Method and apparatus for simultaneous production of plural hollow fiber devices by winding

摘要

A process and apparatus are disclosed for the simultaneous preparation of several hollow fiber devices especially useful for fluid fractionation operations, wherein at least one hollow fiber is wound around means, at least three in number, located in different planes thereby obtaining with this fiber an envelope having a polygonal section, which can be cut in at least two places as it is formed, so as to obtain at least two distinct groups of hollow fiber lengths. Various specific embodiments are described.
