A corrugated board folder is disclosed for folding the flap of a corrugated board onto the base of the corrugated board along a fold line having an inside fold line and an outside fold line. The corrugated board folder includes a conveyor mounted on a frame for supporting the corrugated board during folding and a series of rollers that engage the flap of the corrugated board. Each roller in the series of rollers is supported adjacent the conveyer by a roller bracket. The roller has an axis which pivots about a bracket pivot point of the roller bracket. The bracket pivot point for each bracket is aligned with the inside fold line of the corrugated board and each roller is angularly positioned to squarely engage the flap of the corrugated board.

[ I claim:] [1.] A corrugated board folder comprising:a. a frame;b. a conveyor mounted on the frame for conveying a corrugated board including a base and a flap to be folded from an upright position to a doubled over position on the base along a fold line defined by an inside fold line and an outside fold line, the conveyor including a flap conveyor adjacent the flap and a base conveyor adjacent the base;c. a series of roller brackets mounted along the frame, each roller bracket having an arcuate keyway with a shape of an arc having a center, the center being a bracket pivot point;d. a series of slides corresponding to respective ones of the roller brackets, each slide slideably engaged within the arcuate keyway of a respective one of the roller brackets for selective movement along the respective one of the roller brackets;e. a series of rollers corresponding to respective ones of the roller brackets, each roller having an axis and mounted to a respective one of the slides; andf. a series of locks for fixing the slides in a position on the respective roller brackets,wherein the rollers are mounted to the slides and the brackets are mounted to the frame such that the bracket pivot point of each keyway coincides with the inside fold line of the corrugated board, the axis of each roller at any point along the respective arcuate keyways is perpendicular to a radius through the inside fold line, and the rollers are positioned square against the flap conveyor, whereby each roller in the series can be arranged and locked in position about the inside fold line of the corrugated board to fold the flap of the corrugated board from the upright position to the doubled over position, without buckling the corrugated board, while the corrugated board is conveyed by the conveyor past the rollers.
