, Description:
Technical Field of the invention:
The present invention relates generally to the paper packaging, and more particularly to the packaging paper dispensing apparatus which can expand the packaging paper that can be used to wrap the products to be shipped.
Background of the invention:
The paper dispensing apparatus can be used for dispensing papers for variety of applications which can include the packaging paper, toilet paper, bank notes, and so forth. The paper dispensing apparatus which are used in the packaging industry are highly used to store and dispense the wrapping paper which can think paper, die-cut paper and so forth. The die-cut paper which is used in the packaging of the products can be shipped through various modes and is strong and flexible and is capable of expanding into a three-dimensional honeycomb structure on expansion of the paper by application of pressure is increasingly which is eco-friendly and is biodegradable.
As opposed to the traditional plastic bubble-wrap which is used in packaging industry for cushioning purposes in packaging, protects the articles which are packaged from external forces which are applied while in transit. The three-dimensional honeycomb-shaped expanded die-cut paper provides the similar cushioning effect as well as providing protection to the packaged article, in a more environment-friendly way.
There are several prior arts which discloses the system and apparatus for expansion of the die-cut paper.
CA-3067852-A1: Extensible paper and its use in the production of expanded slit packaging and void fill products.
US20170203866A1: Expansion Apparatus and Method for Producing Interlocking Expanded Slit Sheet Packaging Material

US20180222665A1: Slit Paper Method of Expansion, Shipment and Expansion devices
US20190193366A1: Slit Sheet Tensioning Device
US20190248092A1 by David Paul Goodrich discloses a method and apparatus for dispensing and expanding expandable slit sheet material. The said device for expanding and dispensing expandable slit sheet paper includes a pair of support members for a roll of expandable slit sheet paper. The roll of expandable slit sheet paper has an interior core member and a roll of expandable slit sheet paper wound on said interior core member. The interior core member has an axial length that is greater than the width of said slit sheet paper that is wound on said interior core member and has end regions that extend beyond the roll of expandable slit sheet paper. Pressure means is provided for pressing a first end region against its core support member and applying a frictional rotation resistance to the core member end region. The roll of expandable slit sheet paper is mounted on the device by positioning one end region under the pressure means and in a support relationship with its core support member while the roll of expandable slit sheet paper is inclined with respect to the device. The other end region is then moved into its supported position with its core support member. An adjustable downward pressure is exerted on the paper core end region and causing the paper core end region to be pressed against its support member as the paper is pulled. The downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.
There are several existing system and methods which are used for expansion of the three-dimensional honeycomb shaped die-cut paper or slit paper sheet. Some of the existing apparatus which are used for the purpose expands the die-cut paper sheets by applying pressure on a die-cut paper roll through complex machinery where the apparatus requires lot of parts for its construction and has a high maintenance cost. There are several compact systems which are available for the same purpose which comprises of plurality of mechanical features which aide in applying friction and further involves several physical factors to aide in the process of expansion of die-cut paper sheets. The complex systems which are used for expansion of the die-cut paper requires significant number of smaller components such as nuts and bolts, whose management become inconvenient and may sometimes become problematic. Smaller components further add to the complexity of such systems thereby making the task of loading or unloading a roll of die-cut paper on such systems a tedious job for a packer performing the task. Such complexities in systems may be additionally problematic as packers performing the tasks of loading or unloading are unskilled labor, and may face difficulties in completing the job.
The above-mentioned prior arts and the existing systems have tried to address the issues related to the complexity of the system and method and the inconvenience caused during the said process. However, the scope of the said systems has been limited to applying pressure on paper rolls using pressure mechanisms in paper dispensing systems. Some of the drawbacks of these systems include tedious cleaning and maintenance jobs. The complex systems require plurality of intricate components require further maintenance, preplacement and repair for individual components. In case of failure of a single component, the entire system is required to be sent for services and maintenance.
Another drawback of several existing systems is that they rely heavily on electricity for their functioning. The paper expanding systems commonly known in the art are not yet independent of power supply. In an event of a power cut, a user or an operator is, therefore, unable to make use of such systems. Additionally, diameters of paper rolls loaded in the expansion systems for dispensing may have to be of a predetermined value to be loaded in said system. Therefore, if a paper roll does not have the predetermined value of the diameter, there may be troubles in loading such paper roll onto the expansion system.
Therefore, in order to overcome all the drawbacks of the existing systems there is a need for a system which can expand the die-cut paper for packaging purpose which is an easy to use, economical and reliable system and methods through which the die-cut paper can be expanded.
