Abstract
Abstract A method of applying an integral sealing member to a shaped surface which in its operative environment is to be disposed in sealed relationship with another surface and the resulting products. The method comprises dispensing a composition adapted to be cured to form said sealing member onto a work surface adapted to be adjusted to a desired configuration, partially curing said composition such that it does not flow, adjusting the disposition of said work surface bearing the partially cured composition such that said shaped surface to which the sealing member is to be integrally bonded may be disposed along said work surface, positioning said shaped surface along said work surface such that said shaped surface is at least in contact with said partially cured composition, completing the curing of said composition and removing said shaped surface with said sealing member integrally bonded thereto from said work surface. The invention has particular significance with respect to the application of sealing members to various automotive parts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
A method for applying an integral sealing member to a non-planar surface member comprising: A. dispensing an elastomer composition adapted to be cured to form said sealing member into a groove in a mold member which is disposed essentially in one plane; said mold member being adapted to have at least a portion thereof adjusted from a planar to various non-planar positions; B. partially curing said composition such that it does not flow; C. adjusting the disposition of at least a portion of said mold member having said groove therein and containing said partially cured composition such that said groove is no longer disposed in one plane and such that said nonplanar surface member may be embedded within the composition within said groove along the entire portion thereof to which said sealing member is to be applied; D. positioning said non-planar surface member within said groove containing said partially cured composition such that at least a portion thereof is embedded therein along the entire portion thereof to which said sealing member is to be applied; E. completing the curing of said composition; and F. removing said non-planar surface with said sealing member integrally bonded thereto from said groove.
Claim 2
Independent Claim
198 words
A method for applying an integral sealing member to a non-planar surface member comprising: A. dispensing an elastomer composition adapted to be cured to form said sealing member into a groove in a mold member which is disposed essentially in one plane; said mold member being adapted to have at least a portion thereof adjusted from a planar to various non-planar positions; B. partially curing said composition such that it does not flow; C. adjusting the disposition of at least a portion of said mold member having said groove therein and containing said partially cured composition such that said groove is no longer disposed in one plane and such that said nonplanar surface member may be embedded within the composition within said groove along the entire portion thereof to which said sealing member is to be applied; D. positioning said non-planar surface member within said groove containing said partially cured composition such that at least a portion thereof is embedded therein along the entire portion thereof to which said sealing member is to be applied; E. completing the curing of said composition; and F. removing said non-planar surface with said sealing member integrally bonded thereto from said groove.
