The ribbon core engager has a rotatable drive hub potion and a rotatable and axially movable positioning hub portion that are selectively rotatable about a hub axis to engage and correspondingly force rotation of a ribbon core when said drive hub portion is rotated. A motion converter connected to both said cover and said positioning hub permits movement of said positioning hub portion axially back and forth along said hub axis when said cover is correspondingly moved between said open and closed positions therefor.
