ABSTRACT:
A paper folding apparatus has a buckle chute disposed between an inlet feed roller pair and an exit feed roller pair which are arranged to provide a substantially linear feed path for a paper article being folded and fed through the apparatus. The inlet feed roller pair is mounted on respective support members which permit adjustment of the position of one of the feed rollers of the inlet feed roller pair to change the path of the leading edge of the paper article as it moves through the inlet feed roller pair toward the buckle chute. A common drive gear is meshed with drive gears on rollers on each of the feed roller pairs and the feed roller drive gears are meshed with cooperating drive gears connected to the other rollers of each roller pair, respectively. The linear feed path through the folding station minimizes wrinkling of the article being folded and the production speed of the apparatus is significantly greater than conventional buckle chute folders which substantially change the direction of feeding of the folded article.
