Two-stage embossing and punching out of thin materials for production of discs for bottle caps or covers for coins involves heat embossing followed immediately by relief embossing

摘要

Material(11) is heat embossed first followed by relief embossing and then the embossed area is punched out of the material. An Independent claim is included for the process equipment including separate heat embossing(17) and relief embossing(20) heads followed by a punching unit(22). The two embossing stages are carried out immediately after one another. Material may be either a coated or uncoated film of metal or plastic or a coated or uncoated paper and can be in strip or sheet form.
