Definitions

  • the pulling device includes a stationary yarn guide transversely intersecting the line extending between the nips of two drafting roller pairs which define a drafting field.
  • the stationary yarn guide cooperates with a revolving yarn guide which is adjacent said stationary yarn guide and slightly spaced therefrom in the direction of movement of the yarn and which also transversely intersects the line extending between the nips of the drafting rollers.
  • a stationary yarn guide in the form of a transverse rod 14 is attached to stationary tubular element 4 and extends diametrically through the bore of the tubular element at one end thereof and is normal to the yarn passing through the element 4.
  • the element 11 does not only support the needles forming the funnel 5 but also supports a yarn guide in the form of a transverse rod 15 extending diametrically with respect to the ring 11 and adjacent the rod 14.
  • the rod 15, however, is slightly spaced from the rod 14 to afford easy passage of the yarn 6 between the rods when the latter are parallel with one another as shown in FIG. 6.
  • the yarn may be introduced, for example, at the right side of the rod 14, which is stationary, and is in the position I indicated in FIG. 3 while the rods 14 and 15 are parallel.
  • the yarn remains on the right side of the rod 14 in FIG. 3.
  • the rod 15 rotating in the direction of the arrow shown in FIG. 3 pushes the yarn alongside the rod 14 into the position II shown in FIG. 3.
  • This pushing effect discontinues because the force component which is parallel with the stationary rod 14 becomes too small to overcome the frictional resistance when the angle a formed by the rods and shown in FIG. 5 decreases. Therefore, at continued rotation of the rod 15 toward the subsequent parallel position of the rods the yarn 6 assumes the configuration shown in FIG. 6, i.e., the yarn is diverted to the left (position III in FIG.
