    摘要： A method of producing at least one yarn formed by spinning at least two individual fibers, comprising the following steps: providing at least two individual fibers, to be spun to form the at least one yarn to be produced, feeding the at least two provided fibers to a spinning device comprising at least one spindle element or bobbin element via a guide device comprising a plurality of, in particular cylinder-like or cylindrical, guide elements, spinning the fed fibers in the spinning device, forming the at least one yarn to be produced, wherein the at least two individual fibers are fed to the spinning device via at least two separate, in particular cylinder-like or cylindrical, guide elements that are arranged such that they are spatially separated from one another in at least one spatial direction.

    摘要： A method for producing a twist ply yarn having two strands with the same twist direction and twist intensity includes the steps of false twisting each of two strands to produce a twist in a first direction upstream of the false twister and in the opposite direction downstream of the false twister, removing the twist in the strands downstream from the false twister and twisting the two strands together.

    摘要： In a spinning operation in which two strands are fed from separate nip positions and are twisted together into a single ply at a convergence point, twist is incorporated into the single strands by cyclically varying the path lengths of the strands between the nip positions and the convergence point. Preferential spiralling of one strand about the other is prevented by ensuring that the ratio of feed of the strands to the convergence point are substantially equal.

    摘要翻译： 在纺纱操作中，其中两股从单独的辊隙位置进给并且在会聚点处被扭绞在一起成为单个帘布层，通过循环地改变轧辊位置和收敛之间的股线的路径长度，将捻合结合到单个股中 点。 通过确保股线与收敛点的供给比例基本上相等来防止一条股线绕着另一股线的优先螺旋化。
