Method for setting up yarn body at spinning or twisting machine, involves providing conical cone layers at middle section of yarn body, where yarn layers are designed in middle section

摘要

The method involves providing conical cone layers at a middle section of a yarn body (66). The corresponding double stroke height of the cone layers is larger over a subarea of the middle section as the double stroke height of the last yarn layer (64) in a cone tip. The yarn layers, with a coning angle (W4,WS4), are designed in the middle section. An independent claim is included for a yarn coil produced at a spinning or twisting machine.
