  • the filling cartridge can be made of different thickness plastic film material.
  • the film material used can have a thickness of 20 ⁇ m. Since the pressure in the cartridge is much greater with a larger compression ratio, the film material must then also be thicker.

Abstract

PCT No. PCT/EP95/04456 Sec. 371 Date Jul. 10, 1996 Sec. 102(e) Date Jul. 10, 1996 PCT Filed Nov. 13, 1995 PCT Pub. No. WO96/15065 PCT Pub. Date May 23, 1996A process is described for filling an envelope of a cushion, a quilt, or the like, which envelope is essentially closed envelope with a closable filling opening, and having a filling material of individual aggregates, e.g. fiber aggregates, down, feathers, pieces of foam material. The reversibly compressible aggregates, which are in a separate filling material cartridge that has a far smaller volume than the maximum volume of the envelope and which are thus under high pressure, are introduced into the envelope through the opening along with at least a part of the filling material cartridge, whereupon the filling material cartridge is opened inside the envelope and the envelope is filled as the aggregates expand out from the filling material cartridge. This novel filling operation can be carried out by the specialty retailer or even by the end customer without additional special filling equipment.

Beschreibungdescription
Technisches GebietTechnical field
Die Erfindung betrifft ein Verfahren zum Herstellen eines Kissens, einer Decke oder dergleichen, gemäß Oberbegriff des Anspruches 1, eine zur Ausübung des Verfahrens geeignete Füll¬ gutkartusche, ein Verfahren zur Herstellung der Füllgutkartusche und eine zur Ausübung des Verfahrens geeignete Hülle.The invention relates to a method for producing a pillow, a blanket or the like, according to the preamble of claim 1, a filling cartridge suitable for carrying out the method, a method for producing the filling cartridge and a cover suitable for carrying out the method.
Stand der TechnikState of the art
Kissen, Decken, oder dergleichen werden bisher dadurch her¬ gestellt, daß beim Produzenten oder beim Händler eine Hülle mit einer bestimmten Menge an Füllmaterial gefüllt und die Hülle daraufhin verschlossen wird, bevor der fertige Gegenstand an den Handel bzw. an den Endkunden übergeben wird. Zumindest der End¬ kunde erhält immer einen fertig gefüllten Gegenstand, wie ein Kissen, z.B. Kopfkissen, eine Decke, wie z.B. eine Bettdecke oder dergleichen. Die im wesentlichen geschlossenen Hüllen wei¬ sen dabei schon öfter eine offen- und wieder verschließbare Einfüllöffnung auf.Cushions, blankets, or the like have hitherto been produced by filling a cover with a certain amount of filling material at the producer or dealer and then closing the cover before the finished article is handed over to the retailer or to the end customer. At least the end customer always receives a completely filled object, such as a pillow, e.g. Pillows, a blanket, e.g. a duvet or the like. The essentially closed casings often have an opening which can be opened and closed again.
Zum Füllen der Kissen wird z.B. eine Füllmaschine der Firma Lorch verwendet, mit der eine abgewogene Menge an Füllmaterial in die Kissenhülle eingeblasen wird, nachdem dieses gegebenen¬ falls noch gereinigt wurde. Beim Einblasen der zuvor abgewogenen Menge an Füllmaterial bleibt oft ein Teil des Füllmaterials in der Füllmaschine und deren einzelnen Organen hängen. Dieses Füllmaterial muß von Hand nachgefüllt werden.For filling the pillows e.g. a filling machine from Lorch is used, with which a weighed amount of filling material is blown into the cushion cover after it has been cleaned, if necessary. When blowing in the previously weighed quantity of filling material, part of the filling material often gets caught in the filling machine and its individual organs. This filler must be refilled by hand.
Wird das Kissen oder die Decke z.B. von Hand mit Füllmateri¬ al gefüllt, so ist das eingefüllte Füllmaterial meist klumpig. Deshalb muß das Füllmaterial in dem gefüllten Kissen oder in der gefüllten Decke noch aufgelockert werden.If the pillow or blanket is e.g. filled with filling material by hand, the filling material filled is usually lumpy. Therefore, the filling material in the filled pillow or blanket must be loosened.
