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.

A method for applying sealing material between the panes of a multiple-pane window simultaneously at two opposing parallel edges thereof which comprises: (a) moving a multiple-pane window in a path of travel parallel to said two opposite edges thereof and between a pair of opposed extrusion nozzles

A method for applying sealing material between the panes of a multiple-pane window simultaneously at two opposing parallel edges thereof which comprises: (a) moving a multiple-pane window in a path of travel parallel to said two opposite edges thereof and between a pair of opposed extrusion nozzles adjacent said opposite edges, (b) centering said window using centering means having a pair of frames upstream of and attached to said nozzles and include engaging means mounted for pivotal movement for engaging said opposite parallel edges of said window, said frames mounted for movement toward and away from each other in parallel relationship by a lead screw having threads of opposite hand, (c) maintaining a substantially fixed lateral separation of said nozzles during the travel of said window therebetween, and (d) actuating said extrusion nozzles simultaneously to deposit sealing material from end to end of said opposite edges. Apparatus for applying material between the panes of a multiple-pane window simultaneously at two opposite parallel edges thereof which comprises: (a) a pair of opposed extrusion nozzles spaced apart laterally of the direction of travel of a multiple-pane window and maintained with a substantially fixed lateral separation during the travel of the window tHerebetween (b) centering means upstream of and attached to said nozzle for engaging opposite edges of said window and centering the window for passage between said nozzles said centering means includes: a pair of frames mounted for movement toward and away from each other in parallel relationship and include engaging means mounted for pivotal movement for engaging said opposite parallel edges of said window, said frames are coupled by a lead screw having threads of opposite hand longitudinally spaced thereon, said frames carrying cooperating threads of opposite hand respectively, and driving means for driving said lead screw in either direction, and (c) carrier means for fixedly engaging said window between said edges thereof and moving the window parallel to said edges past and between said centering means and said nozzles.
