Description
A board comprising a paper facing having a plurality of score lines impressed in the facing, and
a paper medium that includes fibers substantially aligned in a machine direction and further
including a plurality of flutes whose respective axes are also aligned in the machine direction.
The paper medium is coupled to the paper facing such that the score lines are parallel to the
axes of the flutes and the fibers of the paper medium, and wherein each score line is equidistant
from each of two adjacent flute axis . Conventional corrugated board may feature a crosscorrugated
medium and one or more facing that have no score lines that are impressed (at
least prior to assembly with the corrugated medium). Such a conventional board product may
be inferior because any score lines that are sed will damage the underlying corrugated
medium in some manner. A breakdown in the strength of the underlying medium leads to poor
precision when the al board t is scored, cut, and folded. A lack of precision in folding
a board product leads to gap ion and fishtailing as any articulated portion of the board
product may not maintain a precise plane of articulation when folded.

SYSTEM AND METHOD FOR ING A FACING FOR A BOARD PRODUCT
WITH STRATEGICALLY PLACED SCORES
BACKGROUND
Modern making techniques use paper machines at paper mills to produce
rolls of paper that, in turn, can be used by board makers to produce board products (i.e.,
corrugated board). As a result, rolls of paper may be produced from machines that
operate continuously. Modern paper machines typically produce paper from a number
of substances including wood pulp that comprise wood fibers (although other fibers may
also be used). These fibers tend to be elongated and suitable to be aligned next to one
another. The fiber starts as a slurry that can be fed onto a moving screen from a head
box of the paper machine. In modern paper es, the fibers tend to align with each
other and align with a direction in which the screen is moving. This alignment ion
of underlying fibers is called the major direction of the paper and is in line with the
machine direction. Thus, the major direction is often simply called the machine direction
(MD) and the paper that is produced has an associated MD value.
When paper is used to make a board product, portions or layers of the board
product may be ated. Conventional corrugating machines will corrugate the
underlying paper product in the cross direction (CD) of the paper thereby failing to take
advantage of the natural strength bias of the paper in the machine direction. Further,
the greater natural th ies of paper in the machine direction are left
unharnessed by cross corrugation techniques in board making solutions. Further yet,
conventional corrugated medium includes flutes that take on a sinusoidal shape
because of the shape of the protrusions in a conventional pair of corrugating rolls. As a
result, companies that produce conventional board products remain ched in old
production processes that limit the strength of the board product.

DETAILED DESCRIPTION
The following discussion is presented to enable a person skilled in the art to
make and use the subject matter disclosed herein. The general principles described
herein may be applied to embodiments and applications other than those detailed
herein without departing from the spirit and scope of the present detailed ption.
The present disclosure is not intended to be limited to the embodiments shown, but is to
be accorded the widest scope tent with the principles and features disclosed or
suggested herein.
By way of overview, the subject matter disclosed herein may be directed to a
system and method for producing a board product made from paper products that have
a pre-scored facing in addition to a medium (sometimes called fluting) such that precise
articulation may be induced. A conventional board product may feature a crosscorrugated
medium and one or more facings that have no score lines that are imprinted
(at least prior to assembly with the corrugated medium). Such a conventional board
product may be inferior because any score lines that are imprinted will damage the
underlying corrugated medium in some manner. A own in the strength of the
underlying medium leads to poor precision when the eventual board product is scored,
cut, and . A lack of precision in a folded container leads to gap variation and
fishtailing, as any articulated portion of the board product may not in a precise
plane of articulation when folded. Hence, the lated portion “fishtails” out of
alignment.
Having a pre-scored facing (sometimes called wall or liner) with strategically
placed score lines (e.g., strategically placed with respect to an eventual articulation
point and/or with respect to underlying flutes in an attached medium), eliminates
problems with fishtailing. This is because the pre-score lines bias the facing to give way
at the score lines when articulated. As a result, the fold line on the facing is precisely
aligned along the pre-score line g any fold aligned with a desired box corner
n) as well as precisely placed with respect to any underlying flutes (making any
fold also d with the flute pattern). The effects of pre-score lines in a facing may be
enhanced when used in conjunction with an embossed medium that t greater
structural characteristics when compared to conventional cross-corrugated medium.
