Die Erfindung betrifft ein Verfahren zur Herstellung einer Einrichtung zum Aufbewahren von Feststoffen, Flüssigkeiten und/oder Gasen, insbesondere eines Behälters zum Aufbewahren von Lebensmitteln, gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zum Ausführen des erfindungsgemäßen Herstellverfahrens.The invention relates to a method for producing a device for storing solids, liquids and / or gases, in particular a container for storing food, according to the preamble of claim 1 and a device for carrying out the manufacturing method according to the invention.
Ein Verfahren zur Herstellung eines Futtersilos ist aus der DE-OS 1 936 021 bekannt. Dabei wird ein Band von einer Vorratsrolle entnommen und wendelartig unter Bildung einer Schraubenlinie zu einer Mantelfläche der Einrichtung verformt. Die Längsränder des Bandes werden entlang einer Biegelinie unter Bildung einer Kante nach außerhalb des Silos abgebogen und die benachbarten Längsränder werden mittels eines Falzes oder Doppelfalzes miteinander verbunden. Die Herstellung des Falzes zum Verbinden der Längsränder ist beispielsweise aus der DE-PS 27 22 227 bekannt. Der Falz steht dabei auf der Außenseite des im wesentlichen zylindrischen Silos ab.A method for producing a feed silo is known from DE-OS 1 936 021. Here, a tape is removed from a supply roll and helically deformed to form a helical line to form an outer surface of the device. The longitudinal edges of the belt are bent along a bending line to form an edge outside the silo and the adjacent longitudinal edges are connected to one another by means of a fold or double fold. The production of the fold for connecting the longitudinal edges is for example from DE-PS 27 22 227 known. The fold protrudes from the outside of the essentially cylindrical silo.
Eine zugehörige Vorrichtung zum Ausführen des Herstellverfahrens umfaßt eine außerhalb des herzustellenden Silos angeordnete Verbindungsstation zum Verbinden der Längsränder, wie sie beispielsweise aus der DE-PS 22 10 055 bekannt ist. Nach dem erfindungsgemäßen Verfahren bzw. mit der erfindungsgemäßen Vorrichtung herstellbare Einrichtungen für ein bestimmtes Einsatzgebiet sind u. a. hinsichtlich ihrer Abmessungen und Werkstoffe aus der Produktinformation „Flüssigkeitsbehälter für Wasser, Abwasser, Klärschlamm ..." der Lipp GmbH Maschinen- und Stahl behälterbau Umwelttechnik, und aus der Produktinformation „Flüssigdungbehälter" der Lipp GmbH Stahlsilobau, jeweils in D-73497 Tannhausen, bekannt.An associated device for executing the manufacturing process comprises a connection station arranged outside the silo to be manufactured for connecting the longitudinal edges, as is known for example from DE-PS 22 10 055. According to the method according to the invention or with the device according to the invention producible devices for a certain area of application are u. a. with regard to their dimensions and materials from the product information "Liquid container for water, sewage, sewage sludge ..." from Lipp GmbH Maschinen- und Stahlbehälderbau Umwelttechnik, and from the product information "Liquid manure container" from Lipp GmbH Stahlsilobau, each in D-73497 Tannhausen .
