Abstract
An automatic paper-threading device for use in an angle bar section of a rotary press which includes a paper web supply unit, a press unit, an angle bar section, and a folding unit and which has a paper-threading path for paper web formed between the paper web supply unit and the folding unit. The angle bar section is disposed in the paper-threading path and includes a first bar and a second bar disposed in parallel and separated by an appropriate distance. The automatic paper-threading device includes a paper leader guide and a tensioner. The paper leader guide includes a drive unit for moving along the paper-threading path a paper leader affixed to a leading end portion of paper web. The tensioner is provided in the angle bar section and includes a paper guide which is disposed between the first bar and the second bar to extend the widthwise direction of the paper web. The paper guide is moved between a standby position where the paper guide does not interfere with the paper-threading path and a projection position where the paper guide projects across the paper-threading path to thereby urge the paper web outward.
