Definitions
- the present invention relates to a method of forming a coin roll and a coin wrapping mechanism according to the precharacterizing parts of claims 1 and 5.
- Such a mechanism as known from US-A-3 906 964 comprises a coin stacking device for arranging coins into a stack of a predetermined number of coins.
- the coins are supported by means of a holding rod disposed at the lower end of the stack mechanism.
- the mechanism further comprises a coin wrapping device having a plurality of wrapping rolls which are moveable in a direction for mutually approaching and mutually separating from each other.
- the coin stack is clamped by these rolls so that same impart rotation to the coin stack and a piece of wrapping paper is wrapped around the coin stack.
- Upon completion of wrapping the coin stack is discharged by way of a wrapped coin discharge chute.
- Another important object is to provide an improved method and apparatus for forming and wrapping a coin roll which does not require crimping of the wrapping material at the ends of the coin roll.
- Still another object of this invention is to provide an improved method and apparatus for forming and wrapping a coin roll which can be easily opened.
- a method of wrapping a stack of coins is provided to form a coin roll having a circumference, length and two ends, said method comprising the steps of arranging a predetermined number of coins to form a coin stack, contacting the coin stack with a wrapping material, said wrapping material having a width greater than the circumference of said coin stack, and a length of at least as great as the length of said coin stack, and rotating the coin stack about its axis and pressing said wrapping material against the coin stack, so that the wrapping material being wound around the coin stack forms a coin roll.
- the method is characterized by the steps of contacting the coin stack with a wrapping material coated on the side facing the coin stack with a coin-supporting amount of an effective clean-releasing, pressure-sensitive adhesive, the coin stack being contacted with an adhesive-coated side of wrapping material, rotating the coin stack about its axis with a single motor driven wrapping roller while pressing the wrapping material against the coin stack with said wrapping roller to pass the wrapping material between the wrapping roller and the coin stack while the coin stack is being wrapped with the wrapping material so that the adhesive bonds the wrapping material to the coin stack, said adhesive being located to engage at least the end-most coins in said stack, to securely retain said coin stack within said wrapping material, and subsequently removing said coins from said roll by removing said wrapping material and the adhesive thereon from said coins.
- a coin wrapping mechanism for wrapping coins, said mechanism comprising coin stacking means for forming a coin stack containing a predetermined number of coins, means for supporting the coin stack for rotation about its axis, means for rotating the coin stack about its axis, and pressing wrapping material against a coin stack so that it is wound around it, means for removing the coin stack from the rotating means after the desired length of wrapping material has been wound around the coins.
- Said inventive coin wrapping mechanism is characterized in that said means for rotating includes a single motor driven wrapping roller for rotating the coin stack about its axis and for pressing the wrapping material against the coin stack with a wrapping roller, wherein the wrapping material passes between the wrapping roller and the coin stack while being wrapped around the coin stack, said wrapping material having a coating of a pressure-sensitive releaseable adhesive on the side facing the coin stack so that the adhesive adheres to, and is wound around, the coin stack.
- Figs. 1, 2 and 3 illustrate a coin roll wrapping mechanism in three successive stages of operation.
- a coin stack 10 having a known length and circumference (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 housing 12 by a pair of diametrically opposed pins 13 and 14 fitting into recesses in the outside wall of the tube 11, so that the lower end of the tube can be pivoted between (1) a "load buffer" position (illustrated in Figs.
- 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. US 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. When the shutter opens, the coin stack 10 drops into the buffer tube 11. Alternatively, the desired number of coins can be loaded into the buffer tube 11 by hand.
- 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 Fig. 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.
- 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 of a wrapping roller 21 adjacent the wrapping chamber. Lateral support for the coin stack 10 is provided by a pair of idler rollers 21 a and 21 b 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.
- 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.
- a pressure-sensitive, releasable adhesive 31 such as No. 4351 film tape available from Can-Do Inc., Arlington, Tennessee.
- Other suitable adhesives are those disclosed in US Patent No. 4,418,120 as having good tack and shear properties but low peel adhesion to stainless steel.
- the adhesive should adhere quickly to the outer surface of a stack of coins and have sufficient shear strength to securely retain the coins within the wrapper during handling, and yet had a peel adhesion low enough to be effectively clean-releasing, permitting and wrapping material to be readily peeled off the coil roll without leaving any substantial residue of adhesive on the coins and without tearing the wrapping material.
- 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.
- a resilient rubber or foamed-polymer pad 23 is bonded to the outer surface 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.
