Guide to splicer 26.Here, coiler device 12 stops package P rotation.
On the other hand, as shown in figure 5, suction tube 27 turns to the downstream of spinning apparatus 7 and produces attraction stream.Now,
Because cell controller 10 starts again at drafting system 6 and the action of the grade of spinning apparatus 7, so, 27 pairs of suction tube is given birth to
Into spinning yarn Y yarn ends caught.Next, as shown in fig. 6, suction tube 27 turns to home position (standby position
Put), and the spinning yarn Y of the side of spinning apparatus 7 yarn ends are guided to splicer 26.
When the spinning yarn Y of the side of coiler device 12 yarn ends and the spinning yarn Y yarn ends of the side of spinning apparatus 7 are drawn
It is directed at after splicer 26, in yarn accumulation device 50, yarn hooking member 61 hooks the spinning yarn Y of the side of spinning apparatus 7, and
Spinning yarn Y is wound on to the yarn accumulation roller 51 rotated integrally.Thus, even if the winding carried out by coiler device 12 stops
Only, also hardly relaxed from the spinning yarn Y that spinning apparatus 7 is sent out.So, yarn accumulation device 50 can by
Connect yarn chassis 3 progress connect yarn action when etc. make from spinning apparatus 7 send out spinning yarn Y be detained so as to prevent spin yarn
Line Y relaxes.
When the accumulation amount of the spinning yarn Y on yarn accumulation roller 51 reaches lower limit amount, in yarn accumulation sieve
Draw and skidding etc. hardly occurs between 51 yarn reserving portion 52 and spinning yarn Y.Its result is, spinning yarn Y is from spinning
Device 7 is stably drawn (that is, with the quality of constant and the speed of constant).Cell controller 10 departs from yarn
Part 64 is moved to lifting position from down position, and yarn, which departs from part 64, makes spinning yarn Y depart from from yarn hooking member 61.
So, spinning yarn Y is made to depart from from yarn hooking member 61 in the state of yarn accumulation roller 51 rotates
Afterwards, the resistance for almost not preventing spinning yarn Y from being unwind from yarn accumulation roller 51.Thus, reached in spinning yarn Y accumulation amount
