Abstract: A gasket, particularly for use with an oven door, has features that allow it to be bent into a rectangular shape. The gasket has a base that is extruded with a tubular section that protrudes outwardly from it. A wire is simultaneously drawn through the base while the gasket is being extruded. The wire is sufficiently ductile to allow the gasket to be bent into a rectangular shape, and has sufficient strength to hold the gasket in that shape. Resilient metal clips are used to grip the base and extend into apertures provided in the oven for securing the gasket to the oven.

Abstract: A pneumatic gasket adapted to be used in an oven door construction in which the door is adapted to be sealed to an oven surface when the door is closed. The gasket is an elongate extensile elastomeric member with first and second sections. The second section is a hollow member which is sealed at its ends or at other desired locations, the space between each of these sealed points forming a hollow air chamber of substantial volume which will expand when exposed to the temperatures produced by an operating oven. The second section may be sealed to produce the air chambers by adhesives such as a room temperature vulcanizing adhesive or by mechanical means. The second section may be a coextensive flap hingedly secured along one edge of the first section. The gaskets have means connected to the first sections removably to secure them to the oven surface to hold them in place between the oven and the door, while allowing them easily to be removed to replace them or to clean the oven.
