An improved method and apparatus are provided for picking up rapidly running filaments with an ejector type device which is operated by compressed air. According to the method, the filaments are caught and placed under the influence of the propulsion jets of the ejector no later than, and preferably before, the time when the filaments are cut. In one embodiment the apparatus for carrying out this method includes a lateral lead-in passage in the ejector for receiving filaments. The passage provides a path for the filaments, which path is inclined to the longitudinal axis of the ejector and extends from the inlet of the ejector, passes the exit openings of propulsion jets and leads laterally out from the propulsion tube of the ejector. In a second embodiment the ejector is provided with a lateral lead-in passage which is perpendicular to the longitudinal axis of the ejector. The passage provides a path for the filaments which by-passes the inlet to the ejector and extends past the exit openings of the propulsion jets. In this second embodiment, a second passage is also provided parallel to the longitudinal axis and perpendicular to the lead-in passage. This second passage provides a path for the filaments from the lead-in passage to the inlet of the ejector.
