1. Field of Invention
The present invention relates to document binding and more particularly to an apparatus of forming a gummed member and a method of binding papers of a document by means of the gummed member.
2. Related Art
It is typical to keep important papers (e.g., invoices, receipts, or the like) of a company as records for future reference. However, it is also known that loose papers of a folder tend to be lost. Binders also have similar drawbacks. Thus, the need for improvement of binding papers still exists.
It is therefore an object of the present invention to provide an apparatus of manufacturing a gummed member for document binding, comprising a supply spool with a continuous sheet of base member wound therearound; a support having rollers for guiding the continuous sheet of base member from the supply spool to move along its top; a funnel disposed above the support for depositing adhesive material on the continuous sheet of base member to form a continuous layer of uniform thickness thereon; means disposed at a rear of the support for cooling the continuous sheet of base member and the continuous layer; and means for cutting the continuous sheet of base member and the continuous layer into a plurality of base members having a releasable sheet formed thereon; wherein the releasable sheet is adapted to remove from the base member to expose its gummed member.
It is another object of the present invention to provide a method of binding papers of a document, comprising cutting a rectangular unit out of a base member formed thereon with a releasable sheet having a gummed member; removing the gummed member from the unit by tearing; adhering the gummed member to a spine of a hard cover; placing a plurality of papers on either half portion of an inner surface of the cover; folding the cover to initially position the papers with one sides of the papers engaged with the gummed member; upright holding the cover and inserting same into a slot of a binding device to rest upon a heating element on a bottom of the slot; activating the heating element to melt the gummed member for binding the papers in the cover; and cooling for a predetermined period of time to produce the document.
In one aspect of the present invention the base member is formed of a heat-resistant, transparent plastic material.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to FIGS. 1 to 12, a preferred embodiment of the invention is shown. As shown in
As shown in
As shown in FIGS. 4 to 9, a simple process of binding a document as done in an office is illustrated. First, for example, a pair of scissors is employed to cut a rectangular member 10A including a rectangular gummed member 20A out of the base member 10. Next, the person may remove the gummed member 20A from the member 10A by tearing. Adhere a bottom of the gummed member 20A to the spine 31. Next, fold the cover 30 to initially position a suitable number of papers 40 therein in which one sides of the papers 40 are engaged with the gummed member 20A. Next, hold the cover 30 in an upright position prior to inserting a lower portion thereof into a U-shaped slot of a binding device 50 to rest on a heating element (indicated by dashed lines) on the bottom of the slot. Next, activate the heating element to melt the gummed member 20A for binding the papers 40 in the cover 30. Next, wait for a period of predetermined cooling time to produce a bound document. Finally, remove the bound document from the binding device 50.

Note that the base member 10 is formed of a heat-resistant, transparent plastic material with a small thickness.
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
