The Digital Piano and the Patch Control Language System

Two defleshing machines of the type disclosed in U.S. Pat. No. 3,552,157 are modified so that they receive skins to be defleshed through respective feed openings directed in opposite horizontal directions, and discharge the defleshed or partly defleshed skins downwardly. A transfer conveyor receives the skins discharged from the first machine and raises them to the feed opening of the second machine. If the feed openings are directed toward each other, the skins are discharged from the second machine to an off-loading conveyor with their hair sides up. If the feed openings are directed horizontally away from each other, the fully defleshed skins are discharged to the off-loading conveyor with their flesh sides up.
