Abstract
A folded sheet is provided, suitable for advertising and informational material. The sheet has longitudinal and transverse directions, a left working edge, a right working edge, an upper edge, a lower edge, a front and a back. The sheet is foldable in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips. Each strip has substantially the same transverse width. The sheet is also foldable in concertina fashion about an even number of transverse fold lines between the upper and lower edges. The transverse folds are made before or after the longitudinal strips have been folded in concertina fashion, such that when folded the sheet comprises an odd number of folded panels. The sheet has a tab for manually gripping an edge of the sheet when folded. The tab is attached to a corner panel. The corner panel is on the outside of the sheet when folded about the longitudinal and transverse fold lines. The sheet, with integral tab, is die cut from a larger sheet. The sheet may also have integral extensions, e.g. tear-off coupons.
Description
FOLDED SHEET
Field of the Invention The present invention relates to folded sheets, particularly sheets for providing a compact means for presenting printed matter such as advertising material, maps and the like.
Background to the Invention Folded sheets are known for providing relatively compact maps and advertising material. For example, maps are commonly available on printed folded paper.
Z-Card (trademark) folded sheets are commercially available. They are disclosed in U.S. patent 5156898 which issued June 20, 1991 to E.W. McDonald. The Z-Card has an even number of panels in the transverse direction of the sheet and three panels in the longitudinal direction. On the back of the sheet, at diagonally opposing corners, there are cardstock or other stiff sheet members attached to the sheet. The stiff sheet members are marginally larger than a panel. In forming the Z-Card sheet, the sheet is first folded along longitudinal foldlines in a concertina fashion, i.e.
alternatively folding backwardly and forwardly. The thus folded sheet is then folded along transverse fold lines in a concertina fashion, so that the stiff members are on the front and back of the completely folded sheet.
In order to make the Z-Card folded sheet, the card-like members must be laminated, glued or otherwise be attached to the sheet in a separate step to the folding steps. The manufacture of such folded sheet systems requires three stages, i.e. printing and folding of the sheet, printing and die cutting of the card-like members ("end plates"), and aligning and gluing the end plates to the sheet. Specialized machinery is required and the product tends to be expensive.
A less expensive product has been sought, which the present invention provides. The present invention is also directed to providing an easy way to unfold the folded sheet.
Summary of the Invention Accordingly, the present invention provides a sheet with longitudinal and transverse directions, a left working edge, a right working edge, an upper edge, a lower edge, a front and a back;
said sheet being foldable in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips, each strip having substantially the same transverse width;
said sheet also being foldable in concertina fashion about an even number of transverse fold lines between the upper and lower edges, said transverse folds being made before or after the longitudinal strips have been folded in concertina fashion, such that when folded the sheet comprises an odd number of folded panels;
said sheet having a tab for manually gripping an edge of the sheet when folded, said tab being attached to a corner panel, said corner panel being on the outside of the sheet when folded about the longitudinal and transverse fold lines.
In one embodiment, the tab is an integral extension of the sheet.
In another embodiment, the sheet has an extension attached to the sheet at least on one location selected from i)the upper edge, ii) the lower edge; iii) the left working edge and iv) the right working edge, with the proviso that when attached to the right working edge, the extension is separated from the tab.
In yet another embodiment, the extension is attached to the sheet at an edge, wherein the edge is perforated and forms a fold line.

A less expensive product has been sought, which the present invention provides. The present invention is also directed to providing an easy way to unfold the folded sheet.
Summary of the Invention Accordingly, the present invention provides a sheet with longitudinal and transverse directions, a left working edge, a right working edge, an upper edge, a lower edge, a front and a back;
said sheet being foldable in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips, each strip having substantially the same transverse width;
said sheet also being foldable in concertina fashion about an even number of transverse fold lines between the upper and lower edges, said transverse folds being made before or after the longitudinal strips have been folded in concertina fashion, such that when folded the sheet comprises an odd number of folded panels;
said sheet having a tab for manually gripping an edge of the sheet when folded, said tab being attached to a corner panel, said corner panel being on the outside of the sheet when folded about the longitudinal and transverse fold lines.
