Abstract:
An order changing method in a corrugating machine comprising a slitter scorer device and a plurality of cut-off devices, the method comprising the steps of:cutting an old order corrugated fiberboard web along slitter cutting lines in a running direction thereof by the slitter scorer device; dividing the cut old order corrugated fiberboard web into at least two portions by using, as a boundary between the at least two portions, a dividing slit which is one of the slitter cutting lines wherein the dividing slit does not coincide with a centerline of the old order corrugated fiberboard web; feeding the divided old order corrugated fiberboard web portions to the cut-off devices; cutting and separating each of the old order corrugated fiberboard web portions thus divided in a direction orthogonal to the running direction thereof by the cut-off devices; supplying a new order corrugated fiberboard web subsequent to the old order corrugated fiberboard web wherein the new order corrugated fiberboard web has a width different from a width of the old order corrugated fiberboard web and a dividing slit that does not coincide with a centerline of the new order corrugated fiberboard web; and substantially aligning the dividing slit of the old order corrugated fiberboard web with the dividing slit of the new order corrugated fiberboard web.
