  • the off-folded napkin 100 includes an off-fold 102 between the opposite edges 1 12, 1 16 of the front and back parts.
  • the front portion or part of the napkin 100 shown on top in FIG. 2 is shorter than the back portion or part of the napkin 100 on the bottom.
  • the napkin 100 may be configured such that the off-fold 102 is about one-half inch such that the off-fold 102 is either exactly one-half inch or about one-half inch where the difference above or below one-half inch is within manufacturing tolerances.
  • the napkin 100 may be configured such that the off-fold 102 is about one centimeter such that the off-fold 102 is either exactly one centimeter or about one centimeter where the difference above or below one centimeter is within manufacturing tolerances.
  • the napkin 100 may be configured such that the off-fold 102 falls within a range from about four-tenths of an inch to about six-tenths of an inch, etc.
  • the inventor hereof has recognized that purposefully and controllably providing a sufficiently large off-fold 102 ⁇ e.g., one-half inch, one centimeter, within a range from four-tenths of an inch to six-tenths of an inch, etc.) allows a user to more easily grasp and separate the opposing front and back parts of the napkin 100 at the off-fold 102. This, in turn, allows the user to more easily open the napkin 100.
  • a sufficiently large off-fold 102 e.g., one-half inch, one centimeter, within a range from four-tenths of an inch to six-tenths of an inch, etc.
  • the napkin 100 is single ply and foldable about first and second folds 104, 108.
  • the first and second folds 104, 108 are generally perpendicular to each other.
  • the first and second folds 104, 108 may be perpendicular.

  • the first fold 104 extends in a first linear direction between a first pair of opposite edges 120, 124 of the napkin 100.
  • the first fold 104 may also be generally referred to as longitudinal fold or interfold that extends longitudinally in a machine direction as described hereinafter.
  • the second fold 108 extends in a second linear direction generally perpendicular to the first linear direction.
  • the second fold 108 extends between a second pair of opposite edges 1 12, 1 16 of the napkin 100.
  • the second fold 108 may also be generally referred to as a cross fold described hereinafter.
  • the napkin 100 is thus foldable twice (cross-folded or quarter folded) once about each of the two generally perpendicular axes or folds 104, 108.
  • the napkin 100 may first be foldable about the first fold 104 into a single- folded configuration with the off-fold 102 between the first pair of opposite edges 1 12, 1 16, and thereafter foldable about the second fold 108 into a quarter-folded or cross- folded configuration having the off-fold 102 between the first pair of opposite edges.
  • the napkin 100 includes four panels or parts 128, 132, 136, and 140 cooperatively defined by the first and second folds 104, 108.
  • the napkin 100 is configured such that the first and second folds 104, 108 do not bisect the napkin 100 into four equal parts.
  • the first fold 104 is not along a centerline axis of the napkin 100. Instead, the first fold 104 is located closer to the edge 1 12 than to the edge 1 16 as shown in FIG. 1 . Accordingly, the napkin 100 is off-folded and includes the off-fold 102 as shown in FIGS. 2 and 3.
  • the panels or parts 128, 132 are one-half inch longer (from top to bottom in FIG. 1 ) than the panels 136, 140 in order to provide the one-half inch off-fold 102.
  • the first fold 104 is one-half inch closer to the edge 1 12 than it is to the edge 1 16 in this example shown in FIG. 1 . Therefore, and as shown in FIG. 2, the napkin 100 may thus be folded along the first fold 104 into unequal parts such that the napkin 100 has a one-half inch off-fold 102 in this example.
  • the panels or parts 128, 132, 136, 140 may all have about the same width (from left to right in FIG. 1 ).
  • the second fold 108 may be along or coincident with a centerline axis of the napkin 100 such that second fold 108 is equidistant from the edges 120, 124 in this example shown in FIG. 1 .
  • the napkin 100 may be folded a second time along the second fold line 108 after it has been folded along the first fold line 104.
  • the folding of the napkin 100 along the second fold 108 may align or substantially align the edges 120, 124 such that there is not a significantly sized off-fold ⁇ e.g., no off-fold, relatively small off-fold less than one-half inch, etc.) between the edges 120, 124.
  • FIGS. 1 through 3 show the exemplary manner by which the unfolded napkin 100 may be folded.

