One end of said shaft 40 auxiliary shaft along the line 2-2 of FIG. 1; is provided with a suction opening to be closed by a FIGS. 3—8 are diagrams showing the blowing device valve. The opposite end of said shaft cooperates with a with the shaft according to FIG. 1 and showing the blowing device for introducing the length of the thread suction steps for presenting a weft; as weft from the shaft into the shed. FIG. 9 is a perspective view of a loom provide-d with Such a device is described in United States Patent a device for storing a length of weft thread and intro 3,024,814. In that device the open mouth of the shaft ducing it into the shed; and is positioned at a distance from the blowing device. FIG. 10 is a fragmentary side elevation of the device Further a shaft having a blowing device integral with it shown in FIG. 1. is described in United States Patent 3,137,322. Description of the preferred embodiment As the interior of the shaft described in the latter patent 50 has the shape of a ?at cleft, this cleft is provided with A device according to the invention, which device widened parts at each side, which widened parts are is adapted to be used in a loom, comprises a jet nozzle' adapted as a mixing-tube and to receive the blowing for weft insertion by jet action, known per se. The jet nozzles. In the mouth of the shaft two blowing devices nozzle comprises a block In having a recess into which are thus arranged, which blowing devices will be alter nately operative. is set a nipple 2a. The inner end of the nipple 2a is smaller than the recess in the block 1a, so as to leave Summary of the invention an intervening annular space which constitutes an annu lar nozzle 1 for air under pressure, which nozzle is The object of the invention is to improve such a device situated around a supply channel 2 which extends cen for taking up a loop in a thread by suction action and trally through the nipple 20. When air under pressure to blow this thread from the shaft in which it was tem porarily stored into the shed of a loom. is supplied to the space between the block 1a and the nipple 2a, so as to discharge air under pressure through According to this invention this is attained in that the annular nozzle 1, the resulting aspiration applies the shaft is provided with a separate opening for sucking suction to the supply channel 2 for drawing in second in the thread, which opening is positioned between the ary air and for supplying the thread. A mixing tube blowing device and the suction opening which is to be closed by a valve. 3 is positioned in front of the annular nozzle 1 and Now the measured length of the thread does not pass the channel 2. The channel 2 merges into a widened the blowing device. part 4 which extends through a block 4a that ?ts around the outer end of the nipple 2a and is situated in front Further the shaft can be rigidly fastened and need 70 of the mouth of the shaft 5.
