Method and apparatus for producing sheet-like printed products having a folded portion

A method and apparatus are disclosed for forming printed paper products having a folded or pocket portion, for example inserts for magazines and brochures having a reply envelope. A moving web of paper from which the inserts are made is first folded along the edges thereof to form the folded or envelope portion of the insert. Thereafter, printing is carried out on the folded web. Since folding precedes printing, a web having a width which exceeds the maximum width that the printing press can accommodate may be used. In this way, an insert having a width up to the maximum width that the printing press can accommodate and/or inserts having envelope portions and/or envelope flap portions of increased size are obtained.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to the forming and printing of paper products 
having a folded flap, pocket, envelope or the like portion, particularly 
paper products made from a moving web of paper in which the opposed edges 
of the moving web are continually folded inwardly to form envelopes. 
2. Description of the Prior Art 
In known systems for forming and printing sheet-like paper products having 
a folded flap, pocket, envelope or the like portion, printing is applied 
to either or both sides of the unfolded stock or web as it is advanced and 
thereafter the stock or web is glued and the opposed edges thereof are 
folded inwardly into the desired form. As a result of folding the opposed 
edges inwardly the folded finished product has a width which is less than 
the maximum width of web which the printing apparatus can accommodate. 
In the forming and printing of inserts for magazines, advertising 
brochures, etc. which include envelopes that may be used, for example, as 
reply envelopes for ordering merchandise, subscribing, etc., printing is 
carried out on an unfolded moving web of paper. Thereafter, the web of 
paper is glued and folded to form an insert having an envelope at each 
end. Each envelope includes a rear flap which extends over a substantial 
portion of the rear of the envelope when it is sealed. 
Presses such as roll-fed offset printing presses currently being used for 
printing inserts of this type are limited with respect to the maximum 
width of the web of paper which can be handled. For example, a commonly 
used commercial offset press is limited to webs of approximately 173/4 
inches maximum width. Printing, scoring, slitting, gluing, etc. are all 
carried out on the full width of the web prior to folding the opposed 
edges of the moving web by means of guides known as plows. Upon folding 
the web to form envelopes, the width of the finished insert is reduced to 
a width of substantially less than 173/4 inches. Thus, with a limit of 
173/4 inches for the width of the web which can be printed on, the size of 
the resulting envelopes and/or the rear flaps of the envelopes, as well as 
the overall width of the finished insert are limited. 
In order to provide larger envelopes, for example to satisfy postal 
regulations, it is necessary to reduce the size of the rear flap while 
retaining the same overall maximum size of the unfolded stock or web 
supplied to the printing apparatus. It has not heretofore been possible to 
provide an insert having an overall width which exceeds the width that the 
printing apparatus can accommodate. 
Although U.S. Pat. Nos. 3,899,381 and 4,066,251 disclose printed products, 
neither relates to a paper product or insert of the type described above. 
U.S. Pat. No. 3,899,381, issued on Aug. 12, 1975, relates to the 
production of direct-mail advertising booklets from a continuous web of 
superposed paper-like strips or sheets. U.S. Pat. No. 4,066,251, issued on 
Jan. 3, 1978, relates to the production of combination mailing envelopes 
and return envelopes from a plurality of continuous webs of sheet 
material; one of the webs is folded to form a front panel of the mailing 
envelope and a back panel common to the mailing envelope and the return 
envelope. 
SUMMARY OF THE INVENTION 
It is an object of the present invention to manufacture printed paper 
products having a folded flap, pocket, envelope or the like portion in 
which the product and/or the folded portion may be of a size greater than 
the maximum size which can be produced from the widest web which can 
normally be employed. 
It is also an object of the present invention to manufacture printed paper 
products having a folded flap, pocket, envelope or the like portion which 
may be of a size greatr than that which can be produced from the widest 
web which can normally be employed. 
It is another object of the present invention to manufacture a printed 
insert having an envelope portion and a back flap portion for the envelope 
portion in which the insert, the envelope portion and/or the back flap 
portion may be of increased size. 
It is still another object of the present invention to manufacture such 
printed paper products and inserts from a continually moving web of paper 
stock. 
It is still another object of the present invention to provide a method and 
apparatus for producing such printed paper products and inserts. 
It is also an object of the present invention to print on one or both sides 
of a continually moving web of paper having folded or pocket portions at 
each end. 
