As a whole, the valley is formed in the first portion and the crest is formed in the second portion. It is folded in, is intended to include a bookbinding method.

Hereinafter, a bookbinding apparatus (hereinafter, referred to as “present apparatus”) and a bookbinding method (hereinafter, referred to as “present method”) of the present invention will be described together. In both the present apparatus and the present method, the cover formed by the folded back cover and the signature formed by the laminated paper and crossed over the main surface thereof are formed by the folded back of the cover. An apparatus and method for binding a book in which a valley and a crest formed by folding the signature are attached by bonding. The cover is folded back at the spine, forming a front cover and a back cover. The signature is formed by laminated paper and is folded back across its major surface to form the book content. The cover and signature are the valley of the cover, formed by folding,
The crest of the signature, formed by folding, is attached by gluing, and the book is completed. The present apparatus and the present method are an apparatus and a method for binding such a book.

The apparatus accepts an unfolded cover before the spine portion is folded and an unfolded signature before being folded back across the main surface. The method also includes accepting an unfolded cover before the spine portion is folded and an unfolded signature before being folded across the major surface. The unfolded cover is a back cover that is folded back in a later process to form a cover, and is a flat shape before being folded. Unfolded signatures are folded back to cross the main surface in the later process to form the contents of the book,
This is before folding, formed by laminating a plurality of paper sheets on which different page portions are described on the left and right. The apparatus and method accept these unfolded covers and unfolded signatures. Acceptance may be by any method, for example,
Even if a certain number of unfolded covers and unfolded signatures are received in separate hoppers at a time (each part will be paid out from the hopper according to the progress of bookbinding), It may be acceptable to accept each part according to the situation (so-called manual error). However, in order to perform high-speed and large-volume processing, it is preferable that a large number of unfolded covers and unsigned signatures be received at once by a hopper or the like, and that the hoppers be dispensed by an automated conveyor or the like.

The present apparatus has a glue applying means for applying a glue to the first portion which becomes the valley portion of the unfolded cover and / or the second portion which becomes the ridge portion of the unfolded signature. The method also includes applying a glue to a first portion of the unfolded cover that will be the valley and / or a second portion of the unfolded signature that will be the ridge. The first portion refers to the portion of the unfolded cover that becomes a valley formed by folding the unfolded cover later together with the unfolded signature. The second portion refers to a portion of an unfolded signature that forms a mountain formed by folding the unfolded signature together with the unfolded cover later. The portion to which the glue is applied may be any of the three types of only the first portion, only the second portion, and both the first portion and the second portion. The paste to be applied may be any paste as long as it can be used for bookbinding. For example, a so-called emulsion paste or hot melt paste can be used. The application of the glue can be performed by various known methods, for example, application using a brush, application by spray injection, discharge from a nozzle, and the like.

The present apparatus has a superposing means for superposing an unfolded cover and an unfolded signature such that the first portion and the second portion overlap at a predetermined position. The method also includes superposing the unfolded cover and the unfolded signature such that the first portion and the second portion overlap at a predetermined position. The unfolded cover and unsigned signature are well overlapped by their first and second parts so as to provide the proper positional relationship between the cover and the signature in the final book. Are superimposed. For this purpose, the unfolded cover and the unfolded signature may be overlapped in a state where the reference positions are overlapped.

The present apparatus has a pressing means for pressing a portion of the portion where the unfolded cover and the unfolded signature are in contact with the glue so that the unfolded cover and the unfolded signature are in close contact with each other. In addition, the method includes pressing a portion of the portion where the unfolded cover and the unfolded signature are in contact with the paste so that the unfolded cover and the unfolded signature are in close contact with each other. By pressing the portion to which the glue is applied, the unfolded cover and the unfolded signature in that portion can be brought into close contact with each other, and the two can be firmly and reliably bonded. Any method of compression may be used. For example, a method of pressing an unfolded cover and an unfolded signature between two flat plate members and pressing, or a method of pressing an unfolded cover and an unfolded cover. It can be performed by a method in which a signature and a signature are sandwiched between two rollers and passed under pressure. In addition,
The compression does not necessarily have to press the entire part to which the glue is applied, and even if it presses a part of the part, the unfolded cover and the unfolded signature can be firmly and securely bonded to each other. Anything is fine. Further, when pressing the portion where the glue is applied, the portion where the glue is not applied and where the unfolded cover and the unfolded signature are in contact may be pressed simultaneously. Compression conditions such as pressure and time for compression may be determined as appropriate according to the type of unfolded cover, unfolded signature and glue, dimensions of unfolded cover and unfolded signature, and the like.

