Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Beheizen von kontinuierlichen Transportvorrichtungen, insbesondere in Konfektioniermaschinen.The present invention relates to a device for heating of continuous transport devices, especially in Packaging machines.

Allgemein werden in solchen Maschinen die Produkte, die bei­ spielsweise aus Gruppen von Zigaretten bestehen, durch ein oder mehrere Einwickelräder in entsprechende flache Abschnitte einge­ wickelt, um starre Päckchen zu bilden, welche aneinanderliegende und miteinander verklebte Teile aufweisen.Generally, in such machines the products that are used in for example consist of groups of cigarettes, by one or several wrapping wheels inserted into corresponding flat sections wraps to form rigid packages that are contiguous and have parts glued together.

Beim Austritt aus einem Einwickelrad werden die Päckchen an einen Förderer zum Trocknen geleitet, der den Zweck hat, das Klebematerial, das die aneinanderliegenden Teile miteinander verbindet, zu trocknen, und der normalerweise aus einem Paar von kontinuierlichen Transportvorrichtungen, überlicherweise Bänder, die parallel zueinander angeordnet sind, besteht. Die kontinuierli­ chen Transportvorrichtungen halten die Päckchen und lassen sie vorlaufen, wobei sie mit diesen an deren aneinanderliegenden Tei­ len in Kontakt kommen, um sie während des Trocknens des sich dazwischen befindlichen Klebematerials in der richtigen Position zu halten.When leaving a wrapping wheel, the packages are on directed a conveyor to dry, the purpose of which is Adhesive material that joins the adjacent parts together combines to dry, and which usually consists of a pair of continuous transport devices, usually belts, which are arranged parallel to each other. The continuous Chen transport devices hold the packages and leave them run ahead, with them at their adjacent parts len come in contact with them while drying the adhesive material in between in the correct position to keep.

Das Trocknen des Klebematerials erfolgt durch das Beheizen der kontinuierlichen Transportvorrichtungen.The adhesive material is dried by heating the  continuous transport devices.

Heutzutage besteht das am meisten angewandte Verfahren zum Beheizen der genannten kontinuierlichen Transportvorrichtungen darin, daß die kontinuierlichen Transportvorrichtungen selbst ei­ nem heißen Luftstrom ausgesetzt sind, der von entsprechenden Ventilatoren erzeugt wird. Als Alternative hat man vorgesehen, die kontinuierlichen Transportvorrichtungen in einer ringförmigen Bahn zu führen, die um eine Heizvorrichtung läuft, bestehend aus einem Behälter für das Schmieröl der Konfektioniermaschine, zu welcher die kontinuierlichen Transportvorrichtungen gehören.Nowadays the most widely used method is Heating of said continuous transport devices in that the continuous transport devices themselves exposed to hot airflow from the appropriate Fans is generated. As an alternative, the continuous transport devices in an annular To run web that runs around a heater consisting of a container for the lubricating oil of the packaging machine which includes the continuous transport devices.

Es wird als notwendig erachtet, darauf hinzuweisen, daß die Päckchen bei einer Temperatur beheizt werden müssen, die in­ nerhalb eines eher engen Wertebereiches variieren kann, um zu vermeiden, das bei zu hohen Temperaturen ein Verbrennen der Päckchen auftritt oder bei unzureichenden Temperaturen nicht das vollkommene Trocknen der Klebematerialien erhalten wird.It is considered necessary to point out that the Packets must be heated at a temperature that is in can vary within a rather narrow range of values in order to Avoid burning the at high temperatures Parcel occurs or not at insufficient temperatures perfect drying of the adhesive materials is obtained.

Es wird festgestellt, daß, obwohl die beschriebenen Transport­ vorrichtungen auf eine theoretische optimale Temperatur oder auf eine unwesentlich höhere Temperatur gebracht werden, die Klebe­ materialien nicht immer auf korrekte Weise trocknen, weshalb es sich manchmal ergibt, daß aufgrund der mangelnden Trocknung sich die aneinanderliegenden Teile sich beim Austritt aus den Transportvorrichtungen von dem Körper des Päckchens lösen.It is noted that although the transportation described devices to a theoretical optimum temperature or on the adhesive is brought to a slightly higher temperature materials do not always dry properly, which is why sometimes it turns out that due to the lack of drying the contiguous parts come out of the Detach transport devices from the body of the package.

