Description

Verfahren zur Herstellung von druckempfindlichen Selbstklebebändern mit rasterförmig angeordneten klebemassefreien Stellen, insbesondere Pflastern Die Herstellung von auf Druck ansprechenden Klebebändern, insbesondere von Pflastern, erfolgt in der Regel derart, daß die aus Gerüstsubstanz, Füllmitteln, Harzen und Weichmachern bestehenden kohäsiven Klebemassen mit oder ohne Lösungsmittel auf Trägerstoffe nach den üblichen Verfahren aufgebracht werden. Die Klebemassen lassen sich auch bei erhöhter Temperatur ohne Lösungsmittel aufstreichen, insbesondere dann, wenn thermoplastische Kunststoffe als Gerüstsubstanz verwendet werden.Process for the production of pressure-sensitive self-adhesive tapes with adhesive-free areas, in particular plasters, arranged in a grid the Production of pressure sensitive adhesive tapes, especially plasters, usually takes place in such a way that the structural substance, fillers, resins and Plasticizers existing cohesive adhesives with or without solvents on carrier materials can be applied according to the usual methods. The adhesives can also Brush on at elevated temperature without solvent, especially if thermoplastics can be used as a structural substance.

Es ist weiter bekannt, die Klebemassen nur auf abgegrenzte Flächen der Trägerstoffe aufzubringen, so daß in der Längs- oder Querrichtung Streifen oder Felder von bestrichenen oder unbestrichenen Stellen mit beliebigem Muster entstehen. It is also known that the adhesives only apply to delimited areas to apply the carrier materials, so that strips or in the longitudinal or transverse direction Fields of coated or uncoated areas with any pattern arise.

Zur Herstellung poröser Pflaster wird eine mit erhabenen Stellen oder mit punkt- oder strichförmigen Erhöhungen versehene Unterlage verwendet, über die die Stoffbahn an einer üblichen Streichvorrichtung unter Druck hindurchgeführt wird. Dabei wird die Klebemasse mit dem Stoff in die Vertiefungen gedrückt, während sie an den Erhöhungen weitgehend abgestrichen wird. Es können hierbei lösungsmittelhaltige oder lösungsmittelfreie erwärmte thermoplastische Klebemassen verarbeitet werden. For the production of porous plasters one with raised areas is used or underlay provided with point or line-shaped elevations, over which passed the fabric web under pressure on a conventional coating device will. The adhesive is pressed with the fabric into the depressions while it is largely struck off at the elevations. Solvent-based or solvent-free, heated thermoplastic adhesives are processed.

Die Strichstärke des Auftrages ist weitgehend von der Viskosität und der Temperatur der Klebemasse abhängig. Bei einigen bekannten Verfahren muß z. B. die Klebemasse durch besondere Vorrichtungen auf erhöhter Temperatur gehalten werden bzw. muß das Streichmesser beheizt werden. Die Strichstärke ist weiter abhängig von der Höhe der erhabenen Stellen auf der Unterlage, da sich der Stoff mit der Klebemasse nur in die Vertiefungen eindrücken kann. The line thickness of the order depends largely on the viscosity and the temperature of the adhesive. In some known methods, z. B. kept the adhesive at an elevated temperature by special devices will or the doctor blade must be heated. The line width is further dependent on the height of the raised areas on the surface, as there are the fabric with the adhesive can only press into the indentations.

Alle diese Nachteile und Schwierigkeiten werden vermieden bei Anwendung des vorgeschlagenen Verfahrens, nach dem poröse luft- und feuchtigkeitsdurchlässige Klebebänder und Pflaster hergestellt werden können. All of these drawbacks and difficulties are avoided in use of the proposed method, according to the porous air and moisture permeable Adhesive tapes and plasters can be made.

