Conditioning for flatness and antistatic
Shortening production times, preserving resources
Composites such as textile/foil, foil/foil or textile/non-woven bonded with one-component polyurethane adhesives normally require moisture from the ambient air for curing. This process is time-consuming and difficult to verify. The challenge consists of moistening the material web after the bonding process exactly enough for the adhesive to cure quickly and positively without having to remove excess liquid or for additional drying.
Exact wetting lets the adhesive cure immediately, intermediate storage is not required and the periods between production steps are shortened. Wetting also has a positive effect on product quality when material webs run through an intensive drying process.
Non-contacting liquid application
With WEKO-Fluid-Application-System (WFA) such as WEKO-FLOW or WEKO-BASIC , each with WEKO-SIGMA rotor carriers, liquid for the conditioning of the material web can be applied in exact amounts. This saves valuable resources, provides you with much flexibility and ensures consistent, reproducible product quality. The WFA can be quickly adapted to different applications and product formats.
