  • Method of applying an extruded profile to a window glazing
    Patent number: 6607622
    Abstract: A method for adhering/bonding a frame profile (e.g., weather strip, water seal, spacer, etc.) to a substrate (e.g., glass or plastic substrate) in the context of a vehicle window unit. A frame profile is formed via extrusion so as to include both a polymer profile portion and a selectively activatable interface or adhesive portion. Following extrusion, the frame profile may be stored, cut, trimmed, cure, etc. At some point following extrusion, the interface/adhesive is in a non-activated state, or at least in a state where it is not activated to an extent sufficient to bond/adhere the frame to the substrate. To adhere/bond the frame profile to the substrate, the interface/adhesive portion of the frame profile is activated (e.g., heat activated). Following and/or during heat activation, the frame profile is pressed against the substrate, or vice versa, so that the activated adhesive bonds the polymer profile to the substrate.

  • Method of applying extruded profile to corners of a window glazing
    Patent number: 6513854
    Abstract: A method for adhering/bonding a frame profile (e.g., weather strip, water seal, spacer, etc.) to a substrate (e.g., glass or plastic substrate) in the context of a vehicle window unit. An extruded frame profile is cut, notched, and/or heated in order to create a corner portion thereof that will more easily conform to a corner area of the substrate. In certain embodiments, a V-shaped notch may be cut in the profile, while in other embodiments the profile may be mitered. In still further embodiments, the profile may be heated in order to enable a corner area thereof to more easily bend/stretch at a corner area of the substrate to which it is bonded/attached. The profile may be bonded/attached to the substrate via double sided tape, via selectively heat-activatable adhesive, or any other suitable adhesive.
