Abstract (en)

[origin: EP2141105A1] The invention relates to a splicing head that can improve the strength of a pieced portion. A plurality of two-ply yarns (70, 71) that are to be pieced are untwisted by injecting a compressed fluid via an untwisting-nozzle hole (32) Subsequently, an impact is imparted to the plurality of two-ply yarns (70, 71) thus untwisted by injecting a compressed fluid via a piecing-nozzle hole (33). When the plurality of two-ply yarns (70, 71) are untwisted respectively, and then an impact is imparted to the plurality of two-ply yarns (70, 71) from a compressed fluid in this manner, the plurality of two-ply yarns (70, 71) themselves are complexly intertwined into each other, and fibers projecting from the plurality of two-ply yarns (70, 71) are complexly intertwined into each other. Accordingly, the strength of a pieced portion in a yarn obtained by piecing can be improved.
