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.

Abstract: An apparatus for continuously coating individual fibers of a fiber bundle with resin, which comprises a first concave support surface for grouping the fibers of the bundle substantially at a single grouping point and a second, convex, support surface at least partially described by an arc rotated about its horizontal axis, having a maximum radius R, which at least approximately satisfies the relationship expressed in the following formula: wherein r designates the radius of the arc at distance x from the plane of symmetry, passing through fiber grouping point (P): ##EQU1## and wherein L designates the length of a tangent to the second support surface which passes through grouping point (P), in the plane of symmetry, and .phi. designates the radian angle formed between the tangent and the vertical line.
