  • Treating apparatus equipped with a swing mechanism
    Patent number: 4890633
    Abstract: An apparatus for treating a workpiece by a pre-treatment process before painting or for a washing process in an electrodeposition treatment. The workpiece is transferred through a series of treating zones. The apparatus has a plurality of hanger disposed on the right and left sides relative to the advanceing direction of the workpiece, a pair of hanger travelling rails, a hanger carrying mechanism and a plurality of hanger lifting assemblies disposed on the right and left sides of the advancing direction. Each rail consists of fixed rail portions and movable rail portions. Right and left lifting assemblies are controlled in cooperation, simultaneously or alternately, to move the hangers up and down allowing the workpiece to tilt or oscillate within the treating zone.