- 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 recognised, 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 material.
- 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.
- a shoulder 42 and the support disc 20 also engages the wrapped coin roll and assists in ejecting the coin roll from the wrapping mechanism.
- the spring load on the gate returns the gate to its closed position.
- the roller 21 is fastened to a drive shaft 50 journaled in a support plates 51 cantilevered from the bottom of the housing 12.
- the drive shaft 50 in turn carries a drive pinion 52 which 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 leading 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).
- 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 off the wrapper, whereby the roll of coins is cleanly released.

Description
- The present invention relates to a method of forming a coin roll and a coin wrapping mechanism according to the precharacterizing parts of
claims 1 and 5. - Such a mechanism as known from US-A-3 906 964 comprises a coin stacking device for arranging coins into a stack of a predetermined number of coins. The coins are supported by means of a holding rod disposed at the lower end of the stack mechanism. The mechanism further comprises a coin wrapping device having a plurality of wrapping rolls which are moveable in a direction for mutually approaching and mutually separating from each other. The coin stack is clamped by these rolls so that same impart rotation to the coin stack and a piece of wrapping paper is wrapped around the coin stack. Upon completion of wrapping the coin stack is discharged by way of a wrapped coin discharge chute.
- From EP-A-0 116 808 a method for selectively holding a roll of coins is known using a substrate with a clean-releasing pressure-sensitive adhesive. The wrapper width being smaller than the circumference of the coin roll.
- From US-A-2 985 295 it is known to wrap a roll of retaining rings with an adhesive coated substrate extending throughout the full periphery of said retaining rings.
- From CH-A-59 80 80 it is known that an adhesive is only located on two strips of the inner surface of a flexible substrate.
- From EP-A-0 215 647, falling under Article 54(3) EPC, a method of wrapping a stack of coins is known wherein said coin stack is wrapped with a wrapping material coated on the side facing the coin stack with a coin-supporting amount of an effective clean-releasing pressure-sensitive adhesive. The coin stack is in contact with an adhesive-coated side of said wrapping material. By rotating the coin stack about its axis, while pressing said wrapping material against the coin stack, the adhesive bonds the wrapping material to the coin stack. Said adhesive is located to engage at least the end-most coins in said stack, to securely retain said coin stack within said wrapping material.
- It is an object of the present invention to provide a method and apparatus for forming and wrapping a coin roll which can be easily formed without the use of complex guiding mechanisms to control the wrapping material during the coin-wrapping operation.
- Another important object is to provide an improved method and apparatus for forming and wrapping a coin roll which does not require crimping of the wrapping material at the ends of the coin roll.
- Still another object of this invention is to provide an improved method and apparatus for forming and wrapping a coin roll which can be easily opened.
- According to the present invention, a method of wrapping a stack of coins is provided to form a coin roll having a circumference, length and two ends, said method comprising the steps of arranging a predetermined number of coins to form a coin stack, contacting the coin stack with a wrapping material, said wrapping material having a width greater than the circumference of said coin stack, and a length of at least as great as the length of said coin stack, and rotating the coin stack about its axis and pressing said wrapping material against the coin stack, so that the wrapping material being wound around the coin stack forms a coin roll. The method is characterized by the steps of contacting the coin stack with a wrapping material coated on the side facing the coin stack with a coin-supporting amount of an effective clean-releasing, pressure-sensitive adhesive, the coin stack being contacted with an adhesive-coated side of wrapping material, rotating the coin stack about its axis with a single motor driven wrapping roller while pressing the wrapping material against the coin stack with said wrapping roller to pass the wrapping material between the wrapping roller and the coin stack while the coin stack is being wrapped with the wrapping material so that the adhesive bonds the wrapping material to the coin stack, said adhesive being located to engage at least the end-most coins in said stack, to securely retain said coin stack within said wrapping material, and subsequently removing said coins from said roll by removing said wrapping material and the adhesive thereon from said coins.
- According to a further aspect of the present invention, a coin wrapping mechanism is provided for wrapping coins, said mechanism comprising coin stacking means for forming a coin stack containing a predetermined number of coins, means for supporting the coin stack for rotation about its axis, means for rotating the coin stack about its axis, and pressing wrapping material against a coin stack so that it is wound around it, means for removing the coin stack from the rotating means after the desired length of wrapping material has been wound around the coins. Said inventive coin wrapping mechanism is characterized in that said means for rotating includes a single motor driven wrapping roller for rotating the coin stack about its axis and for pressing the wrapping material against the coin stack with a wrapping roller, wherein the wrapping material passes between the wrapping roller and the coin stack while being wrapped around the coin stack, said wrapping material having a coating of a pressure-sensitive releaseable adhesive on the side facing the coin stack so that the adhesive adheres to, and is wound around, the coin stack.
