PURPOSE:A bobbin exchanger provided with arms for exchanging bobbins that are reciprocally movable to the fly frame is used to effect the automatic setting of empty bobbins and ensuring the connection of the groove on the bobbins to the projection of the bobbin wheel. CONSTITUTION:After full bobbins are doffed, the bobbin exchanger 10 holds new bobbins 5A with the bobbin exchanging arm 32 and feeds them between the empty flier 3 and the bobbin wheel 7. The bobbin rail 6 rises from the lowest position to the one to start winding and the empty bobbin 5A is inserted into the guide leg 4 in the frier 3 and the connection part 8 in the bobbin wheel 7. At this time, if the connection groove 5b in the bottom does not connect to the projection on the bobbin wheel 7, the arm 32 is pushed up with the collar 5d and the bobbin wheel is made to revolve, as the empty bobbin is pushed down by its own weight or the force of a spring, to effect the complete fitting of the empty bobbin 5A to the bobbin wheel 7. |
