  • Compact single mandrel creel for over end take-off thread delivery
    Patent number: 7731119
    Abstract: The present invention compact creel using the OETO method that accommodates an increased number of packages in a relatively small footprint while providing a straight in-line delivery path in which fiber bends and changes in direction are minimized. In addition, the present invention is a system, apparatus and method for tension control in a fiber feeding system that provides a fast and reliable method for feeding high tack elastomeric thread or fiber from a package to a manufacturing process. Furthermore, the present invention provides a method and apparatus for changing packages on a creel without interrupting the manufacturing process. In particular, the compact creel of the present invention provides for continuous operation of unwinding and fiber delivery by allowing a standby package to be loaded on the same mandrel as an active package that is presently being unwound.
