This invention provides a woven tubular gasket having a continuous integral attachment means which is contained within the woven tubular members and which has protrusions which extend through or are extendable through the walls of the woven tubular member or members and are adapted to engage openings in an appropriate surface or substrate on which the gasket is to be attached. The method of this invention provides for continuously forming the combination of the attachment means and the woven tubular member. The attachment means is fed continuously into the interior of the woven tubular member as it is formed to thereby incorporate the attachment means into the interior of the woven tubular member.

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.