Beim Messen der Temperatur an den nach den erwähnten Verfah­ ren beheizten kontinuierlichen Transportvorrichtungen kann man feststellen, daß die zur vollständigen Trocknung der Klebemate­ rialien erforderliche Temperatur sich nur an der Oberflächen­ schicht der kontinuierlichen Transportvorrichtungen selbst hält. Unter diesen Umständen sind die kontinuierlichen Transportvor­ richtungen natürlich nicht in der Lage, die notwendige Wärme­ menge an die Päckchen abzugeben, insbesondere bei hohen Be­ triebsgeschwindigkeiten.When measuring the temperature on the according to the above-mentioned procedure Ren heated continuous transport devices can  find that the complete drying of the adhesive rialien required temperature only on the surfaces layer of continuous transport devices itself. In these circumstances, the continuous transportation is ahead directions of course unable to provide the necessary heat amount to be given to the parcels, especially with high loads driving speeds.

Zweck der vorliegenden Erfindung ist der, eine Vorrichtung zum Beheizen von kontinuierlichen Transportvorrichtungen zu liefern, die in der Lage ist, die von diesen transportierten Produkte auf solche Weise zu erwärmen, daß die oben beklagten Nachteile vermieden werden.The purpose of the present invention is to provide a device for To provide heating for continuous transport devices, who is able to get the products transported by these to heat in such a way that the disadvantages lamented above be avoided.

Nach der vorliegenden Erfindung wird eine Vorrichtung zum Beheizen von kontinuierlichen Transportvorrichtungen hergestellt, insbesondere in Maschinen zur Konfektionierung von Produkten, wobei die genannten Produkte von einer äußeren Umhüllung um­ geben sind, welche aneinanderliegende und miteinander verklebte Teile aufweist, und wobei sie dazu bestimmt sind, von den ge­ nannten kontinuierlichen Transportvorrichtungen entnommen zu werden, dadurch gekennzeichnet, daß sie Heizstrahlungsmittel enthält, die an einem Abschnitt einer entsprechenden konti­ nuierlichen Transportvorrichtung angeordnet sind und arbeiten und dazu dienen, die genannte kontinuierliche Transportvorrich­ tung zu beheizen und die Wärmekapazität derselben auf einen solchen Wert anzuheben, daß es der kontinuierlichen Transport­ vorrichtung selbst erlaubt ist, Wärme für eine Dauer und in einer Menge an die genannten verklebten Teile der Produkte abzuge­ ben, ausreichend für deren vollkommene Trocknung; wobei Steuer- und Auslösemittel vorgesehen sind, die dazu dienen, die Temperatur der jeweiligen kontinuierlichen Transportvorrichtung zu erfassen und auf einem vorbestimmten Wert zu halten.According to the present invention, an apparatus for Heating of continuous transport devices manufactured, especially in machines for the assembly of products, said products being surrounded by an outer wrapper are which are adjacent and glued together Has parts, and wherein they are intended by the ge called continuous transport devices are characterized in that they radiant heat contains that at a section of a corresponding cont nuclear transport device are arranged and work and serve the said continuous transport device heating and the heat capacity of the same at one to increase such value that it is continuous transportation  device itself is allowed to heat for a duration and in one Deduct the amount of the glued parts of the products mentioned ben, sufficient for their complete drying; in which Control and triggering means are provided, which serve the Temperature of the respective continuous transport device to detect and keep at a predetermined value.

Die Erfindung wird nachstehend detaillierter beschrieben, und zwar unter Zuhilfenahme der Zeichnungen, die eine rein als Beispiel gedachte und nicht begrenzende Verwirklichungsform darstellen, und von denenThe invention is described in more detail below, and with the help of the drawings, which are purely as Example of an imaginary and non-limiting form of realization represent, and of those

Abb. 1 eine schematische Seitenansicht eines Förderers zum Trocknen zeigt, der mit der Vorrichtung zum Behei­ zen nach der vorliegenden Erfindung versehen ist und zu einer Konfektioniermaschine gehört, von der nur ein Ein­ wickelrad gezeigt wird; Fig. 1 shows a schematic side view of a conveyor for drying, which is provided with the heating device according to the present invention and belongs to a packaging machine, of which only one winding wheel is shown;

Abb. 2 zeigt eine schematische Seitenansicht in vergrös­ serter Form von einem Teil des Förderers zum Trocknen aus Abb. 1; Fig. 2 shows a schematic side view in enlarged form of part of the conveyor for drying from Fig. 1;

Abb. 3 zeigt schematisch ein weiteres Detail des Förde­ rers zum Trocknen aus den vorstehenden Abbildungen. Fig. 3 shows schematically another detail of the conveyor for drying from the above figures.

