Abstract
Abstract Conveying apparatus for embossing machines for producing printing plates for address printing machines or for identification means made out of sheet metal or plastic material. The embossing machine conveying apparatus is capable of moving the printing plates in two directions which are perpendicular to each other. One of these directions is the direction required for character embossing within a print or read line and the second direction, which is perpendicular to the first, is in the direction of line spacing.
