Latest Patents

Ishikawa holds a patent for a crimping apparatus that enhances the production of filamentary strands. The apparatus operates by ejecting a thermoplastic filament from an ejection nozzle, which is then entrained on a heated medium flow into a stuffing chamber. This chamber is structured on a circulating endless surface that moves at a speed slower than the ejection speed. As the filamentary strand is transported, it is gradually compressed, resulting in a product with random, bulky, and round three-dimensional crimps. The process also incorporates either free or positive cooling during transportation, ensuring the quality of the final product.
