A controlled needle tufting machine for overtufting a secondary yarn into a base material having primary yarn therein includes feed rollers and take-off rollers for feeding the base material. The feed rollers and the take-off rollers each include a picker roll which engages the back-stitch surface of the backing material, i.e., the surface opposite to that from which the pile fabric extends, and not the face or pile extending surface.
