ABSTRACT:
A wire carrier for use in the manufacture of weather seals is disclosed comprising a wire folded into a zig-zag configuration and having a plurality of generally parallel limbs for carrying a plurality of polymeric warp threads secured to the wire and at least one ribbon, having stiffening elements along its longitudinal axis, secured to the wire carrier such that the ribbon(s) runs substantially perpendicularly to the limbs of the wire. The ribbon may be secured to the wire by adhesive, by weaving, or by at least one row of warp thread. The resulting wire carrier is prevented from elongating during extrusion and thus a resulting product does not experience shrinkage. Methods for manufacturing the carrier are also disclosed.
