There is disclosed a method and apparatus for applying sealant material to the void in the perimeter between spaced-apart substrates in an insulated glass assembly. An apparatus includes a traveling applicator head and a stationary head, both applicator heads including a nozzle member and independently movable wiper member which cooperate to apply a smooth and even layer of sealant material. An advantage of the cooperating nozzle and wiper members is the ability to mold corners and to apply sealant material without lifting the applicator from the glass assembly. The method is sequential and employs two cooperating applicator heads, conveyors and position sensors to permit fully or semi-automated operation. The smoothing plates move in concert with the extrusion nozzles to ensure uniform distribution of the sealant material from the spacer, and 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.
