<p><P>PROBLEM TO BE SOLVED: To provide a roll paper core hole correcting apparatus capable of correcting a core hole with the roll paper in a log-cut state. <P>SOLUTION: The roll paper core hole correcting apparatus includes a conveyor line for conveying core-less roll paper in the axial direction of the core hole; a lifting mechanism for lifting a plurality of conveyed paper rolls from the front end of the conveyor line to linearly match the core holes; and a correction shaft inserting mechanism for inserting a correction shaft narrower than the core holes into the core holes of the paper rolls lifted by the lifting mechanism, and reaming the correction shaft after inserted for correcting the core holes. With this structure, the core holes can be corrected with the log-cut roll paper as it is, and the shape of the core holes can be easily changed according to the diameter of the roll. Further, as the correction shaft is inserted in one direction, and as the narrow shaft expands after insertion, the defective correction of core holes can be reduced. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
