The main carriage of the apparatus is resiliently track-mounted closely adjacent the spinning machine, at approximately the spindle-rail elevation, for stable bi-directional movement along opposite sides and about at least one end of the machine. The carriage includes an open center section which facilitates its movement about the end of the machine, and which partially encloses and protects various extendable and retractable servicing mechanisms while permitting unimpeded movement and convenient maintenance of such mechanisms. Housing-like sections of the carriage fully enclose various drive and control components, which are so located as to provide a desired distribution of weight relative to the carriage supporting track. A mast section extends upwardly to an overhead rail which supplies electric power to the carriage and laterally stabilizes it.
