Description

The invention relates to a method according to the preamble of claim 1 for attaching portions of a Hinterklebematerials to the back of a book block. The book block is transported in a book production line in a conveying direction and provided with the back of the book block with an adhesive. Successively, the portions of the backing material are attached by means of at least one conveying means to the back of the book block provided with the adhesive.

The invention further relates to a device according to the preamble of claim 7 for attaching portions of a Hinterklebematerials to the back of the book block, with a conveyor for taking place in a conveying direction transport of the book block through a book production line, a Beleimeinrichtung for applying the adhesive to the back of the book block at least one back-adhesive station having at least one feed device for the back-adhesive material and at least one cutting device for cutting the sections of the back-adhesive material according to a thickness of the back of the respective book block and at least one for forming the portions of the back-adhesive material on the back of the book block provided with adhesive.

The invention further relates to a book production line according to claim 16.

An essential step in the production of books from book blocks is the so-called back-gluing, in which at the back of the book block a mostly strip-shaped reinforcing material of molton, gauze or tear-resistant paper (kraft or crepe paper) is attached to a solidification of the back and thus a To ensure dimensional stability of the later book over its lifetime. An additional reinforcement of the back can be achieved by previously applying gauze, which in a back of the two long sides projecting area together with the there also attached, so-called Attachment sheet performs a hinge function between the spine and the cover. When producing books with a hard cover, a so-called capital ribbon, ie a colored ribbon, is attached to the top and bottom edge of the book block, which decoratively covers the transition from the book block to the cover.

From the DE102013004497 A1 US-A-5 837 931 discloses a method and corresponding apparatus for machine pasting and capitalizing successive book blocks of different back lengths. In this method, successively two portions of a Hinterklebematerials are attached overlapping each other on the back of a book block, the back glued first and the two sections are successively mounted in separate Hinterklebestationen to the back of the book block and finally pressed. In this case, first a first application of adhesive to the part of the back, to which the first portion of the backing material is to be attached. After attaching this first portion to the glued portion of the spine, the remainder of the spine and an overlap region of the backsheet portion of the backsize material are provided with adhesive before the second portion of the backsize material adapts to the spine of the book block and overlap area the first section of the backing material is attached. By this staggered application of the adhesive and the immediate subsequent covering the area provided with adhesive with the corresponding portion of the backing material, contamination of the device can be avoided and thus a largely trouble-free operation of the device can be ensured. In addition, a capital band can be glued to the web of the backing material before the respective sections are separated from this web and attached to the adhesive back of the book block. With regard to the formation of a feed device of the backing material to the two Hinterklebestationen and in particular for the formation of conveying means for attaching the portions of the backing material to the back of the book block is silent DE102013004497 A1 ,

In the EP2269836 A2 For example, there is described a method and apparatus for machine backing the book block back in a book production line equipped with a single backing station. At least two portions of backsheets, namely a portion of the backsheet material covering the entire back of the book block and a latter gauze overlaying the longitudinal sides, are joined together to form a common backsize complex which is attached and pressed as a whole onto the glued back of the book block. The apparatus has at least two feeders for providing different backing materials to a conveyor provided with suction elements, wherein the suction elements are moved between the respective transfer points of the feeders to the conveyor and the back of the book block.

For rapid adaptation of the back-adhesive complex to different spine lengths successively behind the book block to be backed, these feeders can be moved against each other so that overlap the portions of the backing material in Hinterklebekomplex such that the resulting Hinterklebekomplex corresponds to the back length of the respective book block. The disadvantage of this is the unfavorable accessibility to the points of Hinterklebestation where the mutual displacement of the feeders should be made. In addition, the storage devices for the different Hinterklebematerialien must be mounted in mutually displaceable positions, which makes an ergonomic loading of the same impossible. Furthermore, the access to the respective gluing devices or their glue application nozzles is very limited by the space available and the disposal of the Seitenbeschnittes the Hinterklebematerials difficult. Another disadvantage is the relatively large number of splices where the individual backing materials have to be bonded to the backsize complex. At each point of adhesion, and particularly when the gauze strip is adhered, there is the possibility of fouling of the device, which can lead to a disruption of the operation of the book production line.

