Nonwovens are extremely versatile and are therefore used in an increasing number of applications. In order to further adapt their performance to the specific conditions of use, they are often given a functional finish or refinement.

This can either be applied during fiber preparation or subsequently. The great advantage of a subsequent finishing is that even smaller batch sizes can be produced cost-efficiently and the quantities of finishing chemicals can be significantly reduced.

For this purpose, the WEKO Fluid Application System (WFA) offers a sustainable and contactless minimal application solution. Whether single-sided, double-sided or different functions on both sides - just as required.

Working widths of up to 7.5 meters and web speeds of over 1,000 meters/minute are easily available. The non-contact rotor spray skin application enables uniform application quality across the entire web width and avoids contamination of the application liquor/chemicals.
Depending on the requirements and intended use, very small quantities of liquid can be applied in a speed-compensated manner. In many applications, this saves considerable drying capacity, but in any case a large proportion of the spray medium.

Consisting of a selectable fluid supply and system control WEKO-BASIC or WEKO-FLOW as well as the application module - a rotor carrier WEKO-SIGMA or WEKO-ProTec - dispense finishing fluids precisely and reproducibly at the touch of a finger.

WEKO-ProTec ensures a clean production environment. Here, the rotor carriers operate in an encapsulated housing. The connected extraction system ensures that harmful aerosols are prevented from escaping. Contamination of the working environment is effectively prevented.