These advantages and additional aspects of various embodiments of the subject matter
sed herein are discussed below with respect to FIGs. 1-8.
FIGs. 1A-1B are views of a conventional board product 100 before and after
major fold articulation without benefit of score lines in one or more facings. As
discussed briefly in the summary, score lines will assist with board lation such that
lation of the board product is precise. In an effort to show problems of
conventional board product 100, the views in FIGs. 1A-1B are shown and then various
problems with an eventual container are shown in FIGs. 2B-2C to illustrate the effects
of the problems of the conventional board product 100. A conventional board product
100 may have some form of a medium 103 that is attached to a first facing 101 and a
second facing 202. Of course, these facings do not have any score lines predisposed.
As such, certainly there are no score lines in register to the flutes of the medium 103.
Further, the medium 103 may also be a conventional cross-corrugated medium having
flutes aligned in the cross direction (discussed further below) of the paper of the
medium 103.
When one wishes to late the board product 100, which is often the case
when the board product is eventually used for containers and boxes, a machine may
produce a score line (or mes, an indentation, an impression, or some other form
of marking in order to induce a fold line) at a line intended for lation (e.g., intended
to be a corner or fold point without reference to underlying flutes). Thus, in looking at
, a fold may be intended at point 104. As can be seen, the board product 100 is
being lated (at approximately 180 degrees in this view). A 180 degree fold is
sometimes called a major fold and may be a manufacturer requirement for producing
folded box blanks. A blank is an unfolded container in a flat open state (as shown ) that is manufactured to eventually be manipulated into a container or box. A
conventional regular slotted ner (RSC) blank is discussed below with respect to
FIGs. 2A-2C.
When a e makes an impression in the board product in production of a
blank, a mechanical impression collar may be used to impress a crease line at a
specific location. This location is in relation to an edge of the blank (e.g., 36 inches from
the edge of the blank, as but one example); such a location, in conventional methods, is
not in on to underlying flutes of the medium. As a consequence, when the
mechanical impression collar impresses a fold line, any underlying flutes that happen to
be within the impression area are crushed. By crushing the interior flutes, a significant
localized amount of board ure is compromised. Thus, the fold point 104 begins to
flex inward and the exterior fold point begins to stretch out around the fold. The interior
flutes around the fold begin to narrow as the two legs begin to come together.
shows the conventional board product in full 180 degree articulation.
The first facing 101 has been folded in half so as to come into contact with itself. The
second facing 102 has hed enough at point 104 to accommodate the additional
distance around the 180 degree fold point 104. As can be seen, the interior g of
the medium 103 loses ure as the localized flutes are significantly damaged.
Further, the second facing 102 may often re at the 180 degree fold point 104.
Such fracturing weakens the board product at point 104 significantly. As a result of the
fold point 104 causing a breakdown in medium structure as well as possible fracturing in
one or more facings, additional undesirable variations in the eventual container or box
product will exhibit. These undesired variations are discussed next with respect to
FIGs. 2A-2C.
FIGs. 2A-2C show various states of a blank 105 having slots 106 cut and
conventional impression lines 108b, 108c, 108d and 108e such that the blank 105 may
be manipulated into a container. In , the blank 105 is shown where a board
product may be altered to have the desired features, such as slots and impression lines.
Thus, the board product may have a pairs of slots 106 that have been cut along
eventual fold lines 108b, 108c, 108d and 108e. The slots 106 should be precisely
aligned and sized for the intended purpose and the dimensions shown in are
for illustrative purpose only as but one example of a flat blank 105. As a typical
ement for the end user of a blank, the left-most panel 107a may be folded (at fold
line 108b) 180 degrees to lay flat on top of panel 107b. This 180 degree fold is called a
major fold. Similarly, the right-most panel 107d may be folded (at fold line 108d) 180
degrees to lay flat on top of panel 107c. Once folded, the ends 108a and 108e of the
blank 105 may then be situated adjacent to each other with a glue lap 109 positioned to
in an overlapping manner such that the edge 108a may be adhered to the glue lap 109.
