Abstract
A device for rotating papers includes at least one conveyer belt for moving each paper through the device, at least one ball for rolling on top of each paper moving on the conveyer belt for holding the paper in position, retaining rails extending over the conveyer belt for rotatably retaining the ball, a fulcrum assembly positioned adjacent to the conveyer belt for stopping part of each paper while the belt pulls the paper radially around the fulcrum assembly, thereby rotating the paper. The fulcrum assembly preferably includes a fulcrum ball which rests against a paper support plate for wedging the paper when it makes contact with the fulcrum ball between the fulcrum ball and the support plate. A method for rotating papers includes the steps of placing the papers sequentially on at least one conveyer belt, holding the papers against the belt with at least one ball riding on top of the papers which is free to rotate but is retained against linear movement, blocking the path of part of each paper with a fulcrum and moving the remainder of the paper around the fulcrum with the belt so that the paper rotates around the fulcrum.
