PURPOSE:Full bobbins in the front and the back rows of the roving frame are set to bobbin holders for the front and the back rows of the conveyer, respectively by means of a doffer, then transferred to the bobbin carriers for the front and the back rows, respectively, by means of a transfer machine, then set to the creels of the spinning frame for the front and the back rows, respectively, to reduce uneveness in yarn thickness. CONSTITUTION:Bobbin doffer 11 doffs full bobbins A in the front and back rows of the roving frame 1 to the bobbin holders 9 on the front and back rows of conveyors 6, respectively. Then, the transfer machine 69 transfers the full bobbins to the bobbin carriers 27, 28 for the front and back rows corresponding to the rows in the holders 9. The bobbins are set to the creels for the spinning frame so that the bobbins in the front row are distinguished from those in the back row and the spinning frame is operated according to the difference between them to reduce fluctuation in yarn thickness. |
