METHOD FOR MANUFACTURING HOLLOW FIBRE PILES

摘要

A method for the manufacture of hollow fibre piles, in which at least one hollow fibre is wound spirally onto a rotating drum having a polygonal cross section, superimposed hollow fibre layers are formed and, once the desired number of hollow fibre layers has been obtained, segments of a desired shape are separated from the substantially planar regions of the hollow fibre roll formed in this manner and simultaneously or immediately following said separation, adjacent end regions of the hollow fibres are connected with one another at least spotwise.
