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.

A process for making a fiber bundle, having a void fraction of radially outward annuli, comprising the steps of: providing a core having a longitudinal axis; winding at an angular velocity a length of the fiber around the core end over end from an arm in a plane that is at an acute angle with respect to the longitudinal axis of the core and is between opposite ends of the core; providing relative circumferential rotation between said core and the position of the winding arm; during winding of the fiber around the core end over end, increasing 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 whereby the void fraction of radially-outward annuli of the wound bundle is less than the void fraction would be if the ratio remained constant.
