Zusammenfassung:Procedure for the continuous thermoforming of a double tubular fabric for the production of multitubular sheaths, depending on a technique of fixed mandrels, in which the fabric consists of a warp of continuous high tenacity multifilament yarns of polyester that are thermically non-shrinking and with a high torsion, and that run on revolving rolling-bearings placed inside the fabrics tubes, against free blocking rollers placed externally. The device for the realization of such procedure involves: a feeding station (A), a station for the blocking of the mandrels (B), means for the advancement of the fabric (C), a thermoforming furnace (D) and eventually a cooling station (E) and a cutting station (F), in which the blocking station (B) is provided with two free rollers placed on the two sides of the fabric where they contrast the roller-bearings arranged on the mandrels.
