Abstract:
1. A method of selecting cutting and skiving patterns to be used in the production of product rolls from at least one master roll, the product rolls having widths ordered by customers, the method implemented by a processing system, the method comprising: selecting those of the ordered widths that are suitable for skiving, wherein the selection of ordered widths is based on a first constraint; selecting auxiliary widths based on the selected ordered widths and on a width of the master roll, wherein the selecting of auxiliary widths is further based on a second constraint; generating skiving patterns that can be used to join the selected auxiliary widths to form the skived rolls and to form auxiliary rolls based on the auxiliary widths, wherein the generation of the skiving patterns is based on a third constraint; generating cutting patterns that can be used to trim the master roll to form the product rolls, wherein the generation of the cutting patterns is based on a fourth constraint; and, selecting those of the generated skiving and cutting patterns that optimize trim efficiency.
