Latest Patents
Jaala's latest patents include a "Folded spiral seam including longitudinal bonding stitch" and a "Dryer screen in a paper machine." The first patent describes a seam structure for a drying wire, which is produced by reducing the thickness of the end portion of the drying wire and folding it double. This design incorporates a stitching method that secures the double wire portion together, ensuring durability and effectiveness. The stitching is sewn in parallel with the warp threads, positioned below the contact surfaces, and bonded with silicone or a similar adhesive material.
The second patent, the "Dryer screen in a paper machine," features two superimposed connected gauze structures. This innovative design includes a surface gauze layer and a bottom gauze layer, both of which have similar warp threads. The warp threads of the bottom gauze layer are strategically placed over the weft threads of the surface gauze layer, effectively bonding the two layers together. This design ensures that the actual lengths of the warp threads in both layers are equal, optimizing the performance of the dryer screen.
