    摘要: A system for electrostatic powder coating irregular shaped, three-dimensional articles with 10 μm average diameter powder particles. A supply of powder particles are triboelectrically charged and transported onto one or more donor rolls without the need from fluidization of the powder particles. The charged powder particles on the one or more donor rolls are metered to provide a uniform layer thereon. A combination of AC electric fields and/or air jet detach the powder particles from the one or more donor rolls and produce a powder cloud that is directed to the grounded article to be coated. A layer of powder particles coats the outer surface of the article, and the layer is subsequently cured to form a permanent and durable film on the article.

    摘要: A non-interactive development system generates a toner cloud in a development zone by an AC biased stationary electrode positioned in contact with the back surface of a movable toned dielectric donor belt having a patterned electrode structure on the front surface thereof. The AC biased electrode produces AC fringe fields near the edges of the patterned electrode structure that cause the generation of a toner cloud for developing an electrostatic latent image. The donor belt is partially wrapped around a magnetic brush to produce a toner loading zone. Isolated patterned electrodes on the donor belt near the entrance region of the toner loading zone are biased to cause unloading of toner from the donor belt, while isolated electrodes near the exit region of the toner loading zone are biased to cause toner reloading of the donor belt.

    摘要: Non-contact corona charging of a small radius moving surface to a desired surface voltage with a single corona charging system with a first corona generator applying a first charge through a screen grid having a first bias voltage to initially charge the surface to more than half of the desired voltage, and then a second corona generator applies the remainder of the desired surface charge through a separate screen grid having a second bias voltage. The two corona generators may be spaced pin arrays angled relative to one another and substantially perpendicular to their adjacent moving surface areas. The two screen grids may be electrically planar and angled relative to one another, substantially parallel to their adjacent moving surface areas.

    摘要: A development system for an electrophotographic machine in which uncharged toner is stored in a housing having an opening. A rotatable dispensing roll is mounted in the housing opening. An overhung metering blade mounted at the housing opening meters a layer of uncharged toner onto the dispensing roll. An ion or electron charging device places a charge on the toner layer residing on the dispensing roll prior to the transportation thereof by the dispensing roll to a captive magnetic brush. The magnetic brush transports the two component developer on the magnetic brush to a development zone for either direct development of a latent image on a moving imaging surface or to coat donor rolls for AC/DC generated toner cloud development of a latent image.
