Circular knives for the cutting of toilet paper rolls and cardboard

The winning idea of the founders was to create a single factory containing all the machinery required to complete the entire manufacturing process on the same site, thus enabling Julia to monitor and develop every individual part of the process, from the quenching and tempering of the steel plates, to the sharpening and eventually PVD coating of the discs. The growth of Julia Utensili has been possible because of the constant activity and innovation of the R&D department, in connection with its fully equipped metallographic laboratory, and the recently acquired Scanning Electron Microscope (S.E.M.) with Energy Dispersive X-ray Spectrometry (E.D.X.S.) instrument. That analysis capability allows the R&D department to extensively research every part of the process, studying new solutions and materials. In addition, Julia collaborates with specialized universities and research laboratories, both in Italy and abroad.

The company’s quality system is certified in accordance with UNI EN ISO 9001 international standards, which ensures a constant qualitative monitoring of all phases of the production cycle. Julia Utensili imposes strict process control standards on 100% of its products to ensure high quality every time.

More than 40 years of ongoing experience ensure that we always supply the best tool to fulfil our customers’ exact needs

Thanks to a capillary distribution network Julia Utensili is present worldwide, and the company’s highly qualified staff provide superior technical support wherever necessary.The company has 40 years’ experience in the production of high quality knives for cutting various materials, and in 2013 Julia Utensili enlarged its product range, focusing on circular knives for the cutting of toilet paper rolls and cardboard. These special knives are the result of an extensive study of the cutting process of toilet paper carried out by Julia’s R&D department, together with the biggest producers of tissue machines.

The firm goal was to develop an innovative knife able to perform exceptional clean cuts at a high production rate, together with a long tool life. Now the company is happy to offer a product which can reach this target. The production process starts with the dedicated heat treatment, quenching and hardening of the steel plates. Specific furnaces perform these treatments under constant monitoring: the result is a stable and homogeneous steel structure, which provides the correct hardness and reduces deformations on the discs. The grinding process has been optimized to reduce the surface roughness to a minimum. The super-smooth surface and the special profile of the cutting edge are both very important in reducing the friction that generates heat during the cut – the main thing responsible for blade wear. Julia Utensili’s knives have very low axial and radial run out, checked on 100% of production, to provide the correct stability during the cut, even if the temperature in the cutting area increases – another important prerequisite for obtaining a good finish and a long saw blade life.

These blades are designed for high speeds, up to 300 strokes per minute, to cut toilet paper, kitchen paper, and many more tissue items on the following tissue saw machines: Fabio Perini, PCMC, Futura, Italconverting, Gambini, Bretting, Kawanoe Zoki, Bao Suo, Dechangyu. Julia Utensili can also offer the correct grinding wheels for all types of machines to grind our high-hardness knives.
