ABSTRACT:
A ribbon gathering and folding assembly including a plurality of guide rollers positioned in superimposed relation to each other, the guide rollers being adapted to guide a ribbon, and a ribbon former including a former board that is positioned to receive ribbons from the guide rollers. The former board has a longitudinally extending forming surface that is positioned such that a direction of each ribbon travelling between the guide rollers and the former board is always within about 35 degrees of the forming surface. The ribbon former further includes a former roller positioned to guide the ribbons travelling from the guide rollers to the former board, and preferably also a control roller positioned between the former roller and the guide rollers on an opposite side of the ribbons from the former roller. A coating device is positioned to coat a low friction substance (e.g., silicone) onto a the upper surface of the upper-most ribbon and another coating device coats the lower surface of the lower-most ribbon.
