ABSTRACT:
A nozzle assembly for electrostatically dispensing a flowable material at a controllable rate and in a reliable and uniform manner includes a housing with a dispensing edge and front and rear members joined together to provide a continuous dispensing slot along the dispensing edge. The nozzle is a unitary device having a plurality of substantially hydraulically independent chambers therewithin in fluid communication with the substantially continuous and uninterrupted dispensing slot, whereby flowable material can be selectively supplied to the individual chambers to control the width of material application without structurally modifying the nozzle itself. Field gates are provided at each end of the nozzle to further control the deposition of the charged material, and the nozzles can be oriented to dispense flowable material in substantially any orientation, including vertically upwardly.
