Das grundsätzliche Problem des Einsatzes von aus Metall-Gewebe bestehenden Anpreßbändern besteht darin, daß sich die Schußfäden im Betrieb - ausgehend von den Rändern zur Mitte hin - nach vom, also in Transportrichtung, durchgebogen haben, wodurch die Bandbreite reduziert wird. Die Verbindungsstelle zwischen den Enden des zu einem endlosen Anpreßband verbundenen Metall-Gewebes wird hierdurch in gleicher Weise verbogen und dadurch im Betrieb einer Dreh-Biege-Beanspruchung unterworfen, wodurch die Standzeit des Anpreßbandes negativ beeinflußt wird.The invention relates to a machine according to the preamble of the claim 1. Such a machine is from DE 195 36 007.9 (corresponding GB 2 305 675 A) known. The basic problem of using made of metal mesh pressure tapes is that the Weft threads in operation - starting from the edges towards the middle from, i.e. in the direction of transport, bent, which means the bandwidth is reduced. The junction between the ends of the to an endless pressure band connected to metal fabric bent in the same way and thereby in the operation of a turning-bending stress subjected, making the service life of the pressure belt negative being affected.

In einem Maschinengestell 1 sind eine untere Riffelwalze 2 und eine obere Riffelwalze 3 mittels Wellen 4, 5 drehbar gelagert. Sie weisen zueinander parallele Achsen 6, 7 auf. An ihren Zylinderoberflächen sind sie mit sich parallel zu den Achsen 6, 7 erstreckenden Riffelungen 8, 9 versehen, die im Berührungsbereich 10 der beiden Riffelwalzen 2, 3 miteinander kämmen. Eine der Riffelwalzen 2, 3, und zwar üblicherweise die obere Riffelwalze 3, ist in der Drehrichtung 12 angetrieben, während die andere Riffelwalze, üblicherweise also die untere Riffel walze 2, in Drehrichtung 11 von der anderen Riffelwalze 3 mitgenommen wird. In Drehrichtung 11 bzw. 12, dem Berührungsbereich 10 nachgeordnet, ist eine Leimauftragseinrichtung 13 im Maschinengestell 1 angeordnet, die eine Leim-Auftragswalze 14 aufweist, die gegen die Riffelung 9 der oberen Riffelwalze 3 zustellbar ist. Die Auftragswalze 14 ist um eine Achse 15 drehbar.In a machine frame 1 there are a lower corrugating roller 2 and an upper one Corrugated roller 3 rotatably supported by means of shafts 4, 5. They point to each other parallel axes 6, 7. They are with them on their cylinder surfaces parallel to the axes 6, 7 extending corrugations 8, 9 provided in Comb the contact area 10 of the two corrugated rollers 2, 3 with one another. One of the corrugating rollers 2, 3, usually the upper corrugating roller 3, is driven in the direction of rotation 12, while the other corrugating roller, So usually the lower corrugation roller 2, in the direction of rotation 11 of the other corrugating roller 3 is taken. In the direction of rotation 11 or 12, Downstream of the contact area 10 is a glue application device 13 arranged in the machine frame 1, the a glue application roller 14th has, which is adjustable against the corrugation 9 of the upper corrugating roller 3. The application roller 14 is rotatable about an axis 15.

Im oberen Bereich der oberen Riffelwalze ist eine Anpreß-Einrichtung 16 vorgesehen, die eine Umlenkwalze 17, eine Spannwalze 18 und ein Anpreßband 19 aufweist. Die Umlenkwalze 17 und die Spannwalze 18 sind mittels Wellenzapfen 20 bzw. 21 in Lagern 22 bzw. 23 des Maschinengestells 1 jeweils um eine Achse 24 bzw. 25 frei drehbar gelagert, sind also nicht angetrieben. Alle Achsen 6, 7, 15, 24, 25 verlaufen parallel zueinander. Ausgestaltungen für die Spannwalze 18 sind allgemein bekannt, beispielsweise aus der DE 44 20 726 A (entsprechend US-PS 5 632 850). Ein Spannen des Anpreßbandes 19 erfolgt durch Verschiebung der Spannwalze 18 parallel zur Ablauftangente 27 in Richtung 28.A pressure device 16 is located in the upper area of the upper corrugating roller provided that a deflecting roller 17, a tension roller 18 and a pressure belt 19 has. The deflection roller 17 and the tension roller 18 are by means of shaft journals 20 and 21 in bearings 22 and 23 of the machine frame 1 are each freely rotatable about an axis 24 or 25, that is not powered. All axes 6, 7, 15, 24, 25 run parallel to one another. Designs for the tension roller 18 are generally known, for example from DE 44 20 726 A (corresponding to US Pat. No. 5,632,850). On Tensioning the pressure belt 19 is carried out by moving the tensioning roller 18 parallel to the drain tangent 27 in the direction 28.

