Title:
CONTROLS FOR PAPER, SHEET, AND BOX MANUFACTURING SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2019/014539
Kind Code:
A3
Abstract:
Systems for providing manufacturing of sheet or box structures, corrugate sheets, or other products of varying size and structure, optionally with pre-applied print ("pre-print"). The systems include automated control of the corrugator, including the knives, slitters, scorers and cut-to-mark detection system(s). Colored markings are 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. Computer readable markings enable checking of the actual position in the roll plan to an intended position, enabling stopping or changing of the corrugator operation if needed.
