Dual folding apparatus using multi-width parent rolls to produce color sequenced stacks of napkins, including means for unwinding, slitting and advancing same-color product webs to a turning and lane separating device to selectively transfer first-color webs to one of two ‘folding’ lanes and selectively transfer second-color webs to the other lane. First and second-color webs in superposed side by side advancement are embossed, and webs of the same color are directed to one side of a dual folder for longitudinal folding, cutoff, and transverse folding while the second-color web is processed in the other side of the dual folder. Napkins of one color are superposed on napkins of a second color and delivered as a pair between delivery belts for packout into stacks having napkins of alternating color. Two adjacent delivery lanes deliver stacks of the same mixed colors. In machines with four delivery lanes, first and second lanes can have alternating first and second colors, while the the third and fourth lanes can have alternating third and fourth color stacks. Other embodiments include different placement of unwind stands, arrangement of parent roll colors, and other turning and lane changing means.
Apparatus for producing napkin stacks having a plurality of color sequences, comprising:
The apparatus of cliam 3 wherein at least one of said turning bars for like-colored webs and is vertically separated from another turning bar that accepts and turns two other like-colored webs.
In a method of procesing staacks having a plurality of color sequences including the steps of:
