Definitions
- the present invention relates to a method and a device for the grid-like coating of web-like flexible flat structures with hot-melt adhesives in powder dot gravure and their production products.
- Coating methods have also become known, in which the grid-shaped coating is first applied to a carrier and this is then transferred from the carrier to the fabric to be actually coated.

- the width of the transfer carrier according to EP-0 219 378 A1 must be exactly matched to the sheet of fabric to be coated, and after the transfer process the transfer carrier must be wrapped and cleaned. Seams in the transfer carrier also always have a disruptive effect. If the carrier web is guided in a circle as an endless web, the wrapping is not necessary, but instead it is difficult to guide the web precisely and without distortion and to connect it smoothly at the connection point. Pinch folds can also occur.
- the invention is therefore based on the object of providing a method and a device for the grid-like coating of web-like flexible sheet-like structures with hot-melt adhesives in powder dot gravure, which can be carried out in a similar manner to the known coating methods without any appreciable additional outlay and the need to use web-like Avoids carrier tapes.
- the heating roller can be pressed against the engraving roller with a pressure of about 10 N / cm (1000 p / cm), while the further roller can be pressed against the heating roller with a pressure of about 0.5 N / cm (50 p / cm) should be pressed.
- the heating roller expediently has an anti-adhesive, rubber-like surface onto which the powder fillings of the engraving roller can be transferred by pressure.
- This surface can be formed by a roll cover, which has a thickness of 1 to 10 mm and can consist of a soft vulcanized silicone rubber coating.
- thermally conductive fillers such as carbon black, metal powder, metal oxide powder or the like. contain.
- the small proportions of about 0.1-2% fatty acid for example, contain palmitic, stearic or behenic acid in a very fine distribution.
- the transfer process should take place with a slight contact pressure which is generated by the further rotating roller which is assigned to the heating roller and between which and the heating roller the sheet is fed in and out. During this transfer process, the powder piles forming the coating flatten out. Excessive flattening can be prevented by appropriate selection of a low contact pressure on the roller.
- the hotmelt adhesive compositions suitable for the transfer coating are the same as are used in the known processes mentioned at the outset. Powders based on copolyesters, copolyamides and polyethylenes and mixtures thereof are suitable. The grits are also the same.
- the engraving and the coating can be in the form of dots, rods or meshes.
- the process conditions are practically the same as for the known powder dot gravure coatings mentioned above, with the engraving roller temperatures in the temperature range of approximately 30-90 ° C. and the heating roller temperatures in the temperature range of 160-240 ° C., depending on the type of hot-melt adhesive used.

- This funnel sits directly on the engraving roller 1 and is open at its bottom, so that the hot-melt adhesive powder 4 can flow into the recesses 2 therein when the surface of the engraving roller is rotated past.
- a squeegee plate attached to the funnel wall and tangential to the engraving roller ensures a smooth smear of the filled powder.
- the engraving roller is rotated in the direction of the arrow, so that the depressions 2 filled with hot-melt adhesive powder are moved towards a heated roller 5, which can be heated and has an anti-adhesive rubber coating 6.
- This heating roller 5, which rotates in the direction of the arrow shown in FIG. 1 in conformity with the engraving roller 1, is pressed relatively strongly onto the engraving roller, as a result of which the powder fillings located in the recesses 2 of the engraving roller are transferred to the rubber coating 6 of the heating roller and there as Put on the powder heap 7.
- the engraving roller 1 has on the surface, in particular of its depressions, a thin separating film covering for easy removal of the powder fillings from these depressions, which can consist of a material based on tetrafluoroethylene.
- the sheet 8 to be coated is fed in the form of a textile web 8, for example, and passed between the heating roller 5 and a further roller 9 associated therewith, which is arranged so that it presses the web 8 only slightly against the heating roller 5.
- the heating roller is brought to a temperature of about 160 to about 240 ° C, which leads to the fact that the powder piles 7 sitting on their coating 6 sinter together. Due to the slight pressure of the web 8 against the heating roller 5, these sintered piles of powder are transferred to the web, where they form a somewhat flattened grid-shaped coating as a result of this pressure.
- the grid-like coating can be punctiform, rod-shaped or linear.
- the arrangement and shape of the coating grid 10 on the sheet 8 is of course determined by the arrangement and shape of the cup-shaped depressions 2 on the surface of the engraving roller. Depending on the desired type of coating grid on the fabric, these depressions 2 on the surface of the engraving roller 1 must therefore be arranged and designed accordingly.
Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zum rasterförmigen Beschichten bahnförmiger flexibler Flächengebilde mit Schmelzklebern im Pulverpunkt-Tiefdruck und deren Fertigungsprodukte.The present invention relates to a method and a device for the grid-like coating of web-like flexible flat structures with hot-melt adhesives in powder dot gravure and their production products.
Es sind verschiedene Verfahren zum rasterförmigen, insbesondere punktrasterförmigen Beschichten von bahnförmigen flexiblen Flächengebilden wie Geweben, Gewirken, Webwirkwaren, Vliesen, Schaumstoffen, Kunstleder, Folien und anderen bekannt. Diese Verfahren arbeiten entweder nach dem Siebdruckverfahren mit Pasten oder nach dem Tiefdruckverfahren mit Pulvern. Dabei werden diese beiden Basisarbeitsweisen mit anderen Beschichtungsverfahren, beispielsweise mit einer Streubeschichtung oder einer Rollcoater-Beschichtung, kombiniert.Various methods for grid-like, in particular dot-grid, coating of flexible sheet-like structures such as woven fabrics, knitted fabrics, woven fabrics, nonwovens, foams, synthetic leather, foils and others are known. These processes work either with the screen printing process with pastes or with the gravure printing process with powders. These two basic working methods are combined with other coating processes, for example with a scatter coating or a roll coater coating.
Es sind auch Beschichtungsverfahren bekanntgeworden, bei denen die rasterförmige Beschichtung zunächst auf einen Träger aufgebracht und diese dann vom Träger auf das eigentlich zu beschichtende Flächengebilde übertragen wird. Aus DE-B-2 536 911 ist beispielsweise u.a. eine netzrasterförmige Pulverbeschichtung auf Silikonpapierträger und die Übertragung der Beschichtung auf Partien von Kleidungsstücken durch Aufbügeln des beschichteten Papiers und Abziehen des Trägers beschrieben worden. Eine punktrasterförmige Beschichtung auf einem klebstoffabweisenden Trägerpapier beschreibt weiterhin die DE-A-28 10 042, und auch aus der EP0 219 378 A1 ist eine derartige punktförmige Beschichtung durch Auftrag einer rasterförmigen Dispersionpaste auf einen antiadhäsiven Transferträger und das Übertragen der Klebstoffpunkte auf bahnenförmige Flächengebilde bekannt.Coating methods have also become known, in which the grid-shaped coating is first applied to a carrier and this is then transferred from the carrier to the fabric to be actually coated. DE-B-2 536 911, for example, includes one grid-shaped powder coating on silicone paper backing and the transfer of the coating to parts of clothing by ironing the coated paper and peeling off the backing have been described. DE-A-28 10 042 also describes a dot-matrix coating on an adhesive-repellent backing paper, and EP0 219 378 A1 also discloses such a dot-shaped coating by applying a grid-shaped dispersion paste to an anti-adhesive transfer carrier and transferring the adhesive dots to sheet-like fabrics.
Diese bekannten Transferbeschichtungen zeigen in manchen Fällen Vorteile dahingehend, daß die Beschichtungspunkte exakt ausgebildet und auf Flächengebilde übertragen werden können, die im Direktbeschichtungsverfahren nicht oder nur schwierig beschichtbar sind oder eine zu hohe Rückschlagneigung der Beschichtungspunkte durch den Beschichtungsträger hindurch beim Direktbeschichtungsvorgang zeigen. Allerdings sind die bisher bekanntgewordenen Arbeitsweisen umständlich, wenn sie für die Beschichtung bahnenförmiger Flächengebilde, wie beispielsweise bahnenförmiger Einlagestoffe, vorgesehen werden.These known transfer coatings in some cases show advantages in that the coating points can be formed precisely and transferred to fabrics which are not or only difficult to coat in the direct coating process or which show a high tendency of the coating points to kick back through the coating substrate during the direct coating process. However, the previously known working methods are cumbersome when they are provided for the coating of sheet-like flat structures, such as sheet-like interlining materials.
So muß der Transferträger nach der EP-0 219 378 A1 in der Breite exakt auf die zu beschichtende Flächengebildebahn abgestimmt sein und nach dem Transfervorgang muß der Transferträger umgewickelt und gereinigt werden. Auch Nahtstellen im Transferträger wirken sich immer störend aus. Sofern die Trägerbahn als Endlosbahn im Kreis geführt wird, entfällt zwar das Umwickeln, stattdessen ist es aber schwierig, die Bahn exakt und verzugsfrei zu führen und sie an der Verbindungsstelle stoßfrei zu verbinden. Auch Quetschfalten können entstehen.For example, the width of the transfer carrier according to EP-0 219 378 A1 must be exactly matched to the sheet of fabric to be coated, and after the transfer process the transfer carrier must be wrapped and cleaned. Seams in the transfer carrier also always have a disruptive effect. If the carrier web is guided in a circle as an endless web, the wrapping is not necessary, but instead it is difficult to guide the web precisely and without distortion and to connect it smoothly at the connection point. Pinch folds can also occur.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum rasterförmigen Beschichten bahnförmiger flexibler Flächengebilde mit Schmelzklebern im Pulverpunkt-Tiefdruck zu schaffen, das in ähnlicher Weise wie die bekannten Beschichtungsverfahren ohne nennenswerten zusätzlichen Aufwand ausgeführt werden kann und die Notwendigkeit der Benutzung von bahnenförmigen Trägerbändern vermeidet.The invention is therefore based on the object of providing a method and a device for the grid-like coating of web-like flexible sheet-like structures with hot-melt adhesives in powder dot gravure, which can be carried out in a similar manner to the known coating methods without any appreciable additional outlay and the need to use web-like Avoids carrier tapes.
Diese Aufgabe wird mit einem Verfahren und einer Vorrichtung der eingangs genannten Gattung gelöst, bei welchem erfindungsgemäß in die Vertiefungen einer Gravurwalze eingerakelte Schmelzkleber-Pulverfüllungen zunächst auf die Oberfläche einer direkt und kräftig an die Gravurwalze angepreßten Heizwalze überführt und von hier aus unter Anwendung einer weiteren, an die Heizwalze mit geringem Druck angepreßten rotierenden Walze auf das zwischen dieser und der Heizwalze hindurchgeführte Flächengebilde übertragen werden. Der Anpreßdruck dieser weiteren Walze über das Flächengebilde auf die Heizwalze soll also so bemessen werden, daß er wesentlich kleiner ist als der Anpreßdruck der Heizwalze an die Gravurwalze. So kann beispielsweise die Heizwalze mit einem Druck von etwa 10 N/cm (1000 p/cm) an die Gravurwalze angedrückt werden, während die weitere Walze über das Flächengebilde an die Heizwalze mit einem Druck von etwa 0,5 N/cm (50 p/cm) angepreßt werden sollte.This object is achieved with a method and a device of the type mentioned at the outset, in which, according to the invention, hot-melt adhesive powder fillings which have been knife-coated into the recesses of an engraving roll are first transferred to the surface of a heating roll pressed directly and strongly onto the engraving roll and from here using a further, to the heating roller, which is pressed under low pressure, can be transferred to the fabric passed between it and the heating roller. The contact pressure of this further roller over the fabric on the heating roller should therefore be dimensioned such that it is substantially less than the contact pressure of the heating roller on the engraving roller. For example, the heating roller can be pressed against the engraving roller with a pressure of about 10 N / cm (1000 p / cm), while the further roller can be pressed against the heating roller with a pressure of about 0.5 N / cm (50 p / cm) should be pressed.
Zweckmäßig hat die Heizwalze eine antiadhäsive gummiartige Oberfläche, auf welche die Pulverfüllungen der Gravurwalze durch Andruck überführbar sind. Diese Oberfläche kann von einem Walzenüberzug gebildet sein, der eine Dicke von 1 bis 10 mm haben und aus einem weichen ausvulkanisierten Silikongummibelag bestehen kann. Um einen guten Wärmedurchgang durch den Belag zu erhalten, kann er wärmeleitfähige Füllstoffe, wie Ruß, Metallpulver, Metalloxidpulver od.dgl. enthalten.The heating roller expediently has an anti-adhesive, rubber-like surface onto which the powder fillings of the engraving roller can be transferred by pressure. This surface can be formed by a roll cover, which has a thickness of 1 to 10 mm and can consist of a soft vulcanized silicone rubber coating. In order to obtain good heat transfer through the covering, it can thermally conductive fillers such as carbon black, metal powder, metal oxide powder or the like. contain.
Es ist auch zweckmäßig, die Gravurwalze mit einem eingebrannten dünnen Trennfilm auf der Basis von Tetrafluorethylen zu versehen, um die Übertragung von Pulverfüllungen auf den Silikongummibelag zu begünstigen.It is also expedient to provide the engraved roller with a baked thin release film based on tetrafluoroethylene in order to favor the transfer of powder fillings to the silicone rubber covering.
Um den anschließenden Transfervorgang der aus den Vertiefungen der Gravurwalze herausgelösten und auf der Oberfläche der Heizwalze zusammensinternden Pulverhäufchen auf das vorzugsweise bahnförmige Flächengebilde völlig reibungslos ablaufen zu lassen, ist es zweckdienlich, Schmelzkleberpulver zu verwenden, die geringe Anteile von etwa 0,1-2 % Fettsäure, beispielsweise Palmitin-, Stearin- oder Behensäure in feinster Verteilung enthalten.In order to allow the subsequent transfer process of the powder piles loosened from the recesses of the engraving roller and sintering together on the surface of the heating roller to run smoothly onto the preferably sheet-like fabric, it is expedient to use hot-melt adhesive powder, the small proportions of about 0.1-2% fatty acid , for example, contain palmitic, stearic or behenic acid in a very fine distribution.
Der Übertragungsvorgang soll mit leichtem Anpreßdruck erfolgen, der durch die weitere rotierende Walze erzeugt wird, die der Heizwalze zugeordnet ist und zwischen welcher und der Heizwalze das Flächengebilde hindurch zu- und abgeführt wird. Bei diesem Transfervorgang findet eine Abflachung der die Beschichtung bildenden Pulverhäufchen statt. Eine zu starke Abflachung kann durch entsprechende Wahl eines niederen Anpreßdruckes der Walze verhindert werden.The transfer process should take place with a slight contact pressure which is generated by the further rotating roller which is assigned to the heating roller and between which and the heating roller the sheet is fed in and out. During this transfer process, the powder piles forming the coating flatten out. Excessive flattening can be prevented by appropriate selection of a low contact pressure on the roller.
Die für die Transferbeschichtung geeigneten Schmelzklebermassen sind die gleichen, wie sie bei den eingangs erwähnten bekannten Verfahren Anwendung finden. Geeignet sind Pulver auf Basis von Copolyestern, Copolyamiden und Polyethylenen und deren Mischungen. Auch die Körnungen sind die gleichen.The hotmelt adhesive compositions suitable for the transfer coating are the same as are used in the known processes mentioned at the outset. Powders based on copolyesters, copolyamides and polyethylenes and mixtures thereof are suitable. The grits are also the same.
Die Gravur und die Beschichtung kann in Punkt-, Stäbchen- oder Netzform ausgebildet sein.The engraving and the coating can be in the form of dots, rods or meshes.
Die Verfahrensbedingungen sind praktisch die gleichen wie bei den vorerwähnten bekannten Pulverpunkt-Tiefdruckbeschichtungen, wobei die Gravurwalzentemperaturen im Temperaturbereich von etwa 30-90° C und die Heizwalzentemperaturen im Temperaturbereich von 160-240° C je nach Art der verwendeten Schmelzklebertype liegen sollten.The process conditions are practically the same as for the known powder dot gravure coatings mentioned above, with the engraving roller temperatures in the temperature range of approximately 30-90 ° C. and the heating roller temperatures in the temperature range of 160-240 ° C., depending on the type of hot-melt adhesive used.
Mit dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Vorrichtung läßt sich ein breites Sortiment von Flächengebilden beschichten, auch solche, die aufgrund einer haarigen oder zu offenmaschigen Konstruktion im Direktbeschichtungsverfahren nicht oder nur schiwerig beschichtbar sind. Es lassen sich beschichtete Einlagestoffe auf Basis von Geweben, Gewirken, Webwirkwaren, Vliesen, Wirkvliesen, Webwirkvliesen herstellen. Auch beschichtete Kunstleder, Folien, Papiere, Schaumstoffe können problemlos erzeugt werden.With the method and the device according to the invention, a wide assortment of fabrics can be coated, including those that are not or only difficult to coat due to a hairy or too open-mesh construction in the direct coating method. Coated interlining fabrics based on woven fabrics, knitted fabrics, knitted fabrics, nonwovens, knitted nonwovens and woven knitted fabrics can be produced. Coated synthetic leather, foils, papers, foams can also be produced without any problems.

