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.
Claims16
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.
A web press system comprising:
- at least two print engines;
- and
- one or more turn-bars disposed between said print engines,
- each said turn-bar comprising:
- a plurality of roll bars;
- wherein at least two bars of said plurality of roll bars are movable with respect to a direction of travel of a web through said turn-bar;
- and
- wherein an orientation of said web passing through said turn bar is changed by adjusting a position of said at least two bars without removal of said web from said turn-bar, such that a web is not inverted with respect to said print engines when the at least two bars that are movable with respect to the direction of travel of the web through the turn-bar are in a first position, and the web is inverted with respect to said print engines by passing through said turn-bar when the at least two bars that are movable with respect to the direction of travel of the web through the turn-bar are in a second position.
