1. A yarn feed mechanism for feeding yarns to the needles of a tufting machine comprising:

  • (a) a frame assembly having yarns passing adjacent thereto;

    (b) a yarn feed roll mounted for rotation on said frame assembly, said roll having an axis about which said roll is rotated and a yarn driving periphery;

    (c) a movable yarn applying member carried by said frame and disposed adjacent to said roll, and means for moving said yarn applying member with respect to said roll from yarn receiving position in which intermediate portions of said yarns are received by said yarn applying member,to a yarn applying position in which said yarn applying member applies increments of said yarns against portions of said periphery of said roll sufficiently that the rotation of said roll drives said yarns toward said needle;

    (d) said yarn applying member including a yarn control rod and rod support on said frame for supporting said rod in a position spaced from and about parallel to the axis of said roll, said yarns being looped partially around said rod and said rod being positionable for holding a portion of said yarns against only a part of said periphery;

    (e) said support including a pair of opposed plates removable supporting said rod therebetween;

    (f) said plates being concentrically mounted with respect to said roll for independant rotation with respect thereto and said rod being supported in spaced relationship to said roll for orbital movement with respect to said roll.
