<p>A method for exchanging roving bobbins in a spinning frame, wherein a unit operation includes a series of step operations for exchanging a pair of almost exhausted robing bobbins (2B, 2F) suspended by front and back bobbin hangers (12) facing each other in the creel for two adjacent full packaged roving bobbins, corresponding to the above pair of roving bobbins (1), of the supply rail (13) arranged at a position in front and above the creel. The unit operation is intermittently but successively carried out along the spindle alignment of the spinning frame from one side-end to the other. In this unit operation, it is inevitable to use a pair of pegs (35, 36) for supporting a pair of roving bobbins in a manner allowing changing of the axial distance of these pegs between a distance identical to an axial distance between a front bobbin hanger and a back bobbin hanger, facing each other in the creel, and a distance indentical to an axial distance between two adjacent bobbin hangers on the supply rail (13). Also, an apparatus provided with a peg unit (40) having the above two pegs (35, 36) together with mechanism (60) for changing the axial distance between these two pegs. Th e apparatus is further provided with an additional mechanism (70) for displacing the peg unit to desired positions to carry out the unit operation for exchanging roving bobbins, and a mechanism (90) for displacing the apparatus along the spinning frame to carry out the successive unit operations for exchanging roving bobbins from one side-end to the other of the spinning frame.</p> |
