摘要： Apparatus and method for producing selected color or material sequences with a stack of transversely folded products. Slit product width webs are longitudinally folded and advanced by slow speed feed rolls to a plurality of anvil rolls and segments are retarded so that voids are created in each of two or more streams of segments that are synchronized to create a continuous series of segments on the surface of a common carrier cylinder. Single or doublefolds can be made during or after transfer to the carrier. Reduced web speed from each parent roll results in longer run time between roll changes. In another embodiment, a central intermediate frame permits use of a plurality of half width cutoff units cooperating with a full width hollow carrier cylinder for processing of wide parent rolls without intermediate off-line slitting and rewinding.

摘要： 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.
摘要翻译：使用多宽母辊的双折叠装置，用于生产彩色排序的餐巾纸，包括用于展开，切割并将相同颜色的产品幅带推向转向和车道分离装置的装置，以选择性地将第一色织物转移到两个折叠车道，并选择性地将第二色网转移到另一条车道。叠加并排进行的第一和第二色幅料被压印，并且相同颜色的纸幅被引导到双折叠的一侧，用于纵向折叠，切割和横向折叠，而第二色织物在另一方处理侧面的双文件夹。一种颜色的餐巾重叠在第二种颜色的餐巾上，并作为一对在递送带之间交付用于包装成具有交替颜色的餐巾的堆叠。两个相邻的交付车道提供相同混合颜色的堆叠。在具有四个输送通道的机器中，第一和第二通道可以具有交替的第一和第二颜色，而第三和第四通道可具有交替的第三和第四颜色叠层。其他实施例包括展开架的不同放置，母辊颜色的布置以及其它转向和车道改变装置。
