Doctoring systems
engineering GOOD DOCTORING IS ESSENTIAL FOR EFFICIENT PAPERMAKING! The proper design and application of a doctoring system can improve the performance of your paper machine. BONETTI doctoring systems, are custom designed to meet the deflection and natural frequency requirements for a particular machine width, speed and roll diameter. Engineering at BONETTI is supported by the most advanced software available on the market. We perform finite element analysis (FEA) to accurately model our products to determine structural integrity, performance and reliability, as well as predict structural failures. BONETTI beams are stress relieved and machined in the intended working position, to remove the natural deflection present in the structure after fabrication. BONETTI troubleshooting team is available for field machine reports, maintenance and improvements to increase doctoring performance and blade life, as well as for installation supervisions. 1.4265852e+000 1.3820044e+000 1.3374236e+000 1.2928428e+000 1.2484620e+000 1.2036812e+000 1.1591004e+000 1.1145197e+000 1.0699389e+000 1.0253581e+000 9.8077729e-001 9.3619651e-001 8.9161572e-001 8.4703494e-001 8.0245415e-001 7.5787336e-001 7.1329258e-001 6.6871179e-001 6.2413101e-001 5.7955022e-001 5.3496943e-001 4.9038865e-001 4.4580786e-001 4.0122707e-001 3.5664629e-001 3.1206550e-001 2.6748472e-001 2.2290393e-001 1.7832314e-001 1.3374236e-001 8.9161572e-002 4.4580786e-002 0.0000000e+000 Contact us TODAY, and we will work out the best doctoring solution for your needs! bonfiflex super Heavy duty self conforming tube loaded blade holder fabricated in stainless steel AISI 316L.

Established in 1923 Bonetti has been successfully supplying the pulp and paper industry since more than 50 years. The renown reliability and quality of coater blades gave rise to the first requests for doctor and creping steel blades in the late 1960 s. Synthetic-material doctor blades became available in the 1980 s. Challenged by ever-changing doctoring technology, Bonetti has then successfully developed hi-tech materials to meet specific Customer needs. In the mid-1990 s Doctoring and Creping Systems were a natural addition to the Bonetti Product lines. High-quality Doctor Holders, Systems and Spare Parts, with innovative design features have since been manufactured and installed throughout the world. To meet worldwide product demands, four (4) new manufacturing facilities were inaugurated in the 1990 s and 2000. Sturtevant, WI USA; Hagen, Germany; Cantalupo, Italy; Trois-Rivieres, QC Canada; now complement world headquarters in Lainate, near Milan in Italy. Bonetti s success has always been based on a timely response to the needs and demands of the markets it serves. For more than 50 years, and now in the third generation of family ownership, Bonetti has been and will continue to be a global partner of paper mills and paper-machine manufacturers worldwide. www.bonetti.com ITALY BONETTI S.p.A.