Die fertigen Kissen, Decken oder dergleichen weisen einThe finished pillows, blankets or the like have a
EHSAJZBLÄΓT REGEL 26 relativ großes Volumen auf, da in ihnen neben dem Füllmaterial auch sehr viel Luft vorhanden ist.EHSAJZBLÄΓT RULE 26 relatively large volume, because in addition to the filling material, there is also a lot of air.
Um dieses Volumen während des Transportes zu verringern, wurden z.B. schon fertig gefüllte Kissen in einer Kunststoff- hülle verpackt, wobei diese das Kissen aufnehmende Kunststoff- hülle unter Entzug eines Teils der darin enthaltenden Luft kom¬ primiert wurde und somit ein kleineres Volumen aufweist, als das gebrauchsfertige Kissen selbst. Dadurch wird für den Transport des fertigen Kissens bis hin zum Gebrauchsort weniger Volumen benötigt.In order to reduce this volume during transportation, e.g. already filled cushions are packed in a plastic cover, the plastic cover receiving the cushion being compressed while extracting part of the air contained therein and thus having a smaller volume than the ready-to-use cushion itself finished pillow to the place of use requires less volume.
Solcherart verpackte Kissen sind schwer verkäuflich und ihr Inhalt muß vor der Benutzung erst noch aufgelockert werden. Auch wird beim Zusammenpressen des Kissens die Hülle zerknittert.Pillows packaged in this way are difficult to sell and their contents have to be loosened before use. The cover is also crumpled when the pillow is pressed together.
Da die Kissenhüllen in der Regel schon fabrikationsseitig mit der Füllung gefüllt sind, ist der Endkunde darauf angewiesen Kissen mit einem vorgegebenen Füllgrad zu erwerben. Ein und dieselbe Größe eines Kissens mit unterschiedlichen Füllgraden zu befüllen erhöht die Lagerhaltung beim Produzenten und beim Han¬ del wesentlich.Since the pillow cases are usually already filled with the filling on the manufacturing side, the end customer is dependent on acquiring pillows with a specified filling level. Filling one and the same size of a pillow with different filling levels significantly increases the storage at the producer and at the trade.
Erfindunginvention
Der Erfindung liegt die Aufgabe zugrunde, insbesondere dem Endkunden die Möglichkeit zu geben, selbst ein Kissen, eine Decke oder dergleichen seinen Wünschen entsprechend herzustel¬ len. Darüber hinaus soll das Transportvolumen des Gegenstandes soweit als möglich verringert werden.The invention is based on the object, in particular of giving the end customer the possibility of producing a pillow, blanket or the like according to his wishes. In addition, the transport volume of the object should be reduced as much as possible.
Diese Aufgabe wird durch das Verfahren nach Anspruch 1 ge¬ löst.This object is achieved by the method according to claim 1.
Bei der Lösung der Aufgabe besteht die wesentliche Überle¬ gung darin, die Füllung getrennt von der Hülle bereitzustellen. Darüber hinaus wird die Füllung zum Zwecke des Transports kom¬ primiert. Damit kann der Endverbraucher nach seinen Vorstel¬ lungen eine Hülle mit einer bestimmten Füllmenge kombinieren.In solving the problem, the essential consideration is to provide the filling separately from the casing. In addition, the filling is compressed for the purpose of transportation. The end user can thus combine a casing with a specific filling quantity according to his ideas.
Durch das Verpacken der Füllung in eine Füllgutkartusche und die vorhandene Komprimierung der Füllung expandiert die Füllung, wenn die Füllgutkartusche in der Hülle richtig geöffnet wird, fast explosionsartig und die einzelnen Aggregate der Füllung verteilen sich gleichmäßig in der Hülle. Dabei nehmen sie imBy packing the filling in a filling cartridge and the existing compression of the filling, the filling expands almost explosively when the filling cartridge in the cover is opened correctly, and the individual aggregates of the filling are distributed evenly in the cover. They take in
Bfi IZBUrT REGE wesentlichen wieder das Volumen an, welches sie vor dem kom¬ primierten Verpacken hatten.Bfi IZBUrT REGE again essentially the volume which they had before the compressed packaging.
