Abstract: A method for making a V-ribbed belt is made by inserting a first partial blank in the form of a base tube into a cylindrical vulcanization mold having a negative of a V-ribbed profile. The first partial blank is molded into a surrounding negative and thus provided with the V-ribbed profile without vulcanization. A second partial blank made as a top ply tube with a tension strand is inserted into the virtually completely molded-in base tube and is expanded under heat and pressure so that the top ply tube and the base tube are bonded to one another. Thereafter, the latter is molded into the surrounding negative of the vulcanization mold, and the top ply tube and the base tube are vulcanized to form a V-ribbed blank, whereafter the V-ribbed blank is removed from the vulcanization mold and is fed to the cutting device.
