Thereafter, the bobbin on the temporary storage spindle is transferred to the bobbin holder. According to another exchange process, the bobbin on the spare bobbin frame is transferred directly to the bobbin holder after the bobbin on the bobbin holder has been transferred to the temporary storage spindle. Thereafter, the bobbin on the temporary storage spindle is transferred to the spare bobbin frame.
Method for exchanging a full roving bobbin stored on an individual bobbin support member of a spare bobbin support means for another roving bobbin on a bobbin holder of a textile machine in which roving is fed from the bobbins for processing in the textile machine, comprising:
