Flying wire corrugating roller - new production capacity and innovative products

[China Packaging Network] Friese's production capacity continues to grow. The new fourth workshop was completed in May 2014. The 1200 square meter workshop is now equipped with a new grinding machine. Bernardo Friese said, “The new machine has greatly increased our grinding capacity. It allows us to accelerate production, reduce delivery time, and help our customers in emergencies. We will continue to follow our strategy and use the latest production. Technology provides the best quality."

Friese offers special tungsten carbide coated corrugating rollers that they call Rockwelle®. Now thanks to this tungsten carbide coating, the company can provide corrugating rolls with different coating qualities and surface smoothness. “Our spraying techniques, coating formulations and quality assurance measures are all different,” explains Mr. Friese. “Our ROCKWELL-coatings coatings are sprayed by an HVOF-process process that is outstanding It is famous for its adhesion and wear resistance.” He continued, “In addition, we have developed Shine Rockwelle® with a special coating material and a multi-step polishing technology that can be produced with a chrome finish. Comparable - with a surface roughness of Ra < 0.1 micron. The smooth surface of ShineRockwelle ® brings great advantages to the customer. Customers report that with this new smooth surface, the surface of the roller is cleaner and the tension in the corrugation is more Smaller, longer drum life, highest speed when the machine is started, and higher board strength.”

Fri ese sales explained that “the corrugated type coated with ROCKWELLE® is almost always consistent throughout the life of the corrugating roller, which allows us to optimize the corrugated type considerably. The ROCKWELLE® is the result.”

The company claims that the key to optimization is to keep the tension of the web at a minimum while the paper is being formed in the tortuous path between the corrugating rollers. In this way, better board quality and web running performance can be achieved.

“ROCKPROFILE® is individually designed for each application,” said Mr. Friese. “Different parameters—for example, single-sided machine consumption, paper grade or production speed—are all considered. With higher board strength, the shrinkage can be significantly reduced, even though the shrinkage of the outer diameter due to regrind after wear of the corrugating roll is also considered in the optimization design of the crucible.Friese's products provide the best performance and save Customer cost."

The company's Conntrolle dCondensate System controlled condensate system (CCS) in combination with the Thermogrooves hot trough reduces the formation of condensate insulation films inside the corrugating rollers during operation. As a result, almost no cardboard warping occurred during production suspension. Advantages of the CCS/Hot Trough include: better heat transfer, higher production speed and better sizing; reduced waste during production restarts by greatly reducing the "banana effect"; reduced maintenance due to no need to adjust the condensate pipe .
