Paper cutting & slitting
Waterjet cutting with pure water is the ideal solution for the cutting and slitting of paper and plastic webs as well as cardboard panels. The technology is already widely used in the production of wallpaper and packaging material. The most common machine used in this field is called a slitter, which is a longitudinal cutting machine equipped with one or more pure water cutting heads. The material to be cut is transferred on a conveyor and is cut by the cutting heads located above the belt. In contrast to cutting with roller blades, the material is not shifted and there is no dust produced in the process. As the material is in contact with the waterjet for only a split second, its quality is not affected. The method is also suitable for the cutting of several layers of material. In this case, the operator must ensure that there are no cavities between the layers where water could collect.
Main advantages of paper cutting with waterjet:
- No waste of material
- Maximum flexibility as regards production processes
- No need for resharpening the tool
