BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention relates generally to coin wrappers, and more particularly to coin
wrapping paper for denoting the denomination and value of coins wrapped therein.
2. Description of the Related Art
[0002] Many types of coin wrappers have been or are being used to enclose a plurality of
coins for handling purposes. These wrappers range from simple paper tubes, which are
typically filled manually with the proper denomination of coins, to elaborate, selectively
perforated, plastic and foil wrappers having indicia thereon, which are used in conventional
wrapping machines.
[0003] Presently, businesses which handle large quantities of coins, such as financial institutions
and casinos, are quite cost sensitive. Since manual wrapping typically incurs higher
costs than automatic wrapping, these businesses currently favor automatic wrapping
machines. Moreover, these businesses recognize the value of their employees' time
as it impacts service and overall throughput. Therefore, the resulting wrapped coin
rolls should convey information quickly, and should easily release coins when needed.
[0004] The coin handling industry considers these needs when servicing these various business
concerns. First, the wrapper should be inexpensive to manufacture and use, and should
be designed for use in an automatic wrapping machine. Second, the wrapper should convey
information to the end user, i.e., a bank teller, and should quickly and easily release
the coins when needed, while holding the coins securely together during rough handling.
[0005] Moreover, it is not uncommon for certain types of businesses to require special rolls.
Casinos and mass transit systems commonly utilize tokens which they offer in rolls
of varying value and size. For instance, "half wraps" are coin rolls which contain
half as many coins as a full roll. Since the "half wraps" are wrapped with paper sized
to wrap a full roll, a considerable amount of wrapping material is wasted.
[0006] Previous wrappers have fallen short of accommodating the above needs. Paper tubes,
which have a diameter corresponding roughly to the diameter of the denomination of
coin to be placed therein, while being inexpensive to manufacture, are not conducive
to automated wrapping. At the other end of the spectrum, plastic and foil wrappers,
as exemplified by U.S. Patent No. 3,799,428 issued March 26, 1974 to Lamming, provide
many user oriented features, such as indicia which communicates the denomination and
value to the end user, and perforations for ease of coin removal. However, the plastic
and foil construction requires expensive manufacturing processes. Many other wrappers
attempt to provide an optimum coin package, such as U.S. Patent No. 4,546,875 issued
October 15, 1985 to Zweber which discloses a coin wrapping paper having a releasable
adhesive on one side. The length of a particular paper roll is selected to be slightly
longer than the length of a selected coin stack, and it is preferable to encompass
the coin stack two or three times to provide a sturdy roll. The wrapping paper provides
no indicia for the user, but is easily unrolled for coin removal and relatively inexpensive
to manufacture. U.S. Patent No. 673,373 issued April 30, 1901 to Youmans discloses
a paper wrapper which has a pair of openings positioned to coincide with a printed
denomination and value determined by the circumference of the particular denomination
being wrapped. Different denominations and values are printed in a spaced apart relationship
at distances corresponding to the differences in the circumferential measurements
of the coins indicated by the respective printed numbers. However, no attempt is made
to optimize the amount of paper used to roll a stack of coins, nor is automation contemplated.
U.S. Patent No. 4,674,260 issued June 23, 1987 to Rasmussen et al. provides a coin
wrapping mechanism with a unique wrapping material feed portion which minimizes wrapping
material usage. The wrapping material is fed upwardly into a wrapping cylinder in
a direction perpendicular to the rolling movement of the coin stack. This feeding
method allows the wrapping material to be selectively cut to fit the length of the
stack of coins to be wrapped. However, there is no mention of providing a wrapping
material which communicates information to the end user regarding the denomination
or value of coins in a wrapped stack.
[0007] The present invention is directed to overcoming one or more of the problems listed
above.
SUMMARY OF THE INVENTION
[0008] It is the primary object of the present invention to provide a coin wrapper for use
in an automatic wrapping machine which automatically indicates the value and denomination
of coins wrapped therein.
