<p>TEXTILE YARN SUPPORTS A support for use in the winding of textile yarn in the form of a hollow cone molded from expanded polystyrene beads. The wall of the body is made up of a central cushioning structure and a harder skin. The skin has a microporous crust made up of a multiplicity of randomly distributed scales. The skin is slightly deformable by the action of strands applied under winding pressure so as to maintain a permanent set to the pattern applied by the strands.</p> |