Unter Bezugnahme auf die beiliegenden Abbildungen ist mit 2 ein Förderer zum Trocknen bezeichnet, der zu einer Konfektionierma­ schine 3 gehört, welche ein Einwickelrad 4 enthält, das den Förderer zum Trocknen 2 selbst mit den Päckchen 8 beschickt, die aus einer äußeren Umhüllung 6 bestehen, welche aneinander­ liegende und miteinander verklebte Teile 7 aufweist. In diesem besonderen Falle enthält die äußere Umhüllung 6 Gruppen von Zigaretten, die nur in Abb. 2 schematisch sichtbar sind, wo­ bei die Zigaretten gestrichelt angedeutet und mit 5 bezeichnet sind.With reference to the accompanying figures, 2 denotes a conveyor for drying, which belongs to a packaging machine 3 , which contains a wrapping wheel 4 , which feeds the conveyor 2 for drying itself with the packages 8 , which consist of an outer envelope 6 , which has mutually adjacent and glued parts 7 . In this particular case, the outer wrapper contains 6 groups of cigarettes, which are only schematically visible in Fig. 2, where the cigarettes are indicated by dashed lines and denoted by 5 .

Das Einwickelrad 4 der Konfektioniermaschine 3 beschickt den Förderer zum Trocknen 2 mit den einzelnen Päckchen 8, die kor­ rekt ausgebildet und bereit sind, der Wärmewirkung des Förderers zum Trocknen 2 selbst unterzogen zu werden, um somit die kom­ plette Trocknung der Klebematerialien zu bewirken, die hier nicht bezeichnet sind und sich zwischen den aneinanderliegenden Teilen 7 der Päckchen 8 selbst befinden.The wrapping wheel 4 of the packaging machine 3 feeds the conveyor for drying 2 with the individual packets 8 , which are correctly configured and are ready to be subjected to the thermal effect of the conveyor for drying 2 itself, in order to thus effect the complete drying of the adhesive materials are not designated here and are located between the adjacent parts 7 of the packets 8 themselves.

Mit dem Zweck zu vermeiden, daß die aneinanderliegenden Teile 7, die noch nicht vollkommen miteinander verklebt sind, sich lösen und damit das Auseinanderfallen der Umhüllung 6 bewir­ ken, wird der Förderer zum Trocknen 2 aus zwei horizontalen kontinuierlichen Transportvorrichtungen 9 gebildet, die nach einer vertikalen Richtung übereinander angeordnet sind. Diese kontinu­ ierlichen Transportvorrichtungen 9 sind im Verhältnis zu einer ho­ rizontalen Ebene spiegelartig einander zugewandt angeordnet und befinden sich in einem solchen gegenseitigen Abstand voneinan­ der, daß sie mit ihren einander zugewandten Trums 9a mit den entgegengesetzten aneinanderliegenden Teilen 7 der Päckchen 8 Kontakt haben und diese leicht andrücken, um das Einhalten von deren korrekter Position zu begünstigen. With the purpose of avoiding that the abutting parts 7 , which are not yet completely glued together, come loose and thus cause the sheathing 6 to fall apart, the conveyor for drying 2 is formed from two horizontal continuous transport devices 9 which are arranged according to a vertical Direction are arranged one above the other. These continuous transport devices 9 are arranged in a mirror-like manner facing each other in relation to a ho horizontal plane and are located at such a mutual distance from one another that they have contact with their mutually facing strands 9 a with the opposing adjacent parts 7 of the packet 8 and these press lightly to help maintain their correct position.

