ABSTRACT:
An apparatus comprising a hollow cylindrical member rotatably supported on a shaft, a plurality of guide bars mounted on the cylindrical member as arranged radially therearound and slidable axially thereof, and an annular guide plate supporting one end of each guide bar by a roller so that zigzag travel of a running sheet can be corrected by the axial sliding movement of the guide bars due to an inclination of the guide plate and by the revolution of the guide bars around the shaft. The support point for the inclination of the guide plate is shiftable toward or away from the apparatus.