- An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
- Fig. 1 is a perspective view of a coin wrapping mechanism, in a first stage of its operation, for forming a coin roll embodying the present invention;
- Fig. 2 is a perspective view of the coin wrapping mechanism of Fig. 1 in a second stage of its operation;
- Fig. 3 is a perspective view of the coin wrapping mechanism of Fig. 1 in a third stage of its operation;
- Fig. 4 is a top plan view of the coin wrapping mechanism of Fig. 1;
- Fig. 5 is a side elevation taken generally along line 5-5 in Fig. 4;
- Fig. 6 is a section taken generally along line 6-6 in Fig. 5;
- Fig. 7 is a perspective view of a partially wrapped coin roll; and
- Fig. 8 is a perspective view of a completely wrapped coin roll formed by the mechanism of Fig. 1.
- In 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 circumference (with two ends and two opposite circular sides) is loaded from a buffer tube 11 into a wrapping chamber C formed by ahousing 12. The buffer tube 11 is pivotally supported in the upper portion of thehousing 12 by a pair of diametrically opposedpins shoulder 15 formed by thehousing 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 11 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 of coins accumulated in the buffer tube 11 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. US 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. When the shutter opens, the coin stack 10 drops into the buffer tube 11. Alternatively, the desired number of coins can be loaded into the buffer tube 11 by hand. - In order to pivot the buffer tube 11 to its retracted or "load buffer" position after the coins in the buffer tube have been dropped into the wrapping chamber C, a
rotatable cam 16 with a smoothly rounded leadingedge 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 Fig. 1 and 2). The outer edge of thecam 16 then maintains the tube 11 in its retracted position throughout the wrapping of the coin stack in the wrapping chamber. When thetrailing edge 18 of thecam 16 clears the tube 11, aspring 19 pivots the tube to its advanced or "load buffer" position (illustrated in Fig. 3). The relationship of the rotational movement of thecam 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 of awrapping roller 21 adjacent the wrapping chamber. Lateral support for thecoin stack 10 is provided by a pair of idler rollers 21a and 21b recessed in the walls of the wrapping chamber C, a spring-loadedexit gate 22, and thewrapping roller 21. Thecoin stack 10 is free to rotate about its longitudinal axis while supported in this manner within the wrapping chamber. Thecam 16 is mounted on the top of thewrapping roller 21, which extends slightly above the top of thecoin stack 10. - A sheet of wrapping
material 30, such as a plastic film or paper, is fed between thecoin stack 10 and thewrapping roller 21, either manually or by an automatic sheet feeder. This sheet of wrappingmaterial 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 wrappingmaterial 30, namely the side facing thecoin 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 US 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 surface of a stack of coins and have sufficient shear strength to securely retain the coins within the wrapper during handling, and yet had a peel adhesion low enough to be effectively clean-releasing, permitting and wrapping material to be readily peeled off the coil roll without leaving any substantial residue of 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 thematerial 30. - In order to press the wrapping
material 30 against thecoin stack 10, while simultaneously rotating the coin stack, a resilient rubber or foamed-polymer pad 23 is bonded to the outer surface of thewrapping roller 21. It will be noted that theresilient pad 23 does not extend all the way around the circumference of thewrapping roller 21, thereby forming an "open" angle a within which a new sheet of wrappingmaterial 30 can be inserted into the throat between theroller 21 and thecoin stack 10 in each revolution of the roller. Then when the leading edge of theresilient pad 23 engages the new sheet of wrapping material, thepad 23 presses the leadingedge 32 of the wrappingmaterial 30 against the coin stack. Because of the adhesive coating on the side of the wrappingmaterial 30 facing the coin stack, the wrapping material adheres to the coin stack. - Continued rotation of the
roller 21 and thepad 23 causes the coin stack to rotate because theresilient pad 23 continues to press against the coin stack, through the wrappingmaterial 30. As the coin stack is rotated, the sheet of wrappingmaterial 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 theroller 21 and thecoin stack 10, and continues to be pressed against the coin stack, by theresilient pad 23. Thus, the wrapping material is wound tightly around thecoin stack 10 as the stack is driven by thepad 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 thetrailing edge 33 of the wrapping material overlapping and adhered to the first layer of wrapping material. It will be recognised, however, that the diameter of theroller 21 and/or the circumferential length of thepad 23 can be increased to wrap two or more layers of wrapping material around the stack of coins. If desired, thepad 23 can extend around the entire circumference of theroller 21, with the roller being retracted away from the coin stack during a portion of each revolution to allow a new sheet of wrappingmaterial 30 to be fed into the wrapping mechanism. - The height of the
