Abstract
Insulating glass is produced by forming an assembly having at least two facing glass sheets and at least one inner spacer frame separating the glass sheets, and by depositing a bead of sealant on an outer peripheral edge of the assembly; the sealant being deposited by keeping the assembly stationary in a vertical position, and moving a dispenser head along an endless path about the assembly; the dispenser head being moved about the assembly by resting at least one glass sheet on underlying movable supporting members, detaching the supporting members successively from the assembly to let the dispenser head through, and moving the supporting members back onto the assembly once the dispenser head has passed.
Claims12
1) A method of producing insulating glass, the method comprising the steps of forming an assembly comprising at least two facing glass sheets, and at least one inner spacer frame separating the glass sheets;
- keeping said assembly in a substantially vertical position;
- and depositing a bead of sealant on an outer peripheral edge of said assembly using a dispenser head;
- the method being characterized in that depositing said sealant comprises the steps of keeping said assembly stationary throughout the time taken to dispense said sealant;
- and moving said dispenser head along an endless path about said assembly;
- moving said dispenser head along said endless path comprising the steps of resting at least one of said glass sheets on movable supporting members underneath;
- detaching one or more of said supporting members successively from said assembly to let the dispenser head through;
- and moving at least some of said supporting members back onto said assembly once said dispenser head has passed.
6) A unit for producing insulating glass comprising an assembly, in turn comprising at least two facing glass sheets, at least one inner spacer frame separating said glass sheets, and a bead of sealant extending along an outer peripheral edge of said assembly;
- the unit comprising supporting means for supporting said assembly in a substantially vertical position;
- and a dispenser head for depositing said sealant and forming said bead;
- and the unit being characterized in that said supporting means support said assembly in a fixed position, and comprise a number of movable supporting members beneath at least one of said glass sheets;
- and powered actuating means for moving said supporting members to and from a supporting position supporting said assembly;
- the unit also comprising drive means for moving said dispenser head along an endless path about said assembly.
