Toscotec successfully accomplished an extensive rebuild of Russian containerboard manufacturer JSC Yarpaper’s PM1 at their mill in Yaroslavl, near Moscow. PM1 has a wire width of 2,830 mm and produces 100% recycled-based fluting and test liner in the range from 90 to 175 gsm.
The rebuild has optimized the entire paper machine, from the approach flow system to the dryer section, and has achieved the targets of production increase and quality upgrade.
The scope of the rebuild included the approach flow system, with screens, fan pumps, a TT Headbox-H equipped with TT D-Profiler dilution control system, a newly designed Fourdrinier make up, and the optimization of the sheet path in the press section.
Toscotec installed a completely new dryer section, fitted with 35 TT SteelDryers designed for 10 barg operating pressure, structural frame, canvas rolls, doctors, stabilization boxes, stretchers, guiding, tail threading system, oil lubrication unit, as well as mechanical drives for the entire line.
The project also included a complete service package with engineering, erection supervision, commissioning, start-up assistance, and training.
Igor Noskov, Project Manager of JSC Yarpaper, says, “We successfully completed a major rebuilding operation on our paper machine in difficult times during Covid-19. We have expanded our range of high quality containerboard papers to 90-175 gsm and have increased our reel width to 2,500 mm. This will allow us to better serve our Russian customers, and expand to Europe and the Middle East.”
Luca Nesi, Toscotec Start-up Engineer, comments, “The cooperation with Yarpaper was very good throughout the entire project. They provided the best conditions for Toscotec to work on site during the pandemic. We could thoroughly prepare the machine, so that at start-up we got paper on the pope reel shortly after sending stock to the new TT Headbox. It is a great satisfaction to witness the successful completion of such an extensive rebuild, where we newly designed or extensively rebuilt most sections of the paper machine to deliver a significant production increase.”
