An apparatus for preparing rolled pieces of pastry includes at least four adjacent rollers having parallel axes, being capable of defining a substantially cylindrical cavity, being adapted to rotate in the same direction and being adapted to rotate at a same peripheral speed. Means are provided for forming and then closing an admitting gap between two of the rollers for admitting pieces to be rolled into the cavity for rolling. Means are provided also for forming a releasing gap between two of the rollers for releasing rolled pieces from the cavity.
