Abstract: A method of forming a metal matrix composite (MMC). The method comprises providing a fiber (26) comprising a ceramic material coated with a metal, providing a winding head (12) having a plurality of circumferentially spaced radially extending alternate first and second finger members (18, 20), the finger members each defining a winding surface (22, 24), the winding surface of each first finger member facing a first axial direction, and the winding surface of each second finger member facing a generally opposite axial direction, wherein adjacent winding surfaces (22, 24) of the first and second finger members (18, 20) are spaced in a circumferential direction, and define an axial spacing less than the diameter of the fiber (26), and winding the fiber around the winding head (12) between the winding surfaces (22, 24) of the first and second finger members (18, 20).

Abstract: In the crimping of textile fibers, opposed rolls are rotated to force-feed the fibers through a nip defined by the rolls and into a stuffer box. A pair of cheek plates are pressed against the ends of the opposed rolls such that a front surface of each cheek plate engages ends of both rolls adjacent the nip to retain the fibers against lateral displacement from the nip. Atomized lubricating liquid is sprayed toward an inlet of the nip and against portions of the ends of the rolls approaching the nip, and against backsides of the cheek plates.
