A cutting apparatus includes a rotatable holding table having a rectangular holding surface, a cutting unit having a cutting blade mounted to a rotatable spindle, and a sensor unit detecting a tip of the cutting blade entering between a light projection section and a light reception section. The sensor unit has an upper end located to be lower than a lower end of the holding table in a Z direction and is located below the axis of the spindle or an extension region of the axis, and when short sides of the rectangular holding surface are set parallel to a Y direction, an upper side of the sensor unit is opened to allow the cutting blade to enter between the light projection section and the light reception section.

An apparatus for cutting tires comprises a frame (1), an accommodation zone (2) intended to receive a tire (31) to be cut, lateral holding means (5, 6) for a tire, a detector (4) capable of detecting a central zone of a tire (31), blades (7) mounted to slide between a separated position of disengagement of the tread and a working position in which they penetrate into the sidewall (32) of a tire, and a control (9) ensuring that the blades (7) penetrate into the side walls (32) of the tire (31) only when they are above its tread (33). The lateral holding means (5, 6) comprise a vertically sliding jaw (6) capable of pressing against the bead (34) of a tire (31) and a part (5) with two branches (37) each bearing a wheel (38) capable of coming into contact with an inner surface (35) of the tread (33) of a tire, the jaw (6) and the part (5) being diametrically opposed relative to the inner circumference of a tire. The blades (7), when they are in working position, penetrate into the side walls (32) of a tire (31) received between the two branches (37) so as to stabilize the cutting zone.

A combination printer and cutting device for printing upon and cutting a web of media or tag stock into individual units. The device may cut vinyl, plastic, or RFID stock material as it moves through the printer in both back and forth directions. The device comprises a printer and a cutting apparatus that is further comprised of a carriage assembly and a movable cutter assembly. The cutter assembly is easily interchangeable and comprises a cutting element such as a wheel blade, and a pressure adjusting element for adjusting the amount of pressure applied by the cutting element to the stock material. Alternatively, the cutter assembly may be manufactured with a predetermined pressure load, but still permit an operator to adjust the depth of cut. The cutting apparatus is adaptable for use with both new and existing printers.

A machine for the working of sheet materials is described, which includes a support frame, a supporting head, a working means with rotary tools and a waterjet cutting tool. The machine is provided with fast-couplers that include first and second male fast-couplers respectively disposed on the working means with rotary tools and on the waterjet cutting tool, and first and second female fast-couplers disposed in the supporting head. The female fast-couplers are configured in such a way to permit the alternative coupling with the first male fast-coupler or with the second male fast-coupler.

The food slicer comprises a first support module for supporting at least one slicing blade, a second support module for supporting at least one piece of food and a drive mechanism means for transforming a relative movement of the first and second support modules into a movement of the slicing blade in the first support module, said relative movement involving a change in the height (h) between the first and second support modules. The slicing blade has a protruding portion protruding from at least one surface of the slicing blade in accordance with at least one ramp oriented to facilitate separation of the sliced piece of food from the rest of the piece of food without damaging it.