Nach dem Einfüllen der Füllung in die Hülle wird diese ver¬ schlossen, wozu die Hülle z.B. einen Reißverschluß aufweisen kann.After the filling has been filled into the envelope, the latter is closed, for which purpose the envelope e.g. can have a zipper.
Die Aggregate stehen in der Füllgutkartusche unter einem weitaus größeren Druck, als in der Hülle, in die sie hinein gefüllt werden. Dadurch können sich nach dem öffnen der Füll¬ gutkartusche durch den hohen Druck in der Füllgutkartusche die Aggregate zumindest zum Teil selbst expandierend in die Kissen¬ hülle füllen.The aggregates are under a much greater pressure in the filling cartridge than in the casing into which they are filled. As a result, after the filling cartridge has been opened due to the high pressure in the filling cartridge, the aggregates can, at least in part, fill themselves expanding into the cushion cover.
Trotz des Komprimierens der Aggregate, insbesondere der Faseraggregate, nehmen beim Expandieren derselben diese wieder etwa ihr ursprüngliches Volumen an.Despite the compression of the aggregates, in particular the fiber aggregates, when they expand, they return to their original volume.
Die gefüllte Hülle, insbesondere das gefüllte Kissen wird gemäß einem bevorzugten Verfahrensschritt nach dem Schließen der Hüllenöffnung, insbesondere unter Verteilung der Aggregate in der Hülle, geschüttelt oder verklopft. Durch das Schütteln und / oder Verklopfen der gefüllten Hülle kann auch bei noch zu¬ sammengeballten Aggregaten eine optimale Verteilung der Füllung in der Hülle erreicht werden.According to a preferred method step, the filled cover, in particular the filled cushion, is shaken or tapped after the cover opening has been closed, in particular while distributing the aggregates in the cover. By shaking and / or tapping the filled casing, an optimal distribution of the filling in the casing can be achieved even with aggregates still clumped together.
Gemäß einer bevorzugten Ausführungsform werden als Aggregate Faseraggregate aus räumlich zueinander angeordneten Fasern ver¬ wendet, die vorzugsweise sphärisch oder wirr miteinander verwik- kelt sind. Es können aber auch Federn, Daunen, Schaumstoffsticks und Gemische von einigen oder allen vier Arten von Aggregaten verwendet werden.According to a preferred embodiment, fiber aggregates of fibers arranged spatially to one another are used as aggregates, which are preferably spherically or tangledly interwoven. Feathers, down, foam sticks and mixtures of some or all four types of aggregates can also be used.
Aus der EP-A-0 203 469 ist es zwar bekannt, fertig produ¬ zierte Faseraggregate lose in Säcken zu verpacken und zum Kis¬ senhersteller oder dergleichen zu transportieren. Dabei werden die Faseraggregate unter mäßigen Drücken verdichtet, wobei dort Dichten zwischen 75 oder 100 g/1 untersucht wurden.From EP-A-0 203 469 it is known to pack finished fiber aggregates loosely in bags and to transport them to the pillow manufacturer or the like. The fiber aggregates are compacted under moderate pressures, where densities between 75 and 100 g / l were examined.
Dort wird beschrieben, daß die Faseraggregate aus dem Sack heraus ähnlich wie Daunen abgesaugt und in Kissen eingeblasen werden können. Dies hat aber mit der vorliegenden Erfindung nichts zu tun, da erfindungsgemäß die für eine bestimmte Hülle vorgesehenen Faseraggregate in einer Füllgutkartusche kompri¬ miert vorliegen und der Benutzer des gepolsterten Gegenstandes, wie Kissen, Decke, Polster oder dergleichen, alle AggregateIt describes that the fiber aggregates can be sucked out of the sack in a similar way to down and blown into pillows. However, this has nothing to do with the present invention, since, according to the invention, the fiber aggregates provided for a specific casing are present in compressed form in a filling material cartridge and the user of the padded object, such as a cushion, blanket, cushion or the like, all aggregates
ERSATZBLAΓT REGEL 26 einer Verpackung in eine Hülle dadurch einfüllen soll, daß die Füllgutkartusche in die Hülle hinein geöffnet wird, während nach dem bekannten Transportverfahren die Aggregate abgesaugt werden.SPARE BLADE RULE 26 to fill a package into a casing by opening the filling cartridge into the casing while the units are being sucked off by the known transport method.
