Abstract

"PRECIOUS METAL POSTAL SEAL MANUFACTURING PROCEDURE" characterized by the fact that the precious metal is laminated in different rolling mills and in parallel it is forged by hammer blows and by hand, making this special forging in the form of a swallowtail, in order to influence in the structure of the sheet and give it excessively great flexibility; the thickness of the sheets is varied from 0.05 mm to 0.20 mm and they are later coated with an adhesive, stamping and cutting them in stamps of the previously determined size.
