Abstract
A charging device comprises a housing defining a charging chamber. Two tensioning shafts are mounted on opposite ends of the housing. The charging device comprises a control grid attached to the grid tensioning shafts, thus substantially covering the chamber opening. The control grid is comprised of a conductive material capable of being stretched along its length. As a result, the grid becomes flat when opposing rotating forces are applied to the two tensioning shafts.
