ABSTRACT:
The invention relates to a hose that comprises at least one inner layer (1) produced from an elastomer material, an embedded reinforcement carcass produced from a textile and/or metal material, an outer layer produced from an elastomer material and a coupling having a flange section inside the hose end. The inventive hose is characterized in that the coupling comprises a fitting, a supporting flange and at least one annular lamina. A first reinforcement carcass, consisting of at least one reinforcement layer, extends along the entire inside of the fitting and changes in the flange area from the axial to the radial direction of extension. The radial area of the first reinforcement carcass is mounted between the supporting flange and the annular lamina(e). A second reinforcement carcass, likewise consisting of at least one reinforcement layer, partially or completely holds the outside of the fitting, especially by way of fastening means. A filler material produced from an elastomer material, in the area of the fitting, fills the space between the first and the second reinforcement carcass. The coupling is integrated into the hose in such a manner that all hose components associated with the coupling give a material-fit hose/coupling system. The invention also relates to a method for producing a hose of the above-described type.
