ABSTRACT:
A doffing apparatus for a spinning frame having bobbin spindles arranged at equal pitch, comprising a movable frame carrying bobbin-chucking means and bobbin-deflecting means, and bobbin-conveying means, said apparatus being operative so that full bobbins from the spinning frame are transferred onto the bobbin-conveying means by said bobbin-chucking means in exchange with the empty bobbins brought by this bobbin-conveying means, without causing any interference, due to the action of the bobbin-deflecting means, between the full bobbins passing from the spinning frame onto the bobbin-conveying means and the empty bobbins being supplied from the conveying means to the spinning frame, thus minimizing the number of steps of doffing operation and the number of parts of the doffing apparatus as a whole.
