Definitions
- the invention relates to a device for distributing the successive products of a product stream, in particular the folded products formed by a cross cutter by subdividing a material strand, to two partial streams according to the preamble of claim 1.
- the EP 0054963 A1 already shows a splitting arrangement with in the transport plane of the product flow fixed wedges, which are arranged transversely to the transport direction side by side.
- the two side surfaces of the wedge are associated with two cam flanks flanking them, which have cams and recesses in an area between the wedges.
- Each cam on the one cam roller is assigned an area on the other cam roller as a counter-holding surface on which no cam is provided and over which the local conveyor belt is guided.
- the conveyor belts thus run laterally next to the cams through the splitting device. In these areas of the respective bands, the products passing through the splitting device can therefore not be supported and deflected by the cams.
- this object is achieved in that the wedge assembly between two flanking baffles engages, which together with the wedge assembly limit a fork, wherein the baffles have slots at which they are swept alternately by the associated cams of the respective adjacent cam roller, so that in each case the sweeping cams and the unconfined baffle form a supply for a partial flow associated with a ribbon line.
- the products can be guided safely and over their entire width.
- the products of the splitting device can be supplied safely and undamaged even at high speeds, or removed from it. Because the necessary guidance of the products at their lateral edges in the product leading to the splitting device or away from her band line can be guaranteed even with product widths that correspond to the distance of the outer bands. Overall, such a paper jam can be avoided even if, in a known device, the non-deflectable lateral product edges would collide with the tip of the fixed wedge assembly.
- the cam rollers have, over their length, a plurality of closely spaced cams and the baffles have a plurality of slots associated with the cams, e.g. over 10 to 20 or more cams and slots.
- the cam rollers can advantageously each have continuous shafts, on each of which a plurality of cams provided with a number of cams are clamped.
- the wedge arrangement comprises a number of wedges extending at least over the width of the cam rollers provided with cams.
- the closely spaced thin cams guide the product safely over the entire width of the product over the wedge or the wedge arrangement into the respective continuous strip line.
- the wedge arrangement and the baffles through which the cams penetrate limit the free space of the products and prevent folding and damaging of the products.
- the wedge arrangement may comprise one or more wedges.
- the wedge or wedges can lie either with their wedge tip behind the painted off by the two cam rollers area.
- the close spacing of the split cams ensures that neither the product leading edge nor the product end can come into contact with the fixed wedge tip.
- the wedge tip can also be slotted to the cam rollers as the baffles, so that the one or more wedges can also be penetrated by the cams of the cam rollers and offer with their side walls an additional support of the products inwards.
- the stripline does not need to be passed through the device, but extends outside the device and then resumes product guidance so as to provide good guidance in the path formed by the baffles, cams, and optionally the wedge sidewalls, without the needles described above danger of paper jam arises.
- the the FIG. 1 underlying device is used to process web material, preferably in the form of printed substrate webs of paper, longitudinally folded, arcuate products, such as newspapers, etc.
- the web material 1, 2 in the form of individual webs or in the form of several superimposed sheets comprehensive web packages the formers 3, 4 fed to a former arrangement and thereby provided with a longitudinal fold.
- Each folding hopper 3, 4 is followed by a traction device 5, 6, which pulls the associated web material 1 and 2 via the associated former 3 and 4 respectively.
- the drawbars 5, 6 consist of two cooperating rollers, one of which is driven, and which guide and guide rollers 7, 8 before and / or can be arranged downstream.
- the longitudinally folded material which is referred to below as strands 1a and 2a, is then subdivided into arcuate products by means of a cross-cutting device 9.
- the resulting product stream is then divided by a splitting device 10 into two sub-streams and following the splitting of two of these downstream strip lines 11, 12 to a Product delivery 13 transported.
- a braking device 14 with downstream paddle wheel 15 is assigned to each of these.
- the paddle wheels 15 are underlined by delivery belts 16, on which the products are stored in the form of a scale flow.
