A method of mfg. floating glasses with the metal pool was described. A ribbon member in the metal pool zone which has the last discharge velocity, was received by upper return flow of cooled molten metal in adjacent zone deeper than depth of metal pools. From the pool, the upper molten flow was drawn to fill the molten metal flower by acceleration. The ribbon member was flowed along the molten metal pool and the force was added to the last member to accelerate the last discharge velocity and from the outlet of the metal pool the accompaniment of molten metal was increased gradually by cooled molten metals upper return flow.
