The known machines comprise one or more pairs of sizing rollers which are adapted to reduce the thickness of the rolled-out pasta coming from a rolling- out machine, up to a desired thickness. The rolled-out pasta thus obtained, called also"sheet", drops vertically, due to the gravity, inside a cutting device which provides to cut portions of rolled-out pasta, from which there will originate, thanks to suitable and subsequent following operations, the above mentioned products of pasta containing a savoury filling.

The cutting device comprises respective blanking dies with a substantially quadrangular shape having, each of them, two pairs of opposed and parallel perimetral sides, and arranged in such a manner that the longest diagonal results to be vertically oriented, practically substantially parallel to the advancement direction of the sheet of rolled-out pasta.

The alongside direction of the cut portions is perpendicular with regard to the advancement path of the sheet of rolled-out pasta. These arrangement causes remarkable inconveniences.

The need, for the following working steps, to have enough space between the various cut portions and the quadrangular shape of the same portions cause, with a standard width of the sheet of rolled-out pasta, a reduced number of cut portions and a relevant quantity of scrap in the sheet of rolled-out pasta which is not directly used in the formation of the final product. Said scrap is consequently used again, by adding same to novel fresh dough; practically, said scrap is cut into small pieces by suitable knives, and, through conveyor belts and suction devices, it is again inserted into the kneading machine so as to be amalgamated with the fresh dough existing at the interior of said kneading machine, with a consequent decrease of the elastic and qualitative properties of the final dough to be fed to the rolling-out device.

Therefore, the small number of cut portions which can be obtained, by cutting, in the width of the standard dimensions sheet, does not imply high levels of productivity.

Object of the present invention is to eliminate the above mentioned drawbacks by a machine for the treatment of rolled-out pasta which obtains a better production with the limitation of the quantity of scrap of the non-used rolled out pasta, maintaining the standard size of the width of the sheet.

According to the present invention there is provided a machine for the treatment of rolled-out pasta, particularly for the production of products of pasta containing a savoury filling, comprising feeding means for feeding a sheet of rolled-out pasta along a predetermined path of advancement, said sheet longitudinally developing according to said path, a working station, comprising cutting devices of said sheet of pasta, to obtain from the same shaped portions which are suitable for the realization of said products, said advancement means feeding said sheet to said working station, and said cutting devices being arranged the one following the other according to a predetermined side-by-side direction, characterised by the fact that said side-by-side direction is inclined with respect to said predetermined advancement path.

Advantageously, the inclination of the side-by-side direction of the cutting devices allows, maintaining the required operative spaces between the blanking dies, to operate cuttings close between them on the rolled-out pasta, improving in such manner the utilization of the surface of the same rolled-out pasta. Thanks to the inclination of their side-by-side directions, it is possible to arrange a large number of cutting devices suitable to act simultaneously, so the number of cut portions obtained is greater with a great reduction of the working times.

The technical features of the invention, and the advantages deriving therefrom will appear evident from the following description which has been made with reference to the attached sheets of drawings, in which: - Figure 1 shows, in schematic view and frontal elevation and with omitted portions, a preferred embodiment of the machine for the treatment of the rolled-out pasta according to the present invention; - Figures 2 and 3 show, in schematic and section view, according to the line A-A of Figure 1, a particular of the machine of Figure 1, in two different phases of operation; - Figure 4 shows, in schematic view and frontal elevation, a particular of the machine of Figure 1.

According to Figure 1, the machine 1 comprises a base 20 and a frame 21. Furthermore, the machine 1 comprises two counter-rotating sizing rollers 2 and 3, respectively upper and lower, between which there is caused to pass a sheet 4 of rolled-out pasta in order to reduce its thickness to an established value.

The sheet 4 of rolled-out pasta is fed to the rollers 2 and 3 by a feeding station of known type (not illustrated).

According to Figures 2 and 3, the sheet 4 of rolled-out pasta is guided, as it comes out from the cited rollers 2 and 3, by a first lower blade 5 which also facilitates the detachment of the same sheet 4 from the lower sizing roller 3.

The machine 1 also comprises a second upper blade 6 which engages the surface of the upper sizing roller 2 in order to detach from this latter possible residual portions of pasta.

The two blades 5,6 are fulcrumed on respective pins 7,8 and are elastically connected between each other by means of a helical spring 9 which causes the said blades 5,6 to adhere against the outer surface of the sizing rollers 2,3.

With reference to Figures 2,3, arranged below said sizing rollers 2,3, the machine 1 comprises a couple of inclined plates 10,11, suitable to facilitate the passing of the sheet 4 of rolled-out pasta through a working station 17 comprising a shearing device 13 provided with a plurality of shaped blanking dies 12.

Each of blanking dies 12, one of which is shown in Figure 3 in an advanced configuration, is suitable to cut a respective portion 16 of the sheet 4 of rolled-out pasta, which portion 16 is proportionate to the desired dimension of the finished product of required pasta containing a savoury filling.

The mentioned portion 16 is then pushed by a rod 14 through a forming unit 15 and then machined according known procedures (not described).

According to which is described in Figure 1, the working station 17 and the forming unit 15 are supported by the frame 21 and arranged inclined with <BR> <BR> respect to the path P of the sheet 4 of rolled-out pasta; i. e. , the side-by-side direction F of the portions 16, with the respective blanking dies 12, and the advancement path P of the rolled-out sheet 4, form an angle between them, and said angles are different from 90°.

Maintaining unaltered the side-by-side distance of the portions 16 of the known machines, the inclined disposition of the forming unit 15 and the consequent inclination of the blanking device 13 with the respective blanking dies 12, improves the blanking of the portions 16 of the rolled-out sheet 4. In fact, the mentioned shaped blanking dies 12 have a substantially quadrangular shape and have each two pairs of parallel, opposite perimetral sides, as illustrated in Figure 4, where there is shown the empty space 18 created after the cutting of the blanking dies 12, which correspond exactly to the shape of the portion 16 of rolled-out pasta.

By arranging the sides of one of said pairs oriented parallel to the advancement path P of the sheet 4, the scrap of rolled-out pasta between an empty space 18 and the other, due to the edges between the blanking dies 12, is minimum. There follows that the portion of the sheet 4 which, after the cutting, is sent toward a scrap-cutting unit 19 and on its turn sent, by suction means or belt conveyors, to the kneading machine so as to be amalgamated with the fresh dough, because of its small quantity does not compromise the elastic and qualitative properties of the final dough.
