Zusammenfassung:	A system, method and apparatus for making endless belts having a profile layer, a fully embedded, helically wound, cord layer, and a top layer. The apparatus has a rotatable mandrel (2) with a profile complementary to the belt profile (1), two or one engagement rolls adjacent the mandrel to maintain forced, wrapped engagement of the profile layer on a portion thereof; a cord applicator which may include a heated blade (5) that plows a groove in the profile layer into which the cord is laid and fused thereto. A laminator applies the top layer onto the reinforced carcass. A system of buffer rolls (14) handles the loose portion of the profile layer or carcass guiding it.