In accordance with the present invention, folding of a web of paper stock 
is carried out by plows in advance of printing and the printing is applied 
while the stock is folded. Thus, the web of paper stock is first folded to 
the desired size which can be equal to the maximum size which the printing 
apparatus is adapted to receive and thereafter printing is applied to the 
folded stock. As a result, a larger size stock may be used to provide a 
printed product of increased size and/or to provide a product having 
folded portions or pockets which may be of increased size. The width of 
the stock fed to prior art apparatus can thereby be increased to exceed a 
predetermined maximum size while utilizing printing apparatus capable of 
accommodating up to the predetermined maximum size. 
In accordance with the invention, apparatus such as a plow is provided to 
fold a web of paper stock before it enters the printing press. The feeding 
of a folded web to a printing press which is adapted to accommodate 
conventional width stock, i.e. stock up to the predetermined maximum size, 
enables the size of the folded portion, i.e. the flap, pocket or envelope, 
to be increased, and in the case of an insert comprising an envelope 
thereon, the envelope can be increased without the need for decreasing the 
size of the rear flap of the envelope. 
Printed sheet paper products which include a folded portion at an end of 
the product are produced in accordance with the invention. The apparatus 
and method of the invention are conditioned to operate in conjunction with 
a printing press, the printing press in a direction transverse to the line 
of travel of paper stock through the printing press having a predetermined 
maximum dimension which fixes the maximum width of paper stock that can be 
printed. In accordance with the invention, at least one edge portion of 
paper stock having a width greater than the predetermined dimension of the 
printing press is folded along a fold line to provide folded paper stock 
of a width which is less than the predetermined dimension of the printing 
press and the folded paper stock is advanced to the printing press for 
printing while the paper stock is folded. 
Adhesive may be applied to the paper stock at a predetermined location 
thereon which is contiguous with the edge portion after the folding 
thereof to secure the folded edge portion to the paper stock. The adhesive 
may be applied in the form of strips extending spaced apart with respect 
to one another and transversely with respect to the line of travel of the 
paper stock through the press, the strips of adhesive being adapted to 
secure the folded edge portion at each of the oppositely disposed ends of 
the printed sheet paper product. 
In the disclosed embodiment, the apparatus and method are conditioned to 
operate in conjunction with an offset printing press having at least one 
printing unit including a plate cylinder, a blanket cylinder in rolling 
relation therewith, and an impression cylinder extending adjacent to the 
blanket cylinder and forming a nip therewith, or an offset perfecting 
press including upper and lower plate and blanket cylinders, the blanket 
cylinders being adjacently disposed to form a nip therebetween, the 
printing press in a direction transverse to the line of travel of paper 
stock through the printing press having a predetermined maximum dimension 
which fixes the maximum width of paper stock than can be printed when the 
paper stock is advanced through the nip. 
In accordance with one aspect of the invention, the edge portion of the 
paper stock is folded to a position contiguous with a portion of the 
surface of the paper stock thereby presenting a folded portion of double 
thickness of paper stock and an unfolded portion of single thickness of 
paper stock to be printed on, the invention providing for uniformly 
increasing the diameter of the impression roller as determined 
substantially by the caliper of the paper stock to enable the unfolded 
portion of the paper stock and the folded portion of the paper stock to be 
contiguous with the blanket cylinder simultaneously when the paper stock 
is advanced through the nip of the blanket cylinder and the impression 
cylinder for printing. In accordance with the disclosed embodiment of the 
invention, the diameter of the cylinder may be increased by a shim plate. 
In the case of a perfecting press, the surface of the blanket cylinder in 
contact with the folded side of the paper is modified to provide a 
printing surface which uniformly contacts the folded paper product when 
the paper is advanced through the nip of the blanket cylinders. In 
accordance with a disclosed embodiment, the diameter of the blanket 
cylinder may be increased by a shim disposed between the blanket cylinder 
mat surface and the cylinder core. 
In the disclosed embodiments, means are provided for delivering a moving 
web of paper stock from a supply thereof to means for folding at least one 
edge portion of the paper stock. The means for delivering a moving web of 
paper stock comprise means in rolling engagement with the web of paper 
stock for delivering the web of paper stock from a supply roll thereof to 
the folding means. The means for folding at least one edge portion of 
paper stock comprises a plow member disposed contiguous with the surface 
of the moving web of paper stock, the outer portion of the plow member 
with respect to the central portion of the moving web being adjacent to 
the location on the moving web of the fold line, the means for advancing 
the folded paper stock being disposed downstream of the plow member and 
advancing the edge portion of the moving web transversely with respect to 
the central portion of the moving web commencing at the outer portion of 
the plow member. The means for advancing the folded paper stock comprises 
at least one roller rotating in engagement with the folded paper stock. 