- the above-mentioned units of the drawbars 5, 6 downstream are arranged in a machine frame 17, in which the running of the formers 3, 4 strands 1a, 2a enter.
- the machine frame 17 has two side walls on which said devices are mounted.
- a mounting wall 18 is placed, which the folding hoppers 3, 4 associated Bahnzeitorgane 19 such as guide and / or turning bars etc. carries. These are arranged in a flying position and accordingly accessible from their end remote from the mounting wall 18.
- the running from the lower former 3 strand 1 a runs without deflection down.
- the running of the upper former 4 strand 2a which is referred to in practice as so-called. Balloon strand, is deflected laterally for bypassing the lower Former 1.
- the strand 2a must be performed by the building wall 18, which is provided for this purpose with a feed-through window 20.
- the mounting wall 18 is arranged so that the flying guide elements 19 are easily accessible from the side indicated by an arrow 21 web feed ago.
- the mounting wall 18 is offset laterally relative to a median plane of the former arrangement. The direction of the web feed depends on the arrangement of upstream devices and may therefore change. If the web feed takes place from the opposite side of the arrow 21, the mounting wall 18 must be arranged on the other side of the former arrangement, as in Fig. 1 indicated by broken lines.
- the web guide 2a assigned to this strand must also have the plane defined by the common transport plane of the coplanar strands symmetrical to the solid lines drawn arrangement lie.
- the Auslegeb section 16 instead of the products, as interpreted in the illustrated embodiment, to the right, to the other side to the left.
- the machine frame 17 consists of a plurality of mutually arranged modules which are rotatable by 180 ° from each other and in the respective end positions are fixed to each other. Two modules are practically sufficient. Accordingly, in the illustrated example, two modules, namely an upper module 22 and a lower module 23 are provided.

- the brake devices 14, paddle wheels 15 and delivery rails 16 of the lower module are likewise assigned their own drive motors 30, 31 and 32, 33 and 34, 35, respectively.
- the lower module 22 accordingly contains six independent drive motors 30-35. The mutual independence of the drive motors 26-35 facilitates the control and the achievement of any desired lead or lag, which has an advantageous effect on the accuracy and gentle operation.
- the strip lines 11, 12 traverse the parting line 24 in the example shown.
- the strips of the strip lines 11, 12 must therefore be removed before one of the modules 22, 23 is rotated.
- the provided in the region of the parting line 24 inner tape rolls 36 of the tape lines 11, 12 are arranged symmetrically to the above-mentioned working level, so that after the rotation of one of the modules 22, 23 there is the same band history, as before the rotation.
- the running of the formers 3, 4 strands 1a, 2a can be transported after the union depending on the funnel arrangement lying on one another or lying side by side.
- all the organs and devices are formed by the junction 37 at downstream two-lane, ie so that if necessary two strands can run side by side.
- the side walls of the racks of the modules 22, 23 are correspondingly far away from each other, so that there is the required working width. This here mentioned two-lane is according to the facilities Figures 2 - 8 based.
- Cutting device 10 shown consists of two parallel, circumferentially juxtaposed cutting cylinders, each having two juxtaposed, each associated with a track knife 39.
- the cutting cylinders 38 are each provided in the region of their respective track associated lengths with circumferential, interrupted by the blades 39 grooves in which opposite the respective adjacent lands radially projecting, from a compressible material, preferably Vulkollan, existing strips are pressed, the minisickung cause the passing material. This ensures that the newly created at each cut web start does not fan out even in Incallagiger products.
- the length of the products is dependent on the diameter of the cutting rollers 38.
- the cutting cylinder 38 In the event of a change in length, the cutting cylinder 38 must be replaced.
- the cutting cylinders 38 are mounted in lateral Exzenterlagen 41. By rotating the eccentric sliders 41, therefore, the center distance can be changed.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Verteilen der aufeinanderfolgenden Produkte eines Produktstroms, insbesondere der durch einen Querschneider durch Unterteilung eines Materialstrangs gebildeten Falzprodukte, auf zwei Teilströme gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for distributing the successive products of a product stream, in particular the folded products formed by a cross cutter by subdividing a material strand, to two partial streams according to the preamble of claim 1.
