DESCRIPTIVE MEMORY FILED IN SUPPORT OF A PATENT INVENTION APPLICATION on behalf of the so-called company: S.A. IMMAFRO N.V. for:! I "Automatic bread cutting machine"

J

j - 1 - * The present invention relates to an improved automatic bread cutting machine.

Bread slicing machines usually have two parallel rectangular 5-blade holder frames actuated by a pendulum which alternately moves them in opposite directions in alternative translational movements. In the type of machine concerned by the invention, the bread to be cut is kept pressed against the cutting blades between a drive device 10 on which the bread rests and a bread press device which rests on top of the bread.

In known machines, the blade-holder frames and the bread press are fixedly mounted, making the machine suitable for cutting a type of bread into slices of a certain thickness.

The problem that the invention aims to solve is to make a machine which is suitable for cutting any type of bread, whatever its degree of tenderness, and which can easily cut the bread into 20 slices of different thicknesses.

This problem is solved by the invention which relates to an automatic bread cutting machine comprising blade-holder frames removably mounted in supports fixed to the machine casing and a bread press mounted on a support device. whose height position can be adjusted along a guide device attached to the box of ~ 2 - I the machine.

I The subject of the invention is also an automatic bread cutting machine which comprises a set of removable modular units, making the 5 modifications or repairs extremely easy and rapid.

The invention is set out in the following with reference to the accompanying drawings in which: - Figure 1 is a schematic perspective view 10 of a machine executed according to the invention; - Figure 2 is an elevational view of the support frame

Inement; - Figure 3 shows the device for adjusting the position of the bread press; FIGS. 4 and 5 show, respectively in elevation and in plan, the bread press; - Figure 6 shows the mounting of the cutting blade holder frames.

! Referring to FIG. 1, the box of the machine is designated by 1. The machine comprises two parallel blade-holder frames 2 actuated in a known manner by a pendulum mechanism housed inside the box 1 and not shown on the drawing. On the same side with respect to the blade holder frames 2 are arranged a bread drive unit 3 and a bread press 4. The unit

The drive 3 is shown on a larger scale in FIG. 2. It comprises a belt 31 stretched over two rollers 32, 33 and driven in scrolling by the rotation of the drive roller 32. The tension roller 33 is armed 30 by springs 34 and ensures the tension of the belt 31. jv 'The drive unit 3 is fixed by four screws 35 | on the side walls of the box 1.

i, the bread press 4 is mounted on a height adjustment device shown in particular in FIG. 3. The bread press 4 consists of a mat 4l stretched over two rollers 42 and 43 (Figures 4 and 5) · The bread press is fixed by lateral attachment tabs 51 to two support blocks 52 forming part of the height adjustment device. The blocks 52 are fixed to one end of the rods 53 connected to their lower end by a cross plate 54. The blocks 52 are also slidably mounted on columns 55.

The cross plate 54 is linked to a threaded rod 56 5 by means of a nut 57 and the threaded rod 56 is controlled by a geared motor 6. The rotation of the latter has the effect of vertically displacing the rods 53 and therefore the bread press 4. This can thus be placed in a position adjusted-suitably for the type of bread to be cut.

The mounting of the cutting blade holder frames * 2 is shown in particular in FIG. 6. The frames 2 carry, stretched between the opposite horizontal sides, a set of cutting blades 21 having a desired spacing 15 between them. Each frame is slid from above into slides 71 of a guide support 7 and is held there by threaded rods 8. Each blade holder frame can thus be easily removed for troubleshooting or to be replaced by another bearing frame cou-20 pantes blades having another spacing. The support 7 is connected to the pendulum action mechanism, known per se, of which the pendulum axis has simply been shown at 9- The crosspiece 72 is a stiffener. In operation, the two frames 2 are driven by reciprocating translational movements, the two frames being moved simultaneously in opposite directions, that is to say that a frame rises while the second frame descends.
