Title:
FORMATION OF HOLLOW FILAMENT MEMBRANE BUNDLE
Document Type and Number:
Japanese Patent JPH0623241
Kind Code:
A
Abstract:

PURPOSE: To minimize the pressure drop of inner and outer sides by assembling many hollow filament membranes to one unit often called as a bundle, then assembling these membranes together with a suitable conduit to a module in order to put the hollow filament membrane into practicability.

CONSTITUTION: Continuous lengths of filaments are laid down on a core and are, on the other hand, rotated first in a 'forward' sense and the filament lay-down position is moved from the first end to the second of the core and is thereafter moved in a 'reverse' sense, while the hollow filament membrane is moved from the second end to the first end. Reversing of the direction of core rotation and filament end-to-end traversal are repeated with the reversing controlled in such a manner that the path of the filament returning from either end to the other is displaced incrementally from that of the filament portion laid down in the immediately preceding traversal.
