Description

DESCRIPTION OF THE PATENT FOR INDUSTRIAL INVENTION:

Entitled: "Procedure, peria transformation of the binding

TEXT OF THE DESCRIPTION

Bookbinding is an artisanal activity that has been transformed into an industrial activity and has as its object the binding of books, registers, albums, etc.

In fact, in the past the work of bookbinding, that is the activity aimed at orderly grouping the various parts of which a book is composed, to provide for keeping it together and for its final presentation, was totally manual.

Since then, enormous progress has been made in the construction of the most complete machinery and with the greatest production capacity, leading to very notable forms of automation.

Bookbinding, today technically understood as an organized activity for the packaging of all the products of the graphic publishing industry, is currently made up of a series of work specializations, both on an artisanal basis and at the level of large% industrial production; specializations that can be divided. -dere in the following main groups:

- staple packaging of brochures and magazines;

- packaging of bulletin-blocks;

- decoration technique.

In the current state of the art, it is known that for the packaging of paperback volumes, after the paper preparation and signature sheets folding steps, if the type of paper requires it, a first pressing with the press is carried out. for signatures to eliminate the air inside the folded sheets.

We then move on to the spreading and collection of the signatures which can be carried out manually or with the special gathering machine.

The registration or control of the collected signatures then takes place before moving on to sewing which can be carried out in various ways.

In the milled paperback the seam is replaced by a cut of the back of the signatures, the loose sheets of which are glued by means of brushes or gluing rollers with glues based on vinyl or. if made by machine, even with thermo-adhesives. plastic models.

Then apply the cover, after gluing the back of the vault, and smooth the back to make it adhere perfectly.

at this point the volume is ready to be trimmed into the letter opener.

It is also known that for the packaging of bound or boxed volumes there is a very wide range of systems, of binding and of the materials used for the lining of the cardboard cover. In fact, bound volumes can be flexible or rigid with normal end sheets or incorporated in the first and last signature or with reinforced end sheets, in canvas; they can have a round or square back, they can be sewn with thread or string, or milled and .glued; the folders can be covered with normal paper, normal plastic paper, special paper for bookbinding, canvas, plastic material, real leather, or by means of combinations of the materials described above.

The ex novo ligation of a normal volume requires the following operations;

i) - For the packaging of the book block:

- splitting of paper with letter opener;

- folding of the sheets into signatures by hand or with folders;

- pressing of the signatures with a press;

- gluing of end sheets manually or by machine;

- expanse of signatures;

- collection of signatures;

- collection control;

- sewing with thread with loom or with stapler;

- pressing with mechanical and / or hydraulic presses or presses;

- gluing of the back manually or with the incolladorsi;

- raising of the back;

- edge trimming with letter opener;

- sinking of the back with a hammer or with the curbstone; - hand or mechanical wrapping; _ - attachment of the capital by hand or with the capitellatrice; - gluing the spine of the book to a paper or gauze support

the block of the ingarzato book is made integral with the cardboard cover by gluing it to the end sheets, leaving the spine flexible;

b) - For the packaging of the cardboard cover:

- cutting the cardboard into mirror quadrants; - cutting the covering material;

I have spines for hard-backed hardback covers; - assembly of the cardboard quadrants and the back on the covering material after pre-gluing it and riveting the protruding edges towards the inside of the folder by hand or with the clincher:

- pressing of the cardboard cover to make the cardboard adhere to the material.

c) - For embedding and finishing the volume:

embedding of the book block in the hardcover a

or with the casing machine;

pressing with single or double presses or presses;

formation of the canal with the bone splint or with the

canaletto press

final-check by hand;

what has been stated is evident the existing diversity - between -

two, described binding systems; the pre-bound volume

feel the following major advantages - compared to the one-in bros -

sura:

extremely easy to open for consultation or reading;

- once opened, it easily maintains said pre-selected position

as it does not have the pages glued on the back of the cover

na:

greater consistency of the hardcover

longer duration in wear.

Obviously the costs for binding volumes are much higher than those for paperback.

The purpose of the present invention is to provide a method for making paperback books which, however, have characteristics similar to those bound in cardboard.

The resulting advantages over traditional paperback binding are as follows:

- flexibility of the back;

The ease of opening the book;

- easy maintenance of the position - chosen book open - greater consistency of the cover;

_ greater resistance to wear over time;

- savings on the quality of the cover cardboard

- possibility of using any existing perfect binder machine without making changes;

- Possibility of creating pockets and / or flaps by eliminating the preliminary cut on the front and the die-cutting of the cover for the execution of the pocket:

- herd of the grain of the cover for the coupling of the two supports;

- procedure that can be carried out with simple and economical machinery! - possibility of coupling very rigid cover and foiling materials;

- possibility of creating new types of cover.

furthermore, said process is considerably advantageous from an economic point of view with respect to the box-binding system.

The above purpose is achieved through the use of a sheet of paper of a size preferably - identical - to the same, so that, with a single process, it is glued on the cover itself by means of a strip of glue-of-variable height -

leaving the back free.