Wie Fig. 1 entnehmbar ist, liegt das Anpreßband 19 über einen Umschlingungswinkel g von etwa 90° gegen die Riffelung 9 der oberen Riffelwalze 3 an und läuft drehrichtungsgleich mit dieser entsprechend dem Richtungspfeil 26 um. Das Anpreßband 19 läuft von der oberen Riffelwalze 3 entsprechend der Ablauftangente 27 ab, die identisch mit der Einlauftangente des Anpreßbandes 19 auf die Spannwalze 18 ist.As can be seen in FIG. 1, the pressure band 19 lies over a wrap angle g of about 90 ° against the corrugation 9 of the upper corrugating roller 3 starts and runs in the same direction as the direction of the arrow 26 um. The pressure belt 19 runs from the upper corrugating roller 3 accordingly the expiration tangent 27, which is identical to the inflow tangent of the pressure belt 19 on the tension roller 18.

Das Anpreßband 19 ist als feinmaschiges, zugfestes Sieb-Band ausgebildet, und zwar als Gewebe, wie es im einzelnen in den Figuren 2 bis 5 dargestellt ist. Es besteht aus in seiner dem Richtungspfeil 26 entsprechenden Längsrichtung 29 verlaufenden Kettfäden 30 und quer hierzu verlaufenden Schußfäden 31. Die Kettfäden 30 sind jeweils in Paaren von drei Kettfäden 30a, 30b, 30c vorgesehen, wobei diese Paare von Kettfäden 30a, 30b, 30c eine Breite a haben, die größer ist als der Abstand b benachbarter Paare von Kettfäden. Die beiden äußeren Kettfäden 30a, 30c jedes Paares von Kettfäden verlaufen gleichsinnig, d.h. sie sind jeweils über die gleiche Seite eines Schußfadens 31 geführt, während der mittlere Kettfaden 30b jeweils entgegengesetzt geführt ist, wie insbesondere den Fig. 2 bis 4 entnehmbar ist. Dadurch, daß die drei Kettfäden 30a, 30b, 30c pro Paar von Kettfäden 30a, 30b, 30c in dieser Weise vorgesehen und geführt sind, wird eine symmetrische Einspannung des jeweiligen Schußfadens 31 erreicht.The pressure belt 19 is designed as a fine-mesh, tensile sieve belt, namely as a fabric, as shown in detail in Figures 2 to 5 is. It consists of the arrow 26 corresponding to the directional arrow Longitudinal direction 29 extending warp threads 30 and transverse to this Weft threads 31. The warp threads 30 are each in pairs of three warp threads 30a, 30b, 30c provided, these pairs of warp threads 30a, 30b, 30c have a width a that is greater than the distance b between adjacent pairs of Warps. The two outer warp threads 30a, 30c of each pair of warp threads run in the same direction, i.e. they are each on the same side of one Weft 31 guided, while the middle warp thread 30b each opposite is guided, as can be seen in particular from FIGS. 2 to 4. Because the three warp threads 30a, 30b, 30c per pair of warp threads 30a, 30b, 30c are provided and guided in this way, a symmetrical Clamping of the respective weft thread 31 reached.

Dieser Verlauf der Kettfäden 30a bis 30c wechselt von einem zum anderen benachbarten Paar von Kettfäden 30a bis 30c ab, wie insbesondere den Fig. 2 und 3 entnehmbar ist. Dies heißt, daß dann, wenn - bezogen auf die Draufsicht in Fig. 2 - der mittlere Kettfaden 30b - in Fig. 2 - über einen Schußfaden 31 verläuft, der mittlere Kettfaden 30b des benachbarten Paares von Kettfäden - wiederum bezogen auf die Draufsicht in Fig. 2 - unterhalb des Schußfadens 31 durchgeführt ist. Entsprechendes gilt umgekehrt für die beiden äußeren gleich verlaufenden Kettfäden 30a und 30c jedes Paares von Kettfäden.This course of the warp threads 30a to 30c changes from one to the other adjacent pair of warp threads 30a to 30c, as in particular the Fig. 2 and 3 can be removed. This means that if - in relation to the Top view in Fig. 2 - the middle warp thread 30b - in Fig. 2 - over a Weft thread 31 runs, the middle warp thread 30b of the adjacent pair of warp threads - again based on the plan view in Fig. 2 - below of the weft thread 31 is carried out. The reverse applies accordingly for the two outer identical warp threads 30a and 30c each Pair of warp threads.

