Definitions
- the manufacturer must either consume the entire roll of material in a single manufacturing operation, which is typically unlikely, or must devise a method to store the unused portion of the roll and any unused cut portions of the roll, which is often times both time consuming and inefficient.
- orthotic and prosthetic devices can be manufactured from different types of raw materials in different dimensions (e.g., thickness)
- a manufacturer may be using more than one roll of material at any given time.
- These multi-raw-material manufacturing processes compound the problem of storing and further dispensing of the unused portions of raw materials.
- the large amounts of unused raw material often times consisting of relatively large and bulky roles measuring many feet in length, results in either cluttered workspaces that can be dangerous, or the consumption of additional warehousing space that is expensive and undesirable.
- the unused portions of material that are no longer connected to the raw-material roll present their own unique storage and further dispensing challenges. More specifically, as portions of material are cut from the large continuous roll of material during the manufacturing process, not all of the cut material is consumed in the immediate manufacturing process, and must then be stored for future use or discarded as scrap. This too is inefficient and undesirable. Because of the relatively large number of different raw materials used to manufacture orthotic devices, storing and retrieving the smaller portions of material can be both time and space consuming and inefficient. For example, when a manufacturer requires a smaller portion of a particular material, the manufacturer must search through numerous pieces and types of materials to find the desired material in the desired size. The inefficiency associated with storing various unused cut portions of material results in increased manufacturing costs, which is undesirable.

Abstract
A dispensing device having a wheel that is made up of a plurality of independent strips of a first material rolled end-to-end and concentrically around a central hub, wherein the end portions of end-to-end adjacent strips are not connected; a housing that houses the wheel; and a dispensing opening through which the strips exit the housing upon being unrolled from the wheel.
Description
- It is well known to manufacture devices having utility in the orthotic prosthetic, podiatric, and pedorthic industry.
- It is common for taw materials used in manufacturing these devices to be shipped in large continuous rolls, often times many feet in length. Because these rolls are relatively large, they are awkward to handle and often create unnecessary shipping expense due to weight and dimensional shipping charges.
- During the manufacturing process, the manufacturer must either consume the entire roll of material in a single manufacturing operation, which is typically unlikely, or must devise a method to store the unused portion of the roll and any unused cut portions of the roll, which is often times both time consuming and inefficient. As a non-limiting example, because orthotic and prosthetic devices can be manufactured from different types of raw materials in different dimensions (e.g., thickness), a manufacturer may be using more than one roll of material at any given time. These multi-raw-material manufacturing processes compound the problem of storing and further dispensing of the unused portions of raw materials. Unfortunately, the large amounts of unused raw material, often times consisting of relatively large and bulky roles measuring many feet in length, results in either cluttered workspaces that can be dangerous, or the consumption of additional warehousing space that is expensive and undesirable.
- Further, the unused portions of material that are no longer connected to the raw-material roll present their own unique storage and further dispensing challenges. More specifically, as portions of material are cut from the large continuous roll of material during the manufacturing process, not all of the cut material is consumed in the immediate manufacturing process, and must then be stored for future use or discarded as scrap. This too is inefficient and undesirable. Because of the relatively large number of different raw materials used to manufacture orthotic devices, storing and retrieving the smaller portions of material can be both time and space consuming and inefficient. For example, when a manufacturer requires a smaller portion of a particular material, the manufacturer must search through numerous pieces and types of materials to find the desired material in the desired size. The inefficiency associated with storing various unused cut portions of material results in increased manufacturing costs, which is undesirable.
- Therefore a need exists in the art to improve these known manufacturing inefficiencies.

And when the appropriate amount ofsheets 26 are finally wrapped onto the sheet-roll hub 24,second material 28 is then wound onto the perimeter ofsheet roll 18 one or two more times in older to securesheets 26. - In another embodiment,
sheet roll 18 can be manufactured by using a butt-welding process. In an embodiment, “butt welding” can be understood as describing a process that can involve heating the ends of two separate sheets and fusing them together; the fused sheets then form one continuous sheet. Using this general method, the end portions offull sheets 26 are first joined together using cement, heat fusion, or both. Then, the cemented or heat-fusedsheets 26 are rolled up around a sheet-roll hub 24 and finally secured withsecond material 28 on the outer perimeter ofsheet roll 18. - In an embodiment, a plurality of

enclosing the wheel in a housing that has a dispensing opening through which a strip can exit the housing upon being unrolled from the wheel.
9. The method of claim 8 , wherein the plurality of sheets are joined together via butt welding.
10. The method of claim 8 , wherein the rolled up sheets that are radially adjacent to one another relative to the sheet-roll hub, are at least partially separated by a second material.
11. The method of claim 10 , wherein the second material is a film.
12. A dispensing device comprising:
a wheel that is made up of a plurality of independent strips of a first material rolled substantially end-to-end and concentrically around a central hub, wherein the end portions of end-to-end adjacent strips are connected with cement, heat fusion, or both;
a housing that houses the wheel; and
a dispensing opening through which the strips exit the housing upon being unrolled from the wheel.
13. The dispensing device of claim 12 , wherein the end portions of end-to-end adjacent strips are not connected but are substantially touching.
14. The dispensing device of claim 12 , wherein the strips of material that are separated from one another in a direction radial to the central hub and are at least partially separated by a second material.
15. The dispensing device of claim 14 , wherein the second material is a plastic film.
16. The dispensing device of claim 12 , wherein the strips of a first material are foam strips having a width ranging from about 4 to about 6 inches.
17. The dispensing device of claim 16 , wherein the strips of material that are separated from one another in a direction radial to the central hub and are at least partially separated by a second material that is a plastic film.
18. The dispensing device of claim 12 , wherein a plurality of end-to-end strip lengths creates a repeating strip-length pattern.
19. A dispensing device comprising:
a wheel that is made up of a plurality of independent foam strips of a first material rolled end-to-end and concentrically around a central hub, the strips having a width ranging from about 4 to about 6 inches, the end portions of end-to-end adjacent strips not connected but substantially touching, the strips of material being separated from one another in a direction radial to the central hub and at least partially separated by a second film material;
a repeating strip-length pattern within the wheel that results from a plurality of end-to-end strip lengths;
a housing that houses the wheel; and
a dispensing opening through which the foam strips exit the housing upon being unrolled from the wheel.
