摘要： An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided. A unique method of making such an edge coated gasket is also disclosed.

摘要： A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding. A process for coating the gasket edges which are around the aperture comprises placing the gasket sheets together so that a cavity is formed by the apertures, the sides of the cavity are the aperture edges to be coated. The coating material is put into the cavity and contacts the edges to be coated to form the coated edges.

摘要： A soft gasket material having two opposed facial surfaces and an edge that is substantially perpendicular to those surfaces has a coating on the edge. The coating has a thickness length B which is a distance extending directly from the edge at its center point to the coat's outer surface. The coating further covers the edge from side to side and extends past at least one corner of the edge in a protruding length A which is an amount that is effective to form a barrier against the passage of fluids onto the face of the gasket. In coatings where the protruding length A is not supported by the gasket face, the ratio of protruding length A: thickness length B must be at least about 0.8, protruding length A must be a minimum of at least about 4 mils, and thickness length B must be a minimum of at least about 3 mils. In coatings where the protruding length A is supported by the gasket face (a distance C), the ratio of protruding length A: thickness length B can be at least about 0.6, protruding length A can be a minimum of at least about 3 mils, and thickness length B can be a minimum of at least about 2 mils.
摘要翻译：具有两个相对的面部表面和基本上垂直于这些表面的边缘的软垫片材料在边缘上具有涂层。该涂层的厚度长度B是从中心点的边缘直接延伸到外套的外表面的距离。涂层进一步从一侧到另一侧覆盖边缘，并且以突出长度A延伸穿过边缘的至少一个角度，该突出长度A是有效形成抵抗流体到垫圈表面上的阻挡物的量。在其中突出长度A不被垫圈面支撑的涂层中，突出长度A：厚度长度B的比率必须至少为约0.8，凸出长度A必须至少为至少约4密耳，厚度长度B 必须至少约3密耳。在其中突出长度A由垫圈面（距离C）支撑的涂层中，突出长度A：厚度长度B的比率可以为至少约0.6，突出长度A可以为至少约3密耳的最小值，并且厚度长度B可以是至少约2密耳的最小值。
