Description

Walze für Maschinen der Papierfabrikation und ähnliche Zwecke Die Erfindung betrifft die Herstellung von Walzen mit Überzug aus elastischem Stoff, wie sie in der Papierfabrikation und verwandten Gebieten als Gautsch-, Preß-, Glatt-, lialander-, Feucht-, Auftrag-, Andruck- u. dgl. Walzen vielfach verwendet werden. Diese Walzen sind meist in der Weise hergestellt, daß um den Walzenkörper ein Wickelband aus Filz oder anderem elastischen Stoff schraubengangförmig gewickelt ist. Der feste Sitz des Wickelbandes soll dabei durch einen in das Wickelband eingelegten und beün Wickeln gespannten Faden, Draht oder Seil gewährleistet sein. Es hat sich indessen gezeigt, daß hei dieser mechanischen Adhäsionsbefestigung trotz sorgfältigster Ausführung die Bewickelung infolge der hohen Beanspruchungen im Betriebszustand auf dem Walzenkörper verrutscht und vorzeitig unbrauchbar wird.Rollers for paper-making machines and similar purposes Die The invention relates to the production of rollers with a cover made of elastic material, as they are used in paper manufacture and related areas as yarn, press, smooth, Lialander, dampening, application, pressure and the like rollers are widely used. These rollers are usually made in such a way that a winding tape is provided around the roller body made of felt or other elastic material is wound in a helical manner. The firm one The seat of the wrapping tape should be inserted into the wrapping tape and beün Winding of tensioned thread, wire or rope can be guaranteed. It has meanwhile been shown that this mechanical adhesive fastening despite the most careful execution the wrapping as a result of the high stresses in the operating state on the roller body slips and becomes unusable prematurely.

Die Erfindung bezweckt die Herstellung eines unverrutschbaren Wickelbezuges mittels wirklichen Eingriffes zwischen Walzenkörper und Wickelband.The invention aims to produce a non-slip wrap cover by means of real engagement between the roller body and the winding belt.

Die Herstellung des Wickelbezuges gemäß der Erfindung ist beispielsweise veranschaulicht, und zwar in Abb. r, z und 3 in Schnitten senkrecht zur Walzenachse. Die Umfläche des Walzenkörpers d ist mit Vor- und Rücksprüngene, wie z. B. Rippen, Rillen, Nuten, Zähne o. dgl., versehen. Das Wickelband a erhält in seiner Sitzfläche auf dem Walzenkörper gleichfalls Vor- und Rücksprünge (Auskerbungen, Zähne u. dgl.), derart, daß, die Vorsprünge des Wickelbandes beim Bewickeln in die Rücksprünge des Walzenkörpers treten. Dabei ist es vorteilhaft, die Teilung der Vor-und Rücksprünge des Wickelbandes kleiner zu wählen als die der Vor- und Rücksprünge des Walzenkörpers, in die der Eingriff .erfolgt, um durch Dehnung des Wickelbandes eine Spannung in dem Wickelbezug zu erzeugen. Das Wickelband wird durch :eigene Spannung oder durch den Wickelfaden b im Eingriff festgehalten, so daß sein unverrutschbarer Sitz gewährleistet ist.The manufacture of the wrap cover according to the invention is for example illustrated, namely in Fig. r, z and 3 in sections perpendicular to the roll axis. The outer surface of the roller body d is provided with projections and recesses, such as. B. ribs, Grooves, grooves, teeth or the like., Provided. The wrapping tape a receives in its seat on the roller body also protrusions and recesses (notches, teeth, etc.), such that the projections of the winding tape when winding in the recesses of the Roller body kick. It is advantageous to divide the projections and recesses of the winding belt to be smaller than that of the projections and recesses of the roller body, in which the engagement. takes place in order to create a tension in to produce the wrap cover. The wrapping tape is made by: own tension or by the winding thread b held in engagement so that its non-slip seat is guaranteed is.

Das Bewickelungsverfahren ist z. B. auch bei den Walzen der Tapetenfabrikation anwendbar.The winding process is z. B. also with the rollers of the wallpaper production applicable.
