A device for continuously producing reinforced stabilizable profiled section bodies, with the device including a mandrel and a drive for rotationally driving the mandrel around the longitudinal axis thereof. The mandrel maintains at least one support of a profile section helically wound on the mandrel. A reinforcement impregnated with stabilizable material is wound around the mandrel and the at least one support. A stabilization arrangement is disposed on at least one portion of a length of the mandrel, and the reinforced material, having undergone stabilization, is separated from the mandrel. The support is wound onto a first extremity of the mandrel and separated from the mandrel at a second extremity. The first extremity of the mandrel includes a first elevated zone or calibration bearing surface on which the support is to be wound, with the bearing surface having a sufficient length to drive the support, through a capstan effect, while not impeding a progression of the support on the mandrel.
Device for continuously producing profiled section bodies of a reinforced stabilizable material, the device comprising a mandrel means, means for rotationally driving said mandrel means around a longitudinal axis thereof, at least one profiled sectional support means wound helically onto said mandrel means, means for moving to make said at least one profiled sectional support means longitudinally on said mandrel means, means for winding reinforcement elements impregnated with stabilizable material around the mandrel means and onto said at least one profiled sectional support means means disposed along at least one part of a length of the mandrel means for stabilizing the stabilizable material, means for separating the reinforced material having undergone stabilization from the mandrel means, said at least one profiled sectional support means being wound at a first extremity of the mandrel means and separated from the mandrel means at a second extremity thereof, and wherein a first elevated zone is provided at the first extremity of said mandrel means upon which said at least one profiled sectional support means is wound, said first zone having a length sufficient to enable a driving of the at least one profiled support means through a capstan effect relative to the mandrel means without impeding a forward movement of the at least one profiled sectional support means on said mandrel means.
