Abstract
An endboard for supporting a roll of material is provided. The endboard consists of a substantially rigid member that is sized and shaped to receive and support the roll of material. The endboard is molded from a mixture of plastic and sawdust. The combination of plastic and sawdust provides improved loading bearing strength and allows for support of heavy rolls of material without requiring the roll to support itself on its face. The endboard design thus prevents damage to the rolled material stored in horizontal fashion. In a preferred embodiment, the endboard has a series of elongated substantially parallel recessed portions that are vertically aligned and at least partially define vertical ribbed portions. The recessed portions and ribbed portions thus reduce the amount of material needed for construction of the endboards, while maintaining the structural integrity thereof.
Description
- The present application is based on and claims priority to U.S. Provisional Application Ser. No. 60/477,832, filed on Jun. 12, 2003.
- The present invention relates to a roll end support for packaging rolls of material. More particularly, the present invention is directed to a molded endboard for supporting a roll of material in horizontal orientation. The endboard is formed of a mixture of plastic and sawdust and has at least one recessed and/or ribbed face to provide structural support and to minimize the cost of construction of the endboard.
- Webs of materials and other types of extruded components are commonly shipped and stored as a roll of material wound around a cardboard, center core. These rolls of materials can be damaged by contact during storage and shipment and, as such, are typically shipped and stored with the center core supported along a horizontal axis. Since these rolls of material are not stackable by themselves, various types of packaging systems have been developed for transport and storage of such rolls.
- Various cradle-type packages have been developed that hold a horizontal roll in place, keep it from rolling, and allow numerous horizontal rolls to be stacked. However, these cradle-type packages typically do not provide adequate support for a heavy roll and often require a heavy roll to support itself on its own face surface. Since the roll of material is typically supported along its face, the face of the roll can be damaged or marred during shipment and storage of the material.
- Various suspension-type packages have been developed that suspend the roll in horizontal fashion from the roll's center core. Suspension-type packaging, however, is typically more expensive and more difficult to use than cradle-type packages. A typical suspension-type packaging system, such as the system shown in U.S. Pat. Nos. 3,489,274 and 3,685,644, utilizes a particle endboard that is typically ½ to 1 inch thick and has a hole cut in the center of the board to accommodate the center core of the roll and a core plug. The endboards are typically square shaped, each side being approximately 1 inch longer than the diameter of the roll to be supported.
- The core plug is passed through a hole in the endboard and into the center core of the roll material to be packaged, such that an endboard and core plug is required for each end of the roll to be supported. Once the pair of endboards are attached to each end of the roll of material to be supported, the endboards can be stacked on top of each other to create a pallet for shipment and storage. Typically, most pallets include a series of metal or plastic straps to hold the pallet in a secure arrangement for shipping and storage.
- It is therefore desirable to overcome the drawbacks of known horizontal roll packaging methods by providing a simple, effective, sturdy and cost-efficient packaging means for packaging and stacking multiple rolls of webs of material in a horizontal orientation. Specifically, it is desirable to provide an inexpensive suspension-type packaging construction that provides adequate support for a horizontally stacked roll, such that the rolled material is not damaged. It is further desirable to provide a packaging construction that is lightweight and that provides for easy maneuvering of the packaged horizontal roll.
- The present invention relates to an endboard and system for packaging a roll of material in a generally horizontal orientation. The endboard is molded from a mixture of plastic and sawdust and comprises a substantially rigid member that is sized and shaped to receive and support the roll of material.
- The endboard has a center hole sized to receive a core plug that couples the endboard to an end of a web of rolled material. The core plug is passed through the hole in the endboard and into the core of the roll of material to be packaged—one endboard/plug assembly for each end of the roll of material. The endboards are typically secured to the roll by strapping.
- The endboard of the present invention is easily and inexpensively manufactured. The combination of plastic and sawdust provides a lightweight endboard that has improved load bearing strength and allows for support of heavy rolls of material without requiring the roll to support itself on its face. The endboard design thus prevents damage to rolled material stored in horizontal fashion.
- In a preferred embodiment, the endboard has a series of elongated substantially parallel recessed portions that are vertically aligned when the endboard is supporting the roll of material. The recessed portions may define vertical ribbed portions. The recessed portions and ribbed portions reduce the amount of material needed for construction of the endboard, while maintaining structural integrity of the endboard.
- The drawings illustrate the best mode presently contemplated of carrying out the invention. In the drawings:
- FIG. 1 is a view of the exterior face of a first embodiment of the endboard of the present invention.
- FIG. 2 is a view of the exterior face of a second embodiment of the endboard of the present invention.
- FIG. 3 is a view of the interior face of either at the endboards shown in FIG. 1 or2.
- FIG. 4 is a perspective view of a first embodiment of the packaging system of the present invention employing the endboard embodiment shown in FIG. 1.
- FIG. 5 is an exploded view of the packaging system shown in FIG. 4.
- In the preferred embodiments of the present invention described in detail below, a roll end support for supporting a roll of material is provided. It should be understood that the drawings and specification are to be considered an exemplification of the principles of the invention, which is more particularly defined in the appended claims. For example, although the figures depict various embodiments of an endboard having a certain shape and construction, it should be understood that the overall shape, size and design of the endboard may vary and yet still fall within the scope of the appended claims.
- The present invention relates to a roll end support for packaging and supporting a roll of material. In the preferred embodiments, the invention comprises a molded endboard formed from a mixture of plastics and wood products. Preferably the endboard is formed from a mixture of recycled plastic and scrap wood products, such as sawdust. Preferably, the endboard is formed from a mixture of sawdust and polyethylene. More preferably, the material used to form the endboard consists of between 40% and 50% by volume of fine sawdust and between 50% and 60% by volume of low-density polyethylene. The fine sawdust can be replaced with either normal or coarse sawdust while operating within the scope of the invention. Likewise, it is contemplated that the low-density polyethylene can be replaced by either high molecular weight polyethylene or ultra high molecular weight polyethylene while operating within the scope of the invention. Typically, low-density polyethylene is recovered from the recycling of paper, milk and juice cartons. Thus, the material used to form the endboard of the present invention is typically recovered from recycled plastic components and the waste materials from wood processing centers.
- The unique make-up and construction of the endboard of the present invention provides several advantages. The combination of sawdust and polyethylene provides a significant amount of structural integrity and strength for an endboard that is relatively small in size. The sawdust and polyethylene further provides a lightweight endboard that is capable of securely supporting a much heavier roll of material.
