A patent application (Publication Number: US20240033986A1) describes a method for coating a textile hose with a thermoplastic sealing material in a coating device. The method involves feeding the textile hose onto a mandrel, continuously transporting it over the mandrel, and applying the thermoplastic sealing material to the outer circumference of the hose. The material penetrates into the hose, forming a closed superficial coating. The coated hose is then drawn off the mandrel. Additional steps include transferring the coated hose for storage or further treatment, cooling the coated hose, and using support means such as support rollers to stabilize the mandrel during the coating process.
Furthermore, the patent application details a coating device for implementing the method, which includes an elongated mandrel, a feeding and transporting device, a mechanism for applying the melted thermoplastic sealing material, and a draw-off device. The device may also feature components for transferring the coated hose, cooling the coated hose, and supporting the mandrel. Various configurations of support means, such as support rollers and a ring element, are described to ensure the stability and proper positioning of the mandrel during the coating process. The device is designed to efficiently coat textile hoses with a uniform surface weight of thermoplastic sealing material, potentially enhancing the durability and performance of the hoses in various applications.
