<p>A polyhedral member (1) having an axis of rotation (B), for use in apparatus which comprises at least three such polyhedral members rotatably mounted with their said axes of rotation equidistantly disposed on an imaginary circle (a), for cutting and shaping a bar-shaped dough body (10), such polyhedral member comprising upper and lower parallel planar surfaces (17) between which the member has a predetermined thickness (T), two opposite side surfaces (11,12), each of which is formed along an arc (y1,y2) whose radius is equal to the rectilinear distance (a') between two adjacent ones of said axes in said apparatus, and two tips (2) at which the two side surfaces abut each other and which form cutting edges, the arrangement being such that when the tips of the polyhedral members in said apparatus are positioned at the centre of the said circle, each of the centres (x1,x2) of the arcs that correspond to the two said side surfaces of the polyhedral member is located at a distance from the axis of the member that is equal to the radius (R) of the said circle and at a distance from the centre of the circle that is equal to the said distance (a') between two adjacent axes, and wherein the members form between themselves an opening (3) that is closed and opened by the rotational movement of the members. <IMAGE></p> |