Bei den bekannten Anordnungen dieser Art, sog. Splittingvorrichtungen ist jeweils eine schwenkbare Zunge vorgesehen, welche die aufeinanderfolgenden Produkte abwechselnd dem einen oder anderen Teilstrom zuführt. Die Zunge stellt ein gegenüber den bewegten Produkten stationäres Bauteil dar. Aufgrund der Relativbewegungen zwischen den Produkten und der Zunge kann es daher zu Markierungen auf den Produkten und bei der Verarbeitung von Druckprodukten zum Abschmieren von Farbe und dergleichen kommen. Die bekannten Anordnungen erweisen sich daher als nicht produktionsfreundlich genug.In the known arrangements of this type, so-called. Splittingvorrichtungen a pivotable tongue is provided in each case, which alternately feeds the successive products to one or the other partial flow. The tongue is a stationary component with respect to the moving products. Therefore, due to the relative movements between the products and the tongue, there may be marks on the products and in the processing of printed products to smear paint and the like. The known arrangements therefore prove to be not sufficiently production-friendly.
Die
Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, dass die Produkte geschont und eine hohe Produktqualität gewährleistet werden.On this basis, it is therefore the object of the present invention to improve a device of the type mentioned with simple and inexpensive means so that the products are protected and high product quality guaranteed.
Erfindungsgemäß wird bei einer gattungsgemäßen Vorrichtung mit einer in der Transportebene des Produktstroms fest angeordneten Keilanordnung die zwischen zwei sie flankierenden, symmetrisch zur mittleren Arbeitsebene angeordneten Nockenwalzen eingreift, diese Aufgabe dadurch gelöst, dass die Keilanordnung zwischen zwei sie flankierende Leitbleche eingreift, die zusammen mit der Keilanordnung eine Weggabelung begrenzen, wobei die Leitbleche Schlitze aufweisen, an denen sie abwechselnd von den Schlitzen zugeordneten Nocken der jeweils benachbarten Nockenwalze durchgreifbar sind, so dass jeweils die durchgreifenden Nocken und das nichtdurchgriffene Leitblech eine Zuführung für eine einem Teilstrom zugeordnete Bandleitung bilden.According to the invention, in a generic device with a fixed in the transport plane of the product flow wedge arrangement between two flanking them, arranged symmetrically to the central working plane cam rollers engages, this object is achieved in that the wedge assembly between two flanking baffles engages, which together with the wedge assembly limit a fork, wherein the baffles have slots at which they are swept alternately by the associated cams of the respective adjacent cam roller, so that in each case the sweeping cams and the unconfined baffle form a supply for a partial flow associated with a ribbon line.
Zwischen den Leitblechen und den Nocken können die Produkte dabei sicher und über ihre ganze Breite geführt werden. Dabei könenn die Produkte der Splittingvorrichtung auch mit hohen Geschwindigkeiten sicher und unbeschädigt zugeführt bzw. aus ihr abtransportiert werden. Denn die dafür nötige Führung der Produkte an ihren seitlichen Produktkanten in der zur Splittingeinrichtung führenden bzw. von ihr wegführenden Bandleitung kann auch bei Produktbreiten, die dem Abstand der außenliegenden Bänder entsprechen, gewährleistet werden. Insgesamt kann so ein Papierstau auch dann vermieden werden, wenn bei einer bekannten Vorrichtung die nicht ablenkbaren seitlichen Produktkanten mit der Spitze der feststehenden Keilanordnung kollidieren würde.Between the baffles and the cams, the products can be guided safely and over their entire width. The products of the splitting device can be supplied safely and undamaged even at high speeds, or removed from it. Because the necessary guidance of the products at their lateral edges in the product leading to the splitting device or away from her band line can be guaranteed even with product widths that correspond to the distance of the outer bands. Overall, such a paper jam can be avoided even if, in a known device, the non-deflectable lateral product edges would collide with the tip of the fixed wedge assembly.
