Abstract
A material web turning bar assembly utilizes one fixed lead screw and support spindle and one shiftable lead screw and support spindle to support opposite ends of a turning bar. The shiftable lead screw and spindle are supported for movement in a longitudinal direction as the end of the bar that they support is shifted in a lateral direction. The ends of the bar are supported by hinge joints and the bar itself is rotatable about its own longitudinal axis as it is shifted laterally.
