A device for engaging and tensioning a glass ribbon includes a center frame member, and first and second outer frame members connected thereto. The first outer frame member includes a suction cup that engages an edge area of the glass ribbon and an actuator for moving the suction cup of the first outer frame member. The second outer frame member includes a suction cup that engages an opposite edge area of the glass ribbon and an actuator for moving the suction cup of the second outer frame member. The actuators of the first and second outer frame members moves the suction cups of the respective frame members in directions away from each other.