Bei bestimmten Einsatzgebieten ist es erforderlich, daß die Fuge an den miteinander verbundenen Längsrändern auf der Innenseite des Behälters keine Hohlstellen oder Ritze aufweist bzw. daß die Fuge mitteis eines Dichtmittels verschlossen ist. Hierzu kann beispielsweise ein Strang Silicon in den Falz eingelegt werden, der beim Verpressen der Ränder aus demIn certain areas of application, it is necessary that the joint at the interconnected longitudinal edges on the inside of the container has no cavities or cracks or that the joint is closed by means of a sealant. For this purpose, for example, a strand of silicone can be inserted into the fold, which is removed from the edge when the edges are pressed
Falz herausquillt und die Fuge verschließt. Dieses Verfahren ist aufwendig, insbesondere wenn ein Überstand des Dichtmaterials auf der Behälterinnenseite aus beispielsweise hygienischen Gründen zu vermeiden ist. Darüber hinaus sind die verwendeten Dichtstoffe aufgrund ihrer Löslichkeit und nicht ausreichenden Langzeitstabilität für einige Einsatzgebiete, beispielsweise für die Lagerung von Lebensmitteln, ungeeignet. Der Erfindung liegt daher das Problem zugrunde, ein Verfahren und eine zugehörige Vorrichtung zur Herstellung einer Einrichtung zum Aufbewahren von Feststoffen, Flüssigkeiten oder Gasen bereitzustellen, welche die Nachteile des Standes der Technik überwinden. Insbesondere soll das Verfahren hohen Anforderungen an die Dichtheit, Langzeitstabilität und Hygiene genügen und kostengünstig ausführbar sein.Fold swells out and the joint closes. This method is complex, in particular if a protrusion of the sealing material on the inside of the container is to be avoided, for example for hygienic reasons. In addition, due to their solubility and insufficient long-term stability, the sealants used are unsuitable for some areas of application, for example for the storage of food. The invention is therefore based on the problem of providing a method and an associated device for producing a device for storing solids, liquids or gases which overcome the disadvantages of the prior art. In particular, the method should meet high requirements for tightness, long-term stability and hygiene and should be inexpensive to carry out.
Das Problem wird durch das im Anspruch 1 bestimmte Verfahren und die im Anspruch 10 bestimmte Vorrichtung gelöst. Besondere Ausführungsarten der Erfindung sind in den Unteransprüchen bestimmt.The problem is solved by the method defined in claim 1 and the device defined in claim 10. Particular embodiments of the invention are defined in the subclaims.
Dadurch, daß vor dem Abbiegen zum Bilden der Kante in das Band entlang der Biegelinie eine Ausnehmung, beispielsweise in Form einer Rinne, Nut oder Sicke, eingebracht wird, läßt sich der Längsrand des Bandes mit einem kleineren Radius abbiegen, der eine ausreichend schmale Fuge zwischen benachbarten Längsrändern ergibt. Vorzugsweise erfolgt das Einbringen der Ausnehmung unmittelbar vor dem Abbiegen des Bandes und/oder unter kontinuierlichem Materialfluß, beispielsweise dem Abrollen des Bandes von einer Vorratsrolle. Die Ausnehmung wird vorzugsweise auf der Fläche des Bandes eingebracht, die sich beim Biegen aufeinander zubewegt.Characterized in that a recess, for example in the form of a groove, groove or bead, is made before bending to form the edge in the band along the bending line, the longitudinal edge of the band can bend with a smaller radius that a sufficiently narrow joint between adjacent longitudinal edges. The recess is preferably made immediately before the band is bent and / or under a continuous flow of material, for example the band unrolling from a supply roll. The recess is preferably made on the surface of the band which moves towards one another during bending.
Atlernativ oder ergänzend kann die Ausnehmung auch auf der Fläche des Bandes eingebracht werden, die beim Abbiegen bzw. Abkanten gestreckt wird. In der Regel wird die Ausnehmung auf der die Behälteraußenseite bildenden Fläche des Bandes eingebracht. Das Band ist vorzugsweise ein metallisches Blech, insbesondere aus Aluminium, verzinktem Stahl oder aus Edelstahl, das kunststoffbeschichtet sein kann. Möglich ist auch eine Werkstoff-Kombination von verzinktem Stahl auf der Behälteraußenseite und Edelstahl auf der Behälterinnenseite. Typische Blechdicken betragen zwischen 1 und 10 mm, insbesondere zwischen 2 und 4 mm, abhängig von der Belastung des herzustellenden Behälters.Atlaterally or in addition, the recess can also be made on the surface of the band that is stretched when bending or folding. As a rule, the recess is made on the surface of the belt forming the outside of the container. The band is preferably a metallic sheet, in particular made of aluminum, galvanized steel or stainless steel, which can be plastic-coated. A combination of materials is also possible: galvanized steel on the outside of the container and stainless steel on the inside of the container. Typical sheet thicknesses are between 1 and 10 mm, in particular between 2 and 4 mm, depending on the load on the container to be manufactured.
