Abstract

Abstract A magneto-responsive composite molding comprising an elongate casing adapted for operative association with a closure such as a door edge. The casing includes a pair of opposing faces one of which is adapted to contact and be concealed by the a closure or door edge and the other of which is adapted to be exposed relative to the closure or door edge. The composite molding furthermore includes at least one metallic strip which is encapsulated within the casing between the pair of opposing faces of the latter. The metallic strip is constituted of magnetically responsive material for responding to a magnetic force or magnetic forces of a magnetic field provided by a magnetic element mounted in the door frame across which the door edge may be swung.

Independent Claim 20 words
A composite molding as claimed in claim 1, wherein said second metallic strip is also constituted of magnetically responsive material.
Claim 2
Dependent Claim 19 words
A composite molding as claimed in claim 1, wherein each of said metallic strips is co-extensive with one another.
Claim 3
Dependent Claim 38 words
A composite molding as claimed in claim 3, wherein said metallic strips have a combined width transversely of said opposing faces of said casing substantially greater than that portion of the thermoplastic wherein said exposed other face extends.