In one embodiment, the tab is an integral extension of the sheet.
In another embodiment, the sheet has an extension attached to the sheet at least on one location selected from i)the upper edge, ii) the lower edge; iii) the left working edge and iv) the right working edge, with the proviso that when attached to the right working edge, the extension is separated from the tab.
In yet another embodiment, the extension is attached to the sheet at an edge, wherein the edge is perforated and forms a fold line.
In a further embodiment, the extension is perforated at the transverse fold lines.
In another embodiment, a corner panel adjacently opposite the tab corner has an extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet.
In a further embodiment, a corner panel which is adjacent to the tab has an extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet.
In yet another embodiment, the sheet and any extensions are die cut, as a single piece, from a larger sheet.
The invention also provides a process for making a folded sheet comprising:
a) cutting a foldable sheet from a larger sheet, said foldable sheet having, after die cutting, longitudinal and transverse directions, a left working edge, a right working edge, an upper edge, a lower edge, a front and a back;
b) folding said foldable sheet in a manner selected from the group consisting of i) first folding the sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips, each strip having substantially the same transverse width, to form a transversely folded sheet, and then folding the transversely folded sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form a folded sheet with an odd number of panels; and ii) first folding the sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form transverse strips, each strip having substantially the same longitudinal width, to form a longitudinally folded sheet, and then folding the longitudinally folded sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form a folded sheet with an odd number of panels;
said sheet having a tab for manually gripping an edge of the sheet when folded, said tab being attached to a corner panel, said corner panel being on the outside of the sheet when folded about the longitudinal and transverse fold lines.
In one embodiment, the tab is part of the foldable sheet when cut from the larger sheet.
In another embodiment, the foldable sheet has an extension attached to the sheet at least on one location selected from i)the upper edge, ii) the lower edge; iii) the left working edge and iv) the right working edge, with the proviso that when attached to the right working edge, the extension is separated from the tab, and such extension is folded inwardly into the folded sheet.

In another embodiment, a corner panel adjacently opposite the tab corner has an integral extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet, said extension being folded and glued prior to the foldable sheet being folded in concertina fashion.
Brief Description of the Drawings Figure 1 is a representation of an unfolded sheet of the present invention, showing fold lines.
Figure 2 shows the sheet of Figure 1 folded about longitudinal fold lines.
Figure 3 is a representation of another unfolded sheet of the present fold lines.
Figure 4 is a representation of an unfolded sheet of the present invention, with an extension which may be folded and glued to a corner panel of the sheet.
Detailed Description of Preferred Embodiments Figure 1 shows an unfolded sheet 10 with a right working edge 11, a left working edge 12, an upper edge 13 and a lower edge 14. Sheet 10 has longitudinal fold liens 15-20 equidistantly spaced between left working edge 11 and right working edge 11. Longitudinal fold lines 15-20 divide sheet 10 with an even number of longitudinal strips 21-27. Sheet 10 also has transverse fold lines 28 and 29 equidistantly spaced between upper edge 13 and lower edge 14. Transverse fold lines 28 and 29 divide the sheet 10 into an odd number transverse strips (not numbered). The fold lines cause the formation of an odd number of panels, including adjacently opposed corner panels 31 and 32.
The panels adjacent longitudinal fold lines 16, 18 and 20 fold towards one another so that the front faces of the panels are together when folded. The panels adjacent longitudinal fold lines 15, 17 and 19 fold towards one another so that the back faces of the panels are together. Thus the sheet is folded in concertina fashion about the longitudinal folds, as seen in Figure 2.
After the sheet has been folded about the longitudinal folds 15-20, the sheet can be folded about transverse folds 28 and 29 (Figure 2), so that the front faces of the panels adjacent fold line 28 (between left working edge 12 and fold line 15) are together, and the back faces of the panels adjacent fold lines 29 (between right working edge 11 and fold line 20) are together.
In another embodiment, a corner panel adjacently opposite the tab corner has an extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet.