Eine zur Ausübung des Verfahrens geeignete Füllgutkartusche zur Füllung einer Hülle mit Aggregaten, insbesondere Faseraggre¬ gaten, die mit den Aggregaten gefüllt ist, weist ein Volumen auf, welches einem Drittel bis einem Dreißigstel des Volumens der losen, nicht umhüllten oder verpackten Faseraggregate ent¬ spricht. Vorzugsweise weist die Füllgutkartusche ein Volumen auf, welches einem Fünftel bis einem Zwanzigstel, der losen, nicht umhüllten Aggregate entspricht.A filling cartridge suitable for carrying out the method for filling a casing with aggregates, in particular fiber aggregates, which is filled with the aggregates, has a volume which corresponds to one third to a thirtieth of the volume of the loose, non-enveloped or packaged fiber aggregates . The filling cartridge preferably has a volume which corresponds to one fifth to one twentieth of the loose, uncovered aggregates.
Entsprechend weist die mit den Aggregaten gefüllte Füll¬ gutkartusche ein Volumen auf, welches der Hälfte bis einem Zwan¬ zigstel des Volumens der Hülle entspricht.Accordingly, the filling cartridge filled with the units has a volume which corresponds to half to a twentieth of the volume of the casing.
Vorteilhafterweise besteht die Füllgutkartusche aus einem an seinen beiden Längsenden verschlossenen Schlauch, der zumindest mit seinem einen Ende, möglichst aber ganz in die geöffnete Hülle geschoben werden kann. Der die Füllgutkartusche bildende Schlauch kann aus Kunststoff bestehen.Advantageously, the filling cartridge consists of a tube which is closed at both of its longitudinal ends and which can be pushed at least with one end, but if possible completely into the opened casing. The hose forming the filling cartridge can be made of plastic.
Zweckmäßigerweise weist die Füllgutkartusche eine Sollbruch¬ stelle auf, die sich nach geringfügigen Öffnen durch den Druck der Aggregate selbst weiter öffnet und ein Expandieren der Ag¬ gregate zuläßt. Wird dann der Schlauch z.B. mittels eines Mes¬ sers von dem einen Ende desselben in Richtung auf das andere Ende zu, und damit auch in Richtung auf die Öffnung der Hülle des Kissen, der Decke oder dergleichen aufgeschlitzt, so expan¬ diert das Füllgut aus der Füllgutkartusche heraus in die Hülle.The product cartridge expediently has a predetermined breaking point which, after being slightly opened by the pressure of the units, opens further itself and permits the units to expand. If the hose is then e.g. by means of a knife slitting from one end thereof towards the other end, and thus also towards the opening of the cover of the cushion, blanket or the like, the filling material expands out of the filling material cartridge into the covering .
Gemäß einer besonderen Ausführungsform weist die Füllgutkar¬ tusche eine längliche Form, vorzugsweise die Form eines Kreiszy¬ linders, auf.According to a special embodiment, the filling cartridge has an elongated shape, preferably the shape of a circular cylinder.
• So kann ein länglicher, an einem Längsende offener Kunst¬ stoffbeutel mit der Füllung unter starker Kompression derselben gefüllt werden und nach dem Füllen dieses Längsende verschlossen werden.In this way, an elongated plastic bag that is open at one longitudinal end can be filled with the filling with strong compression thereof and can be closed after this longitudinal end has been filled.
Eine zur Ausübung des Verfahrens geeignete Hülle, wie Kis¬ senhülle, Deckenhülle, oder dergleichen, weist bevorzugt eine verschließbare Öffnung, insbesondere einen Reißverschluß auf, den der Benutzer des Kissen, nachdem er dasselbe mittels der aus der Füllgutkartusche expandierten Faseraggregate gefüllt hat,A cover suitable for carrying out the method, such as a cushion cover, cover cover, or the like, preferably has a closable opening, in particular a zipper, which the user of the cushion, after having filled it by means of the fiber aggregates expanded from the filling material cartridge,
ERSAΓZBLATT ( EGEL 26) schließen kann.SUBSTITUTE SHEET (EGEL 26) can close.
