| | For asymmetric ply yarns or multi-ply constructions cross-wound packages are still produced in a two-level twisting process according to the two-for-one principle. On the Allma TCS with assembly winding unit, the individual threads are twisted separately and wound onto a doubling bobbin. Here, up to 6 individual threads can be assembled and wound onto the take-up package. The cylindrical cross-wound package is then fed to a Allma TCS spindle and final-twisted. |
