Method for order changing in corrugating machines

摘要

Provided is an order changing method in a corrugating machine which can decrease the number of defective sheets generated during an order change and can continuously stack the sheets in a stacking portion of an upper-stage stacker. In the order changing method to be performed in the corrugating machine comprising slitter scorer devices (7a) and (7b) for cutting a corrugated fiberboard web (5) by slitter cutting lines (20) in a running direction thereof, and a plurality of cut-off devices (9) for dividing the cut corrugated fiberboard webs (5) into at least two portions by using, as a boundary, a dividing slit (M) which is one of the slitter cutting lines (20) and for cutting and separating each of the corrugated fiberboard webs (5) thus divided in a direction orthogonal to the running direction thereof, a dividing slit (Mx) of the corrugated fiberboard web (5) having an old order and a dividing slit (My) of the corrugated fiberboard web (5) having a new order are formed in such a manner that they are set on almost the same straight line.
