Abstract: A turn-bar for adjusting orientation of a web includes a plurality of roll bars. Positions of at least two bars of the plurality of roll bars are movable with respect to a direction of travel of the web. An orientation of the web passing through the bars may be changed by adjusting a position of the at least two bars without removal of the web from the turn-bar. A method of selectively inverting or not inverting a web includes changing a position of at least two roll bars of a turn-bar apparatus with respect to a direction of travel of the web, where the web is not inverted by the turn-bar apparatus when the at least two roll bars are in a first position, and the web is inverted by the turn-bar apparatus when the at least two roll bars are in a second position.
