摘要： A doffing device is used in an open end spinning machine having a plurality of spinning units arranged side-by-side at a predetermined interval, a withdrawing roller for withdrawing a spun yarn from each spinning unit, and a split drum for traversing the withdrawn spun yarn for winding it on a bobbin. The doffing device includes a plurality of arms arranged along the machine, at such interval, between the withdrawing roller and the split drum. Each arm has at an intermediate portion thereof an empty bobbin supporting roller and at a free end thereof a plate spring with an empty bobbin pressing roller mounted on each plate spring. Each empty bobbin supporting roller has an intermediate flange to position end portions of two adjacent empty bobbins supported in adjacent empty bobbin receiving spaces formed by respective supporting rollers and pressing rollers in cooperation with the split drum.
