DETAILED DESCRIPTION OF THE INVENTION

[0040] A cutting machine 1 for cutting baguettes according to an embodiment of the invention is partially shown in FIGS. 1 to 3. The cutting machine 1 comprises a housing with an inlet (not shown) via which a baguette to be cut is inputted into the cutting machine 1. The cutting machine 1 comprises a receiving surface 10 by which the inserted baguette 2 is received. The receiving surface 10 has a first edge 11 and a second edge 12 opposite to the first edge 11. A cutting device 20 for cutting the baguette into a plurality of slices is provided at the second edge 12 of the receiving surface 10. The cutting machine 1 further comprises a pushing device 30 for pushing the baguette 2 to be cut along the receiving surface 10 in a pushing direction L extending between the first and second edges 11, 12 of the receiving surface 10, towards and beyond the cutting device 20. When the baguette 2 has been cut into the plurality of slices by means of the cutting device 20, the baguette slices, for example, fall into a funnel (not shown) which leads the baguette slices to a packaging bag (not shown). Upon completion of cutting the baguette 2 or when the packaging bag is completely filled, the packaging bag can be removed from the cutting machine 1.

[0041] The receiving surface 10 comprises a substantially flat receiving body 13 with a third edge 14 and a fourth edge 15 opposite to the third edge 14. A receiving plane R is defined by the flat receiving body 13. The receiving body 13 is provided with a number of grooves 16 which are extending from the second edge 12 towards the first edge 11 of the receiving body 13 and substantially parallel to the pushing direction L and to the third and fourth edges 14, 15. At the second edge 12, the receiving body 13 comprises a plurality of slits 17 also extending from the second edge 12 towards the first edge 11 of the receiving body 13 and substantially parallel to the pushing direction L. A guiding strip 18 is provided at the top surface of the receiving body 13, wherein the guiding strip 18 is attached near the third edge 14 of the receiving body 13 and extends between the first edge 11 and the second edge 12. The baguette 2 to be cut is placed against and guided by the guiding strip 18 during use.

[0042] The cutting device 20 comprises among others a first frame part 21 and a second frame part 22, which first and second frame parts 21, 22 are placed parallel to each other. Each of the first and second frame parts 21, 22 comprises securing members 23 in order to secure the cutting device 20 to the cutting machine 1. The cutting device 20 further comprises an array of cutting blades 24 which are provided between the first frame part 21 and the second frame part 22 and which are movable connected to the first and second frame parts 21, 22. The cutting blades 24 are movable in a cutting direction S and the array of cutting blades 24 defines a first plane C. Each of the cutting blades 24 is made of a thin elongated metal plate or strip with a cutting edge facing the pushing device 30, wherein each thin elongated metal plate or strip is substantially perpendicular to the first plane C. During use, the cutting blades 24 can be driven by means of a driving mechanism (not shown). As shown in FIG. 1, the cutting device 20 is provided at the second edge 12 of the receiving surface 10, wherein the cutting blades 24 are received by the slits 17. The cutting device 20 and the operation thereof as such are known and no further clarification of the cutting device 20 is considered necessary.

[0043] The pushing device 30 comprises a base part 31 which is placed above the top surface of the receiving surface 10. As shown in FIG. 3 the base part 31 extends over the complete width of the receiving surface 10. The base part 31 comprises a first coupling part 32 and a second coupling part 33, each provided with a coupling aperture 34. The pushing device 30, during use, is coupled to a driving mechanism (not shown) by means of the first coupling part 32 and the second coupling part 33, which might be the same driving mechanism as used for the cutting device 20. The driving mechanism drives the base part 31 and thus the baguette 2 towards the cutting device 20 along the pushing direction L when activated. As shown in FIG. 3 the base part 31 has a guide hole 35 which is configured for receiving the guiding strip 18 attached to the receiving surface 10.

[0044] As shown in FIGS. 1-3 the pushing device 30 further comprises a pushing member 36 defining a push surface P. The pushing member 36 has a hollow pushing body 37 which is provided with a number of slits 38, thereby defining a number of pushing fingers 39. The slits 38 are configured for receiving the cutting blades 24 of the cutting device 20 when the pushing device 30 pushes the baguette 2 beyond the cutting device 20. Each of the pushing fingers 39 has a contact part 40 which is in contact with the baguette 2 during pushing thereof. As shown in FIG. 3, each of the pushing fingers 39 has a length in the pushing direction L. As best shown in FIG. 3, the length of the pushing fingers 39 gradually decreases in a direction from the third edge 14 to the fourth edge 15. The push surface P defined by the pushing fingers 39, therefore, is at an acute angle with respect to the pushing direction L and at least as viewed in a direction substantially perpendicular to the receiving surface 10.

[0045] The angle between the push surface P and the pushing direction L can be between 5-25 degrees, in particular between 7-15 degrees, more particular can be about 10 or 11 degrees.

[0046] As shown in FIG. 2, the contact part 40 of each of the pushing fingers 39 is at an acute angle with respect to the receiving plane R defined by the receiving surface 10. The acute angle between the front parts 40 of the pushing fingers 39 and the receiving plane R gradually increases in a direction from the third edge 14 to the fourth edge 15. The baguette 2, therefore, becomes partially placed between the receiving surface 10 and at least a part of the pushing fingers 39 at least when being pushed, as shown in figure 3.

[0047] As shown in FIGS. 2 and 4, the pushing device 3 further comprises retaining members 41 which are secured to the hollow pushing body 37 and are extending from the hollow pushing body 37 towards the cutting device 20. Each of the retaining members 41 comprises a first part 42, which is configured to be received by one of the grooves 16 in the receiving body 13 and to be movable through the grooves 16. At the end of the first part 42 facing away from the hollow pushing body 37, a second part 43 is attached to the first part 42. As can be seen in FIGS. 2 and 4, the second part 43 is placed at an obtuse angle with respect to the first part 42 and to the receiving plane 3. The retaining members 41 define a retaining space for retaining the baguette 2 to be cut.

[0048] During use, the baguette 2 is inserted into the cutting machine 1 via the inlet in the housing and is guided towards the receiving surface 10. When the baguette 2 is received at the receiving surface 10, the baguette 2 is retained by the retaining members 41. Subsequently, the cutting device 20 and the pushing device 30 can be activated, such that the baguette 2 is pushed towards the cutting device 20. Upon reaching the cutting device 20, the baguette 2 is cut into multiple slices by pushing the baguette 2 beyond the cutting device 20.

[0049] It is to be understood that the above description is included to illustrate the operation of the preferred embodiments and is not meant to limit the scope of the invention. From the above discussion, many variations will be apparent to one skilled in the art that would yet be encompassed by the scope of the present invention.

[0050] In summary, the invention relates to a bread cutting machine for bread. The cutting device comprises: a receiving surface for receiving the bread to be cut, wherein said receiving surface has a first edge and an opposite second edge, and defines a receiving plane; a cutting device with an array of cutting blades placed at or near the first edge of the receiving surface, wherein said array of cutting blades defines a first plane; and a pushing device configured for pushing the bread to be cut along the receiving surface in a pushing direction extending between the first and second edges of the receiving surface, towards and/or beyond the cutting device. The pushing device comprises a push surface for contacting the bread to be cut during pushing thereof. The push surface and/or the first plane are at an acute angle with respect to the pushing direction.
