ABSTRACT:
In the production of a thread-reinforced hose from polymeric material, the still formable material, a mold core, and the reinforcing thread or threads are fed continuously into a shear head and united. This takes place while utilizing the rotary movement of the shear mandrel contained in the shear head such that each thread used is passed axially through the shear mandrel and is wound around the mold core after emerging from an opening at the end. The embedding of the thread into the material and its winding about the mold core take place simultaneously. After the finished hose emerges from the nozzle of the shear head the material solidifies and the mold core is removed.
