One or more take-up rollers include a plurality of sectors releasably fastened on the outer surface of the take-up roller. Each sector extends over a fraction of the circumference of the take-up roller and over all or part of the axial width of the take-up roller. Each sector also presents at least one thickness that is determined in such a manner as to modify locally the thickness of the profile in relief of the outer surface of the take-up roller. ## Claims ### Claim 1 An installation for fabricating a fiber texture in the form of a strip presenting a profile that varies at least in cross-section, the installation comprising a loom one or more take-up rollers, and a storage mandrel each take-up roller and the storage mandrel presenting a radius that varies across its axial width so as to define an outer surface having a profile in relief; wherein at least one take-up roller includes a plurality of sectors releasably fastened on the outer surface of said take-up roller, each sector extending over a fraction of the circumference of the take-up roller and over all or part of the axial width of the take-up roller each sector also presenting at least one thickness that is determined in such a manner as to modify locally the thickness of the profile in relief of the outer surface of the take-up roller. ### Claim 2 (depends on 1) The installation according to claim 1, wherein each sector presents a thickness that varies in the axial direction. ### Claim 3 (depends on 1) The installation according to claim 1, wherein each sector presents an inner surface having a shape corresponding to the portion of the outer surface of profile in relief of the take-up roller on which said sector is fastened. ### Claim 4 (depends on 1) The installation according to claim 1, wherein each sector includes a layer of grip material on its outer surface. ### Claim 5 (depends on 1) The installation according to claim 1, wherein at least one sector of the plurality of sectors has an edge that is chamfered so as to avoid putting the preform into contact with a sharp edge on a sector that has been added to the take-up roller. ### Claim 6 (depends on 1) The installation according to claims 1, comprising a first take-up roller placed in the proximity of the outlet from the loom, and at least one second take-up roller placed between the first take-up roller and the storage mandrel the second take-up roller including a plurality of sectors releasably fastened on the outer surface of said second take-up roller, each sector extending over a fraction of the circumference of the second take-up roller and over all or part of the axial width of said second take-up roller each sector also presenting a thickness that is determined in such a manner as to modify locally the thickness of the profile in relief of the outer surface of the take-up roller. ### Claim 7 A method of fabricating a fiber structure in the form of a strip presenting a varying profile in cross-section by three-dimensional or multilayer weaving between a plurality of layers of warp yarns interlinked by weft yarns the warp yarns being driven at the outlet from the loom by one or more take-up rollers the fiber texture being wound onto a storage mandrel placed downstream from the take-up rollers, each take-up roller and the storage mandrel presenting across its axial width a radius that varies so as to define an outer surface having a profile in relief; wherein, during weaving, the method comprises adding a plurality of sectors on the outer surface of at least one take-up roller each sector extending over a fraction of the circumference of the take-up roller and over all or part of the axial width of said take-up roller each sector also presenting at least one thickness that is determined in such a manner as to modify locally the thickness of the profile in relief of the outer surface of the take-up roller. ### Claim 8 (depends on 7) The method according to claim 7, wherein each sector extends over a fraction of the circumference of the take-up roller which fraction is determined as a function of the circumferential fraction of contact between the fiber texture and the outer surface of said take-up roller. ### Claim 9 (depends on 7) The method according to claim 7, wherein each sector presents a thickness that varies in the axial direction. ### Claim 10 (depends on 7) The method according to claim 7, wherein each sector presents an outer surface having a shape corresponding to the portion of the outer surface of profile in relief of the take-up roller on which said sector is fastened.
