Process for forming flexible tubular bodies and device for carrying out said process. |
摘要 |
<p>The process according to the present invention for forming flexible tubular bodies (12) obtained by the laying-up of a plurality of metallic shaped members (5), permanently deformed according to helicoids, provides to give the helical configuration to the single shaped members through the following two steps.
<??>Each shaped member (5) is firstly permanently deformed around their own longitudinal axis by torsional stresses. Subsequently, each shaped member (5) is permanently deformed through a bending with respect to a plane parallel to the greater faces of the shaped member (5) itself. The present invention comprises also a device for carrying into effect said process. </p> |