Die Längsränder werden vorzugsweise nach außerhalb des Behälters abgebogen und dort derart miteinander verbunden und gegebenenfalls abgewinkelt, daß kein Regenwasser in die Verbindungsstelle eindringen kann. Das Verbinden kann beispielsweise durch Falzen, Schweißen, Schrauben und/oder Nieten erfolgen. Vorzugsweise werden die Behälter direkt am Aufstellort hergestellt, wobei sowohl die Vorratsrolle, beispielsweise eine Haspel oder ein Coil, als auch die Biege- undThe longitudinal edges are preferably bent outside of the container and connected there with one another and, if necessary, angled so that rainwater cannot penetrate into the connection point. The connection can take place, for example, by folding, welding, screwing and / or riveting. The containers are preferably produced directly at the installation location, with both the supply roll, for example a reel or a coil, and the bending and
Verbindungsstation auf dem Boden stehen und der Behälter beginnend mit der obersten Windung des Bandes schraubenförmig drehend von unten in die Höhe anhebend hergestellt wird. Parallel zur Behälterherstellung kann eine Außenlackierung erfolgen. Auf diese Weise sind Behälter für beliebige Medien herstellbar, beispielsweise Silos für Getreide, Wasserbehälter oder Biogasreaktoren.Stand the connection station on the floor and the container is made starting with the topmost turn of the belt, rotating in a helical manner and lifting from below. External painting can be carried out in parallel with the production of the container. In this way, containers for any media can be produced, for example silos for grain, water containers or biogas reactors.
Dadurch, daß die Ausnehmung spanlos eingeformt wird, insbesondere eingepreßt wird, ist die Festigkeit der Biegestelle erhöht. Mit einer entsprechenden Formwalze können nahezu beliebige Querschnittsformen der Ausnehmung hergestellt werden. Alternativ ist auch ein spanendes Einformen möglich, beispielsweise durch Fräsen oder Stoßen.The fact that the recess is formed without cutting, in particular is pressed in, increases the strength of the bending point. Almost any cross-sectional shape of the recess can be produced with a corresponding shaping roller. Alternatively, machining is also possible, for example by milling or shaping.
Dadurch, daß die Ausnehmung so ausgestaltet ist, daß der Biegeradius der Kante kleiner als die zweifache Banddicke ist und/oder daß die Ausnehmung mit einer Tiefe von 10 bis 50 % der Banddicke, insbesondere 25 bis 35 %, eingebracht wird, lassen sich bei hoher Festigkeit sehr kleine Fugen zwischen den Längsrändern erzielen, beispielsweise Fugen mit einer Breite, die der zwei- bis fünffachen Banddicke entspricht.The fact that the recess is designed such that the bending radius of the edge is less than twice the strip thickness and / or that the recess is made with a depth of 10 to 50% of the strip thickness, in particular 25 to 35%, can be made larger Achieve very small joints between the longitudinal edges, for example joints with a width that corresponds to two to five times the strip thickness.
Dadurch, daß die benachbarten Längsränder einen Falz bilden und insbesondere in den Falz vor dem Zusammenpressen eine verformbare und abdichtende Masse, beispielsweise aus Silicon, eingelegt wird, ist die Dichtwirkung erhöht.The fact that the adjacent longitudinal edges form a fold and in particular a deformable and sealing compound, for example made of silicone, is inserted into the fold before being pressed together, the sealing effect is increased.
Alternativ oder ergänzend zum Einbringen einer abdichtenden Masse und/oder zur Bildung eines Falzes können die Längsränder vorzugsweise auf der Innenseite der Einrichtung im Bereich der sich bildenden Fuge miteinander verschweißt werden. Dadurch ist eine dauerhaft dichte Verbindung gewährleistet, die höchsten Anforderungen genügt. Soweit dies wünschenswert und/oder erforderlich ist, kann die entstehende Schweißnaht auf der Innenseite der Einrichtung planarisiert werden.As an alternative or in addition to the introduction of a sealing compound and / or the formation of a fold, the longitudinal edges can preferably be welded to one another on the inside of the device in the region of the joint that forms. This ensures a permanently tight connection that meets the highest requirements. Insofar as this is desirable and / or necessary, the weld seam that is created can be planarized on the inside of the device.
