    Abstract: Apparatus for the manufacture of curved braids comprises a braiding machine provided with pull-out and take-up apparatuses. The pull-out apparatus includes a forming ring and a pair of driven frustoconical pull rolls having an adjustable nip. The members to be braided are formed into a curved flattened tube as they are drawn through the forming ring by and through the nip of the pull rolls. The curved braid as it exits the nip of the pull rolls is guided onto a take-up bobbin. A conventional tubular braiding machine may be used. Such curved braids are suitable for use in the manufacture of fibrous preforms for the manufacture of friction discs.
