    Abstract: PROBLEM TO BE SOLVED: To manufacture an article or part of a desired color having the appearance of coating material texture by coloring an elastomer denatured polyolefin material having a specified clouding level with a pigment having a specific effect. SOLUTION: At least one pigment having a specific effect is uniformly dispersed to a thermoplastic elastomer denatured polyolefin resin having low clouding degree, and thermally molded into a base material. The 'clouding degree' referred therein means the clouding degree of at least 50% or less for 60 mill black in measurement by ASTM D1003. The clouding degree is preferably 30% or less. As the pigment, an inorganic pigment or an organic pigment can be used. A specific pigment containing a flake pigment is used alone or in combination with a colored pigment in order to provide a specific effect as metallic appearance. This material can be molded into an automobile body member as a coating material or molding of body side surface or a bumper plate.

    Abstract: A method of forming an elongated trim strip product comprises extruding a first strip of thermoplastic material from a die having an outlet with an area at least substantially as great as the desired cross-sectional area of the strip product in planes perpendicular to the direction of extrusion. Immediately subsequent to the step of extruding and while the extruded strip is still in a plastic state, it is passed longitudinally between cooperating forming rolls to shape the cross section of the extruded strip to the desired shape and cross section of the strip product. While the extruded strip is passing between the cooperating forming rolls, a backing strip of foil or thin metal is directed between the rolls in alignment with the extruded strip to bond the backing strip to the extruded strip.

    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.

    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.

    Abstract: A method of forming an elongated trim strip product includes extruding a first strip of thermoplastic material from a die having an outlet with an area at least substantially as great as the desired cross-sectional area of the strip product in planes perpendicular to the direction of extrusion. Immediately subsequent to the step of extruding and while the extruded strip is still in a plastic state, it is passed longitudinally between cooperating forming rolls to shape the cross section of the extruded strip to the desired shape and cross section of the strip product. Further, while passing between the rolls a logo or lettering is formed on the strip. While the extruded strip is passing between the cooperating forming rolls, a backing strip of foil or thin metal is directed between the rolls in alignment with the extruded strip to bond the backing strip to the extruded strip. In a second embodiment, one or more cables of high strength flexible material, such as metal wire, are joined to or embedded in the extruded strip during the extrusion process to function as a pulling mechanism for moving the extruded strip through a cooling bath without stretching or deforming the extruded strip. After cooling, the cables can be severed from the strip if desired.
