A paper edge trim unit can be a crucial step in the paper-making process, as it allows for the removal of poor quality or cracked edges and uneven edge moisture, as well as the production of steady and precise web widths at any point along your online or offline processes. Additionally, the waste generated during the trimming process can be efficiently returned directly to the nearest pulper or remote broke chest, minimizing waste and maximizing resource utilization.
A paper edge trim unit is a highly effective solution for creating a high-quality and fixed edge in the cross-machine direction, overcoming the challenges posed by the sideways-moving web. By utilizing the Trim-Jet™ P edge trim unit, you can wind rolls with a perfect edge and prevent coating materials from seeping through gaps, thereby avoiding contamination on the other side of the sheet or its backing during coater application. Furthermore, the Trim-Jet™ P maintains a fixed edge through calender and supercalender, reducing heat stress on the roll cover and eliminating uneven sheet edge caliper.
Features | Paper Edge-Trimming System
- Cut paper sheet edge trims as small as 15mm (0.6”) and up to 150mm (6”) or higher
- Can handle and convey paper edge trims using compressed air or a blower fan
- Stainless steel construction
- Diamond cutting nozzles for reliable jets and long-life
- Can be installed where ropes are present
Advantages | Paper Edge-Trimming System
- Able to engage into any sheet edge quality to initiate any pre-set trim removal width
- Can effectively trim an oscillating sheet to produce a high-quality fixed-edge
- Eliminates forming paper edge defects that may lead to sheet breaks
- Not affected by sheet speed, moisture, caliper, or tension
ROI
- Able to sustain narrow trim down to 15mm (0.6″) for maximum product on the reel
- Production costs are significantly improved as only rolls with hole defects or requiring splicing must be re-reeled
- Increased machine speed
- Sheet edges are directed to the machine pulper, bypassing any broke chest
