the invention relates to a method for producing an insulating glass pane comprising a plastic spacer , wherein two glass panels arranged parallel to each other have a target distance from each other , by □ forming a composite strand by the temporal and spatial overlapping extrusion of at least two plastic partial strands , wherein a first partial strand is made of an adhesive first sealing compound , in which a moisture - binding substance is embedded , and a second partial strand made of an adhesive and binding second sealing compound , a first glass panel along the edge of the glass panel , specifically such that the beginning and end of the composite strand abut and form a frame in that the first partial strand is extruded with a predetermined first target thickness , which is greater than the target distance , and the second partial strand is extruded with a predetermined second target thickness , which is greater than the target distance , on the glass panel , the partial strands are located next to each other in the composite strand and thus immediately adjoin each other , and the first partial strand is located within the frame formed by the second partial strand , □ joining the first glass panel to the second glass panel such that the composite strand is located between both glass panels , connects them to each other , and keeps them at a distance from each other and □ setting the target distance by pressing the joined glass panels .
