Description

Die Erfindung bezieht sich auf eine Bügelwalze, insbesondere für den Wäschereibetrieb, die in einer Muldenmangel unter Wärmezufuhr umläuft, wobei die Bügel- oder Mangelwalze aus einer hohlen Stahltrommel mit siebartig gelochtem Material, einer in radialer Richtung eigenfedernden und gasdurchlässigen Polsterlage und einem Überzug aus Textil, z.B. Moltontuch, Nadelfilz od.dgl., gebildet ist, und wobei die Polsterlage aus elastischem Silikongummi besteht, der Polsterstreifen verteilte Lochungen aufweist und die Polsterstreifen durch schraubenlinienförmiges Wickeln auf dem Trommelmantel aufgebracht sind.The invention relates to an ironing roller, in particular for the laundry business, which rotates in a trough lack with the supply of heat, the ironing or ironing roller consisting of a hollow steel drum with sieve-like perforated material, a gas-permeable cushion layer which is self-springing in the radial direction and a textile covering, e.g. Molton cloth, needle felt or the like. Is formed, and wherein the padding layer consists of elastic silicone rubber, the padding strips have distributed perforations and the padding strips are applied by helical winding on the drum shell.

Die elastischen Unterlagen für Heißmangel-oder Bügelwalzen sind durch die Wärmeeinwirkung und durch die mechanische Beanspruchung verhältnismäßig großem Verschleiß unterworfen, wobei sich die Anforderungen an die elastischen Unterlagen, insbesondere auf die Wärmebeständigkeit, eine gleichmäßige Elastizität und auch auf eine dauerhafte Haltbarkeit beziehen. Es ist bereits bekannt, als geeigneten Werkstoff für die elastische Polsterlage Silikonkautschuk zu verwenden und auch die Polsterlage mit Perforationen zu versehen, die in annähernd radialer Richtung angeordnet sind. Die Ausbildung der Polsterlage in bezug auf die Abführung des Wasserdampfes bzw. des Kondensates in Verbindung mit der Haltbarkeit ist noch nicht zufriedenstellend gelöst worden.The elastic underlays for hot ironing or ironing rolls are subject to relatively great wear due to the action of heat and mechanical stress, the requirements for the elastic underlays relating in particular to heat resistance, uniform elasticity and also to long-lasting durability. It is already known to use silicone rubber as a suitable material for the elastic cushion layer and also to provide the cushion layer with perforations which are arranged in an approximately radial direction. The formation of the cushion layer in relation to the removal of the water vapor or the condensate in connection with the durability has not yet been satisfactorily resolved.

Die FR-PS 2 467 256 beschreibt eine mit einem Muldenmantel zusammenarbeitende Bügelwalze, bei der die Polsterlage in radialer Richtung mehrteilig ausgebildet ist. Die Bügelwalze setzt sich aus einem Metallzylinder, dessen Oberfläche perforiert ist, einer Elastomerschicht aus Silikongummi und einem Überzug aus Molton oder sonstigem Gewebe zusammen. Die Elastomerschicht ist mit Lochungen versehen, die mit der äußeren Garnitur in Verbindung treten sollen, um eine Trocknung durch Heraustreten des Dampfes der Wäsche in den Zwischenraum der Maschine zu realisieren. Über die Tiefe der Lochungen ist keine Aussage gemacht. Nach dem gesamten Aufbau der Polsterlage zu schließen, kommt es bei der Polsterlage offenbar darauf an, daß eine Entwässerung der Elastomerlage nach außen hin erfolgt und nicht nach innen. Dies ergibt sich auch aus dem Umstand, daß an der Außenseite der Elastomerlage längs verlaufende Nuten angeordnet sind, die mit der Garnitur in Berührung kommen. Die Silikongummischicht beträgt in der Dicke nur einen Teil der Gesamtdicke der Polsterlage, die noch eine Grundschicht von unbekannter Zusammensetzung aufweist. Bei einem solchen Aufbau der Polsterlage ist keine genügende Entwässerung der Polsterschicht erkennbar. Es ist auch keine Vorsorge dafür getroffen, daß die Lochungen bei der verhältnismäßig dünnen Schicht aus Silikongummi durch die hohe Pressung nicht zusammengedrückt werden.FR-PS 2 467 256 describes an ironing roller which cooperates with a trough jacket and in which the cushion layer is made of several parts in the radial direction. The ironing roller consists of a metal cylinder, the surface of which is perforated, an elastomer layer made of silicone rubber and a coating of molton or other fabric. The elastomer layer is provided with perforations which are intended to connect to the outer clothing in order to achieve drying by the steam coming out of the laundry into the intermediate space of the machine. No statement is made about the depth of the perforations. After the entire structure of the cushion layer has been closed, it is obviously important for the cushion layer that the elastomer layer is drained to the outside and not to the inside. This also results from the fact that longitudinal grooves are arranged on the outside of the elastomer layer, which come into contact with the clothing. The thickness of the silicone rubber layer is only a part of the total thickness of the cushion layer, which still has a base layer of unknown composition. With such a structure of the cushion layer, no sufficient drainage of the cushion layer can be seen. There is also no provision that the perforations in the relatively thin layer of silicone rubber are not compressed by the high pressure.

