METHOD FOR PRODUCTION OF GLASS COMPONENTS

摘要

A method for the production of glass components, an apparatus for carrying out the method, and a glass component that is obtainable through the method are provided. The method is a drawing method wherein a forming zone of a preform is heated to a temperature that allows drawing of the glass. The method includes a forming zone of the preform that is very small. Thereby the width of the preform is decreased to a smaller extent than its thickness. The glass components that can be obtained by this method have very smooth surfaces.

1. A method for redrawing of glass, comprising the steps of
providing a blank (1) of glass having an average thickness D and an average width B, heating a deformation zone (5) of said blank (1), and drawing of said blank (1) to an average thickness d and an average width b, characterized in thatthe deformation zone (5) is the part of said blank (1) in which said blank (1) has a thickness of between 0.95 *D and 1.05*d and wherein the deformation zone (5) has a height of at most 15*D.
