Bonetti

ABOUT US

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.

DOCTORING AUDIT

Why optimize the doctoring system?
  • Because it has a direct impact on the efficiency of the machine, better doctoring efficiency equals greater machine
     efficiency
  • Higher machine speed
  • Fewer machine shutdowns
  • Fewer paper breakages
  • Because it can be an inexpensive way to increase machine efficiency: changing the type of blade requires neither investment
     nor financing
  • Because cleaner rolls produce higher quality paper
  • Because more sophisticated materials can reduce energy consumption
  • Because more sophisticated materials can mean longer life for the roll coatings
  • Because more sophisticated materials can reduce the cost of the blades per ton produced
  • Because fewer blade changes reduces the risk of accidents for the operators

Bonetti, with its specialists, can offer a complete audit of the doctoring systems and the blades in use.
For doctoring systems the audit includes a geometric check of the mechanical condition of the doctors.
For blades, the audit includes a check of all the blades used as well as an analysis of both existing wear and of wear pattern.

The detailed report is a photograph of the existing situation and highlights any inconsistency with best practice. The report also includes a priority list of actions to improve doctoring and to avoid this being a production bottleneck.
