Abstract
An apparatus is disclosed for applying a plastic filament on the periphery of a face of a glass sheet which is adapted for use in the production of a multiple window pane unit. The apparatus includes an extrusion device for extruding on the glass sheet a plastic material having a viscosity greater than 115.degree. Mooney at the end of an 8 minute test at 40.degree. C. as measured by a Mooney consistometer, and support means defining a surface for supporting a glass sheet. The extrusion device includes a body portion and head member and an extrusion nozzle carried by the head member for extruding the plastic material. The nozzle extends from the head at right angles to the longitudinal axis of the device and the head is rotatable relative to the body portion about the longitudinal axis of the device to permit orientation of the nozzle at an angle of about between 15.degree. and 45.degree. with respect to the plane of the face of the glass sheet which is supported by the supporting means. The apparatus also includes means connected operatively to the body portion for vertically adjusting the extrusion device in conjunction with changing the angular orientation of the nozzle.