The EP1894739B1 also discloses a device for pasting and capitalizing the backs of book blocks in a book production line. The Hinterklebematerial is transported with a single feeder to the book production line, cut there, ie tailored according to the thickness of the spine of the respective book block, and attached by means of a suction element of a conveyor to the back of each book block. For this purpose, the suction element is first pivoted into a receiving position, in which it sucks in a previously cut-to-length section of the backing material and transports this section by a pivoting movement in a dispensing position to the back of the book block.

Against the background of this known technique, the object of the invention is to provide a flexible method which satisfies the diverse requirements of the successive manufacture of books with different format and / or content and a corresponding device for pasting over the entire format range of a book production line. The device should, with good accessibility and ease of use have a compact and inexpensive construction, while the process should ensure trouble-free operation without the need for manual intervention in the format change.

The object is achieved by a method according to claim 1 and by a device according to claim 7. Furthermore, a book production line according to claim 16 contributes to the solution of the problem. Advantageous embodiments are objects of the respective subclaims.

In the generic application of sections of a backing material to the back of a book block latter is transported in a book production line in a conveying direction and provided his back with an adhesive. Thereafter, the portions of the backing material are successively attached by means of at least one conveying means to the provided with the adhesive back of the book block.

According to the invention, the back of the book block is first provided with the adhesive in a single application process over its entire back length. Thereafter, a first portion or a first portion and at least one further portion of the backing material from a first conveyor and then at least a second portion or a second portion and at least one further portion of the backing material from a second conveyor overlap each other with the backing provided with the adhesive attached to the book block.

Because of this continuous glue application over the entire back length, a second gluing process and a complete gluing device can be saved compared to the prior art, and thus a more efficient process sequence and a compact, cost-effective design can be realized. The overlapping attachment of the portions of the backing material allows the coverage of a larger format area and thus a more flexible process than with abutting sections. By using two separate conveying means for attaching the sections can be advantageously ensured good accessibility to the feeders.

According to an advantageous embodiment of the method, the sections of the back-adhesive material with the conveying means are positioned on the back of the book block such that the at least two overlapping sections completely cover the back of the book block.

According to a further embodiment of the method, a first portion of the backing material is applied by the first conveying means and a second portion of the backing material is applied by the second conveying means to the back of the book block provided with the adhesive. In addition, at least one further portion of the backing material from the first conveyor together with the first portion and overlapping the first portion and / or another portion of the backing material from the second conveyor together with the second portion and overlapping to the second portion between the first and the second portion attached to the back of the book block. In this case, each section of the back-adhesive material to be subsequently attached to the back of the book block is overlapped with a section already attached to the back of the book block. The sections attached to the back of the book block completely cover this over its back length.

Compared to the use of only two sections of the back-adhesive material, the size range to be covered can be significantly increased by attaching at least one further section of the back-adhesive material. In addition, this further section can advantageously be attached selectively from the first and / or from the second conveying means. Finally, depending on the configuration of the back-adhesive stations and the conveying means, it is also possible to provide a further section or several further sections per conveying means.

According to a further embodiment of the method, the conveying means each have at least one suction element with a first segment and at least one second segment, with the first segment of the first conveying means of the first portion of the Hinterklebematerials and with the first segment of the second conveying means of the second portion of Hinterklebematerials are attached to the back of the book block, while with the respective at least one, second segment of the suction elements no further portion of the backing material is attached to the back of the book block. In this case, the at least one, second segment is or is offset from the first segment in each case such that a contact surface of the first segment contacts the back of the book block, while a contact surface of the second segment is spaced from the back of the book block. Here, "touching" means that the respective contact surface contacts the back of the book block with the portion of the backing material held by it, "spaced" meaning that the respective contact surface does not come into contact with the adhesive applied to the back of the book block.

Due to the spaced positioning of the contact surface of the second segment of the back of the book block, the area of the back of the book block, the Although glued but not covered with a portion of the backing material, yet not be contaminated with adhesive, whereby a trouble-free operation of the device is guaranteed.

According to a further embodiment of the method, the back-adhesive material for the first portion and the back-adhesive material for the at least one further portion overlap each other to the first conveying means and / or the Hinterklebematerial for the second portion and the Hinterklebematerial for the at least one further portion overlapping each other to the second conveyor fed.

With this method, the sections of the backing material can be easily overlapped onto the spine of the book block.

