Abstract
In a method for manufacturing hollow fiber piles, at least one hollow fiber strand is wound spirally onto a rotating drum having a polygonal cross section to form superimposed hollow fiber layers thereon, forming a hollow fiber roll on the drum. Once the desired number of hollow fiber layers has been formed on the rotating drum, segments of a desired shape are separated from substantially planar regions of the hollow fiber roll. Simultaneously, or immediately following this separation, adjacent end regions of the hollow fibers are connected with one another at least spotwise.
