ABSTRACT:
Manufacture of bundles of at least 1000 semi-permeable hollow fibres for use in filters such as, e.g., blood, plasma and dialysate filters, and in artificial kidneys. One or more hollow filaments are wound onto a reel until the formed package contains the number of filaments required for bundle formation. After which the package is cut into fibre bundles of the desired length. The package is held in one place of the reel and a free end is introduced into a sleeve having a length which is a number of times that of the length of the fibre bundle in the final filter. The sleeve is cut into fibre bundles of the desired length.
