Description

Verfahren und Vorrichtung zum kontinuierlichen festhaftenden Beschichten der Oberfläche von aus thermoplastischem Kunststoffschaum bestehenden Bahnen mit Bahnen aus anderen Werkstoffen Die Erfindung betrifft ein Verfahren zum Beschichten der Oberfläche von aus thermoplastischem Kunststoffschaum bestehenden Bahnen mit Bahnen aus anderen Werkstoffen, z. B. PVC-Folien, textilen Geweben oder Gewirken, Papier, Pappe oder Leder sowie eine Vorrichtung zur Ausübung dieses Verfahrens.Method and device for continuous adhesive coating the surface of thermoplastic foam sheets with Sheets of Other Materials The invention relates to a method of coating the surface of thermoplastic foam sheets with Sheets made of other materials, e.g. B. PVC films, textile fabrics or knitted fabrics, Paper, cardboard or leather and a device for performing this process.

Zur Beschichtung der Oberfläche von aus thermoplastischem Kunststoffschaum bestehenden Bahnen mit Bahnen aus anderen Werkstoffen ist es bekannt, die zu beschichtende Oberfläche der aus Kunststoffschaum bestehenden Bahn durch Wärmebehandlung zu plastifizieren und anschließend die aus dem anderen Werkstoff bestehende Auflagebahn fest gegen die plastifizierte Oberfläche der Schaumstoffbahn zu drücken. Besteht auch die Auflagebahn aus einem thermoplastischen Kunststoff oder enthält sie einen solchen, so kann statt der Plastifizierung der Oberfläche der Schaumstoffbahn eine solche der Oberfläche der Auflagebahn vorgenommen und diese mit ihrer plastifizierten Fläche gegen die Schaumstoffbahn gepreßt werden. Die Plastifizierung der Oberflächenschicht der Schaumstoffbahn oder der Auflagebahn kann durch Wärmestrahler, z. B. elektrisch oder mit Gas betriebene Ultrarotstrahler, erfolgen, aber auch durch direkte Flammeneinwirkung (offene Gasflamme) oder durch beheizte Walzen bzw. Platten. For coating the surface of thermoplastic plastic foam existing webs with webs made of other materials, it is known to be coated To plasticize the surface of the plastic foam sheet by heat treatment and then firmly against the support sheet consisting of the other material to press the plasticized surface of the foam sheet. There is also the runway made of a thermoplastic material or if it contains such a material, it can take place the plasticization of the surface of the foam sheet is the same as the surface made of the support web and this with its plasticized surface against the Foam sheet are pressed. The plasticization of the surface layer of the foam sheet or the support web can be heated by radiant heaters, e.g. B. electrically or gas powered Infrared emitters, but also by direct flame exposure (open gas flame) or by heated rollers or plates.

Um eine feste Verbindung der Bahnen miteinander zu bewirken, ist ferner vorgeschlagen worden, das Aufeinanderdrücken der mindestens auf einer der beiden einander zugekehrten Flächen plastifizierten Bahnen durch Kalanderwalzen zu bewirken, die auf einer das sofortige Erstarren des plastifizierten Kunststoffes herbeiführenden Temperatur gehalten werden. In order to create a firm connection between the webs, is It has also been proposed to press the at least one of the both facing surfaces plasticized webs by calender rolls to cause the immediate solidification of the plasticized plastic on a causing temperature to be maintained.

Hierbei hat sich gezeigt, daß in manchen Fällen die zur festen Verbindung der Bahnen zur Verfügung stehende Zeit zu kurz ist, um ein hinreichend gutes Eindringen der plastifizierten Masse der Schaumstoffbahn in die Auflagebahn und damit die feste Verankerung der Bahnen zu ermöglichen.It has been shown that in some cases the fixed connection the time available for the webs is too short for a sufficiently good penetration the plasticized mass of the foam sheet in the support sheet and thus the solid To enable anchoring of the webs.

