Technology
Friese corrugated rolls are manufactured entirely in our facilities, produced using state-of-the-art equipment and resources, under controlled processes that guarantee compliance with assumed deadlines, process repeatability and the highest level of quality available on the market.
- Waldrich Coburg CNC grinding machine special for wave formation
- CNC lathes programmed for machining shaft ends and corrugated rolls finishing;
- Waldrich cylindrical grinding machine for finishing pressure cylinders;
- Heat treatment installations (induction tempering and nitriding furnaces);
- Surface coating installations (Rockwelle application);
- Balancer
- Welding station
- Laboratory with instruments and equipment for control and non-destructive testing
Friese corrugating rolls are polished on the most modern machines available, with the precision required for the application. Due to the computerized numerical control in our equipment, we operate with 10 µm cylindricity.
Advantages of our technology:
- Extended corrugated cylinders life
- High profile stability
- Reduction in paper consumption by 2 to 5%
- Increased resistance of the corrugator plate by up to 10%
- Low maintenance and service costs
- Profiles designed to increase physical testing on corrugated cardboard sheets
- Continuous production at higher levels of operation:
- High production speed
- Significant reduction of vibrations
- Reduced waste levels

Products
In 1996, Friese developed and introduced tungsten carbide coating, called ROCKWELLE®. With it, we can offer unique solutions in corrugated rolls, with optimized geometry that delivers better performance in paper consumption (less take-up) and physical tests, from the beginning until the end of the rolls’ life. From the manufacturing processes to the coating composition, ROCKWELLE® delivers a quality that is extremely different from the market.
Compared to corrugated cylinders hardened by the nitriding process, or those coated with chrome, ROCKWELLE® has a much longer useful life. We have a three-step polishing process that ensures low surface roughness compared to chrome plating (roughness Ra < 0.30 µm).
The development of the coating allowed the cost of corrugated rolls per linear meter to be reduced by up to 75%, meaning ROCKWELLE® offers a longer useful life and cost-benefit.
The graph below and to the right shows the coating thickness and service life of different corrugator corrugated cylinders surfaces. Compared to nitriding-hardened and chromium-coated corrugated cylinders, Rockwelle® shows a much longer service life, with practically no noticeable wear on the sides of the waves, guaranteeing the best performance of the finished product, throughout the life of the corrugated cylinders.
The fact that the profile of ROCKWELLE coated corrugated cylinders remains practically uniform throughout their useful life allows the profiles to be significantly optimized. The result is our ROCKPROFILE.
The starting point for optimization is the minimized tension in the labyrinth between the rolls during the corrugated cardboard forming process. In this way, it is possible to achieve constant quality and superior performance results for the corrugated cardboard sheet, that is, the operation is completely rationalized with lower consumption of corrugated board and test gains.
ROCKPROFILE is developed exclusively for each application. Individual parameters are considered, such as the type of Single Facer used, the quality level of the paper used, the production speed and cardboard box application. In this way, the proportion of corrugated board consumption can be significantly reduced, and also provide better resistance to the corrugated cardboard sheet, if the customer so desires.
Friese uses advanced technology to produce precise and durable creases, meeting the highest quality standards. A well-manufactured crease is crucial to guarantee the quality of the cardboard sheet’s finish, its structural strength, dimensional accuracy, production efficiency, reduction of rework and waste, and ease of assembly on a crease machine.
Additionally, we offer technical support and customization of solutions. Choosing Friese means choosing reliability, efficiency and excellence in the manufacturing of new creases.”

Services
At Friese, the grinding process for recovering corrugated rolls is carried out using the “monoflute” method, exclusive to the Waldrich machine.
Specific and exclusive design, considering the new diameter dimensions of the worn corrugator rolls to maintain the geometric characteristics of the original profiles, in order to ensure the same conditions as the new rolls in terms of their efficiency, paper consumption (take-up) and life useful.
Every grinding process reduces the diameter of the rolls. The grinding process developed by Friese reduces wear on the diameters of the rolls to a minimum, increasing the number of grinds.
The application of Tungsten Carbide in the creases is an innovative technology that offers greater durability and quality.
This wear-resistant, high-precision material increases crease life and improves sheet forming.
With advanced coatings, this technology reduces crease replacement costs, increases production efficiency and ensures high-quality final products.
- Assembly of the Corrugator Rolls in the Cassettes;
- Assembly of Bearings and Accessories;
- Installation and Start-up Monitoring;
- Support for Customer Problem Analysis;
- Optimization of profile geometry.
