Abstract
A method of fabricating a rectilinear window frame comprising cutting a length of extruded frame profile having a body portion and an integral nailing fin into four lengths from opposite sides of the profile at forty-five degrees (45°) with the cuts meeting at a point intermediate the width of the nailing fin, then assembling the four sections into the rectangular frame. The invention is also directed to frames produced by such method.References Cited

- 1. A method of fabricating a window frame of extrudable material, said frame having a body portion for insertion into a rectangular window opening and an integral nailing fin for circumscribing the window opening comprising extruding a length of profile having a cross sectional configuration corresponding to the desired window frame body portion and an integral nailing fin, the length of said profile being equal to the perimeter of the opening into which the body portion of said frame is to be inserted plus eight times a selected fraction of the width of the nailing fin, cutting said profile from opposite sides thereof at angles inclined at forty-five degrees (45°) to the length of said profile with the cuts meeting at a point in the nailing fin which is at said selected fraction of the width of the nailing fin to form four frame sections whose nailing fin ends are right angled triangles having their apexes at said point in said nailing fin, welding said four frame sections together to form the window frame and a circumscribing integral nailing fin.
