Abstract
The present disclosure relates to a process for producing a filtration and/or diffusion device. e.g., a capillary dialyzer or an ultrafilter, and to devices used in the process.
Claims14
A process for producing a filtration and/or diffusion device comprising a bundle of hollow fiber membranes in a tubular housing, the process comprising melting a first end and a second end of a bundle of hollow fiber membranes having at least one slanting end face, thereby sealing the mouths of the individual hollow fiber membranes within the bundle, and producing a bundle of defined length and having parallel end faces which are perpendicular to the longitudinal axis of the bundle, and subsequently transferring the bundle into a tubular housing of a filtration and/or diffusion device.
A bundle reshaping device comprising two conveyor belts mounted on vertical drive rollers, wherein each conveyor belt forms a closed loop driven by a plurality of vertical drive rollers, and wherein the two conveyor belts are spaced apart from each other, a surface of each of the conveyor belts facing a surface of the respective other conveyor belt, the two conveyor belts together defining a first section and a second section of the bundle reshaping device, and wherein each conveyor belt comprises at least one heating unit within the first section and at least one cooling unit within the second section.