Jede kontinuierliche Transportvorrichtung 9 ist aus einem ringför­ mig geschlossenen Transportband 10 gebildet, das über entspre­ chende Umlenkscheiben 11 läuft, von denen zwei in der Nähe des Einwickelrades 4 angeordnet sind. Die nicht einander zuge­ wandten Trums der Transportbänder 10 laufen zu einem Teil um Bandspannscheiben 22, welche diese Trums in zwei aufeinander­ folgende Abschnitte trennen, die mit 9b, 9c bezeichnet sind. Von diesen beiden Abschnitten ist der mit 9b bezeichnete in der Nähe des Einwickelrades 4 angeordnet und ist der Wirkung einer ent­ sprechenden Heizvorrichtung 1 unterzogen.Each continuous transport device 9 is formed from a ringför shaped closed conveyor belt 10 which runs over corre sponding deflection disks 11 , two of which are arranged in the vicinity of the wrapping wheel 4 . The non-facing strands of the conveyor belts 10 run in part around belt tensioning disks 22 , which separate these strands into two successive sections, which are designated by 9 b, 9 c. Of these two sections, the one designated 9 b is arranged in the vicinity of the wrapping wheel 4 and is subjected to the action of a corresponding heating device 1 .

In der Abb. 1 sind die Vorschubrichtungen der verschiede­ nen Trums 9a, 9b, 9c der kontinuierlichen Transportvorrichtungen 9 angezeigt, und die Pfeile, welche diese Vorschubrichtungen an­ zeigen, sind mit Fa, Fb und Fc bezeichnet. Beim Betrachten dieser Vorschubrichtungen kann bemerkt werden, daß sich die einander zugewandten Trums 9a von dem Einwickelrad 4 fort bewegen, und daß sich die Abschnitte 9b dagegen zu dem Einwickelrad 4 selbst hin bewegen. Tatsächlich übernehmen die einander zuge­ wandten Trums 9a die Päckchen 8 von dem Einwickelrad 4 und leiten sie weiter, wobei diese beheizt werden, während die Ab­ schnitte 9b jeweils von einer Heizvorrichtung 1 erwärmt werden, die unmittelbar vor dem Entnahmebereich der Päckchen 8 ange­ ordnet ist.In Fig. 1, the feeding directions of Various NEN strand 9 a, 9 b, 9 c of the continuous transport devices 9 shown and the arrows showing these feed directions to are designated by Fa, Fb and Fc. When looking at these feed directions it can be noticed that the mutually facing strands 9 a move away from the wrapping wheel 4 , and that the sections 9 b, on the other hand, move towards the wrapping wheel 4 itself. In fact, the mutually facing runs of 9 take a the packets 8 of the wrapping wheel 4 and forward it, which are heated, while the Ab sections 9 b respectively of a heater 1 to be heated, which is immediately before the removal area of the packages 8 arranges is.

Eine jede Heizvorrichtung 1 enthält Heizmittel 12, die dicht an dem Abschnitt 9b der jeweiligen kontinuierlichen Transportvor­ richtung 9 angeordnet sind und dort arbeiten. Diese Heizmittel 12 sind in der Lage, die kontinuierliche Transportvorrichtung zu be­ heizen und die Wärmekapazität auf einen solchen Wert anzuheben, daß es diesen möglich ist, an die verklebten Teile 7 der Päckchen 8 für eine Dauer und in einer Menge abzugeben, die ausreichend sind, deren vollständige Trocknung zu bewirken. Zu der Heizvorrichtung 1 gehören Steuer- und Auslösemittel 13, in der Lage, die Temperatur der jeweiligen kontinuierlichen Trans­ portvorrichtung 9 zu erfassen und konstant zu halten.Each heating device 1 contains heating means 12 which are arranged close to the section 9 b of the respective continuous Transportvor direction 9 and work there. These heating means 12 are able to heat the continuous transport device and to increase the heat capacity to such a value that it is possible to deliver them to the glued parts 7 of the packets 8 for a period and in an amount sufficient to effect their complete drying. To the heating device 1 include control and triggering means 13 , capable of detecting the temperature of the respective continuous trans port device 9 and keeping it constant.