The present apparatus has folding means for integrally folding the unfolded front cover and the unfolded signature so that a valley is formed in the first portion and a ridge is formed in the second portion. . The method also includes integrally folding the unfolded cover and unfolded signature together such that a valley is formed in the first portion and a ridge is formed in the second portion. A glue is interposed between the first part and the second part of the compressed unfolded cover and unfolded signature. In this state, the unfolded cover and the unfolded signature are integrated, and the unfolded cover and the unfolded signature are folded back. The folding is performed such that a valley is formed in the first portion and a ridge is formed in the second portion. As a result, the signature is sandwiched between the covers, and the book is completed.
The folding may be performed by any method, and may be performed not only by a machine but also manually.

[0015] This apparatus is designed so that the unfolded cover and the unfolded signature can be easily folded back by the folding means so that the unfolded cover and the unfolded signature reach the folding means. You may make it further have a hammering means which performs a hammering along the folded part of a cover and / or an unfolded signature. In addition, the method further includes the steps of unfolding the unfolded cover and / or the unfolded signature so that the unfolded cover and the unfolded signature can be easily folded back together.
Alternatively, it may further include performing a hammering along the folded portion of the unfolded signature. By doing so, the first portion and the second portion can be easily and surely folded by pressing the main surface of the unfolded cover sheet and the unfolded signature in a predetermined direction, which is preferable.
The habit may be applied by any method. For example, by rotating the roller while pressing the side portion (circumferential portion) of the disk-shaped roller against the portion where the habit is to be applied,
Alternatively, it can be performed by pressing a pressing die.

Thereafter, if necessary, a part of the periphery of the book may be cut (so-called top-bottom cutting) or a cover may be attached.

[0017] The apparatus may further comprise a transport means for continuously transporting the unfolded cover and the unfolded signature. Further, the method may be performed while the unfolded cover and the unfolded signature are continuously conveyed. The unfolded cover and unfolded signature are received, and the unfolded cover and unfolded signature are continuously conveyed through the positions where the respective processes are performed until the book is completed by folding back both. . If the processing and the transport need to be synchronized, the two may be synchronized by appropriately providing a detecting means such as a position. The conveyance may be performed by any method, and examples thereof include a belt conveyor, a roller conveyor, a bucket conveyor, and a moving hanger.

When the unfolded cover and the unfolded signature are continuously transported, the unfolded cover is transported by the first transport unit until the received unfolded cover and unfolded signature are overlapped. The unfolded signature may be conveyed by the second conveying means. In this way, the unfolded cover and the unfolded signature are transported by independent and separate transport means, so that there is a large degree of freedom in adjusting the positions of the unfolded cover and the unfolded signature. Can be superposed well.

When the unfolded cover is transported by the first transporting means and the unfolded signature is transported by the second transporting means, the unfolded cover and the unfolded signature are separated by the following configuration. Accurate, quick, and smooth overlapping. That is, the overlaying means, the unfolded cover sheet being transported by the first transport means, and the unfolded signature transported by the second transport means, detecting means for detecting the respective positions, and A first method for reducing the relative speed between the unfolded cover and the unfolded signature when the unfolded cover and the unfolded signature overlap at a predetermined position and the unfolded cover and the unfolded signature overlap. Calculating the transport speed of the transport means and / or the second transport means from the signal emitted by the detecting means, and instructing the first transport means and / or the second transport means to transport at the transport speed; Command means. In addition, the unfolded cover and the unfolded signature are superimposed on the unfolded cover being transported by the first transport unit and the unfolded signature being transported by the second transport unit. Detecting the position, and the relative speed between the unfolded cover and the unfolded signature when the unfolded cover and the unfolded signature overlap at a predetermined position and the unfolded cover and the unfolded signature overlap; The transport speed of the first transport unit and / or the second transport unit that reduces the distance is calculated from the detected position, and transported to the first transport unit and / or the second transport unit by the transport speed. And a command to do so.