According to a further embodiment of the method, portions of a back-adhesive material are also attached to the spines of a further book block during or after the attachment of portions of a backsize material to the spine of a first book block in the book production line, the spine of the further book block being opposite the spine of the first book block has different back length and wherein the funding in or against the conveying direction are shifted from each other in such a way that after completion of the steps gluing the full back and attaching a first portion or a first portion and at least one further portion and then attaching at least a second portion or a second portion and at least one further portion of the backing material, the first portion of the backing material and the second portion of the backing material or the first Absc Hnitt and at least another portion of the backing material and the second portion and at least another portion of the backing material each overlap each other overlapping the back of the other book block completely.

In this way, advantageously book blocks with different formats can be produced without manual intervention.

Since the device has only a single gluing device for applying the adhesive to the entire back of the book block, a complete gluing device can be saved compared to the prior art and thus a compact and cost-effective design can be realized. Due to the arrangement of at least two separate conveying means, the portions of the backing material can be overlapped on the spine of the book block, whereby advantageously a larger format range of book blocks can be processed with this device. In addition, by using at least two separate Conveyors improved accessibility to the feeders are guaranteed.

According to one embodiment of the device, the conveying means each have a suction element with a first and at least one second segment for receiving, temporarily holding and dispensing each of a portion of the backing material. In this case, the holding of the respective one section takes place during its transport from the rear-gluing station to the back of the book block.

With such, equipped with at least two segments suction elements, the sections of the backing material can be individually attached to the back of the book block, so that one or more sections can be processed with each Hinterklebestation optionally.

According to a further embodiment of the device, the first segment has a first contact surface to the back of the book block and the at least one, second segment a second contact surface to the back of the book block, wherein the at least one, second segment relative to the first segment is made displaceable such that the contact surface of the first segment contacts the back of the book block, while a contact surface of the second segment is spaced from the back of the book block.

However, due to the spaced positioning of the contact surface of the second segment from the spine of the book block, the area of the spine of the book block, which is glued but not covered with a portion of the backing material, can not be soiled with adhesive, thereby ensuring trouble-free operation of the device.

According to a further embodiment of the device, an actuator for displacing the at least one, second segment relative to the first segment is arranged on the suction element.

The actuators are a link of the machine control device which controls the tandem pasting station depending on the format of the book block being processed. At least by means of the actuators, the machine control system controls the feeding devices in use, the position of the displaceable segments and also active bore systems for the application of air / vacuum. The Hinterklebestation is therefore fully automated after such training. It can thus be manufactured without a plant operator having to intervene manually.

According to a further embodiment of the device, equipped with the above-described conveying means, the suction element is arranged interchangeable with the respective conveying means against a different suction element, which differs from the suction element.

In this way, the suction element can be advantageously adapted to a different width of the web of Hinterklebematerials.

According to a further embodiment of the device with the above-described conveying means, at least one first and / or second segment is arranged exchangeably on the respective suction element against a different segment from the first and / or second segment.

Analogously to the previously described advantage, the first and / or the at least one second segment can thus be advantageously adapted to a different width of the web of the back-adhesive material.

According to a further embodiment of the device, at least two feeders for the back-adhesive material are arranged upstream of the first conveyor and / or upstream of the second conveyor and offset relative to one another in the conveying direction such that the back-adhesive material for the first section and the back-adhesive material for the at least one further section overlap one another is fed to the first funding and / or the backing material for the second section and the back-adhesive material for the at least one further section overlapping each other to the second conveyor can be supplied.

In the gluing device 80, the upwardly facing spine 2 of the book block 1 with an applicator roll 81 which can be adapted to the back shape is applied over its entire spine length 9 (FIG. Fig. 6 ) provided with the adhesive 8. Generally afterwards in the upstream (right) Hinterklebestation 16 by means of the conveyor 60, a first portion 3 or a first portion 3 and at least one further portion 4 of the Hinterklebematerials 23, 33 and then in the downstream (left) Hinterklebestation 17 by means of the conveyor 64 at least a second portion 5 or a second section 5 and at least one further section 6 of the backing material 43, 38 overlapping each other on the provided with the adhesive 8 back 2 of the book block 1, this completely covering. In this case, a capital band 26, 46 can additionally be attached to the back-adhesive material 23, 43 for the first and / or the second section 3, 5. Accordingly, either the back-bonding material 23 or a back-adhesive material web 24 formed from the back-adhesive material 23 and the capital bath 26 is available for cutting the first section 3 to length in the right-hand rear-adhesive station 16. Accordingly, for tailoring the second portion 5 in the left back adhesive station 17, either the backsize material 43 or a backsize material web 44 formed from the backsize material 43 and the headband 46 is provided.

