ABSTRACT:
A yarn support tube for supporting elastomeric yarns of the type having finish oil or emulsion applied to the yarn includes a tube core of paperboard, and an outer ply formed by spirally winding a laminated strip onto the tube core such that a butt joint is formed between edges of adjacent spiral turns of the strip. The laminated strip is formed of an inner paper layer and an outer layer of polypropylene film or the like which is substantially impervious to the finish emulsion. A sealing strip of polypropylene or the like, also substantially impervious to the finish emulsion, is spirally wound onto and adhered to the outer ply of the tube such that the strip spans and sealingly covers the butt joint. The sealing strip and polypropylene film layer cooperate to prevent finish emulsion from migrating into the tube core.
