TITLE PLURAL CYCLE TRAVERSE ROLL ABSTRACT A cylindrical-bodied yarn package wound on a bobbin in layers of helical coils which appear in a repeating program having stable curved reversals separated circumferentially by a finite distance, sub- stantially all the crossings occurring in the curved reversals intersect at angles greater than the angles at yarn crossings occurring in the helical portions of the yarn path. The yarn paths involve at least three cycles in which yarn is wound in a program at a constant helix angle between reversals but a plurality of helix angles are included in the program. DP-3195
