ABSTRACT:
There is disclosed herein an apparatus and method for preparing a continuous, hollow, and semipermeable filament for use in a dialyzer which includes a plurality of substantially-equal-length open-ended fibers.
The apparatus includes a body having a supply spool of filament and a take-up reel having at least two radially-spaced support means about which the filament is wound. Drive means rotate the take-up reel and a filament guide is provided for laterally positioning the filament on the support member so as to prevent close packing of the filament windings. The take-up reel includes a winding plate for carrying the filament support means and hub-and-locking means for releasably mounting the winding plate on the machine.
The method includes winding the filament from the spool onto the take-up reel; grasping each of the sections of filament between the support means; and cutting the filament adjacent the support means so as to form a plurality of bundles of open-ended fibers for use in a hollow fiber dialyzer.
