Claims
- 1. Device (1) for slicing loaves and other bakery products, comprising a frame (2), which is provided with support means (4,5) for the loaves (7), the support means define a path for the loaves through the device, a cutting-blade carrier (10), which holds a plurality of thin, elongate cutting blades (11) having a longitudinal direction and coming into contact with the loaves (7) over a length thereof defining a bread-contacting length of the cutting blades (11), the cutting blades (11) being next to one another and at a distance from one another, each cutting blade having a cutting edge (13) which has cutting formations for cutting the loaves, drive means for creating a reciprocating movement of the cutting blades with respect to the support means (4,5) for the loaves, which reciprocating movement is parallel to the longitudinal direction of the cutting blades, the drive means of the cutting-blade carrier providing a first movement, defining a first amplitude in the longitudinal direction of the cutting blades (11) and a first frequency, and also provide a second movement, defining a second amplitude in the longitudinal direction of the cutting blades and a second frequency, the first amplitude being greater than the second amplitude and the first frequency being lower than the second frequency, and in that the drive means are designed to superimpose the first movement and the second movement to form a resultant movement, and in that the drive means drive the cutting blades (11) with the resultant movement, and a cleaning means (70,71), which clean the cutting blades during the cutting of the loaves, the cleaning means are disposed outside the path for the loaves (7) which is defined by the support means (4,5), and wherein the first amplitude is such that the bread-contacting length of the cutting blades (11) substantially pass over the cleaning means (70,71) while other portions of the cutting blades (11) different from the bread-contacting length do not substantially pass over the cleaning means (70,71).
- 2. Device according to claim 1, in which the first amplitude lies in the order of magnitude of a few centimeters and the second amplitude lies in the order of magnitude of up to several millimeters, in which the first frequency lies in the order of magnitude of one or more strokes per second and the second frequency lies in the order of magnitude of at least several tens of strokes per second.
- 3. Device according to claim 1, in which each of the cutting blades (11) is provided on the cutting edge (13) with cutting formations situated at regular distances from one another, the distance between adjacent cutting formations lying between 0.5 and 4 millimeters.
- 4. Device according to claim 1, in which the first movement is a substantially rectilinear, reciprocating movement, and in which the second movement is a loop movement, as seen in a plane defined by the longitudinal direction of a cutting blade (11), on the one hand, and the path for the loaves through the device, on the other hand.
- 5. Device according to claim 4, in which the loop movement defines an arc path from a top point situated furthest away from the support means towards a bottom point situated closest to the support means, with a first deviation with respect to the imaginary straight line between a top point and a bottom point, which first deviation is directed counter to the passage direction, and in which the loop movement also defines an arc path from the bottom point to the top point, with a second deviation with respect to an imaginary straight line between the bottom point and the top point, which second deviation is likewise directed counter to the passage direction, and in which the first deviation is greater than the second deviation.
- 6. Device according to claim 1, in which the drive means for the cutting-blade carrier comprise an intermediate carrier (41,42), which is disposed between the frame (2) and the cutting-blade carrier (10), in which the intermediate carrier (41,42) is held in the frame (2) such that movement is permitted in a reciprocating manner substantially parallel to the longitudinal direction of the cutting blades, and in which the. intermediate carrier is designed to support the cutting blades (11) such that movement is permitted with respect to the intermediate carrier, the drive means comprising first drive means (51,53,54,56), which are disposed between the frame and the intermediate carrier for driving the intermediate carrier such that the intermediate carrier moves with respect to the frame, and second drive means (65,67,68), which are disposed between the intermediate carrier and the cutting blades so as to drive the cutting blades for movement with respect to the intermediate carrier.
- 7. Device according to claim 6, in which the intermediate carrier (41,42) is guided such that movement is permitted in a substantially rectilinear (40), reciprocating manner in the frame, and in which the first drive means (51,53,54,56) create the first movement, and in which the second drive means (65,66,67,68) create the second movement.
- 8. Device according to claim 7, in which the second movement is a substantially circular movement.
