<p>A process for plating the outer peripheral surface of a hollow roller adapted for plating copper or chromium on the outer peripheral surface of a hollow roller and especially a gravure printing block roller and an apparatus for automatically attaching or detaching a cassette type hollow roller. The conventional mechanism for automatically attaching or detaching a gravure printing block roller by chucking both ends of the horizontal roller and rotating the roller should be provided at each of the plating machines. This apparatus, on the other hand, eliminates all the plating machines and also the automatic attaching and detaching operations of the hollow rollers at the respective plating machines. Only the automatic hollow roller attaching and detaching mechanism portion is separated from the machine body and formed into the shape of a cassette. Thus, the hollow roller is detached merely at the initial and the last of the plating steps, but retained to be gripped with the hollow roller by the cassette midway of the step and sequentially moved to the series of the machines. This apparatus chucks the hollow roller R with energizing supports (22A, 22B) at the ends of a pair of spindles (21A, 21B) axially movable at least at one side of a suspending frame (13) and prevents the supports from being plated with plating liquid by liquid preventive caps (23A, 23B) at the outside of the spindles. Thus, this apparatus can move the frame (13) by a hoist.</p> |