Als Heizmittel 12 werden Erzeugungsmittel 14 von elektromagne­ tischer Energie verwendet, welche ohne jeden Kontakt mit der je­ weiligen kontinuierlichen Transportvorrichtung 9 arbeiten. Vor­ zugsweise sind diese Mittel 14 Heizstrahlungsmittel und bestehen vorzugsweise aus Infrarotstrahlern 14 in Keramik. Die Besonder­ heit dieser Heizmittel 12 liegt in der Tatsache, daß diese ihre Aufgabe erfüllen, indem sie nicht thermische, sondern elektro­ magnetische Energie übertragen, die von dem Band 10 und in dessen gesamter Stärke aufgenommen wird; dadurch wird eine Er­ höhung der Wärmekapazität bei gleicher Oberflächentemperatur bewirkt, und zwar im Gegenteil zu dem was bei den herkömmli­ chen Vorrichtungen geschieht, bei denen die Beheizung durch Konvektion erfolgt und nur die Oberflächenschicht des Bandes 10 betrifft, während die tieferliegenden Schichten desselben eine niedrigere Temperatur aufweisen.As heating means 12 generating means 14 of electromagnetic energy are used, which work without any contact with the respective continuous transport device 9 . Before these means are preferably 14 radiant heaters and preferably consist of infrared radiators 14 in ceramic. The peculiarity of these heating means 12 lies in the fact that they do their job by not transferring thermal but electromagnetic energy which is absorbed by the band 10 and in its entire strength; thereby causing an increase in heat capacity at the same surface temperature, contrary to what is happening in the conventional devices, in which heating is by convection and only affects the surface layer of the belt 10 , while the underlying layers of the same have a lower temperature exhibit.

Das Anheben der Temperatur und der Wärmekapazität der konti­ nuierlichen Transportvorrichtung 9 wäre jedoch nicht ausreichend, um eine korrekte Trocknung des Klebematerials zu gewährleisten, da das Transportband 10 je nach Notwendigkeit mit mehr oder weniger hoher Geschwindigkeit vorlaufen kann.However, raising the temperature and the heat capacity of the conti nuous transport device 9 would not be sufficient to ensure proper drying of the adhesive material to ensure that the conveyor belt 10 may be pre-run as needed with more or less high speed.

Um die Kontinuität und den einwandfreien Betrieb des Förderers zum Trocknen 2 garantieren zu können, enthalten die Steuer- und Auslösemittel 13 Temperaturfühler 15 sowie eine Steuer- und Auslöseeinheit 16, an welche im Eingang die Temperaturfühler 15 und im Ausgang Regler 17 angeschlossen sind, in der Lage, die Wärmekapazität der kontinuierlichen Transportvorrichtung zu va­ riieren. Die Steuer- und Auslöseeinheit 16 kann aus einem Ther­ mostat gebildet sein, während die Temperaturfühler 15 aus Infra­ rotsensoren bestehen, in der Lage, die Temperatur des sich bewe­ genden Transportbandes 10 zu erfassen.In order to be able to guarantee the continuity and the flawless operation of the conveyor for drying 2 , the control and triggering means 13 contain temperature sensors 15 and a control and triggering unit 16 , to which the temperature sensors 15 are connected in the input and controller 17 in the output, in which Able to vary the heat capacity of the continuous transport device. The control and triggering unit 16 can be formed from a thermostat, while the temperature sensors 15 consist of infrared sensors, capable of detecting the temperature of the moving conveyor belt 10 .

Was die Regulierung der Wärmekapazität des Transportbandes 10 betrifft, so sind mit der Steuer- und Auslöseeinheit 16 sei es die Strahler 14 wie auch die Regler 17 verriegelt. Die Steuer- und Auslöseeinheft 16 reguliert die Betriebstemperatur der Strahler 14, während die Regler 17 eine ausreichende Regulierschnelligkeit dieser Temperatur gewährleisten.As regards the regulation of the heat capacity of the conveyor belt 10, so are the control and trip unit 16, it is 14 locks the radiator as well as the controller 17th The control and trigger unit 16 regulates the operating temperature of the radiators 14 , while the regulators 17 ensure a sufficient regulating speed of this temperature.

In der Abb. 3 sind zwei verschiedene Verwirklichungsfor­ men der Regler 17 gezeigt.In Fig. 3, two different realization forms of the controller 17 are shown.

Bei einer ersten Verwirklichungsform bestehen die Regler 17 aus einem ersten linearen Trieb 18, dessen erstes Ende an einen Rahmen 19 angeschlossen ist, welcher die verschiedenen Strahler 14 trägt, und dessen zweites Ende an eine hier nicht gezeigte fest­ stehende Trägerstruktur angeschlossen ist. Der lineare Trieb 18 bewegt die Strahler 14 parallel zu sich selbst, wobei er sie an den Abschnitt 9b annähert oder von diesem entfernt.In a first embodiment, the controllers 17 consist of a first linear drive 18 , the first end of which is connected to a frame 19 which supports the various radiators 14 , and the second end of which is connected to a fixed support structure, not shown here. The linear drive 18 moves the radiator 14 parallel to itself, wherein he approaches b to the portion 9 or removed therefrom.