[0009] It is an important object of the present invention to provide a method for minimizing
the amount of wrapping material used for selected denominations and values of coin.
[0010] It is another object of the present invention to provide a coin wrapper which is
inexpensive to manufacture.
[0011] It is yet another object of the present invention to provide a coin wrapper which
wraps coins of varying denominations.
[0012] It is still another object of the present invention to provide information at a glance
concerning the value and denomination of coins within a wrapper.
[0013] It is a further object of the present invention to provide a coin wrapper from which
coins are easily removed without striking or the use of tools.
[0014] In accordance with one aspect of the present invention, there is provided a wrapper
for wrapping a stack of coins, which includes a flexible substrate having a width
and a length and having a coin contacting side and an outer side. A means, such as
adhesive, secures the substrate about the stack of coins. A reference line is formed
along the length of the substrate, and is viewable from the outer side. Indicia is
arranged in lines along the length of the substrate, and is viewable from the outer
side. Each of the lines of indicia provide information about a respective coin stack
having a predetermined circumferential measurement and being spaced from the reference
line by a distance correlative to the circumferential measurement of the respective
coin stack.
[0015] Preferably, there is provided a means for feeding a selected length of wrapping material
in a direction perpendicular to the direction of the rolling movement of the coin
stack and parallel to the longitudinal axis of the coin stack. The feeding means includes
means for adjusting the selected length to permit the wrapping of coin stacks having
different lengths.
[0016] In accordance with another aspect of the present invention, there is provided a method
for wrapping a stack of coins. The method includes feeding a selected length of wrapping
material slightly longer than the length of the stack of coins onto a wrapping surface.
The wrapping material has a reference line and indicia arranged in lines along its
length in the direction of feed. Each of the lines of indicia provide information
about a respective coin stack having a predetermined circumferential measurement and
being spaced from the reference line by a distance correlative to the circumferential
measurement of the respective coin stack. The stack of coins is rolled in a direction
perpendicular to the direction of the feeding movement of the wrapping material, and
the length of wrapping material is cut off of a continuous wrapping material supply
roll is advance of the rolling of the stack of coins over the selected length.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] Referring initially to Fig. 1, the wrapper 10 is made of a flexible substrate 12,
such as paper or plastic, which allows the wrapper 10 to encase a stack of coins.
A stack of coins is wrapped along the width of the coin contacting side 14 of the
substrate 12 from a leading edge 16 to a trailing edge 18. To secure the substrate
12 about a stack of coins, the coin contacting side 14 has selected portion coated
with adhesive. The type of adhesive used and the preferable locations of the adhesive
will be discussed in greater detail in conjunction with the method of operation of
the wrapping mechanism shown in Fig. 3.
[0020] To provide information concerning the denomination and value of coins within a wrapped
coin stack, a reference line 20 and rows of indicia 22 are arranged along the length
of the substrate 12. The reference line 20 and indicia 22 are viewable from the outer
side 24 of the substrate 12, so that after the substrate 12 is wrapped about a stack
of coins the reference line 20 and at least some of the indicia 22 may be easily seen.
The reference line 20 is positioned along the trailing edge 18, and is preferably
bold or otherwise easily discernable. Each row of indicia 22 is generally parallel
to the reference line, and is spaced from the reference line 20 by a distance correlative
to the circumferential measurement of the coin stack about which the indicia provides
information. As shown in Fig. 1, the bottom of the first row of indicia 22a is closest
to the reference line 20, so that the distance therebetween is approximately equal
to the circumferential measurement of the smallest coin to be wrapped by the wrapper
10. Likewise, the bottom of the last row of indicia 22g is furthest from the reference
line 20, so that the distance therebetween is approximately equal to the circumferential
measurement of the largest coin to be wrapped by the wrapper 10. As the substrate
12 is wrapped about a stack of coins, the reference line 20 underscores the row of
indicia 22 which provides information about the wrapped stack of coins, as shown in
Fig. 2.
