also shown how by means of shadowing facility baffle 3 the deformation zone can be limited to obtain a deformation zone 5 with a height which is as low as possible thus both the distance and also the design of the heating facility 2 may serve for the adjustment of the height of deformation zone 5 fig5 shows the dependency of the widths of a glass product on the height of the deformation zone in a redrawing process it can be seen that a deformation zone with a lower height results in a reduction of the decrease of the width of the blank fig6 shows the distribution of thickness d of a flat glass product across width b of the product of example 3 here can be seen that the sheet edges at the rims of the glass product are relatively small the part with a homogenous low thickness can be used for the application of the glass product but the sheet edges have to be removed the use of the method according to the present invention results in a particularly high rate of yield fig7 shows in an exemplary manner average width b gross width of the drawn glass component and the drawing force which is required for drawing each in dependency on the viscosity of the glass of the blank in the deformation zone in the case of a blank having a thickness of 4 mm and a width of 400 mm which is fed into a muffle with a height of 40 mm with a speed of 5 mm min the glass is drawn with 200 mm min it can be clearly seen that the required drawing force increasingly increases with increasing viscosity furthermore.
