Definitions

  • This invention relates to the production of rayon yarn having denier variations and is more particularly concerned with the production of rayon yarn having zones of low denier occurring at regular intervals along its length.
  • Figure l is a diagrammatic view in side elevation of a single spinning position equipped with apparatus constructed in accordance with the present invention for producing regularly occurring denier variations in the yarn;
  • Figure 2 is a view in front elevation of the apparatus of Figure 1;
  • Figure 3 is a detailed View showing one position of a cam that is employed in imparting denier variations to the yarn.
  • Figure 4 is another view of the cam of Figure 3 in a diierent position.
  • the yarn issuing from a spinnerette IIJ is led upwardly through a thread guide Il, in tangential contact with a pair of closely spaced rollers I2 and I3 arranged in vertical alignment ⁇ over the roller I3, and under an adjacent laterally spaced roller I4 from which the yarn is led to a draw off surface I5 of a stepped godet I6 which includes also a larger draw off surface I'I and a sloping guide roller I8.
  • a panel 20 is provided on which the rollers I2, I3 and I4, as well as the sheave I9, are mounted.
  • the axis of the sheave is slightly horizontally offset with respect to the yarn path between the rollers I2 and I4.
  • Accommodated in this offset and attached to the sheave I9 for rotation therewith, is a cam 2
  • roller I6 spaced from, but in the same horizontal plane as the roller I3, resultsI in imparting to the yarn a very marked change in direction in its passage between roller Ili'and the surface I5 of the stepped godet I6. rihis change in direction causes the cam produced stretch to take place between the spinnerette I0 and the roller I3 while the thread is still quite soft and deformable and prevents the stretch from being felt to any appreciable extent between the roller I3 and the godet I6. It is also desirable that the cam 2
  • Apparatus for the production of yarn having denier variations comprising a spinnere'tte, a draw off device for drawing yarn from the spinnerette, means for periodically altering the length of the yarn path between said spinnerette and said draw ed device to impart denier variations to said yarn, and means directing said yarn, after the denier variation has been imparted thereto, in driving relation to said length-altering means.
  • Apparatus for the production of rayon yarn having denier variations comprising a spinnerette, a draw oif device for drawing yarn from the spinnerette, a mechanism including a cam for periodically altering the length of the yarn path between said spinnerette and said draw oii device to impart denier variations to said yarn, and means directing said yarn, after the denier variation has been imparted thereto, in driving relation to said cam.
  • Apparatus for the production of rayon yarn having denier variations comprising a spinnerette, a draw oil device for drawing yarn from the spinnerette, a pair of spaced rollers in the yarn path between said spinnerette and said draw off device, yarn driven means for periodically altering the length of the yarn path between said rollers to impart denier variations to the yarn, and means directing said yarn, after the denier variation has been imparted thereto, in driving relation to said length-altering means.

  • Apparatus for the production of rayon yarn having denier variations at regular intervals along its length comprising a spinnerette, a rst draw oi means, a second draw off means and rotatable means including a driving sheave for a1- tering the length of the yarn path between said spinnerette and said first draw off means, theI driving sheave of said rotatable means lying in the yarn path between the first and second draw off means whereby the rotatable means is driven by the yarn at a rate correlated with the rate of yarn travel.
  • Apparatus for the production of rayon yarn having denier variations at regular intervals along its length comprising a spinnerette, lrst and second draw off means, a pair of spaced rollers in the yarn path between said spinnerette and said first draw oi means and a cam including a, driving sheave for altering the length of the yarn path between said rollers, the driving sheave of said rotatable means lying in the yarn path between said rst and second draw olf means whereby the cam is driven by the yarn at a rate correlated with the rate of yarn travel.
  • Apparatus for the production of rayon yarn having denier variations at regular intervals along its length comprising a spinnerette, draw oi means, a pair of vertically spaced rollers, a third roller laterally spaced from said pair of rollers, all of said rollers lying in the yarn path ybetween said spinnerette and said draw 01T means, said third roller lying close to said pair of rollers the yarn path between said pair and said draw @ii device, and yarn driven means for periodically altering the length of the yarn path between the rollers of said pair.
  • Apparatus for the production of rayon yarn having denier variations at regular intervals along its length comprising a spinnerette, rst and second draw ofi' means, a pair of spaced rollers disposed vertically above the spinnerette in the yarn path between the spinnerette and the first draw off means, a third roller laterally spaced said pair of rollers and lying in the yarn path between said pair of rollers and said rst draw ofi" device in closely spaced relation to the former, and a cam for altering the length of the yarn path between Isaid pair of rollers, said cam having a driving sheave lying in the yarn path between said iirst and second draw 01T means whereby the cam is driven by the yarn at a rate correlated with the rate of yarn travel.
