ABSTRACT:
A woven hollow 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, in which one tape edge is formed as a knitted edge and the weft density is much less than that found in normal woven textile tapes, each weft being spaced apart from the adjacent wefts. The tape is produced by a weft insertion that takes place in a manner similar to that of a shuttleless ribbon loom, especially a needle ribbon loom, preferably using freshly spun hollow fibers. The resultant tape may have hollow fibers along both edges and may be used to form the appropriate products either with or without the weft threads which are easily removed as a result of the tape structure.
