ABSTRACT:
A method for repairing a weft thread on a weaving machine, in particular for repairing thread breaks between a yarn supply package and an accumulator, includes the step of providing at least two yarn supply packages, a second package automatically replacing the one in use when the one in use becomes empty. Additional steps include using a thread clip to hold a thread end of the second supply package, monitoring the weft thread for breaks between the supply package in use and the accumulator, and when a thread break is detected, gripping the thread end of the second supply package and joining it to the broken weft section which is connected to the accumulator. An apparatus is provided which includes means for carrying out each of the above-described steps.
