Description

Die bisher bekannten elektrischen Heizeinrichtungen für Walzen müssen infolge unmittelbarer Berührung von Heizelement und Walze mit Sorgfalt und großem. Zeitaufwand angelegt werden, damit nicht durch ungenügende Berührung eine Überhitzung der Heizelemente eintritt. Begünstigt wird das hierdurch erfolgende Durchbrennen der Heizdrähte durch die meistens glatt geschliffenen und stark reflektierenden Walzen. "Außerdem ist bei den bekannten Einrichtungen durch ihre halbstarre Ausführung der Anwendungsbereich sehr klein, was bei der öfters großen Verschiedenheit der Walzendurchmesser nachteilig ist.The previously known electrical heating devices for rollers have to be immediate as a result Touching the heating element and roller with care and great care. Expenditure of time to prevent overheating of the Heating element enters. The resultant burn-through of the heating wires is favored due to the mostly smooth and highly reflective rollers. "Aside from that is the area of application of the known devices due to their semi-rigid design very small, which is a disadvantage given the often large differences in the roller diameters is.

Durch Trennung von Heizdraht und Walze gemäß der Erfindung werden die obigen Nachteile vermieden und außerdem eine richtige Verteilung der Heizleistung erzielt. By separating the heating wire and roller according to the invention, the above Avoided disadvantages and also achieved a correct distribution of the heating power.

Die Zeichnung stellt die Einrichtung in einer Ausführungsart dar. Die elektrischen Heizelemente (Spiralen) α sind von einem gegen Wärmeverluste isolierten Gehäuse b umgeben. An der an den Walzen aufliegenden Seite befinden sich Bänder C1 bestehend aus kettenartig zusammengesetzten Gliedern. Die Bänder sind oben und unten mit dem Gehäuse fest, in der 'Mitte jedoch durch Scharniere u? beweglich verbunden, so 'daß sich die Bänder beim Anlegen der Heizeinrichtung an 3» die Walzen von selbst spannen und den jeweiligen Walzengrößen anpassen. Die Stirnwände des Gehäuses sind verschiebbar, so daß sie ebenfalls dem Walzendurchmesser weitgehend angepaßt werden können.The drawing shows the device in one embodiment. The electrical heating elements (spirals) α are surrounded by a housing b which is insulated against heat losses. On the side resting on the rollers there are belts C 1 consisting of links assembled like a chain. The straps are fixed to the housing at the top and bottom, but in the middle by hinges u? movably connected, so that when the heating device is applied to the rollers, the belts tension themselves and adapt to the respective roller sizes. The end walls of the housing are displaceable so that they can also be largely adapted to the roller diameter.

Damit eine gleichmäßige Beheizung der Walzen stattfindet, wird eine genau gleich ausgebildete (Hälfte) Heizeinrichtung an der anderen Walzenseite angelegt, derfen Zeichnung und Beschreibung sich erübrigt.So that the rollers are heated evenly, one is exactly the same trained (half) heater applied to the other side of the roll, derfen drawing and description is unnecessary.
