Core-cutting knives are precision tools used in a variety of sectors for cutting different materials such as paper, cardboard, labels, adhesive tape and film,
as well as plastics, non-woven, fabrics and special materials.
In the paper and cardboard industry, core-cutting knives are often used to cut rolls of paper or cardboard into more manageable sizes.
In other words, they are designed to provide a clean and precise cut, minimising the effort required and increasing the efficiency of the production process.
In addition, they are built with high-quality materials to ensure durability and wear resistance, making them ideal for use in industrial environments.

Perfection in every detail
To obtain a precise and high-quality cut, Negri Lame offers circular knives and core-cutting knives with a bevel geometry adapted to the size and thickness of the cardboard core.
Not only that, the centrality of the edges of the knife is also a key factor for maximum efficiency and durability.
In addition, Negri Lame’s high-speed steel core cutting knives guarantee a significantly longer service life than traditional cold-processing steels, thanks to their exceptional wear resistance.
Punching station: efficiency and speed
The cut belts can be fed to one or two winding shafts, as necessary.
The length of the cardboard tubes is synchronised with the set cutting width, ensuring a smooth and precise process.
In addition, the motorised knife holders and the automatic blade adjustment system ensure maximum cutting precision.
In addition, the freely-selectable correction dimensions allow the machining to be customised according to specific needs.
With the drilling station, the pneumatically-operated knife holders, equipped with sharp blades, rotate together with the cardboard tube, guaranteeing longitudinal cuts and separation of the tubes in a very fast time.
