Abstract: A method and a machine for the production from relatively thick flat pieces of frozen meat, for example roast beef, of thin slices suitable for roasting or grilling. The method is characterized by the fact that the flat meat pieces, before thawing above the freezing point taking place, are passed through a channel-shaped space of flat rectangular cross-section and of decreasing height in the direction of conveyance, which space is formed between two opposite endless conveying belts running in the same direction and in which the meat pieces are mangled and rolled to a desired final slice thickness substantially without loss of meat juice and blood.