In accordance with one aspect of the invention, a method is provided for 
continuously producing printed sheet-like paper products each of which 
includes a folded flap, pocket, envelope or the like portion at each end 
of the product by utilizing printing apparatus which is adapted to print 
on a web of paper stock of a predetermined maximum width. The method 
comprises the steps of providing a web of paper stock having a width which 
exceeds the normal predetermined maximum width which the printing press 
can accommodate, folding the edge portions of the web of paper to provide 
a web of folded paper stock having a width equal to or less than the 
predetermined width, and printing on selected portions of the folded web 
of paper stock. The paper stock is advantageously an endless web of paper, 
and the folded and printed paper stock is severed into individual 
products. 
The folded and printed stock may be scored and perforated prior to slitting 
if desired. An adhesive may be applied to secure the folded portions and 
an adhesive may be applied for sealing the flap portion to the envelope 
portion when the envelope is used. 
Additionally, edge portions of the sheet stock may be scored and slit prior 
to applying adhesive and folding. Printing may be carried out on selected 
portions of both sides of the folded paper stock and the folded paper 
stock may be turned over after printing on one side and before printing on 
the other side. 
Apparatus according to another aspect of the invention is provided for 
continuously producing printed sheet-like products each of which includes 
a folded flap, pocket, envelope or the like portion. The apparatus 
comprises means for printing on stock of a width of up to a predetermined 
maximum width, means for folding the excess width paper stock to provide 
paper stock of a width equal to or less than the predetermined width 
including the folded portion, and means for printing on the folded paper 
stock. The means for printing is positioned to receive the folded paper 
stock of a width up to the predetermined width and thus may be a 
substantially conventional means for printing, if desired. 
More particularly, the means for printing may comprise a modified 
conventional press (modified in accordance with the invention) which 
receives and prints on a paper web of approximately 173/4 inches maximum 
width. According to one embodiment of the invention, apparatus such as 
plows for plow-folding the web are located ahead of the press and the 
folded web which is fed to the press, rather than the unfolded web, can be 
up to the 173/4 inches maximum width. Thus, in accordance with the 
invention, a web having a width such as 24 inches, for example, is 
supplied to the folding apparatus of the invention which is positioned in 
advance of the press apparatus. In the apparatus of the invention, the 24 
inch web is scored, slit, and adhesive (for securing the folded portions) 
is applied thereto, and then the web is plow-folded into the desired width 
of up to 173/4 inches for feeding to the press apparatus. Thereafter, 
printing, scoring and the application of the adhesive (for sealing the 
flap when the envelope is used) are applied to the plow folded web. Since 
the inside surfaces of the folded parts of the sheet do not receive 
printing, pre-folding in accordance with the invention does not reduce the 
surface area available for printing. 
These and other aspects of the invention will be more apparent from the 
following description of the preferred embodiments thereof when considered 
with the accompanying drawings and appended claims.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS 
In the prior art offset press system illustrated by the block diagram of 
FIG. 1, a web of paper of a predetermined maximum width, such as 
approximately 173/4 inches for example, is supplied to the system 20 which 
forms printed envelope assemblies 22 from the web such as inserts 22 for 
magazines, advertising, brochures, etc., one of which is illustrated in 
FIG. 12. The inserts 22 each include a folded envelope or pocket portion 
24 formed at each edge of the insert and envelope flap portions 26 which 
extend between the envelope portions 24. Perforated lines 28 are provided 
in the central portion of the insert in order that the insert may be 
separated into individual envelopes. Glue strips 30 are applied adjacent 
to the perforated lines 28 in order that rear flap portion 26 can be 
secured to the envelope portion to seal the envelope when it is ultimately 
used. 
A web of paper of a predetermined maximum width (approximately 173/4 
inches, for example) is first fed into the offset press system 20 of FIG. 
1 to the printing apparatus or press of the system. Printing is carried 
out on one side, for example the bottom side, of the web of paper, as 
referenced by step 30. Conventional offset printing presses can 
acccommodate webs of paper of various widths to a predetermined maximum 
width. Therefore the printing press construction limits the maximum size 
of the insert which can be produced. The maximum size of the insert in 
turn limits the size of the envelope portion 24 and/or the back flap 
portion 26 of the insert. 
