Detailed Description Of Preferred Embodiments While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will be described in detail herein. It should be understood, however, that it is not intended to limit the invention to the particular forms disclosed, but, on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit a~d scope of the invention as defined by the appended claims.
Turning now to the drawings, FIGS. 1, 2 and 3 illustrate a coin roll wrapping mechanism in three successive stages of operation. Referring first to FIG. 1, a coin stack 10 having a known length and circum~erence (with two ends and two opposite circular sides) is loaded from a buffer tube 11 into a wrapping chamber C formed by a housing 12. The buffer tube 11 is pivotally supported in the upper portion of the 14-158/8/sp ~7~ 7 housing 12 by a pair of diametrically opposed pins 13 and 14 fitting into recesses in the outside wall of the tube ll, so that the lower end of the tube can be pivoted between (l) a "load buffer" position (illustrated in FIGS. l and 2) where the bottom of the tube is blocked by a shoulder 15 formed by the housing 12 directly above and adjacent to the wrapping chamber C, and (2) a "load wrapper" position (illustrated in FIG. 3) where the bottom of the tube ll opens directly into the wrapping chamber C. In the "load buffer"
position, the tube 11 receives a pre-counted stack of coins in readiness for the next wrapping operation. In the "load wrapper" position, the stack or coins accumulated in the buffer tube ll is dropped into the ; wrapping chamber C, ready to be wrapped.
; The coin stack 10, which contains a prescribed number of coins of a given denomination, may be formed -;~ by any of a variety of different coin counting and stacking mechanisms, such as the one described in Nakamura et al. U.S. Patent No. 4,515,172. Such stacking mechanisms typically have a shutter which opens each time it is desired to load a new coin stack into the wrapping mechanism. ~hen the shutter opens, the coin stack 10 drops into the buffer tube ll.
Alternatively, the desired number of coins can be loaded into the buffer tube ll by hand.
In order to pivot the buffer tube ll to its 14-158/8/sp .
.
: ' ' . . ' .
retracted or "load bu~fer" position after the coins in the buffer tube have been dropped into the wrapping chamber C, a rotatable cam 16 with a smoothly rounded leading edge 17 engages the outside wall of the tube 11 near the lower end thereof and pushes the lower end of the tube to its retracted position (as shown in FIGS. 1 and 2). The outer edge of the cam 16 then maintains the tube 11 in its retracted position throughout the wrapping of the coin stack in the wrapping chamber.
When the trailing edge 18 of the cam 16 clears the tube 11, a spring 19 pivots the tube to its advanced or "load buffer" position (illustrated in FIG. 3). The relationship of the rotational movement of the cam 16 and the wrapping mechanism will be apparent from the ensuing description.
The stack of coins loaded into the wrapping chamber C rests on a disc 20 extending radially outwardly from the bottom o~ a wrapping roller 21 adjacent the wrapping chamber. Lateral support for the coin stack 10 is provided by a pair of idler rollers 21a and 21b recessed in the walls of the wrapping chamber C, a spring-loaded exit gate 22, and the wrapping roller 21. The coin stack 10 is free to rotate about its longitudinal axis while supported in this manner within the wrapping chamber. The cam 16 is mounted on the top of the wrapping roller 21, which extends slightly above the top of the coin stack 10.
14-15~/8/sp ~ 7 ~7~.1i7 A sheet of wrapping material 30, such as a plastic film or paper, is fed between the coin stack 10 and the wrapping roller 21, either manually or by an automatic sheet feeder. This sheet of wrapping material 30 forms a flexible substrate having a width W greater than the circumference of the roll and a length L at least as great as the length of the roll. One side of this wrapping material 30, namely the side facing the coin stack 10, is coated with a pressure-sensitive~
releasable adhesive 31, such as No. 4351 film tape available from Can-Do Inc., Nashville, Tennessee.
Other suitable adhesives are those disclosed in U.S.
