Description
FIELD OF THE INVENTION
This invention relates to continuous business forms, and more
particularly, to a continuous business form bearing one or more
removable, pressure-sensitive labels, as well as a message or
record-bearing section.
BACKGROUND OF THE INVENTION
As is well known in the continuous business form art, there is a
large variety of uses for label bearing continuous business forms.
One particularly popular type of label bearing form includes one
section which is provided with one or more pressure-sensitive
adhesive backed labels and an adjacent section on which variable
information may be printed and retained.
Of this general type, there are two differing constructions which
are in use today. In one, a relatively wide ply is adhered to a
relatively narrow ply by pressure-sensitive adhesive contained on
the former. At least at the point of adhesion of the former to the
latter, the narrow ply is coated with a waxy material so as to
serve as a conventional release liner for the narrow ply, which in
turn, defines a pressure-sensitive adhesive label section overlying
the narrow ply.
The part of the wide ply that does not overlie the label section
then serves as a record or message bearing portion of the business
form.
One difficulty with this construction is that the wide ply serves
as both the label section and the record or message bearing portion
of the form which means that in those instances where it is
desirable for any of a variety of reasons that the label be formed
of a material or stock different than that used to form the record
or message bearing portion, such a construction cannot be
satisfactorily employed.
Another prior art construction, which is not subject to the
foregoing difficulty, is one wherein conventional adhesive label
stock is adhered to conventional business form or record keeping
stock. To provide a record or message bearing portion for the
business form, a longitudinal glue line is placed along one edge of
the release liner on the side thereof opposite the label stock, and
an elongated ply adhered to the combined release liner and label
stock by such glue line.
In this construction, the added ply serves as the record or message
bearing portion and obviously can be formed of any suitable or
desired material, which can be quite different from that utilized
in forming the release liner. However, in some sorts of processing
equipment, this type of form can pose a difficulty because of the
thickness of the form at the junction of the record or message
bearing ply and the release liner. In particular, the thickness of
the form at this location is equal to the sum of the thickness of
the record or message bearing ply, the thickness of the release
liner, the thickness of the label stock, the thickness of the
pressure sensitive adhesive between the release liner and the label
stock, and the thickness of the glue line adhering the release
liner and the record or message bearing stock. This thickness adds
rigidity to the form which may make processing on certain types of
equipment difficult. In addition, in some cases, the thickness
alone may tend to cause form components to hang up in certain types
of printers or the like.
The present invention is directed to overcoming one or more of the
above problems.
SUMMARY OF THE INVENTION
It is the principal object to provide a new and improved business
form. More specifically, it is an object of the invention to
provide a new and improved business form of the label bearing type
which is additionally provided with a record or message bearing
section.
An exemplary embodiment of the invention achieves the foregoing
object in a business form including an elongated ply of label stock
of a desired width and having one side coated with a pressure
sensitive adhesive. An elongated ply of release liner stock of
about the desired width and having a release side engaged with the
adhesive is provided. The release liner and the label stock ply are
laterally offset from one another so that a narrow longitudinal
strip of adhesive unengaged with the release liner exists. An
elongated ply of record or message bearing stock is adhered at one
edge to the label stock at the narrow longitudinal strip of
adhesive.
As a consequence of this construction, the release liner and the
record or message bearing stock may be of different materials while
the thickness of the form where the record or message bearing ply
is adhered to the label stock is equal to the thickness of both
plus the thickness of the pressure sensitive adhesive, a
considerable reduction over prior art constructions wherein the
release liner and the record or message bearing stocks are of
different materials, and no greater than the thickness of the prior
art constructions requiring the release liner and the message or
record bearing ply to be of the same stock.
A preferred embodiment of the invention contemplates that the
longitudinal edge of the release liner remote from the narrow
longitudinal strip of adhesive is uncovered on both sides and
includes aligned holes defining a control punch margin for form
feeding purposes.
The invention also contemplates that the form be delimited into
individual form lengths by cross lines of weakening extending
across the plies.
The invention further contemplates that the release liner and the
label stock plies be of equal width and be laterally offset from
each other by firstly delaminating coextensive release liner and
label stock plies, laterally shifting one of such plies relative to
the other, and relaminating the release liner and label stock
plies.
Die cuts may be provided in the label stock to define individual
labels that may be peeled from the release liner stock.
Other objects and advantages will become apparent from the
following specification taken in connection with the accompanying
drawings.

structure; and
FIG. 5 is a view similar to FIGS. 3 and 4, but of another type of
prior art structure.
DESCRIPTION OF THE PREFERRED EMBODIMENT
An exemplary embodiment of a continuous business form made
according to the invention is illustrated in the drawings and with
reference to FIG. 1 is seen to be folded in a zigzag folded stack,
generally designated 10. Alternatively, the business form could be
in cut sheet form if desired. The form is composed of a plurality
of individual form lengths 12 folded as stated on cross lines of
weakening 14 which are generally in the form of perforations
extending across the plies defining the form.
According to the invention, three plies are utilized to define the
business form. A first is an elongated ply 16 of label stock (FIGS.
2 and 3) coated on one side with pressure sensitive adhesive 18 as
schematically illustrated in FIG. 3. The side of the ply 16
opposite the adhesive 18 is adapted to be printed upon in any
suitable fashion.
