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.

Abstract: The device for sharpening a cutting blade presenting a sharp edge includes at least one grinding wheel provided at least on the surface with abrasive material. The grinding wheel has a cylindrical body presenting a V-sectioned peripheral groove, and is mounted to rotate freely about an axis contained in a plane generally parallel to the sharp edge of the blade and perpendicular to the median plane of the blade, with the axis being inclined by a predetermined angle with respect to the normal to the median plane of the blade. The sharpening device is further constructed to place the blade and the grinding wheel in contact and to provide for relative displacement of the blade and the grinding wheel in a direction parallel to the sharp edge of the blade.

Abstract: The invention uses a carriage that is longitudinally displaceable with respect to a cutting table, and a light transporting band whose width is at least equal to that of the sheets. The carriage is comprised of two separable movable members, one of which is motorized and comprises an image device for recording an optimized disposition of pieces to be cut out, while the other is towed and comprises a transversal clamping device into which is engaged a free end of the sheet. The towed member is coupled at its rear portion to the light transporting band, the latter serving to support and protect the sheet of patterned material when it is being drawn out.

Abstract: An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

Abstract: This invention relates to a device for driving and displacing a beam in a direction parallel to guide rails, and one or more carriages rigid with the beam in a direction transverse to the displacement of the beam.The device comprises two cables 7 and 8 stretched over pulleys 5 fixed at the ends of the guide rails 3 for the beam 4, and over pulleys 6 of the beam 4. The cables 7 and 8 are wound in reverse directions on the drums 9 of the motors M 1 and M 2 which are disposed symmetrically on one and the other side of the rails, such that when the motors are rotated, they cause the displacement of the beam, or of the carriage fixed on to one of the cables, or the simultaneous displacement of the beam and carriage.
