ABSTRACT:
Capillary fiber bundles of semipermeable membrane material may be used by winding the fibers onto a reel member to form an annular assembly of the fibers, and thereafter cutting the annular assembly into separate bundles. In accordance with this invention, the capillary tubing is fed to the reel through guide slot means elongated in a direction generally parallel to the axis of rotation of the reel. The tension on the capillary tubing is sufficiently low to allow the capillary tubing to move about while winding in the guide slot means in generally random manner. Accordingly, the bundles comprise strands in generally non-parallel, crossing arrangement with adjacent strands. Individual bundles may be wrapped in a special flexible sheet, and cut at their ends for improved quality.