The web is continuously fed into the offset press system 20 and printing is 
carried out (step 30) on a first side of the moving web in its flat, 
unfolded configuration. Thereafter, printing is carried out (step 32) on 
the other, for example the top, side. The system 20 may include apparatus 
for turning over the moving web of paper in order that printing is carried 
out from a single location above or below the web. In addition printing 
presses may be utilized to alternately print on opposite sides of the 
moving web of paper without turning the web over. If printing is desired 
in more than one color, the moving web of paper is advanced through a 
printing station for each side for each color desired. 
After printing, the edges of the printed web of paper are slit and the web 
scored to provide score lines (score lines 31 in FIG. 12) between 
perforation lines in the central part of the envelope back flap portions 
and adjacent to the inner edge of each envelope portion to facilitate 
folding of the insert and folding of the flap portions when sealing 
individual envelopes, respectively. Perforating is also done at this time 
to provide the perforation lines 28 in order that the finished insert may 
be separated into individual envelopes. Slitting, scoring and forming the 
perforations is referenced by step 34 in FIG. 1. Next glue strips (strips 
28 in FIG. 12) are applied adjacent to the perforated lines and glue lines 
(lines 52 in FIGS. 3, 5 and 9-11) are applied transversely to the edges. 
The glue strips are for securing the edges of the flaps when it is desired 
to seal the envelopes and for example may be a fast drying glue or a dry 
glue which is activated by the application of moisture. The application of 
the glues to the printed web is referenced by step 36. If desired, glue 
may be applied (step 36) first and the web slit and scored (step 34) 
thereafter. The edges of the web are next plow-folded upwardly (step 38) 
and the plow-folded edges are rolled down (step 40) to join the edges 
along the glue lines 52. A web product such as the web illustrated in FIG. 
11 is obtained at this point. The glue lines 52 are of a sufficient width 
to permit a single glue line to be used to join the folded web in adjacent 
inserts when the web is cut off through the glue lines. 
If desired, the web may again be plow-folded (step 42) along the central 
score line 31 to form a folded insert. The web is next cut off (step 44) 
to form the individual inserts illustrated in FIG. 12. 
Thus the system 20 of FIG. 1 can provide inserts having envelope portions 
and flap portions of a limited size utilizing a web of paper of a given 
width corresponding to the maximum width which the printing apparatus can 
accommodate. Any increase in the size of the envelope portion results in a 
decrease in the size of the flap portion and vice-versa. 
It is desirable to have the flap portion overlap the entire rear of the 
envelope portion so that, for example, different printed matter can be 
applied to the rear of the envelope portion and to the flap portion. In 
this way, the printed matter on the rear of the envelope portion and on 
the flap portion may be independent of each other. This has not heretofore 
been possible when increasing the size of the envelope portion to satisfy 
postal regulations. 
In accordance with the invention, a web of paper can be supplied to the 
system 50 having a width which exceeds the maximum width which the 
printing apparatus can ordinarily accommodate. The web is plow-folded and 
the envelope portions formed before printing so that an insert having a 
final width which is up to the maximum width that the printing apparatus 
can accommodate is obtained. Thus, the web is folded ahead of the printing 
apparatus and the folded web is printed on. According to the invention, an 
insert which may be larger than the finished insert produced by the offset 
press system 20 and/or an insert which has larger envelope and/or larger 
flap portions can be obtained. 
In the system 50 of FIG. 2, according to the invention, a web of paper 
which is wider than the maximum width which the printing apparatus can 
accommodate is delivered to the system. For example, a web of paper of a 
24 inch width is supplied to the system 50 in which the press is adapted 
to receive a web no greater in width than about 173/4 inches. Prior to 
printing, glue lines are applied adjacent to the edge portions of the 
moving web of paper in transversely extending lines 52 (FIG. 5). The edge 
portions bearing the glue lines are then plow-folded upwardly. The glue 
applying and plow-folding steps are referenced by steps 54 and 56, 
respectively, in FIG. 2. Thereafter, the plow-folded and glued edges are 
press-rolled (step 58) to join the glued edges and form the envelope 
portions. If desired, adjacent edge portions of the web may be scored and 
slit (step 60) to trim the web of paper prior to the application of the 
glue lines 52. A kit or attachment as shown for example in FIG. 13 and 
described below may be provided in accordance with the invention which 
includes apparatus to carry out the foregoing steps. 