Die Dichte der Aggregate in g/1 wird durch die Messung des Gewichtes und des Volumens der Aggregate bei einem bestimmten Druck bestimmt (Dichte = Gewicht / Volumen) . Während die Messung des Gewichtes durch Wiegen einer bestimmten Menge an Aggregaten vollzogen wird, soll im folgenden die Messung der verschiedenen Volumina näher erläutert werden.The density of the aggregates in g / 1 is determined by measuring the weight and volume of the aggregates at a certain pressure (density = weight / volume). While the measurement of the weight is carried out by weighing a certain amount of aggregates, the measurement of the different volumes will be explained in more detail below.
Die abgewogene Menge an Aggregaten wird lose und locker in einen Meßzylinder eingefüllt, wobei die Aggregate beim Einbrin¬ gen nicht zusammenballen sollten. Auf die eingefüllten Aggregate wird, um reproduzierbare Ergebnisse zu erhalten, eine ebene Platte mit einem Außendurchmesser, der geringfügig kleiner ist, als der Innendurchmesser des Meßzylinders aufgelegt. Die Masse der Platte ist so bemessen, daß sie auf die Säule aus Aggregaten einen Druck von 0,1 cN/cm2 ausübt. Weiterhin ist darauf zu ach¬ ten, daß das Volumen der Füllung in Bezug auf die Geometrie des Meßzylinders so bemessen ist, daß die Höhe der belasteten Säule aus Aggregaten mindestens einem Drittel des Innendurchmessers des Meßzylinders beträgt.The weighed amount of aggregates is poured loosely and loosely into a measuring cylinder, the aggregates should not agglomerate when introduced. In order to obtain reproducible results, a flat plate with an outer diameter that is slightly smaller than the inner diameter of the measuring cylinder is placed on the filled aggregates. The mass of the plate is such that it exerts a pressure of 0.1 cN / cm 2 on the column of aggregates. It should also be ensured that the volume of the filling is dimensioned in relation to the geometry of the measuring cylinder in such a way that the height of the loaded column of units is at least one third of the inside diameter of the measuring cylinder.
Die Einfüllhöhe der Aggregate wird bestimmt, woraus sich das eingefüllte Volumen der Aggregate ergibt. Der Quotient aus Ge¬ wicht der Aggregate und Volumen der Aggregate ergibt die Dichte der losen Aggregate.The filling level of the aggregates is determined, which results in the filled volume of the aggregates. The quotient of the weight of the aggregates and the volume of the aggregates gives the density of the loose aggregates.
Für die Bestimmung des maximalen Volumens der Hülle, und damit zur Ermittlung der Dichte der Aggregate in einer Hülle, z.B. der Kissenhülle, wird die Hülle mit kleinen Styroporkugeln prall gefüllt, woraufhin das Volumen dieser Menge an Styroporku¬ geln in einem Meßzylinder gemessen wird. Zur Messung werden Styroporkugeln benutzt, die einen Durchmesser zwischen 2 mm und 4 mm aufweisen.For the determination of the maximum volume of the casing, and thus for the determination of the density of the aggregates in a casing, e.g. of the cushion cover, the cover is filled to the brim with small styrofoam balls, whereupon the volume of this amount of styrofoam balls is measured in a measuring cylinder. Polystyrene balls with a diameter between 2 mm and 4 mm are used for the measurement.
Analog wird für die Bestimmung der Dichte der Aggregate in der Füllgutkartusche vorgegangen; auch hier wird mittels Styro¬ porkugeln das Volumen der Füllgutkartusche bestimmt, wobei immer von einer gleichen Menge an Aggregaten, d.h. einem gleichen Gewicht ausgegangen wird.The same procedure is used to determine the density of the aggregates in the filling cartridge; here too, the volume of the filling cartridge is determined by means of polystyrene balls, whereby an equal amount of aggregates, i.e. an equal weight is assumed.
