Abstract: A die assembly for holding a bas-relief military decoration to a ribbon while gluing the two together. The die assembly has mating top and bottom halves, and sandwiches both the ribbon and the decoration therewithin. The decoration is placed in a die which conforms to the front, or visible side, so as to hold the same immovably. The die is held in a recess formed in the bottom half. The ribbon is placed in a slide groove located in the top half. Glue is applied to the exposed rear surface of the decoration. The two halves are then pressed together, and the ribbon and decoration are also pressed together, and united. Precise alignment of the decoration and ribbon, and between die assembly upper and lower halves, is provided by cooperating guides formed in the die assembly. A hole is formed in the top half, to accommodate prongs formed in the decoration. This enables retention of these prongs, rather than requiring bending them back or removing them prior to mounting the decoration.
