Figure 12 is the time flow chart of the operating state of the above critical piece that illustrates of expression.As shown in Figure 12, after yarn guide rod 10 was just changeing, CD-ROM drive motor 50 was done and is revolved turn around (0 °～360 °).Turn around by revolving of this CD-ROM drive motor 50, plectane guide portion 20 is done to revolve and is turned around, and clamping device 22, cutting mechanism 23, nozzle cover 24 and yarn are pulled out drivings such as bar 25 simultaneously, carry out beginning to a series of action of finishing from joint.

As shown in Figure 7, in the present embodiment, at first first holding section 101 engages with the selection yarn Y1 that is in chosen position P1, and second holding section 102 engaging afterwards is made into yarn Y4, does not produce Y4 and moves laterally from the inboard of separator 12 thereby make.

Yet, for example (state that each figure of expression and Fig. 7 is corresponding) shown in each figure of Figure 13 is made into yarn for knitting yarn Y1, is to knit under the situation of yarn Y4 selecting yarn, second holding section 102 does not engage and is made into yarn Y1, selects yarn Y4 engaging to be made into yarn Y1 and moves laterally from the inboard of separator 12.Just, shown in Figure 13 A-1 and Figure 13 A-2, the state rotation of yarn Y4 is selected with engaging in first holding section 101, thereby selects yarn Y4 to move with the state from the outside of separator 12 to the inboard.Thus, be made into yarn Y1 before 102 engagings of second holding section, joining with selecting yarn Y4 to intersect engages.Under this state, yarn guide rod 10 is further rotated, thereby shown in Figure 13 B-1 and Figure 13 B-2, selects yarn Y4 to make to be made into yarn Y1 to move laterally from the inboard of separator 12.

Just, select yarn with after first holding section 101 engage, and be made under the situation that yarn intersects, the selection yarn engages and is made into yarn and moves to position of readiness P3, but not second holding section 102.Relative with it, select yarn with after first holding section 101 engages, and with being made into yarn under the uncrossed situation, second holding section 102 be made into that yarn engages and move to position of readiness P3.

In the above-described embodiment, though horizontal loom is narrated, also yarn switching device shifter involved in the present invention can be carried the yarn that chooses from multiple yarn is carried out in the fibre machinery of automatic splicer etc. of joint.
