Abstract

The invention relates to a forming device for forming and partitioning a pasty food strand as well as to a filling machine with a respective forming device and to a method. The forming device comprises more than two flat displacement elements superposed in the direction of transport of the food strand, each having at least one opening through which the food strand can be moved in the direction of transport. The forming device further comprises a movement mechanism for moving the flat displacement elements on respective curved paths, such that the respective openings can move relative to each other, so that the cross-sectional area of the resulting overall opening of the superposed openings changes.

First claim

The invention claimed is:

1. A forming device for forming and partitioning a pasty food strand, comprising:
more than two flat displacement elements superposed in a direction of transport of said food strand, each having at least one opening through which said food strand is movable in said direction of transport, and
a movement mechanism for moving said flat displacement elements on respective curved paths, such that said respective openings of said flat displacement elements are superposed and movable relative to each other so that a cross-sectional area of a resulting overall opening of said superposed openings changes,
wherein said movement mechanism comprises at least one rotary member, and wherein said flat displacement elements are coupled and distributed about a circumference of said rotary member.

2. The forming device according to claim 1 , wherein said movement mechanism is configured such that said flat displacement elements are movable to a severing position in which said openings are aligned to each other such that no overall opening exists and are movable to an open position in which the cross-sectional area of said overall opening has a predetermined maximum cross-section.

3. The forming device according to claim 2 , wherein during a motion of a total number, n, of the flat displacement elements from said open position to said severing position, edges of said openings defining said overall opening move from n sides in a direction toward a center M of said overall opening and during the motion of the n flat displacement elements from said severing position to said open position, said edges of said openings can move toward the n sides away from said center M.

4. The forming device according to claim 1 , wherein said openings have an enclosed circumference and/or are formed round or oval or at least have curved sections.

5. The forming device according to claim 1 , wherein said respective flat displacement elements each comprise multiple adjacently disposed openings for multiple food strands.

6. The forming device according to claim 1 , wherein said flat displacement elements are, at their two oppositely disposed end portions, rotatably mounted on a respective rotary member.

7. The forming device according to claim 1 , wherein said at least one rotary member is driven.

8. The forming device according to claim 7 , wherein said at least one rotary member is driven in two directions of rotation and/or multiple rotary members are driven.

9. The forming device according to claim 1 , wherein said movement mechanism comprises multiple rotary members on one side,
where at most one flat displacement element is respectively coupled on its end portion at a front or rear side of said rotary members and is at its other end portion guided on a respective path.

10. The forming device according to claim 1 , wherein coupling points of said flat displacement elements on said rotary member exhibit varying distances to a central axis of said rotary member.

11. The forming device according to claim 1 , wherein said forming device further comprises a controller which controls said movement mechanism, including a position of said flat displacement elements in dependence of time and an extrusion speed of said food strand.
