Polyurethane roll cover launched by Voith


A


high-performance roll cover made from polyurethane (PU) has been launched by


Voith. To positively influence paper


characteristics like printability, coating and starch are applied to the paper in the coating and sizing section using applicator units. Voith’s SupremeFilm roll cover is said to work well in the Voith Speed Sizer AT, and is also suitable for challenging applications in


film presses produced by other manufacturers. “For years, PU roll covers have


been successful high-end solutions for the press section,” explains Ralf Moser, global product manager for the finishing section at Voith. “We are now exploiting the excellent qualities of this material, which we have adapted specifically to the requirements of the film press.” SupremeFilm is said to offer a homogeneous and constant film transfer and retains its surface


roughness throughout its entire service life. This is due to a filler material that ensures ideal application for paper grades with high quality specifications. The PU material is also highly abrasion- resistant, which results in longer grinding intervals and consistent profile 2-sigma values. Sappi’s Ehingen paper mill was


one of the first customers to use the new roll cover in a film press. “We aim to be constantly


Sappi Ehingen mill manager Dietmar Muser is “convinced” of the value of SupremeFilm


evolving and continually making our production more efficient. To enable this, new technologies


were necessary. This was also the reason why we opted to use a promising new development with Voith,” says mill manager Dietmar Muser. “And this paid off, as the already very good results got even better. SupremeFilm allowed us to keep the 2-sigma profiles constant over an unprecedented installation period. This means that we achieved our main goal of producing perfect paper quality. In addition, we benefited from reduced maintenance costs and a longer run time between roll changes.”


Tool that more accurately measures paper bale quality


Dealers in the recovered paper (RCP) industry are the target for BaleVision, a quality assessment tool that provides comprehensive data so that buyers can maximise supplier performance and sellers earn a fair price for their product. Until now, the industry has had


limited options for measuring RCP quality. Conventional measurement methodologies


– such as ocular inspections and bale breaking – can be costly, labour intensive and highly subjective. Furthermore, any data collected is often unreliable and provides very little information for business decision-making and process optimisation. BaleVision overcomes these


limitations with a device for effective quality measurement


and a system for data analysis and visualisation. The quality assessment tool analyses the bale from the inside out, collecting detailed data on fibre content, moisture, plastic, ash and other bale contaminants. The tool has been


developed by merQbiz, which has partnered with the manufacturer, PTS, to be the exclusive distributor in North


America. “BaleVision is an industry-


first solution that gives sellers insights into the real value of their paper and enables mills to proactively optimise procurement and operational processes,” said John Fox, chief executive of merQbiz. “There’s nothing like it in the industry that can deliver this level of value.”
