ABSTRACT OF THE DISCLOSURE A method and apparatus for simultaneously applying sealing material to two opposite parallel edges of a multiple- pane window includes moving the window parallel to the opposite edges thereof between a pair of opposed extrusion nozzles, maintaining a substantially fixed separation of the nozzles during the travel of the window therebetween, and actuating the nozzles simultaneously to deposit sealing material from end to end of the opposite edges. In the apparatus, centering means are provided upstream of the nozzles and carrier means fixedly engages a window between the edges thereof. The centering means includes a pair of frames mounted for movement toward and away from each other in parallel relationship, and advantageously the nozzles are mounted at the downstream ends of the frame. The nozzles include means for resiliently biasing them toward the window edges and means for retracting them. The centering means may include a set of rollers for engaging each of the edges, and the sets of rollers may be mounted on respective rods which are turned to bring the rollers into engagement with the window edges. Switches and window edge detectors are used for controlling the centering means and for actuating the nozzles. -1-
