Abstract

Apparatus for producing all-glass multiply sheet glazing units including a preheating section, a sealing section and annealing and cooling sections. The preheating section and the annealing and cooling sections are located in spaced, substantially parallel relation to one another with the exit end of the preheating section and the entry end of the annealing section being open communication with opposite end areas of the sealing section. One conveyor system provides a horizontal, substantially continuous rectangular path of movement for carrying a plurality of support means for glass sheets through the preheating section to raise the temperature of the glass sheets above the point of strain. Each support means is then carried to an area in which it is positioned to receive a completed glazing unit to convey the same through the annealing and cooling sections to an unloading area where the glazing unit is removed from the support means. Another pair of sheets to be formed into a glazing unit are then placed on the support means and moved into the entry end of the preheating section. A second conveyor system provides a second horizontal, substantially continuous rectangular path of movement in a plane in parallel with and above the first conveyor system for moving a plurality of carrier means for the glass sheets through the sealing section, to form them into a completed glazing unit, with means for then transferring each empty carrier means for movement along a return section arranged in spaced parallel relation to the sealing section. The return section includes transfer means to deliver the carrier means to the entry end of the sealing section. As herein provided, the sequences of movement of the sheet support means and of the carrier means are automatically controlled and interlocked to also effect vertical lifting of a pair of sheets from a support means to a carrier means positioned thereabove and eventual vertical lowering of a finished glazing unit from the carrier means to a supporting means therebeneath.
