Laminated charge plate for an ink jet printing device and method of manufacturing same

Abstract From the Canadian patent

Abstract of the Disclosure, A charge plate is provided having a plurality of alternately sandwiched conductive and nonconductive elements with an end portion of each conductive element forming a charge surface which is positioned to correspond to an orifice position in an ink jet printing head with adjacent conductive elements being separated by the nonconductive elements. In one embodiment the nonconductive elements extend beyond the end portions of the conductive elements between positions of adjacent orifices and can be provided with additional spacer members opposite the charging surface on the opposite side of each orifice to form a series of tunnels associated with the orifices.
