Abstract

ABSTRACT OF THE DISCLOSURE

A coin wrapper, suited for use in an automated wrapping mechanism, provides information concerning a coin stack wrapped therein while minimizing the amount of material needed to securely wrap the coin stack. To provide information concerning the denomination and value of coins within a wrapped coin stack, a reference line and rows of indicia are arranged along the length of a flexible substrate. A stack of coins is rolled along the width of the coin contacting side of the substrate which has a coating of adhesive thereon. The length of the substrate which is wrapped about the stack of coins is equal to or slightly greater than the length of the stack of coins, and the width is selected to provide about 1.5 revolutions about the largest diameter coins to be wrapped. Each row of indicia is spaced from the reference line by a distance correlative to the circumferential measurement of a respective coin stack, so that when a stack is wrapped, the reference line underscores the row of indicia which provides information concerning the coins within the wrapper.

Description

20~8~86 .. , PRE-MARRED COIN ~RAPPBR

BACRGROUND OF THE INVENTION

1. Field of th~ Invention This invention relates generally to coin wrappers, and more particularly to coin wrapping paper for denoting the denomination and value of coin~ wrapped therein.

2. Desaription of the ~elAt~d Art Many types of coin wrappers have been or are being used to enclose a plurality of coins for handling purpo6es.
lo 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.

; 15 Presently, businesses which handle large quantities of coins, such as financial in~titutions and casinos, are quite cost ~ensitive. 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 empl4yees' time as it impacts service and overall throughput. ~here~ore, the resulting wrapped coin rolls should convey information quickly, and ~hould easily release coins when needed.

; 25 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.

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 o~ varying value and size. For instan~e, "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 i8 wasted.

Previoua wrapper~ have fallen ~hort of accommodating the above needs. Paper tube~, 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 is ued March 26, 1974 to Lamming, provide many user oriented features, ~uch as indicia which communicates the denomination and value to th3 and 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 i8 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 . . . . ~ .. . . .. .

X~3~8~86 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 number~. However, no attempt is made to optimize the amount of paper u~ed 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 unigue 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 ~electively cut to fit the length of thQ stack of coin~ 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.

The present invention is directed to overcoming one or more of the problems listed above.

., .
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.

, DEBCR;~PTION 2~ TI~E~R~ ODIM~:NT

Referring initially to Fig. 1, the wrapper 10 i8 made of a flexible substrate 12, such as paper or plastic, which allows the wrapper 10 to encase a stack o~ coln~.
A stack of coins is wrapped along the wldth o~ the coin i~ 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 portions coated with adhesive. The type of adhesive used and the pre~erable locations of the adhesive will be discussed in greater detail in : . . .
''~:; , -- ~ - ' . ~

Z6~ 86 con~unction with the method of operation of the wrapping mechanism shown in Fig. 3.

- 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 sub~trate 12 is wrapped about a stack of coin6 the reference line 20 and at least some of the indicia 22 may be easily seen. The reference line 20 i8 positioned along the trailing edge 18, and i~ 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 ~hown in Fig. 1, the bottom of the first row of indicia 22a is closest to the reference llne 20, ~o that the distance therebetween is approximately equal to the circu~ferential measurement of tho smallest coin to be wrapped by the wrapper 10. Likewise, the bottom of the last row of indicia 22g i~ furthest from the reference line 20, 80 that the distancQ 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 ~tack of coins, the reference llne 20 underscores the row o~ lndicia 22 which provides information about the wrapped stack of coins, as shown in Fig. 2.

The indicia 22 on the illustrated wrapper 10 contains information concerning U.S. currency, 80 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. coin6. These distances are as follows: 2.215 inches for dimes, 2.356 inches for pennies, 2.~23 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 provide~
information concerning the denomination and value of tha U.S. coins. For instance, the first row of indicla 22a contain~ the indicia "$5 DIMES'I repeated along the length of the 3ubstrate 12. ~herefora, when a ~tack of - dlmQs having a total value of ~lve dollars i~ wrapped, the reference line 20 under~corQs the first row of indicia 22a to communioate 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 word~ ~READ VALUE HERE~ appears beneath the reference line 20. This further directs the users attention to the row o~ indicia 22 for quick ascertainment of the value and denominatlon of the coln~
wlthin the wrapper 10.

