Abstract
When producing insulating glass including at least two panes of glass (1) and at least one spacer of thermoplastic material arranged between the panes of glass, to seal the beginning (4) and the end (5) of the strand (2) of thermoplastic material the thermoplastic material is compressed with the aid of jaws placed against the side faces of the strand. In the region of the joint thus formed between the beginning and the end of the strand forming the spacer, the width of the strand is reduced with the aid of a compression die with a convexly curved active face such that a depression is created. This depression has the effect that, after the assembly of an insulating glass blank, placing a second pane of glass onto the free edges of the strand produces an opening that allows a pressure equalization during the subsequent compression of the insulating glass blank.
