Abstract
A method and device for producing woven hollow fiber tape, for use in exchange devices such as blood oxygenators and heat exchangers, having weft threads and hollow fibers as warp threads, formed as a double weft tape. The device feeding a plurality of parallel hollow fibers as warp threads in a first direction, dividing alternating adjacent hollow fibers to create two sets of hollow fibers, separating one set of the hollow fibers from the second set to create a gap therebetween, inserting a double weft thread into the gap and knitting the double weft thread at a side of the plurality of parallel hollow fibers away from that side where the double weft thread is initially inserted. The hollow fibers are separated into the two sets by a reciprocating shedding device thereby creating the gap for insertion of the weft threads.
