Abstract: An automatic machine and an automatic method for grinding the perimetric edge of rectangular or nonrectangular of glass sheets arranged substantially vertically, comprising at least one conveyor and at least one workhead provided with an abrasive tool for grinding the glass sheet at its edge, following its perimetric profile by way of the relative action of movement of the glass sheet and movement of the at least one workhead. During grinding, the glass sheet is no longer supported and moved by the conveyor but by at least one carriage, to which the glass sheet is coupled by way of at least one sucker.

Abstract: An automatic machine for versatile and alternative application of at least two types of sealant along the perimetric rim of an insulating glazing unit, whose spacer frame is constituted preferably but not exclusively by a continuous strip of expanded synthetic material. In particular, the machine allows simple and quick switching from one sealant to another, since the path of the plurality of sealants which starts from their feed, be they of the hot and/or cold extruded type, uses a plurality of ducts which reach the extrusion nozzles that are active proximate to the perimetric rim of the insulating glazing unit.

Abstract: An automatic device for perimetric sealing of an insulating glazing unit composed of at least two glass panes and at least one spacer frame supported and movable in a slightly inclined position with respect to the vertical on a conveyor. A sealing head movable with relative motion with respect to the glazing unit has at least one sealing nozzle suitable to deliver a sealant flow. In order to maintain the correct mutual position of said at least one sealing nozzle with respect to the cavities of the glazing unit to be sealed and to allow the spacing of the nozzle therefrom, a sensor is provided transversely to the plane of the insulating glazing unit that detects the distance from the glass pane. An actuation mechanism is further provided for the relative motion between the sealing head and nozzle and the glazing unit.

Abstract: An automatic machine for arrissing the edges of glass sheets, comprising devices that allow to work glass sheets by way of rigid tools, such as diamond grinding wheels, by acting simultaneously on the two face edges along the perimeter of the sheet. The machine comprises at least one working head, provided with a tool with a probe and feedback circuits for grinding symmetrically the glass sheet and following the perimetric profile of the sheet by a combined action of moving the glass sheet and at least one working head.

Abstract: An automatic machine and an automatic method for the application of a spacer profile, preferably made of expanded synthetic material, on a glass sheet in order to compose the insulating glazing unit, after extrusion of a thermoplastic sealant on a portion of each one of its faces designed for mating. The process for extrusion of the sealant on the profile is independent of the process for applying the profile on the glass sheet, so that therefore each one of the two processes can be performed by using its optimum parameters.

Abstract: A device and a method for filling with a gas other than air an insulating glazing unit composed of at least two glass panes and at least one spacer frame, comprising a movable and a fixed bed. The fixed bed is provided with retractable suckers suitable to capture a lower flap of a glass pane and move therewith with a motion of retraction with respect to the movable bed, such as to provide straightening of the lower flap of the glass pane.

Abstract: An automatic machine and a related method for grinding the arrises of glass panes, provided with devices which allow to work glass panes which are rectangular or optionally contoured, at the arrises thereof, with rigid tools, such as diamond grinding wheels, by acting simultaneously but independently on the two mutually opposite arrises along the perimeter of the pane. The machine has at least one pair of mutually opposite working heads, each working head being provided with a tool which can be moved by floating toward the arris of the glass pane which is independent of the approach of the opposite tool. By way of the combined action of movement of the glass pane and of at least one pair of working heads it is also possible to work glass panes which have a nonrectangular shape.

Abstract: An automatic machine for applying a flexible tape on a substantially flat glass pane, comprising a machine body in which there is a plane for the substantially vertical arrangement of at least one substantially flat glass pane, a carriage with which a head for applying a flexible tape along the perimetric edge of the glass pane is associated, and tape feeder means rigidly coupled to the application head, the glass pane and the carriage being mutually movable with a translational motion along at least one first axis and one second axis, which are mutually substantially perpendicular and parallel to the plane of arrangement.

Abstract: An automatic machine for grinding the borders of glass panes, particularly the edges, arranged preferably vertically but applicable to any other arrangement, comprising devices which allow the machining of glass panes, which are notoriously fragile and have an irregularly cut or even contoured perimeter by means of a rigid tool, such as a diamond grinding wheel, by acting simultaneously on the two edges along the perimeter of the pane. In particular, the machine comprises a feeler element and feedback circuits for symmetrically edging the glasspane and, advantageously, for keeping unchanged the perimetric profile of the pane.

Abstract: The present invention relates to an automatic machine and an automated procedure for the extrusion and application of sealant onto the lateral walls of a spacer frame for insulating glass, mainly of rectangular shape yet not ruling out shapes differing from rectangular with the introduction of a specific option. An essential feature of the machine consists in that the “spacer frame”, which always results as being suspended, requires neither resting nor running bases and therefore the surfaces which have been spread with sealant will never be contaminated by any other agent.

The tool is of the cup-shaped type and has an active flat surface for treating the coatings. The tool is contacting the glass plate coating on an annular portion of the flat surface thereof.

Abstract: An automatic method and device for filling, with gases other than air, insulating glazing units. The method entailing a step for injecting the gas and expelling the air so as to produce a laminar flow through a manifold constituted by the hollow region of the profile that forms the spacer frame. The method and the device allow a considerable saving in costs, reducing the amount of gas required for filling to an amount very close to the volume of the inner space provided in the insulating glazing unit.