First, the positions of both the unfolded front cover and the unfolded signature are detected. Secondly, from both the position of the unfolded cover and the unfolded signature, the transport speed of the first transporting means transporting the unfolded cover and / or the second transporting of the unfolded signature. Calculate how to set the transfer speed of the transfer means. The calculation is performed so as to reduce the relative speed between the unfolded cover and the unsigned signature when the unfolded cover and the unfolded signature overlap at a predetermined position and the unfolded cover and the unfolded signature overlap. Done. The term "reduce the relative speed" as used herein means that the position of the unfolded cover and the unfolded signature is adjusted, and the unfolded cover and unfolded signature are greater than the maximum relative speed of both. Means that the relative speed is small when they overlap. By doing so, the two parts overlap at a predetermined position in a state where the relative speed of the two parts is small, so that the two parts can be accurately and smoothly overlapped, and at the same time, it is possible to prevent the sticking out of the applied paste by rubbing the applied paste. Can be. The relative speed is preferably as small as possible, and most preferably 0. In order to superimpose the two at a predetermined position, while adjusting the positions of the two according to the difference in the conveying speed of the two, when the two finally overlap, the conveying speed of the two is reduced (most preferably to 0) (necessary until the two overlap). The difference in the transport distance should be the difference between those obtained by integrating the two transport speeds with respect to time.) Third, the first and / or second conveying units are commanded to convey at the calculated conveying speed. The calculation and command of the transport speed may be performed only for the first transport unit (the transport speed of the second transport unit is constant) or may be performed only for the second transport unit (for the first transport unit). The transfer speed is constant), and even when the transfer is performed for both the first transfer unit and the second transfer unit (both the transfer speed of the first transfer unit and the transfer speed of the second transfer unit change). Do) good.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the drawings based on embodiments, but the present invention is not limited thereto.

FIG. 1 is an explanatory view of a bookbinding apparatus according to one embodiment of the present invention. Referring to FIG. 1, a plurality of unfolded covers 1 are received in a hopper 3. A dispensing roller 5 for dispensing the unfolded cover 1 partly from the hopper 3 is arranged. A belt conveyor 7 as a first transport unit for transporting the unfolded cover 1 paid out by the payout roller 5 is provided. In the case of this embodiment, the belt conveyor 7 not only transports the unfolded cover 1 but also
It is also configured to convey a product in which the signature 11 and the unfolded signature 11 are overlapped. A cover detection photoelectric tube 9 for detecting the passage of the unfolded cover 1 is mounted on the belt conveyor 7. A glue extruder 19 serving as a glue applying means for applying a glue to a predetermined position (first portion) of the unfolded cover 1 that has passed through the cover detection photoelectric tube 9 is arranged. Glue extruder 1
9 applies the glue 21 in a direction parallel to the transport direction of the unfolded cover 1. On the other hand, the unfolded signatures 11 are partially received by hand. As with the unfolded cover 1, a certain number of unfolded signatures 11 may be received by a hopper or the like, and the unfolded signature 11 may be mechanically dispensed from there. A signature detection photoelectric tube 13 for detecting the passage of the unsigned signature 11 is mounted on the transport path of the unsigned signature 11. A roller conveyor 15 as a second transporting means for transporting the unfolded signature 11 is provided. The roller conveyor 15 is formed by a pair (two) of rollers, and is driven by a servomotor 17 whose rotation speed can be freely changed. A compression roller 23 is arranged to pass the unfolded signature 11 conveyed by the roller conveyor 15 and the unfolded cover 1 conveyed by the belt conveyor 7 in a superimposed state. The compression roller 23 is composed of a pair (two) of rollers. The unfolded signature 11 and the unfolded cover 1 pass between these rollers in a state where they are overlapped with each other to be pressed and come into close contact.
Thereafter, a customizing roller 25 is arranged at a position where the unfolded cover 1 and the unfolded signature 11 pass. A continuous projection is formed on the side surface of the customizing roller 25, and the customizing can be performed by rotating the projection while pressing the projection against the unfolded signature 11. Finally, the unfolded signature 11 and the unfolded cover 1 are folded by pressing the vicinity of the unfolded portion. The folding is performed by pressing machine 27 which presses unfolded signature 11 and unfolded cover 1 from above.
And a pair (two) of rollers 29 that support the unfolded signature 11 and the unfolded cover 1 so as to be able to be folded back.