Die AT-PS 229 259 befaßt sich mit einem heizbaren Kalander zur Verfestigung von thermoplastischen Fasern enthaltenden Vliesen. Bei einem Kalander geht es darum, daß die äußere Schicht auf einem zylindrischen Metallmantel sehr massiv oder als Rohr unperforiert aufliegt. Wenn eine solche Kalanderwalze mit Silikongummi beschichtet ist, hat diese Beschichtung bei dem Kalander die Aufgabe, mit einer anderen Kalanderwalze unter Pressung zusammenzuwirken, wobei die äußere Schicht der Kalanderwalze eine bestimmte Härte aufweisen soll, die bei dem Kalander mit 55 Shore angegeben ist. Ein Kalander hat gegenüber einer Heißmangel- und Bügelwalze wesentlich andere Aufgaben zu erfüllen.AT-PS 229 259 is concerned with a heatable calender for consolidating nonwovens containing thermoplastic fibers. In the case of a calender, it is a matter of the outer layer resting very solidly on a cylindrical metal jacket or as an imperforate tube. If such a calender roll is coated with silicone rubber, this coating on the calender has the task of interacting with another calender roll under pressure, the outer layer of the calender roll should have a certain hardness, which is indicated for the calender as 55 Shore. A calender has significantly different tasks to perform than a hot ironing and ironing roll.

Aufgabe der Erfindung ist es, eine Bügel- bzw. Mangelwalze zu schaffen, deren Polsterlage bei gleichmäßiger Elastizität eine hohe Wärmebeständigkeit und dauerhafte Haltbarkeit sowie ein zuverlässiges und einwandfreies Abführen von Feuchtigkeit und des Kondensats gewährleistet. Die Erfindung zeichnet sich dadurch aus, daß die durch die Dicke der Polsterlage durchgehenden Lochungen in dem Bereich von 4 bis 10 mm Durchmesser gehalten und durch auf der Unterseite der Polsterlage angeordnete Nuten verbunden sind, daß die Polsterlage mit einer Netz- oder Geflecht-Einlage aus Glasfasern oder Metall versehen ist, die in dem Silikonmaterial einvulkanisiert ist, und daß der Silikongummi eine Shore- Härte in dem Bereich von 50 bis 75, vorzugsweise 55 bis 65, aufweist.The object of the invention is to provide an ironing or ironing roller, the cushioning layer of which, with uniform elasticity, ensures high heat resistance and long-term durability as well as reliable and flawless removal of moisture and the condensate. The invention is characterized in that the holes through the thickness of the cushion layer are held in the range of 4 to 10 mm in diameter and are connected by grooves arranged on the underside of the cushion layer, that the cushion layer is made of a mesh or braid insert Glass fibers or metal is provided, which is vulcanized into the silicone material, and that the silicone rubber has a Shore hardness in the range of 50 to 75, preferably 55 to 65.

