DOCUMENT CARRIER
Abstract
A document carrier envelope for processing checks through
automatic magnetic character recognition sorting equipment. The
document carrier includes generally rectangular back and front
sheets of approximately the same size. The front sheet is formed of
relatively translucent material so that a check carried by the
document carrier can be read, photographed or microfilmed and the
front sheet is adhesively secured to the back sheet along one of
the shorter side edges and along a line spaced from one of the
longer side edges of the sheets. An elongated magnetic
indicia-receiving strip is secured to the front sheet adjacent the
adhesively secured longer side edges.

automatic magnetic character recognition equipment comprising three
separate sheets including
a generally rectangular planar back sheet having top, bottom and
opposite side edges, the top and bottom edges being longer than the
side edges,
a generally rectangular planar front sheet formed of substantially
transparent material for permitting microfilming of a check carried
by the envelope, the material of the front sheet being such that it
is not readily imprintable with magnetic indicia, said front sheet
being generally coextensive with said back sheet and having top,
bottom and opposite side edges, the front and back sheets being
adhesively joined directly to each other along the bottom edges
thereof and along a line spaced from said bottom edges, said line
being spaced from the bottom edges at least three-eighths inch
whereby the bottom edge of a check carried by the envelope will be
supported at least three-eighths inch from the bottom edge of the

Description
BACKGROUND
This invention relates to document carriers for processing checks
and the like through automatic sorting equipment which operates by
reading magnetic characters.
The document carrier disclosed herein is an improvement over the
document carriers described in U. S. Pat. Nos. 3,043,506 and
3,431,404. As described in those patents, automatic sorting
equipment is commonly used by banks, clearing houses and other
institutions for sorting checks which carry indicia printed in
magnetic ink. However, several problems have arisen with respect to
the prior art document carriers. For example, it is desirable that
the document carrier be relatively sturdy so that it may pass
through the sorting equipment without difficulty. It is also
desirable that either the front sheet or both sheets which form the
carrier be formed of translucent or transparent material so that
the check can be read, photographed or microfilmed without removing
the check from the carrier. However, most translucent materials
such as glassine and cellophane are not only relatively flimsy but
are not readily imprintable with the magnetic indicia. Problems
have also been encountered in positioning the document carrier so
that the magnetic indicia can be accurately read by the sorting
equipment, particularly when the indicia are poorly printed.
Summary
The inventive document carrier includes a front sheet and a back
sheet which form a check-receiving enclosure. The front sheet is
formed of translucent or transparent material and permits the check
to be read, photographed or microfilmed. An elongated strip is
secured to the front sheet adjacent the bottom edge thereof, and
the strip is made of a material which may be readily imprinted with
the magnetic indicia. The strip also serves to position the
magnetic indicia closer to the read head of the sorting equipment,
thereby permitting the machine to function more accurately.
Further, the elongated strip provides the document carrier with a
strong lead edge.

DESCRIPTION OF SPECIFIC EMBODIMENT
Referring to the drawing, the numeral 10 designates generally a
document carrier or envelope in which is inserted a check 11 for
processing. The document carrier is seen to be generally
rectangular and is provided with relatively long top and bottom
edges 12 and 13, respectively, and relatively short side edges 14
and 15.
The document carrier includes a rectangular back sheet 16 and a
rectangular front sheet 17 which is generally coextensive with the
back sheet 16. The back sheet 16 is preferably formed of a material
which is strong enough to support the carrier as it passes between
the carrier belts or rollers of the sorting equipment, and about 20
pound sulfite bond or 20 pound glassine paper have been found to be
particularly satisfactory. The front sheet 17 is formed of a
translucent or transparent material such as glassine or cellophane
through which the check 11 is readily observable.
The front and back sheets are adhesively secured along the bottom
edges thereof and along at least one of the short sides of the
document carrier. Referring to FIG. 2, a layer 18 of adhesive
secures the sheets adjacent their lower edges, and the adhesive
layer extends upwardly from the lower edges to a line 19 which
extends generally parallel to the lower edge of the document
carrier. In the particular embodiment illustrated, the adhesive
layer 18 is laid down in continuous fashion along the entire length
of the document carrier by a conventional applicator roller or the
like, but it is to be understood that the lower edges of the sheets
could be secured in other ways. For example, glue bars, one
extending adjacent the lower edges of the sheets and the other
extending along the line 19 could be applied, or the adhesive could
be laid down intermittently rather than by a continuous roller.
