MANUFACTURE OF FLEXIBLE TUBULAR BODIES

摘要

The invention refers to a method and a device for the manufacture of flexible tubular bodies in which one or more profiled strands are deformed spirally in a permanent manner before proceeding to winding it or them spirally in order to form a cylindrical carcass, by making the profiled strand pass over two pulleys in succession. The profiled strand is wound on the flat round each of the pulleys, the axes of the two pulleys being angularly offset so as to cause a permanent twist in the length of profiled strand situated between the said two pulleys.
