Description

Cover for bookbinding, binding procedure and its use

Object of the invention

The object of the invention is a cover comprising cover, back cover and spine for binding of documents, manuals, books and others, by means of the binding elements, a binding procedure with said cover and its use.

Background of the invention

Numerous systems of binding are known, both books, notebooks, manuals and other stationery. Generally these systems incorporate binding elements such as flaps, seams or seams, wires or simply use glues. However, these types of solutions do not collect the sheets in a satisfactory way.

All of them show some disadvantages in their appearance, complexity, utility or use; and also in its cost or assembly.

Although the permanent binding of the press with spine and using glue and / or sewing of the sheets shows a professional-looking finish, it is expensive when carried out essentially in small quantities and does not easily allow a total 180 ° opening and much less a complete opening of 360 ° While the coverings of loose sheets drilled with covers can have several designs: with wire making rings according to GB 8707843, with discs according to US patent 6074152, with plastic rings according to US patent 6270280 or similar. However, these types of bindings have the disadvantage of not being able to be bound with a spine that informs them of their content, of not keeping the sheets together and not providing them with a better final appearance.

SUBSTITUTE SHEET (RULE 26) Although the well-known ring comb binding, both wire and plastic or discs, are practical, light, compact, cheap, they remain flat when they open and allow full 360 ° opening, which is very useful for handling , and keep the content well held without loss of leaves; Their appearance is not yet ideal, since when they are closed and filed on a shelf, they show the rings, which in many occasions can be hooked with other objects and also cannot be labeled with their corresponding title.

In addition, the rings or discs that join the sheets, being unprotected, easily bend or deteriorate since they do not have any type of protection. This problem is even more serious in the corners of the binding, where there are more involuntary knocks or bends, and where the binding system is weaker. In some cases, by folding both the binding rings, they make it difficult to open the document or notebook.

Other types of covers with spine known do not allow the total opening of 360 °, also make it difficult to open even 180 ° or leave the contents of the leaves without full contact with the covers that collect and protect them. In addition, the process of its inclusion in the automation of the covers in the professional binding machines of the market is quite complicated, proving commercially unfeasible and in some cases even impossible.

The cover according to the present invention solves all the above disadvantages and provides an economical system and with a suitable termination.

Description of the invention

The cover according to the present invention comprises cover, back cover and spine for document binding by means of binding elements, and

SUBSTITUTE SHEET (RULE 26) characterized in that it is formed by a sheet comprising at least:

- longitudinal groove essentially located in the central part of the spine, - longitudinal groove of outer fold and longitudinal groove of inner fold of the lid, forming between them a guide surface of spine,

- longitudinal groove of outer fold and longitudinal groove of inner fold of the back cover, forming between them a spine guide surface,

- plurality of pairs of holes on both sides of the longitudinal crease groove inside the lid,

- plurality of pairs of holes on both sides of the longitudinal crease groove inside the back cover; where, when placing the sheet with the document to be bound, both the cover and the back cover are folded respectively along the axes of their longitudinal grooves, while the respective holes are essentially adjacent to the binding edge and receive the binding elements.

The invention also relates to the method of binding with the present cover, where the sheet is folded by its longitudinal groove of inner fold of the lid, holes are drilled forming plurality of pairs of holes on both sides of the longitudinal groove of inner fold of the lid, then the sheet is folded by its longitudinal groove of the inner fold of the back cover, holes are drilled forming a plurality of pairs of holes on both sides of the longitudinal groove of the inner fold of the back cover, then the sheet is folded by the longitudinal groove essentially located in the central part of the spine towards the outside of the binding elements, matching the respective longitudinal grooves and then

SUBSTITUTE SHEET (RULE 26) the pre-drilled sheets are attached for binding, matching their respective drilled holes with those of the sheet and in the next step the binding elements are introduced to join the folded sheet with the sheets, the binding elements are closed, the lid is moved or back cover in the direction to close the document, dragging and moving the spine material and covering the binding elements.

The invention also relates to the use of the cover, for binding sheets using binding elements, such as hoops, discs, rings, wire or others of this type.

The system according to the present invention provides a cover that can be made in a single sheet and that adapts perfectly to the document being bound, providing it with a professional finish. It can easily be attached to binding systems that use binding elements, such as hoops, discs, rings, wire or others of this type. It provides a protection of these binding elements and allows the title of the document content to be placed on the back of the spine, for example, both before the cover manufacturing process and after the binding. In addition, it allows easy opening of 180 ° and even 360 °. Its construction allows to obtain a very useful system and at a reduced cost.

Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature.

Detailed description of the invention

As shown in Figures 1-a, Ib and 2, the cover, according to the present invention for document binding by drilling the sheets and binding elements, comprises cover 2, back cover 3 and spine 4 , which are formed by a sheet 1. Said sheet 1 comprises at least one longitudinal groove 5 essentially located in the central part of the spine 4, a longitudinal outer fold groove 6 of the lid 2 and a longitudinal outer fold groove 6a of the back cover 3, as well as a longitudinal groove of inner fold 7 of the cover 2 and a longitudinal groove of inner fold 7a of the back cover 3, which allow the desired fold of the sheet in an easy, flexible and

SUBSTITUTE SHEET (RULE 26) repetitive

The longitudinal groove of the outer fold 6 and the longitudinal groove of the inner fold 7 of the cover 2 form between them a guide surface 10, same as the longitudinal groove of the outer fold 6a and the longitudinal groove of the inner fold 7a of the back cover 3 form among them a spine guide surface 10a. These spine guides link the cover and back cover with the spine and make hinges of the adjacent panels facilitating their movement when opening or closing the bound document.

Next, a plurality of pairs of holes 8 on both sides of the longitudinal groove of the inner fold 7 of the lid 2 and a plurality of pairs of holes 8a on both sides of the longitudinal groove of the inner fold 7a of the back cover 3, allows the binding with the binding elements 11.

The spine guide surface 10 of the cover 2 is joined to the spine 4 by the longitudinal outer fold groove 6 and contains a plurality of holes drilled longitudinally, and the spine guide surface 10a of the back cover 3 joins the spine 4 by the longitudinal groove of outer fold 6a and contains a plurality of holes drilled longitudinally. During the binding procedure, when placing the sheet 1 with the document to be bound, both the cover 2 and the back cover 3 are folded respectively along the axes of their longitudinal grooves, while the respective holes are essentially adjacent to the binding edge and receive the binding elements, as presented in Figure 1-a. Said longitudinal grooves of inner fold 1 and remain in the inner part of the binding elements, while said longitudinal grooves of fold

SUBSTITUTE SHEET (RULE 26) outside 6 and 6a remain on the outside of the binding elements, as shown in Figure Ib.

In one embodiment of the invention, the cover may have two more pre-marked longitudinal grooves in the spine part 4, such as additional longitudinal grooves 9 and 9a, as shown in Figure Ib, although the invention allows including a variable number of additional slits. The number of additional indentations and the size of the spine will depend essentially on the number of the sheets that make up the document to be bound, especially its thickness, the thickness of the binding elements and the final appearance that it is desired to give it.

According to the invention, each pair of holes 8 of the cover 2 and simultaneously each pair of holes 8a of the back cover 3, receives a binding element, so that each binding element holds the cover in four points, which allows Proper clamping of the parts that form the cover with the bound document, facilitates the movement of the cover and back cover when opening and closing the document and provides great mechanical resistance to binding.

In this way, both the pairs of holes, as well as the respective longitudinal grooves, allow, when opening the lid of the bound document, it can easily slide through the binding elements and make all the surfaces that make up the spine fold down their axes .

The central longitudinal groove 5 makes the spine not completely flat and stays outside the binding elements without hindering the movement of the sheets for reading, since the central longitudinal groove 5 facilitates the opening and binding of the document, to the bend outward from the elements of

SUBSTITUTE SHEET (RULE 26) binding. However, the surfaces that make up the spine cover the binding elements 11, which remain hidden as shown in Figure 1-a or Ib, protecting on the one hand said binding elements and on the other hand providing a free space where the title or other type of marking can be placed according to the existing demand, both before and after the binding procedure.

In addition, the design of the cover according to the invention allows it to be placed together with the document to be bound, so that the cover 2 and the back cover 3 are essentially parallel to the bound sheets. This allows the proper hold of the sheets, giving them a correct consistency. Such a clamp was not possible with other binding systems or with the known binding elements, as shown in Figure 14.

The binding elements preferably comprise rings, discs, rings, wire or other elements of this type and can be made of plastic, metal or other suitable material for this purpose.

The sheet materials that can be used preferably comprise semi-rigid materials, such as plasticized paper, cardboard, polypropylene or other materials of this type, whereby the cover can be manufactured at a low cost and with the material to be Consider appropriate for each situation. These materials facilitate sliding through the binding elements.

In a possible embodiment of the invention, cover 2, back cover 3 and / or spine 4 of the cover can be of different materials, but all joined together forming sheet 1.