In a further embodiment, a corner panel which is adjacent to the tab has an extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet.
In yet another embodiment, the sheet and any extensions are die cut, as a single piece, from a larger sheet.
The invention also provides a process for making a folded sheet comprising:
a) cutting a foldable sheet from a larger sheet, said foldable sheet having, after die cutting, longitudinal and transverse directions, a left working edge, a right working edge, an upper edge, a lower edge, a front and a back;
b) folding said foldable sheet in a manner selected from the group consisting of i) first folding the sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips, each strip having substantially the same transverse width, to form a transversely folded sheet, and then folding the transversely folded sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form a folded sheet with an odd number of panels; and ii) first folding the sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form transverse strips, each strip having substantially the same longitudinal width, to form a longitudinally folded sheet, and then folding the longitudinally folded sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form a folded sheet with an odd number of panels;
said sheet having a tab for manually gripping an edge of the sheet when folded, said tab being attached to a corner panel, said corner panel being on the outside of the sheet when folded about the longitudinal and transverse fold lines.
In one embodiment, the tab is part of the foldable sheet when cut from the larger sheet.
In another embodiment, the foldable sheet has an extension attached to the sheet at least on one location selected from i)the upper edge, ii) the lower edge; iii) the left working edge and iv) the right working edge, with the proviso that when attached to the right working edge, the extension is separated from the tab, and such extension is folded inwardly into the folded sheet.
In yet another embodiment, the extension is attached to the sheet at an edge, wherein the edge is perforated and forms a fold line, and the extension is folded inwardly into the folded sheet, about the perforated fold line.
In another embodiment, a corner panel adjacently opposite the tab corner has an integral extension which can be folded over the corner panel and glued thereto to form a stiff cover for the folded sheet, said extension being folded and glued prior to the foldable sheet being folded in concertina fashion.
Brief Description of the Drawings Figure 1 is a representation of an unfolded sheet of the present invention, showing fold lines.
Figure 2 shows the sheet of Figure 1 folded about longitudinal fold lines.
Figure 3 is a representation of another unfolded sheet of the present fold lines.
Figure 4 is a representation of an unfolded sheet of the present invention, with an extension which may be folded and glued to a corner panel of the sheet.
Detailed Description of Preferred Embodiments Figure 1 shows an unfolded sheet 10 with a right working edge 11, a left working edge 12, an upper edge 13 and a lower edge 14. Sheet 10 has longitudinal fold liens 15-20 equidistantly spaced between left working edge 11 and right working edge 11. Longitudinal fold lines 15-20 divide sheet 10 with an even number of longitudinal strips 21-27. Sheet 10 also has transverse fold lines 28 and 29 equidistantly spaced between upper edge 13 and lower edge 14. Transverse fold lines 28 and 29 divide the sheet 10 into an odd number transverse strips (not numbered). The fold lines cause the formation of an odd number of panels, including adjacently opposed corner panels 31 and 32.
The panels adjacent longitudinal fold lines 16, 18 and 20 fold towards one another so that the front faces of the panels are together when folded. The panels adjacent longitudinal fold lines 15, 17 and 19 fold towards one another so that the back faces of the panels are together. Thus the sheet is folded in concertina fashion about the longitudinal folds, as seen in Figure 2.
After the sheet has been folded about the longitudinal folds 15-20, the sheet can be folded about transverse folds 28 and 29 (Figure 2), so that the front faces of the panels adjacent fold line 28 (between left working edge 12 and fold line 15) are together, and the back faces of the panels adjacent fold lines 29 (between right working edge 11 and fold line 20) are together.
Thus, the back of panel 31, which has tab 30 attached thereto is on the outside of the folded sheet, and the front of panel 32 is also on the outside of the folded sheet.
In the embodiment shown in Figures 1 and 2 there is a printed "button" 33. The purpose of button 33 and tab 30 is to provide a visual cue for a person wishing to open the folded sheet to grasp panel 32 at button 33 and grasp tab 30 and pull the sheet apart diagonally. By so pulling, the sheet is unfolded in an easy manner, so that printed messages, graphics, catalogues and the like can be read on the front and/or back of the sheet.
