Abstract
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.
