A turn-bar for adjusting orientation of a web comprising: a plurality of roll bars; wherein positions of at least two bars of said plurality of roll bars are movable with respect to a direction of travel of said web through said turn-bar; and wherein an orientation of said web passing through said plurality of bars is changed by adjusting said positions of said at least two bars without removal of said web from said turn-bar, such that, when the two bars that are movable with respect to the direction of travel of the web are in a first position, the web passes through said turn-bar without being inverted such that a same side of the web faces a first direction both before and after the web passes through the turn-bar, and when the two bars that are movable with respect to the direction of travel of the web are in a second position, the web is inverted such that a first side of the web faces said first direction before the web enters the turn-bar and a second side of the web faces said first direction when the web exits the turn-bar.
