Abstract
A wireline cable winch drum is provided that includes a core having a longitudinal axis; a pair of flanges spaced apart and extending radially outwardly from the core; and a wireline cable wrapped around the core in the space between the flanges. In one embodiment, at least one of the flanges includes an inner surface that contacts the wireline cable and forms an angle with respect to the longitudinal axis of the core.
