A carrier for a channel-shaped trimming or sealing strip is manufactured by leading a main wire between meshing teeth so as to give the wire a zig-zag configuration. The emerging wire is pushed between guide walls. Simultaneously, looped edge wires are fed in, along the walls, and mesh with the ends of the loops of the main wire. The meshed wires are fed into the mouth of a cross-head extruder. This extrudes plastics or rubber material around the meshed wires so as to hold them in meshing engagement. The resultant generally flat strip can then be bent into channel-shape. |
