Abstract (en)
[origin: WO2019211181A1] Present invention discloses a method of melt-spinning and winding synthet- ic yarns, wherein a polymer melt is conveyed through a spin pump and fed to a plurality of spinnerets which extrude the polymer melt into a plurality of yarns respectively, wherein the yarns are wound to a plurality of bobbins by a winding device and wherein the spinnerets are regularly maintained by wiping a spinneret nozzle plate, wherein, the maintenance of at least one of the spinnerets is initiated by manual pressing a wiping button which is con- nected to a machine control unit and the machine control unit generates a control command which is transmitted to a wiping robot. By replacing op- erators with a wiping robot automatic spinneret nozzle plate wiping is achieved. By integration of wiping robot with spinning control system the operator could define the wiping robot to start wiping action.
