  • the tufting machine as thus far described is quite con-. ventional and in its normal operation; when yarn or thread is supplied to the needles 24, will project pile loops of uniform height or length through the base fabric 28 to form a tufted pile fabric of conventional type and in which the pile is of uniform depth.
  • a pair of yarn feed rolls 43 and 44 are mounted parallel and nearly contiguous with each other on the front of the housing 10 in suitable bearings 45 and 46.
  • the rolls 43 and 44 are of equal diameter and are spaced apart from each other to form an interstice of approximately 0.006 inch to permit the passage of yarn.
  • Each roll is provided with equally spaced annular grooves, each of which is filled with a frictional substance, such as emery, to form a yarn gripping band 47.
  • the bands 48 forming the smooth surfaces between the annular grooves on the rolls are comparatively frictionless and adapted not to grip'a strand of yarn adjacent said surface.
  • the rolls 43 and 44 are so constructed that the yarn gripping bands 47 on each roll are staggered with respect to the yarn gripping bands 47 on the other roll.
  • an annular yarn gripping band 47 on one roll 43 will oppose a smooth'annular nongripping band 48 on the other roll 44.
  • the right-hand end of the shaft 49 supporting roll 44 is driven by gearing within gear box 50, which in turn is driven by pulley 51, belt member 52 and drive pulley 53 mounted on needle shaft 14.

  • each slot 92 guides a pair of yarn strands 93 to adjacent needles 24, so that twice as many needles may be employed as there are yarn shifting fingers 57, solenoids 62 and pattern fingers 84.
  • the length of the pattern drum 7]. is only half as long as would be required ifeach finger slot 92 carried only one strand of yarn 93. As best disclosed in Fig.
  • a yarn shifting finger 57 whichhas not been activated by its corresponding solenoid 62 guides its yarn 93 between an annular gripping band 47 on the front roll 43 and a non-gripping band 48 on the rear'roll 44. In such an event, the yarn 93 will be engaged by the slower front roll 43 to create a low nap in the base fabric 28.

  • a loop L is formed by the needle 24 first forming a loop L equal to the depth of penetration, and because of the shortage of the yarn provided by the slow speed feed roll 43, the needle withdraws a portion of the yarn from a previously formed loop so that the short nap is provided in the base fabric 28 by deficient loops L It is, of course, possible to form either a uniform high nap tufted fabric by completely removing the pattern sheet 81 from the pattern drum 71, or to form a uniform low nap tufted fabric by placing a pattern sheet 81 without any openings 82 on the pattern drum 71.
  • the yarn 93 may be drawn back as described, by the needle 24 alone operating on its penetration stroke to pull back yarn from a previously formed loop after all of the slack yarn between the feed rolls and the needle has been drawn into the loop being formed.
  • it is also possible to draw back the yarn by including in the needle mechanism a yarn or thread jerker 94 (Fig. 4), as previously described in Card application Serial Numher 327,807.

  • said yarn shifting means comprises a finger for each yarn gripping band on one roll pivotally mounted on one side of said rolls, slot means in said finger for guiding a yarn between a yarn gripping band of one roll and the opposing yarn slipping band of the other roll substantially perpendicular to the axes of said rolls, and means for selectively pivoting each finger to guide a yarn between opposing yarn gripping and slipping bands or between the adjacent opposing yarn slipping and gripping bands.
  • said slot means comprises the tip of said finger, said tip being located proximate to the yarn passage spacing between said rolls without touching said roll surfaces.
  • said finger pivoting means comprises a spindle, said finger being fixed to said spindle for limited rotational movement substantially axially of said rolls, a lever fixed to said spindle and an electro-magnet for actuating said lever to rotate said spindle.