When precisely d, the edge 108a is positioned next to the edge 108e such that
the distance n edges 108a and 108e is the same width of other slots 106 in the
blank 105.
When articulated in the manner, the knocked down container blank 105 may be
in a folded condition to be fed into a machine for erecting a box or container from the
blank. Such an articulation may be useful for packaging and ng the resultant
knocked-down container blank 105 prior to being erected into the box or container.
These articulations, when performed on conventional board product, often lead to
undesired variations as shown in -2C.
A first undesired variation is shown in and is called a gap variation. Gap
variation may occur when the edge 108a and 108e are not precisely aligned adjacent to
each so as to exhibit a gap that is the same as the width of other slots when the glue lap
109 is adhered to the panel 107a. The gap may be too narrow if the major folds at folds
lines 108b and 108d are rolled inward and may be too wide if the major folds at folds
lines 108b and 108d are rolled inward. In this view, one can see that the panel 107a
has been articulated 180 s along major fold line 108b and panel 107d has been
articulated 180 degrees along major fold line 108d. However, the glue lap 109 does not
significantly overlap the panel 107a and the edges 108a and 108e are too far apart.
Without precise overlap, the edges 108a and 108e with glue lap 109 may not be in
position to be properly adhered to each other. This gap variation may be caused by
compromised major fold lines 108b and 108d because of a lack of precision in the fold
lines. Another variation that is not shown in the figures may be when the edge 108a
and 108e are too close or even overlap. Gap variations may be characterized as the
glue lap having too much overlap or not enough overlap (or even no overlap) and is a
variability that leads to undesired problems in the ed ner.
A second undesired variation is shown in and is called “fishtailing.”
Fishtailing occurs when the fold results in one or more panels being not parallel with
other panels. In the example shown in , the panel 107a is not parallel with the
panel 107d. As such, the edge 108a is also not el with the edge 108e and the
glue lap will not interface with the panel 107a in a precise manner Here, the major fold
108b may be precise , but the major fold 108d is not precise and results in the
folded over panel 107d fishtailing out of alignment. This results in problems for set-up
machines that erect the RSC blanks into boxes or containers.
The problems shown in FIGs. 2A-2C typically occur because of scoring and
folding conventional board product without regard to the position of any underlying flutes
in the medium. In on, after-assembly scoring (e.g., scoring that occurs after a
board product is assembled) causes damage to flutes as collateral flutes becomes
partially or completely crushed to prevent the flutes from ng the fold line on either
side of the desired fold position. Not only does this degrade board/box strength, it
allows for irregular folding (rolling scores), ing in gap variation, as measured at the
manufacturers joint. These and other problems may be overcome by pre-scoring
facings and then ling a board product with score lines in register to the
underlying flutes of the medium.
Prior to discussing the various embodiments, a brief discussion about cross
corrugating and linear embossing is presented. As has been y stated above,
conventional board products include a conventionally produced corrugated medium
(sometimes called a ated fluting), e.g., a cross-corrugated medium. A crosscorrugated
medium has flutes formed perpendicular to most underlying fibers of the
paper product. This results in flutes that are not aligned with the majority of underlying
fibers and, therefore, do not take age of the natural strength of the MD value of
the paper (when compared to the CD value). Such a failure to s the MD value of
the paper leads to loss of opportunity in the manufacturing of board products when
ic board strength is to be ed. That is, it will necessarily take more paper
(heavier paper, larger flutes, and the like) to realize the required board th.
A linearly-embossed medium is different from a cross-corrugated medium in that
the induced flutes are aligned with the MD value of the paper product. This results in
flutes that are aligned with the majority of underlying fibers and, therefore, take
advantage of the natural strength of the MD value of the paper (when compared to the
CD value). Harnessing the MD value of the paper leads to efficiencies in the
manufacturing of board products when specific board strength is to be realized. That is,
it will necessarily take less paper (lighter paper, smaller flutes, and the like) to realize
the required board strength. Aspects of making, ing, and using linearly
embossed mediums are discussed in greater detail in U.S. Patent Application No.
