Abstract
Abstract Wire fabric containing a break is repaired by removing therefrom a section encompassing the break, locking in its stead in nonoverlapping relationship a patch coated with bonding material, and then bonding the patch to the fabric by effecting a bonding temperature about the periphery of the patch. A device is also described comprised of heating elements for the bonding operation and preferably magnetic locking means for maintaining the patch in non-overlapping place during the repair operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
The method of repairing Fourdrinier wire fabric containing a break in one or more of the weft or warp strands thereof to reestablish the uniform continuity of said fabric, consisting essentially of removing therefrom a section of fabric comprised of a plurality of the said warp and weft strands and wholly encompassing the break, locking in its stead in non-overlapping relationship a complementary patch of Fourdrinier tape wire such that no portion of the patch extends beyond the periphery of the void created by removing said section, said patch coated at least at its edges with a thin film of bonding material, and thence bonding the patch to the fabric while in such non-overlapping relationship.
Claim 2
Independent Claim
115 words
The method of repairing Fourdrinier wire fabric containing a break in one or more of the weft or warp strands thereof to reestablish the uniform continuity of said fabric, consisting essentially of removing therefrom a section of fabric comprised of a plurality of the said warp and weft strands and wholly encompassing the break, locking in its stead in non-overlapping relationship a complementary patch of Fourdrinier tape wire such that no portion of the patch extends beyond the periphery of the void created by removing said section, said patch coated at least at its edges with a thin film of bonding material, and thence bonding the patch to the fabric while in such non-overlapping relationship.
Claim 3
Dependent Claim
19 words
The method as defined by claim 1, wherein the patch is comprised of fabric identical to that undergoing repair.
Claim 4
Dependent Claim
16 words
The method as defined by claim 2, wherein the patch Is magnetically locked in non-overlapping place.
Claim 5
Dependent Claim
19 words
The method as defined by claim 3, wherein the patch is coated in its entirety with the bonding material.
Claim 6
Dependent Claim
31 words
The method as defined by claim 3, wherein the warp and weft strands of the patch are aligned with those of the fabric prior to locking the patch in non-overlapping place.
Claim 7
Dependent Claim
27 words
The method as defined by claim 3, wherein the bonding operation is effected by raising the temperature about the periphery of the patch to a bonding temperature.
Claim 8
Dependent Claim
16 words
The method as defined by claim 3, wherein the section removed and the patch are circular.
