Abstract
Abstract A sheet winding, turning and aligning method and apparatus for printed paperboard sheets and the like wherein a stack of horizontal sheets comprising the stack are rotated in the vertical plane while being confinedly supported, beyond 90*, with the boards being projected against a curved plate to implement breaking any ink pack which may be in a load due to movement of the sheets against one another and to provide enhanced column strength to prevent a tendency of the board slipping to the bottom of the pile as retaining jaws of the turner are opened, with resultant bottom edge pressure preventing proper winding or aeration, the boards or sheets comprising the load subsequently being tilted by the device to dispose the bottom and side edges at an angle from the horizontal and the vertical planes and vibrating and aerating the bottom and side edges of said sheets when so tilted to align sheet edges.
