Patent ID: 10781543

Abstract:
The invention relates to guide tooling (22) for a circular needling table for needling a textile structure made from a helical fiber sheet, the tooling comprising an inner guide rail (24) of circularly arcuate shape, and an outer guide rail (26) of circularly arcuate shape arranged coaxially around the inner guide rail and connected thereto by radial reinforcement (28), the outer and inner guide rails defining between them a passage for guiding the helical fiber sheet under a needling head, the outer guide rail being made up of two outer guide rail angular sectors (26a, 26b) that are connected to each other by an outer actuator (28), the outer actuator being suitable for moving the adjacent free ends (26a-1, 26b-1) of the outer guide rail angular sectors apart from each other so as to expand the outer guide rail.
