Abstract
The process for joining bundled paper layers 13 is based on the injection of binder into the layers. This binder injection 15 can consist of pressing binder into paper layers preperforated by needles 22, perforation either taking place beforehand or in the same operation by means of injection through hollow or tubular needles 22. Another possibility of binder injection 15 involves the shooting in of binder droplets. The after-treatment 16 of the paper layers can consist of pressing and/or ultrasonic action. Optionally binder injection only takes place into the inner pages 52 of the paper layer 13 without the cover page 51 and middle page 53.

Process for the adhesive binding of paper layers.
The invention relates to a process and to an apparatus for the adhe-sive binding of paper layers.
Processes for joining paper layers have been known for decades.
They form an essential part of bookbinding. Innovations in connection with the mechanical binding of paper layers became necessary with the arrival of high-performance printing plants able to produce up to 100,000 printed products every hour.
Wire stitching and adhesive binding have proved satisfactory for the mass binding of paper layers, such as is required in printing works. Wire stitching is very important for the joining of printing material in booklet or brochure form. Rotary wire stitchers have a high efficiency, but are relatively expensive. A stitched copy can have up to 100 pages. In the case of rotary wire stitchers the wire staples are forced through the spread out paper bundle against an abutment and without any locking r~ch~ni sm. The paper is folded after stitching.
Single or individual wire stitchers have a lower capacity per unit of time than rotary wire stitchers and are also expensive. However, the product can have over 300 pages and individual wire stitchers have an abutment with a locking -ch~ni~ .
An advantage of wire stitching is the possibility of completely open-ing the booklet. There is no closed folded edge, which covers part of the printed information. However, a disadvantage of wire stitching is the material application through the staples in the back, which limits the stackability of the products. Additional costs also result from the selection, storage and processing of the appropriate wire material. There are also limits on the reliability of wire stitching, particularly in the case of thick paper layers having more than 200 pages.

'~_ Adhesive binding is a further paper binding method, which is part-icularly used in bookbinding. When this method is used, the paper is initially bundled, overcut and subsequently its back is glued.
Although this method has long been known, problems still occur.
Decisive points in connection with the success of this binding method are e.g. the paper quality, the nature of the unit (text or text with pictures), the nature of the adhesive (dispersion or hot melt adhesive) and the wetability of the printed paper. The drying speed is particularly critical in this method, where the back is wetted.
This is a function of the thickness of the adhesive applied, the absorptivity and the degree of paper gluing. For e~ample, air flows or high frequency electric fields are used for speeding up drying.
The adhesive can be applied either cold or at elevated temperature.
It has proved advantageous for increasing the adhesion surface to provide the back to be glued with channels or grooves by means of a cutter equipped with equidistantly positioned knives. It must be ensured that the adhesive applied as a melt or dispersion can be deposited in an optimum manner on the edge of the sheet.
Another adhesion process is fold adhesion. In this process the ind-ividual paper layers are initially individually applied with strip or spot-like adhesion points or splices and are subsequently joined under pressure, cf. e.g. German Patent 35 27 660 C2. Fold adhesion makes it possible to simultaneously join a ma~imum of 32 pages at the normal printing speed. However, the process requires an additi-onal operation, together with a complicated, individual guidance of the individual paper sheets. It must in particular be ensured that the paper layers prepared for joining are not in premature cont-act. In this connection reference is made to an interesting solution by I. Kobler, described in Swiss Patent 665 389 A5. Smearing of the adhesive applied by cyclically pressing the paper web against an adhesive-applying roller is prevented in that the paper web is guided by guide rollers or pulleys, which have cavities corresponding to the adhesive strips.
~ 3 Another disadvantage of fold adhesion is that the printed product cannot be completely opened in the fold. Pictorial information can be lost in the case of double-sided illustrations in booklets and brochures.
Thus, the problem exists of developing a process permitting a simultaneous adhesion of paper layers, without having to accept the disadvantages such as the cutting open of the back prior to gluing or the gluing of the individual pages prior to joining.
This problem is solved in that adhesive is locally injected into the paper layers. Binder injection takes place either following a preperforation of the paper layers and binder application through hollow or tubular needles, or by directly shooting droplets into the paper layers. As a result of binder injection, in analogy to thread or wire stitching, a the paper layers can be joined after cutting and putting into order the individual sheets and optionally even following folding.
In accordance with one embodiment of the invention, a method is provided for joining collected or bundled paper layers in the form of booklets, brochures or books by injecting an adhesive-containing binder into the paper layers, wherein the binder is injected into the paper layers by the shooting in of droplets of binder into the paper layers.
In accordance with another embodiment of the invention, an apparatus is provided for joining paper layers in the form of booklets, brochures or books for performing the method of the invention comprising a droplet shooting-in apparatus having a shooting-in nozzle and an abutment, the nozzle and abutment being arranged in such a way that the paper layers to be joined are positionable between the nozzle and the abutment.
Thus, the proposed process differs significantly from existing adhesive binding process, in which the adhesive is applied to the cut open back. Although these standard methods permit an B
- 3a - i7 ~
optimum spreading of the adhesive, e.g. through the application of grooves and the open back can also be subject to rapid adhesive drying, e.g. by hot air supply, irradiation, etc., but back gluing, as stated, requires a consideration amount of preparation.
The novel binder injection process according to the invention also differs significantly from the aforementioned fold adhesion. Whereas in the latter case, the individual sheets have to be individually provided with an adhesive and care must be taken to prevent any uncontrolled contact thereof prior to joining, in the novel process the binder is applied centrally to a sorted and ordered paper stack.
There are various possibilities for carrying out the binder injection process and the binder can in particular be injected into the paper 2 ~ 7 ~
.,_ layers following a preperforation, or can be shot into said layers in droplet form.
The principle of shooting binder droplets into paper layers is novel.
It is based on the high-pressure water or water jet cutting method, which has been successfully used for separating solid materials, such as rock, metal, wood, plastic, etc. In this method the water is initially brought up to a pressure of several kbar and is delivered intermittently to the cutting nozzle. The ejected water droplets have an initial velocity of 600 to 1000 m/sec.
The water jet cutting of paper has been investigated. Contrary to e~pectations, a water jet striking paper layers dissolved after a short distance, the medium penetrating the paper layers and bringing about a swelling thereof, accompanied by an unsatisfactory cut qua-lity. It is not therefore surprising that the water jet cutting method has not acquired any significance in the paper processing industry. It is therefore not obvious to use this method in conj-unction with the binding of paper layers. However, the inadequacies of water jet cutting of paper, namely the disadvantageous consequences of wetting, swelling and mottling of the material are desired in connection with adhesion or bonding.
Compared with wire stitching, the two embodiments of the binder injec-tion process have a number of advantages. There is no need for a precisely adjusted, wear-prone mech~n;~ for pressing in and bending over the staples. It is merely necess~ry to slightly press the adhe-sive in the area round the splice. Apart from the paper, no additio-nal material (staple wire) has to be stored and supplied. The method is very advantageous from the recycling standpoint, because the paper has no extraneous matter (wire staples) and the necessary adhesive quantitiy is negligibly small. It is possible to simultaneously process multilayer products. Foldability is improved by the moisten-ing of the fold region with the binder.

