Do You Know What is Edge Trim Nozzle?

What is an Edge Trim Nozzle? And its Working Principle

Paper edge trim nozzle is a specialized equipment that uses high pressure water jet for paper cutting. It is mainly used in the forming and press section of the paper machine, and is used for processes such as cutting edges, trimming, paper feeding, and cleaning of paper sheet. The edge trim nozzle core principle is to form a high speed and stable linear needle shaped liquid column through precision nozzles, achieving precise and clean cutting of paper, while also possessing advantages such as high efficiency, safety, and automation.

The Function of Edge Trim Nozzle

Edge Trimming:   During the papermaking process, the edges of the paper sheet are precisely cut to ensure consistent paper width, avoid burrs or irregularities, and improve the quality of the finished product. ‌

Tail Cutter: After the paper machine starts or cutting paper, the paper is guided smoothly through the wire and wet parts by a high-pressure water column, replacing the traditional manual paper guiding method and improving operational safety and efficiency. ‌

Why The Paper Machine Need Edge Trim Nozzle?

On a paper machine, the edge trim nozzle is used to precisely cut and remove the uneven edges of the paper web after sheet formation.

During the forming and pressing process, the paper edges may become irregular, loose, or weak. The edge trim nozzle uses a high-pressure water jet to trim both sides of the paper web, ensuring clean, straight, and accurate edges.

How to Keep The Edge Trim Nozzle Working Efficiently ?

• Maintenance of Edge Trim Nozzle

Ensure that the edge trim nozzle is in good condition, as worn water needles can weaken the water flow and reduce the cutting effect. You can choose sapphire or ruby inlay to extend its service life.

• Choose Appropriate Water Pressure

Water pressure is a key parameter that determines cutting quality. The setting of water pressure needs to take into account various factors such as the weight of the paper, the speed of the production line, and the aperture of the nozzle.

• Use A Double Hole Trim Nozzle to Spray

Using a double hole nozzle allows for the simultaneous use of multiple smaller diameter water streams. This can not only achieve cleaner cutting, but also reduce the amount of water required for this operation.

SUN HONG edge trim nozzle have single hole or double hole, stanless steel 304/316, brass, ceramic or ruby inlay for your choose.