Erfindungsgemäß wird die Klebemasse des zunächst wie üblich gestrichenen oder kalanderten Klebebandes auf ihrer Oberfläche leicht erwärmt oder ohne Erwärmen mit Lösungsmitteln behandelt und dann über eine mit Erhebungen versehene Walze geführt, und zwar derart, daß diese Walze auf die mit Klebemasse versehene Seite des Bandes unter Druck einwirkt. Dies kann beispielsweise dadurch erfolgen, daß sich gegenüber dieser Walze eine zweite, elastische Walze befindet, die der mit Erhebungen versehenen Walze unter einstellbarem Druck aufliegt. Beim Durchführen des Klebebandes durch dieses Walzenpaar drücken sich die Erhebungen in die Klebemasse ein. Infolge des hierbei auf die Klebemasse ausgeübten Druckes, der Verringerung der Viskosität durch die Wärme oder das Lösungsmittel und infolge des kohäsiven VerhaI-tens der Klebemassen entstehen klebemassefreie Flächen auf dem Klebeband. An der Walze bleiben keine Rückstände. According to the invention, the adhesive is initially coated as usual or calendered adhesive tape on its surface slightly heated or without heating treated with solvents and then passed over a raised roller, in such a way that this roller is on the side of the tape provided with adhesive acts under pressure. This can be done, for example, by facing each other This roller is a second, elastic roller, the one provided with elevations Roller rests under adjustable pressure. When passing the tape through this pair of rollers press the elevations into the adhesive. As a result of the the pressure exerted here on the adhesive, the reduction in viscosity the heat or the solvent and as a result of the cohesive behavior of the adhesives Adhesive-free areas are created on the adhesive tape. None remain on the roller Residues.

Es war nicht vorauszusehen, daß durch das Einwirken einer Riffelwalze direkt auf die Klebeschicht des Selbstklebebandes ein gleichmäßiges Herstellen von klebstofffreien Stellen möglich sein würde. Vielmehr war zu vermuten, daß die Walze verschmieren und damit ein vollkommen ungleichmäßiges Freilegen des Klebemassenträgers an den gewünschten Stellen erfolgen würde. It was not foreseeable that by the action of a corrugated roller a uniform production of directly on the adhesive layer of the self-adhesive tape adhesive-free places would be possible. Rather, it was to be suspected that the roller smear and thus a completely uneven exposure of the adhesive carrier would be done in the desired places.

Die Erwärmung der Klebemassenoberfläche kann auch dadurch erfolgen, daß eine mit Erhebungen versehene beheizte Walze verwendet wird. Den gleichen Effekt erzielt man aber auch, wenn die Klebemasse vor dem Durchführen durch das Walzenpaar mit einem geeigneten Lösungsmittel leicht angelöst wird. The surface of the adhesive can also be heated by that a raised heated roller is used. The same effect but is also achieved if the adhesive is passed through the pair of rollers before it is passed through is easily dissolved with a suitable solvent.

Auf diese Weise lassen sich massefreie Muster, Punkte, Striche usw. auf beliebig hergestellten Selbstklebebändern und -pflastern in der Klebemasse erzeugen. In this way, floating patterns, points, lines, etc. on any self-adhesive tapes and plasters produced in the adhesive.

Die Luft- und Feuchtigkeits durchlässigkeit ist abhängig von der Zahl der klebemassefreien Stellen in der Klebeschicht und kann den Erfordernissen angepaßt werden. The air and moisture permeability depends on the Number of places in the adhesive layer that are free of adhesive and can meet the requirements be adjusted.

Bei den erfindungsgemäß hergestellten Pflastern überrascht, daß die Klebekraft kaum gemindert ist, obwohl sich die klebende Fläche durch die klebstofffreien Stellen verringert hat. In the case of the plasters produced according to the invention, it is surprising that the Adhesive strength is hardly diminished, although the adhesive surface is through the adhesive-free Has decreased.

Ein weiterer Vorteil der Erfindung ist, daß die Klebebänder erst in einem späteren Fabrikationsprozeß, nachdem sie in verschiedene Breiten geschnitten sind, mit einer porösen Klebeschicht versehen werden können. Another advantage of the invention is that the adhesive tapes only in a later manufacturing process after being cut into different widths can be provided with a porous adhesive layer.

Eine andere Ausführungsform besteht darin, daß an Stelle der mit Erhebungen ausgestatteten Walze eine solche mit rillenförmiger Oberfläche verwendet wird. Dadurch erhält man Streifen bzw. - wenn die Walze quer zur Längsrichtung der durchlaufenden Pflasterbahn hin- und herbewegt wird -wellenförmige Linien. Es ist auch möglich, mehrere Walzen hintereinander zu benutzen. Another embodiment is that instead of with Rolls equipped with elevations are used with a grooved surface will. This gives stripes or - if the roller is transverse to the longitudinal direction of the moving back and forth along the pavement track - wavy lines. It is also possible to use several rollers in a row.
