Definitions

• the invention relates to a method for structuring the surface of a bare metal sheet
• 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.
• an adhesive film is placed on at least one surface of the sheet and pressed against the surface of the sheet with a roller, thereby deformed with the sheet and the impression of the deformed sheet is pressed into the sheet surface, the desired surface structure of the sheet being achieved in that the ratio of the peripheral speed of the roller to the feed speed of the sheet and the roller pressure can be selected accordingly.
• the deformation of the film when rolled on can be changed and the quality of the surface can be controlled.
• 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 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 adhesive film has a surface structure on the side facing the sheet metal. In this way, additional surface structuring can take place.
• This method can also be used to achieve a considerable reduction in sheet thickness and to save a roll pass that is otherwise necessary.
• the sheet consists of 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.