Zwischen den Nocken der rotierenden Nockenwalzen und den Produkten ergibt sich dabei in vorteilhafter Weise keine Relativbewegung, so dass Markierungen unterbleiben und ein Abschmieren von Farbe etc. vermieden wird.There is advantageously no relative movement between the cams of the rotating cam rollers and the products, so that markings are avoided and smearing of paint etc. is avoided.
Vorteilhaft weisen die Nockenwalzen über ihrer Länge eine Vielzahl von mit engem Abstand nebeneinander angeordneter Nocken und die Leitbleche eine Vielzahl von den Nocken zugeordneten Schlitzen auf, z.B. über 10 bis 20 oder mehr Nocken und Schlitze. Dazu können die Nockenwalzen vorteilhaft jeweils durchgehende Wellen aufweisen, auf die jeweils mehrere, mit einer Anzahl von Nocken versehene Nockenträger aufgeklemmt sind. Besonders vorteilhaft ist es dabei, wenn die Keilanordnung eine zumindest über die mit Nocken versehene Breite der Nockenwalzen durchgehende Anzahl Keile umfasst. Die in engem Abstand vielzähligen dünnen Nocken lenken das Produkt über die ganze Produktbreite sicher über den Keil bzw. die Keilanordnung in die jeweilige weiterführende Bandleitung ab. Die Keilanordnung und die Leitbleche, durch die die Nockenscheiben hindurchtauchen, begrenzen den freien Raum der Produkte und verhindern ein Umschlagen und Beschädigen der Produkte.Advantageously, the cam rollers have, over their length, a plurality of closely spaced cams and the baffles have a plurality of slots associated with the cams, e.g. over 10 to 20 or more cams and slots. For this purpose, the cam rollers can advantageously each have continuous shafts, on each of which a plurality of cams provided with a number of cams are clamped. It is particularly advantageous in this case if the wedge arrangement comprises a number of wedges extending at least over the width of the cam rollers provided with cams. The closely spaced thin cams guide the product safely over the entire width of the product over the wedge or the wedge arrangement into the respective continuous strip line. The wedge arrangement and the baffles through which the cams penetrate limit the free space of the products and prevent folding and damaging of the products.
Dabei kann die Keilanordnung einen oder mehrere Keile umfassen. Der oder die Keile können dabei entweder mit ihrer Keilspitze hinter dem von den beiden Nockenwalzen abgestrichenen Bereich liegen. In diesem Fall sorgen die die engen Abstände der Splittingnocken dafür, dass weder Produktvorderkante noch Produktende mit der festen Keilspitze in Berührung kommen kann. Die Keilspitze kann aber auch zu den Nockenwalzen hin wie die Leitbleche geschlitzt sein, so dass der oder die Keile ebenfalls von den Nocken der Nockenwalzen durchgriffen werden können und mit ihren Seitenwänden eine zusätzliche Abstützung der Produkte nach innen hin bieten.In this case, the wedge arrangement may comprise one or more wedges. The wedge or wedges can lie either with their wedge tip behind the painted off by the two cam rollers area. In this case, the close spacing of the split cams ensures that neither the product leading edge nor the product end can come into contact with the fixed wedge tip. But the wedge tip can also be slotted to the cam rollers as the baffles, so that the one or more wedges can also be penetrated by the cams of the cam rollers and offer with their side walls an additional support of the products inwards.
Wenn sich die Nocken beider Nockenwalzen jeweils über ein solches, bevorzugt gleich großes Umfangssegment erstrecken, welches bei angepasster Umfangsgeschwindigkeit jeweils eine komplette Produktlänge abstreicht, wird die Produktvorderkante , nachdem sie die Bandleitung verlassen hat von den Nocken in die entsprechende Richtung der weiterführenden Bandleitung abgelenkt und zugeführt, wobei beim Wiedereintritt der Produktvorderkante in die der Splittingvorrichtung nachgeordnete Bandleitung das Produktende noch in der der Splittingvorrichtung vorgeordneten Bandleitung geführt ist. Damit ist eine kontinuierliche Produktführung gewährleistet.If the cams of both cam rollers respectively extend over such a circumference segment, which is preferably of the same size, which in each case sweeps off a complete product length with an adapted peripheral speed, the leading edge of the product becomes After it has left the tape line has deflected and fed from the cams in the corresponding direction of the continuing strip line, wherein the reinsertion of the product leading edge in the splitting device downstream strip line the product end is still performed in the Splittingvorrichtung upstream tape line. This ensures continuous product management.
