An individually controlled needle tufting machine has a reciprocable latch bar for latching and unlatching selective needle holders, each needle holder being guided between a pair of guide plates and carrying a respective needle so that each needle selectively may be driven by the latch bar. The guide plates each include a plurality of curvilinear ridges and the edges of the needle holder are curvilinear and are received within a respective spaced apart pair of ridges within which they are guided as the needle holder reciprocates. The plates include vertically spaced apart inserts within which the ridges are formed. The needle holder has a yarn clamp mounted internally adjacent the bottom and a leaf spring has a leg mounted externally of the holder and has a leg entering internally to act upon and urge the yarn clamp.
