Abstract: A process is disclosed for production of a heat-treated, coarse fiber of polyester-POY, whereby the fiber is first twisted and then continuously relaxed and tempered at a temperature from 130.degree. to 250.degree. C. to an extent from 20 to 55%. The slide-resistant fiber produced in this manner, displaying an elongation at break from 150 to 350%, a thermal shrink from +6 to -6% can be employed without further pre-treatment as weft yarn for tire cord webs.

Abstract: 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.
