Abstract: An assembly for transporting empty tubes and cops in a ring-spinning machine. Driven conveyor belts are disposed alongside rows of spindles disposed on both sides of the ring-spinning machine. The conveyor belts are driven for delivering empty tubes to and removing cops from the spindles, and the conveyor belts have openings formed therein at a mutual spacing approximately corresponding to half the given spindle spacing for securing arbors for alternatingly supporting empty tubes and cops. Instead of the arbors, however, at least every other opening supports a driver which engages one of a plurality of caddies at an indentation formed in a support surface thereof and entrains it along the conveyor belt. Each of the caddies carry an arbor for an empty tube and for a cop. The caddies have a length which is less than the given spindle spacing. Guide tracks extend along the conveyor belts and they guide the caddies along the conveyor belts.
