    摘要: Logic signals corresponding to a detected thread break and/or thread loop in a package being wound on a bobbin are evaluated within a logic circuit to communicate the quality of a thread package. The logic signals can be processed in various ways.In one embodiment, discrimination is made of repeated logic signals produced by a single thread break.In another embodiment, the total number of logic signals are counted.Blocking arrangements can be provided to block logic signals caused by the same thread break or thread loop.

    摘要: The monitor is spaced a small distance from the curved path of the travelling thread to sense defects in the thread. In one embodiment, the monitoring means is spaced from the winding surface of a chuck to sense broken threads or an accurate build-up of the thread package. The monitoring means includes a detector head with a charge collector rod for sensing changes in electrical potential of the rod due to contact with a travelling thread part. The monitoring means can be moved away from the chuck to maintain a constant distance from the thread package being wound on a bobbin tube on the chuck.