/077,250 entitled “SYSTEM AND METHOD FOR INDUCING FLUTING IN A PAPER
PRODUCT BY EMBOSSING WITH RESPECT TO MACHINE DIRECTION” and filed on
March 22, 2016, which is incorporated herein by reference in its entirety and for all
purposes. Some aspects of a linearly embossed medium are discussed below with
respect to Next, aspects of a pre -scored liner are discussed with respect to
is an isometric cutaway view of a scored facing 110 that may be part of
one or more board products ing to one or more embodiments of the subject
matter disclosed herein. In this embodiment, a facing may be produced having a MD
value in the MD direction 122 and having a weight and als commonly used for a
board product facing. The facing 110 may mes be called a liner or wall as this
layer of a board product is often an innermost n of the board product. As was
briefly discussed above, a facing 110 may often be scored to elicit articulation along a
particular line. However, if the facing has already been coupled with one or more
additional layers of a board product (e.g., a corrugated medium, an embossed medium,
another facing, and the like), then the scoring process will not only leave an impression
on the facing 110, but also on any other layer in the board t. As shown in FIGs.
2B-2C, such after-assembly g leads to undesired variations and structural
damage of the additional layers of the board product, which, in turns, weakens the
board product icantly at the articulation point.
The ment of however, may be a facing 110 that has undergone a
pre-scoring process such that score lines 115 are impressed into the facing 110 prior to
the facing 110 being combined with any other paper product (e.g., any other layer of a
board product). In the embodiment shown in the pre-score lines 115 are
stant with respect to each other and may be strategically spaced to also be in
alignment with an eventual embossed medium (not shown in having flutes of a
similar specific pitch dimension. Further, the score lines may be continuous
impressions into the facing 110. However, the “score” line may be any localized
weakening of the facing 110 at the desired point of fold of the board product that is
strategically placed with respect to the underlying flutes. In other embodiments then,
the score may be a crease impression (continuous linear or intermittent), partial slit
through the facing 110 (continuous linear or ittent), perforation in the facing 110,
and the like.
In other embodiments not shown, the pre-score lines 115 may be less than
consistent across a facing 110. For example, two score lines 115 may be grouped
together at approximately five mm apart from each other and then spaced apart from
another grouping of two of these five-mm-spaced score lines. In yet another e,
only a single grouping of scores may be present on a facing or even a single score line.
Although five mm intervals are given as an example, any width of interval may be
possible and common intervals will match common flute profiles, such as C-Flute, BFlute
, R-Flute and the like. These groupings may correspond to anticipated articulation
points for a specific box machine. However, for the purposes of efficient production of a
consistent facing 110, score lines 115 may be impressed by a scoring e at
strategically selected als (e.g., every five mm) such that any portion of the prescored
facing 110 may be combined with other layers of an al board product.
The embossed medium 130 of may be one such additional layer.
is an isometric cutaway view of an embossed medium 130 that may be
part of one or more board products according to one or more embodiments of the
subject matter disclosed herein. This diagram shows an isometric view of a portion of
an embossed medium 130 that may be formed from an embossing process. That is,
flutes 131 are formed from g the initial paper product through embossing rolls
using a linear-embossing technique such that the flutes 131 are formed ent with
a majority of underlying fibers 125 of the paper. The flutes 131 are also formed
congruent with the machine direction 122. A ly -embossed medium 130 harnesses
the natural strength of the paper in the machine direction 122 as the flutes 131 are
formed in the machine direction 122 of the paper (e.g., congruent with a majority the
underlying fibers 125). Therefore, a ly -embossed medium 130 harnesses the
natural strength of the paper in the machine direction 122. Such an embossed medium
130 may be a component/layer of a board product as discussed below with respect to
Further, as is shown in the flutes 131 may form a ular pattern when
viewed from a cutaway perspective. This flute pattern having a triangular repeating
shape is referred to as a flute profile. This flute e provides an improvement in
structural integrity of the embossed medium 130 when compared to a flute profile the
exhibits a curvilinear or sinusoidal flute profile. Such a curvilinear or sinusoidal flute
profile is prevalent in conventional cross-corrugated mediums. Therefore, the triangular
flute profile as shown in is also superior to corrugated s with respect to
board strength and structural integrity. The flute profile exhibits apexes 132 that may be
d to a facing (not shown). The apexes may be spaced apart in a repetitive
manner at a specific distance (such as five mm, for example). As will be discussed
next, when coupled to a matching ored facing 110 of the apexes 132 of
the embossed medium 130 may be precisely d in a desired manner to yield
precise and less damaging articulation of any resulting board product.