Die in Fig. 1 gezeigte Vorrichtung besitzt oberhalb der Gravurwalze 1, die an ihrer zylindrischen Oberfläche mit napfförmigen Vertiefungen 2 ausgestattet ist, und um ihre Achse drehbar ist, einen trichterförmigen Vorratsbehälter 3 für pulverförmige Schmelzkleber 4. Dieser Trichter sitzt unmittelbar auf der Gravurwalze 1 und ist an seinem Boden geöffnet, so daß das Schmelzkleberpulver 4 beim Vorbeidrehen der Oberfläche der Gravurwalze in die darin befindlichen Vertiefungen 2 einströmen kann. Ein an der Trichterwandung befestigtes und an der Gravurwalze tangential anliegendes Rakelblech sorgt für einen glatten Abstrich des eingefüllten Pulvers. Die Gravurwalze wird in Richtung des Pfeiles gedreht, so daß die mit Schmelzkleberpulver gefüllten Vertiefungen 2 zu einer beheizten Walze 5 hinbewegt werden, die beheizbar ist und einen antiadhäsiven Gummiüberzug 6 hat. Diese Heizwalze 5, die in Richtung des in Fig. 1 gezeigten Pfeiles konform mit der Gravurwalze 1 umläuft, wird relativ kräftig an die Gravurwalze angedrückt, wodurch die in den Vertiefungen 2 der Gravurwalze befindlichen Pulverfüllungen auf den Gummiüberzug 6 der Heizwalze übertragen werden und dort als Pulverhäufchen 7 aufsitzen.The device shown in Fig. 1 has above the engraving roller 1, which is provided on its cylindrical surface with cup-shaped depressions 2 and is rotatable about its axis, a funnel-shaped storage container 3 for powdered hot melt adhesive 4. This funnel sits directly on the engraving roller 1 and is open at its bottom, so that the hot-melt adhesive powder 4 can flow into the recesses 2 therein when the surface of the engraving roller is rotated past. A squeegee plate attached to the funnel wall and tangential to the engraving roller ensures a smooth smear of the filled powder. The engraving roller is rotated in the direction of the arrow, so that the depressions 2 filled with hot-melt adhesive powder are moved towards a heated roller 5, which can be heated and has an anti-adhesive rubber coating 6. This heating roller 5, which rotates in the direction of the arrow shown in FIG. 1 in conformity with the engraving roller 1, is pressed relatively strongly onto the engraving roller, as a result of which the powder fillings located in the recesses 2 of the engraving roller are transferred to the rubber coating 6 of the heating roller and there as Put on the powder heap 7.
Die Gravurwalze 1 hat an der Oberfläche insbesondere ihrer Vertiefungen einen dünnen Trennfilmbelag zum leichten Herauslösen der Pulverfüllungen aus diesen Vertiefungen, der aus einem Material auf der Basis von Tetrafluorethylen bestehen kann.The engraving roller 1 has on the surface, in particular of its depressions, a thin separating film covering for easy removal of the powder fillings from these depressions, which can consist of a material based on tetrafluoroethylene.
An der der Gravurwalze gegenüberliegenden Seite der Heizwalze 5 wird das zu beschichtende Flächengebilde 8 in Form einer z.B. textilen Warenbahn 8 zugeführt und zwischen der Heizwalze 5 und einer weiteren, dieser zugeordneten Walze 9 hindurchgeführt, die so angeordnet ist, daß sie die Warenbahn 8 nur leicht gegen die Heizwalze 5 drückt. Die Heizwalze wird auf eine Temperatur von etwa 160 bis etwa 240° C gebracht, was dazu führt, daß die auf ihrem Überzug 6 sitzenden Pulverhäufchen 7 zusammensintern. Durch den geringen Andruck der Warenbahn 8 gegen die Heizwalze 5 werden diese zusammengesinterten Pulverhäufchen auf die Warenbahn übertragen, wo sie infolge dieses Andrucks eine etwas plattgedrückte rasterförmige Beschichtung bilden. Die rasterförmige Beschichtung kann punkt-, stäbchen- oder linienförmig sein. Die Anordnung und Gestalt des Beschichtungsrasters 10 auf dem Flächengebilde 8 wird natürlich durch die Anordnung und die Gestalt der napfförmigen Vertiefungen 2 an der Oberfläche der Gravurwalze bestimmt. Je nach der gewünschten Art des Beschichtungsrasters auf dem Flächengebilde müssen daher diese Vertiefungen 2 auf der Oberfläche der Gravurwalze 1 entsprechend angeordnet und gestaltet sein.On the side of the heating roller 5 opposite the engraving roller, the
