Abstract
A method and apparatus for applying a plastic strand (35), as a spacer with a predefined intended thickness (D), onto a glass panel (33) in order to constitute insulating glass panes, by means of a nozzle (17) which is moved along the edge of the glass panel (33) around the latter and thereby deposits the strand (35) emerging from the nozzle (17) onto the glass panel (33) so that the beginning and end of the strand (35) abut one another. The thickness of the strand (35) upon emergence from the nozzle (17) is increased, at the beginning of a segment with a defined length (L), from zero to the intended thickness (D); and in complementary fashion thereto, at the end of the strand (35) is decreased over the same length from the intended thickness (D) to zero.
