A modular tufting unit has a needle bar formed of a plurality of sections or modules with each section being capable of being rendered ineffective. The modular tufting unit has its yarn feed rollers divided into sections or modules. Each of the sections of each of the yarn feed rollers is the same length as the section of the needle bar with which it is aligned in the direction of movement of the yarn. When one of the needle bar sections is rendered inactive, the aligned sections of the yarn feed rollers also are rendered inactive.
