Abstract: The spacing between a paint applicator and an auto body surface can be measured by a tool that is screwable onto the applicator in place of the paint spray head. The measuring tool includes a mounting fixture and a deflectable wand having an effective length that corresponds to an optimum spacing between the auto body surface and paint applicator. The paint applicator can be calibrated (adjusted) while the measuring tool is affixed to the applicator. All paint applicators in the system can be calibrated by a single pass of an auto body through the paint booth in which the paint applicators are located.

Abstract: Paint accumulations can be removed from paint atomizer applicator heads by passing pressurized solvent through the heads for prolonged time periods, e.g. one hour or more. Several paint applicator heads can be connected to an overhead piping system located in a treatment tank, so that solvent and entrained particulates can collect in the tank. An external filter and motor-operated pump can be connected to the tank and piping system for recirculating the solvent through the paint applicator heads on a continuing basis.

Abstract: A tool for installing and removing a turbine body and connected bell cup assembly into and out of a turbine body housing of a rotary powder coating electrostatic spray applicator is provided. The tool includes a first plate with an elongated aperture with a blind end. The first plate has a first surface for axial engagement with a radial surface of the turbine body. A second plate is connected with the first plate. The second plate has an elongated aperture with a blind end generally aligned with the elongated aperture of the first plate. The second plate has a first surface for axial engagement with the turbine body. The second plate also has a second surface generally opposite the first surface isolating the bell cup assembly from the turbine body. A handle is connected with the second plate.

Abstract: A pressure gauge assembly is disposed between a pump which pumps a powder from a fluidized bed and a spray applicator which sprays the powder onto a workpiece such as a vehicle body moving along a painting line. The pressure gauge assembly provides and early warning of clogging in the pump and/or applicator.

Abstract: An apparatus for reducing undesirable powder accumulation on an electrostatic powder coating device is provided. The apparatus includes a pneumatic source for generating a pneumatic supply. The pneumatic supply is received and distributed by a pneumatic distribution device which provides the pneumatic supply to a pneumatic diffuser. The pneumatic diffuser directs a pneumatic stream at the electrostatic coating device such that undesirable powder accumulation on the electrostatic powder coating device is reduced.