Patent No. 4,418,120 as having good tack and shear properties but low peel adhesion to stainless steel.
That is, the adhesive should adhere quickly to the outer sur~ace of a stack of coins and have sufficient shear strength to securely retain the coins within the wrapper during handling, and yet have a peel adhesion low enough to be effectively clean-releasing, permitting the wrapping material to be readily peeled off the coin roll without leaving any substantial residue Gf adhesive on the coins and without tearing ~ the wrapping material. If desired, the wrapper can be ; re-used. The adhesive coating 31 is preferably continuous along the full length and across the full width of the material 30.
In order to press the wrapping material 30 against 14-158/8/sp "~, , - , , :~ .
: ' :
~7~67 the coin stack 10, while simultaneously rotating the coin stack, a resilient rubber or foamed-polymer pad 23 is bonded to the outer sur~ace of the wrapping roller 21. It will be noted that the resilient pad 23 does not extend all the way around the circumference of the wrapping roller 21, thereby forming an "open" angle a within which a new sheet of wrapping material 30 can be inserted into the throat between the roller 21 and the coin stack 10 in each revolution of the roller. Then when the leading edge of the resilient pad 23 engages the new sheet of wrapping material, the pad 23 presses the leading edge 32 of the wrapping material 30 against the coin stack. Because of the adhesive coating on the side of the wrapping material 30 facing the coin stack, the wrapping material adheres to the coin stack.
Continued rotation of the roller 21 and the pad 23 causes the coin stack to rotate because the resilient pad 23 continues to press against the coin stack, through the wrapping material 30. As the coin stack is rotated, the sheet of wrapping material 30 follows the rotating surface of the stack, both because the wrapping material is adhered to the surface of the stack and because the wrapping material is drawn into the nip between the rolier 21 and the coin stack 10, and continues to be pressed against the coin stack~ by the resilient pad 23. Thus, the wrapping material is ~wound tightly around the coin stack 10 as the stack is 14-158/8/sp ':' 6~
driven by the pad 23.
In the illustrative embodiment, the circumferential length of the pad 23 is only slightly longer than the circumference of the coin stack, so that only one layer of the wrapping material is wound around the major portion of the stack with only the trailing edge 33 of the wrapping material overlapping and adhered to the first layer of wrapping material.
It will be recognized~ however, that the diameter of the roller 21 and/or the circumferential length of the pad 23 can be increased to wrap two or more layers of wrapping material around the stack of coins. If desired, the pad 23 can extend around the entire circumference of the roller 21, with the roller being retracted away from the coin stack during a portion of~
each revolution to allow a new sheet of wrapping material 30 to be fed into the wrapping mechanism.
The height of the resilient pad 23 -is slightly greater than the height of the coin stack 10 to ensure that the last coin at both ends of the stack is secured by the adhesive 31 adjacent the side edges 34 and 35 of the wrapping material. If desired, a small extra length of wrapping material can be folded over the ends of the coin stack, but there is no need for the crimping operation required by present coin wrapping machines, because the coins are retained within the wrapper by the adhesive coating on the wrapping 14-158/8/sp ~' iO

material.
As the trailing edge o~ the resilient pad 23 clears the coin stack 10, rotation of the coin stack ceases. At this point, the sheet of wrapping material 30 has been wound around the entire circumference of the coin stack 10 and releasably bonded thereto. To eject the wrapped coin roll from the wrapping mechanism, a pair of ejector pins 40 and 41 project laterally from the wrapping roller 21 a short distance behind the trailing edge of the resilient pad 23. As these ejector pins 40 and 41 come into engagement with the wrapped coin roll, they push the coin roll against the spring-loaded exit gate 22, thereby pushing the gate open against its spring bias and ejecting the wrapped coin roll through the opened gate. At the same time the ejector pins 40 and 41 engage the coin roll, a shoulder 42 on the support disc 20 also engages the wrapped coin roll and assists in ejecting the coin roll from the wrapping mechanism. After the coin roll has cleared the gate 22, the spring load on the gate returns the gate to its closed position.
