Abstract
A single piece control grid electrode for a corona charging device for charging a curvilinear shaped dielectric support member with improved charging uniformity and consistency and with lower assembly and service cost. The single piece control grid is formed by a plurality of integral planar segments angularly oriented with respect to each other so that each segment may be equally spaced from the curvilinear shaped dielectric support member.
Claims5
A control grid electrode for attachment to a corona charging device for charging a curvilinear shaped dielectric support member, said control grid electrode comprising:
- a plurality of planar segments, attached to each other and oriented with respect to each other so that said planar segments may be substantially equally spaced, at a predetermined distance, from said curvilinear shaped dielectric support member, said segments each respectively including a pair of spaced end sections and a center section terminating at each end to said end sections.
A corona charging device for charging a curvilinear shaped dielectric support member, said corona charging device comprising:
- a housing including substantially parallel longitudinal side walls, and traverse end sections, said longitudinal side walls terminating at said transverse end sections;
- a plurality of substantially parallel corona wires extending in a longitudinal direction from one said traverse end section to the other said traverse end section;
- and
- a control grid electrode mounted on said housing, parallel to and spaced from said corona wires, said control grid having a plurality of planar segments, attached to each other and oriented with respect to each other so that said planer segments may be substantially equally spaced, at a predetermined distance, from said curvilinear shaped dielectric support member, said planar segments each respectively including a pair of spaced end sections and a center section terminating at each end to said end sections.
