  • Doffing control system in automatic winder
    Patent number: 4512526
    Abstract: The present invention relates to a doffing control system in an automatic winder. When a signal for turning off a drum motor for stopping a traversing drum is put out to stop rotation of the drum due to a full-winding signal and then the yarn is wound up on a package by an inertia rotation of the drum, the detecting action of the slub catcher is maintained even after emission of the full-winding signal until the yarn speed is reduced to a level corresponding to the critical limit of sensing yarn breakage by the slub catcher.
