Method, consisting of a) a method for producing a reinforced flexible hose line and b) a subsequent use of the hose line produced by said method, wherein a) in the method for producing the hose line - a polymeric basic hose is extruded, - a pre-heated adhesive layer is applied to the basic hose, - a thread-type reinforcing layer is applied, preferably wound onto the still hot and therefore deformable adhesive layer and the reinforcing threads in this case sink into the adhesive layer due to its deformability, such that the reinforcing layers for a hybrid layer together with the adhesive layer, - wherein the reinforcing threads completely immerse in the adhesive layer when forming the hybrid layer, - wherein thereafter a polymeric outer layer is extruded onto the hybrid layer, - wherein PVC is used as the polymeric material for the basic hose and the outer layer, - wherein the hoseline produced this way merely consists of basic hose, hybrid layer and outer layer, and wherein b) after being finished, the hose line is used for transporting cleaning water of temperatures of 40 to 80°C and pressures of 30 to 70 bar in slaughterhouses or butcheries. a) a method for producing a reinforced flexible hose line and b) a subsequent use of the hose line produced by said method, wherein a) in the method for producing the hose line - a polymeric basic hose is extruded, - a pre-heated adhesive layer is applied to the basic hose, - a thread-type reinforcing layer is applied, preferably wound onto the still hot and therefore deformable adhesive layer and the reinforcing threads in this case sink into the adhesive layer due to its deformability, such that the reinforcing layers for a hybrid layer together with the adhesive layer, - wherein the reinforcing threads completely immerse in the adhesive layer when forming the hybrid layer, - wherein thereafter a polymeric outer layer is extruded onto the hybrid layer, - wherein PVC is used as the polymeric material for the basic hose and the outer layer, - wherein the hoseline produced this way merely consists of basic hose, hybrid layer and outer layer, and wherein b) after being finished, the hose line is used for transporting cleaning water of temperatures of 40 to 80°C and pressures of 30 to 70 bar in slaughterhouses or butcheries. wherein a) in the method for producing the hose line - a polymeric basic hose is extruded, - a pre-heated adhesive layer is applied to the basic hose, - a thread-type reinforcing layer is applied, preferably wound onto the still hot and therefore deformable adhesive layer and the reinforcing threads in this case sink into the adhesive layer due to its deformability, such that the reinforcing layers for a hybrid layer together with the adhesive layer, - wherein the reinforcing threads completely immerse in the adhesive layer when forming the hybrid layer, - wherein thereafter a polymeric outer layer is extruded onto the hybrid layer, - wherein PVC is used as the polymeric material for the basic hose and the outer layer, - wherein the hoseline produced this way merely consists of basic hose, hybrid layer and outer layer, and - a polymeric basic hose is extruded, - a pre-heated adhesive layer is applied to the basic hose, - a thread-type reinforcing layer is applied, preferably wound onto the still hot and therefore deformable adhesive layer and the reinforcing threads in this case sink into the adhesive layer due to its deformability, such that the reinforcing layers for a hybrid layer together with the adhesive layer, - wherein the reinforcing threads completely immerse in the adhesive layer when forming the hybrid layer, - wherein thereafter a polymeric outer layer is extruded onto the hybrid layer, - wherein PVC is used as the polymeric material for the basic hose and the outer layer, - wherein the hoseline produced this way merely consists of basic hose, hybrid layer and outer layer, wherein b) after being finished, the hose line is used for transporting cleaning water of temperatures of 40 to 80°C and pressures of 30 to 70 bar in slaughterhouses or butcheries.
