The present invention relates, in general, to a paper roll cushion for protecting paper rolls from unwanted damages, and, in particular, to a paper roll cushion that is multi-layered and provides protection for transporters of industrial paper rolls.
In the paper roll transportation industry, paper rolls are big, heavy, and expensive. Usually, paper rolls are transported in bulk carriers. For example, paper rolls can be loaded into train cars, shipping containers or vessels. One of the major problems of transporting paper rolls in bulk, would be paper rolls can be easily damaged by physical contact, exposure to moisture, dirt, contaminants, chemicals or odors.
Moreover, paper rolls are very sensitive to debris or objects inside the containers that may puncture or tear through the protective material enclosing the paper roll. When a paper roll is damaged during transport, such as gouging the side or surface of the paper roll, in some instances, the damaged side portion of the roll may need to be removed, in order to salvage the undamaged portion of the paper roll. This would then lead to an increase in waste of materials and reduction in the value of the remaining paper roll. If the owner chooses to not cut the portion of the damaged roll, but instead chooses to unroll it, it would still cost time and money to remove the damaged portion of the paper roll. In some instances, damage that has affected the roundness of the paper roll will require unrolling and re-rolling the paper roll, in order to provide a paper roll that can reliably be used in machinery, such as printing presses, or other processing equipment that must predictably feed the rolled material for processing.
Therefore, there is a need for an easily placed and repeatably adjustable cushion that can preserve the integrity of paper rolls being shipped within a transport container or vessel. Such device should be easily manufactured, low cost, reusable, and capable of being refreshed if damaged or exposed to contamination. The problem is addressed by providing easily placed cushions, that can be customized to provide additional cushioning to the product as it is being loaded into the transport container or vessel. Moreover, it should be easily adjusted to conform to the size needed and easily reusable.
Certain deficiencies of the prior art may be overcome by the provision of one or more embodiments of the paper roll cushion. These and other advantages, aspects, and novel features of the claimed invention, as well as details of illustrative aspects thereof, will be more fully understood from the following description and figures. A deployable paper roll cushion is provided and comprises, a top layer having an elongated raised member composed of a cushion material; a bottom layer having a composition composed of ferromagnetic material which is layered to a rear face of the top layer; and a wrap layer in which an exposed area of the top layer and an exposed area of the bottom layer are covered, and a front face of the top layer receives a downward force from a paper roll while the paper roll is in contact with the wrap layer.
