Claim 2

A gasket for sealing a space between two surfaces, one of said surfaces having a series of spaced openings therethrough, said series being arranged in the pattern desired for the gasket, said gasket comprising: (a) at least one woven tubular member having a hollow interior and comprising woven strands; and (b) an integral continuous attachment means positioned inside the tubular member, being adapted to hold the tubular member in said pattern when assembled on said one of said surfaces, said attachment means comprising a flexible metal wire extending generally axially inside the hollow interior of said woven tubular member, said flexible metal wire being of diameter representing only a minor fractional percentage of the hollow interior diameter of the surrounding woven tubular member to provide freedom for limited relative lateral flexing of the flexible metal wire within the surrounding woven tubular member, said flexible metal wire having a lateral portion to provide stability for the attachment means inside the tubular member while permitting said limited flexing by being engageable with the interior of the woven tubular member to thereby limit the extent of said flexing, said flexible metal wire further having protrusions protruding from bases and which protrusions have shoulder means for engaging said openings in said one surface and which protrusions extend outwardly through the weave of the tubular member and thus form apertures in the weave without breaking or cutting a significant number of the woven strands and substantially without permanently interfering with the strands of the tubular member, with the result that said apertures in the weave around the bases of the protrusions are smaller than the shoulder means of the protrusions and which protrusions are adapted to engage said openings in said one surface to thereby connect the attachment means to said one surface.

Claim 3

A gasket according to claim 1 wherein the tubular member is knitted.

Claim 4

A gasket according to claim 1 wherein the tubular member is braided.

Claim 5

A gasket according to claim 1 wherein the gasket further comprises at least a second woven tubular member positioned inside the first tubular member and wherein the attachment means is positioned inside the second tubular member and the protrusions extend outwardly through the weaves of both the first and second tubular members and are adapted to engage said openings in said one surface.

Claim 6

A gasket according to claim 1 wherein the gasket further comprises at least a second woven tubular member positioned inside the first tubular member and wherein the attachment means is positioned between the first tubular member and the second tubular member.

Claim 7

A gasket according to claim 1 wherein the gasket further comprises separate retaining means positioned on the outside of the tubular member and adapted to prevent the protrusions from being pulled through the weave of the tubular member toward the inside of the tubular member.

Claim 8

A heat resistant gasketing assembly for sealing space between an oven and an oven door, one of said oven and oven door having a series of spaced openings therethrough, said series being arranged in the pattern desired for the gasket of the assembly, said gasket including woven strands comprising: (a) at least one woven wire tubular member having a hollow interior; and (b) at least one woven fiberglass tubular member surrounding same; and an integral continuous attachment means for removably positioning with relation to and attaching said tubular members to said one of said oven and oven door comprising a flexible metal wire extending generally axially inside the hollow interior of said woven wire tubular member and against the interior of said woven wire tubular member, said flexible metal wire being of diameter representing only a minor fractional percentage of the hollow interior diameter of the surrounding woven wire tubular member to provide freedom for limited relative lateral flexing of the flexible metal wire within the surrounding woven wire tubular member, said flexible metal wire having a lateral portion extending laterally back and forth along the length of the metal wire to provide stability for the attachment means inside the tubular members while permitting said limited flexing by being engageable with the interior of the woven wire tubular member to thereby limit the extent of said flexing, said flexible metal wire further having preformed integral protrusions extending substantially perpendicularly to said lateral portion and which have shoulder means for engaging said openings in said one of said oven and oven door to thereby connect the attachment means and the tubular members to said one of said oven and oven door in the pattern desired for the gasket and which extend outwardly through the weave of the tubular members without breaking or cutting a substantial number of the woven strands and substantially without permanently interfering with the strands of the tubular members.

Claim 9

A heat resistant gasketing assembly for sealing space between an oven and an oven door, one of said oven and oven door having a series of spaced openings therethrough, said series being arranged in the pattern desired for the gasket of the assembly, said gasket including woven strands comprising: (a) at least one woven wire tubular member having a hollow interior; and (b) at least one woven fiberglass tubular member surrounding same; and an integral continuous attachment means for removably positioning with relation to and attaching said tubular members to said one of said oven and oven door comprising a flexible metal wire extending generally axially inside the hollow interior of said woven wire tubular member and against the interior of said woven wire tubular member, said flexible metal wire being of diameter representing only a minor fractional percentage of the hollow interior diameter of the surrounding woven wire tubular member to provide freedom for limited relative lateral flexing of the flexible metal wire within the surrounding woven wire tubular member, said flexible metal wire having a lateral portion extending laterally back and forth along the length of the metal wire to provide stability for the attachment means inside the tubular members while permitting said limited flexing by being engageable with the interior of the woven wire tubular member to thereby limit the extent of said flexing, said flexible metal wire further having preformed integral protrusions extending substantially perpendicularly to said lateral portion and which have shoulder means for engaging said openings in said one of said oven and oven door to thereby connect the attachment means and the tubular members to said one of said oven and oven door in the pattern desired for the gasket and which extend outwardly through the weave of the tubular members without breaking or cutting a substantial number of the woven strands and substantially without permanently interfering with the strands of the tubular members.

Claim 10

A gasket for sealing a space between two surfaces, one of said surfaces having a series of spaced openings therethrough, said series being arranged in the pattern desired for the gasket, said gasket comprising: (a) at least one woven tubular member having a hollow interior and comprising woven strands; and (b) an integral continuous attachment means positioned inside the tubular member, being adapted to hold the tubular member in said pattern when assembled on said one of said surfaces, said attachment means comprising a continuous elongated flexible member extending generally axially inside the hollow interior of said woven tubular member, said flexible member being of cross-sectional area representing only a minor fractional percentage of the cross-sectional area of the hollow interior of the surrounding woven tubular member to provide freedom for limited relative lateral flexing of the flexible member within the surrounding woven tubular member, said flexible member having a lateral portion to provide stability for the attachment means inside the tubular member while permitting said limited flexing by being engageable with the interior of the woven tubular member to thereby limit the extent of said flexing, said flexible member further having protrusions protruding from bases and which protrusions have shoulder means for engaging said openings in said one surface and which extend outwardly through the weave of the tubular member and thus form apertures in the weave without breaking or cutting a significant number of the woven strands and substantially without permanently interfering with the strands of the tubular member, with the result that said apertures in the weave around the bases of the protrusions are smaller than the shoulder means of the protrusions and which protrusions are adapted to engage said one surface to thereby connect the attachment means to said one surface.