Wie Fig. 5 entnehmbar ist, besteht jeder Kettfaden 30a bis 30c aus sechs Litzen 32, die miteinander verseilt, also verdrillt, sind, was in den Figuren 2 und 4 zeichnerisch angedeutet ist. Der Durchmesser c jeder Litze 32 liegt im Bereich von 0,2 mm. Der Durchmesser c der Litzen 32 kann zur Verschleißminderung gegebenenfalls auch kleiner als 0,2 mm, nämlich im Bereich von 0,15 bis 0,2 mm, liegen. Daraus ergibt sich, daß der Durchmesser d jedes Kettfadens 30a bis 30c im Bereich von 0,6 mm liegt. Die Litzen 32 bestehen jeweils aus Stahldraht. Aufgrund der Verseilung sind die einzelnen Kettfäden 30a bis 30c einerseits sehr zugfest und andererseits sehr biegsam. Für das Verhältnis des Abstandes b der Paare von Kettfäden 30a bis 30c zum Durchmesser d der einzelnen Kettfäden 30a, 30b, 30c gilt 1,2 d ≥ a ≥ 0,3 d.5, each warp thread 30a to 30c consists of six Strands 32, which are twisted together, that is to say twisted, are what is shown in FIGS and 4 is indicated in the drawing. The diameter c of each strand 32 lies in the range of 0.2 mm. The diameter c of the strands 32 can be used to reduce wear possibly also less than 0.2 mm, namely in the area from 0.15 to 0.2 mm. It follows that the diameter d of each warp thread 30a to 30c is in the range of 0.6 mm. The strands 32 each consist of steel wire. Because of the stranding, the individual Warp threads 30a to 30c on the one hand very tensile and on the other hand very flexible. For the ratio of the distance b of the pairs of warp threads 30a to 30c applies to the diameter d of the individual warp threads 30a, 30b, 30c 1.2 d ≥ a ≥ 0.3 d.

Die Schußfäden 31 bestehen aus einem Werkstoff, der weicher ist als der Werkstoff der Kettfäden 30a bis 30c, so daß sich die Kettfäden 30a bis 30c unter Bildung von leichten Kerben 33 in den Schußfäden 31 gleichsam in letztere eingraben, so daß ein Verrutschen der Kettfäden 30a bis 30c in Richtung der Schußfäden 31 zusätzlich unterbunden wird. Als Werkstoff für die Schußfäden 31 und die Kettfäden 30a bis 30c kommen hochlegierte Chrom-Nickel-Stähle in Betracht, die von ihrer Legierungszusammensetzung her identisch sind, so daß eine Spannungskorrosion ausscheidet. Die unterschiedliche Festigkeit wird in bekannter Weise durch die Art des Drahtziehens und die hierbei erfolgenden Behandlungen erreicht, die in der Praxis bekannt sind. Die freien Enden 34 der Schußfäden 31 sind kugelkalottenförmig ausgebildet, d.h. abgerundet, um die Gefahr einer Verletzung auszuschließen.The weft threads 31 are made of a material that is softer than that Material of the warp threads 30a to 30c, so that the warp threads 30a to 30c forming slight notches 33 in the weft threads 31 as it were bury the latter so that the warp threads 30a to 30c slip in Direction of the weft threads 31 is additionally prevented. As a material for the weft threads 31 and the warp threads 30a to 30c come high-alloyed Chromium-nickel steels are considered by their alloy composition are identical, so that stress corrosion is eliminated. The different strength is known in the manner of the type of Wire drawing and the treatments that take place here, which in the Practice are known. The free ends 34 of the weft threads 31 have the shape of a spherical cap trained, i.e. rounded to the risk of injury excluded.

Die Schußfäden 31 bestehen aus stabartigen Drähten, deren Durchmesser e im Bereich von 1,0 mm liegt. Der Abstand f benachbarter Schußfäden 31 liegt im Bereich von 1,0 bis 1,5 mm und bevorzugt im Bereich von 1,1 bis 1,2 mm.The weft threads 31 consist of rod-like wires whose diameter e is in the range of 1.0 mm. The distance f between adjacent weft threads 31 is in the range of 1.0 to 1.5 mm and preferably in the range of 1.1 to 1.2 mm.

