Abstract
A method and apparatus for transporting workpieces during surface altering treatment in which each workpiece is mounted on a holder which moves along a guide slot forming a non-circular, closed path. A double sprocket chain extending along one side of the slot engages a gear of each workholder for moving the holders along the slot as the double chain is driven. A second chain on the other side of the slot also engages the gear to rotate the holders as they move along the slot. Links connect the holders and cover the portions of the slot not covered by the upper surfaces of the holders on which the workpieces rest. The workpieces are thus uniformly treated, for example, coated.