  • An exemplary embodiment of a napkin disclosed herein may first be folded in a first direction longitudinally or parallel in the machine direction, and then folded transversely in a cross direction.
  • the machine direction, longitudinal folding may be accomplished by using a technique generally referred to as plow folding.
  • a paper web is pulled or drawn ⁇ e.g., via driven feed rolls, etc.) from a roll over a stationary plow ⁇ e.g., fold pan or former, folding rods or guide bars, etc.).
  • the plow folds the paper web longitudinally along a line that is parallel to the direction of travel of the paper web.
  • the paper roll, the stationary plow, and feeding mechanism are specifically configured ⁇ e.g., located relative to each other, etc.) such that the plow folds the paper web in half into equal parts along the paper web's centerline, which centerline bisects the paper web and is parallel to the direction of travel of the paper web.
  • the inventor hereof has developed and discloses exemplary embodiments of modified plow folding processes for making his off-folded napkins.
  • the plow, paper roll, and/or feed line are configured ⁇ e.g., intentionally misaligned, positioned relative to each other, etc.) such that the plow is not located along the centerline of the paper roll. Instead, the plow is spaced apart from the centerline of the paper roll so that the plow off-folds the paper web ⁇ e.g., off- folded by one half inch, one centimeter, etc.) as the paper web travels over the stationary plow.
  • the off-fold is accomplished by intentionally misaligning the paper roll relative to the plow so that the longitudinal fold line created by the plow is not centered relative to the paper web.
  • the feeding process ⁇ e.g., rollers, edge guide tracks, etc.
  • the feeding process may be configured to controllably steer the paper web ⁇ e.g., controllably steer the paper off- course and not merely due to some uncontrollable or uncertain variation or manufacturing tolerance, etc.) so that the paper web arrives at the plow un-centered. Because the paper web is un-centered at the plow, the plow off-folds the paper web in an exemplary embodiment.
  • the plow itself may be geometrically configured ⁇ e.g., shaped, sized, etc.) to off-fold the paper web without having to reposition or realign the paper roll or plow in an exemplary embodiment.
  • the off-folded paper web may then be cut to form individual or discreet sheets in an exemplary embodiment.
  • the sheets may be transferred to a folding section that includes mechanical folding cylinders or drums.
  • the sheets are folded transversely in the cross direction as the sheets are transferred from one cylinder to another, thereby providing the sheets with second fold lines or cross folds. Transfer of the folded sheets may take place by grippers, pushers, and/or vacuum.
  • the folded sheets may be grabbed by mechanical grippers and tuckers that overlap the sheets from each line of the machine and create an interfold at the interfold line.
  • FIG. 4 illustrates a stack 144 of off-folded napkins 100, which have been interfolded to form the stack 144.
  • the napkins 100 in the stack 144 may each be off-folded to have an off-fold of one-half inch or about one-half inch.
  • Each napkin 100 in the stack 144 may or may not have the same off- fold equal to the off-fold of each other napkin 100 in the stack 144.
  • there may be some manufacturing tolerance and variability in the manufacturing process ⁇ e.g., a repeating drift in the folding operation, etc.), such that each napkin 100 does not include exactly the same off-fold.
  • the napkins 100 in the stack 144 may have off-folds falling within a range, e.g., four-tenths of an inch to six-tenths of an inch, etc.
  • each napkin 100 includes at least one pair of panels or parts that are disposed or sandwiched between a pair of adjacent panels or parts of another one of the napkin 100 in the stack 144. More specifically, this exemplary embodiment includes each napkin 100 within the stack 144 receiving between its two inwardly facing adjacent parts or panels a pair of adjacent parts or panels from each of two napkins 100 disposed immediately above and below it in the stack 144. Preferably, each napkin 100 is detachable and/or entirely detached from the other napkins 100 in the stack 144. Each napkin 100 is also oriented oppositely from each preceding and succeeding napkin 100 with the stack 144.
  • FIG. 5 illustrates a stack 144 of interfolded napkins 100 loaded into a dispenser 148.
  • the napkins 100 and dispenser 148 are configured such that the napkins 100 will be dispensed or drawn one at a time during regular use. While a user may be able to remove more than a single napkin by improperly using the dispenser 148, the configuration of the napkins 100 and dispenser 148 inhibits users from removing more than one napkin 100 at a time from the dispenser 148. As shown in FIG. 5, only a portion of a single napkin 100 extends or protrudes out of the dispensing opening 152 in the faceplate 156 of the dispenser 148 at a given time.
  • the dispenser 148 and interfolded napkins 100 may be configured to provide one napkin- at-a-time dispensing, which, in turn, may provide up to a fifty percent reduction in napkin usage when compared to usage of smaller tall fold styles and up to a thirty percent reduction in napkin usage when compared to usage of larger standard styles.
  • This exemplary one-at-a-time napkin dispensing configuration may help ensure that patrons use fewer napkins and touch only the napkin they use, thus improving personal hygiene.
  • This exemplary one-at-a-time dispensing may help decrease consumption, thus reducing the number of napkins needed to be stored at a restaurant, etc.
  • the napkins 100 may be provided in a case, such as six thousand napkins per case in which there are twelve stacks or packs each with five hundred interfolded napkins.
  • the napkins 100 may be configured such that one thousand five hundred fifty of such cases may fit within a standard forty foot container.
  • the napkin 100 may be configured with a rectangular configuration having a long side measuring 12.5 inches (or thereabout) and a short side measuring 8.25 inches (or thereabout) when unfolded and opened. When fully folded and closed, the napkin 100 may still have a rectangular configuration and have a long side measuring 6.5 inches (or thereabout) and a short side measuring 4.125 inches (or thereabout).
  • this exemplary embodiment of the napkin 100 when folded includes one fold 108 that bisects the napkin into equal (or about equal) parts where the fold 108 is 4.125 inches (or thereabout) from the napkin's edges 120, 124 parallel to that fold 108.

Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
