Controlling Board Quality The quality of corrugated board is affected by many factors – the equipment, raw materials (paper and starch) and process conditions. Equipment and raw materials are best handled by plant management and are considered to be uncontrolled variables. These process conditions are controllable with a quality control system. |
The quality control system will preset the corrugator – heat (preheater wraps doublefacer loading), starch application gaps, auxiliary moisturizers, bridge accumulation – for the grade of board to be produced when a paper change takes place. It will then adjust the settings as the speed of the machine changes to ensure that the appropriate amounts of heat and starch are being applied at all speeds and conditions. Measurements of paper temperature and moisture are used as a feedback mechanism for finer continuous adjustments. This will ensure the production of quality board at all times. Page |
