  • Patent number: 4967803
    Abstract: Method of preparing a weft and its removal from an open shed in jet weaving machines automates the preparatory operation of weft upon finding a weaving fault. This is achieved by performing both the preparation and the withdrawal of the weft in the course of the first quadrant of the jet weaving machine revolution. The method includes the step of supplying a further unseparated weft length, forming a loop between the unseparated weft length in the open shed while the loop elongates due to the action of an inserting medium until the loop face emerges from the shed on the shed outlet side and removing the weft from the shed by a weft withdrawing device.
