ABSTRACT:
Nozzle apparatus for hermetically sealing the edges of multi-pane window units capable of performing such sealing even though the edges of the panes are misaligned. A thermoplastic sealing compound is introduced into the spacing at the edges of substantially aligned panes, and spring biased sealant containment plates disposed on opposite sides of the nozzle, each engaging a pane edge, confines the sealing material, and a blade associated with each containment plate trims the material with respect to each pane resulting in a clean joint from which excess sealing material has been trimmed, and the position of the trimming blades is automatically oriented to the pane edges.
