Provided for a spinning machine, a roving bobbin changing apparatus which includes a roving end finding/pick-up section equipped with a roving end finding/pick-up mechanism at a leading side as viewed in a direction in which the roving bobbin changing apparatus is moved for roving bobbin exchange, and a roving tying/bobbin exchange section equipped with a roving bobbin exchanging means at a trailing side. The roving tying device is so disposed as to be movable between the roving end finding/pick-up section and the roving tying/bobbin exchange section. The roving tying device can be moved by a belt to a new roving grasping position in the roving end finding/pick-up section and a roving tying position corresponding to that of a full roving bobbin transfer means in the roving tying/bobbin exchange section. Operations for finding and picking up roving ends from a pair of full roving bobbins disposed on an auxiliary rail and operations for tying the rovings and transferring the full roving bobbins after the roving tying to bobbin hangers of a creel of a spinning machine are carried out in parallel.