Die Erfindung bezweckt, insbesondere diesen Nachteil zu beseitigen und sieht vor, daß nach dem Plastifizieren der Oberfläche der Schaumstoffbahn laufend ein Teil der plastifizierten Masse von dieser Bahn abgetragen und auf die Oberfläche der vorher erwärmten Auflagebahn übertragen wird und anschließend die beiden Bahnen, mit ihren klebrigen Oberflächen einander zugekehrt, in einem Kalanderwalzenspalt bei einer das sofortige Erstarren des plastifizierten Kunststoffes herbeiführenden Temperatur aufeinandergedrückt werden. Hierbei kann der von der Oberfläche der Schaumstoffbahn abgetragene Teil der plastifizierten Masse während seiner Ubertragung auf die Oberfläche der Auflagebahn auf der Plastifizierungstemperatur gehalten oder aber auch einer zusätzlichen Erwärmung auf eine höhere Temperatur unterworfen werden, was insbesondere dann wünschenswert ist, wenn zur Verankerung der plastifizierten Masse mit der Auflagebahn eine geringere Konsistenz dieser Masse erforderlich ist. The invention aims in particular to eliminate this disadvantage and provides that after the plasticizing of the surface of the foam web continuously a part of the plasticized mass is removed from this web and onto the surface the previously heated support web is transferred and then the two webs, with their sticky surfaces facing each other in a calender nip in the case of one causing the immediate solidification of the plasticized plastic Temperature are pressed against each other. Here, the from the surface of the foam sheet worn Part of the plasticized mass during its transfer to the surface the support web is kept at the plasticizing temperature or one additional heating to a higher temperature are subjected to what in particular It is then desirable if for anchoring the plasticized mass with the support sheet a lower consistency of this mass is required.

Zur Ausübung dieses Verfahrens sieht die Erfindung eine Vorrichtung vor, bei der vor den Spalt zweier Kalanderwalzen, die auf einer das Erstarren der plastifizierten Masse der Schaumstoffbahn bewirkende Temperatur gehalten werden, und zwar im Zulauf der miteinander zu verbindenden Bahnen zu dem Kalanderwalzenspalt, eine an sich zum Anschmelzen der Oberfläche einer Schaumstoffbahn bekannte beheizbare Trommel derart angeordnet ist, daß ihr Mantel die dem Kalanderwalzenspalt zugeführten Bahnen an diametral entgegengesetzten Stellen berührt und beim Trommelumlauf einen Teil der plastifizierten Masse der Oberflächenschicht der Schaumstoffbahn auf die mit dieser zu verbindenden Bahn überträgt. The invention provides an apparatus for carrying out this method before, at the front of the nip of two calender rolls, which on one of the solidification of the plasticized mass of the foam sheet causing temperature are maintained, namely in the inlet of the webs to be connected to the calender nip, a heatable one known per se for melting the surface of a foam sheet Drum is arranged such that its shell is fed to the calender nip Touches tracks at diametrically opposite points and one when the drum rotates Part of the plasticized mass of the surface layer of the foam sheet on the transmits with this web to be connected.

Hierbei können neben dem Zulauf der Schaumstoffbahn zu der beheizten Trommel zusätzlich zu dieser auf die zu plastifizierende Oberfläche dieser Bahn einwirkende, das Plastifizieren bewirkende Wärmequellen angeordnet sein; es kann aber auch die dem Kalanderwalzenspalt vorgeschaltete Trommel allein zum Plastifizieren der Oberfläche der Schaumstoflbahn Verwendung finden, wobei diese durch Führungen mit einem zur Plastifizierung ausreichenden Teil des Trommelumfanges in Berührung gehalten wird. Here, in addition to the inlet of the foam sheet to the heated Drum in addition to this on the surface to be plasticized of this web acting, the plasticizing effecting heat sources be arranged; it can but also the drum upstream of the calender nip for plasticizing alone the surface of the Foam web find use, this through guides with a sufficient part of the drum circumference for plasticization is kept in touch.

