ABSTRACT:
Apparatus for forming insulated glass from a first and second sheet of glass, normally with a spacer seal disposed therebetween, comprising a frame assembly having a rigid frame assembly, a plurality of torsion bars pivotably mounted thereto, an aluminum lower platen resting on a plurality of pistons capable of raising and lowering the lower platen, an upper platen fixedly attached to the frame substantially parallel to the lower platen, heating elements for heating the lower platen and the space between the lower and upper platens, and a control panel for operating the apparatus. The lower platen has a series of spaced apertures through which pass a plurality of ball bearing assemblies, each assembly being attached to the frame assembly. The control panel has an emergency stop switch, timer circuitry and temperature indicator/limit circuitry. An adjustable stop assembly permits fine adjustment of the maximum distance between the lower and upper platens when the lower platen is raised. The aluminum platen is essentially without any warpage and provides improved heat transfer between the heating elements and the glass. In use, an operator inserts a set of glass sheets to be processed on the lower platen and slides the glass over the bearings until it is in the desired location. Pressing the start switch raises the lower platen and activates the timed cycle. The preheated heating elements cause the glass compressed between the platens to be heated curing the spacer seal and forming the insulated glass assembly.
