ABSTRACT:
The invention permits the ends of a hollow fiber bundle to be dried, without drying the intermediate portions of the bundles, thereby enabling the bundle to be potted. The apparatus includes at least one drying member having two couplings for coupling a source of forced hot air to respective ends of a sheath designed to contain a bundle of hollow fibers. At each of its ends, the sheath includes at least one axial opening through which the hot air penetrates into the sheath, and at least one lateral opening through which the hot air leaves the sheath after passing over the ends of the fibers. The inlet air flow rate to the sheath and the dimensions of the openings are selected so that all of the air entering each of the ends of the sheath leaves via a corresponding lateral opening.
