Toscotec’s TT Headbox-SL starts up on BiOrigin Specialty Product’s MG machine in USA
BiOrigin Specialty Products started up PM2 at its Menominee site in Michigan after the successful completion of a wet section rebuild supplied by Toscotec on a turnkey basis. PM2 is a MG (Machine Glazed) machine producing specialty papers including MG grades and flexible packaging products.
The project started with an onsite survey by Toscotec’s technical team who identified the primary targets of the new design, in particular moisture profile and CD bone dry profile. BiOrigin Specialty Products (or ‘BSP’) selected Toscotec’s design solution, valuing the importance of a fully customized technical offer based on the analysis of the machine’s operating data.
The rebuild achieved its targets of remarkable enhancement of cross direction (CD) profiles of the paper sheet. In particular, the new TT Headbox-SL’s dilution control allowed to improve the bone-dry profile; an optimized jet distribution and jet landing led to the improvement of the moisture and basis weight (BW) profiles. The installation of dewatering elements with angle and height adjustable blades in the Fourdrinier section increased wire dewatering. As a result, the rebuild improved the machine runnability, delivered definite potential for future production increase and improved sheet formation on all produced grades both in absolute terms and across the machine width.
A turnkey rebuild
Toscotec supplied the approach flow system, a hydraulic TT Headbox-SL fitted with dilution control to ensure optimal profile control, and an upgrade of the Fourdrinier section. The turnkey supply of the rebuild included a complete service package with erection, erection supervision, commissioning, and start-up assistance.
Steve Michalko, BSP’s Vice President Technical Service, says, “The entire project went smoothly from inception to successful completion without any significant concerns. The start-up curve was literally hours, and we continue to see intended and unanticipated improvements. The solutions provided by Toscotec have eliminated previous operational constraints and positioned BiOrigin Specialty Products to improve both capability and productivity moving forward.”
Luca Ghelli, R&D Director at Toscotec, says, “Since the beginning of this project, BiOrigin Specialty Products and Toscotec’s teams have been working in sync toward a common goal with a strong feeling of reciprocal respect. This kind of approach is in itself a recipe for success. The very positive outcome of the rebuild is of course the icing on the cake.”
