PERFECCIONAMIENTOS EN LAS DISPOSICIONES PARA FABRICAR CUER- POS HUECOS TUBULARES

摘要

The invention relates to a method and apparatus of manufacture of fiber reinforced tubular bodies which comprise in combination at least on cover layer and at least one core layer; said layers being wound upon a winding mandrel the shape of which corresponds to the desired shape of the hollow body. The method includes the use of a control unit which comprises a compression tunnel adapted to reduce the thickness of the core and cover layers thereby applying compressional and tensile forces simultaneously to the layers resulting in a more homogeous and therefore stronger bond between the layers.
