Document Type and Number:
Japanese Patent JPS6252705
Kind Code:
B2
Abstract:
An apparatus which alters the specifications of a corrugated fiberboard sheet produced from the double facer of a corrugating machine. A rotary shear cutter (1) is disposed downstream of slitter scoring units (2a, 2b) for scoring the corrugated fiberboard sheet. Since the corrugated fiberboard sheet is cut at the downstream side of the slitter scoring units (2a, 2b) when the specifications of the corrugated fiberboard sheet are altered, the end of the sheet thus cut is not engaged with the inlet of the slitter scoring units. It is not necessary to decelerate the operating speed of the corrugating machine even when altering the specifications of the corrugated fiberboard sheet.
