ABSTRACT:
A hollow filament module comprising an annular package of hollow filaments having a longitudinal axis, an axially extending flow channel of a hardened mass, and an outer mantle likewise of a hardened mass coaxial with said flow channel and radially outwardly arranged from the latter, the hollow filaments forming the package being curved and of substantially equal lengths and extending in substantially radial direction in planes forming with the aforementioned axis an angle of substantially 90.degree., the filaments in adjacent planes crossing each other and engaging each other at crossing points, each of the hollow filaments having two open ends embedded in the hardened mass so that fluid may flow through the respective filament, the open ends of some of the filaments being arranged to at least communicate with the axially extending flow channel, and the open ends of some of the filaments being arranged to at least communicate with the peripheral surface of the outer mantle; and a method of forming the hollow filament module as well as an apparatus for forming the annular package of hollow filaments.