Instead of first folding sheet 10 about longitudinal fold lines 15-20, and then folding the sheet about transverse fold likes 28 and 29, the transverse fold lines 28 and 29 may be folded first and then the sheet may be further folded about the longitudinal fold lines 15-20.
Although Figure 1 shows six longitudinal fold lines, any number of longitudinal lines may be used provided they are of even number. Also, any number of transverse fold lines may be used provided they are of even number.
Figure 3 shows a modified version of the sheet of Figure 1. In essence the sheet has tear-off tickets at the right and left working edges. Sheet 40 has a right working edge 41, a left working edge 42, an upper edge 43 and a lower edge 44. Sheet 40 has longitudinal fold lines 45-50 and transverse fold lines 51 and 52. Corner panel 59 has tab 53 attached thereto. Attached to sheet about a perforated fold line at left working edge 42 is extension 56. Fold lines 51 and 52, within extension 56, are also perforated. In this embodiment, extension 56 comprises three tear-off tickets. A similar tear-off 35 extension 54 is attached to sheet 40 about a perforated fold line at right working edge 41. Extension 54 is separated from tab 53 at a cut 55. Extensions 54 and 56 may be folded about perforated edges 41 and 42 respectively so that when sheet 40 is folded, extensions 54 and 56 are tucked inside the folded sheet.
In Figure 3, there is an extension 57 attached to upper edge 43. Extension 57 is foldable about fold line 58, which is part of upper edge 43, Extension 57 may be a "pop-up" design, which pops up when the folded sheet is unfolded.
Figure 4 shows a sheet 60 with left and right working edges 61 and 62 respectively, tab 63 and corner panel 64. Attached to corner panel 63 is an extension 65 which is foldable about fold line 68, which is part of left working edge 61. Extension 65 has glue tabs 66 and 67. Glue tabs 66 and 67 may be folded so that when extension 65 is folded about fold line 68 and glue is applied to the glue tabs, panel 64 is essentially doubled in thickness, thus providing extra stiffness to panels 64. Folding and gluing extension 65 in such a manner also provides a pocket on the front outside panel.
The sheet of the present invention may be printed using conventional offset or web printing technologies.
In short print runs, e.g. up to about 50 000 sheets, a conventional offset press appears to be most economical.
For larger runs, it appears to be more economical to use a continuous web press. After printing, a two-side printed sheet is obtained.
After printing, the oversized sheets are die cut to the finished size and shape, with the pull tab adjacent a corner of the cut sheet. The paper grade, thickness and size of the sheet is a function of the size and compactness of the desired folded sheet.
If the sheet has extensions as an integral part of _ g _ the sheet, the extensions are ~~hit" with a blunt crease die to introduce fold lines, and the folding and gluing process may be done manually or by specially designed machinery. If there are no folded and glued extensions, or if extension have been folded and glued, the die cut sheet are folded automatically on a so-called buckle folder, which has been modified to produce a consistent Z-fold or concertina fold without introducing compound creep or skewing.
After the product has been fully folded, it has a front and back panel. One of these panels has the tab attached thereto. If the tab is on the back panel, when the tab is grasped in one hand and the front panel is grasped with the other hand, the folded sheet can be unfolded merely by pulling the hands apart in a direction which is parallel to the free corners of the front and back panels. In so doing, the unfolded sheet reveals printed material on the front and back of the unfolded sheet.
Typically, the panels are the size of a credit card or similar, so that the folded sheet easily fits in a wallet or purse. The panels may be larger, for example if a large map is to be produced.
The present invention may be used whenever information or instruction is required to be retained ready for quick reference. The folded sheet provides many time the surface area of the panels of the fully folded sheet and can easily be store in a pocket or purse. The free-form poster layout of the sheet is more flexible for information assembly and graphical reference than is a stapled booklet of equal size, where the content is restricted by the individual page formats.
