Abstract
1,052,362. Electrostatic printing apparatus. ELECTROSTATIC PRINTING CORPORATION OF AMERICA. April 21, 1965 [Aug. 28, 1964], No. 16900/65. Heading B6C. In an electrostatic stencilling apparatus in which an electrostatic field forces powdered ink particles through an endless band imaged screen 10 on to a web 18 the particles are pneumatically carried to the under region of the screen prior to being forced therethrough by an electric field emanating from a wire grid formation of electrodes 54. The air current and any residue powder are removed from below the screen by an air vacuum source operating through a chamber 58 and filter 64. The powder particles are stored in the fluidized state in a reservoir 20 and, through the connection of an air pressure source 32 to a nozzle arrangement 52 having in its base an inspirator device, are withdrawn therefrom and fed to the region beneath the screen through a powder metering device 26 and the nozzle arrangement. In a modified construction, Fig. 4 (not shown), which may be used for stencilling bottles the powder laden air is allowed to " drift " across the underside of the screen through a " drift chamber." In this embodiment each stencilling operation is followed by a scavenging operation in which any powder trapped by the interstices of the screen is removed by passing a high volume of air through the " drift " chamber.
