a corresponding plurality of diptank coating solution flows, each diptank coating solution flow comprising a corresponding diptank coating solution flow speed, the conduit defining a conduit inner diameter that becomes increasingly narrower along the length in the flow direction such that the plurality of diptank coating solution flow speeds are substantially uniform.

- the conduit arranged so that the coating solution supplied to the input flows away from the input in a flow direction towards the plurality of diptanks thus forming a diptank coating solution flow with a corresponding diptank coating solution flow speed in each of the plurality of diptanks,
- the conduit being wedge-shaped thus defining a wedge-shaped conduit inner diameter that becomes increasingly narrower along the length in the flow direction, thereby causing each of the plurality of diptank coating solution flow speeds to be substantially equal with respect to each other.
