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 printing direction and to direct the continuous web in a second direction perpendicular to the first direction with a second surface of the continuous web facing in the printing direction; a second turn bar positioned to be partially wrapped by the continuous web directed from the first turn bar and to direct the continuous web in a third direction opposite the second direction with the first surface facing in the printing direction, the second turn bar being wrapped 180 degrees by the continuous web; a third turn bar positioned to be partially wrapped by the continuous web directed from the second turn bar and to direct the continuous web in the first direction with the second surface facing the printing direction, each of the first, second, and third turn bars comprising an idler roller; a frame supporting the first, second, and third turn bars, the frame including linear slides operably coupled to the second and the third turn bars to enable translation of the second and third turn bars along an axis parallel to the second and third directions, the second and third turn bars being connected to each other to maintain a predetermined distance between the second and third turn bars when translated along the axis; a pulley operably coupled to the second turn bar; a linkage cable wrapped around the pulley and having one end attached to the third turn bar and the other end attached to the frame; and a driver operably coupled to at least one of the second and the third turn bars and configured to translate the second and the third turn bars along the axis.
