Abstract: Operating head, specifically for laser machine, comprising: a base (12), a rotary body (20) fitted on the base (12) so to turn on an axis (B), a terminal body (30) mobile with respect to the rotary body (20) in the direction of said axis (B), a first motor (36) for controlling the movement of the rotary body (20) on said axis (B) and a second motor (42) for controlling the movement of the terminal body (30) on said axis (B). The first motor (36) and the second motor (42) are direct motors.

Abstract: A process and apparatus for cutting sheets of plastic material takes place upon a mobile support, such as a pallet. The pallets is centered for the cutting of the material and for the removal thereof in an assembly zone integral with a production line in which the materials of laminate glass are assembled. The pallet passes along a closed circuitous route, preferably in the presence of a plurality of similar pallets.

Abstract: The invention pertains to a process and device for the gripping at a storage station, transfer and placement of a sheet of flexible plastic material at the stacking station in an automatic production process for compound structures, especially compound panes. In accordance with the process, the sheet made of flexible plastic material is grasped by suction connected to a swinging stamp, first exerting suction on the median part of the sheet, while extending this suction progressively up to one end of the sheet, then by swinging back, extending said suction over the entire surface thereof, while the sheet is simultaneously placed flush on its support, generally the subjacent sheet.

Abstract: An automatic routing device for sheets made of plastic material utilized especially in compound panes has a cutting head with a band having a sharp edge in the form of a band saw blade. The cutting head is mounted to a structure allowing the cutting head to move along three orthogonal cartesian axes and to rotate along two orthogonal rotation axes. An electronic and numeric command and control device is provided to control the head.

Abstract: A laser cutting machine consisting of a focusing head; an exit nozzle; a joint structure which supports the head; a control unit; a drive device, which is supported by a joint structure and controlled by a control unit to move the head along a specified path in space, whereby a theoretically determined, invariant distance is maintained between the exit nozzle and a plate material to be cut, the head having first and second portions which can move relative to each other in the axial direction; a servomechanism, one end of the portions being coupled to the nozzle and a focusing lens, whereby while the machine is in use, the servomechanism controls the relative motion of the two portions in the axial direction independently of the control unit to maintain a specified and invariant distance between the nozzle and the surface.

Abstract: A machine (1) (53) (75) for effecting the transfer of objects in the space between positions having predetermined co-ordinates, in which said objects are supported by a head (25) integral with a pinion (20) (60) mounted rotatable on a slide (12a) (59) sliding in a direction perpendicular to the axis of said pinion (20) (60); the pinion (20) (60) meshing by opposing means with teeth (21) (64, 65) (76, 77) extending along said slide (12a) (59) and axially moving under the bias of driving apparatus (41, 42) (68, 69).

Abstract: The present invention relates to a focusing head 1 for a laser-beam cutting machine on which the head is designed to turn, in relation to the machine structure 4, around two axes combining to form an angle, the head consisting of two portions 15, 24 one of which 24 is provided with an output nozzle 43 and a focusing lens 42 and moves axially in relation to the other by means of a servomechanism 49 controlled by a position sensor 46 in sliding contact with the sheet material 3 being cut, the sensor 46 being tubular, being assembled in sliding manner on to the end of the nozzle 43 and constituting a guide for a cover gas.
