Private companies, public entities and users in general have the need to classify and archive the documents they handle on a daily basis. The documents are written on sheets of paper that usually have a standard format in each country, either folio or DIN A3 format, DIN A4, DIN AS, or the US exclusive, and another one proprietary from Canada etc., being the Anglo-Saxon folio or the DIN A4 the two most used worldwide to bind and to archive documents.

Despite finding ourselves in an era of information via the Internet, the need to orderly archiving business documents, - contracts, reports, databases etc., has not declined. Likewise, in the public sector, - courts, ministries, etc. - this need for classification, sorting and archiving has multiplied in a few years.

Of course, individuals, students, self-employed professionals, etc., also have to a greater or lesser extent need to keep their information orderly.

In order to be able to deepen into the description of the invention, it is important to distinguish between piecing together some notes, papers or documents with a thin wire that takes an elongated and rounded form at its ends, known internationally by clip, which is usually done to gather a few sheets, and another thing is what our invention really intends, which is an action of greater importance, since its objective is to provide the market with a novel system, more professional and technological better than the one that is currently being used, that allows for the binding of documents without damaging them and allowing an easy and at will subsequent individual removal of the sheets that compose the bound set.

This requirement to classify and file documents has been carried out in recent years and even today, in three main ways:

• The first way of filing (A), is with a binding system for punched paper sheets, that allows later to undo the binding and thus to extract any document that we want from among all the other pages that are bound with it, being all of them previously punched on the left side, with all the sheets usually bound in a ring binder or in bindings made with two pieces usually metallic, one in the form of a sheet having at its ends the shape of a hairpin and the other is a sheet which leaves the ends of said hairpin caught. This system is internationally known as Fastener system.
• The second way of classifying and filing papers (B), rather than of binding, it is of filing, and it is a system that does not require punching the sheets, since it consists of putting each of the sheets that make up the set, inside transparent covers that already carry a standard punching in their left side.
• The third form of binding (C), is very restrictive and consists of a fixed system that does not allow the removal of any page that compose the set, since this type of binding is intended to be permanent, and consists of stapling, or spiral ringing, or fusing, or sewing, or gluing of the left edge of a group of sheets; this third system is more suitable for binding reports or studies that are to be presented and delivered to others, and is not usually used for the archiving of own documentation, that usually has the requirement of occasional removal of some pages, that with this system would need to be de-stapled, removed from the spiral or the spine glued or sewn, destroying the set as a whole.

In the fixed system binding (C), which does not allow for the removal of the pages, because of the staple, or because of the spiral ringing, or the spine fusing, is in itself a serious problem, since any page among the group of bound sheets cannot be removed without breaking or undoing the system, or to prevent this, It is necessary to tear the sheet somewhere, making it impossible to return it to the position in which it was without damage.

This system is dedicated almost exclusively to report elaboration and delivery, but without an archiving purpose and without the possibility of later use of individual pages since they are all forever bound to each other by the fixed binding system.

Binding requiring a plastic sheath (B) in which the document is introduced in, is nowadays widely used for filing papers that can not be damaged with punches and also those that at any given time have to be extracted from the folder for individual use, such as photocopying or filing them in another folder.

The binding by punching system (A), is not fixed and has been done in two ways; the most frequent one is to punch holes on the left side of the sheets to be bound by means of a manual or automatic device and insert these, by the punched round or oval holes, into a ring folder or in bindings made with pieces of the type mentioned before, made by two pieces, base and compressor, internationally known as Fastener, which entails several drawbacks.

Punching two or more holes on the left side of a sheet of paper is damage to the document that we cannot always afford, either for functional or aesthetic reasons.

• b) If the binding is made with a piece of the type of the two piece prong, the visibility of a strip of the margin on the left hand side of all the pages, of approximately 2 cm, is lost and the reading is impeded if those few centimeters of text area have been covered.
• e) It is even worse if we have to make frequent consultations of the bound documentation with the two piece prong system, internationally known as Fastener, since these usually cause the tearing or cutting of the paper sheets at the holes and the inability to be repaired, thus leaving loose sheets within the set of sheets.

