Abstract: A device for the non-reversed setting up of rod shaped bodies having ends of different thicknesses and particularly for orienting conical tubes for yarn spinning and twisting machines comprises a feed chute along which the bodies are fed with their sides adjacent and with their ends generally aligned. The feed chute includes an opening in which there are disposed two spaced apart supports oriented adjacent the respective ends of the tubes which are fed one after the other into the opening. Two pressing fingers are mounted so that they move through a path overlying the respective ends of the tubes simultaneously in a manner such that one of them only will contact the thicker end of the tube to begin moving it downwardly over the associated support.