Next, the procedure for binding using the apparatus shown in FIG. 1 will be described. Here, the terms "upstream" and "downstream" mean the upstream and downstream when the unfolded cover sheet 1 (from the middle is integrated with the unfolded signature) while being transported while being processed. The press 27
Is located at the most downstream side. First, the hopper 3 receives a predetermined number of unfolded covers 1. The main surface of the unfolded cover sheet 1 located at the most downstream side in the hopper 3 is in contact with the payout roller 5, and is discharged toward the belt conveyor 7 by rotating the payout roller 5.

On the other hand, the unsigned signature 11 is received by hand, and the edge of the unsigned signature 11 is
Is reached, the signature detection phototube 13 detects the reception of the unsigned signature 11. When receiving the detection signal of the signature detection photoelectric tube 13, the payout roller 5 starts rotating, and the unfolded cover 1
A part is paid out to the belt conveyor 7. When the edge of the unfolded cover 1 being conveyed by the belt conveyor 7 reaches the cover detection phototube 9, the cover detection phototube 9 detects the conveyance position of the unfolded cover 1. Based on the signal emitted by the signature detecting photoelectric tube 13 and the signal emitted by the cover detecting photoelectric tube 9, the respective positions of the unsigned signature 11 and the unfolded cover 1 are detected (detection means).

The unfolded cover 1 whose position has been detected by the cover detection photoelectric tube 9 is then conveyed to a glue extruder 19 and coated with glue. The glue extruder 19 senses that the unfolded cover 1 has been conveyed, starts extruding the glue, and applies a predetermined amount of glue on the surface of the unfolded cover 1. In the present embodiment, the glue 21 is applied to a portion (first portion) that becomes a valley portion of the folded back cover when the book is completed. Glue 2
1 is applied as the unfolded cover sheet 1 is transported, so that it is applied in a streak shape parallel to the transport direction as shown in the figure.

Based on the detected positions, the unfolded signature 11 and the unfolded cover 1 are positioned at a predetermined position (that is, when the book is completed, become a valley of the cover formed by folding back) at the pressing roller 23. (The position where the part (the first part) and the ridge part (the second part) of the signature formed by folding back overlap well), and unfolded signature 11 and unfolded when overlapping. The rotation speed (change) of the roller conveyor 15 is calculated so that the relative speed with respect to the cover 1 (the relative speed of the two in the transport direction) becomes zero, and the servo motor 17 is commanded (calculation command means) (belt conveyor). 7 is constant.) This rotation speed (change)
Is calculated as follows. That is, first, a difference in transport distance between the unfolded signature 11 and the unfolded cover 1 at the predetermined position is calculated for the compression roller 23 (for example, the unfolded signature 11 is attached to the unfolded cover 1). If the vehicle is late, calculate the distance of the delay.) Second, the speed of the roller conveyor 15 (the speed of the servomotor 17) is changed with respect to the speed of conveyance by the belt conveyor 7 so as to give the difference in the conveyance distance to both. What is necessary is just to integrate the difference between the transport speed of the belt conveyor 7 and the transport speed of the roller conveyor 15 with respect to time so as to be the transport distance difference. Finally, compression roller 2
3 so that the unfolded signature 11 and the unfolded cover 1 overlap smoothly, so that when the two overlap, the relative speed in the transport direction becomes zero (that is, the unfolded signature 11 is transported). So that the speed and the transport speed of the unfolded cover 1 match)
I do.

After that, the unfolded signature 11 and the unfolded cover 1 are overlapped at a predetermined position, and both are integrated into the compression roller 23. The compression roller 23 presses the unfolded signature 11 and the unfolded cover 1 so as to be in close contact with each other. This also compresses the portion to which the glue 21 is applied, and ensures the adhesion by the glue 21.

The unfolded signature 11 and the unfolded cover 1 that have passed through the compression roller 23 and are brought into close contact with each other
(Having means). Hammering roller 2
5 has a continuous stripe-shaped projection on its side surface, and rotates while this projection is pressed against the unfolded signature 11. As a result, a groove-shaped habit 31 is formed on the upper surface of the unfolded signature 11 in a direction parallel to the transport direction. The habit 31 is formed along a portion where the unfolded signature 11 and the unfolded cover 1 are folded back later, thereby facilitating the folding and determining the folding position.