To avoid these inconvenients, paper damage and loss of vision of the left side strip of the sheets, the other means of filing, is to put each folio in a transparent sheath (B), which negatively causes an unnecessary bulging of the archived document set, because the thickness of each sheet, which is inserted inside each sheath of two transparent faces, is now tripled.

Likewise, a document set bound in transparent covers implies a high cost.

This invention seeks to solve the need for binding without the use of transparent covers and without applying mutilating systems of punching or stapling. Even more, our invention is of complementary use to any other removable binding system like the one we pointed to of the two pronged binding system, known internationally as Fastener system.

Our invention consists in the application of an attachable element to the paper sheet, namely an already punched and potentially removable adhesive strip, to be fixed in the edges of pages or other page format and thus allow binding without having produced to said sheets of paper no damage whatsoever.

Our invention is ambitious and allows for the manual attachment of the strip or tape to the side of the sheet of paper; also the coupling and set can be semi-manual, and this with the aid of a mechanical device or coupling tool that achieves the adhesion of the tape or strip to the side of the sheet; and finally, the mechanical use of setting and fixing the tape or strip to the side of the paper sheet when this tape is affixed or stripped to the folio simultaneously to the realization of any type of printing in a printing machine, xerography, reprography, photocopying, thermo setting, etc.

The invention consists of an individual element (1) attachable to sheets of paper to facilitate binding, composed of a strip of thin and ductile material, whether synthetic, natural or any other type of material, which is served in two formats, in reel or in strip, than can be set and fixed on the left hand side of a folio or sheet of paper (5), said sheet being adhered to the right-hand side of the individual element (1), not necessarily permanently, as said adhesion can be removed without difficulty at the will of the user.

This individual element must have a certain width which allows for a penetration or a perforation (4), which should usually be pre-made, although not necessarily, located on the left hand side of the strip or tape, adjoining and attached as a single body with the right hand side of the strip which is coated with an adhesive (3), which is covered by a thin film or a film (2) which is to be disposed of at the time of the setting and fixing on the sheet (5), by means of the adhesive right hand part (3) of the individual element (1).

The format of the individual element (1) should have the length and width dimension of the size of the folio or sheet (5) to be attached and affixed to, although in the ribbon format on reel, it could exceed it and be later cut, and a width (1) which allows to maintain on its left hand side a portion with the perforation (4) and attached to this left hand side but on its right hand side, an adhesive band (3) covered by a very thin film or protective film (2).

The individual strip-shaped element (1), shown, allows the setting and manual fixing thereof to the sheet (5) directly.

The individual strip-shaped element (1) may be grouped into a cartridge (9), which will allow its insertion and use into a printing or reprographic machine so the individual fastening of the strips to the sheets of paper can happen in a fast way, through passes.

The passing of the slider (8) tears the very thin film or protective film 2 and the left hand side portion of the sheet (5) is adhered to the adhesive right hand side (3) of the strip.

The individual strip-shaped element (1) will achieve the greatest efficiency if it is used technologically and industrially and this basically making use of a cartridge or the like, which is coupled to a printing, photocopying or reprographic machine where when the sheets (5) are ejected from the machine after printing or copying, will already be had the strip (1) adhered, allowing for a direct binding action.

The individual roll-shaped element has a structure similar to the strip format, although most possibly the latter film part (2) will be dispensable if the attachment of the paper sheet to the element is made with a suitable tool or machine.

The individual roll-shaped element is suitable for insertion into a semi-manual tool machine such as that shown in Figure 6, which at its end (7) has a blade which would cut the end of the tape from the roll after the tape has been fixed on to the sheet (5).

However, the tape itself could already be marked with a stitch line, easily cut or self-cut, at the end of its length, this mark coinciding with the longitudinal dimension of the sheet, and thus, after the coupling of the Individual element to the sheet, with a slight pull, the tape will be teared off, leaving the tool available for the next use.

Both formats, of strip and ribbon on reel perfect to be the innovative and technological component in any semiautomatic machine or automatic machine for printing, photocopying or reprography, regardless of its size and characteristics in such a way that simultaneously to the printing, if selected by the user, the sheet (5) will be automatically set and fixed to the individual element (1) in strip format, leaving that printed sheet through the ejection tray of the machine with the strip already set, said strip (1) being cut to the same length as that of the sheet (5), when the machine exits the document being reproduced or printed.