Durch eine solche Vereinigung der Merkmale ergibt sich eine Polsterlage, die allen Ansprüchen der zum Teil widersprüchlichen Forderungen gerecht wird. Die Polsterlage der Erfindung verbürgt eine verhältnismäßig große Elastizität bei ausreichender Widerstandsfähigkeit. Dabei ist gewährleistet, daß eine große Absaugefähigkeit der Feuchtigkeit bzw. des Dampfkondensates, und zwar auch bei großer Pressung, gegeben ist. Die Lochungen bleiben auch unter hohen Drücken offen, was für die Funktionstüchtigkeit der Polsterlage unerläßlich ist. Die Polsterlage bzw. die Polsterstreifen der Erfindung besitzen eine hohe Verschleißfestigkeit und sind dauerhaft in der Haltbarkeit. Die Vorzüge bleiben trotz ihrer Widersprüchlichkeit beim Betrieb der Bügelwalze voll erhalten. Die genannten Eigenschaften ergeben sich durch das Zusammenwirken der vorstehend genannten Merkmale, die die Erfindung ausmachen, wobei eine Wechselwirkung zwischen den Merkmalen zu verzeichnen ist. Die erzielte Wirkung ist zuverlässig.Such a combination of features results in a cushioning layer that meets all requirements of the sometimes contradicting demands. The cushion layer of the invention guarantees a relatively high elasticity with sufficient resistance. This ensures that the moisture or steam condensate is highly absorbent, even with high pressure. The perforations remain open even under high pressures, which is essential for the functionality of the upholstery layer. The cushion layer or the cushion strips of the invention have a high wear resistance and are durable in durability. In spite of their contradicting nature, the advantages are fully retained when operating the ironing roller. The above-mentioned properties result from the interaction of the above-mentioned features that make up the invention, an interaction between the features being noted. The effect achieved is reliable.

Die kanalartigen Nuten auf der Unterseite des Silikongummis haben vorteilhaft eine Breite von 1 bis 2 mm. Vorteilhaft besitzt der Polsterstreifen eine dem Textilüberzug zugekehrte gerauhte Oberfläche.The channel-like grooves on the underside of the silicone rubber advantageously have a width of 1 to 2 mm. The cushioning strip advantageously has a roughened surface facing the textile covering.

Zweckmäßig sind die Enden des Polsterstreifens auf eine vorbestimmte Länge in der Höhe abgesetzt ausgebildet, so daß die Endteile sich in geeigneter Weise überlappen können. Die Befestigung der sich überlappenden Endteile an dem Stahlmantel der Trommel kann mittels Schrauben, Nieten od.dgl. erfolgen. Um hierbei ein Einreißen zu verhindern, ist vorteilhaft ein Blech aus nichtrostendem Material in dem Endteil einvulkanisiert, wobei das Blech mit Widerhaken versehen sein kann. Dadurch ergibt sich eine sichere und zuverlässige Verbindung von aneinandergesetzten Silikongummistreifen zur Bildung einer durchgehenden Polsterlage.The ends of the cushion strip are expediently offset in height to a predetermined length, so that the end parts can overlap in a suitable manner. The overlapping end parts can be attached to the steel jacket of the drum by means of screws, Rivets or the like respectively. In order to prevent tearing, a sheet of rust-proof material is advantageously vulcanized into the end part, whereby the sheet can be provided with barbs. This results in a secure and reliable connection of silicone rubber strips placed together to form a continuous cushion layer.

Die Bügel- oder Mangelwalze weist eine Stahltrommel 1 auf, die einen Trommelmantel 2 besitzt, der mit siebartig verteilten Lochungen 3 versehen ist. Zur Bildung einer Polsterlage federnder Art auf dem Umfang der Stahltrommel 2 dient ein Streifen 4, der auf dem gelochten Umfang der Stahltrommel 2 schraubenlinienförmig aufgewikkelt ist.The ironing or mangle roller has a steel drum 1 which has a drum jacket 2 which is provided with perforations 3 distributed in a sieve shape. To form a cushioning layer of resilient type on the circumference of the steel drum 2, a strip 4 is used, which is helically wound onto the perforated circumference of the steel drum 2.

