1. A method of making an apparatus for exchanging substances between first and second mediums, the method comprising the steps of:
winding a mat of semipermeable fiber tubes on an outer winding core that has an outer core opening for inflow or outflow of the first medium,
fitting the outer winding core with the mat in an axially extending housing for flow of the first medium into or out of a port of the axially extending housing surrounding the outer winding core and having axially opposite ends,
axially displacing the outer winding core relative to the fiber tubes around the outer winding core and relative to the housing to adjust an axial spacing between the outer winding core opening and the port to a desired value from several possible values,
bonding with a sealing adhesive at the axial ends of the housing the tubes to the outer winding core, to one another, and to the housing, and thereby forming a chamber containing the tubes and through which the first medium can flow between the outer winding core opening and the port and for flow of the second medium through the tubes between the axial ends of the housing for substance exchange between the first and second mediums,
sealing an end of the housing close to the port such that the fiber tubes are sealed with adhesive in an area between one of the axial ends of the housing and the port, and
sealing and bonding the fiber tubes to another end of the housing close to the outer core opening in an area between an axial end face of the housing and the outer core opening axially up to the outer core opening.
