A multi-needle quilting machine used, for example, to sew mattress ticking, filler such as foam, and backing together, the top having a desired sewn pattern thereon. The ticking/filler/backing are pulled straight through the quilter. A front needle bar and parallel rear needle bar spaced therefrom, the bars having needles at preselected locations, are moved left and right, with respect to the movement of the ticking/filler/backing, to create the desired pattern. The front and rear needle bars are operated in an out of phase relationship, that is, when the front needle bars are moving down, the rear needle bars are moving up. Also, movements of the needle bar cranks can be set such that the cranks for the front needle bars rotate in one direction and cranks for the rear needle bars rotate in the opposite direction. In sewing, loopers are moved left and right and, also, rocked front and back to create an oblong path. A spreader rotating shaft has a looper rotating shaft transverse thereto. Transverse gears on both shafts engage so that the rotation of the spreader shaft rotates the transverse shaft. A looper crank on each end of the spreader shaft, the looper cranks having off-set bores therein, is used to create the left and right movement of the loopers. Eccentrics are used to rock the loopers front and back.
