Needle bar foot construction for multiple needle skip-stitch tufting machine
First Claim
1. In a tufting machine for forming skip-stitch, pile yarn patterns in a base fabric, including means supporting a base fabric for longitudinal movement in a feeding plane through said machine, a reciprocable drive member, a plurality of alternating first and second elongated needle bars, each of said needle bars having an operative end portion, means for latching engagement and disengagement of each needle bar to said drive member, and pattern control means for selectively actuating said latch means, the improvement comprising:
- a. a first foot member fixed to the operative end portion of each first needle bar,b. a pair of first needles supported in said first foot member for penetrating said base fabric with pile yarns to form a first pair of tufts therein when said first needle bar is latched to said drive member,c. a second foot member fixed to the operative end portion of each said second needle bar,d. a pair of second needles supported in said second foot member for penetrating said base fabric with pile yarns to form a second pair of tufts therein when said second needle bar is latched to said drive member, ande. said second foot member supporting at least one of said second needles in a vertical longitudinal plane between said pair of first needles.

Abstract
A multiple needle skip-stitch tufting machine in which each needle bar is provided with a needle foot member supporting a pair of needles. Each foot member includes a pair of arms, each arm supporting a needle in such a manner that the arms of the foot member of one needle bar interdigitate with the arms of the foot member of an adjacent needle bar to provide a relatively narrow gauge machine in which the skip-stitching is formed in pairs of tufted rows, and a row in one pair may be stitched between an adjacent pair of rows.
