Definitions
- FIG. 1A is a longitudinal view of one type of device for adjusting the distance between the ejecting device of FIG. I and the weft'yam cutter;
- FIG. 2 is a perspective view of the apparatus shown in FIG. 1 and disposed at one side of the loom;
- the yarn carrier in FIG. 4 includes a long curved groove 310 on the nip arm and a short groove 311 on the stationary nip arm 35 so that most of the bent resilient member 36 is inserted into the long groove 310 while the portion not inserted thereinto is inserted into the short groove 311 at one end. Since the nip arm 34 is movably engaged with a fulcrum A fixed .to the holder plates 31 and 32, the yarn gripping portion 340 is held by the biasing force of the resilient member 36 so that the yarn grippers 34a and 35a pass through the yarn guide groove at the end 33a so as to be disposed parallel with the flying direction of the yarn carrier.
- the yarn gripping portion 34a of the nip arm 34' is always urged against the yarn gripping portion 3501 by means of the biasing force of the resilient member or curved spring 36', which has one end inserted into the short groove 311 provided at one end of the stationary nip arm 35 and has its other end inserted into the long groove 310' of the nip arm 34' near the end opposite the engaging point of the end 34fof the nip arm 34' and gauge plate 39.
- 53a of the device is provided in contact with the area of the. small hole 51d, of the tube 51.
- 53b is a pipe or tube connected to a pressure reducing device provided separately and not shown.
- 54 is a yarn gripper using electromagnets for intermittently gripping the weft yarn F.
- the nip arms 62 and 62' may open or close at the fulcrums 64 and 64 as a center so that the yarn grippers 62a and 62a of the nip arms are depressed by the leaf springs 65 and 65.
- this invention provides apparatus for supplying weft yarn directly into the shed by gripping the end of the weft yarn by a yarn carrier in a loom which includes one or more yarn ejecting means for ejecting a plurality of weft yarns by ejecting or suctioning and drawn from a plurality of cheeses disposed at one or both sides of the loom at the initial flying position of the yarn carrier with one or more yarn and holding means for holding the end of the weft yarn, and having a plurality of weft yarn elevational guides disposed between the yarn ejecting means and cheese and between a plurality of yarn gripping means and the yarn ejecting means.
- the yarn carrier 75 reaches the other yarn carrier receiving device (not shown), and, upon completion of the weaving of the warp yarn into the weft yarn, the electromagnets 79g are de-energized simultaneously, whereby weft yarn F l is again depressed by the force of the biasing member 79h on the gripping plate 79a and stationary yarn gripping plate 79e. Further, the weft yarn cutter 84 also operates simultaneously to cut the weft yarn F1.
- said holding means including a suction fluid flow for holding said yarn end in the flowing direction by said suction force of fluid
- said yarn carrier further comprising nip arms including two arms and having a yarn gripping portion thereon for gripping the yarn, said nip arms actuated by depressing said arms by the force of a resilient biasing means located at the front of said yarn carrier with respect to the feeding direction of the yarn carrier, and exterior means for forming a gap for passing the yarn freely upon release of the depression of the yarn gripping portion, when the yarn carrier is depressed by applying an exterior force against said biasing force, said yarn gripping portion including a convergent width from the front of said yarn carrier to the yarn gripping portion in the feeding direction of the yarn carrier, a flared end in the same direction as the opening of said gripping portion, and a yarn guide groove for guiding the yarn to said yarn carrier so that the connecting line between the end of the groove and the yarn grip
