  • Patent number: 4319523
    Abstract: Apparatus supports each of several dies for concurrent application of equal displacement of all such dies relative to the to-be-embossed leather strip surface. The apparatus applies sufficient force to all of several dies, each of which provide different resistances to leather penetration to develop equal displacement of each of such dies into the leather and thereby provide embossed structure of uniform characteristic by all of said dies to produce a particular ornamental and decorative effect. The dies may be readily and rapidly replaced for a variety of names to different leather strips.
