  • Patent number: 5382401
    Abstract: A stabilizer guide for guiding a stabilizer, having a material characteristic of fraying, through an extrusion die without fraying and melting the stabilizer during the extrusion of a thermoplastic body molding of a motor vehicle. The stabilizer guide is made up of two halves that join to form a parting line and a slot by which to guide the stabilizer through the extrusion die. The slot extends along the entire length of the stabilizer guide and is located in a different plane than the parting line of the stabilizer guide. By having the slot in a different plane than the parting line, the stabilizer is prohibited from wandering into the parting line. This prevents the stabilizer from fraying and shredding and causing the slot to be obstructed by pieces of the stabilizer. Obstruction of the slot hampers the stabilizer from being guided through the stabilizer guide.
