摘要：
A bundle of hollow fibers of uniform diameter, particularly for use in dialysis is formed of a plurality of parallel hollow fibres at least a part of which, prior to the formation of the bundle, is permanently undulated by means of interleaved undulating elements moving opposite the feeding direction of freshly extruded fibres. The undulating elements are in the form of cylindrical rods having a substantially larger diameter than the outer diameter of the fibres so that the wavelength and amplitude of the resulting undulations are substantially larger than the outer diameter of the fibres.