Finally, the unfolded signature 11 and the unfolded cover 1 to which the habit 31 has been attached by the hammering roller 25 are arranged on the roller 29. The roller 29 is composed of two rollers that can rotate freely, and the unfolded signature 11 and the unfolded signature 11 are arranged such that the habit 31 attached to the unfolded signature 11 is located almost in the center of the two rollers. Cover 1
Are arranged on the roller 29. In this state, the upper surface of the unfolded signature 11 and the unfolded cover sheet 1 are pressed down by the press machine 27. A pressing plate 27a is attached to the press machine 27 along a direction in which the unfolded signature 11 and the unfolded cover 1 are to be folded, and this and the formed habit 31 are combined in a desired direction. The unfolded signature 11 and the unfolded cover 1 can be folded back. The press machine 27 may be any machine as long as the press plate 27a can be moved up and down as desired, and examples thereof include a machine driven by a hydraulic pressure, a pneumatic pressure, a magnetic force, and an electric motor.

The book bound as described above is completed by cutting a part of the periphery of the book (so-called top and bottom cutting) or attaching a cover as necessary.

FIG. 2 is an explanatory view of a bookbinding apparatus according to another embodiment of the present invention. Referring to FIG. 2, a plurality of unfolded covers 1
Is received by the hopper 3. A dispensing roller 5 for dispensing the unfolded cover 1 partly from the hopper 3 is arranged. The payout roller 5 rotates counterclockwise in the figure, and pays out the unfolded cover 1 part by part in the right direction in the figure by the outer periphery positioned below. A belt conveyor 7 as a first transport unit for transporting the unfolded cover 1 paid out by the payout roller 5 is provided. A first cover detection photoelectric tube 51 for detecting the passage of the unfolded cover 1 is mounted on the belt conveyor 7. The unfolded cover 1 transported by the belt conveyor 7 is a roller 53
a, 53b, and 53c, and is supplied to the drum 55. The drum 55 has a large number of small holes (not shown) on the side surface (the portion where the main surface of the unfolded cover 1 contacts), and air is sucked from the inside of the drum 55 to suck air from the small holes. Thereby, the unfolded cover 1 is attracted to the side surface. The drum 55 rotates counterclockwise in the figure,
Thereby, the unfolded cover 1 and the like are conveyed. A second cover detection photoelectric tube 71 is disposed near the downstream side of the drum 55 where the unfolded cover 1 is supplied. On the side surface of the drum 55, a glue extruder 19 which is a glue applying means for applying glue to a predetermined position (first portion) of the unfolded cover 1 is arranged. The glue extruder 19 applies the glue 21 in a direction parallel to the transport direction of the unfolded cover 1. On the other hand, the unfolded signature 11 is paid out partly by the rollers 57a, 57b, 57c. The unfolded signature 11 paid out by the rollers 57a, 57b, 57c is first conveyed by the constant speed conveyor 59, and then conveyed by the variable speed conveyor 63 (second conveying means). A signature detecting photoelectric tube 13 is attached near the entrance of the variable speed conveyor 63 (second conveying means). Variable speed conveyor 63 (second conveying means)
Is driven by a servomotor (not shown) whose rotation speed can be freely changed. A compression roller 23 is arranged to pass the unfolded signature 11 conveyed by the variable-speed conveyor 63 (second conveyance means) and the unfolded cover 1 conveyed by the drum 55 while being pressed in a superimposed state. I have. In the case of the present embodiment, the pressing roller 23 is composed of one roller,
When the unfolded signature 11 and the unfolded cover 1 pass between the drum 3 and the drum 55 in a superposed state, they are pressed and come into close contact. Thereafter, a customizing roller 25 is arranged at a position where the unfolded cover 1 and the unfolded signature 11 pass. A continuous projection is formed on the side surface of the customizing roller 25, and the customizing can be performed by rotating the projection while pressing the projection against the unfolded signature 11. The unfolded cover sheet 1 and the unfolded signature 11 that have been hammered are conveyed to the press machine 27 by the conveyor 65. Below the press 27, a pair of rollers 29 (one of two rollers is hidden and cannot be seen) that supports the unfolded signature 11 and the unfolded cover 1 in a foldable manner are arranged.