In the particular embodiment illustrated, the front and back sheets
of the document carrier are adhesively secured along both of the
shorter sides 14 and 15 of the carrier by adhesive strips 20 and
21, respectively. However, if desired, these sheets could be
secured along only one of the shorter sides. The shorter side 14 of
the document carrier is generally the lead edge as the carrier
travels through the sorting equipment, and the front and back
sheets are preferably secured along at least this shorter side to
prevent folding back of one of the sheets as the carrier enters the
equipment.
An elongated strip 22 extends along the entire length of the bottom
edge 13 of the document carrier and is adhesively secured to the
front sheet 17. The strip 22 is advantageously formed of paper of
about 9 to 20 pounds weight and is preferably provided with a
vellum type of surface or a surface which is readily imprintable
with the magnetic ink used to form the magnetic indicia which are
read by the sorting equipment. The width of the strip 22 is
preferably about the same as the distance between the lower edge 13
of the document carrier and the line 19 which defines the upper
edge of the adhesive layer 18.
The adhesive layers 18, 20 and 21 define a check-receiving envelope
or enclosure into which the check 11 can be inserted. The check
generally carries some sort of magnetic indicia adjacent the lower
edge 23 thereof such as the numbers indicated generally by the
reference numeral 24, which would ordinarily be read by the check
sorting equipment. However, as is well known in the art, some
checks cannot be processed by the sorting equipment for a number of
reasons and must instead be carried by a document carrier on which
is printed the proper magnetic code by a standard encoding machine.
In the case of the inventive document carrier 10, new magnetic
indicia 25 can be imprinted on the elongated strip 22. When the
check 11 is inserted into the document carrier 10, the lower edge
23 of the check becomes wedged between the front and back sheets of
the document adjacent the upper end of the adhesive layer 18, and
the magnetic indicia on the check are thereby held away from the
magnetic read head of the sorting equipment. Instead, the magnetic
read head will scan the magnetic indicia 25 which are imprinted
along the strip 22 of the document carrier.
As illustrated in FIG. 1, the check 11 is clearly visible behind
the translucent or transparent front sheet 17 and the information
on the check can easily be read while the check is in the document
carrier. Further, the check can be photographed or microfilmed
without being removed from the document carrier. Heretofore, the
use of a translucent or transparent material for the front sheet or
both the front and back sheets created a problem in printing the
magnetic indicia on the document carrier. Generally, the clearer or
more transparent the sheet material, the less the sheet lends
itself to magnetic ink imprinting. This is so either because the
surface of this type of sheet is normally too slick to be
satisfactorily printed or because the sheet is an oil base or
vegetable material which tends to repel the magnetic ink. With the
inventive document carrier, however, even a material such as
cellophane can be used, and the document carrier is readily
imprintable with the magnetic ink.
We have also found that the use of a smooth material such as
glassine or cellophane permits the check to be inserted into the
document carrier more easily because of the low friction provided
by these materials. Also, the front sheet can easily be pulled away
from the stiffer back sheet to facilitate insertion of the check.
The top edge of the front sheet may also terminate below the top
edge of the back to further facilitate separation of the
sheets.
As used herein, the term "translucent" refers to the ability to
transmit light with or without substantial diffusion and is meant
to include the more limited term "transparent." For example,
cellophane and other transparent materials which transmit light
without substantial diffusion are to be considered translucent, but
glassine and other translucent materials which transmit but diffuse
light are not to be considered transparent.
Once the check is inserted into the document carrier, it tends to
be retained therein and will not flutter or fly out of the carrier
as the carrier is processed by the high speed sorting equipment.
