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 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.

Abstract: The device for removing coatings from the surface of a glass plate comprises at least one head which is movable along the rim portion of the glass plate, and at least one motorized tool provided at the head. 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.

Abstract: An automatic method and device for calendering aluminum profiles for producing spacer frames for insulating glazing units, the method consisting in producing calendering by preliminarily deforming the surface on which minute holes are formed so as to obtain an inside curve. A consecutive plurality of minute bends, the pitch increment whereof tends to zero and the bending angle increment whereof tends to zero, is then performed at an automatically controlled microbending station.

Abstract: Device for filling spacer frames for insulating glass with hygroscopic material, the frames comprising a first wall and a second wall that lie respectively outside and inside the insulating glass and two third side walls arranged adjacent to the glass sheets forming the insulating glass. The device comprises first means for forming at least one opening at the second inner wall of the frame and second means for inserting the hygroscopic material. There are also third means which seal the opening formed on the second inner wall.