Next, a procedure for binding using the apparatus shown in FIG. 2 will be described. First, the payout roller 5 is rotated in the counterclockwise direction in the figure to partially pay out the unfolded cover 1 from the hopper 3. The unfolded cover 1 is stacked in the hopper 3, and the height of the unfolded cover 1 is adjusted so that the uppermost one always contacts the payout roller 5. The unfolded cover 1 paid out from the hopper 3 is arranged on the upper surface of the belt conveyor 7 as the first conveying means, and is conveyed rightward in the figure by the movement of the belt conveyor 7. When the edge of the unfolded cover 1 reaches below the position of the first cover detection photoelectric tube 51, the fact is notified to the first cover detection photoelectric tube 5.
1 detects and emits a signal. This signal causes the rollers 57a, 57b, 57c to start rotating, and the unsigned signature 1
1 is paid out to the constant speed conveyor 59. The unfolded cover sheet 1 conveyed by the belt conveyor 7 is then conveyed to the side surface of the drum 55 by rollers 53a, 53b, 53c. The unfolded cover sheet 1 sucked and fixed to the side surface of the drum 55 is conveyed by the movement of the drum 55 rotating at a constant angular velocity in a counterclockwise direction in the drawing. When the edge of the unfolded cover 1 reaches the position of the second cover detection phototube 71, the second cover detection phototube 71 detects this and emits a signal. Thus, the position of the unfolded cover 1 on the side surface of the drum 55 can be recognized. On the other hand, the unfolded signature 1 conveyed leftward in the figure by the constant-speed conveyor 59
1 is a variable speed conveyor 63 (second conveying means)
Move to. Variable speed conveyor 63 (second conveying means)
Unsigned signature 11 conveyed by the signature detection photoelectric tube 13
Is reached, the signature detection phototube 13 detects this and emits a signal. Thus, the position of the unfolded signature 11 can be recognized.

From the signal emitted by the second cover detection photoelectric tube 71 and the signal emitted by the signature detection photoelectric tube 13, the position of the unfolded cover 1 and the position of the unfolded signature 11 are detected, respectively ( Detection means). From these detected positions, just before entering the compression roller 23, the unfolded signature 11
And the unfolded cover 1 at a predetermined position (that is, when the book is completed, a portion (first portion) that becomes a valley portion of the cover formed by folding, and a crest portion of the signature formed by folding. (The position where the second part and the second part overlap well), and the unfolded signature 11 when overlapping.
The transport speed (change) of the variable-speed conveyor 63 (second transport means) is calculated such that the relative speed between the unfolded cover 1 and the unfolded cover 1 (the relative speed of the two in the transport direction) becomes zero. 63 (second conveying means) for driving a servo motor (not shown) (calculation command means) (unfolded cover 1
Is constant, and therefore the conveying speed of the unfolded cover 1 is constant. ). The transfer speed (change) of the variable speed conveyor 63 (second transfer means)
Is calculated as follows. That is, first, a difference in transport distance between the unfolded signature 11 and the unfolded cover 1 at the predetermined position is calculated for the compression roller 23 (for example, the unfolded signature 11 is attached to the unfolded cover 1). If the vehicle is traveling, calculate the traveling distance.) Second, the drum 55 is moved so that the difference in the transport distance is given to both.
The transport speed (the speed of the servo motor) of the variable speed conveyor 63 (second transport means) is changed with respect to the transport speed by the above. Conveyance speed by drum 55 and variable speed conveyor 63
The difference between the transfer speed of the (second transfer means) and the transfer speed may be obtained by integrating the difference with respect to time. Finally, the unfolded signature 11 and the unfolded cover 1 are smoothly overlapped on the pressing roller 23 so that the relative speed in the transport direction of the two when they overlap is 0 (that is, the unfolded signature 11 and the unfolded cover 1 are not overlapped). The transport speed of the signature 11 and the transport speed of the unfolded cover 1 are made to match.

The unfolded cover sheet 1, which is adsorbed and fixed on the side surface of the drum 55, is coated with a glue (not shown) when passing through the position of the glue extruder 19. Glue extruder 1
9 detects that the unfolded cover 1 has been conveyed, starts extruding the glue, and applies a predetermined amount of glue on the surface of the unfolded cover 1. The glue is applied to the valley portion (first portion) of the folded back cover when the book is completed.
