Abstract: A modular comb element for a machine for automatically cutting a mat of sheets of material. The cutting machine includes a plurality of cutting supports. The comb element includes a plate forming a support from which a first and a second row of teeth extend longitudinally. The teeth of the first row alternate with the teeth of the second row, and a free end of the teeth of the first row are farther from a downstream edge of the support than a free end of the teeth of the second row of teeth. A ramp is mounted on the downstream edge of the support and inclined with respect to the latter so as to limit the contact surface between the mat of sheets and the comb element. Air injection means are at a downstream edge of the ramp over an entire width thereof.

Abstract: A suction cutting conveyor of an automatic blade cutting machine for sheet materials, including a plurality of cutting supports rigidly connected to a drive mechanism driven along rectilinear and curvilinear trajectories, each cutting support including a plurality of bristles each having a foot rigidly connected to a sole and a head opposite to the foot and on which a sheet material to be cut is intended to rest, the sole of each cutting support being capable of being able to elastically deform following the trajectories of the drive mechanism.

Abstract: A modular cutting-support element with suction in a machine for automatic cutting of sheet material by means of blades, includes a plurality of bristles arranged in the same single line, at least some of the bristles each having a base rigidly connected to a bearing plate intended to be mounted on a support, a head opposite the base on which a sheet material to be cut is intended to rest, and a stem connecting the head to the base, the largest cross-section of which is strictly included in the largest cross-section of the head, the bearing plate comprising, on each of its side surfaces, a plurality of transverse channels for the passage of suction air providing communication between an upper surface of the bearing plate from which the bristles extend and an inner surface opposite the upper surface.

Abstract: The invention relates to a machine for automatically cutting sheet material, the machine comprising a bench having a cutting zone, a cutter head mounted on means for moving it relative to the bundle, a cutter conveyor housed inside a box placed under the cutting zone, and means for establishing suction in the box, the box bulging outwards at least in its bottom portion that is remote from the cutting zone.

Abstract: Pieces (21) are cut out from a lay-up (20) built up from plies of superposed flexible sheets of material, and the lay-up is then packaged in full inside a covering (70) without separating the cutout pieces from the scrap. The lay-up can thus be transferred from a cutting installation to a workshop for assembling the pieces, and information relating to the layout or layouts of the cutout pieces can be transmitted therewith.

Abstract: The invention provides apparatus for reducing the working area for cutting on a cutting machine for cutting a stack (1) of sheet material, the machine being provided with an automatic moving cutting tool (4) and with suction apparatus for holding the stack covered in air-impervious film (5) down on a cutting table (3) having a conveyorized support surface 3a. The apparatus comprises the air-impervious film (5) for covering the stack (1), an air-impervious movable mask loop (6) designed to cover a portion of the table (3), and a low friction block (65) for positioning the mask (6) over the portion of the table. The mask (6) covers the portion of the table and holds down the film (5) and the mask (6) when suction is applied beneath the table. The mask (6) is able to move across the portion of the table when a conveyor (62) transfers the stack (1) by use of the conveyorized support surface 3a.

Abstract: The invention relates to an installation for automatically cutting sheet material, the installation comprising at least one cutting device and at least one device for stacking sheets for cutting. The cutting device comprises a bench, and a cutting head mounted on displacement means. From its feed end to its unloading end, the bench has a cutting zone beneath which a suction cutting conveyor is mounted together with an unloading conveyor. Turbine means for creating suction are disposed beneath the unloading conveyor, and the cutting head is mounted on the face of the displacement means that face toward the feed end of the bench.

Abstract: The invention provides apparatus for reducing the working area for cutting on a cutting machine The apparatus comprises the cutting machine made up of a cutting table, the working area on the surface of the cutting table, an automatic cutting tool for cutting a stack of sheet material within the working area and a suction apparatus providing suction to the working area. An air-impervious film covers the stack and which holds the stack down within the working area when suction is applied. An air-impervious removable mask (6) covers a portion of the working area and is held in a determined position by fixing and positioning structures, such as a strip and an abutment attached to the mask. When the mask is held in the determined position, the working area is effectively reduced to a portion of the working area that is not covered by the mask.

Abstract: The invention relates to a suction device for holding a stack of sheet material on a cutting table (A) of an automatic cutting machine. The suction device comprises a turbine (4) provided with a suction air inlet circuit (41) level with the cutting zone to establish suction for the purpose of holding the stack on the table, and with an air exhaust circuit (40), the turbine being driven by an electric motor (5) having a fan (15) and an air outlet duct (50), the electric drive motor (5) may vary its speed of rotation to adjust the amount of suction.

Abstract: The invention relates to an electrical connection device with automatic positioning. The device comprises a first moving carriage (44) displaceable in a connection direction (C); a second carriage (48) mounted on the first carriage and movable relative thereto in a direction orthogonal to the connection direction (C); an indexer element (64) secured to the second carriage extending along the connection direction, the first connection element (34) being secured to the second carriage; and a stationary assembly forming a cam (72) for the indexer element, the second connection element being secured to the cam-forming assembly.
