Bobbin conveying system for a spinning machine

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.

A ring spinning machine is provided with a carrier rail extending along each row of spinning stations for slidably guiding peg trays. A guide rail is secured to the carrier rail for receiving connecting pieces in snap-fitted relation which serve to move the peg trays along the carrier rail. The connecting pieces are secured to a vertically disposed conveyor belt so that the conveyor belt is guided by the connecting pieces along the spinning stations.
