Front and rear needle bars are provided with front and rear needles for inserting yarns into a backing material. An excess of front loopers are provided for the front needles and an excess of rear loopers are provided for the rear needles. The front loopers respectively face the rear loopers and are respectively aligned with each other. The needle bars are shifted laterally so as to provide longitudinal rows of tufts formed by the front needles providing spacing between the tufts of a longitudinal row which space is filled in by the tufts of rear needles.
