Abstract

So that no streaks or flaws are formed in the forming of watchglasses and the glass moulding obtains a uniform thickness, the glass blank (2) is placed by means of a heated displacing device onto a projecting edge (64) of a base die (61). The edge part of the glass blank is heated by means of two burners (84, 85) which are arranged with point symmetry with respect to the centre of the base die. Between the burners and the base die, flame screens (91, 92) are present which are moved between the burners and the base die in each case during placement of the glass blank onto the base die and during its removal therefrom, both of which operations are carried out by the heated displacing device and at periodic intervals during the heating of the edge region of the glass blank. The base die is arranged rotatably. <IMAGE>
