ABSTRACT:
A method and apparatus for exchanging exhausted roving bobbins for full packaged roving bobbins applied to a conventional ring spinning frame provided with at least one roving supply rail arranged at a position in front of the spinning frame, at each side thereof, wherein a unit operation for exchanging exhausted roving bobbins suspended by front and back bobbin hangers, facing each other on a creel, for full packaged roving bobbins previously carried to the predetermined supply positions thereof on this supply rail, is carried out stepwisely from one side to the other side of the spinning frame along the creel, with regard to each pair of front and back bobbin hangers on the creel to which such a unit operation is to be applied, by utilizing only two pegs for temporarily supporting roving bobbins capable of changing the axial distance thereof between an axial distance (b) between the front and back bobbin hangers, facing each other on the creel, and an axial distance (a) between two adjacent bobbin hangers on the supply rail.
