ABSTRACT:
Apparatus for molding clay into flat slabs for subsequent processing into pottery ware or sculpture employs a drive board for containing clay which is driven through a roller assembly. The clay is contained in a canvas to avoid adhesion of the clay to the roller, while the drive board includes a second canvas which assists driving the board through the roller assembly. An improved driving system utilizes an abrasive finish on the drive roller and a rubberized bottom on the drive board, while the upper roller functions as a guide roller for the slab. The thickness of the slab is adjustable by controlling the distance between the rollers.
