摘要： A method for closing one side of a hollow fiber membrane including a lumen and a wall radially enveloping the lumen, wherein the wall includes an inner textile layer, wherein a portion of a low viscosity resin flows at least partially through a face of the hollow fiber membrane into an end portion of the hollow fiber membrane and closes the end portion with an outer free surface and is being cured by UV light. In order to reduce a propensity for blocking between the end portions of the hollow fiber membranes it is proposed that that the portion is fed in its entirety by positive pressure through the face into the end portion and cured after a time period of 5 seconds at the most, and that the portion is arranged exclusively within the hollow fiber membrane after curing.
