1. the manufacture method of a press molding usefulness preform wherein, makes fused glass block and separates from the effusive molten glass flow of pipeline, and on the glass block shaping dies, described fused glass block is configured as the press molding preform, it is characterized in that:

  • Receive the front end of described molten glass flow by the supporting mass that is arranged on described pipeline below, and described supporting mass reduced to isolate fused glass block from this molten glass flow, this fused glass block is moved on the glass block shaping dies,Further comprising the steps of, that is;

    from the front end that receives described molten glass flow by supporting mass to described fused glass block was moved in time between the glass block shaping dies, fused glass block with described supporting mass state of contact under to support, to get rid of the heat of fused glass block by thermal conduction, promote the viscosity of this melten glass to riseAfter above-mentioned steps, the operation that described melten glass is floated on supporting mass.
