Abstract
A tufting machine needle module having a body member attachable to the needle bar of the tufting machine. The module has a plurality of longitudinally spaced needles formed integrally with the body member and depending therefrom in parallel relationship. The body member includes co-operable male and female formations on respective front and rear faces thereof spaced at equal distances longitudinally on the respective face with those of one face offset longitudinally relative to those of the other face by a distance equal to an odd number multiple of one-half the pitch of the needles carried by the body member. The modules are arranged in two rows one behind the other with the male and female formations of modules in respective rows cooperating with those of the other row so that the modules in a row are offset from the modules in the other row by one-half the pitch of the needles on each module.
