  • Patent number: 5786016
    Abstract: Dough shaping devices for shaping baker's dough pieces include a pair of cooperating shaping members, such as concave rounder bars (27) placed over a surface conveyor (16). The concave surface of the rounder bars is formed with a metal base plate (45) that includes a concave dough shaping surface (46) formed of stainless steel. Metal particles are formed on the dough shaping surface by the sputtering of metal plasma, to form a roughened texture, and a slick material, such as a fluropolymer, is applied thereover, to form a grainy but slick surface against which the dough pieces move. The grainy surface retards sliding friction of the dough pieces, while the slick surface permits immediate release of the dough from the dough shaping surface.
