Definitions
- the sheet is formed either by grinding, polishing or by embossing a structured surface.
- the negative structure is on an embossing body, which can be a plate or a roller or a belt.
- embossed bodies are made specifically for each structure. They are expensive and wear out. If large quantities of sheet metal are to be processed, the outlay on equipment to enable the stamping body to be positioned exactly is high. Furthermore, it must be ensured that no dirt or chips come between the embossing body and the sheet. It is therefore necessary to clean the embossing body at certain intervals. In order to protect the treated surface from dust and damage, the sheet must be packed after the process or the treated surface must be covered with a film.
- this is remedied by placing an adhesive film on at least one surface of the sheet, pressing it against the surface of the sheet by a roller, thereby deforming it with the sheet and pressing the impression of the deformed sheet into the sheet surface.
- the film used can also be completely smooth. This creates a characteristic surface structure on the sheet. The profiling is done only by deforming the film during rolling.
- the film used is only used once. It is therefore any wear on the film is insignificant.
- the film and the construction of the system are comparatively low.
- the film it is conceivable to first place the film on the sheet and then roll it on, or to apply the film between the sheet and the roller to the sheet and roll it on at the same time. If the film is to remain on the treated surface as transport protection, the film is coated with adhesive on the side facing the sheet. If the film should only provide protection for storage purposes, it is not necessary to use a film with an adhesive layer, since the surfaces of the sheet and the film are pressed together during the rolling process in such a way that they interlock as it were and thus adhere well to one another. This ensures good surface protection even in this application.
- the method can also be carried out in such a way that the film used has a surface structure on the side facing the sheet metal. In this way, additional surface structuring can take place.
- a further possibility of carrying out the process according to the invention can be such that the deformation of the film and the sheet is controlled by changing the ratio of the peripheral speed of the roll to the feed speed of the sheet and the roll pressure of the rolls. In this way, the deformation of the film during rolling can also be changed and the quality of the surface controlled.
- This method can also be used to achieve a considerable reduction in sheet thickness and to save the otherwise necessary rolling pass.
- the sheet used consists of soft pure aluminum or a soft aluminum alloy.
- the surface can be shaped well and low forces are required for structuring.
- Our process can produce sheets with very diffuse light scattering, which are particularly suitable as optical reflectors.
- Sheets can also be produced for forming purposes, which have a particularly good lubricant entrainment effect and are particularly easy to deep-draw due to the addition of lubricating pads.

Abstract
Description
- Bei üblichen mechanischen Oberflächenbehandlungen wird das Blech entweder durch Schleifen, Polieren oder durch Einprägen einer strukturierten Fläche ausgebildet. Bei allen Prägeverfahren liegt die negative Struktur auf einem Prägekörper vor, der eine Platte oder eine Walze oder ein Band sein kann.
- Diese Prägekörper werden eigens für jede Struktur hergestellt. Sie sind teuer und verschleißen. Falls große Mengen von Blech verarbeitet werden sollen, ist der apparative Aufwand, um ein exaktes Positionieren des Prägekörpers zu ermöglichen, hoch. Weiters muß sichergestellt werden, daß kein Schmutz oder keine Späne zwischen den Prägekörper und das Blech gelangen. Daher ist es nötig, in gewissen Intervallen den Prägekörper zu reinigen. Um die behandelte Oberfläche von Staub und Beschädigungen zu schützen, muß das Blech nach dem Vorgang verpackt oder die behandelte Oberfläche mit einer Folie überzogen werden.
- Erfindungsgemäß wird dadurch Abhilfe geschaffen, daß wenigstens auf einer Oberfläche des Bleches eine Haftfolie aufgelegt, diese durch eine Walze gegen die Oberfläche des Bleches gedrückt, dadurch mit dem Blech verformt wird und der Abdruck der verformten Folie in die Blechoberfläche eingedrückt wird. Die verwendete Folie kann dabei auch vollkommen glatt sein. Es wird dadurch eine charakteristische Oberflächenstruktur auf dem Blech erzeugt. Die Profilierung erfolgt lediglich durch die Veformung der Folie während des Anwalzens.
- Die verwendete Folie wird nur einmal eingesetzt. Es ist daher jeder Verschleiß an der Folie unerheblich. Die Folie und der konstruktive Aufbau der Anlage ist vergleichsweise niedrig.
- Es ist dabei denkbar, die Folie zuerst auf das Blech aufzulegen und daraufhin anzuwalzen oder auch die Folie zwischen dem Blech und der Walze auf das Blech aufzubringen und gleichzeitig anzuwalzen. Soll die Folie als Transportschutz auf der behandelten Oberfläche bleiben, ist die Folie auf der dem Blech zugewandten Seite mit Klebemittel beschichtet. Falls die Folie lediglich zu Lagerzwecken einen Schutz ermöglichen soll, ist es nicht nötig, eine Folie mit Klebeschicht zu verwenden, da während des Walzvorganges die Oberflächen des Bleches und der Folie so aneinandergedrückt werden, daß sie gleichsam zueinander verzahnen und dadurch gut aneinander haften. Somit ist auch in diesem Anwendungsfall ein guter Schutz der Oberfläche gegeben. In weiterer Ausgestaltung kann das Verfahren auch so durchgeführt werden, daß die verwendete Folie auf der zum Blech weisenden Seite eine Oberflächenstruktur aufweist. Auf diese Weise kann eine zusätzliche Oberflächenstrukturierung erfolgen.
- Eine weitere Möglichkeit das erfindungsgemäße Verfahren durchzuführen, kann so erfolgen, daß durch Veränderung des Verhältnisses der Umfangsgeschwindigkeit der Walze zur Vorschubgeschwindigkeit des Bleches und des Walzenandruckes der Walzen die Verformung der Folie und des Bleches gesteuert wird. So kann die Verformung der Folie beim Anwalzen zusätzlich verändert und die Beschaffenheit der Oberfläche gesteuert werden.
- Es ist ein besonderer Vorzug unserer Verfahren, daß keine besonders polierte Strukturwalze eingesetzt werden muß, sondern mit normal glänzenden Walzen gearbeitet werden kann.
- Weiters kann mit dieser Methode auch eine beträchtliche Blechdickenreduktion erreicht und ein sonst notwendiger Walzstich eingespart werden.
- Es ist besonders vorteilhaft für dieses Verfahren, daß das verwendete Blech aus weichem Reinaluminium oder einer weichen Aluminiumlegierung besteht. Bei einem solchen Blech ist die Oberfläche gut formbar und werden für die Strukturierung geringe Kräfte benötigt.
- Durch unser Verfahren können Bleche mit sehr diffuser Lichtstreuung erzeugt werden, die sich besonders als optische Reflektoren eignen.
- Es können auch Bleche für Umformzwecke hergestellt werden, die einen besonders guten Schmiermittel-Mitnahme-Effekt aufweisen und durch den Anbau von Schmierpolstern besonders gut tiefziehbar sind.
