ABSTRACT:
A cut edge position correcting apparatus is used for correcting a direction and a wave-like contour of a cut edge of a belt-shaped member cut by a cutter unit. The cut edge position correcting apparatus includes a support base for supporting a belt-shaped member, a bending member arranged extendible above and retractable into the support base for bending the cut edge portion upwardly, and a restraining member rotatable in a horizontal plane for uriging the belt-shaped member over its entire width against the support base. The apparatus further includes a lifting unit for raising and lowering the restraining member, clamp pawls for clamping the cut edge portioned, a plurality of slide plates arranged aligned with each other in a lengthwise direction of the restraining member to hold the cut edge portion over their entire widths in cooperation with the clamp pawls, and a driving unit for independently moving said slide plates relative to the restraining member. With this arrangement, cut edges can be corrected in a manner that directions of the cut edge portions clamped by the clamp pawls and the slide plates are modified by rotating the restraining member and the wave-like contours are reformed by vertically moving the slide plates.
