Abstract
A method for continuously coating individual fibers of a fiber bundle with resin. The individual fibers are grouped at a single grouping pint defined by a first concave supporting surface. The fibers are directed through a resin bath while spreading the fibers apart on a convex surface in a regularly spaced arrangement to form a continuous coating of resin along at least a portion of the fibers. The convex surface is at least partially described by an arc rotated about a horizontal axis, and comprises at least a portion of a surface of maximum radius R which is symmetrical relative to a vertical plane of symmetry passing through the fiber grouping point. The convex surface is substantially defined by the equation ##EQU1## wherein: r=the radius of the arc at a distance x from the plane of symmetry passing through the grouping point;
