A hose assembly (24) suited for delivering viscous material to a dispenser nozzle (12) at a controlled viscosity and temperature. The hose assembly (24) includes a jacketed hose including an outer hose (34) positioned around an inner hose (36) carrying the mastic and defining an annular passage between the inner hose and the outer hose, and a hose cover assembly (29) adapted to be releasably wrapped around a further remote hose carrying the mastic. The cover assembly (29) includes an elongated strip of flexible material including generally parallel opposite longitudinal edges; a plurality of tubes (80) embedded in the strip and running longitudinally through the strip; and coacting interengageable quick release means (88) such as a zipper on the opposite longitudinal edges of the strip to enable the strip to be wrapped around the hose and secured in position around the hose by releasable interengagement of the quick release means.

L'invention concerne un tuyau flexible (24) servant à acheminer un matériau visqueux jusqu'à un ajutage distributeur (12), à une viscosité et à une température régulées. L'ensemble tuyau flexible (24) comprend un tuyau flexible chemisé comportant un tuyau flexible extérieur (34) situé autour d'un tuyau flexible intérieur (36) qui transporte le mastic et définit un passage annulaire entre le tuyau flexible intérieur et le tuyau flexible extérieur. L'invention concerne également un ensemble enveloppe (29) qui peut être enroulé de manière amovible autour d'un autre tube flexible éloigné qui transporte le mastic. L'ensemble enveloppe (29) comprend une bande allongée de matériau flexible présentant de manière générale des arêtes longitudinales parallèles opposées. Une pluralité de tubes (80) sont intégrés dans la bande à travers laquelle ils s'étendent dans le sens longitudinal. Des éléments à attache rapide à engagement mutuel qui coopèrent (88) comme une fermeture à glissière se trouvent sur les arêtes longitudinales opposées de la bande afin que cette dernière puisse être enroulée autour du tuyau flexible et qu'elle soit ainsi maintenue en position autour dudit tuyau flexible par engagement mutuel libérable des éléments d'attache rapide.