Natürlich wird ein Entfernen der Strahler 14 hervorgerufen, um die Wärmekapazität zu senken, und entsprechend ein Annähern, um die Wärmekapazität der kontinuierlichen Transportvorrichtung 9 zu erhöhen.Of course, removal of the radiators 14 is brought about in order to reduce the heat capacity and, accordingly, approximation to increase the heat capacity of the continuous transport device 9 .

Bei einer zweiten Verwirklichungsform werden die Regler 17 aus Ventilatoren gebildet, die wiederum aus einem Erzeuger 20 für eine Strömung bestehen, normalerweise Luft, und aus wenigstens einer Abgabedüse 21, die auf solche Weise ausgerichtet ist, daß sie Luft in den Zwischenraum leitet, der sich zwischen den Strah­ lern 14 und dem Abschnitt 9b der kontinuierlichen Transportvor­ richtung 9 befindet.In a second embodiment, the regulators 17 are constituted by fans, which in turn consist of a flow generator 20 , usually air, and at least one discharge nozzle 21 , which is oriented in such a way that it directs air into the space which flows between the beamers 14 and the section 9 b of the continuous Transportvor direction 9 is located.

Es kann festgestellt werden, daß die Abgabedüse 21 eine Be­ schleunigung beim Senken der Wärmekapazität der kontinuierli­ chen Transportvorrichtung 9 bewirkt. Dies ist darauf zurückzu­ führen, daß die Abgabedüse 21 sei es die kontinuierliche Trans­ portvorrichtung 9 wie auch die Strahler 14 abkühlt, welche, bevor sie erneut die Betriebstemperatur erreichen, eine verhältnismäßig lange Zeit benötigen.It can be seen that the discharge nozzle 21 causes acceleration when lowering the heat capacity of the continuous transport device 9 . This is due to the fact that the dispensing nozzle 21 cools the continuous trans port device 9 as well as the radiators 14 , which require a relatively long time before they reach the operating temperature again.

Im Gegenteil dazu erlaubt der lineare Trieb 18 ein langsames Sen­ ken, aber auch ein schnelles Aufholen der Wärmekapazität der kontinuierlichen Transportvorrichtung 9. Diese Tatsache kommt daher, daß kein Mittel zur Abkühlung verwendet wird, wie im Falle der Abgabedüse 21, sondern das Heizmittel entfernt wird, so daß die Wärmekapazität der kontinuierlichen Transportvorrich­ tung 9 durch Wärmedispersion von selbst abnimmt. In dem Au­ genblick, in dem es sich als erforderlich erweist, die Wärmekapa­ zität der kontinuierlichen Transportvorrichtung 9 zu erhöhen, genügt es, das Heizmittel, das sich auf seiner Betriebstemperatur befindet, heranzuführen.On the contrary, the linear drive 18 allows a slow Sen ken, but also a quick recovery of the heat capacity of the continuous transport device 9th This fact comes from the fact that no means of cooling is used, as in the case of the dispensing nozzle 21 , but the heating means is removed, so that the heat capacity of the continuous transport device 9 decreases automatically due to heat dispersion. At the moment when it proves necessary to increase the heat capacity of the continuous transport device 9 , it suffices to bring the heating medium, which is at its operating temperature.

Es ist offensichtlich, daß es mit der beschriebenen Vorrichtung zum Beheizen möglich ist, wirksam und ohne Vergeudung die korrekte Trocknung der Klebematerialien zu bewirken. Außer­ dem ist es möglich, den gewünschten Zweck zu erreichen, ohne die kontinuierliche Transportvorrichtung 9 zu hohen Temperaturen auszusetzen, da beim Erhöhen der Wärmekapazität die gesamte Stärke der kontinuierlichen Transportvorrichtung 9 selbst betrof­ fen wird und nicht nur deren Oberflächenschicht.It is obvious that it is possible with the heating device described to effect the correct drying of the adhesive materials effectively and without wastage. In addition, it is possible to achieve the desired purpose without exposing the continuous transport device 9 to high temperatures, since when the heat capacity is increased, the entire thickness of the continuous transport device 9 itself is affected and not only the surface layer thereof.
