Method for coating a textile hose with a thermoplastic sealing material

A method for coating a textile hose (4) with a thermoplastic sealing material (5), in a coating device (2), wherein the textile hose (4) has a longitudinal direction and a circumferential direction and is manufactured continuously in the longitudinal direction and in the circumferential direction, and,

• wherein the method comprises:
• feeding textile hose (4) to the coating device (2);
• drawing the textile hose (4) in a transport direction (34) onto a mandrel (6) extending in the longitudinal direction and approximately in the vertical direction (8);
• transporting the textile hose (4) further in the transport direction (34) over the mandrel (6), wherein the mandrel (6) is supported and oriented by at least one support means (10) provided outside the textile hose (4),
• providing thermoplastic sealing material (5) in a heated flowable state;
• feeding the thermoplastic sealing material to an outer circumference (38) of the textile hose (4) which is transported over the mandrel (6) in such that some of the thermoplastic sealing material (5) is capable of penetrating into the textile hose (4) and/or is capable of adhering to the outer circumference (38) of the textile hose (4) and forms a closed superficial coating thereon;
• and,
• drawing the coated textile hose (4) in the transport direction (34) and over a support body (16) of the mandrel (6) and from the mandrel (6);
• wherein the support means (10) comprises a pair of support rollers (12), and the mandrel (6) is arranged to extend above the pair of support rollers (12), the pair of support rollers (12) configured and dimensioned to operatively engage the support body (16) of the mandrel (6) to absorb a weight force of the mandrel (6) to at least partially support the mandrel (6) in the longitudinal direction and/or a vertical direction within the coating device (2);
• and
• wherein the support body (16) defines a tapered or curved surface and terminates within a complementary curved or tapered gap (14) defined between the support rollers (12);
• and
• wherein the tapered or curved surface of the support body (16) and the complementary curved or tapered gap (14) of the support rollers (12) are configured to transition the coated textile hose (4) to a flattened state for storage.