For the purpose of driving the wrapping roller 21 and the cam 16 and support disc 20 attached to the upper and lower ends thereof, the roller 21 is fastened to a drive shaft 50 journaled in a support plate 51 cantilevèred from the bottom of the housing 12. The drive shaft 50 in turn carries a drive pinion 52 which 14-158/8/sp : ~ ' ~2~ }~
can be driven by any suitable drive means, such as a toothed belt driven by an electric motor. If desired, the drive shaft 50 could be driven directly by an electric motor.
FIG. 7 illustrates a partially wrapped coin roll, with the adhesive-coated inner surface of the leadiny edge 32 of the wrapping material 30 contacting the coin stack 10 along the lengths of the coin stack and the wrapping material. (The surface of the wrapping material 30 which faces radially toward the coin roll is referred to here as the "inner" surface, while the surface which faces radially away from the coin roll is referred to as the "outer" surface.) In the final wrapped coin roll, shown in FIG. 8, the trailing edge 33 of the adhesive-coated inside surface of the wrapping material 30 overlaps the outside surface of the leading edge 32 and is adhered thereto by the adhesive 31. The adhesive coating along the side edges 34 and 35 of the wrapping material adheres to the coins at the ends of the roll to securely retain those coins in the roll; thus, the adhesive coating proximate the side edges 34 and 35 must contain a coin-supporting - amount of the adhesive 31. Because the adhesive 31 is clean-releasing, the coins are selectively held in the wrapper and can be selectively cleanly released from the wrapper by removing the wrapper by merely peeling ':
14-158/8/sp ~ 7~
off the wrapper, whereby the roll of coins is cleanly released.

As these ejector pins 40 and 41 come into engagement with the wrapped coin roll, they push the coin roll against the spring-loaded exit gate 22, thereby pushing the gate open against its spring bias and ejecting the wrapped coin roll through the opened gate. At the same time the ejector pins 40 and 41 engage the coin roll, a shoulder 42 on the support disc 20 also engages the wrapped coin roll and assists in ejecting the coin roll from the wrapping mechanism. After the coin roll has cleared the gate 22, the spring load on the gate returns the gate to its closed position.
For the purpose of driving the wrapping roller 21 and the cam 16 and support disc 20 attached to the upper and lower ends thereof, the roller 21 is fastened to a drive shaft 50 journaled in a support plate 51 cantilevèred from the bottom of the housing 12. The drive shaft 50 in turn carries a drive pinion 52 which 14-158/8/sp : ~ ' ~2~ }~
can be driven by any suitable drive means, such as a toothed belt driven by an electric motor. If desired, the drive shaft 50 could be driven directly by an electric motor.
FIG. 7 illustrates a partially wrapped coin roll, with the adhesive-coated inner surface of the leadiny edge 32 of the wrapping material 30 contacting the coin stack 10 along the lengths of the coin stack and the wrapping material. (The surface of the wrapping material 30 which faces radially toward the coin roll is referred to here as the "inner" surface, while the surface which faces radially away from the coin roll is referred to as the "outer" surface.) In the final wrapped coin roll, shown in FIG. 8, the trailing edge 33 of the adhesive-coated inside surface of the wrapping material 30 overlaps the outside surface of the leading edge 32 and is adhered thereto by the adhesive 31. The adhesive coating along the side edges 34 and 35 of the wrapping material adheres to the coins at the ends of the roll to securely retain those coins in the roll; thus, the adhesive coating proximate the side edges 34 and 35 must contain a coin-supporting - amount of the adhesive 31. Because the adhesive 31 is clean-releasing, the coins are selectively held in the wrapper and can be selectively cleanly released from the wrapper by removing the wrapper by merely peeling ':
14-158/8/sp ~ 7~
off the wrapper, whereby the roll of coins is cleanly released.
