Abstract
A ribbon self-orienting device that is to be interposed between the source and the target of a traveling ribbon, either during winding of a ribbon into a traversed roll or during pay-off of a ribbon from a traversed roll. A pivoting frame is pivotally coupled to a frame support, at a pivot axis. First and second direction changing means coupled to the pivoting frame serve to change the direction of the traveling ribbon. A force transfer means transfers a transversely directed force, imparted by the traveling ribbon due to the ribbon traversing its traversed roll while under tension, to the pivoting frame causing the pivoting frame to move about the pivot axis. Other embodiments are also described.
Claims23
A ribbon reorienting device, to be interposed between a source and a target of a traveling ribbon, either during winding of a ribbon into a traversed roll or during pay-off of a ribbon from a traversed roll, the device comprising:
- a frame support;
- a pivoting frame that is pivotally coupled to the frame support at a pivot axis;
- first and second direction changing means for changing direction of the traveling ribbon, wherein the first and second direction changing means are coupled to the pivoting frame with the second direction changing means being closer to the pivot axis than the first direction changing means, and wherein the first and second direction changing means are to move as one with the pivoting frame about the pivot axis;
- and
- a force transfer means for transferring a transversely directed force that is imparted by the traveling ribbon due to the ribbon traversing the traversed roll under tension, to the pivoting frame causing the pivoting frame to move about the pivot axis.
A ribbon reorienting device, to be interposed between a source and a target of a traveling ribbon, either during winding of a ribbon into a traversed roll or during pay-off of a ribbon from the traversed roll, the device comprising:
- a frame support;
- a pivoting frame that is pivotally coupled to the frame support at a pivot axis;
- a first roller or bar and a second roller or bar, both coupled to the pivoting frame such that the second roller or bar is closer to the pivot axis than the first roller or bar;
- and
- a force transfer means for transferring a transversely directed force that is imparted by the traveling ribbon due to the ribbon traversing the traversed roll under tension, to the pivoting frame causing the pivoting frame to move about the pivot axis.
