ABSTRACT:
A tubular yarn package (10) is disclosed of the type held by at least one end on a rotatably mounted plate. The plate fits into one end of package (10) and traps across the end against an inner wall of the package a length of yarn. Short length of spirally extending grooves (15) are formed in the inner wall of the package (10) adjacent to the end of the package. The yarn fits into the closest adjacent groove (15) and grips the yarn sufficiently to prevent breakage of the yarn by relative movement between the package (10) and the plate occasioned by starting or stopping the rotation of the package (10).
