Abstract
A transfer tail forming apparatus for weft feeders fed to a weaving machine, wherein a tail end of a feeder now in use and a leading end of a preliminary feeder are connected together using a knotter. The tail end and the leading end are automatically positioned and held in a predetermined position by a positioning apparatus, and the yarn ends are connected together by the knotter to form a transfer tail. Further, by the provision of a stand-by apparatus the transfer tail is held in a predetermined posture, and when the whole quantity of the weft on the feeder now in use has been consumed, the leading end of the preliminary feeder can be introduced into the weaving machine in a continuous manner. Moreover, when the supply of weft from the feeder now in use is discontinued, the introduction of the leading end from the preliminary feeder is made possible by the stand-by apparatus. Additionally, by combining with the apparatus a conveyance cassette having a yarn end fixing member at the time of conveyance of a feeder to a feeder stand, the leading end and tail end of the feeder can be held automatically for the above positioning apparatus.
