Method and a machine for making hollow reinforcing members

摘要

A method and a machine for making a hollow fiber reinforcing member using a mandrel. A plurality of flexible rods are distributed around the periphery of the mandrel. Each rod is provided at one extremity with a respective curved end so that at least the extremities with bent ends are pressed against the mandrel, with their bent ends projecting outwards from the mandrel. At least one continuous strand of filaments is interlaced around the bent ends of the rods. As the strand of filaments is interlaced around the bent ends, the rods are displaced along the mandrel to disengage the already-interlaced strand of filaments from the bent ends of the rods such that a tracery of filaments including the rods and bearing against the mandrel is formed progressively.