Depending on the format of the book block 1 to be processed in addition to the first and second sections 3, 5, at least one further section 4 of the back-adhesive material 33 is transferred from the first conveyor 60 together with the first section 3 and overlapping the first section 3 to the back 2 the glued book block 1 attached. After the subsequent overlapping attachment of the second section 5, the at least one further section 4 is attached between the first and the second section 3, 5 to the glued spine 2 of the book block 1 so that it has both the first and the second section 3, 5 overlaps.

Similarly, depending on the format of the book block 1 to be processed, in addition to the first and second sections 3, 5 and either additionally or alternatively to the at least one further section 4 of the backsheet material 33, the at least one further section 6 of the backsheet material 38 is co-located with the second conveyor 64 the second portion 5 and overlapping the second portion 5 attached to the back 2 of the glued book block 1. The at least one more Section 6 is then attached to the glued spine 2 of the book block 1 between the first and second sections 3, 5 so as to overlap both the first and second sections 3, 5. If, in addition to this at least one further section 6 of the back-adhesive material 38, at least one further section 4 of the back-adhesive material 33 is also applied together with the first section 3, the two further sections 4, 6 attached to the back of the bookbucket overlap one another.

Basically, each subsequent to the back 2 of the book block 1 to be attached portion 5, 6 of the backing material 43, 38 overlapping a previously attached to the back 2 of the book block 1 section 3, 4 attached.

The overlapping of the sections 3, 4 to be affixed jointly to the back 2 of the book block 1 or the sections 5, 6 to be joined together on the back 2 of the book block 1 can be realized by the feed devices 20, 30 for the back-adhesive material arranged upstream of the first conveyor 60 23, 33 or the feed devices 40, 35 arranged behind the second conveying means 64 for the back-adhesive material 43, 38 in the conveying direction 10 'are offset from one another such that the back-adhesive material 23 for the first section 3 and the back-bonding material 33 for the at least one further section 4 overlapping each other is supplied to the first conveyor 60 and / or the backing material 43 for the second section 5 and the backing material 38 for the at least one further section 6 is supplied overlapping each other to the second conveyor 64.

Of course, both the first section 3 and the at least one further section 4 and the second section 5 and the at least one further section 6 from the respective conveyor 60, 64 in each successive steps are also individually attached to the back 2 of the book block 1. In such a method, the overlapping of the first portion 3 and the at least one further portion 4 or the overlapping of the second portion 5 and the at least one further section 6 can be realized by the intermittent operation of the conveyor 10. A staggered arrangement of the respective feeders 20, 30, 35, 40 is not required in this case.

As in Fig. 2 In detail, in the first feeding device 20 of the right-hand pasting station 16 web-shaped backing material 23 is peeled off from a storage device 22 designed as a roll, cropped on the right side by means of the side cutting device 27, glued by means of the glue jet 28 on the right edge and with the capital ribbon 26 unwound from a ribbon roll 25 glued to a backing material web 24. This is pushed by a trigger device 21 under an upper blade 51 of the cutting device designed as a cross cutter 50, and there cut to length according to the back 2 of the respective book block 1, that is tailored to the thickness 19 of this spine 2. For this purpose, a machine control 87 of the respective extraction device 21, 31 predefines a corresponding cutting length based on the book block data. The first section 3 of the back-adhesive material web 24 formed in this way initially rests on a support table 53 adjoining a lower blade 52 of the cutting device 50. Of course, instead of the backing material web 24 formed from the backing material 23 and the capital band 26, only a backing material 23 without additional capital ribbon 26 can be used.

In the second feeding device 30 of the right-hand pasting station 16, the further web-shaped pasting material 33 is removed from a storage device 32 by means of a take-off device 31 and advanced according to the thickness 19 of the back 2 of the book block 1 under the upper knife 51 of the cutting device 50 located in the upper position , The advanced back-adhesive material 33 is likewise cut to length and thus the further section 4 of the back-adhesive material 33 is produced, which initially rests on the support table 53 adjoining the lower blade 52 of the cutting device 50 (FIG. Fig. 5 ). If the second feed device 30 is in a waiting position, the back-adhesive material 33 coming from the storage device 32 will pass through the draw-off device 31 clamped and ends, as in Fig. 2 shown immediately upstream of the lower blade 52 of the cutter 50.