resilient pad 23 is slightly greater than the height of thecoin stack 10 to ensure that the last coin at both ends of the stack is secured by the adhesive 31 adjacent theside edges - As the trailing edge of the
resilient pad 23 clears thecoin stack 10, rotation of the coin stack ceases. At this point, the sheet of wrappingmaterial 30 has been wound around the entire circumference of thecoin 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 theresilient 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-loadedexit 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, ashoulder 42 and thesupport 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 thegate 22, the spring load on the gate returns the gate to its closed position. - For the purpose of driving the wrapping
roller 21 and thecam 16 andsupport disc 20 attached to the upper and lower ends thereof, theroller 21 is fastened to adrive shaft 50 journaled in asupport plates 51 cantilevered from the bottom of thehousing 12. Thedrive shaft 50 in turn carries adrive pinion 52 which can be driven by any suitable drive means, such as a toothed belt driven by an electric motor. If desired, thedrive 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 leading
edge 32 of the wrappingmaterial 30 contacting thecoin stack 10 along the lengths of the coin stack and the wrapping material. (The surface of the wrappingmaterial 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 trailingedge 33 of the adhesive-coated inside surface of the wrappingmaterial 30 overlaps the outside surface of the leadingedge 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 off the wrapper, whereby the roll of coins is cleanly released.

said wrapping material (30) having a coating of a pressure-sensitive, releasable adhesive (31) on the side facing the coin stack (10) so that the adhesive adheres to, and is wound around, the coin stack (10). - A coin wrapping mechanism as claimed in claim 5 which includes resilient biasing means (23) urging said wrapping material (30) against said coin stack (10) during the winding of said wrapping material (30) around the coin stack (10).
- A coin wrapping mechanism as claimed in claim 5 or 6, which includes means (50,52) for effecting relative movement between said resilient biasing means (23) and said coin stack (10) being rotated about its axis, whereby said wrapping material (30) is wound around the coin stack (10).
- A coin wrapping mechanism as claimed in any of claims 5 to 7 wherein said means for rotating the coin stack (10) comprises a driven wrapping roller (21) having a resilient pad (23) on the outer surface thereof and poisitioned to press against the coin stack (10) so that the coin stack (10) is rotated by frictional engagement with the resilient pad (23) when the wrapping roller (21) is driven.
- A coin wrapping mechanism as claimed in claim 8, wherein said resilient pad (23) extends only partially around the circumference of said wrapping roller (21) so that as the wrapping roller (21) is rotated, a portion of the roller circumference is spaced away from the coin stack (10) to allow (1) removal of the wrapper coin stack (10) from said wrapping roller (21), (2) loading of a new coin stack (10) and (3) insertion of the wrapping material (30) between the wrapping roller (21) and the new coin stack.
- A coin wrapping mechanism as claimed in any of claims 5 to 9 wherein said coin stacking means includes a buffer tube (11) for holding a coin stack (10) directly adjacent said supporting means (20).
- A coin wrapping mechanism as claimed in claim 10, wherein said buffer tube (11) is pivoted for movement between a first position where the lower end of the tube (11) is aligned with said supporting means (20) for loading a stack of coins onto said supporting means, and a second position where the lower end of the tube (11) is closed so the tube (11) can receive a new stack of coins through its upper end.
- A coin wrapping mechanism as claimed in claim 11, which includes cam means (16), mounted for rotation with said wrapping roller (21), for moving said buffer tube (11) from said first position to said second position.
- A coin wrapping mechanism as claimed in any of claims 5 to 12 in which there is provided a wrapping chamber (C) having gate means (22) for permitting the wrapped coin stack (10) to be removed from the wrapping chamber (C) in the direction of rotation of the coin stack rotating means (21).
- A coin wrapping mechanism as claimed in claim 13, wherein said coin stack rotating means (21) includes means (40,41,42) for positively moving the wrapped coin stack (10) through said gate means (22) upon completion of the wrapping step.