Der Streifen 4 besteht aus temperaturbeständigem, insbesondere hitzebeständigem, zumindest bis 240°C, Silikongummi, der hinsichtlich seiner Elastizität eine Shorehärte in dem Bereich von 30 bis 70 aufweist. Vorzugsweise liegt die Shorehärte bei 55 bis 65. Der Silikongummi-Streifen weist im Innern mindestens eine netz- oder geflechtartige Einlage 5 aus Glasfasern oder Draht aus nichtrostendem Stahl, Messing od.dgl. auf, die in dem Silikongummi-Material einvulkanisiert ist. Der Silikongummi-Streifen ist ebenfalls mit Lochungen 6 versehen, die über die Fläche des Streifens regelmäßig oder unregelmäßig siebartig verteilt sind. Die Lochungen 6 gehen vollständig durch die Dikke des Streifens hindurch. Auf der oberen Seite, d.h. der dem Textilüberzug zugekehrten Seite, ist die Oberfläche des Silikongummi-Streifens mit einer Aufrauhung 7 versehen. Die Aufrauhung kann durch ein Anrauhen der Fläche auf mechanische oder chemische Weise erzeugt sein. Man kann die nach außen gekehrte Oberfläche des Streifens auch mit einer regelrechten Riffelung, vorzugsweise leichterer Art, ausstatten, z. B. mittels parallel verlaufender oder sich kreuzender Nuten geringer Tiefe. Auf diese Weise läßt sich ein Verrutschen des Textilüberzuges bei der Mangelarbeit mit Sicherheit vermeiden.The strip 4 consists of temperature-resistant, in particular heat-resistant, at least up to 240 ° C., silicone rubber which has a Shore hardness in the range from 30 to 70 in terms of its elasticity. The Shore hardness is preferably 55 to 65. The silicone rubber strip has at least one mesh-like or braid-like insert 5 made of glass fibers or wire made of stainless steel, brass or the like on the inside. which is vulcanized into the silicone rubber material. The silicone rubber strip is also provided with perforations 6, which are regularly or irregularly distributed in a sieve-like manner over the surface of the strip. The perforations 6 go completely through the thickness of the strip. On the top side, i.e. the side facing the textile cover, the surface of the silicone rubber strip is provided with a roughening 7. The roughening can be produced by roughening the surface in a mechanical or chemical manner. You can also equip the outwardly facing surface of the strip with a regular corrugation, preferably of a lighter type, e.g. B. by means of parallel or crossing grooves of shallow depth. In this way, slippage of the textile cover can be avoided with certainty when working with shortages.

Um eine Abführung von Luft und Dampf der dicht auf der Oberfläche der Trommel der Walze liegenden Polsterlage zu unterstützen, sind die Lochungen auf der der Trommel zugekehrten Seite des Streifens untereinander durch Kanäle, Nuten od.dgl. miteinander verbunden, wie dies aus der Fig. 4 zu ersehen ist. Diese Verbindungsnuten zwischen den Lochungen 6 gewährleisten ein vollständiges Abziehen der sich beim Mangeln bildenden Dämpfe od. dgl. in das Innere der Trommel und von dort mittels eines Ventilators nach außen. Kondenswasser u.dgl. kann in der Polsterlage nicht zurückbleiben. Die Nuten 8 verbinden zweckmäßig jede Lochung mindestens einmal mit der benachbarten Lochung. Die Nuten oder Kanäle 8 können in geeigneten Fällen auch nur waagerecht und/oder senkrecht zur Längsachse des Streifens verlaufen.In order to support the removal of air and steam from the cushion layer lying tightly on the surface of the drum of the roller, the perforations on the side of the strip facing the drum are interconnected by channels, grooves or the like. connected to one another, as can be seen from FIG. 4. These connecting grooves between the perforations 6 ensure that the vapors or the like formed during ironing are completely drawn off into the interior of the drum and from there to the outside by means of a fan. Condensed water and the like cannot remain in the upholstery position. The grooves 8 expediently connect each perforation to the adjacent perforation at least once. In suitable cases, the grooves or channels 8 can also only run horizontally and / or perpendicular to the longitudinal axis of the strip.