Das Anpreßband 19 wird aus einem endlichen Metall-Gewebe-Band hergestellt, dessen Enden im Bereich eines Schußfadens 31 auf übliche Weise nach dem Stand der Technik, beispielsweise durch eine Lötverbindung, miteinander verbunden werden. Alternativ können an den Enden der Kettfäden Ösen angeschweißt sein, durch die ein Stab gesteckt wird.The pressure tape 19 is made from a finite metal-fabric tape, whose ends in the region of a weft thread 31 in the usual way according to the prior art, for example by a soldered connection, be connected to each other. Alternatively, at the ends of the warp threads Welded eyelets through which a rod is inserted.

Die Wirkungsweise der Maschine ist wie folgt:The machine works as follows:

In den Berührungsbereich 10 zwischen der unteren und der oberen Riffelwalze 2, 3 läuft eine Papierbahn 35 ein, die durch die Riffelungen 8,9 mit einer Wellung 36 versehen wird. Die Spitzen 37 der jeweiligen Wellung 36 werden in der Leimauftragseinrichtung 13 mit Leim versehen. Die übrigen Bereiche der gewellten Papierbahn 35 werden nicht beleimt. Über die Umlenkwalze 17 wird eine Kaschierbahn 38 zugeführt, die ebenfalls aus Papier besteht und die gleiche Breite hat wie die Papierbahn 35. Diese Kaschierbahn 38 wird gegen die Außenseite 39 des Anpreßbandes 19 eingeführt und in den durch den Umschlingungswinkel g definierten Anpreßbereich 40 des Anpreßbandes 19 gegen die Spitzen 37 der in der Riffelung 9 der oberen Riffelwalze 3 liegenden, gewellten Papierbahn 35 gedrückt und mit dieser verbunden. Das Anpreßband 19 preßt hierbei mit seiner Außenseite 39 die Kaschierbahn 38 gegen die gewellte Papierbahn 35.In the contact area 10 between the lower and the upper corrugating roller 2, 3 a paper web 35 runs in, which is formed by the corrugations 8, 9 a corrugation 36 is provided. The tips 37 of the respective corrugation 36 are provided with glue in the glue application device 13. The remaining Areas of the corrugated paper web 35 are not glued. Via the deflection roller 17 a liner 38 is fed, which is also made of paper exists and has the same width as the paper web 35th This liner 38 is inserted against the outside 39 of the pressure band 19 and in the pressing area 40 defined by the wrap angle g Pressure band 19 against the tips 37 of the corrugation 9 of the upper Corrugated roller 3 lying, corrugated paper web 35 pressed and with this connected. The pressure band 19 presses with its outside 39 Laminating web 38 against the corrugated paper web 35.

Da die obere Riffelwalze 3 in üblicher Weise, beispielsweise auf ca. 170°C, geheizt wird, verdampft das im an den Spitzen 37 der Wellung 36 befindlichen Leim 41 enthaltene Wasser und entweicht mindestens zum Teil durch die Kaschierbahn 38 und das siebartige, gewebte Anpreßband 19, wie mit den Strömungspfeilen 42 in Fig. 6 angedeutet ist.Since the upper corrugating roller 3 in the usual way, for example at about 170 ° C. is heated, that evaporates in the located at the tips 37 of the corrugation 36 Glue 41 contained water and escapes at least in part the liner 38 and the screen-like, woven pressure tape 19, as with the flow arrows 42 in Fig. 6 is indicated.

Die fertig verleimte, einseitig mit einer Kaschierbahn 38 kaschierte Wellpappebahn 43 läuft in Richtung der Ablauftangente 27 zusammen mit dem Anpreßband 19 von der oberen Riffelwalze 3 ab und wird mit dem Anpreßband 19 teilweise um die Spannwalze 18 herum geführt. Von dort wird sie in Abziehrichtung 44 einer Aufwickeleinrichtung zugeführt.The fully glued corrugated cardboard, laminated on one side with a liner 38 43 runs in the direction of the drain tangent 27 together with the Pressure belt 19 from the upper corrugating roller 3 and is with the pressure belt 19 partially guided around the tension roller 18. From there they are fed to a take-up device in the pull-off direction 44.

Die Heizung der Papierbahnen 35, 38 muß nicht über die Riffelwalze 3 erfolgen. Sie kann alternativ oder fakultativ auch durch eine innerhalb des Anpreßbandes 19 zwischen Umlenkwalze 17 und Spannwalze 18 angeordnete, in Fig. 1 gestrichelt angedeutete Heizung 45 vorgenommen werden.The heating of the paper webs 35, 38 does not have to take place via the corrugating roller 3. Alternatively or optionally, it can also be carried out within the Pressure belt 19 arranged between deflection roller 17 and tension roller 18, 1 indicated by dashed lines in FIG. 1.