Dadurch daß immer das gleiche Gewicht an Aggregaten benutzt wird, gibt das Verhältnis der drei verschiedenen Volumina das Verhältnis der drei verschiedenen Dichten und - umgekehrt pro¬ portional dazu - den Verdichtungsfaktor an. So werden z.B. in ein Kissen, dessen Hülle die Außenmaße 50 cm * 70 cm aufweist, Faseraggregate mit einem Gesamtgewicht von 450 g eingefüllt. Diese Faseraggregate weisen im losen Zustand eine Dichte von etwa 12 g/1 auf, d.h., sie haben ein Volumen von 37,5 1. Wird diese Menge von 450 g Faseraggregaten in eine Füll¬ gutkartusche mit einem Verdichtungsverhältnis von 1:20 gepreßt, dann wird das Volumen von 37,5 1 auf ca. 1,9 1 verringert. Die Dichte in der Füllgutkartusche beträgt dann 240 g/1.Because the same weight of units is always used, the ratio of the three different volumes indicates the ratio of the three different densities and - inversely proportional to this - the compression factor. For example, fiber aggregates with a total weight of 450 g are filled into a pillow, the shell of which has the external dimensions 50 cm * 70 cm. In the loose state, these fiber aggregates have a density of about 12 g / l, ie they have a volume of 37.5 l. If this amount of 450 g fiber aggregates is pressed into a filling cartridge with a compression ratio of 1:20, then the volume is reduced from 37.5 1 to approx. 1.9 1. The density in the filling cartridge is then 240 g / 1.
Da die Hülle, in die die Faseraggregate eingefüllt werden sollen, ein weitaus größeres Volumen aufweist, als die Füll¬ gutkartusche, nämlich bei der hier beschriebenen Ausführungsform etwa 25 1, und die Faseraggregate reversibel komprimierbar sind, können sich die Faseraggregate in der Hülle wieder entspannen und füllen die Hülle voll aus. In der Hülle, z.B. einem fertig gefüllten, unbelasteten Kopfkissen, beträgt die Dichte z.B. 18 g/1, es liegt also gegenüber den losen Faseraggregaten eine Verdichtungsfaktor von 1:1,5.Since the casing into which the fiber aggregates are to be filled has a volume which is far greater than that of the filling cartridge, namely approximately 25 liters in the embodiment described here, and the fiber aggregates are reversibly compressible, the fiber aggregates in the casing can relax again and fill the envelope completely. In the envelope, e.g. a fully filled, unloaded pillow, the density is e.g. 18 g / 1, so there is a compression factor of 1: 1.5 compared to the loose fiber aggregates.
Die Verdichtung von losen Faseraggregaten zu in Kissen ge¬ füllten Faseraggregaten zu in der Füllgutkartusche befindlichen Faseraggregaten verhalten sich dann wie 1:1,5:20.The compression of loose fiber aggregates to fiber aggregates filled in pillows to fiber aggregates located in the filling cartridge then behave as 1: 1.5: 20.
Wird nun eine Kissenhülle gewählt, deren maximales Volumen nur halb so groß ist, wie das Volumen der oben beschriebenen Hülle, aber dieselbe mit Faseraggregaten gefüllte Füllgutkartu¬ sche zum Füllen dieser Hülle benutzt, so erhöht sich die Dichte der Faseraggregate in diesem Kissen und die Verdichtungsverhält¬ nisse betragen 1:3:20.If a cushion cover is now selected, the maximum volume of which is only half as large as the volume of the cover described above, but the same filling material cartridge filled with fiber aggregates is used to fill this cover, the density of the fiber aggregates in this cushion and the compression ratio increase ¬ nits are 1: 3: 20.
Ein solches Kissen ist wesentlich fester als das zuvor be¬ schriebene Kissen.Such a pillow is much firmer than the pillow described above.