Dadurch ist auf der Innenseite des Behälters ein nahtloser und ritzenfreier Übergang zwischen den miteinander verbundenen Längsrändern des Bandes erzielbar.As a result, a seamless and crack-free transition between the interconnected longitudinal edges of the belt can be achieved on the inside of the container.
Die erfindungsgemäße Vorrichtung zum Ausführen des Herstellverfahrens umfaßt eine Biegestation und eine nachfolgende Verbindungsstation. Die Biegestation umfaßt vor einem Biegewerkzeug zum Bilden der Kante ein Bearbeitungswerkzeug, mittels dem entlang der Biegelinie die Ausnehmung in das Band einbringbar ist. Da das Eindringen der Ausnehmung unmittelbar vor dem Abbiegen der Kante erfolgt, sind die Abmessungen und die Form der Ausnehmung unmittelbar am Herstellort auf den jeweiligen Anwendungsfall einstellbar. Außerdem kann handelsübliches Bandmaterial, insbesondere Stahlbandmaterial, verwendet werden. Dadurch, daß das Bearbeitungswerkzeug eine Formwalze ist, mittels der die Ausnehmung spanlos in das Band einpreßbar ist, können nahezu beliebige Formen und Abmessungen der Ausnehmung kostengünstig hergestellt werden. Vorzugsweise ist die Formwalze so ausgestaltet, daß die Ausnehmung im Querschnitt teilkreisförmig, teilelliptisch oder dreieckig ist.The device according to the invention for carrying out the manufacturing process comprises a bending station and a subsequent connecting station. In front of a bending tool for forming the edge, the bending station comprises a processing tool, by means of which the recess can be made in the band along the bending line. Since the recess penetrates immediately before the edge is bent, the dimensions and the shape of the recess can be adjusted to the respective application directly at the place of manufacture. Commercial strip material, in particular steel strip material, can also be used. The fact that the machining tool is a form roller, by means of which the recess can be pressed into the strip without cutting, almost any shape and size of the recess can be produced inexpensively. The shaping roller is preferably designed in such a way that the recess is partially circular, partially elliptical or triangular in cross section.
Dadurch, daß die Verbindungsstation ein Schweißgerät umfaßt, mittels der die benachbarten Längsränder auf der Innenseite der Einrichtung im Bereich der sich bildenden Fuge verschweißbar sind, ist eine dauerhaft feste Verbindung gewährleistet. Das Verschweißen kann zusätzlich oder alternativ zu einem weiteren Verbindungsverfahren, beispielsweise dem Falzen der Längsränder, erfolgen.The fact that the connection station comprises a welding device, by means of which the adjacent longitudinal edges can be welded on the inside of the device in the region of the joint that is formed, ensures a permanently firm connection. The welding can take place in addition or as an alternative to a further connection method, for example the folding of the longitudinal edges.
Dadurch, daß die Verbindungsstation dem Schweißgerät nachgeordnet ein Planarisierungsgerät zum Planarisieren der Schweißnaht umfaßt, sind besonders glatte Innenoberflächen des herzustellenden Behälters erreichbar. Dies ist insbesondere dann von Vorteil, wenn das Schweißen keine hohlkehlenförmige, sondern eine buckeiförmige Schweißnaht ergibt.Due to the fact that the connection station includes a planarization device for planarizing the weld seam downstream of the welding device, particularly smooth inner surfaces of the container to be produced can be achieved. This is particularly advantageous if the welding does not result in a fillet-shaped but a hump-shaped weld.
