Abstract (en)
[origin: US5092833A] The paper folding machine is provided with a roller pair (T1,T2) which forms an intake zone (E) and determines the velocity of feed of the material to be folded, and with at least one pair of folding rollers (W1,W2,W3), which forms a folding zone (F1) and is parallel to the former pair of rollers. A stopless feed limiting device, which determines the actual folding length and can be actuated individually for each folding operation by a microprocessor and/or an electronic control circuit as a function of a feed measuring unit, is arranged in a material feed path (4) which extends past the folding zone (F1,F2). In order to reach narrow folding length tolerances even at high working speeds, on the side of the maerial feed path (4) opposite the folding zone (F1,F2), the feed limiting device is provided with a knife-like or bar-like deflecting member (6), which extends over the width of the material feed path and can be moved toward the folding zone (F1,F2) at a velocity corresponding to the velocity of feed of the material to be folded, while the material to be folded is deflected to form a fold.
