A rotatable shuttle transfer unit for transferring a workpiece from a first work station to a second work station along a predetermined path of travel wherein a pair of spaced carriages carry the worpiece along the predetermined path of travel and rotate the worpiece from a first angular orientation to a second angular orientation with respect to an axis of rotation. Preferably, the carriages rotate the workpiece while carrying the workpiece along the predetermined path of travel. The carriages are transported along a guiderail which extends between the first and second work stations. A continuous drive belt reciprocally drives the carrieges along the guiderail wherein the continuous drive belt extends from one end of the guiderail to the opposite end of the guiderail. A vertical lift portion reciprocally moves the woripiece in a direction substantially normal to the predetermined path of travel. In addition, the carriages provide releasable power clamps for engaging and securing the workpiece.
