IBS Paper Performance Group （IBS-PPG） propose a new approach to wet-end optimization by combining its existing wet-end optimization technology of iTABLE® system with newly developed high-speed camera monitoring system for wet-end activity control. iTABLE® consists of 1） Flexible forming board in MD position, 2） Height and angle adjustable blades in dewatering boxes, 3） Vacuum control valves, 4） Control Unit, and 5） On-line dryness sensor. These are all targeted to improve sheet formation and operational flexibility in sheet forming zone of wet-end. IBS has delivered over 200 systems of iTABLE® all over the world with benefits of improved sheet formation, reduction in basis weight, machine speed-up, refining energy saving, sheet strength improvement, and reduction in chemical usage. IBS has also recently developed a high-speed camera monitoring system for various wet-end activities. TableVision® system involves different sets of camera and software to monitor and control important aspects of wet-end activities. JetVision monitors jet impingement point by measuring the length of jet cut-through of stock to maintain a proper position of forming board. ActivityVision monitors and quantifies fiber activity with cameras set along forming table. FlocVision monitors and quantifies sheet formation by measuring the size of fiber flocs. With two different set of LED lighting, it can observe both topography and sheet formation. LineVision monitors dry-line position to control proper vacuum level.
This new approach for wet-end optimization with a combination of flexible iTABLE® system and visual online-controllable TableVision® would provide paper makers with competitive advantages, operational flexibility and means to overcome human resource shortages. This combined system has been delivered to over 50 customers with significant benefits such as improved sheet formation, conversion from fresh pulp to recycled pulp and reduction of B-grade products and rejects.
