The assembling step is a step of preparing an assembly. The setting step is a step of setting a plurality of holder installation areas along an outer peripheral edge of the peripheral wall. The determining step is a step of determining a first area in which the slit and the peripheral wall are not adjacent to each other in the first area and a second area in which the slit and the peripheral wall are adjacent to each other. The installation step is a step of providing a holder in the first area without providing the holder in the second area.

A high speed parallel manufacturing line for manufacturing insulated glass units, the manufacturing line including a gas filling topping press that mates a spacer applied lite supplied to the topping press and a topping lite supplied to the topping press to create an insulated glass unit and fills the insulated glass unit with a non-air gas. A heating station applies localized heat to adhesive of the spacer material. A sealing press applies pressure to the insulated glass unit and facilitates further sealing of the spacer material to the spacer applied lite and the topping lite. The line may include a fourth corner sealer that completes sealing of the airspace of the IGU prior to finishing of the IGU.

An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material. Before the metal material filling the second corner C is solidified, the second metal introduction device 5B is moved from the second corner C toward another end of another third side Vbc, while performing filling with a metal material.

Provided is a vacuum insulation glass panel assembly manufacturing method and apparatus. The vacuum insulation glass panel assembly manufacturing method includes an edge sealing step of sealing an edge of a glass panel assembly of glass panels spaced apart at a predetermined interval, and an exhaust port sealing step of causing a lid member to seal an exhaust port of the glass panel assembly formed so as to communicate with a space between the glass panels whose edges are sealed. A glass solder having a high melting point is used in the edge sealing step, and a glass solder having a low melting point is used in the exhaust port sealing step. A specially designed lid member closing device is used for exhaust port sealing.

An automatic device and an automatic method for filling with gas other than air the insulating glazing unit composed of at least two glass panes and at least one spacer frame. The device comprises mechanisms for flattening the glass panes when they are not sufficiently flat, for example in the case of laminated or tempered panes. This allows to perform in an optimum manner the filling with gas and to process insulating glazing units with special spacer frames.

Embodiments include a method for replacing air with an interpane gas during manufacture of a sealed insulating glass unit (IGU). The method includes forming an unsealed IGU assembly defining an IGU passage for fluid communication between an interpane space and an ambient environment; positioning the unsealed IGU assembly within an enclosure and sealing the enclosure around the unsealed IGU assembly; evacuating air from the enclosure; introducing a first gas into the interpane space through the IGU passage; introducing a second gas into the enclosure, wherein the second gas has a different composition than the first gas; and closing the IGU passage to seal the interpane space. Other embodiments are also included herein.

An assembly press for producing an insulating glass element with two panes includes: two press elements arranged opposite each other with a working chamber defined by a spacing therebetween, the spacing being adjustable in a first direction to press together the panes; and a conveying device to transport the panes into and out of the working chamber in a second direction perpendicular to the first direction, at least one of the press elements being adjustable in a third direction perpendicular to the first and second directions. The conveying device comprises first and second drivable conveying elements respectively including first and second support mechanisms to respectively support lower faces of the two panes during transport in a first and second transport planes. The first and second conveying elements are adjustable independently of each other such that the transport planes are located at different positions in the third direction.
