Abstract
A method of forming an elongated trim strip product by 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. 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.
