Abstract: An elongated extruded strip with a wire core having a selectively positioned neutral bending axis is made by coextruding an elastomeric extrudate at an elevated temperature about a wire core having adjacent parallel transverse wire lengths joined by low temperature threads having a melting point lower than the said elevated temperature while simultaneously feeding at least one high temperature thread into the extruder in bonding relationship to the elastomeric extrudate and in selected position therewith.

Abstract: There is disclosed a sealing device (7) comprising an elongate sealing portion (8) secured substantially along its length to an adhesive means (10) having an outer adhesive surface (11) remote from the sealing portion. The device further comprises a plurality of protruding members (12) positioned at predetermined intervals along its length and having a protruding end (15) protruding from the outer adhesive surface (11) of the adhesive means (10). The protruding members (12) comprise a flat portion (13) of small thickness opposite the protruding end (15). Also disclosed is a sealable body in which the sealing device is used and methods for forming the sealing device.
