Manufacturing flat, air-permeable material with adsorbant properties involves application of melt adhesive points

摘要

After the application of the adhesive points on the air-permeable material, the material is loaded evenly with granular or spherical adsorbents. The material is guided through a calender in which the adsorbents are pressed against the adhesive points. The non-adhering surplus is sucked off at the calender exit.