[0021] The indicia 22 on the illustrated wrapper 10 contains information concerning U.S.
currency, so each row of indicia 22a-22g is spaced from the reference line 20 by a
distance approximately equal to the circumferential measurement of the respective
U.S. coins. These distances are as follows: 2.215 inches for dimes, 2.356 inches for
pennies, 2.623 inches for nickels, 3.000 inches for quarters, 3.277 inches for "Susan
B. Anthony" dollars, 3.786 inches for half dollars, and 4.712 inches for "Eisenhower"
dollars. The indicia 22 provides information concerning the denomination and value
of the U.S. coins. For instance, the first row of indicia 22a contains the indicia
"$5 DIMES" repeated along the length of the substrate 12. Therefore, when a stack
of dimes having a total value of five dollars is wrapped, the reference line 20 underscores
the first row of indicia 22a to communicate to the end user that there are five dollars
of dimes, or fifty dimes, wrapped therein. As an aid to the end user, an arrow 26
followed by the words "READ VALUE HERE" appears beneath the reference line 20. This
further directs the users attention to the row of indicia 22 for quick ascertainment
of the value and denomination of the coins within the wrapper 10.
[0022] The words or symbols in each row are repeated along the length of the substrate 12,
so that the wrapper 10 can be used to wrap coin stacks of varying lengths. As mentioned
in the "Background" section, many businesses provide coin stacks of various lengths.
Therefore, at least one set of words and symbols in each row of indicia 22 are discernable
on any of the various lengths. Moreover, the words and symbols may denote more than
one value for a particular denomination. In this case, both sets of words and symbols
are discernable on any of the various lengths. For instance, banks, which usually
provide only full wraps of quarters, would use indicia similar to "... $10 QUARTERS
$10 QUARTERS ...." The symbol "$10" and the word "QUARTERS" should appear at least
once on every wrap. Alternatively, casinos, which provide half and full wraps of quarters,
would use indicia similar to "... $10 QUARTERS $5 QUARTERS ...." In this case, the
symbols "$10" and "$5" and the word "QUARTERS" appear at least once on every wrap.
To further communicate the actual value of quarters using this type of indicia, a
circle may be placed around the proper symbol, $5 or $10, after the stack is wrapped.
[0023] Color standards provide information "at a glance", and may be used instead of or
in conjunction with words or symbols in the rows of indicia 22. For instance, the
color green designates dimes, and the color red designates pennies. Therefore, the
reference line 20 underscores a green row of indicia when the wrapper 10 contains
dimes, and underscores a red row of indicia when the wrapper 10 contains pennies.
End users obtain information quickly and easily by glancing at the underscored color,
thus improving efficiency and reducing the possibility of selecting the wrong coin
roll.
[0024] Preferably, the substrate 12 is opaque and covers rows of indicia which provide information
about coin stacks having circumferential measurements which are larger than the circumferential
measurement of the wrapped coin stack. A paper substrate having the reference line
and indicia printed thereon produces an opaque and inexpensive wrapper. This type
of wrapper 10 is preferable to a clear plastic wrapper because fewer rows of indicia
22 are visible to the user of the wrapped stacks. As Fig. 2 shows, the wrapped stack
28 contains nickels, since the reference line 20 underscores the row of indicia 22c
which designates nickels. The rows of indicia 22d-22g, which designate coins having
larger circumferences, are covered by the substrate 12. Therefore, only three rows
of indicia 22a-22c are visible to the user.
[0025] To minimize the amount of wrapping material used to wrap coin stacks of varying lengths,
the length of the substrate 12 is adjusted according to the length of the coin stack
to be wrapped. A coin wrapping device 30, shown in Fig. 3, utilizes a method for adjusting
the length of the wrapping material. The substrate 12 is withdrawn from a supply roll
32 by a pair of "three-dimensional" sprocket belts 34 meshing with two corresponding
rows of sprocket holes 36,38 in the substrate 12. A "three-dimensional" sprocket belt
is a commerically available item comprising a flexible metal cable having polymeric
sprockets fastened to the cable at equal intervals along the length thereof. Each
sprocket has four lugs projecting therefrom at 90° intervals around the axis of the
cable. Each of the sprocket belts 34 is trained around a set of six sprocket wheels
39-44, with the wheel 39 being driven by an electric drive motor 46. The motor and
sprocket arrangement drives the substrate upwardly onto a wrapping surface 48.
