Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A method of forming a spiral wound gasket assembly having a gasket ring and an ouer metal gauge ring with flat guide surfaces between an inner groove and an outer peripheral edge, wherein the improvement comprising the steps of: forming a spiral gasket ring with the exterior diameter of the ring allowing positioning of the ring in the gauge ring groove; positioning the gasket ring within the gauge ring; and deforming a portion of the gauge ring to reduce the size of the gauge ring groove to tighten and retain the gasket ring within the groove.
Claim 2
Independent Claim
96 words
A method of forming a spiral wound gasket assembly having a gasket ring and an ouer metal gauge ring with flat guide surfaces between an inner groove and an outer peripheral edge, wherein the improvement comprising the steps of: forming a spiral gasket ring with the exterior diameter of the ring allowing positioning of the ring in the gauge ring groove; positioning the gasket ring within the gauge ring; and deforming a portion of the gauge ring to reduce the size of the gauge ring groove to tighten and retain the gasket ring within the groove.
Claim 3
Dependent Claim
46 words
The method as set forth in claim 1, wherein: the step of deforming includes locating the gasket assembly in a deforming apparatus and forming circumferential deformations in each of the flat surfaces of the gauge ring adjacent the groove to reduce the size of the groove.
Claim 4
Dependent Claim
28 words
The method as set forth in claim 1, wherein: the step of deforming includes deforming a side portion adjacent the groove to reduce the size of the groove.
Claim 5
Dependent Claim
47 words
The method as set forth in claim 1, wherein: the step of deforming includes reducing the size of the gauge ring an amount sufficient to tightly retain the gasket ring in the groove providing a non-sliding fit and limiting radial deformation of the gasket ring under load.
Claim 6
Dependent Claim
46 words
The method as set forth in claim 1, wherein: the step of deforming includes reducing the size of the gauge ring groove an amount sufficient to retain the gasket ring in the groove while still allowing a sliding fit between the gasket ring and gauge ring.
Claim 7
Dependent Claim
32 words
The method as set forth in claim 1, wherein: the step of deforming includes forming circumferential indentions adjacent the groove in each of the flat surfaces to provide said tightening and retaining.
