Abstract
An assembly for cutting and shaping a bar-shaped dough body including a plurality of polyhedral cutting members disposed around an opening through which the bar-shaped dough body is extruded. The polyhedral members are rotatably mounted around the opening and are formed to cooperatively close the opening, thereby cutting the bar-shaped dough body, multiple times during each revolution of the polyhedral members. Each polyhedral member includes curved sides meeting at one or more tip edges, the tip edges of each of the polyhedral members meeting at a center of the opening when the bar-shaped dough body is cut.

A polyhedral member used in an assembly for cutting and shaping a bar-shaped dough body, wherein the assembly comprises at least three of the polyhedral members pivotally supported through shafts that are equidistantly disposed on an imaginary circle, each polyhedral member comprising:
- upper and lower parallel plane surfaces, the upper and lower planes being separated by a predetermined thickness,
- two longitudinal side surfaces, each of which being formed along an arc having a radius which is equal to a distance between two adjacent shafts, and
- two tips at which the two longitudinal side surfaces abut each other, the tips forming cutting edges,
- wherein when the tips of the polyhedral members are positioned at a center of the circle, each of the centers of the arcs corresponding to the two side surfaces of the polyhedral members is located at a distance from the shaft of a member that is equal to the radius of the circle, and at a distance from the center of the circle that is equal to the distance between two adjacent shafts, and
- wherein the members form between themselves an opening that can be closed by the rotational movement of the members.
An apparatus for cutting and shaping a bar-shaped dough body comprising at least three polyhedral members, each polyhedral member comprising:
- upper and lower parallel plane surfaces, the upper and lower planes being separated by a predetermined thickness,
- two longitudinal side surfaces, each of which being formed along an arc having a radius which is equal to a distance between two adjacent shafts, and
- two tips at which the two longitudinal side surfaces abut each other, the tips forming cutting edges,
- wherein when the tips of the polyhedral members are positioned at a center of the circle, each of the centers of the arcs corresponding to the two side surfaces of the polyhedral members is located at a distance from the shaft of a member that is equal to the radius of the circle, and at a distance from the center of the circle that is equal to the distance between two adjacent shafts, and
- wherein the polyhedral members are associated such that the members radially and collectively close an opening concentric to the circle, a tip portion of one polyhedral member tracks the side surface of an adjacent polyhedral member, and wherein the opening is confined through the side surfaces of the polyhedral members by the rotary movement thereof so that the bar-shaped dough body passing through the opening is cut and shaped.
An apparatus for cutting a bar-shaped dough comprising three identically-shaped polyhedral members, each member being rotatably fitted to one of three shafts that are equidistantly disposed on an imaginary circle such that the members radially and collectively close an opening concentric to the circle, wherein each of the members has three sides forming a tip between every two adjacent sides, each side being formed along an arc having a radius equal to a distance between two adjacent shafts,
- wherein when one of the tips is positioned at the center of the circle each center of the arcs that correspond to the two sides that abut each other at the circle's center is at the same time located at a distance from the shaft of a member that is equal to the radius of the circle and at a distance from the center of the circle that is equal to the distance between two adjacent shafts, the center of the arc corresponding to the remaining side is located at the center of the circle, and
- wherein the members are associated such that the opening is closed by the rotation of the members so that the bar-shaped dough body passing through the opening is cut and shaped.
A polyhedral member used in an assembly for cutting and shaping a bar-shaped dough body, the polyhedral member comprising:
- a central axis;
- a first surface disposed perpendicular to the central axis, the first surface having first and second curved sides meeting at first and second tips, each of the first and second tips being formed at a common distance from the central axis and being positioned such that the central axis, the first tip and the second tip are aligned along a first line;
- wherein a shape of the first curved side is defined by a first arc having a first central point located at the common distance from the central axis, and a shape of the second curved side is defined by a second arc having a second central point located at the common distance from the central axis;
- and
- wherein the central axis, the first central point and the second central point are aligned along a second line, the second line being perpendicular to the first line.
