A cutting apparatus includes a cut mechanism configured to cut a workpiece; and a control device configured to: judge whether or not each of plural patterns to be cut by the cut mechanism is a test pattern used for evaluating a cut quality of the workpiece cut by the cut mechanism; determine a cut sequence, the cut sequence indicating a sequence in which the plural patterns are cut from the workpiece by the cut mechanism, the cut sequence being determined so that a pattern judged as the test pattern is cut before a normal pattern judged to not be the test pattern; and control the cut mechanism to cut the plural patterns from the workpiece according to the cut sequence.

Device for controlling the sharpening state of a blade (2) having a cutting edge (20) delimited by two sides (21, 22) converging towards a plane (X) that contains the cutting edge itself. The device comprises two control surfaces each of which is in contact with a corresponding side (21, 22) of the cutting edge (20) and is connected with a transducer (R4), which produces an electrical displacement signal (S4) proportional to a displacement of the control surface with respect to said plane (X). Furthermore, the device comprises a processing unit (E) that receives said displacement signals (S4) and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. The control surfaces are the surfaces that delimit an external groove (40) of a roller (4) that is free to translate along an axis (A4) perpendicular to said plane (X) and spaced from the blade (2) by an amount such that said cutting edge (20) passes in said groove (40).

The device comprises two control surfaces each of which is in contact with a corresponding side (21, 22) of said cutting edge (20) and is connected with at least one transducer (R1, R2, R4), which produces an electrical displacement signal (S1, S2; S4) proportional to a displacement of the control surface with respect to said plane (X). Furthermore, the device comprises a processing unit (E) that receives said displacement signals (S1, S2, S4) and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. The processing unit is connected to means (101, 102) for supporting and moving sharpening means (100).

The invention relates to an automatic cutting device for printed graphic substrates. The device has a working plane configured to allow passage of a printed graphic substrate along a longitudinal direction (L) and a transverse cutting unit arranged at a slit of the working plane extending in a transverse direction (T) perpendicular to the longitudinal direction (L). The transverse cutting unit is movable along the slit in the transverse direction (T), and has a pair of uprights on which two pairs of counter-rotating blades are respectively mounted, the uprights being spaced apart in the longitudinal direction (L).

An apparatus for punching holes in posts in a transportation environment where the offset between the holes in the post and a vehicle running surface of a vehicle is constant over a transportation route. The apparatus has a frame and a hole forming assembly separate from one another, such that the hole forming assembly may be adjusted relative to the frame. The hole forming assembly can be adjusted relative to the frame and can be set at a specific offset between a location where the holes are to be formed in a post and the vehicle running surface. Once the offset is set, the apparatus maintains this offset for every post punched along the transportation route, so that there is a constant offset between the holes punched in the posts and the vehicle running surface.
