Abstract: The invention relates to a method for coating a textile hose (4) with a thermoplastic sealing material (5), in particular polyurethane-based, in a coating device (2). 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, in particular formed from a tubular knit hose; the textile hose (4) is fed to the coating device (2) and is continuously drawn onto a mandrel (6) extending in the longitudinal direction and approximately in the vertical direction (8) and is continuously transported further over this mandrel (6), the mandrel (6) being supported and oriented according to the position by at least one support means (10) provided outside the textile hose (4).
