摘要： The invention relates to a method for producing blank-pressed glass bodies for optical components, according to preforming technology, whereby a liquid glass gob is supplied to a levitation preform mould in which said glass gob is preformed to form a parison, without touching the mould surface. After a defined period of time, said parison is transferred to a separate compression mould and is pressed therein by means of a press tool in order to form the end shape. The parison (1) is transferred to the compression mould (2) in such a way that it falls freely from the preform mould into the compression mould (2). According to the invention, the preform mould (1) is displaced above the compression mould (2) for the transfer of the glass gob, is maintained in said transfer position, and is downwardly pivoted away from the glass gob.
