  • Method of forming automotive trim strip from extruded thermoplastic materials
    Patent number: 5904884
    Abstract: A process for forming a specific length of extruded thermoplastics material trim strip for automobiles includes the step of extruding the strip directly onto an endless carrier belt moving at a speed matching the emergence speed of the extrudate. The extrudate, therefore, is less subject to stresses causing unpredictable length changes on cooling. It is therefore possible to predetermine the cooled, matured, final lengths of strip and to provide moulded end portions on-line.
