ABSTRACT:
An improved paper guide device is disposed close to folding rollers in a folding machine of a rotary press as spaced from an outer circumference of a folding drum. During normal operation, the paper guide device is preset to allow for minute movement of the folding rollers during the folding operation. But when the folding rollers clog with paper and move apart beyond a predetermined distance, the paper guide device moves as interlocked with the folding rollers. Therefore, paper guides of the paper guide device never contact the folding rollers. Preferably, the position of the paper guides relative to the folding rollers can be changed such that the widths of the respective gaps between the paper guides and the folding rollers can be adjusted.
