Kadant products are used in various web processing applications such as coating, laminating, and printing to ensure rolls are kept clean, maximum cooling or heating is achieved, and curl is controlled. New technologies in rotary unions and sealing devices, paper curl control, and roll cleaning systems increase process efficiency, product yield, and plant productivity to help companies to be more sustainable in their operations.
Kadant doctor blades are used to clean rolls and remove stock accumulations, water, pitch, and filler buildup. Produced using more than 27 standard and advanced materials, Kadant blades have earned a reputation for precision, efficiency, and reliability.
Kadant delivers a high level of control with curl and moisture control systems. The feature that enables both the Steam-Foil™ and the Narrow Web DeCurler™ profiling systems to provide high levels of moisture and curl control is its patented Coanda® nozzle. The Coanda nozzle, derived from Kadant’s floatation dryer experience, has been utilized by the paper, converting, and printing industries for more than 25 years.
A rotary union is a rotary sealing device that connects rotating equipment to fixed piping for the transfer of steam, water, thermal oil, coolant, hydraulic oil, air, and other media. Rotary unions can be designed with multiple passages and manage multiple media types simultaneously.
