High-Pressure Water Automatic Tail Cutter
The High-Pressure Water Automatic Tail Cutter represents a major breakthrough in dry-end cutting. Developed to provide a cleaner, more efficient method of cutting tails in the dry end of the paper machine, this innovation utilizes ultra high-pressure waterjets in place of a blade. Since there are no knives to become dull, the tail cutter delivers a dust-free, drag-free cut that results in reduced downtime for thread-ups. The waterjet technology also increases productivity by delivering high cutting speeds and eliminating the downtime associated with blade changes. Additionally, the low cutting force exerted by the waterjet on the web results in stronger sheet edges and fewer web breaks.
Kadant Web Systems' waterjet technology is the result of extensive research
and development. By operating at 15,000 to 40,000 psi, it offers several distinct
advantages over blades:
- The water needle jet cannot become dull or blunt like a blade.
- It does not require physical adjustments.
- As the waterjet has virtually no width, it can travel across a moving web at high speeds without disturbing or breaking the sheet.
- Airborne dust is eliminated, reducing housekeeping chores and enhancing paper quality.
- The waterjet exerts a low cutting force on the web. As a result, cutting is faster and smoother, reducing cross-machine cutting time and improving the efficiency of tail transfers from section to section.
- Waterjets produce sharper and stronger sheet edges than a knife or rotary blade. In addition, the waterjet can cut a full line of paper products, from chipboard to tissue. Coated stock can be cut without edge cracking.
The four-point contact of the V-rollers to the V-rail assures stability and precise positioning, as well as allowing for easy movement of the tail cutter carrier.