Die Polsterstreifen aus elastischem Silikongummi können so lang sein, daß sie zum Umwickeln der Trommel vom Anfang bis zum Ende ausreichen und ein Aneinandersetzen nicht erforderlich ist. Bei Trommeln größeren Durchmessers kann sich ein Aneinandersetzen der Streifen ergeben. Hierzu sind die Endteile der Streifen in der Höhe abgesetzt ausgebildet. Es ergeben sich Zungen 10 und 11 von etwa der halben Höhe des Streifens. Diese Zungen 10 und 11 werden zur gegenseitigen Überdeckung gebracht, wobei die Befestigung auf dem Stahlmantel der Trommel durch Schrauben, Nieten od.dgl. erfolgen kann, die durch vorbereitete Löcher 12 bzw. 13 hindurchgreifen. Zur Verbesserung der sich überlappenden Verbindung kann in einem Endteil ein Blech 14 einvulkanisiert sein, das mit Lochungen 15 versehen ist, die den Löchern 12 und 13 in den Zungen 10 und 11 entsprechen. Auf diese Weise wird die in der Verbindung entstehende Zugkraft auf eine größere Fläche des Endteils der Streifen übertragen. Das Blech 14 ist zweckmäßig auf beiden Seiten aufgerauht oder mit durch Stanzen erzielten Widerhaken od.dgl. versehen.The padding strips made of elastic silicone rubber can be so long that they are sufficient to wrap the drum from start to finish and do not need to be put together. In the case of drums of larger diameter, the strips may come together. For this purpose, the end parts of the strips are formed at different heights. There are tongues 10 and 11 of about half the height of the strip. These tongues 10 and 11 are brought to mutual overlap, the attachment to the steel jacket of the drum by screws, rivets or the like. can take place which reach through prepared holes 12 and 13 respectively. To improve the overlapping connection, a sheet 14 can be vulcanized into an end part, which is provided with perforations 15 which correspond to the holes 12 and 13 in the tongues 10 and 11. In this way, the tensile force arising in the connection is transmitted to a larger area of the end part of the strips. The sheet 14 is appropriately roughened on both sides or with barbs or the like obtained by punching. Mistake.

Je nach der Größe der Trommel, die in dem Bereich von 180 mm bis etwa 1.600 mm liegen kann, können die Streifen in der Dicke unterschiedlich sein. Für den mittleren Bereich der Trommelgrößen werden die Silikongummi-Streifen in einer Dicke von etwa 8 bis 12 mm gehalten. Die Lochungen 6 können hierbei 4-10 mm betragen. Die Lochungen auf der hohlen Stahltrommel sind im allgemeinen wesentlich größer, z. B. 12 bis 15 mm im Durchmesser. Durch die Vielzahl der Lochungen in dem Mantel der Stahltrommel und in den aufgewickelten Streifen aus Silikongummi ist die Gewähr gegeben, daß eine genügende Anzahl von Lochungen des Streifens und der Trommel sich überdecken, so daß einem Abziehen des Dampfes u.dgl. kein Hindernis entgegensteht. Die Breite des Streifens für den mittleren Größenbereich der Trommel kann zwischen 40 bis 60 mm schwanken. Vorteilhaft ist eine Standardbreite von 50 mm. Bei kleineren Trommelgrößen kann zum Aufwickeln der Streifen mit glatter Unterlage die Breite derselben geringer gehalten werden, z. B. bis etwa 25 bis 30 mm heruntergehen. Die kanalartigen Nuten 8 können eine Breite von 1 bis 2 mm haben.Depending on the size of the drum, which can be in the range from 180 mm to about 1,600 mm, the thickness of the strips can vary. For the middle range of drum sizes, the silicone rubber strips are held in a thickness of approximately 8 to 12 mm. The perforations 6 can be 4-10 mm. The holes on the hollow steel drum are generally much larger, e.g. B. 12 to 15 mm in diameter. Due to the large number of perforations in the jacket of the steel drum and in the wound strips of silicone rubber, there is a guarantee that a sufficient number of perforations of the strip and the drum will overlap, so that the steam can be drawn off and the like. there is no obstacle. The width of the strip for the medium size range of the drum can vary between 40 and 60 mm. A standard width of 50 mm is advantageous. In the case of smaller drum sizes, the width of the same can be kept smaller, e.g. B. go down to about 25 to 30 mm. The channel-like grooves 8 can have a width of 1 to 2 mm.
