ABSTRACT:
An apparatus for modifying a traveling position of a paper web in a paper web processing machine is provided. The apparatus is capable of easily attaching a detection means; requiring no operation of the paper web processing machine to determine an accurately adjusted position for attachment; and extremely easily setting a desired size of a tolerable deviation range of a practical position of a side edge to an originally expected position of the side edge when the sheet travels. The apparatus includes a traveling position modification means for modifying a position of a side edge of a paper web traveling toward a processing section in a paper web processing machine; a detection means for detecting the position of the side edge of the paper web; and a control means connected to the modification means and the detection means for controlling the modification means based on a value detected at the detection means.