Dadurch, daß die Biegestation und die Vorratsrolle innerhalb der herzustellenden Einrichtung angeordnet sind, und die Verbindungsstation teilweise innerhalb und teilweise außerhalb der herzustellenden Einrichtung angeordnet sind, ist die Vorrichtung modular am Herstellort aufbaubar. Die Anordnung und gegenseitige Winkelausrichtung der Bearbeitungsgeräte innerhalb der Biege- und Verbindungsstation sind dabei entsprechend den Abmessungen des herzustellenden Behälters einstellbar. Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus den Unteransprüchen sowie der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel im einzelnen beschrieben ist. Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Due to the fact that the bending station and the supply roll are arranged inside the device to be produced, and the connecting station is partly arranged inside and partly outside of the device to be produced, the device can be constructed modularly at the place of manufacture. The arrangement and mutual angular alignment of the processing devices within the bending and connecting station can be adjusted according to the dimensions of the container to be manufactured. Further advantages, features and details of the invention emerge from the subclaims and the following description, in which an exemplary embodiment is described in detail with reference to the drawings. The features mentioned in the claims and in the description can each be essential to the invention individually or in any combination.

Die Fig. 1 zeigt eine mit dem erfindungsgemäßen Verfahren herstellbare Einrichtung. Dabei handelt es sich um einen Aufbewahrungsbehälter 1 für flüssige Lebensmittel. Die Mantelfläche 2 ist dabei wendelartig aus streifenförmig aneinandergesetztem Bandmaterial gebildet. Auf jeder zweiten Windung sind übereinander angeordnete verschließbare Luken 4 vorgesehen. Das Fußende des im wesentlichen zylindrischen Behälters 1 ist beispielsweise in einem Betonsockel 6 eingelassen. Der Behälter 1 ist im Querschnitt vorzugsweise kreisrund. Die wendelartig verlaufenden Längsränder 24, 26 des Bandes sind unter Bildung eines nach außerhalb des Behälters abstehenden Falzes 8, der ebenfalls wendelartig verläuft, miteinander verbunden.1 shows a device which can be produced using the method according to the invention. This is a storage container 1 for liquid food. The lateral surface 2 is helically formed from strip material put together in strips. Lockable hatches 4 arranged one above the other are provided on every second turn. The foot end of the essentially cylindrical container 1 is embedded in a concrete base 6, for example. The container 1 is preferably circular in cross section. The helical longitudinal edges 24, 26 of the band are connected to one another to form a fold 8 projecting outward from the container, which also extends helically.
Die Fig. 2A bis 2C zeigen die verschiedenen Stadien beim Verformen des Bandes 10. Die Bandlängsrichtung verläuft dabei senkrecht zur Zeichenebene der Fig. 2A. In einem ersten Schritt wird in der Biegestation 38, wie in der Fig. 2B dargestellt, mittels einer Formwalze 12 unter gleichzeitiger Anlage einer Gegendruckwalze 14 auf der gegenüberliegenden Seite des Bandes 10 entlang einer senkrecht zur Zeichenebene verlaufenden Biegelinie eine Ausnehmung 16 in das Band 10 eingebracht. Entsprechende Ausnehmungen 16' werden mittels weiterer Form- und Gegendruckwalzen 12', 14' überall dort in das Band 10 eingebracht, wo abgekantete Längsränder 24, 26 mit benachbarten Längsrändern eine Fuge bilden. Alle Ausnehmungen 16, 16' können vorzugsweise mit einer einzigen Form- bzw. Gegendruckwalze hergestellt werden. Alternativ können die Ausnehmungen 16, 16' gleichzeitig oder nacheinander mit individuellen Form- bzw. Gegendruckwalzen 12, 14; 12', 14' hergestellt werden. Die Ausnehmungen 16, 16' werden vorzugsweise auf der die Außenseite bildenden Fläche der herzustellenden Einrichtung und auf der Fläche 18 eingebracht, die sich beim Abbiegen der Längsränder 24, 26 aufeinander zubewegt. Die Tiefe 20 der eingebrachten Ausnehmungen 16, 1 6' beträgt ca. ein Drittel der Banddicke 22. Die Ausnehmung 16 ist im dargestellten Querschnitt im wesentlichen teilkreisförmig. Die Breite der Ausnehmung 16 auf der Fläche 18 beträgt das Zwei- bis Vierfache der Banddicke 22.2A to 2C show the various stages in the deformation of the strip 10. The longitudinal direction of the strip is perpendicular to the Drawing plane of Fig. 2A. In a first step, a recess 16 is made in the band 10 in the bending station 38, as shown in FIG . Corresponding recesses 16 'are made by means of further shaping and counter-pressure rollers 12', 14 'in the strip 10 wherever folded longitudinal edges 24, 26 form a joint with adjacent longitudinal edges. All recesses 16, 16 'can preferably be produced with a single shaping or counter-pressure roller. Alternatively, the recesses 16, 16 'can be carried out simultaneously or successively with individual shaping or counter-pressure rollers 12, 14; 12 ', 14' can be produced. The recesses 16, 16 'are preferably introduced on the surface of the device to be manufactured which forms the outside and on the surface 18 which moves towards one another when the longitudinal edges 24, 26 are bent. The depth 20 of the recesses 16, 16 ′ introduced is approximately one third of the strip thickness 22. The recess 16 is essentially part-circular in the cross section shown. The width of the recess 16 on the surface 18 is two to four times the strip thickness 22.
