摘要
Positioning the jet to detect the yarn end, on a wound cops at a spinning machine, takes the current spinning data from the spinner (1) and the wound dia. (D) of the cops (7) at the conical start cops section for a current time point. The resulting value is used to position the yarn detection jet (3) according to the wound dia. (D) at the given time. ADVANTAGE - The method improves the working function of the yarn preparation unit, and increases the yarn detection success rate. Pref. the actual spinning data from the spinner (1), together with the cops (7) dia. (D) at the conical start section at the actual time is calculated into a value to be stored, which is used to move the yarn detection jet (3) according to the cops (7) wound dia. (D). A number of function values can be stored in the memory, for access on a change of spinning machine data, for the optimum jet (3) positioning and automatic adjustment within a value threshold range.