As in Fig. 2A In detail, in the first feed device 40 of the left pasting station 17, the pasting material 43 peeled off from a storage device 42 formed as a roll is cut off on the left by a side cutter 47, glued by the glue nozzle 48 on the left edge and fed with the capital ribbon 46 unwound from a ribbon roll 45 glued to a backing material web 44. This is pushed by a trigger device 41 under an upper blade 56 of the cutting device 55 and there cut to length corresponding to the back 2 of the book block 1, ie cut to the thickness 19 of the back 2. The second section 5 of the back-adhesive material web 44, which is thus separated from the back-adhesive material web 44, now rests on the support table 58 adjoining a lower blade 57 of the cutting device 55. Of course, instead of the backing material web 44 formed from the backing material 43 and the capital ribbon 46, only a backing material 43 without additional capital ribbon 46 may be used.

In the second feed device 35 of the left rear adhesive station 17, if necessary, the further web-like backing material 38 is pulled off from the storage device 37, which is likewise designed as a roll, by means of a take-off device 36 and pushed under the cutting device 55. The advanced backing material 38 is then likewise cut to length and thus the further section 6 of the back-adhesive material 38 is produced, which first rests on a support table 58 adjoining the lower blade 57 of the cutting device 55 ( Fig. 5 ). If the second feed device 35 of the left rear adhesive station 17 is in the waiting position, the back-adhesive material 38 coming from the storage device 37 is clamped by the draw-off device 36 and ends, as in FIG Fig. 2A shown immediately upstream of the lower blade 57 of the cutting device 55.

Before the cutting device 50, 55 by lowering its upper blade 51, 56 against the respective lower blade 52, 57 a section 3, 5, 4, 6 of the rear adhesive material 24, 44 consisting of the Hinterklebematerial 23, 43 and the capital band 26, 46 adhesively attached thereto or separated from the backing material 33, 38, the suction member 63, 67 of the conveyor 60, 64 is pivoted into the receiving position 61, 65, to finally the first and the second section 3, 5 and if necessary in each case at least one of the other sections 4, 6 between the respective suction member 63, 67 and the support table 53, 58 clamp. After the subsequent cutting to length, the suction element 63, 67 sucks in the first or the second section 3, 5 or the first section 3 and the at least one further section 4 or the second section 5 and the at least one further section 6 and transports them respectively by a pivoting movement by 180 ° in the dispensing position 62, 66. Depending on the spatial arrangement of the receiving position 61, 65 to the dispensing position 62, 66, of course, another pivot angle can be selected for this pivoting movement. The pivoting movement can also take place in one and the same horizontal plane as the feeding of the respective section 3, 5 or the respective sections 3, 4, 5, 6 to the support table 53, 58.

The book blocks 1 are successively, in a vertical arrangement and with the back 2 facing upward, transported by means of two opposing intermittently circulating transport chains 11, 12 of the conveyor 10 to the respective Hinterklebestation 16, 17 of the tandem Hinterklebestation 15 and thereby by lateral guides 13, 14 aligned and supported. During this transport, the backs 2 of the book block 1 to be processed in the gluing device 80 are each provided with the adhesive 8 in a single application process over their entire back length 9.

In the dispensing position 62 of the conveying means 60 of the right rear adhesive station 16, the suction element 63, depending on the previous provision on the support table 53, brings a first section 3 or a first section 3 and at least one further section 4 of the back-adhesive material 23, 33 to the back 2 provided with adhesive 8 of the associated book block 1. Thereafter, the suction member 67 brings in the dispensing position 66 of the conveyor 64 of the left Hinterklebestation 17 at least a second portion 5 or a second portion 5 and at least one further portion 6 of the Hinterklebematerials 43, 38 to the provided with adhesive 8 back 2 of the same book block 1 at , After attaching the respective sections 3, 4, 5, 6, both suction elements 63, 67 pivot back into their respective receiving position 61, 65 in order to produce the next section 3, 5 or the next sections 3, 4 for a subsequent book block 1 of the same format , 5, 6 in the same way. In the tandem Hinterklebestation 15 downstream, a pressing element 86 having Andrückeinrichtung 85 ( Fig. 1 ) are attached to the glued spine 2 of the book block 1 sections 3, 4, 5, 6 of the backing material web 24, 44 and the back-adhesive material 33, 38 pressed uniformly and over the entire surface of the back 2. In this case, the pressure element 86 is designed, for example, as a pressure pad, ie as a flexible cushion of foam or similar materials.