However, various after-treatment processes which have proved advant-ageous in connection with adhesive binding, such as drying in an air flow, are not appropriate for the novel binder injection process, because the splice is not accessible.

The printing material is subsequently ordered and is then conveyed on in the form of bundled paper layers 13, optionally as a scale or flake flow 14. The printed matter then reaches the binder injection apparatus 15. Binder injection can comprise pre-perforation with subsequent injection or the shooting in of droplets.

Fig. 2 shows a first variant of an apparatus for injecting binder into paper layers. To a strip or bar 21 are fitted e.g. comb-like needles 22, which bring about the preperforation 23 (fig. 2a) of the paper layers 13 by means of the needle pressing device 29.
Instead of perforation being carried out simultaneously with a needle comb 24, in which a plurality of needles 22 is located on a bar 21, perforation can take place sequentially with one or a few needles 22. Following perforation the binder is taken from the binder reser-voir 25 and is applied by the binder pressing device 26 (fig. 2b).
To this end the binder is either pressed directly into the perfora-tions 23, or tubular or hollow needles 31 are used. During perfora-tion and optionally also for binder injection, the paper layers 13 are appropriately pressed by a pressing device 27 against an abutment 28, so that perforation takes place in controlled manner and there is also no hinderance to the extraction of the needles.
As shown in fig. 3, as a function of the characteristics of the paper layers, the perforation and injection of the binder can be carried out in the same operation. This is possible if the binder injection can be carried out through hollow or tubular needles 31 at the time of perforation.
Another possibility of injecting the binder into the paper layers consists of the shooting through of liquid droplets. As stated, this method is based on the water jet cutting principle.
Fig. 4 shows an apparatus, such as is used for water jet cutting.
A cylindrical casing 41 contains a booster plunger 42. As a result of its hydraulically controlled movement, the liquid medium supplied intermittently by the recharging valve 43 is intermittently shot into the material to be processed via nozzle 44 at a pressure of several kbar. The ejected droplets have an initial velocity of 600 to 1000 m/sec.
For example with the aid of a pressing device 27, the paper layers 201~7~
",~, 13 are prepressed, so that the kinetic energy of the medium droplets is not used up for the echAnical displacement of the paper layers 13 and is instead used for shooting through the droplets. As a result of the pressing, the paper layers are given a wood-like consistency (wood, e.g. plywood can, as known, be very adequately cut by water jets).
It is obvious that in this way water, even if it contains a little adhesive, can be shot into or through the fold. The paper layers 13 are slightly moistened. Binder is also introduced into the paper layers in the case of a dispersive or colloidal addition to the "cutting water". As only a little binder is required, the binder concentration in the water jet can be kept very low, which prevents any risk of the nozzle clogging or eroding.
The paper layers are locally damaged in both binder injection modes.
However, this damage can be rendered invisible, in that both the cover page of the booklet and possibly also the middle page are appl-ied following binder injection. The binder passing out of the injec-tion holes during the after-treatment ensures the adhesion of the cover and middle pages. A corresponding apparatus is shown in fig.
5.
The cover page 51, the inner pages forming a unit 52 and without the middle page, as well as the middle page 53 are supplied individ-ually. The binder is injected in the indicated manner into the unit 52. The three parts 51,52,53 are then joined together and after-tre-ated, e.g. by means of an after-treatment device 16,28.
In the case of a very sparing use of the binder, it should be possible to render the splice loadable by even short pressing. Another prom-ising possibility for the drying, hardening and therefore quality increase of the splice consists of the use of ultrasonics, such as have been successfully used for joining plastics.

The stackability of the products can be improved in that, before or during folding, the fold is moistened slightly. There is no need for such a treatment in the present process, because moistening occurs in conjunction with the binder injection.
