Abstract

To apply and remove an elastic cladding from rollers, such as for the papermaking industry, the cladding (3) to be applied is carried by a thin-walled tube (2), passed over the roller (1) in an axial sliding motion, and secured in place by local welding spots (4). For removal, the welding spots (4) are cleared and the tube (2) together with the cladding (3) is removed from the roller (1). ADVANTAGE - The roller surface is not affected by the cladding, and requires no cleaning when the cladding is removed for exchange.

Description

Die Erfindung betrifft Verfahren zum Aufbringen oder Entfernen elas­ tischer Beschichtungen auf Walzen, wie sie besonders in der Papier- und Textilindustrie zum Einsatz des Bedruckens, Transportierens, Be­ feuchtens u.s.w. gelangen.The invention relates to methods for applying or removing elas coatings on rollers, such as those found in paper and textile industry for the use of printing, transport, loading damp etc. reach.

Bei der Wiederaufarbeitung solcher Walzen besteht das Problem des Ent­ fernens des auf den Walzenkörper vulkanisierten Überzuges. Dieser wird beispielsweise durch induktives Erwärmen des Eisenkernes der Walze von dieser gelöst, wobei nicht unbedenkliche Gase entstehen. Danach muß zur Reinigung und Entfettung des Walzengrundkörpers eine Behandlung mit fettlösenden Chemikalien, beispielsweise Per, vorge­ nommen werden, um eine neue elastische Beschicntung aufbringen zu können.When reprocessing such rolls, there is the problem of Ent far from the coating vulcanized on the roller body. This is achieved, for example, by induction heating of the iron core the roller detached from it, producing harmless gases. Then a must for cleaning and degreasing the roller body Treatment with fat-dissolving chemicals, for example Per, pre be taken to apply a new elastic coating can.

Gegen die Verwendung von Per wird seitens des Umweltschutzes massiv vorgegangen.Environmental protection is massive against the use of Per proceeded.

Der Erfindung liegt die Aufgabe zugrunde, das im Oberbegriff des An­ spruchs 1 beschriebene Verfahren so zu gestalten, daß die beschriebe­ nen, umweltbelastenden Nachteile vermieden werden.The invention is based, which in the preamble of the task Proverb 1 described to design so that the described environmental disadvantages can be avoided.

Die Lösung der Aufgabe besteht nach der Erfindung in den im kenn­ zeichnenden Teil des Anspruchs 1 aufgeführten Merkmalen.The object is achieved according to the invention in the drawing part of claim 1 listed features.

Im folgenden wird das erfindungsgemäße Verfahren anhand einer Zeichnung gezeigt:In the following, the method according to the invention is based on a drawing shown:
