Abstract
A knotting mechanism for use on open-end spinning machines for performing a knotting process on yarn produced on machines. The knotting mechanism is mounted so that it can be moved longitudinally along the spinning machine and transversely to the spinning machine to a knotting position. A switch-on mechanism is activated responsive to the knotting mechanism being moved transversely to the spinning machine to a knotting position. A driving mechanism is provided for initiating the knotting process on the yarn upon being activated. A release mechanism is operably connected to the driving mechanism for activating the driving mechanism responsive to the switch-on mechanism being activated. A timing device de-activates the driving mechanism after a predetermined period of time sufficient to carry out the knotting process and prevents the driving mechanism from initiating another knotting process without the switch-on mechanism being further de-activated and re-activated. Both electro-mechanical and mechanical mechanisms are provided for insuring that only a single knotting process is performed while the knotting mechanism is in the region of the yarn that is to be knotted.
