Optimal angle corrugated board folder

摘要

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.
