Elongated, large diameter, helically wound, hollow fiber bundles which are stable, do not require “dead-end tubesheets”to keep the bundle ends from slipping and exhibit only slight “dog-boning”can be formed by controlling the winding parameters so that the bundle consists of successively shorter or longer “formations”of successively longer strata, each stratum consisting of from about one to a plurality of coverages (of the underlying core or bundle surface).

A method of forming a stable, self-anchored, generally cylindrical hollow fiber bundle having generally dome-shaped ends, by back and forth helical winding of one or more hollow fibers on a rotating core; said method comprising controlling the winding so that said bundle consists of a plurality of successively shorter formations, each formation being of successively longer strata, each stratum consisting of from about one to a plurality of coverages, and each formation having somewhat enlarged end portions, thereby ensuring that the enlarged end-portions of each formation are axially located with respect to the corresponding such end-portions in adjacent formations so that the bundle itself does not have a substantially dog-boned shape and said bundle ends are generally dome-shaped.