This is so because the smooth surface of the glassine or cellophane
tends to "cling" to the check without any substantial air pockets
therebetween, especially after the document carrier passes through
the rollers or belts which are provided as part of the transport
system of the equipment. Further, as can be seen best in FIG. 4,
the bottom of the check tends to wedge between the front and back
sheets adjacent the bottom glue layer 18, and this wedging also
serves to retain the check in the carrier as the carrier is
processed. If the sheets are not properly secured and the check
wedges a substantial distance downwardly below the seal line 19
which ordinarily provides the bottom of the check enclosure, the
strip 22 will overlie the magnetic indicia on the check and will
prevent these indicia from being read in a substantial number of
sorting machines now being used. If desired, the strip can be made
of a relatively opaque material to decrease the ability of the
machine to read through the strip.
Not only does the strip 22 permit the magnetic indicia to be
imprinted more readily, but it positions the magnetic indicia for
more accurate reading by being closer to the magnetic read head of
the sorting equipment. Referring to FIG. 5, the document carrier
and check are generally carried through the sorting equipment by
rollers or belts 26 and 27 which are positioned above and below the
document carrier. The rollers or belts are not quite as wide as the
document carrier, and the read head 28 of the sorting equipment is
positioned adjacent the rollers generally above the bottom edge of
the item being processed. As illustrated, the elongated strip 22
carrying the magnetic indicia does not pass through the rollers or
belts and may therefore extend upwardly toward the magnetic read
head beyond the surface of the upper roller 26. The strength of the
signal transmitted by the magnetic read head is a function of the
distance of the object being scanned from the read head. Since the
magnetic indicia printed on the strip 22 are raised by the strip
above the surface of the front sheet 17, the strength of the
signals transmitted by the read head are therefore stronger and
more accurate than would be the case if the indicia were printed on
the front sheet 17.
Although the inventive document carriers have been in use for only
a short time, it is believed that the smooth surface provided by
the translucent or transparent front sheet 17 will cause less wear
on the carrier belts or rollers of the sorting equipment.
The strip 22 also adds strength to the lower right corner of the
document carrier, and particularly to the lower portion of the edge
14 of the carrier. The edge 14 is generally the lead edge of the
document carrier as it is processed, and it is desirable that this
edge be relatively sturdy. As the document carrier enters the
equipment, it passes through a nip provided by a pair of rollers
which separates the document carriers and feeds them to the sorting
equipment one at a time. If the lead edge is not sufficiently
strong, the document carrier might be folded or the sheets of the
carrier might be puckered.
The strip 22 also adds opacity to the portion of the document
carrier which carries the magnetic indicia. Most sorting equipment
include a photoelectric cell adjacent the magnetic read head to
activate the read head when the lead edge of the document carrier
passes the photoelectric cell. The strip 22 increases the opacity
of the document carrier and minimizes the possibility that the
photoelectric cell will fail to activate the read head.
The weight of the strip 22 is of the order of 9 to 20 pounds, which
is approximately the same as the weight of conventional checks, and
the thickness of the strip would also approximate that of the
check. Accordingly, the three-ply thickness of the document carrier
adjacent its lower edge is approximately the same as the total
thickness of the front and back sheets and the check, and the
thickness of the document carrier with check is approximately
uniform across the entire width of the carrier. The document
carriers may therefore be stacked evenly after sorting.
The dimensions of the various parts of the document carrier are
substantially dependent upon the sorting equipment and the size of
the checks. Most sorting equipment will read indicia printed within
about three-eighths to about five-eighths inch from the bottom edge
of the item being sorted, and it is therefore preferable that the
seal line 19 provided by the adhesive layer 18 be spaced from the
lower edge of the document carrier so that the indicia on the check
will be spaced from the lower edge of the document carrier at least
five-eighths inch. The width of the strip 22 should be sufficient
to provide a suitable field for imprinting, and will therefore be
approximately three-eighths to five-eighths inch. However, it is
desirable that the adhesive layer 18 be as wide as the strip 22 so
that the lower edge of check will not be positioned behind the
strip, thereby adding a further ply or layer to the lower portion
of the document carrier with check which might interfere with even
stacking.
While in the foregoing specification a detailed description of a
specific embodiment of the invention was set forth for the purpose
of illustration, it is to be understood that many of the details
herein given may be varied considerably by those skilled in the art
without departing from the spirit and scope of the invention.
