DETAILED DESCRIPTION OF THE INVENTION

[0033] With reference to the Figures, a cutting support according to the invention is described, which is indicated with reference number 100.

[0034] FIG. 6 illustrates a cutting machine (M) of bridge type provided with cutting means (64). Advantageously, the cutting means (64) are a vertically arranged cutting disc. The cutting machine (M) includes the cutting support (100) mounted on a work surface (60) arranged under the cutting means (64).

[0035] Referring to FIGS. 1 and 2, the cutting support (100) is suitable for supporting a strip (9) of stone material, such as granite, marble or stone. The strip (9) is cut in such a way to obtain a slab with lower thickness than the initial strip.

[0036] The term “strip” indicates a slab-like element having a much greater length than the height and a much lower thickness than the height.

[0037] The strip (9) has a lower edge, an upper edge, two lateral sides, a front edge and a back edge. The strip (9) is arranged with the lower edge on the cutting support (100).

[0038] The cutting support (100) includes a frame (1) and retention means (2).

[0039] The frame (1) has an L-shaped cross section. The frame (1) includes a horizontal element (10) and a vertical element (11). The lower edge of the strip (9) faces the horizontal element (10) of the frame in such a way that a lateral side of the strip (9) faces the vertical element (11) of the frame.

[0040] The retention means (2) are arranged on the vertical element (11). The retention means (2) are suitable for holding the strip (9) toward the vertical element (11) of the frame.

[0041] The retention means (2) comprise at least one suction cup means (20) of pneumatic type disposed on the vertical element (11) of the frame (1) and suitable for retaining the strip (9) by creating a vacuum.

[0042] Said suction cup means (20) may include traditional suction cups comprising membranes disposed in seats of the vertical element of the frame. Pneumatic connection means (G) are connected to the suction cup means (20). The pneumatic connection means (G) are suitable for being connected to a suction device so as to create an air vacuum between the suction cup means (20) and the strip (9).

[0043] Each suction cup means (20) includes a through hole (23) arranged in the vertical element of the frame and an annular seal (25) arranged around the through hole (23). The through hole (23) is connected to the pneumatic connection means (G) for creating a vacuum that attracts the strip so that the annular seal (25) is compressed by the strip (9).

[0044] The cutting support (100) includes a sacrificial panel (4) arranged above the horizontal element (10) of the frame in such a way that the strip (9) is arranged on the sacrificial panel (4). In this way, when cutting the strip (9), the cutting disc touches the sacrificial panel (4), protecting the horizontal element (10) of the frame.

[0045] Referring to FIGS. 3, 4 and 5, the cutting support (100) also includes a stop panel (3) arranged alongside the vertical element (11) of the frame.

[0046] The stop panel (3) includes an inner face facing the vertical element (11) of the frame and an outer surface (30) facing a lateral side of the strip (9). In such a case, the retention means (2) comprise suction cup means (20) arranged on the outer surface (30) of the stop panel (3). Each suction cup means includes a through hole (27) obtained in the stop panel and communicating with a through hole (23) obtained in the vertical element (11) of the frame and an annular seal (25) arranged on the outer surface (30) of the stop panel around the through hole (27) of the stop panel. The pneumatic connection means (G) are connected to the suction cup means, that is to say, they are connected to the through holes (23, 27) of the vertical element and of the stop panel.

[0047] Referring to FIG. 4, the pneumatic connection means (G) comprise a duct (7), in which the air sucked by the suction device is conveyed, and solenoid valves (8) at each through hole (23) of the vertical element of the cutting support. The solenoid valves (8) can be selectively opened or closed to enable the operation of the suction cup means (20) according to the length of the strip (9) to be cut.

[0048] Each solenoid valve (8) communicates with a conduit communicating with the through hole (23) obtained in the vertical element (11) of the frame and consequently with the through hole (27) obtained in the stop panel (3). The solenoid valves (8) are located behind the vertical element (11) of the frame (1) and are connected in series via the conduit (7).

[0049] With reference to FIGS. 4 and 5, the cutting support (100) includes an adjustment unit (5) to adjust the inclination of the stop panel (3) relative to the vertical element (11) of the frame (1). The adjustment unit (5) may include a plurality of adjustment screws (50).

[0050] Referring to FIG. 6, the cutting machine (M) includes an operating head (62) that supports the cutting means (64) above the work surface (60) on which the cutting support (100) is mounted. Handling means (63) move the operating head (62) relative to the work surface (60) or vice versa.

[0051] The operating head (62) is moved vertically by an actuator arranged in a carriage (69) moved by an overhead system (65) along two orthogonal axes. The carriage (69) is slidingly mounted on a beam (67). The beam (67) is slidingly mounted on two crossbeams (68) supported by sides (66) of the machine.

[0052] Obviously, the handling means (63) can be connected to the work surface (60) in order to move the work surface with respect to the cutting means (64).

[0053] Following is a description of the operation of the cutting machine (M). In order to cut the strip (9) and obtain a skirting board, the strip (9) is placed on the cutting support (100) in such a way that it can be cut into two layers with preset thickness.

[0054] The retention means (2) are activated as soon as the strip (9) is placed on the sacrificial panel (4), creating an air vacuum between the strip (9) and the outer surface (30) of the stop panel (3) defined by the seal (25), in such a way that the strip (9) is retained on the seal (25).

[0055] The retention means (2) enable the strip (9) to be retained on the outer surface (30) of the stop panel (3) without interfering with the cutting means (64).

[0056] In order to make the cut, the handling means (63) move the cutting means (64), bringing them closer to the strip (9) positioned on the cutting support (100), along a direction perpendicular to the sacrificial panel (4).

[0057] The retention means (2) are deactivated as soon as the strip (9) is cut, the retention means (2) in such a way to release a portion of the strip with the preset thickness.

[0058] The advantages of the cutting support (100) according to the invention appear obvious because it provides for facilitating the cutting of the strip (9) to reduce its thickness. In this way, rejected slabs from the previous flooring operations can be used in a way that reduces waste.

[0059] Although the present invention originates from the idea of recovering the rejected slabs from flooring operations, the cutting machine (M) provided with the cutting support (100) can cut any type of slab.

[0060] Numerous variations and modifications can be made to the present embodiment of the invention, within the reach of a person skilled in the art, but still within the scope of the invention as expressed by the appended claims.
