Claim:
A method of making an open-ended, reinforced, layered belt comprising; training a plurality of parallel tensile cords on a portion of a smooth, rotating, cylindrical mandrel, said portion including a first cavity defined between said smooth mandrel and a molding band or a first gap defined between said smooth mandrel and a laminating roller; extruding a top layer material onto said cords and metering it into said first cavity or into said first gap; thereby forming a carcass comprising said cords embedded at one surface of a film of said top layer material; training said carcass on a portion of a profiled, rotating, cylindrical mandrel having a profile complementary to a desired belt profile, said portion including a second cavity defined between said profiled mandrel and said molding band or a second gap defined between said profiled mandrel and said laminating roller, and said one surface facing said profiled mandrel; extruding a profile layer material onto said profiled mandrel between said carcass and said profiled mandrel surface and metering it into said second cavity or into said second gap; thereby forming said belt comprising said cords embedded between said top layer material and said profile layer material.
