Abstract: An endless conveyor in a ring spinning machine comprises bobbin pegs for receiving full and empty bobbins which must assume an exact position in order in a predetermined bobbin change position of the endless conveyor to come into alignment with a spindle or bobbin support arrangement and thus ensure bobbin transfer from or to the bobbin peg. The endless conveyor is divided in the longitudinal direction into various sections which are connected by connecting links or locks of different length in such a manner that a plurality of bobbin pegs arranged on a section in the bobbin change position of the endless conveyor can be exactly aligned with the associated spinning points by inserting locks of different length or by changing the effective length of the locks at both ends.