Auch ist es möglich bei gleichem maximalen Kissenvolumen den Inhalt von zwei Füllgutkartuschen in die eine Hülle zu füllen. • Daraus ergibt sich, daß die Lagerhaltung im Handel kleiner gehalten werden kann, da die vom Kunden gewünschte Kissengröße und Füllmenge vom Kunden zusammengestellt wird und nicht vom Kissenhersteller.It is also possible to fill the contents of two filling cartridges into one sleeve with the same maximum pillow volume. • This means that the inventory in retail can be kept smaller since the pillow size and filling quantity requested by the customer is put together by the customer and not by the pillow manufacturer.
Zum Füllen einer Füllgutkartusche wird ein länglicher, an seinem einen Ende offener Kunststoffschlauch über das eine Ende eines Füllrohres geschoben. Dabei entspricht der Außendurch¬ messer dieses Rohres etwa dem Durchmesser des Schlauches, so daß der Schlauch stramm auf dem Rohr aufsitzt. In das freie Ende desTo fill a filling cartridge, an elongated plastic tube, which is open at one end, is pushed over one end of a filling tube. The outside diameter of this tube corresponds approximately to the diameter of the tube, so that the tube sits tightly on the tube. In the free end of the
(REGEL 26) 7 (RULE 26) 7
Rohres wird die gewünschte Menge an Aggregaten, z.B. Faseraggre¬ gaten eingefüllt und mittels eines in das Rohr eingeschobenen Stempels werden die Aggregate in den Schlauch gepreßt. Dieser gleitet gegen einen auf sein freies Ende wirkenden Widerstand so weit von dem Füllrohr ab, bis das auf die Aggregate drückende Ende des Stempels aus dem Rohr herausgedrückt wurde. Daraufhin wird das bisher noch offene Ende des Schlauches verschlossen, was z.B. mittels eines Bandes oder mittels Abschweißen des Schlauches erfolgen kann. Das gegebenenfalls überstehende Ende des Schlauches wird entfernt.Rohres the desired amount of units, e.g. Filled in fiber aggregates and the aggregates are pressed into the tube by means of a punch inserted into the tube. This slides against a resistance acting on its free end from the filling tube until the end of the plunger pressing on the aggregates has been pressed out of the tube. Then the previously open end of the hose is closed, which e.g. can be done by means of a band or by welding the hose. The possibly protruding end of the hose is removed.
Beim Transport der Füllgutkartusche und der Hülle kann eine Füllgutkartusche mit einer für diese Hüllengröße erforderlichen minimalen Füllmenge im Innern der Hülle an deren der Öffnung abgewandten Ende angeordnet sein, wobei der Rest der Hülle um die schon eingehüllte Füllgutkartusche herum gewickelt ist. Dadurch wird diese Kartusche beim Transport besser geschützt.When transporting the filling cartridge and the sleeve, a filling cartridge with a minimum filling quantity required for this sleeve size can be arranged inside the sleeve at its end facing away from the opening, the rest of the sleeve being wrapped around the already filled-in cartridge. This protects the cartridge better during transport.
Je nach Füllgrad, d.h. je nach Kompressionsverhältnis, der Füllgutkartusche, kann diese aus unterschiedlich dicken Kunststoff-Folienmaterial hergestellt sein. Weist das Füllgut in der Kartusche ein Volumen auf, welches etwa einem Drittel des Volumens des nicht verpackten und nicht komprimierten Füllgutes entspricht, so kann das verwendete Folienmaterial eine Dicke von 20 um aufweisen. Da bei größerem Kompressionsverhältnis der Druck in der Kartusche wesentlich größer ist, muß das Folienma¬ terial dann auch dicker sein. Bei einem Kompressionsverhältnis von 1 : 10 liegt die Dicke dann bei etwa 80 um. Die Dicke hängt natürlich auch von der Art des Folienmaterials ab. Depending on the degree of filling, i.e. depending on the compression ratio, the filling cartridge, this can be made of different thickness plastic film material. If the filling material in the cartridge has a volume which corresponds to approximately one third of the volume of the non-packaged and non-compressed filling material, the film material used can have a thickness of 20 μm. Since the pressure in the cartridge is much greater with a larger compression ratio, the film material must then also be thicker. With a compression ratio of 1:10, the thickness is then about 80 µm. The thickness of course also depends on the type of film material.
