摘要： An apparatus and method for manufacturing leather coin pouches. The method provides for wetting a leather assembly comprising a substantially flat, flexible leather cover laminated to a substantially flat, more rigid centerpiece, to soften the leather which facilitates the eventual forming of the leather. The method further comprises creasing the leather in a creasing die. After a preforming step designed to foldedly bias the leather assembly toward forming as desired, the leather assembly is formed into a foldedly raised leather assembly with an overlapping flap spiral closure. Finally, while its formed shape is retained, the leather assembly is dried.The apparatus comprises a wetter for wetting the leather assembly, a creasing die for creasing the leather assembly into a creased leather assembly, a frusto-conical male/female preforming die for preforming the creased leather assembly, a forming die for forming the creased leather assembly into a foldedly raised formed leather assembly with a spiral closure, and an oven for drying the formed leather assembly.
