ABSTRACT:
A method of, and apparatus for, repairing mechanical and/or chemical damage to the surface of glass bottles destined for re-use. A bottle to be repaired is brought to a temperature in the region of the transformation point of the glass of the bottle, its surface is thermally treated with laser beams, and during the treatment the bottle surface is linearly scanned with the laser beams while rotating the bottle about its longitudinal axis to repair the surface. The apparatus comprises a laser source and optical means for directing the laser beam generated by the laser source onto the surface of a bottle being treated.
