The most common method and apparatus for embossing of sheet metal (whole cross and longitudinal) is using a roll mill and roll forming machine producing profile shape along the length of sheet. This proposed invention presents a new "UNIQUE" metal sheet made from two separate sheets that are pressed and punched (embossed and/ or coined) together (cold welding procedure) to make a single sheet .The embossing shape is not profile type and can be produced in longitude and cross pattern. Also these two sheets can be made of different materials to obtain the desired characteristics of each metal sheet . These sheets can be used in wall ,roof or deck panels and other areas that metal sheets metal are used. |
