发明名称 Device for continuously producing reinforced stabilizable profiled bodies by a mandrel and a support
摘要 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.
