  • Folder apparatus
    Patent number: 4053150
    Abstract: The folding blade or knife of a quarter folder apparatus for paper such as newsprint includes a pair of air jets, one on each side of the top portion of the blade, directed toward the paper being folded. The air jets are supplied from a compressed air source through a flexible tubing. The air jets maintain the ends of the pages being folded in a flattened and aligned configuration throughout the folding operation, thereby preventing wrinkled and dog-eared pages in the folded paper.