The moving web of paper with the plow-folded envelope portions is fed to an 
offset printing press referenced as step 62. The moving web of paper is 
first printed on one side (step 64), for example the flap side, while 
folded. The moving web of paper is thereafter turned over (step 66) and 
printing is carried out on the reverse side (step 68), again while the 
moving web of paper is folded. FIG. 9 illustrates the web of paper after 
printing is carried out on the flap side and FIG. 10 illustrates the web 
of paper after printing is carried out on the reverse side. 
The printed and folded web of paper is next scored and the perforations 
formed (step 70). As illustrated in FIG. 11, score lines 31 are formed 
along the center of the web and adjacent envelope portions 24, and 
perforated lines 28 are formed adjacent to the central score line on both 
sides thereof. As mentioned, the score lines 31 facilitate folding the web 
along the central score line and the folding of the flap portions onto the 
envelope portions in the finished insert (FIG. 12). The insert may be 
separated along the perforated lines to form two envelopes. The central 
score line may be slit in order to provide to two separate envelopes 
instead of folding along that score line. 
Glue (fast drying or dry glue, for example) is next applied (step 72) along 
strips 30 adjacent to the perforated lines and thereafter the web is cut 
off to form the individual inserts shown in FIG. 12. Alternatively, glue 
may be applied (step 72) first and the web slit and scored (slip 70) 
thereafter. If desired, the web may be again plow-folded (step 76) to form 
a folded insert prior to cutting off. 
Referring more particularly now to FIGS. 3-5, the larger width web of paper 
80 for example, a 24 inch web of paper, is fed to the system via drive and 
tension rollers 82. If desired, the edge portions 83 of the web of paper 
are scored and slit (FIG. 2, step 60) and thereafter glue is applied in 
conventional fashion in transversely-extending lines 52 progressing 
inwardly from the edges of the web. Plow-folders 84 are located after the 
glue applying station (step 54) and act to fold the edges of the moving 
web upwardly. The plow shoes 86 contact the moving web of paper inwardly 
of the glue lines 52 with the respective outside edges 88 of the plow 
shoes forming the fold line, the position of the shoe thereby determining 
the width of the folded edge of the web of paper and correspondingly the 
width of the envelope portions 24. 
As shown in FIG. 6, the edges 89 of the web of paper are folded upwardly 
along the outside edges 88 of the plow shoes 86. The moving web of paper 
progresses towards opposed press rollers 90 (or S-loop press rollers 90A 
in FIG. 13) which act to press the edges of the web of paper having the 
glue lines 52 thereon against interior portions of the web to join the 
folded edges of the web as shown in FIG. 7. 
The folded web is then advanced to the printing apparatus 60A (FIG. 3) and 
the flap side of the web is printed first. It may be necessary, depending 
upon the thickness of material and nature of printing, to compensate for 
the double thickness of paper at the folded portions during printing. For 
example, it may be possible to see a break in printing at the transition 
from single to double thickness, particularly where a color is printed 
across the transition. In order to deliver the web as a flat surface to 
the blanket cylinder 92 of the printing apparatus, a shim 91 (FIG. 8) may 
be wrapped around and secured to the circumference of impression cylinder 
93. The plate cylinder is referenced by 97. The width of the shim 91 
substantially corresponds to the space between the folded side portions. 
Thus the shim 91 positions the central portion of the web into the plane 
of the folded portions during passage beneath the blanket 92 for printing. 
After printing on the flap side, the folded web of paper (FIG. 9) is 
supplied to the turn-over apparatus 94 (FIG. 4) which comprises a series 
of rollers 95. However, other turn-over apparatus known in the art may be 
used in place of apparatus 94. The web of paper enters the turn-over 
apparatus 94 with the flap side (side A) up and leaves the turn-over 
apparatus 94 with the flap side (side A) down. The turned-over web is now 
fed to another stage of the printing apparatus 60C and the reverse side 
(side B) is printed. A shim similar to the shim 91 shown in FIG. 8 may be 
secured to the impression cylinder in order that the central portion of 
the web is even with the blanket during printing. The web with printing on 
both sides is illustrated in FIG. 10. If printing of multiple colors is 
desired, the moving web is delivered to additional printing stations for 
each side and for each color desired. For example, if printing of two 
colors is desired on each side, the web is fed through two printing 
presses, then the web is turned over and then the web is fed through two 
more printing presses. As illustrated in FIG. 3 printing on side A is 
applied in one color by press 60A and in another color by press 60B. The 
web is turned over by rollers 95 and printing is applied in two colors on 
side B by presses 60C and 60D. 