The words or symbols in each row are repeated along the length of the substrate 12, 80 that the wrap~)er 10 can be used to wrap coin stacks of varying len~ths. As mentioned in the "Background" section, many businesses provide coin stacks of variou~ lengths. Therefore, at least one set of words and symbols in each row o~
indicia 22 are discernable on any o~ the varlous lengths. Moreover, the words and symbol~ may denote more than one value for a partlcular denomlnation. In this case, both sets of word~ and symbols are discernable on any of the variou~ 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 "QUARTERSIl should appear at least once on every ,.

.
.

- :.. ~ :~ :
,~

X~8 ~8~i wrap. Alternatively, casinos, which provide half and full wraps of quarters, would use indicia similar to "... $10 QUARTERS $5 QUARTERS ...." In this case, the ~ymbols "$10" and "$5" and the word "QUARTER~" 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.

Color standards provide information "at a glance", and may be used instead of or in con~unction with words or symbols in the row~ of indicia 22. For instance, the color green designates dimes, and the color red -~ designates pennie~. Therefore, the reference line 20 - undQr~cores a green row Or indicia when th2 wrapper 10 contains dime~, and underscores a red row of indicia when the wrapper 10 contain~ pennias. End users obtain ; information quickly and easily by glancing at the underscored color, thus improving efficiency and reducing the possi~illty of ~electing the wrong coin roll.

Preferably, the substrate 12 ~8 opaque and covers row~
o~ indicia which provide information about coin stack~
having circu~farential measurements which are larger than the circum~erential measurement of the wrapped coin stack. A paper substrate having the re~erence line and indicia printed thereon produces an opaque and inexpensive wrapper. Thi~ type of wrapper 10 1 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 dQ~ignates nickels. The rows of indicia 22d-22g, which designate coins having larger circumferences, are covered by the substrate 12.
', . .' ' .: . . .

.

8 ~86 Thèrefore, only three rows of indicia ~2a-22c are visible to the user.

To minimize the amount of wrapping material used to wrap coin stack6 of varying lengths, the length of the substrate 12 i8 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 ~ubstrate 12 is withdrawn from a supply roll 32 by a pair of "three- -lo 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 commercially available item co~prising a flexible metal cable having polymeric sprockets fastened to the cable at equal intervals along the length thereof. Each sprocket has four lug~ pro~ecting therefrom at 90 intQrvals around the axi~ of the cabls. Each of the sprocket belts 34 18 trained around a set of six ~procket wheels 39-44, with the wheel 39 being driven by an electric drive motor 46. The motor and ~procket arrangement drives the ~ubstrate upwardly onto a wrapping surface 48.

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 a~ having good tack and ~hear properties, but low peel adhe~ion to stainles~ steel.
The adhesive 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 o~
adhesive on the coins. The adhesive coating is .: - . ,.. ,.. i.
~: .: . -' - 2~ 8~
. ~

prefQrably 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 hole~. This type of adhesively backed substrate can be substantially egual 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.

~ . .
The substrate 12 i~ fed into the wrapping mechanism and onto the wrapping sur~ace 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 i8 no need to provide extra lengths of paper at opposite end~ of the coin stack for "crimping" as is required with conventional wrappers, because the adhesive coating on the substrate 12 obvlates the crlmplng operatlon. ~owever, to allow for variat1ons in coln thicknes~ due to wear and manufacturing tolerances, the length o~ the substrate 12 which i8 fed onto the wrapping surface 48 is selected to be slightly longer than the etack o~ coin~ to be wrapped. Since crimping require3 about 1.5 centimeters o~ additional length on each end of thQ 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 sub~trate 12 acros~ its width along a cutting line 49. Prererably, the knife is located on the leading side of the coin stack 80 that the ~ubstrate 12 is cut ahead of the coin ~tack, thereby detaching the selected length o~ substrate 12 from the supply roll 80 that the ~elected 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.

Therefora, cutting the substrate 12 to be substantially equal to the length of the coin stack, as described above, is conducivs to automated wrapping.

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 i8 coated with a pressure-sensitive, ; releasable adhesive, the width of the wrapper 10 is selected to be about 1.5 times the circumferentlal measurement of the largQst coin to be wrapped. For instance, U.S. CUrrency range~ ~rom ~ d1mQ havlng a circum~erential measurement of 2.215 inche~ to an "Eisenhower" dollar having a clrcumferential 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.
Thifi width provides adequate support for coins of all denominations within the U.S. currency system. ~owever, ; the vast ma~ority of coins in circulation are dimes, pennies, nickels and quarters. Therefore, the amount of wrapping material is further mlnimized by providlng a roll of wrapping material having a width Or 4.500 inches. The material is wide enough to adequately secure quarters and all other smaller coins.
