ABSTRACT:
A bobbin exchange system applied to a ring spinning frame provided with a unique creel mechanism, wherein a pair of parallel rails is provided for supporting respective bobbin carriages. Each bobbin carriage is provided with two alignments of bobbin hangers, to a number which is identical to a number of spindles of each side of the ring spinning frame. When roving bobbins supported by the bobbin carriage supported by one of the above-mentioned supporting rails reach an almost exhausted condition, a roving bobbin exchange operation between full packaged roving bobbins suspended by the corresponding bobbin hangers of the other bobbin carriage supported by another supporting rail is carried out, and upon completion of the above-mentioned roving bobbin exchange operation, the first-mentioned bobbin carriage is discharged from the first-mentioned supporting rail and then a fresh bobbin carriage supporting full packaged roving bobbins is introduced into the first-mentioned supporting rail by means of a conventional bobbin carriage transporting system. The above-mentioned roving bobbin exchange operation is repeated between the above-mentioned two supporting rails without stopping the spinning operation.
