As described above, according to the method of the present invention,
A pair of full bobbins before and after the spare rail and two before and after the spinning creel
Shino that exchanges Kodama bobbins in a row while transferring them in pairs
In the replacement method, the full bobbins removed from the spare rail in front and rear pairs are left and right pairs, and the outlet nozzle is
Raise and lower while keeping it aligned in the hand direction
The nozzle is delivered by handing over to the head and performing Shinotsu
Shinohata out of full bobbin without changing the arrangement of
Shino can be delivered to the head, the moving mechanism of the outlet nozzle can be simplified, and no change in the arrangement of the outlet nozzle is required.
Since so as to lift the yarn end finding nozzle have, when the full the machine frame longitudinally, the peg for Kodama bobbin adjacent
However, there is an advantage that the outlet nozzle can be mounted on the Shino exchanger regardless of the above.
