摘要: 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.

摘要: Weft inserting device adapted to be fixed on the frame of a jet loom or to the beat-up motion thereof. The device has two mixing tubes which are united at the location of their outlet ends so as to form a single central outlet portion terminating in a single outlet opening, the outlet opening being followed by a directing portion with an open passage through. In the weft inserting device of the invention, the central outlet portion of the weft inserting device, starting from the discharge ends of the mixing tubes, is divided by means of a baffle disposed in a first plane which is perpendicular to a second plane containing the longitudinal axes of the mixing tubes, the baffle extending from the discharge point of the mixing tubes throughout at least a portion of the length of the central outlet portion. The longitudinal axis of the baffle lies in a plane which contains the axis of the directing portion of a weft inserting device.