Printing may also be carried out simultaneously on both sides of the moving 
web. As illustrated in FIG. 13, an offset perfecting press 100 may be 
utilized to simultaneously print on both sides of the web. Additional 
perfecting presses 100A may be provided for different colors to be 
printed. The perfecting press 100 includes opposed sets of plate 102 and 
blanket 104 cylinders. Each blanket cylinder utilizes the blanket cylinder 
on the opposed side of the web as an impression cylinder. Again, it may be 
necessary to compensate for the double thickness of paper at the folded 
portions during printing. In order to deliver the web as a flat surface to 
the blanket cylinders 104 of the perfecting printing press, the diameter 
of the blanket cylinder on the double thickness side of the web is 
increased in the region between the folded portions (FIG. 14). The width 
of the increased diameter portion substantially corresponds to the space 
between the folded side portions. Thus, the mat surface 105 of the upper 
blanket cylinder will uniformly contact the web surface. For example, a 
shim 106 may be placed between the blanket cylinder core and the mat 
surface of the blanket cylinder to enlarge the diameter of the overall 
cylinder in the central region thereof. 
After printing has been carried out on one or both sides of the moving web, 
the web is scored, the perforations are formed, the glue strips are 
applied and the web is cut-off as described above. 
The printed folded web shown in FIGS. 9-12 has a maximum width of 173/4 
inches as opposed to the unfolded maximum width web of 173/4 inches which 
is printed on in the prior art systems. In accordance with the invention, 
a web, wider approximately 24 inches in width for example, is supplied to 
the system as compared to a web of 173/4 inches for prior art systems. 
Thus, up to 61/4 inches of web are available over prior art systems to 
increase the size of the insert and/or the size of the envelope and/or 
back flap portions. 
The apparatus used to carry out the glue applying, folding, rolling and 
scoring and slitting (optional) steps (54, 56, 58 and 60, respectively, 
illustrated in FIG. 2) can be supplied as a kit or attachment in 
accordance with one aspect of the invention. Such a kit 107 is illustrated 
in FIG. 13 and includes apparatus 108 for applying the glue lines 52 and 
the plow folder 84. The kit may also include the scoring and slitting 
apparatus 110, if desired. The kit 106 receives paper web having a width 
wider that can be accommodated by the printing apparatus, for example, 
approximately 24 inches. The larger width web is plow folded by the kit to 
a width which can be accommodated by the printing apparatus, for example, 
approximately 173/4 inches. Thus, the apparatus downstream of the kit 107 
accommodates web having a width no larger than a width which conventional 
apparatus can accommodate. 
The apparatus used to carry-out the printing, turn-over (when not utilizing 
a perfecting press), scoring and perforating, glue applying, plow folding 
and slitting steps (64, 66, 68, 70, 72, 74 and 76, respectively, 
illustrated in FIG. 2) can be conventional with the printing presses 
modified in accordance with the invention. Thus, existing apparatus 
(modified as taught herein) possessed by a manufacturer can be utilized to 
carry out certain steps of the manufacture, and a kit 107 may be provided 
to be disposed ahead of the existing, modified apparatus. As a result, new 
postal regulations requiring larger envelopes can be satisfied using the 
invention herein and existing equipment to manufacture the inserts. 
While the invention has been described in connection with printing 
apparatus capable of accommodating a web width of up to approximately 
173/4 inches and a larger web of approximately 24 inches width which, in 
accordance with the invention, is folded to up to the 173/4 inch width 
prior to printing, such widths have been chosen for purposes of 
illustration and are merely examples it is not intended that the invention 
be limited by such exemplary widths. Additionally, while in preferred 
embodiments, glue has been applied in glue lines 52 for securing the 
folded portion of the web to the remainder of the web, it is understood 
that a product can be made in accordance with the invention in which the 
folded part is not secured to the remainder of the web. When such a 
product is made, the glue is of course not applied. Furthermore, the 
invention is not limited to use with offset printing processes as the 
invention may be practiced in conjunction with other printing processes 
such as rotogravure, flexigraphic and letter press, to name a few. 
The advantages of the present invention, as well as certain changes and 
modifications of the disclosed embodiments thereof, will be readily 
apparent to those skilled in the art. It is the applicant's intention to 
cover by his claims all those changes and modifications which could be 
made to the embodiments of the invention herein chosen for the purposes of 
the disclosure without departing from the spirit and scope of the 
invention.
