Abstract: A method for cutting natural hides, on cutting machines comprising a conveyor belt on which a hide to be cut is arranged, and at least one longitudinal cantilever arm for supporting a cutting head, comprising the steps of: on a conveyor belt of the machine that is divided into a placement area, a cutting area and a collection area, wherein the collection area is an area of the conveyor belt toward which the at least one supporting arm protrudes with the corresponding cutting head, placing a hide on the placement area; defining a cutting layout on the hide; advancing the hide at the cutting area; by means of a collection operator, located at the collection area and directed toward the supporting arm with corresponding cutting head, rearranging the hide when it is at the cutting area; advancing the hide toward the collection area and collecting the cut pieces.

Abstract: A strip support and alignment device, particularly for strips to be cut in a cutting machine, the device comprising: a sheet that is stretched between a station for feeding at least one strip and a station for processing said strip, which defines a support and alignment surface for the strip, first elements for fixing the sheet to the feeding station, second elements for fixing the sheet to the processing station, elements for winding and unwinding the sheet, which are adapted to wind or unwind the sheet in order to vary its length depending on the distance between the feeding station and the processing station.

Abstract: An unrolling device, particularly for materials in rolls, with material alignment control, comprising elements for unrolling a roll of material to be unrolled, the device further comprising elements for detecting at least one lateral edge of the material unrolled from the roll which are adapted to detect quantitatively the movement of the edge transversely to the unrolling direction of the material.

Abstract: A method for detecting the position of a conveyor, comprising the steps of: providing on the conveyor belt an irregular marking, constituted by marks and the like that are detectable optically; by means of a vision device, detecting portions of the marking at preset time intervals; comparing a detection performed by the vision device with a previously performed detection, in order to determine the extent and direction of the movement.

Abstract: A device for retaining multilayer synthetic materials on cutting tables, comprising a supporting element adapted to be placed laterally to a multilayer to be processed, on a cutting table, and adapted to support a plate-like element whose dimensions are such as to protrude with respect to the supporting element and surmount the edge of the multilayer, the plate-like element passing from an inactive configuration to an active configuration in which the plate-like element is pressed with its edge against the edge of the multilayer.
