ABSTRACT:
This invention relates to a method and apparatus for integrating a newly formed continuous filament into a continuous strand. Mechanically complicated prior integration devices are usually expensive to purchase and operate and do not always ensure that the initially formed section of the new filament is separated from the new filament, that the fiber diameter of the new filament is predrawn sufficiently for ready integration, or ensure the reliability of the guiding elements facilitating integration. The present invention includes the operations of drawing a plurality of continuous filaments 3 from a bushing 1 into a fiber fan 4 by gathering the filaments 3 into a continuous strand 6 at a deflection point or roller 5. Should one of the filaments 3 break, a new continuous filament 8 is formed which is deflected by a guide plate 9 toward the point 5. A water stream 13 separates the filament 8 from its associated initially formed section and concomitantly predraws the filament 8 to an initial fiber diameter conducive to integration. The filament 8 is further predrawn and conducted by the stream 13 between guide bars 15 to a point 5 where the strand 6 and the filament 8 are jointly deflected along a common path X defined at least by the point 5 and another point or roller 7 such that the newly formed filament 8 is drawn to its final fiber diameter and integrated with strand 6.
