- the invention relates to a method for repair and / or repair of minor surface damage in a large format press plate or a Endless band made of sheet steel with a structured surface for surface embossing Holztechnikstoffen- or laminate panels, with the defective Surface is subjected to a microgalvanic treatment.
- the finished press plates are installed in a pressing device, with which the plastic-coated furniture boards or the like are made.
- a pressing device for example, circulating endless belts are used, which enable a continuous production, wherein pressed between the endless belts, the pressed material to plates and the surface is structured.
- the endless belts or press plates have the already mentioned surface structure which is impressed into the press laminate. Existing surface damage are so far impressed in the pressed material, if any, so that the manufactured possibly damaged plates can not be used to the full extent for further production. For this reason, it is particularly important that the press plates or endless belts used have absolutely flawless surfaces in order to keep the resulting blanks as small as possible.
- the process is used for large format press plates or endless belts applied to rework these surface defects or damaged areas, so that the relatively expensive press plates or endless belts continue can be used.