Die im Zulauf der Schaumstoffbahn zu der beheizten Trommel angeordneten Führungen sind zwecks Einstellung der Strecke, auf der die Schaumstoffbahn mit dem Trommelumfang in Berührung ist, vorzugsweise verstellbar. Ferner empfiehlt es sich, auch im Zulauf der Auflagebahn zu der beheizten Trommel verstellbare Führungen anzuordnen, die der Einstellung der Strecke dienen, auf der die Auflagebahn mit dem Trommelumfang in Berührung kommt. Those arranged in the inlet of the foam sheet to the heated drum Guides are for the purpose of setting the route on which the foam sheet with the Drum circumference is in contact, preferably adjustable. It is also recommended that also to arrange adjustable guides in the feed path to the heated drum, which are used to set the distance on which the support track with the drum circumference comes into contact.

Soll die auf die Auflagebahn zu übertragende plastifizierte Masse noch zusätzlich erwärmt werden, so empfiehlt es sich, dem Kalanderwalzenspalt eine beheizte Trommel vorzuschalten, deren Mantel nur von der Schaumstoflbahn berührt wird und auf seiner dieser Berührungsstelle abgewandten Seite mit dem Mantel einer parallelachsig angeordneten zusätzlichen, der Führung der Auflagebahn dienenden Trommel in Berührung steht, wobei diese ebenfalls beheizbar ist. Should the plasticized mass to be transferred to the support web are additionally heated, it is advisable to add a upstream heated drum, the jacket of which only touches the foam sheet and on its side facing away from this point of contact with the coat of a additional parallel axes that serve to guide the support track Drum is in contact, which can also be heated.

In der Zeichnung ist das Verfahren gemäß der Erfindung an Hand zweier. Ausführungsbeispiele einer zu seiner Durchführung dienenden Vorrichtung schematisch veranschaulicht. In the drawing, the method according to the invention is illustrated by two. Exemplary embodiments of a device used to carry it out are shown schematically illustrated.

Bei der in Fig. 1 dargestellten Ausführungsform ist einem durch die Walzen 11 und 12 gebildeten Kalanderwalzenspalt eine beheizte Trommel 10 vorgeschaltet, die sich in der Pfeilrichtung y dreht. Eine Schaumstoflbahn A wird in der Pfeilrichtung x über die beheizte Trommel 10 dem Kalanderwalzenspalt 11, 12 zugeführt, während eine Auflagebahn B in der gleichen Pfeilrichtung x über die beheizte Trommel 10 ebenfalls dem Kalanderwalzenspalt zugeleitet wird. Die Auf]agebahnB besteht beispielsweise aus einem textilen Gewebe, kann aber auch aus Papier, Pappe, einer Kunststoffolie, Kork, Leder oder Linoleum bestehen. In the embodiment shown in Fig. 1 is one by the Rolls 11 and 12 formed calender nip a heated drum 10 upstream, which rotates in the direction of the arrow y. A foam sheet A is made in the direction of the arrow x supplied to the calender nip 11, 12 via the heated drum 10, while a support web B in the same arrow direction x over the heated drum 10 is also fed to the calender nip. The Auf] agebahnB exists for example made of a textile fabric, but can also be made of paper, cardboard, a plastic film, Are made of cork, leather or linoleum.