Die Bandleitung muss somit nicht durch die Vorrichtung geführt werden, sondern verläuft außerhalb um die Vorrichtung herum und nimmt anschließend die Produktführung wieder auf, so dass eine gute Führung in dem durch die Leitbleche, Nocken und optional den Keilseitenwänden gebildeten Weg gewährleistet ist, ohne dass die weiter oben beschriebene Gefahr von Papierstau entsteht.Thus, the stripline does not need to be passed through the device, but extends outside the device and then resumes product guidance so as to provide good guidance in the path formed by the baffles, cams, and optionally the wedge sidewalls, without the needles described above danger of paper jam arises.

Die Schaufelräder 15 werden von Auslegebändern 16 unterfasst, auf denen die Produkte jeweils in Form eines Schuppenstroms abgelegt werden.The longitudinally folded material, which is referred to below as strands 1a and 2a, is then subdivided into arcuate products by means of a
Die oben genannten Aggregate von den Zugeinrichtungen 5, 6 stromabwärts sind in einem Maschinengestell 17 angeordnet, in das die von den Falztrichtern 3, 4 ablaufenden Stränge 1a, 2a einlaufen. Das Maschinengestell 17 besitzt zwei Seitenwände, auf denen die genannten Einrichtungen gelagert sind. Auf das Maschinengestell 17 ist eine Aufbauwand 18 aufgesetzt, die den Falztrichtern 3, 4 zugeordnete Bahnzeitorgane 19 wie Leit- und/oder Wendestangen etc. trägt. Diese sind fliegend angeordnet und dementsprechend von ihrem von der Aufbauwand 18 abgewandten Ende her zugänglich. Der vom unteren Falztrichter 3 ablaufende Strang 1 a läuft ohne Umlenkung nach unten ab. Der vom oberen Falztrichter 4 ablaufende Strang 2a, der in der Praxis als sog. Ballonstrang bezeichnet wird, ist zur Umfahrung des unteren Falztrichters 1 seitlich ausgelenkt. Hierzu muss der Strang 2a durch die Aufbauwand 18 durchgeführt werden, die hierzu mit einem Durchführfenster 20 versehen ist.The above-mentioned units of the drawbars 5, 6 downstream are arranged in a machine frame 17, in which the running of the formers 3, 4 strands 1a, 2a enter. The machine frame 17 has two side walls on which said devices are mounted. On the machine frame 17, a mounting wall 18 is placed, which the folding hoppers 3, 4 associated Bahnzeitorgane 19 such as guide and / or turning bars etc. carries. These are arranged in a flying position and accordingly accessible from their end remote from the mounting wall 18. The running from the lower former 3 strand 1 a runs without deflection down. The running of the upper former 4 strand 2a, which is referred to in practice as so-called. Balloon strand, is deflected laterally for bypassing the lower Former 1. For this purpose, the strand 2a must be performed by the building wall 18, which is provided for this purpose with a feed-through
Die Aufbauwand 18 ist so angeordnet, dass die fliegend angeordneten Leitorgane 19 von der Seite der durch einen Pfeil 21 angedeuteten Bahnzuführung her gut zugänglich sind. Die Aufbauwand 18 ist dabei gegenüber einer Mittelebene der Falztrichteranordnung seitlich versetzt. Die Richtung der Bahnzuführung hängt von der Anordnung vorgeordneter Einrichtungen ab und kann sich daher ändern. Wenn die Bahnzuführung von der dem Pfeil 21 entgegengesetzten Seite her erfolgt, muss die Aufbauwand 18 auf der anderen Seite der Falztrichteranordnung angeordnet werden, wie in
