    • PURPOSE: To provide the subject method intended to compress yarn rolls with uniform density through such a practice that, yarns are cross-wound on mutually fittable and axially compressible yarn roll carrier tubes, a plurality of such tubes are jointed in series to form a column followed by exerting an axial compressive force thereagainst to mutually fit the individual tubes and then further exerting an axial compressive force against the column. CONSTITUTION: The subject tube, a sleeve-shaped yarn roll carrier tube, is made up of ring-shaped portions 1, 2 on upper and lower ends and a central portion 3; wherein the portion 1 consists of a ring 4 with a level difference part 7 projected inwardly, while the portion 2 is formed of a ring 5 with an outer diameter equivalent to the inner diameter of the ring 4; a column is then formed with a plurality of the above tubes each with a cross-wound yarn roll and subsequently subjected to an axial compressive force to mutually fit the individual tubes followed by further exerting a compressive force against the resultant column to effect contraction of the tubes and effect uniform compression of the yarn rolls as well.
