Abstract
In the production of a multiple pane window, a multiple layer plastic filamentary seal is deposited on the face of a transparent or translucent sheet adjacent the edges thereof over a major portion of the periphery. The seal is deposited by an extrusion nozzle from a starting point to an end point at a corner, by relatively moving and rotating the sheet past the nozzle. At least one layer of the multiple layer seal contains a larger proportion of desiccant material and another layer contains a smaller proportion or no desiccant material. At the starting and/or end points only the layer or layers containing the smaller proportion or no desiccant material is extruded. In a modification, at each corner only the layer or layers containing the smaller proportion or no desiccant material is extruded. A process for applying the seal, a multiple pane window resulting therefrom, and apparatus for applying the seal are described.