Um Variationen oben genannter Art zu vereinfachen besteht das Maschinengestell 17 aus mehreren, aufeinander angeordneten Moduln, die um 180° gegeneinander verdrehbar und in den jeweiligen Endstellungen aneinander festlegbar sind. Zwei Moduln sind praktisch ausreichend. Dementsprechend sind im dargestellten Beispiel zwei Moduln, nämlich ein oberes Modul 22 und ein unteres Modul 23 vorgesehen. Das obere Modul 22 enthält die Zugeinrichtungen 6, 7 mit zugeordneten Leit- und Umlenkrollen 7,8, die Querschneideinrichtung 9 und die Splittingeinrichtung 10. Das untere Modul 23 enthält die an die Splittingeinrichtung 10 anschließenden Bandleitungen 11,12 sowie die diesen zugeordneten Bremseinrichtungen 14, Schaufelräder 15 und Auslagebänder 16. Im Bereich der rechtwinklig zur vertikalen Drehachse verlaufenden Teilfuge 24 zwischen den gegeneinander verdrehbaren Moduln 22 und 23 haben diese gegenseitige Anlageflächen sowie zu einer die Drehachse enthaltenden, vertikalen Arbeitsebene eines benachbarten Aggragats symmetrisch angeordnete, hier durch ihre Mittellinien angedeutete Befestigungsmittel 25 zu ihrer gegenseitigen Verankerung im aufeinander aufgesetzten Zustand in jeder gewünschten Drehendstellung.In order to simplify variations of the type mentioned above, the machine frame 17 consists of a plurality of mutually arranged modules which are rotatable by 180 ° from each other and in the respective end positions are fixed to each other. Two modules are practically sufficient. Accordingly, in the illustrated example, two modules, namely an
Um in jeder Drehendstellung die Produkte in gleicher Weise über die Teilfuge 24 hinweg leiten zu können, sind die im Bereich der Teilfuge 24 vorgesehenen Aggregate symmetrisch zu ihrer die Drehachse enthaltenden, vertikalen Arbeitsebene und dementsprechend zu ihrer vertikalen Mittelebene ausgebildet. Die die Drehachse enthaltende vertikale Arbeitsebene entspricht einer vertikalen Mittelebene, d.h. der Transportebene der Produkte beim Durchgang durch die Teilfuge 24. Diese Symmetrie gilt im dargestellten Ausführungsbeispiel für den Ausgang der Splittingeinrichtung 10 und den Eingang der hieran anschließenden Bandleitungen 11, 12.In order to be able to guide the products in the same way over the parting
Um die Drehbarkeit der Moduln 22 bzw. 23 zu erleichtern, ist jedes Modul antriebsmäßig autark ausgebildet. Hierzu ist jedem Modul wenigstens ein moduleigener Antriebsmotor zugeordnet. Im dargestellten Beispiel sind zweckmäßig auf jedem Modul mehrere Antriebsmotoren vorgesehen. So ist jeder Zugeinrichtung 5, 6 ein eigener Antriebsmotor 26, 27 zugeordnet. Der Querschneideinrichtung 9 ist ein eigener Antriebsmotor 28 und der Splittingeinrichtung 10 ein eigener Antriebsmotor 29 zugeordnet. Dementsprechend enthält das obere Modul 22 die vier voneinander unabhängigen Antriebsmotoren 26 - 29. Den Bremseinrichtungen 14, Schaufelrädern 15 und Auslegebändern 16 des unteren Moduls sind ebenfalls jeweils eigene Antriebsmotoren 30, 31 bzw. 32, 33 bzw. 34, 35 zugeordnet. Das untere Modul 22 enthält dementsprechend sechs voneinander unabhängige Antriebsmotoren 30 - 35. Die gegenseitige Unabhängigkeit der Antriebsmotoren 26 - 35 erleichtert die Steuerung sowie die Bewerkstelligung jeder gewünschten Vor- bzw. Nacheilung, was sich vorteilhaft auf die Genauigkeit und schonende Betriebsweise auswirkt.In order to facilitate the rotation of the