The design and the material of the cover according to the invention also allows an easy opening of the bound document with said cover of 180 ° and even 360 °, as demonstrated in the corresponding figures

SUBSTITUTE SHEET (RULE 26) 3a, 3b and 4. These openings are made possible because the spine easily folds through the pre-marked grooves and adjusts to the opening of the document. With the 180 ° opening the spine is folded down by its folding grooves and can be left, for example, in the two different ways shown in Figures 3a and 3b, while with the 360 ° opening the spine bends totally by its central longitudinal groove 5 towards the outside of the binding elements and is between the cover and back cover as shown in figure 4, so that sheets, cover and back cover remain on a single side of the binding elements 11 On the other hand, to close the lid again from the open 360 ° state, it is easily found by the configuration of the spine when it is folded on itself, allowing it to be easily found between the bound sheets.

The cover according to the present invention also adapts to the different thickness of the document to be bound, as shown in the corresponding figures 13a and 13b. The cover of the same size rests on the binding elements, adjusting to the size of the binding elements and the thickness of the sheets to be bound. This possibility is due to the flexibility of the premarked folding grooves, thus allowing easy sliding along the binding elements. Thus, both the cover and the back cover, regardless of the thickness of the document to be bound, remain essentially parallel to the bound sheets, providing their proper support and providing them with adequate consistency. As shown in Figures 5 to 7, the cover binding procedure according to the present invention comprises the steps in which the sheet 1 is folded by its longitudinal inner fold groove 7 of the cover 2 and is they drill the holes with a

SUBSTITUTE SHEET (RULE 26) Conventional drilling system, such as with a standard office drill, forming a plurality of pairs of holes 8 on both sides of the longitudinal groove of the inner fold 7 of the cover 2 (Figure 5). In the same way, the sheet 1 is folded by its longitudinal inner fold groove 7a of the back cover 3 and the holes are drilled, forming a plurality of pairs of holes 8a on both sides of the longitudinal inner fold groove 7a of the back cover 3 (figure 6). Next, the sheet 1 is folded by the longitudinal groove 5 located essentially in the central part of the spine 4, towards the outside of the binding elements, matching the respective longitudinal grooves 1 and the. (figure 7).

Then, according to Figure 8, the previously drilled sheets for binding are coupled, matching their respective drilled holes with those of the sheet and the binding elements are introduced to join the sheet of the folded cover with the sheets. Preferably, the folded sheet is introduced first and then the sheets to be bound to the binding elements. Then, the binding elements are closed in a traditional way, as shown in Figure 9. To complete the process, the back cover is moved in a direction of rotation (or the cover and the sheets in the opposite direction) as as presented in figure 10, dragging (if any) the final rib 12 of the binding element and thus displacing the spine material and essentially covering the binding elements in its entirety and obtaining the final result shown in figure 11 .

Such a design of the spine provides a reinforcement of the binding elements, such as hoops, discs, rings or wires, preventing their deterioration or crushing during use or transfer, protecting users from possible

SUBSTITUTE SHEET (RULE 26) hooks, for example with clothing or other surfaces.

The drilling of the cover can be carried out in the manner described above, but in case of having a suitable machine, the drilling can be done only once and simultaneously with the sheets to be bound. Generally, the type of drilling will depend on both the binding system and the binding elements. The holes in different shapes and steps have been shown in Figure 12 for different binding systems. So that in one embodiment of the process of the invention, all pairs of holes 8, 8a are obtained simultaneously, by folding the sheet 1 by its longitudinal groove of inner fold 7 of the lid 2, folding the sheet 1 by its slot longitudinal longitudinal fold 7a of the back cover 3, folding the sheet 1 by the longitudinal groove 5 located essentially in the central part of the spine 4 towards the outside of the binding elements, matching the respective longitudinal grooves 7, 7a and then drilling the holes thus forming the pairs of holes 8, 8a.

Thus, the binding process according to the invention can easily be incorporated into existing binding systems, both manual and automated, using the elements and manufacturing means already known.

The use of the cover according to the present invention consists in its application to easily bind sheets, documents, manuals, books or others using the binding elements, such as hoops, discs, rings, wire or others of this type, conventionally used in this field.

Next, it should be taken into account that the details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacture of the

SUBSTITUTE SHEET (RULE 26) cover of the invention or in the binding procedure, may be conveniently replaced by others that are technically equivalent and do not depart from the essentiality of the invention or the scope defined by the claims included below.