In dem dargestellten Ausführungsbeispiel dient die beheizte Trommel 10 selbst zum Plastifizieren einer Oberflächenschicht der Schaumstoflbahn A und wird daher auf einer entsprechenden Temperatur (300 bis 5000 C) gehalten. Die Höhe der Temperatur hängt ab von der Umlaufgeschwindigkeit der Trommel 10, der Vorschubgeschwindigkeit der Schaumstoffbahn und dem Ausmaß der Berührung zwischen der Trommel und der Schaumstoffbahn. Bei Schaumstofibahnen auf Polyurethan-Basis empfiehlt sich die Einhaltung einer Temperatur von 400 bis 4500 C. Vor der beheizten Trommel 10 sind im Zulauf der Schaumstoffbahn A zwei Führungswalzen G und 8 angeordnet, die entsprechend der Dicke der Schaumstoffbahn A gegeneinander verstellbar sind, darüber hinaus aber auch so verstellt werden können, daß die Strecke, auf der die Schaumstoffbahn A mit dem Umfang der Trommel 10 in Berührung kommt, eingestellt werden kann. In the illustrated embodiment, the heated drum is used 10 itself for plasticizing a surface layer of the foam sheet A and is therefore kept at an appropriate temperature (300 to 5000 C). The height the temperature depends on the speed of rotation of the drum 10, the feed speed the foam sheet and the amount of contact between the drum and the foam sheet. In the case of foam sheets based on polyurethane, it is advisable to comply with a Temperature from 400 to 4500 C. Before the heated drum 10 are in the inlet of the foam web A two guide rollers G and 8 are arranged, which correspond to the thickness of the foam sheet A are mutually adjustable, but can also be adjusted so that that the distance on which the foam sheet A with the circumference of the drum 10 in Contact comes, can be adjusted.

Obwohl es vorteilhaft ist, die Plastifizierung einer Oberflächenschicht der Schaumstoffbahn A durch die Trommel 10 selbst herbeizuführen, kann zwischen der Walze 6 und der Trommel 10 eine besondere Wärmequelle angeordnet werden, die durch Wärmestrahlung oder durch direkte Flammeneinwirkung die Schaumstofibahn in einem jeweils gewünschten Ausmaß anschmilzt. Als solche Wärmequellen kommen insbesondere elektrisch oder mit Gas betriebene Infrarotstrahler oder die Oberfläche der Scfraümstoffbahn bestreichende Gasflammen in Betracht. Although it is advantageous to plasticize a surface layer to bring about the foam web A through the drum 10 itself, can between the roller 6 and the drum 10 a special heat source are arranged, the the foam sheet in melts to the desired extent. As such heat sources come in particular electric or gas operated infrared emitters or the surface of the fabric sheet brushing gas flames into consideration.

Die Hauptaufgabe der Trommel 10 besteht darin, einen Teil der durch sie selbst oder durch eine vorgeschaltete Wärmequelle plastifizierten Masse der Schaumstoffbahn abzutragen und auf die ebenfalls in Berührung mit der Trommel laufende Auflagebahn B zu übertragen. Einen Teil der besagten Masse der Schaumstoffbahn verbleibt also als klebrige Schicht A1 auf der Schaumstoffbahn A, während ein anderer Teil als Schicht A2 von der Trommel mitgenommen und auf die Auflagebahn B übertragen wird. Auf dem Weg von der Trommel 10 zu dem Kalanderwalzenspalt 11, 12 bildet dieser übertragende Teil der plastifizierten Masse auf der Auflagebahn B eine Auflageschicht Bl, die, da die SchichtA2 auf der Trommel 10 laufend erhitzt worden ist, eine hinreichend flüssige Konsistenz hat, um beispielsweise in einem gewissen Ausmaß in die Poren eines Gewebes, aus dem die Aufiagebabn besteht, eindringen und dennoch auf der Oberfläche der Bahn B eine klebrige Schicht bilden zu können. The main task of the drum 10 is to move part of the through they themselves or mass of plasticized by an upstream heat source To remove foam web and to also run in contact with the drum Transfer runway B. Part of the said mass of the foam sheet remains so as a sticky layer A1 on the foam sheet A, while another part taken from the drum as layer A2 and transferred to the support web B. will. On the way from the drum 10 to the calender nip 11, 12 this forms Transferring part of the plasticized mass on the support web B a support layer B1, which, since the layer A2 has been continuously heated on the drum 10, is a sufficient one liquid consistency has, for example, to some extent into the pores of a tissue, of which the Aufiagebabn consists, penetrate and still on the surface the web B to be able to form a sticky layer.