The conveying means 60, 64 of the tandem pasting station 15 differ from the conveying means of a conventional pasting station in that the suction element 63, 67 each has a segmented structure, ie in individual in Fig. 6 . 7 . 8th shown segments 68, 74, each with a contact surface 69, 75 is divided to the back 2 of the book block 1. The length of these segments 68, 74 extending in the conveying direction 10 'of the book block 1 depends on the respective storage device 22, 32, 37, 42 or on the width of the back-adhesive material 23, 33 located in the storage device 22, 32, 37, 42 , 38, 43 from.

Is that in Fig. 7 shown second segment 74 of the suction element 63, for example, not covered with a further portion 4 of the backing material 33, this segment 74, compared to the first section 3 of the Hinterklebematerialbahn 24 occupied first segment 68 of the Saugelements 63 offset so that its contact surface 75 has no contact with the back 2 of the book block 1, while the occupied with the first portion 3, the Hinterklebematerialbahn 24 contact surface 69 in contact with the back 2 of the book block 1 and the attached first section 3. In this case, the actual height difference of the contact surfaces 69, 75 is not critical. Rather, it is essential that the not occupied with a further section 4 of the backing material 33 contact surface 75 of the second segment 74 does not receive adhesive 8 from the back 2 of the book block 1, since such contamination would inevitably lead to disturbances of the book production line 7.

In a format change of the book block 1 to be pasted, the two pasting stations 16, 17 are caused by the machine control 87 (FIG. Fig. 2 . 2A ) via an in Fig. 1 . 3 and 4 only shown by means of a double arrow adjusting device 18 in opposite directions so far adjusted until the respective sections 3, 4, 5, 6 of the Hinterklebematerialbahn 24, 44 and the Hinterklebematerials 33, 38 fit exactly to the back 2 of the format of the previously processed book block 1 different new Book block 1 can be attached.

In the following, several different process sequences will be described, each of which depends on the format of the book block 1 to be processed.

Fig. 3 shows a tandem Hinterklebestation 15 are processed in the book block 1 with a format in which mounted in the right Hinterklebestation 16, the first portion 3 of the Hinterklebematerialbahn 24 and left Hinterklebestation 16, the second portion 5 of the adhesive backing sheet 44 to the back 2 of a book block 1 becomes. For this purpose, by means of the draw-off devices 21, 41 of the two storage devices 22, 42 of the first feeders 20, 40 first each deducted a Hinterklebematerial 23, 43, trimmed by the respective side cutting device 27, 47 and each with a capital band 26, 46 to a Hinterklebematerialbahn 24th 44, which are then pushed under the cutting device 50, 55 and there corresponding to the thickness 19 (FIG. Fig. 2 ) of the back 2 of the respective book block 1 is cut to length. The respective first and second sections 3, 5 of the back-adhesive material web 24, 44, respectively, initially lie on the support table 53, 58 following the respective cutting device 50, 55 and are subsequently conveyed by means of the conveying means 60, 64 (FIG. Fig. 1A ) is attached to the back 2 of the book block 1.

Figure 4 shows a tandem Hinterklebestation 15 are processed in the book block 1 with a format in which in each case a first and a second section 3, 5 of the Hinterklebematerialbahn 24, 44 and another portion 6 of the Hinterklebematerials 38 are attached to the back 2 of the book block 1 , In addition to the already Fig. 3 For this purpose, a back-adhesive material 38 is drawn off from the storage device 37 of the second supply device 35 by means of the removal device 36 of the left-hand back-adhesive station 17, pushed beneath the cutting device 55 adjacent to the back-adhesive material web 44 and corresponding to the thickness 19 (FIG. Fig. 2 ) of the back 2 of the associated book block 1 cut to length. The resulting further section 6 of the backing material 38 is now located together with the second portion 5 of the backing material web 44 on the lower blade 57 of the cutting device 55 adjacent support table 58 and is supported by the conveyor 64 (FIGS. Fig. 1A ) of the left Hinterklebestation 17 attached to the back 2 of the book block 1.

