SYNCHRONOUS DOFFER IN SPINNING FRAME

摘要

PURPOSE:The titled doffer that is provided with a plurality of bobbin holders which are driven by compressed air and with 2 or more exhausted valves on the pipe connecting between the holders and the air source, thus enabling the exhaustion operation to be speeded up. CONSTITUTION:Bobbin holders driven by compressed air 2 are set so that they correspond to individual spindles set on the spinning frame in rows and compressed air is fed from the compressed air source 6 to each bobbin holder to effect synchronous doffing. At this time, 2 or more exhausting valves 8 are set on the pipe line connecting between the bobbin holders and the air source.