is an isometric cutaway side view of a board product 300 having the
scored facing 110 of and the medium 130 of according to an embodiment
of the subject matter disclosed herein. In this embodiment, the board t 300
includes three layers: the first facing 110, the medium 130, and a second facing 140.
As is shown, the first facing 110 may form an inner wall (although the top/bottom
direction reference to alignment of the board product 300 is arbitrary) that is coupled to
one side of the embossed medium 130. The coupling may be through an adhesive
applied to the apex of each flute on the top-side of the medium 130 such that the facing
110 is glued to the medium 130 where adhesive is applied. In other embodiments, glue
may be applied to the entirety of the facing 110 prior to being coupled to the medium
Likewise, a second facing 140 may form a -side outer wall , the
top/bottom ion reference is ary) that is coupled to an opposite side of the
embossed medium 130. The coupling may be through an adhesive applied to the apex
of each flute on the bottom-side of the embossed medium 130 such that the facing 140
is glued to the embossed medium 130 where adhesive is applied. In other
embodiments, glue may be applied to the entirety of the facing 140 prior to being
coupled to the embossed medium 130.
The score lines 115 are aligned in the direction of underlying flutes of the
embossed medium. Both the score lines and the flutes are also aligned with the
machine direction 122 of the ying paper in the scored facing 110, the facing 140
and the medium 130. Further, in this embodiment, the score lines 115 of the scored
facing 110 are aligned in a manner such that the score lines are placed equidistant from
respective apex locations of the affixed embossed medium. For example, if the top-side
apexes of the embossed medium 130 are spaced five mm apart from each other, then
the score lines 115 are also spaced five mm apart from each other, but offset by 2.5
mm. That is, for every pair of de apexes that are five mm apart, the affixed facing
110 features a score line 115 half way between each pair of top-side apexes at
approximately 2.5 mm from each one.
With precisely placed score lines in a facing that is affixed to a medium having
linear flutes, precise articulation lines may be induced. That is, if one were to fold the
board product 300, the scored facing would give way along one or more score lines in a
precise manner. That is, the fold would precisely lie in a single plane that is normal to
the score line being articulated. Such a fold may be precise and will serve to prevent
the articulation direction from veering out of the normal to the plane of the score line. In
other embodiments (not shown), the bottom-side facing 140 may also be pre-scored
with a similar pattern of score lines precisely aligned with -side apexes of the
embossed medium 130. Further, the pre -scored lines in any facing may cover less than
all of the area of the facing (e.g., only score lines in anticipated lation points).
When all three layers are assembled and d, the resultant board product 300
is or to conventional board product because of several factors. First, because the
flutes of the embossed medium 130 are strategically aligned with respect to the score
lines of the pre-scored facing 110, any articulation of the board product will be precise
resulting in cy in the ed box container. Such precision prevents gap
variation and fishtailing. Further, the linearly embossed medium 130 es a flute
profile that exhibits superior strength because of the leg structures of the triangular
nature of each flute. Further yet, adhesive may be continuously and uniformly applied
to each apex in a predictable manner with greater precision as portions of the adhesive
will not spill over to the legs as may be the case with sinusoidal apexes having no flat
receiving area. Lastly, a pre-scored facing 110 prevents having a scoring step after
board ly that leads to damage of ying layers (e.g., the embossed medium
130) when conventional board g techniques are used.
