Abstract:
1. A web inversion system for use in a continuous web imaging device, the system comprising: a first turn bar positioned to be partially wrapped by a substantially continuous web moving in a first direction with a first surface of the continuous web facing in a direction that enables the first surface to contact the first turn bar to turn the continuous web to move in a second direction perpendicular to the first direction; a second turn bar positioned to be partially wrapped by the continuous web directed from the first turn bar to turn the continuous web in a third direction that is opposite to the second direction; a third turn bar positioned to be partially wrapped by the continuous web directed from the second turn bar to invert the continuous web to enable the first surface to face in a direction opposite to the direction that enabled the first surface to contact the first turn bar and to turn the continuous web to enable the web to travel in the first direction, the second and the third turn bars are each supported for translation along an axis parallel to the second and third directions and the second and third turn bars are connected to each other to maintain a predetermined distance between the second and third turn bars when translated along the axis; and a single driver operatively coupled to at least one of the second and the third turn bars to translate the second and the third turn bars along the axis.
