Zusammenfassung:The invention relates to a method of bending glass, in which method glass is heated in a bending furnace, and the glass is transferred onto a movable mould after its heating point or zone, whereby the glass bends upon the mould, and when the glass is being transferred onto the mould, the mould is moved in such a way that the horizontal velocity of at least the front edge of the mould is arranged to be substantially as high as the horizontal velocity of the glass. A method of bending glass, in which glass () is heated in a bending furnace (). Before the bending, the glass () is transferred from the heating point or zone onto a mould () located thereafter. While the glass () is being transferred onto the mould (), the mould () moves in such a way that the horizontal velocity of at least the front edge of the mould () is substantially as high as the horizontal velocity of the glass ().