FIGs. 6A-6C are a series of views of the board product 300 of being
articulated with benefit of score lines in one or more facings according to an
embodiment of the subject matter disclosed herein. In , the board product 300
is shown from an edge view so as to better rate what happens when the board
product 300 is articulated. As shown, the board product 300 includes a first facing 110,
a second facing 140 and a medium 130. The medium 130 is disposed between the first
facing 110 and the second facing 140. The first facing may further include score lines
115. In this example view of , the first facing 110 is shown facing down simply
for illustrative purposes. Further, only two score lines 115 are shown for ease of
illustration as there may be many more score lines in register to the flutes of the
medium 130 including score lines on the second facing 140 as well. Further yet, the
medium 130 is shown having a sinusoidal flute profile, though it is understood that any
shape of flute profile may be used.
In the next view of , the board product 300 has begun articulation. Here,
the fold lines will follow precisely the score lines 115 in the facing 110. Thus a first fold
point 603 corresponds to a first score line 115 and a second point 604 corresponds to a
second score line. As can be seen is this view of , an articulation that will result
in an eventual 180 degree articulation will comprise two different folds of approximately
90 degrees each. Further, the first fold point 603 is located directly between two apexes
(of rd facing flutes – i.e., two apexes affixed to the first facing 110) of the
medium 130 such that the legs of this flute begin to move toward each other. As a
result, a first stretch point 601 of the second facing 140 begins to forms directly over the
first fold point 603. Similarly, the second fold point 604 is located directly between two
apexes (of downward facing flutes – i.e., two apexes affixed to the first facing 110) of
the medium 130 such that the legs of this flute also begin to move toward each other.
As a result, a second stretch point 602 of the second facing 140 begins to forms ly
over the second fold point 604.
In , the board product 300 is shown fully articulated to the 180 degree
position. Thus, the first stretch point 601 and the second stretch point 602 are each
approximately 90 degrees. Different from the conventional example of FIGs. 1A-1B
where the h point folded a full 180 degrees, this ment accomplishes a full
180 s of board product articulation with only having imately 90 degrees of
fold causing a stretch at any given location. Having a full 180 degree articulation with
only 90 degrees of stretch at any given point leads to less stress at the stretch points to
underlying fibers in the facing 140. This, in turn, leads to r strength at corners of
boxes and containers due to less stretch damage to the facing 140 and no loss of flute
structure in the medium 130.
Further, the fold points 603 and 604 fold all the way into a respective flute such
that secondary flutes are formed to provide additional corner structure from liner 110.
That is, at the first fold point 603, a first secondary fold flute 610 is formed from facing
110 inside of a first primary fold flute 605. Likewise, a second secondary fold flute 611
is formed from facing 110 inside of a second primary fold flute 606. Secondary flutes
610 and 611 provide additional corner strength in boxes and containers.
shows a side-by-side comparison of an articulated tional board
product 100 and an articulate board product 300 of As can be seen, the
conventional board 100 shows a distortion in the medium ure at and nt to
the 180 degree articulation point. Here, the underlying flutes have been compromised
because the fold point did not happen to line up with a respective flute in the medium.
This corner will have trably less predictability in folding. Differently, the
embodiment of the board product with precisely located score lines exhibits the
additional secondary flutes as discussed above with respect to . This
articulation point in the board product 300 will have superior strength when compared to
the conventional example 100.
FIGs. 8A-8B are views of a board product before and after articulation with
benefit of one score line in one or more facings according to an embodiment of the
subject matter disclosed herein. In , the board t 800 is shown from a
edge view so as to better illustrate what happens when the board product 800 is
articulated. As shown, the board product 800 es a first facing 810, a second
facing 840 and a medium 830. The medium 830 is disposed between the first facing
810 and the second facing 840. The first facing may further include one score line 815.
