Abstract
A pinch welt for trimming a flange formed on a vehicle body panel is disclosed. The welt includes a rigid insert made of a thermoplastic or synthetic rubber material that is compatible with the material of an outer decorative layer of the welt so as to allow the pinch welt to be readily recyclable as a single unit after use. The material of the insert has a resilience that allows the welt to be readily secured to the flange in a resilient manner. The insert is shaped by cooperating continuous forming rolls in an extrusion process that provides oppositely extending tines in which a thin webbing is formed between the tines.
