Claim 8

A splicing strip, comprising: (a) a flexible, elongated sheet of fibers with openings having a largest diameter of approximately 0.05 to 0.50 inches; (b) a pair of tacky, mastic layers of material comprising by weight 10 to 50 parts of butyl rubber, 10 to 50 parts of polybutene and 10 to 80 parts of filler selected from the group consisting of calcium carbonate, mineral fillers, asbestos, carbon black, shredded rubber and mixtures thereof, one of said mastic layers being disposed on each side of said flexible sheet, said mastic layers being in adherent contact with each other across the openings in said flexible sheet; (c) a release sheet releasably attached to the outside face of one of said layers of mastic to permit removal of said release sheet and adhesive placement of the thus exposed outside face on the surface of components to be spliced; (d) a protective sheet of non-tacky, polymeric film in adhesive contact with the outside face of the other of said mastic layers; and (e) a stress distribution ribbon having a width substantially less than said splicing strip and being adhesively attached to and substantially on the longitudinal center line of the outside face of said mastic layer to which said release sheet is attached, said ribbon being impermeable to said mastic.

Claim 9

The splicing strip as in claim 6 wherein said release sheet is silicon treated paper.

Claim 10

The splicing strip as in claim 6 wherein said polymeric film is 1-50 mils thick.

Claim 11

The splicing strip as in claim 8 wherein said polymeric film is selected from the group consisting of polyester, polyvinyl fluoride, polyvinylidene chloride, polyvinyl chloride, chlorosulfonated polyethylene and stabilized rubbers.

Claim 12

The splicing strip as in claim 8 wherein the polymeric film is ethylene-propylene diene monomer.

Claim 13

The splicing strip as in claim 6 wherein said stress distribution ribbon is double knit polyester cloth.

Claim 14

The splicing strip as in claim 6 wherein the width of said stress distribution ribbon is approximately one-fourth that of the splicing strip.

Claim 15

The splicing strip as in claim 6 wherein a stress distribution ribbon is adhesively attached substantially along the longitudinal center line of the outside face of each mastic layer.

Claim 16

A splicing strip for joining together two or more components, comprising: (a) a flexible reinforcing sheet of synthetic organic fiber with openings having a largest diameter of approximately 0.05 to 0.50 inches; (b) a pair of tacky, mastic layers of material comprising 20 parts butyl rubber, 20 parts polybutene and 60 parts mineral filler, one of said mastic layers disposed on each side of said flexible sheet, said mastic layers being in adherent contact with each other across the openings in said flexible sheet; (c) a release sheet releasably attached to the outside face of one of said layers of mastic to permit removal of said release sheet and adhesive placement of the exposed outside face on the surface of components to be spliced; (d) a protective sheet of non-tacky polymeric film in adhesive contact with the outside face of the other of said mastic layers; and (e) a stress distribution ribbon having a width substantially less than said splicing strip and being adhesively attached to and substantially along the longitudinal center line of the outside face of the layer of mastic being placed in contact with the components to be spliced, said ribbon being of a material that precludes contact of the mastic with the component surface proximate said ribbon.

Claim 17

A splicing strip for joining together two or more components, comprising: (a) a flexible reinforcing sheet of synthetic organic fiber with openings having a largest diameter of approximately 0.05 to 0.50 inches; (b) a pair of tacky, mastic layers of material comprising 20 parts butyl rubber, 20 parts polybutene and 60 parts mineral filler, one of said mastic layers disposed on each side of said flexible sheet, said mastic layers being in adherent contact with each other across the openings in said flexible sheet; (c) a release sheet releasably attached to the outside face of one of said layers of mastic to permit removal of said release sheet and adhesive placement of the exposed outside face on the surface of components to be spliced; (d) a protective sheet of non-tacky polymeric film in adhesive contact with the outside face of the other of said mastic layers; and (e) a stress distribution ribbon having a width substantially less than said splicing strip and being adhesively attached to and substantially along the longitudinal center line of the outside face of the layer of mastic being placed in contact with the components to be spliced, said ribbon being of a material that precludes contact of the mastic with the component surface proximate said ribbon.
