ProJet’s High Pressure Tail Cutter in operation
Water-jet nozzles have ruby tips, with typical sizes between 0.05-0.60mm. Customers that have these High Pressure Tail Cutters installed, immediately notice the reduction in dirt and dust build up in the cutting area, which A. Leads to a cleaner and healthier working environment for operators and B. Maximizes reliability of the Tail Cutting and Tail Threading procedure on a paper machine. No vacuum or dust bag are required so maintenance is minimized and fire hazards are eliminated.
Power Cleaner in operation
The Power Cleaner cleans the Dryer Fabrics continuously, 24 hours a day, as long as the machine is running. Older technologies are operated in batch cleaning mode, allowing the dryer fabrics to get dirty first, loosing permeability, and then trying to restore that permeability again. This leads to uneven permeability profiles over time, mostly leading to paper quality issues and more broke. The advantage of continuous cleaning are a more stable moisture profile, less broke and longer lifetime of fabrics. Dryer fabric contamination is on the rise due to the increasing use of secondary fibers, recycling of coated broke, increasing use of sheet fillers, an increased use of recycled mill water supplies, and the increased use of process chemicals.
The equipment is scheduled to be delivered in Q4, 2021 and installation & start-up in Q1, 2022
