Abstract
A method of forming an intermittent stabilized length of a coextruded trim strip product. The method includes coextruding two strips of a thermoplastic material around intermittent sections of a stabilizing insert by a split extrusion die and forming rolls. A cutter cuts the trim strip product between the intermittent stabilizing sections so as to define trim strip products having ends without stabilizing inserts.
