Abstract
A tufting machine including a reciprocating needle bar carrying needles has a yarn jerker including a stationary adjustable yarn guide and a combination yarn jerker and threader carried by the needle bar. The jerker-threader has a substantially U-shape configuration with little mass offset from the needle bar. At least one arm of the jerker-threader is substantially parallel to the axis of elongation of the needles. The stationary guide has a leg which is also substantially parallel to the axis of elongation of the needle. The stationary yarn guide, the jerker-threader and the needles each have eyelets parallel to one another. The jerker-threader and the yarn guide are spaced apart by a relatively small distance and are offset one from the other. The construction permits the apparatus to occupy only a small amount of space in the tufting machine and has very little mass offset from the needle bar in comparison to prior yarn jerker systems.
