Abstract
A method of and a device are provided for the high-precision manufacture of glass lenses where a roughly metered volume of softened glass is transferred in a product holder from a furnace to a position between two moulds, the moulds being subsequently moved towards one another and the excess glass being pressed from between the moulds. The moulds and the product holder are moved at such a mutual speed that both moulds simultaneously contact the article, and the movement of the moulds is terminated when they reach a given position with respect to one another.