A variant according to the present procedure consists in the use of the same sheet of paper pasted on the entire cover except on the spine.

A further variant, always in accordance with the present procedure, consists in the use of a sheet of paper which folds on itself gives rise to the coupling of its two parts acting as a cover made integral with each other by means of two layers of glue of height variable, leaving however freedom of movement between the back of the external part and the back of the part of the same

The spine of the book is previously glued to the cover using the traditional paperback system,

in order to better clarify the process in question and the aims of the invention, the following description refers to some non-limiting examples illustrated in the attached schematic drawings for demonstration purposes only, in which:

- fig. 1 is the perspective view of a closed book to which the process object of the invention has been applied;

- fig. 2 represents a perspective view of the book in open position of fig. 1;

- fig. 3 is a partial section in elevation shown in Fig. 1;

- Fig. 4 is a perspective view of a closed book in which a variant has been applied according to the process itself;

- fig. 5 represents a perspective view of the book in the open position of fig. 4;

- the. fig, 6 is a partial section in elevation of the book of fig._4

- fig. 7 is a perspective view of a sheet constituting another variant according to the procedure itself;

- fig. 8 is a perspective view of the sheet of figure 1.

7 folded in on itself:

- fig. 9 is a perspective view of the same sheet of which on figs. 7 and 8, further folded:

- fig. 10 represents a perspective view of a book bound by a method according to the invention provided with flaps;

- fig. 11 is a perspective view of a book

according to the invention provided with pockets and flaps: - fig. 12 represents a perspective view of a book bound with a method according to the invention, provided with a plurality of sheets folded like an accordion.

reference to figs. 1, 2, 3, the binding process of book 10, according to the patent, provides for the milled trossura operation, cutting the back of the signatures, or sewing them, whose loose or sewn sheets 11 are fixed on their back 114 with a layer of glue 13 to the back 19 of the sheet 12 by using brushes or gluing rollers; the adhesives can be vinyl-based or also thermoplaetic adhesive adhesives.

Then a sheet of tension paper 12 is inserted, preferably identical to the cover 15 which, by means of a single processing, is made integral with the cover 15 itself with a layer of glue 16 of variable height.

□ If the back 18 of the cover 15 is operated, it is free with respect to the external back of the sheet of paper 12 which, in this case, becomes a risguard.

This procedure, in addition to guaranteeing a structural reinforcement of the book in its most stressed part, achieves its main purpose which is to allow thanks to the inde- pendence of movement of the back 19 of the sheet of paper.12 with respect to the back 18 of the cover 15, its easy opening keeping it unchanged in the various reading or consultation positions chosen.

Figures 4,5,6 show a variant according to the invention in which the use of the same sheet of paper 12 is provided, joined together, by means of a layer of glue 16, with the entire cover 15 of the book 10 except on the back 18 of the same.

This variant presents, in addition to the same advantages already mentioned with the application of the partially glued sheet of paper 12, the fact of considerably increasing the consistency of the total thickness of the cover 15. thus significantly reducing the resulting costs, since card stock is economically much more expensive than paper.

of course, instead of the sheet of paper 12, sheets of. plastic, - magnetic-sheets, -or-sheets of other suitable material. this procedure is applicable to all types of covers, including flexible ones

in figs. 7.8.9 shows a further variant according to the invention in which the use of a sheet of paper 20 is provided which, when folded on itself, gives rise to the coupling of its two parts 28 and 29 acting as a cover, made integral with each other. by means of two layers of glue 16 of variable height.

Thus by operating the back 30 of the external part 29 of the part sheet 20 is free with respect to the back 31 of the underground part 28, this to allow their reciprocal and independent movement and therefore guarantee the same advantages already mentioned above.

In fig. 10 shows a further variant In accordance with the process in question in which the use of a sheet of paper 21 is provided, integrally joined by gluing to the cover 15, provided with flap flaps 22 whose fold line is preferably recessed with respect to the - the final cutting thread, requested to eliminate the double passage that occurs in the current perfect binding systems with flaps in which, as mentioned, two cutting passes are required.

In fig. 11 shows another variant according to the procedure in which the sheet of paper 23 is glued on three sides perimeter to the cover 15 to form one or more counting pockets 24 whose openings 17 can be created indifferently on any side. of the book.

containing pockets 24 can also be advantageously split to contain CDs, road maps, advertising inserts, etc.

The cover 15 can in turn be provided or not with flap flaps 25

This variant has a considerable economic advantage with respect to the production of traditional pockets since the costs of punching and gluing the pocket with a suitable machine are eliminated.

In fig. 12 shows a further variant, again in accordance with the process in question, in which the use of a sheet of paper 26 integrally joined by gluing to the cover 15, provided with foldable sheets with op-

portuna -impagi nation, for example accordion 27.

From what has been described up to now, the advantages deriving from the procedure described are clear. .

The invention is not limited by the examples described and represented but the scope of the process extends to any other analogous or equivalent solution capable of achieving the objects set out above.
