ABSTRACT:
A bundle (12) of hollow fiber (34) is formed by winding a length of hollow fiber around a core (38) from an arm (20) that is in a plane at an acute angle with respect to the longitudinal axis of the core and is between opposite ends of the core. Relative rotation is provided between the longitudinal axis of the core and the position of the winding arm. During winding of the hollow fiber around the core, there is an increase in the ratio of (a) the angular velocity of the wind and (b) the relative rotational velocity between the longitudinal axis of the core and the position of the winding arm. In this manner, the void fraction of radially-outward annuli of the wound bundle is less than the void fraction would be if the ratio remained constant.