Die Bandleitungen 11, 12 durchqueren im dargestellten Beispiel die Teilfuge 24. Die Bänder der Bandleitungen 11, 12 müssen daher abgenommen werden, bevor eines der Moduln 22, 23 verdreht wird. Die im Bereich der Teilfuge 24 vorgesehenen inneren Bandrollen 36 der Bandleitungen 11, 12 sind jedoch symmetrisch zu der oben genannten Arbeitsebene angeordnet, so dass sich nach der Drehung eines der Moduln 22, 23 dort derselbe Bänderverlauf ergibt, wie vor der Drehung.The strip lines 11, 12 traverse the
Die von den Falztrichtern 3, 4 ablaufenden Stränge 1a, 2a können nach der Vereinigung je nach Trichteranordnung aufeinander liegend oder nebeneinander liegend weiter transportiert werden. Um jede Möglichkeit offen zu halten und eine hohe Flexibilität zu gewährleisten, sind alle Organe und Einrichtungen von der Vereinigungsstelle 37 an stromabwärts zweispurig ausgebildet, d.h. so, dass bei Bedarf zwei Stränge nebeneinander laufen können. Die Seitenwände der Gestelle der Moduln 22, 23 sind dabei entsprechend weit voneinander entfernt, so dass sich die erforderliche Arbeitsbreite ergibt. Diese hier erwähnte Zweispurigkeit liegt den Einrichtungen gemäß
Die in
Die Länge der Produkte ist abhängig vom Durchmesser der Schneidwalzen 38. Im Falle einer Änderung der Länge müssen die Schneidzylinder 38 ausgetauscht werden. Um dies zu vereinfachen, sind die Schneidzylinder 38 in seitlichen Exzenterlagen 41 gelagert. Durch Drehen der Exzenterlalger 41 kann daher der Achsabstand verändert werden.The length of the products is dependent on the diameter of the cutting

Die Welle 57 dreht sich in jedem Fall auf ihrer ganzen Länge. Die den beiden Spuren zugeordneten Bänder 58 sind jedoch spurweise aktivierbar bzw. passivierbar. Hierzu können die zugeordneten Bandrollen bzw. Bandtrommeln 59 mittels einer Kupplung 62 wahlweise mit der Welle 57 gekuppelt werden. Von der antriebsmäßig mit der Querschneideinrichtung 9 verbundenen Welle 57 der ersten Bandwalze 55 kann der Antrieb auf weitere, angetriebene Bandwalzen weitergeleitet werden. Hierzu ist auf einem Ende der Welle 57 eine zweite Riemenscheibe 63 vorgesehen, von der ein Treibriemen 64 zu einer entsprechenden Riemenscheibe einer weiteren Bandwalze führt.The shaft 57 rotates in any case along its entire length. However, the bands 58 assigned to the two tracks can be activated or passivated on a track-by-track basis. For this purpose, the associated tape reels or tape reels 59 can be selectively coupled to the shaft 57 by means of a coupling 62. Of the drivingly connected to the

Gemäß dem oben beschriebenen Beispiel enthält das Maschinengestell 17 nur das obere Modul 22 und das untere Modul 23, also nur zwei Moduln. Es wäre jedoch auch denkbar, mehrere Moduln vorzusehen. Hierzu könnte z.B. das obere Modul 22 der Anordnung gemäß
Vorstehend ist zwar ein bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert, ohne dass jedoch hiermit eine Beschränkung sein soll. Vielmehr stehen dem Fachmann eine Reihe von Möglichkeiten zur Verfügung, um die allgemeine Idee an die Verhältnisse des Einzelfalls anzupassen.Although a preferred embodiment of the invention is explained in more detail above, without, however, is intended to be a limitation. Instead, a number of options are available to the person skilled in the art in order to adapt the general idea to the circumstances of the individual case.