In this example view of , the first facing 810 is shown facing down simply for
illustrative purposes. Further, only one score line 815 is shown that is precisely located
below an apex of a flute in the medium 830. Further yet, the medium 830 is shown
having a sinusoidal flute profile, though it is tood that any shape of flute profile
may be used and the medium 830 may be embossed or corrugated.
In the next view of , the board product 300 has begun lation. Here,
the fold line will follow precisely the score line 815 in the facing 810. Thus a first fold
point 804 corresponds to a first score line 815. As can be seen is this view of ,
an articulation will result in an eventual approximately 90 degree lation without
damage to underlying flutes. Further, the fold point 804 is located directly between two
apexes (of downward facing flutes – i.e., two apexes affixed to the first facing 810) of
the medium 830 such that the legs of this flute begin to move toward each other. As a
result, a stretch point 805 of the second facing 840 begins to forms ly over the fold
point 804. With a precisely located score line 815, a 90 degree fold may be realized
without causing undesired damage to the flutes of the medium 830. Additional aspects
of various embodiments of board products are discussed next with respect to the

is a diagram of aspects of a machine 500 configured to produce the board
product 300 of according to an embodiment of the subject matter disclosed
herein. The machine 500 may produce other embodiments as well including the
embodiment of the board t 800 from . The machine 500 includes three
feed rolls 510, 530, and 540 of paper that are used to produce a board product. These
feed rolls include a first facing feed roll 510, an ed medium feed roll 530, and a
second facing feed roll 540. Note that the paper that is wound on the first facing feed
roll 510 is prior to scoring and the paper that is wound on the embossed medium feed
roll 530 is prior to embossing. The weights and composition of the paper for each
respective feed roll may be different and designed specifically for the respective
purpose.
The paper from each roll may be d from each respective roll and fed
toward a combiner 550 that is configured to combine the various layers of paper
together to form a resultant board product. Prior to entering the combiner 550, at least
some of the paper from the feed rolls may be passed through one or more stages for
scoring the paper. Thus, the first facing feed roll 510 may feed paper into a scoring
stage 590 that scores the paper with impressions in a precise manner. In other
embodiments, the lines impressed upon the facing 110 may be perforations, intermittent
cuts or some other form of localized weakening the facing 110 along a precise line. As
the paper exits the scoring stage 590, it becomes the scored facing 110 as sed
above with t to The scored facing 110 is then fed into the combiner 550
to be combined with other materials.
Further, also prior to entering the combiner 550, at least some of the paper from
the feed rolls may be passed through one or more stages for forming the paper into a
medium. As used herein and in the industry, a medium may refer to a paper t
that has been formed into paper having flutes. Thus, the embossed medium feed roll
530 may feed paper into first and second embossing rolls 531a and 531b that are
aligned with respect to each other. As the paper exits the embossing stage (e.g.,
embossing rolls 531a and 531b), it becomes the embossed medium 130 as discussed
above with respect to The embossed medium 130 is then fed into the combiner
550 to be combined with other materials.
Once passed through the embossing rolls 531a and 531b, the embossed
medium 130 may be passed to an applicator 570 for ng adhesive to the newly
formed apexes. The ator may include a device for identifying the locations of each
apex and then aligning a series of adhesive dispensers with the identified apexes. In
other ments, adhesive may be transferred to the flute tips with a glue roll or rolls
where the paper contacts a glue film and adheres to the flute tips. In this manner,
ve may be applied with precision in a uous and uniform manner. Then, the
first facing 110, the embossed medium 130, and the second facing 140 are combined in
the combiner 550 using various techniques such as adhesion, curing, wetting, drying,
heating, and chemical treatment. The resultant board product 300 features at least one
scored facing ely d with at least one linearly-embossed medium 130
wherein the board product may be articulated with accuracy.
While the subject matter discussed herein is susceptible to various modifications
and alternative uctions, certain illustrated embodiments thereof are shown in the
drawings and have been described above in detail. It should be understood, however,
that there is no intention to limit the claims to the specific forms disclosed, but on the
contrary, the intention is to cover all modifications, ative constructions, and
equivalents falling within the spirit and scope of the claims.