[0026] Preferably, the coin contacting side 14 of the substrate 12 is coated with a pressure-sensitive,
releasable adhesive, such as the adhesives disclosed in U.S. Patent No. 4,418,120
as having good tack and shear properties, but low peel adhesion to stainless steel.
The adhesives adheres quickly to the outer surface of a stack of coins, and possesses
sufficient shear strength to hold the stack of coins together during handling, and
yet demonstrates a peel adhesion low enough to permit the substrate 12 to be readily
peeled off of the coin stack without leaving any substantial residue of adhesive on
the coins. The adhesive coating is preferably continuous along the full length of
the coin contacting side 14, and across the full width except for the strips which
contain the rows of sprocket holes 36,38, which may be left uncoated to facilitate
punching of the sprocket holes. This type of adhesively backed substrate can be substantially
equal to the length of the coin stack, and need be no more than about 3 millimeters
longer than the coin stack, to hold the coins within the wrapper 10.
[0027] The substrate 12 is fed into the wrapping mechanism and onto the wrapping surface
48 in a direction perpendicular to the direction of rolling movement of the coin stack
during wrapping (e.g., parallel to the axis of the coin stack). There is no need to
provide extra lengths of paper at opposite ends of the coin stack for "crimping" as
is required with conventional wrappers, because the adhesive coating on the substrate
12 obviates the crimping operation. However, to allow for variations in coin thickness
due to wear and manufacturing tolerances, the length of the substrate 12 which is
fed onto the wrapping surface 48 is selected to be slightly longer than the stack
of coins to be wrapped. Since crimping requires about 1.5 centimeters of additional
length of each end of the coin stack, a significantly greater amount of material is
required to wrap each coin stack. During the wrapping of the coin stack, a knife,
or similar cutting means, cuts the selected length L of substrate 12 across its width
along a cutting line 49. Preferably, the knife is located on the leading side of the
coin stack so that the substrate 12 is cut ahead of the coin stack, thereby detaching
the selected length of substrate 12 from the supply roll so that the selected length
can be wrapped around the coin stack as the stack is rolled along the adhesively coated
coin contacting surface 14 of the substrate 12.
[0028] The arrangement of the reference line 20 and the rows of indicia 22 on the substrate
12 allow the substrate to be cut at the optimum length to fit a stack of coins, while
providing accurate information regarding the coins within the wrapper 10. Therefore,
cutting the substrate 12 to be substantially equal to the length of the coin stack,
as described above, is conducive to automated wrapping.
[0029] To minimize the amount of wrapping material used to wrap coin stacks of varying sizes,
the width of the substrate 12 is optimized. If the coin contacting side 14 of the
substrate is coated with a pressure-sensitive, releasable adhesive, the width of the
wrapper 10 is selected to be about 1.5 times the circumferential measurement of the
largest coin to be wrapped. For instance, U.S. currency ranges from a dime having
a circumferential measurement of 2.215 inches to an "Eisenhower" dollar having a circumferential
measurement of 4.712 inches. A substrate 12 having a width of 6.500 inches produces
1.4 revolutions about the "Eisenhower" dollar, and produces 2.9 revolutions about
the dime. This width provides adequate support for coins of all denominations within
the U.S. currency system. However, the vast majority of coins in circulation are dimes,
pennies, nickels and quarters. Therefore, the amount of wrapping material is further
minimized by providing a roll of wrapping material having a width of 4.500 inches.
The material is wide enough to adequately secure quarters and all other smaller coins.
