1. along the bending glass sheet and make the bending machine of sheet glass tempering afterwards on the shaping platform that constitutes by shaped bar of the track with curved profile;

  • Comprise that some are used to make the device that sheet glass (1) of guiding order is advanced under softening temperature in advance;

    So that sheet glass is had along the curved shape of the expectation of said track with curved profile, and crooked tempering zone, this bending tempering zone comprises the extruding sheet glass so that said sheet glass obtains the upper roller of the profile corresponding with the shaping platform;

    It is characterized in that;

    This bending machine also comprise at least one continuously the pipe of blowing air (3,3a), this blowing pipe is arranged on a position of sheet glass line of travel;

    After sheet glass has begun to be shaped and before crooked termination phase, said pipe (3;

    3a) be arranged between two adjacent shaped bars of said shaping platform, be used for implementing said sheet glass (1) is only carried out asymmetric blowing air on a side, said pipe (3 at its mobile axis relatively;

    3a) be conditioned the final concavity that the bending that is used to make said air blowing not have relatively to dry to have given influences bending glass sheet, said crooked tempering zone is positioned at said pipe (3;

    Downstream 3a).