It will be understood that the invention has many uses. For example, the front and back panels of the _ g _ folded sheet may be reserved for special advertising material, e.g. a special offer, corporate identity information. The sheet may provide a large amount of information, e.g. benefits and side effects of 5 medications, operating instructions for pesticides, electronic equipment, telephone and other listings.
As will be understood, modifications may be made without departing from the spirit of the invention.
In the embodiment shown in Figures 1 and 2 there is a printed "button" 33. The purpose of button 33 and tab 30 is to provide a visual cue for a person wishing to open the folded sheet to grasp panel 32 at button 33 and grasp tab 30 and pull the sheet apart diagonally. By so pulling, the sheet is unfolded in an easy manner, so that printed messages, graphics, catalogues and the like can be read on the front and/or back of the sheet.
Instead of first folding sheet 10 about longitudinal fold lines 15-20, and then folding the sheet about transverse fold likes 28 and 29, the transverse fold lines 28 and 29 may be folded first and then the sheet may be further folded about the longitudinal fold lines 15-20.
Although Figure 1 shows six longitudinal fold lines, any number of longitudinal lines may be used provided they are of even number. Also, any number of transverse fold lines may be used provided they are of even number.
Figure 3 shows a modified version of the sheet of Figure 1. In essence the sheet has tear-off tickets at the right and left working edges. Sheet 40 has a right working edge 41, a left working edge 42, an upper edge 43 and a lower edge 44. Sheet 40 has longitudinal fold lines 45-50 and transverse fold lines 51 and 52. Corner panel 59 has tab 53 attached thereto. Attached to sheet about a perforated fold line at left working edge 42 is extension 56. Fold lines 51 and 52, within extension 56, are also perforated. In this embodiment, extension 56 comprises three tear-off tickets. A similar tear-off 35 extension 54 is attached to sheet 40 about a perforated fold line at right working edge 41. Extension 54 is separated from tab 53 at a cut 55. Extensions 54 and 56 may be folded about perforated edges 41 and 42 respectively so that when sheet 40 is folded, extensions 54 and 56 are tucked inside the folded sheet.
In Figure 3, there is an extension 57 attached to upper edge 43. Extension 57 is foldable about fold line 58, which is part of upper edge 43, Extension 57 may be a "pop-up" design, which pops up when the folded sheet is unfolded.
Figure 4 shows a sheet 60 with left and right working edges 61 and 62 respectively, tab 63 and corner panel 64. Attached to corner panel 63 is an extension 65 which is foldable about fold line 68, which is part of left working edge 61. Extension 65 has glue tabs 66 and 67. Glue tabs 66 and 67 may be folded so that when extension 65 is folded about fold line 68 and glue is applied to the glue tabs, panel 64 is essentially doubled in thickness, thus providing extra stiffness to panels 64. Folding and gluing extension 65 in such a manner also provides a pocket on the front outside panel.
The sheet of the present invention may be printed using conventional offset or web printing technologies.
In short print runs, e.g. up to about 50 000 sheets, a conventional offset press appears to be most economical.
For larger runs, it appears to be more economical to use a continuous web press. After printing, a two-side printed sheet is obtained.
After printing, the oversized sheets are die cut to the finished size and shape, with the pull tab adjacent a corner of the cut sheet. The paper grade, thickness and size of the sheet is a function of the size and compactness of the desired folded sheet.

b) folding said foldable sheet in a manner selected from the group consisting of i) first folding the sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form longitudinal strips, each strip having substantially the same transverse width, to form a transversely folded sheet, and then folding the transversely folded sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form a folded sheet with an odd number of panels; and ii) first folding the sheet in concertina fashion about an even number of transverse fold lines between the upper and lower edges, to form transverse strips, each strip having substantially the same longitudinal width, to form a longitudinally folded sheet, and then folding the longitudinally folded sheet in concertina fashion about an even number of longitudinal fold lines between the right and left working edges, to form a folded sheet with an odd number of panels;
said sheet having a tab for manually gripping an edge of the sheet when folded, said tab being attached to a corner panel, said corner panel being on the outside of the sheet when folded about the longitudinal and transverse fold lines.
