Abstract
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.
