Abstract
Abstract Apparatus for producing a trim strip assembly is disclosed. The trim strip includes a thermoplastic base member, a superimposed strip, and a plastic top coating. The superimposed strip may be of plastic, metal or foil. The apparatus includes extruders and a die having three passageways. A first passageway receives the extruded base member, a second passageway intersects the first passageway and receives the superimposed strip, and a third passageway intersects the second passageway a predetermined distance from the intersection of the first and second passageways.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
154 words
Apparatus for forming a trim strip assembly including a longitudinal base member, a superimposed strip and a plastic top coating, said apparatus comprising, in combination, a die defining a first passageway for receiving a thermoplastic extruded base material, said first passageway extending so that said extruded base material moves in a planar path and having an outlet orifice of a desired configuration, said die defining a second passageway for receiving the strip, said second passageway intersecting said first passageway, said die defining a third passageway which Intersects said second passageway at a point which is located a predetermined distance upstream from the intersection of said first and second passageways for contacting the strip and the plastic top coating entering from the third passageway before the base member is contacted by the strip, and said third passageway having an outlet orifice of another desired configuration oriented for laying a composite strip on said base material.
Claim 2
Dependent Claim
154 words
