Abstract
Abstract The invention deals with improvements in doffing of yarn packages and insertion of bobbins (either conical or cylindrical) into the cradle mechanisms of operating stations of a yarn handling machine including definition of the insertion path, retention of the bobbin relative to the operating station while axillary operations such as formation of a thread reserve are performed, and control of the insertion operation in dependence upon the intended operation of the machine, for example continued operation of the station or shutdown thereof, the doffing and bobbin inserting operations being performable by a travelling service tender.
