A method and an apparatus for simultaneously changing bobbins in a fly frame wherein flyers supported from above are arranged in a zigzag fashion in front and back rows. The method comprises supplying empty bobbins in a zigzag fashion on pegs mounted on a conveyor of a bobbin changing apparatus; advancing bobbin changing arms of the bobbin changing apparatus to full bobbins on the fly frame; simultaneously doffing the full bobbins; retracting the arms with the full bobbins while the conveyor is moved so as to pass the full bobbins through spaces between adjacent empty bobbins; inserting the full bobbins onto empty pegs of the conveyor; moving the conveyor to locate the empty bobbins at positions corresponding to the arms; advancing and lifting the arms to remove the empty bobbins from the pegs; further advancing the arms with the empty bobbins while the conveyor is moved so as to pass the empty bobbins through spaces between adjacent full bobbins on the conveyor; donning the empty bobbins on the fly frame; and retracting the arms.