A second ply is an elongated ply of conventional release liner
stock 20. According to the preferred embodiment of the invention,
the width of the release liner ply 20 is equal to the width of the
label ply 16. However, this is not an absolutely necessary
relationship as will appear.
The side of the release liner ply 20 facing the label ply 16 will
typically be coated with any of a variety of known, relatively waxy
substances to facilitate peeling of the label ply 16 from the
release liner stock 20.
According to the invention, and as seen in FIGS. 2 and 3, the plies
16 and 20 are laterally offset from each other. Opposed
longitudinal edges of the ply 16 are shown at 22 and 24, while
opposed longitudinal edges of the ply 20 are shown at 26 and
28.
As a consequence of this, a relatively narrow longitudinal strip 30
of adhesive 18 on the ply 16 that is not contacted by the ply 20
exists immediately adjacent the edge 24. Additionally, the
longitudinal edge 26 of the ply 20 remote from the strip 30 is seen
to be uncovered on both sides, and as best seen in FIG. 2, includes
a series of aligned holes 32 defining conventional pin feed holes
that the form is provided with an elongated control punch margin
34. If desired, the ply 20 may be provided with a longituduinal
perforation 36 in alignment with the edge 22 of the ply 16 so as to
allow the control punch margin 34 to be removed.
A record or message bearing ply of any desired stock is shown at
40. One longitudinal edge 42 of the ply 40 underlies the ply 16 at
the narrow longitudinal strip 30 and is adhered to the ply 16 by
the adhesive at that location. If desired, the ply 40 may have a
longitudinal line of perforation 44 that underlies the edge 24 of
the ply 16 so as to allow separation of the two. Alternatively or
additively the ply 16 may include a line of perforation 45 aligned
wiht the edge 28 (or, for that matter, the edge 42 or located just
either side of either) to allow the label and release liner to be
separated from the record ply 40 after it has been printed upon.
The ply 40, at each form length, is adapted to be printed with
variable information by a printer as is well known.
Parts of the ply 16 may be provided with label shaped die cuts 46
to define individual labels 48 surrounded by a matrix strip 49. The
labels 48 may be removed from the form by peeling from the ply 20
as desired. Alternatively, the labels 48 could be formed by butt
cutting or perforating the ply 16 and the matrix strip 49
omitted.
A preferred method of making the business form involve the
utilization of a release liner of a given width adhered, in
coextensive relation, to a ply of label stock of the identical
width. The two plies are delaminated utilizing conventional
equipment, and one of the plies, by means of angle bars or the
like, is moved laterally sufficiently to produce the desired
offset. The release liner and label stock plies are then
relaminated and the record or message bearing ply adhered to the
label ply at the longitudinal strip 30.
During such processing, printing of the various plies may occur as
desired, and after the delamination, the pin feed holes 32 added.
The die cuts 46 will typically be disposed in the form following
relamination.
As an alternative, where the control punch margin 34 is not
required, a running cut could be made through the release liner ply
20, only. The resulting strip is removed to expose the adhesive on
the ply 16. The record ply 40 is then joined to the exposed
adhesive. This allows the form to be produced without requiring
delaminating and ply shifting equipment.
As can be readily appreciated from FIG. 3 and the foregoing
description, the label stock ply 16 and the record of message
bearing ply 40 may be made of differing stocks if required by the
particular application to which the form is to be put since the two
are separate. This is in contrast to one type of prior art
constructions such as that shown in FIG. 4. In this construction, a
single relatively wide ply 60 serves as both the label section and
the message or record bearing portion of the form, having a release
liner ply 62 adhered as by pressure sensitive adhesive 64 to one
side of the ply 60 which has been treated to act as the release
liner.
Similarly, as can be seen from FIG. 3, at the junction of the
various plies, the maximum thickness of a form made according to
the invention is equal to the thickness of the pressure sensitive
adhesive 18, the thickness of the label stock 16, and the thickness
of the thicker of the release liner ply 20 or the record or message
bearing ply 40. This is in contrast to a prior art structure that
allows the release liner 20 and the record or message bearing ply
to be formed of differing materials such as is shown in FIG. 5. In
this case, the release liner ply is shown at 70 and is adhered as
by pressure sensitive adhesive 72 to the label stock ply 74.
Along one longitudinal edge of the assembly of the plies 70 and 74,
a glue line 76 is located on the ply 70 oppositely of the ply 74
and the record or message bearing ply 78 adhered to the assembly of
plies 70 and 74 by such glue line 76. As a consequence of this
construction, the thickness of the prior art form may be virtually
double that of a form made according to the invention. This may
cause processing difficulty because of the increased rigidity
and/or thickness; may cause refolding difficulties for the same
reason; and may cause packing difficulties because of the relative
thinness of the form to either side of the glue line 76 and
settling within packing cartons or the like ultimately resulting in
wrinkling.
Still a further advantage results when a form made according to the
invention is constructed by the method previously described. In the
usual case, a combined pressure sensitive adhesive coated label
stock and release liner such as shown at 70, 72 and 74 will be in
roll form. Thus, the radially inner one of the plies in the roll
will be of slightly shorter length from one end to the other, which
in turn can result in wrinkling of the longer ply as it is adhered
to the shorter ply in the length of the shorter ply. However,
according to the invention, such wrinkling is avoided since the
forces resulting from the difference in lengths are eliminated
during the delaminating and relaminating process.
