Abstract
Systems for providing efficient manufacturing of sheet or box structures, corrugate sheets, or other products of varying size and structure often with pre-applied print (“pre-print”) are provided herein. The systems include various features and modules that enable automated control of the corrugator, including the knives, slitters, scorers and cut-to-mark detection system(s), are contemplated. Colored markings may be used to indicate an order change section between two order sections of a roll plan for the manufacturing process. The colored markings are detected as the corrugator runs and, once detected, a controller determines a next set of order instructions—e.g., to match the upcoming order. Thus, an order change may occur, thereby enabling automated control of the corrugator based on the new order instructions. Computer readable markings may enable checking of the actual position in the roll plan to an intended position, enabling stopping or changing of the corrugator operation if needed.
