Abstract

The invention relates to a stack of fan folded material and related systems and processes. The stack includes at least two clips of fan folded material. Each clip includes a plurality of fan folded sheets, with each sheet joined to at least one adjacent sheet by a weakened line. Each clip is joined to an adjacent clip by a last sheet of one clip being separably joined to a first sheet of a succeeding clip.

Claims

1. A stack of fan folded material comprising:

at least two clips of fan folded material;

each clip comprising a plurality of fan folded sheets formed from a same web of material which travels in a length direction of the web of material, each sheet of the clip joined to at least one adjacent sheet by a weakened line wherein the weakened line is formed in the length direction of the web of material and the weakened line is located at an end of each sheet when such sheet joins the end of the adjacent sheet by the weakened line and the plurality of fan folded sheets comprise fold lines formed in the length direction of the web of material;

each clip joined to an adjacent clip by a last sheet of one clip being adhesively joined to a first sheet of a succeeding clip; and

the stack further comprising a liquid in combination with the stack of fan folded material, the liquid at an add-on rate of about 25 to about 600 weight percent based on a dry weight of the stack of fan folded material.

2. The stack of claim 1 wherein the weakened line comprises perforations.

3. A stack of fan folded material comprising:

at least two clips of fan folded material;

each clip comprising a plurality of fan folded sheets formed from a same web of material which travels in a length direction of the web of material, each sheet of the clip joined to at least one adjacent sheet by a weakened line wherein the weakened line is formed in the length direction of the web of material and the weakened line is located at an end of each sheet when such sheet joins the end of the adjacent sheet by the weakened line and the plurality of fan folded sheets comprise fold lines formed in the length direction of the web of material;

each clip joined to an adjacent clip by a sheet of one clip being separably joined to a different sheet of a succeeding clip; and

the stack further comprising a liquid in combination with the stack of fan folded material, the liquid at an add-on rate of about 25 to about 600 weight percent based on a dry weight of the stack of fan folded material.

4. The stack of claim 3 wherein the weakened line comprises perforations.

5. The stack of claim 3 wherein separably joined comprises adhesively joined.
