(under subclass 430) Subject matter comprising a winding mechanism having means to develop longitudinal tension in a portion of the elongated material prior to winding, which tension is of such a magnitude as to exert an appreciable compression force on the core after winding.
(1) Note. Typically, the material is a relatively strong metallic or plastic cable applied to a core (e.g., a rotatable pipe or vessel or a stationary fluid reservoir) to strengthen the resulting article against internal pressure.
