Apparatus for taking up a bundle of filaments

Apparatus for taking up a bundle of filaments from a supply source and feeding the bundle into a container, the apparatus comprising:

• a rotary member mounted for rotation about a vertical axis and having an outer periphery and a guide passage that includes a vertical upper portion extending downwardly from an axial entrance opening at the top of the rotary member and a lower portion that comprises a gradually spreading passage joined to and bent smoothly outwardly from the lower end of the upper portion to a discharge opening at the outer periphery, the gradually spreading passage comprising a rotationally leading front wall and a rotationally trailing rear wall curved away from the leading wall, the arcuate distance of separation between points along the front and rear walls at equal radial distance from the axis being greater the greater the radial distance, and said discharge opening being defined by the surface of the gradually spreading passage and comprising a first area that is adjacent the front wall and is higher than a second area adjacent the rear wall, whereby the main part of the stream of compressed fluid emerges through the first area in a direction above the portion of the bundle of filaments in the container;
• and
• ejector means at the upper end of the guide passage to direct a stream of compressed fluid down the vertical upper portion of the guide passage to engage and entrain the bundle of filaments in the upper portion of the guide passage, the increasing arcuate distance of separation of the front and rear walls permitting the bundle of filaments to be pulled toward the rear wall away from the main part of the stream of compressed fluid.
