Abstract
A channel-shaped trim having a longitudinally extending opening for embracing and clamping an edge flange of a support member and a method for producing such a trim. The trim is comprised of a core member having a large number of disconnected channel-shaped core pieces and a covering member enclosing the core member and charged between the adjacent core pieces and in slots which are formed in the core pieces. The method for producing such a trim as described above comprises the steps of slotting a band-shaped sheet metal to form a core member comprised of a large number of core pieces composed of at least two strip-shaped elements spaced from each other and connecting portions connecting two strip-shaped elements, and weakened connecting portions connecting two adjacent core pieces, covering the core member with the covering material, breaking the weakened connecting portions, and bending the covered and broken core member to produce a channel-shaped trim.
