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 composed of a band-shaped metal network which covered and finally broken either partially or totally and thereby separated into a plurality of transversely extending strips, blocks, or into a substantially continuous strip extending along a meandering line through the trim.
The method for producing such a trim includes the steps of preparing a band-shaped network with transversely and longitudinally disposed connecting portions and spaces disposed therebetween, covering the network with an elastic or bondable covering material, such as rubber or a synthetic resin, transversly breaking the connecting portions partially or totally in the covered network and bending the covered and broken network in the transverse direction to produce a channel-shaped trim.
