ABSTRACT:
The present invention provides a method of controlling yarn joining operation on the basis of signals provided by a slub catcher which generates a yarn breakage signal upon the detection of a slub during winding a yarn being supplied from a yarn supply bobbin on a take-up package. A change of a yarn supply bobbin for a new yarn supply bobbin and a yarn joining operation are conducted upon detection of the slub catcher whether a yarn breakage is occurred and/or detection of the yarn absence under what conditions.
