With two patents to her name, she has developed techniques that enhance the efficiency and effectiveness of papermaker's fabrics used in the industry.

Latest Patents

Bodil Jonasson's latest patents reflect her commitment to improving papermaking technology. The first patent is titled "Seam for Multiaxial Papermaking Fabrics," which details a method of seaming an on-machine-seamable multiaxial papermaker's fabric designed to prevent yarn migration. The method involves creating an endless loop of multiaxial fabric, which is flattened into two layers along fold lines. By removing cross-direction (CD) yarns from the folds, extended ravel areas are created, allowing for the formation of seam loops from unbound machine direction (MD) yarns. The innovative use of affixed CD materials along the edges of these ravel areas helps keep CD yarn tails from migrating into the seam area.

Her second patent, "Ultrasonic Seaming of Abutting Strips for Paper Machine Clothing," introduces a novel manufacturing method for papermaker's fabric. This technique involves spirally winding a woven fabric strip, which is narrower than the intended width of the fabric. As the fabric strip is wound, a lateral fringe of unbound ends of crosswise yarns extends beyond the edge, allowing for a seamless connection through ultrasonic welding or bonding with adjacent turns. This results in a high-quality, spirally continuous seam that significantly enhances the durability of the fabric.
