There is disclosed a method for applying sealant material between spaced-apart substrates in an insulated glass assembly. The method is sequential and employs extrusion nozzles and smoothing plates. The smoothing plates move in concert with the extrusion nozzles to ensure uniform distribution of the sealant material from the spacer, spacing the substrates, to the perimeter of the substrates. The smoothing plates ensure a uniform and planar surface at the perimeter. The method of operation is automated and accordingly, the sealant can be applied in an expedited manner with a high degree of precision and uniformity.

A method of applying sealant material between spaced substrates of an assembly having a spacer spaced inwardly from the perimeter of said substrates, said assembly having a pair of opposed lateral edges and a pair of transverse edges, comprising the steps of: providing applying means for applying sealant material between said substrates and smoothing means associated with said applying means for smoothing sealant material as it is applied; advancing said applying and smoothing means relative to the edges of the assembly simultaneously applying and immediately smoothing sealant material to the edges of the assembly; molding a substantially square corner of sealant material at each corner between each of the edges comprising the further steps of: slidably advancing said applying means from an edge having spacer material applied to it to an adjacent edge at said corner; slidably advancing said associated smoothing means to an adjacent position on the edge having spacer material applied to it thus closing the space between the substrates in the corner area; injecting spacer material into the corner area confined by said applying and smoothing means and molding a substantially square of spacer material; slidably advancing the associated smoothing means in alignment with the applying means on the adjacent edge; whereby the formation of strings of excess material is prevented.
