ABSTRACT:
A needle plate member for a multiple needle loop pile tufting machine including double needle bars supporting transverse rows of front and rear needles in which at least one row of needles has a narrow gauge. Finger members or needle plate fingers project rearward from the needle plate and extend rearward beyond the rear needles. The transverse spacing between each pair of needle plate fingers is equal to twice the needle gauge of the needles having the narrow gauge. The wider gauge or transverse spacing of the needle plate fingers permits the fingers to extend rearwardly through both front and rear transverse rows of needles to adequately support the base fabric moving through the machine and penetrated by both sets of needles, as well as guiding the front loops past the rear needles to minimize tagging.
