Abstract: The invention is a flexible corner piece for use in the construction of a spacer frame for insulated glass panels. The corner piece is provided with opposing end sections suitable for mating with spacer tubes. In addition, the flexible corner piece has a variably flexible center section having a smooth and contiguous outer face opposing a parallel serrated face, thereby allowing the corner piece to flex along a variable radius.

Abstract: An automated apparatus for applying sealant, for example to insulated glass, is disclosed. The apparatus comprises a computer control and a support structure on which is movably disposed a sealant applicator. The sealant applicator is selectively positionable along at least one axis via the computer control one or more sensors operate to provide the computer control with data regarding sealant application as the sealant is applied. The computer control is further operative to both determine the depth of sealant to be applied, and to effect positioning of the sealant applicator in response to data from the one or more sensors such that sealant applied does not exceed the determined depth.

Abstract: An apparatus is disclosed for automatically cutting stock material for a grid. The apparatus comprise at least one saw assembly positionable to selectively cut the stock material into individual grid elements for the grid, a conveyor system operable to present the stock material for cutting by the at least one saw assembly, and a computer controller operable to generate instructions directing the operation of the conveyor system and the positioning of the at least one saw assembly so as to automatically cut the stock material into the grid elements.
