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.
