Abstract: The present invention relates to a 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.

Abstract: The invention provides an unwinder comprising: a frame; a fiber package holder affixed to said frame holding a package (10) of iber about a rational axis such that at least one fiber can unwind from said fiber package (0) in a direction defining an acute angle with the rational axis of the fiber package; a driven take-off roll (30) for unwinding fiber from the fiber package at a predetermined take-off rate; a first fiber guide (20) for directing fiber unwound from the fiber package (10), said first fiber guide positioned on said frame such that a distance (d) from the first fiber guide to the end of the fiber package (10) facing said first fiber guide, measured on the line defined by the rotational axis of the fiber package, is controlled in dependency of the level of tack exhibited by the fiber and an angle υ, defined by the intersection of imaginary lines corresponding, respectively, to the rotational axis of the package and the central axis of the fiber guide inlet orifice that is controlled in dependency of the level of tack exhibited by the fiber. The invention further provides a method for unwinding fiber.