Fig. 5 shows a tandem Hinterklebestation 15 are processed in the book block 1 with a format in which in each case a first or a second section 3, 5 of the Hinterklebematerialbahnen 24, 44 and in each case a further section 4, 6 of the backing material 33, 38 to the back 2 of the book block 1 are attached. In addition to the already Fig. 4 For this purpose, a back-adhesive material 33 is drawn off from the storage device 32 of the second supply device 30 by means of the removal device 31 of the right-hand back-adhesive station 16, pushed under the cutting device 50 next to the back-adhesive material web 24 and corresponding to the thickness 19 (FIG. Fig. 2 ) of the back 2 of the associated book block 1 cut to length. The resulting further section 4 of the back-adhesive material 33 is now located together with the first section 3 of the back-adhesive material web 24 on the lower table 52 of the cutting device 50 adjacent support table 53 and is from the conveyor 60 ( Fig. 1A ) of the right Hinterklebestation 16 attached to the back 2 of the book block 1.

This in Fig. 6 conveying means 60, shown in greater detail, of the right-hand rear-adhesive station 16, shows the suction element 63 divided into the two segments 68, 74 in the dispensing position 62 (FIG. 1A ) for the first and the further back-adhesive portion 3, 4. The first portion 3 having the back-adhesive material 23 and the capital band 26 adhered thereto is received by the first segment 68 of the suction element 63. The second segment 74 of the suction element 63 is in its working position and has received the further section 4 of the back-adhesive material 33. The two sections 3 and 4 overlap slightly in the middle area.

The two segments 68, 74 of the conveyor 60 of the right Hinterklebestation 16 each have a in Fig. 8 shown drilling system 70, 76 with first, the respective contact surface 69, 75 penetrating suction holes 71, 77, each having at least a second, the segments 68, 74, for example, upwardly penetrating bore 72, 78 and in each case a third, the respective first suction holes 71st , 77 and the at least one, second bore 72, 78 connecting third bore 73, 79. The bore system 70, 76 sucks the in Fig. 6 shown sections 3, 4 in the receiving position 61 by means of suction and are these sections 3, 4 by blowing off or releasing in the dispensing position 62 to the provided with the adhesive 8 back 2 of the book block 1 ( Fig. 1A ). In this case, the suction air is sucked through the respective at least one, second bore 72, 78.

By a rotational movement, which is introduced by a pivot shaft 82, the suction member 63 moves between the receiving position 61 and the discharge position 62 back and forth. With an actuator 83 designed, for example, as a pneumatic cylinder, the second segment 74 of the suction element 63 of the right-hand conveyor 60 can optionally be positioned in a working position or a retracted rest position located on the back 2 of the book block 1.

In the FIG. 7 the state is shown in which the conveying means 60 of the right Hinterklebestation 16 has to apply only the first portion 3 of the Hinterklebematerialbahn 24. For this purpose, the second segment 74 is offset by means of the actuator 83 in its rest position, so that it is opposite to the first segment 68 by a segment stroke 84. It is thereby achieved that the second segment 74 does not come into contact with adhesive 8 from the glued spine 2 of the book block 1. The part of the back 2 of the book block 1, which has not been provided by the conveyor 60 with one or more sections 3, 4, is subsequently glued behind with at least one of the conveyor 64 of the left Hinterklebestation 17 section 5, 6.

As FIG. 8 shows, the segments 68 and 74 of the Saugelements 63 are each provided with at least one independently working bore system 70, 76, through which the suction through the respective at least one, second bore 72, 78 deducted, or by which blast air can be introduced. Depending on the width of the sections 3, 4 of the back-adhesive material web 24 or of the back-adhesive material 33, a plurality of bore systems 70, 76 may also be used, as shown in FIG Fig. 7 is shown by way of example with two bore systems 70, 76. The drilling systems 70, 76 may be individually switched on or off by the machine controller 87.

The conveyor 64 of the left Hinterklebestation 17 not shown is analogous, but essentially mirror-image constructed as the above-described conveyor 60 of the right Hinterklebestation 16 and operates in an analogous manner. As an alternative to an analogous structure as the conveyor 60, the conveyor 64 of the left Hinterklebestation 17 also have only a single segment or more than two segments.

The machine controller 87 controls the feeders 20, 30, 35, 40 in use, the position of the displaceable second segments 74, and also the active air / vacuum well systems 70, 76.
