Abstract

Abstract A process for manufacturing a glazing unit by jointing a metallized margin of a sheet of glass to an intervening spacer strip following a course along the peripheral margin of the unit, the joint between the sheet and the strip along at least a section of such course being formed by applying molten solder into the corner angle between the sheet and the strip to form a solder bead along the section, the joint being progressively traversed by at least one flame so that at each moment during its progress along the joint such flame acts on such solder metal before it has completely solidified whereby the final bead is formed by solidification of solder metal from the molten condition in which it is left by such flame and apparatus for carrying out such process.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 176 words
In a process for manufacturing a glazing unit by jointing a metallized margin of a sheet of glass to any intervening spacer strip following a course along the peripheral margin of the unit in which the joint between said sheet and said strip along at least a section of such course is formed by applying solder into the corner angle between said sheet and said strip to form a solder bead along said section, the improvement comprising the steps of progressively melting and spreading with a soldering iron solder metal along the joint angle and progressively transversing the joint by at least one finishing flame so that at each moment during its progress along the joint such finishing flame acts on such solder metal before it has completely solidified whereby a final bead is formed by solidification of solder metal from the molten condition in which it is left by such finishing flame, which bead has a curved surface which merges tangentially with the faces of the spacer strip and metallized margin defining the corner angle.
Claim 2
Dependent Claim 176 words
In a process for manufacturing a glazing unit by jointing a metallized margin of a sheet of glass to any intervening spacer strip following a course along the peripheral margin of the unit in which the joint between said sheet and said strip along at least a section of such course is formed by applying solder into the corner angle between said sheet and said strip to form a solder bead along said section, the improvement comprising the steps of progressively melting and spreading with a soldering iron solder metal along the joint angle and progressively transversing the joint by at least one finishing flame so that at each moment during its progress along the joint such finishing flame acts on such solder metal before it has completely solidified whereby a final bead is formed by solidification of solder metal from the molten condition in which it is left by such finishing flame, which bead has a curved surface which merges tangentially with the faces of the spacer strip and metallized margin defining the corner angle.
Claim 3
Dependent Claim 45 words
A process according to claim 1 characterized in that at each position along the joint line the solder metal is acted upon by at least one additional flame simultaneously with the contact by the soldering iron as well as subsequently by the first-mentioned finishing flame.
Claim 4
Dependent Claim 23 words
A process according to claim 1 characterized in that the finishing flame to which the solder metal is exposed is a reducing flame.
Claim 5
Dependent Claim 19 words
A process according to claim 1 characterized in that the solder bead is formed without using a soldering flux.
Claim 6
Dependent Claim 46 words
A process according to claim 1 characterized in that the sheet and spacer strip defining the corner angle are displaced parallel with the line of the joint and the source of supply of the solder metal and the source of the said finishing flame are fixed.
Claim 7
Dependent Claim 30 words
A process according to claim 1 characterized in that the soldering iron is displaced manually along the joint and said finishing flame is mechanically displaced and guided along the joint.
Claim 8
Dependent Claim 173 words
In a process for manufacturing a glazing unit by jointing a metallized margin of a sheet of glass to any intervening spacer strip following a course along the peripheral margin of the unit in which the joint between said sheet and said strip along at least a section of such course is formed by applying solder into the corner angle between said sheet and said strip to form a solder bead along said section, the improvement comprising the steps of progressively melting by induction heating solder metal along the joint angle and progressively transversing the joint by at least one finishing flame so that at each moment during its progress along the joint such finishing flame acts on such solder metal before it has completely solidified whereby a final bead is formed by solidification of solder metal from the molten condition in which it is left by such finishing flame, which bead has a curved surface which merges tangentially with the faces of the spacer strip and metallized margin defining the corner angle.
Claim 9
