Abstract:
A device for placing a charge on an object passing by and proximate to the device in a first direction along a transport axis, the device comprising:a body having a surface; a first plurality of rows of ionizing pins disposed in the body for emitting ions from locations proximate to the surface of the body, each of the first plurality of rows of ionizing pins having a first row axis that is aligned generally parallel to the transport axis, the first plurality of rows of ionizing pins are positioned in a generally spaced apart side by side fashion; a second plurality of rows of ionizing pins disposed in the body for emitting ions from locations proximate to the surface of the body, each of the second plurality of rows of ionizing pins having a second row axis that is aligned generally parallel to the transport axis, the second plurality of rows of ionizing pins are positioned in a generally spaced apart side by side fashion, wherein the first plurality of rows of ionizing pins and the second plurality of rows of ionizing pins being disposed so that at least a portion of the object moving in the first direction by and proximate to the surface of the body passes by and proximate to at least one of the first plurality of rows of ionizing pins before passing by and proximate to at least one of the second plurality of rows of ionizing pins, the second plurality of rows of ionizing pins being laterally offset with respect to the first plurality of rows of ionizing pins so that the second plurality of rows of ionizing pins is generally aligned with positions between pairs of the first plurality of rows of ionizing pins; and whereby the object is charged by passing the object by and proximate to the surface of the body in the first direction to receive ions generated from both the first plurality of rows of ionizing pins and the second plurality of rows of ionizing pins.