Im Zulauf der Auflagebahn B zu der Trommel 10 liegt eine Walze 14, die derart höhenverstellbar ist (14'), daß die Strecke, auf der die Bahn B mit dem Umfang der Trommel 10 in Berührung kommt, eingestellt werden kann. Auf diese Weise ist man in der Lage, die Dauer der Wärmeeinwirkung der Trommel 10 auf die BahnB zu verändern, dieser Bahn also entweder die gewünschte Temperatur zu geben oder aber sie sogar auf ihrer der Trommel zugekehrten Fläche anzuschmelzen, falls sie aus einem thermoplastischen Kunststoff besteht, und auf diese angeschmolzene Fläche die Schicht B1 aufzulegen. In the inlet of the support web B to the drum 10 is a roller 14, which is adjustable in height (14 ') that the route on which the web B with the Perimeter of the drum 10 comes into contact, can be adjusted. In this way one is able to determine the duration of the thermal action of the drum 10 on the webB to change, so either give this path the desired temperature or but even to melt them on their surface facing the drum, if they consists of a thermoplastic material, and on this melted surface to apply layer B1.

Im Kalanderwalzenspalt 11, 12 kommen die aus dem gleichen Werkstoff bestehenden Schichten Ar und Bl miteinander in Berührung, so daß beim Erstarren dieser Schichten unter dem Einfluß der geringen Temperatur der Kalanderwalzen eine wirklich feste Verbindung der Schaumstoffbahn A mit der Auflagebahn B zustande kommt. In the calender nip 11, 12 they come from the same material existing layers Ar and Bl in contact with each other, so that when solidifying of these layers under the influence of the low temperature of the calender rolls really firm connection of the foam sheet A with the support sheet B comes about.

Bei dem in Fig.2 dargestellten Ausführungsbeispiel kommt nur die durch die Walzen 6 a und 8 a geführte Schaumstoffbahn A mit dem Umfang der beheizten Trommel 10 a in Berührung und läuft anschließend in den Spalt der Kalanderwalzen 11 a, 12 a ein. Die durch die beheizte TrommellOa plastifizierte Schicht der Schaumstoffbahn A verbleibt teilweise als klebrige Schicht A1 auf der Schaumstoffbahn, während ein anderer Teil A2 von der Trommel 10a mitgenommen und an den Umfang einer parallelachsig zu der Trommel 10 a angeordneten und mit dieser in Berührung stehenden Trommel 16 übertragen wird, an der die von der Walze 14 a geführte Auflagebahn B anliegt. Die Trommel 16 gibt die auf ihr sitzende Schicht A2 als klebrige Schicht B1 an die Auflagebahn B ab, und im Spalt zwischen den Walzen 11 a, 12 a verbinden sich die Schichten A1 und B1 fest miteinander. Die Trommel 16 kann zur stärkeren Verflüssigung der auf ihr liegenden Schicht A2 auf eine höhere Temperatur erhitzt werden als die TrommellOa. Der Abstand zwischen der Trommel lLOa und 16 wird vorzugsweise einstellbar gemacht. In the embodiment shown in Figure 2 only comes through the rollers 6 a and 8 a guided foam sheet A with the circumference of the heated Drum 10 a in contact and then runs into the gap of the calender rolls 11 a, 12 a a. The layer of the foam sheet plasticized by the heated drum pad A partially remains as a sticky layer A1 on the foam sheet, while a other part A2 taken from the drum 10a and axially parallel to the circumference of a drum 16 arranged in relation to drum 10 a and in contact with it is transmitted, on which the support web B guided by the roller 14 a rests. the Drum 16 gives the layer A2 sitting on it as a sticky layer B1 to the support web B from, and in the gap between the rollers 11 a, 12 a, the layers A1 connect and B1 firmly together. The drum 16 can be used to liquefy the stronger their lying layer A2 can be heated to a higher temperature than the drum Oa. The distance between the drum 10a and 16 is preferably made adjustable.