Die Fig. 2C zeigt entsprechend dem den Behälter 1 von unten nach oben aufbauenden Herstellverfahren zwei unterschiedliche Stadien bei der Verbindung der Längsränder 24, 26 des Bandes 10. In der unteren Bildhälfte der Fig. 2C ist die Verformung der benachbarten Längsränder 24, 26 unter Bildung eines Falzes dargestellt. Die Verformung der Längsränder 24, 26 erfolgt unter Verwendung entsprechender (nicht dargestellter) Formwalzen. Der Biegeradius 28 entspricht im dargestellten Ausführungsbeispiel etwa dem 1 ,5-fachen der Banddicke 22. Die sich an der Stoßstelle der Längsränder 24, 26 ergebende Fuge 30 hat eine Breite, die etwa der zweifachen Banddicke 22 entspricht. In der oberen Bildhälfte der Fig. 2C sind die Längsränder 24, 26 unter Bildung des Falzes 8 vollständig miteinander verpreßt. Zusätzlich sind die beiden Längsränder 24, 26 im Bereich der Fuge 30 miteinander verschweißt. Die Schweißnaht 32 bildet auf der inneren Oberfläche 34 des hergestellten Behälters 1 beispielsweise eine Hohlkehle mit großem Radius aus und dichtet den Falz 8 zuverlässig und dauerhaft nach innen ab. Alternativ zur hohlkehlförmigen Schweißnaht 32 kann auch eine buckeiförmige Schweißnaht vorgesehen werden, die dann vorzugsweise in einem anschließenden2C shows two different stages in the connection of the longitudinal edges 24, 26 of the band 10 in accordance with the manufacturing process which builds the container 1 from bottom to top. In the lower half of FIG. 2C, the deformation of the adjacent longitudinal edges 24, 26 is formed of a fold. The longitudinal edges 24, 26 are deformed using appropriate shaping rollers (not shown). In the exemplary embodiment shown, the bending radius 28 corresponds approximately to 1.5 times the strip thickness 22 The joint 30 resulting in the joint of the longitudinal edges 24, 26 has a width which corresponds approximately to twice the strip thickness 22. In the upper half of FIG. 2C, the longitudinal edges 24, 26 are completely pressed together to form the fold 8. In addition, the two longitudinal edges 24, 26 are welded together in the region of the joint 30. The weld seam 32 forms, for example, a fillet with a large radius on the inner surface 34 of the manufactured container 1 and reliably and permanently seals the fold 8 inwards. As an alternative to the fillet-shaped weld seam 32, a hump-shaped weld seam can also be provided, which is then preferably in a subsequent one
Planarisierungsschritt plan mit der inneren Oberfläche 34 des Behälters 1 gemacht wird, beispielsweise durch Abschleifen.Planarization step is made flat with the inner surface 34 of the container 1, for example by grinding.
