| (54) | The method of modifying the flat glass surface and the apparatus for carrying out this method |
| (57) The method of modifying the flat glass surface is based on that the surface of a
glass is worked by abrasive grains of synthetic diamond which are situated in the
mass of plastic threads that are a part of a rotating brush. The glass is first tarnished
using brushes with rougher abrasive grains of synthetic diamond and then tarnishing
is finished using brushes with smaller abrasive grains. With the brushes, it is also
possible to modify already sandblasted glass surface. The apparatus for modifying
glass surface is made up of at least one rotating brush (9, 10) that is bedded in
static or moveable disposition above the glass plate (5) which is to be modified,
while the brush (9,10) has abrasive plastic threads (3) embedded with abrasive grains
of synthetic diamond.
