ABSTRACT:
The present invention concerns a method and apparatus for spinning using fiber bundles selected from a mass of loose fibers. The apparatus essentially consists of means for removing the fiber bundles comprising a perforated belt (8) and a retaining drum (5) enabling one end of the fiber bundles to be positioned in a fixed area (12) for formation of the thread in its initial stage (15). This fixed area comprises a screen beneath which there is disposed a suction device (13). A hollow twisting flyer (14) and a rotating drum (16) connected to a pressure roller (17) ensure that the thread in formation (15) is caused to rotate and move in translation. This apparatus constitutes an improvement upon open end machines.