Die Fig. 3 zeigt die Aufsicht auf den Behälter 1 und die schematisch dargestellte Herstellvorrichtung. Das Band 10 wird von einer Vorratsrolle 36 entnommen und einer innerhalb des herzustellenden Behälters 1 angeordneten Biegestation 38 zugeführt. Vor den Walzenpaaren 42a, 42b ist die Formwalze 12 und Gegendruckwalze 14 angeordnet, um die Ausnehmung 16 in das Band 10 einzubringen. Die Walzenpaare 12, 14; 42a; 42b sind über Scharniere 44 in ihrer Winkelausrichtung zueinander einstellbar, zur Anpassung an den Durchmesser des herzustellenden Behälters 1 . Nachdem das Band 10 an seinen Längsrändern 24, 26 entsprechend abgebogen ist, wird es der Verbindungsstation 46 zugeführt. Dort werden mittels der Walzenpaare 48a, 48b die Längsränder 24, 26 zum Falz 8 verpreßt. Mit dem nachgeordneten Schweißgerät 50 werden die Längsränder im Bereich der Fuge 30 miteinander verschweißt. Das optional nachfolgende Planarisierungsgerät 52 ebnet Unebenheiten im Bereich der Schweißnaht 32 ein. Auch die einzelnen Walzenpaare 48a, 48b und die Schweiß- bzw. Planarisierungsgeräte 50, 52 sind mittels Scharnieren 54 im Winkel zueinander einstellbar und damit an den Durchmesser des Behälters 1 anpaßbar.3 shows the top view of the container 1 and the schematically illustrated manufacturing device. The tape 10 is removed from a supply roll 36 and fed to a bending station 38 arranged inside the container 1 to be manufactured. The shaping roller 12 and counter-pressure roller 14 are arranged in front of the roller pairs 42a, 42b in order to introduce the recess 16 into the belt 10. The roller pairs 12, 14; 42a; 42b, their angular alignment with respect to one another can be adjusted via hinges 44, to adapt to the diameter of the container 1 to be produced. After the band 10 has been bent at its longitudinal edges 24, 26, it is fed to the connecting station 46. There the longitudinal edges 24, 26 are pressed into the fold 8 by means of the roller pairs 48a, 48b. The longitudinal edges in the area of the joint 30 are welded to one another with the downstream welding device 50. The optionally subsequent planarization device 52 levels out unevenness in the area of the weld seam 32. The individual roller pairs 48a, 48b and the welding or planarization devices 50, 52 are also means Hinges 54 can be adjusted at an angle to one another and can thus be adapted to the diameter of the container 1.
Die Fig. 4A und 4B zeigen die Ausbildung des Falzes 8 als Doppelfalz 8', bei dem der abgekantete Längsrand 26 in den ebenfalls abgekanteten4A and 4B show the formation of the fold 8 as a double fold 8 ', in which the folded longitudinal edge 26 in the also folded
Längsrand 24 eingeschlagen wird. Zusätzlich wird vor dem Verpressen des Doppelfalzes 8' eine dauerelastische abdichtende Masse 56, vorzugsweise aus einem siliconhaltigen Werkstoff, zwischen die beiden Längsränder 24, 26 eingelegt. Die abdichtende Masse 56 quillt beim Falzen der Längsränder 24, 26 in alle Ritzen und bildet an der inneren Oberfläche 34 im Bereich der Fuge 30 beispielsweise eine Hohlkehlnaht 58, die aufgrund des durch die angeformte Ausnehmung erzielbaren geringen Biegeradius 28 eine geringe Oberfläche hat und im wesentlich plan ist. Longitudinal edge 24 is turned. In addition, a permanently elastic sealing compound 56, preferably made of a silicon-containing material, is inserted between the two longitudinal edges 24, 26 before the double fold 8 'is pressed. The sealing compound 56 swells in all cracks when the longitudinal edges 24, 26 are folded and forms a fillet weld 58 on the inner surface 34 in the region of the joint 30, for example, which has a small surface area and essentially because of the small bending radius 28 that can be achieved by the integrally formed recess is plan.
