Abstract

A bread cutting machine has a circular blade that is moveable in a guide gap through an extension gap of a machine housing from a waiting position into a cutting space. When the blade is in the waiting position, the guide gap is coverable by a rocker displaceable away from the guide gap simultaneously with the extension of the blade from the waiting position, whereby the guide gap is opened. A cover plate is rigidly fastened to a side surface of the rocker, projects vertically away from the rocker, and covers the extension gap whenever the blade is in the waiting position. By a positive guide, the cover plate is moveable away from the extension gap simultaneously with the movement of the rocker, whereby the extension gap is opened.

First claim

What is claimed is:

1. A bread cutting machine for cutting off slices of cuttable material the bread cutting machine comprising:
a cutting device comprising a circular blade, which is mounted in a waiting position in a machine housing and configured to be driven by a motor enclosed by the machine housing,
wherein the circular blade is rotatably fastened to a blade arm,
wherein a cutting space for the cuttable material is formed on or in the machine housing,
wherein the cutting space has a guide gap,
wherein the circular blade is moveable in the guide gap through an extension gap of the machine housing from the waiting position into the cutting space by moving the guide arm,
wherein a hood for covering the circular blade in operation is arranged on the machine housing,
wherein the bread cutting machine has a protrusion that engages with the hood,
wherein when the circular blade is in the waiting position, the guide gap is coverable by a rocker displaceable orthogonally to a movement direction of the circular blade,
wherein the rocker is displaceable away from the guide gap simultaneously with the extension of the circular blade from the waiting position, whereby the guide gap is opened,
wherein, a cover plate is rigidly fastened to a cuttable-material-side surface of the rocker, projects vertically away from the rocker, and covers the extension gap whenever the circular blade is in the waiting position, and
wherein, by a positive guide, the cover plate is moveable away from the extension gap simultaneously with the movement of the rocker, whereby the extension gap is opened.

2. The bread cutting machine according to claim 1 , wherein the cover plate is configured to be displaced together with the rocker.

3. The bread cutting machine according to claim 2 , wherein the cover plate is configured to be linearly displaced together with the rocker.

4. The bread cutting machine according to claim 1 , wherein the cover plate and the rocker have an adhesive connection or a welded connection.

5. The bread cutting machine according to claim 1 , wherein the cover plate has a lateral recess which is dimensioned such that the circular blade in the waiting position is projectable into the recess at most so far that it does not reach the side of the cover plate facing away from the blade.

6. The bread cutting machine according to claim 1 , wherein the cover plate has a recess.

7. The bread cutting machine according to claim 1 , wherein the cover plate has a thickness between 2 mm and 10 mm, and the rocker has a thickness between 3 mm and 10 mm.

8. The bread cutting machine according to claim 7 , wherein the cover plate has a thickness of 3 mm, and the rocker has a thickness of 6 mm.

9. The bread cutting machine according to claim 1 , wherein the cover plate or the rocker are made of plastic.

10. The bread cutting machine according to claim 1 , wherein the rocker has continuous recesses which are arranged in the region of the rocker with which the rocker is mounted below the cuttable material during cutting operation.

11. The bread cutting machine according to claim 10 , wherein the carriage has openings which at least partially overlap with the continuous recesses of the rocker.

12. The bread cutting machine according to claim 1 , wherein the rocker is displaceable along rails orthogonally to the movement direction of the circular blade.

13. The bread cutting machine according to claim 1 , wherein the circular blade projects in the direction of the guide gap up to the height of the cover plate.
