  • the adhesion between the material of the TPS strand and the glass surface can be significantly improved and the sealing properties, in particular with regard to undesired gas exchange and undesired penetration of water vapor, can be greatly improved.
  • the inventive combination of a primer station and a TPS station with a turning station and a pressing station with two parallel horizontal conveyors means that primer can be applied directly to the glass plate both on the first glass plate and on the second glass plate before the TPS strand is applied.
  • the primer strip can therefore be applied directly to the surface of the glass panel. This is a significant advantage as it makes the primer more effective.
  • contact of the applied primer with support means for supporting the standing glass panel is prevented, since the primer always hits the surface of the facing away from the support means Glass board is applied.
  • the TPS strand is then applied to the primer strip.
  • the width of the primer strip can correspond to the width of the TPS strand or be slightly wider.
  • the surfaces of the glass panels later lying inside the insulating glass pane do not come into contact with support means for supporting the standing glass panels. This is particularly important when these surfaces have sensitive coatings.
  • the spacer is formed by stacking two TPS strands, the height of which together gives the height of the spacer, then insulating glass panes can be produced particularly well, the glass panels of which have a relatively large distance from one another.
  • TPS strand When applying a pasty and subsequently solidifying TPS strand to a standing glass panel along its edge, it can happen that the still soft TPS strand sinks and / or inclines due to the force of gravity acting on it, if its height - measured perpendicular to the glass panel - is relatively large.
  • the height of the spacers formed by a TPS strand was therefore limited when placing orders on standing glass panels.
  • the total height required for the spacer can be divided between two TPS strands. In this way, undesired lowering or tilting of the respective TPS strand on the standing glass panel can be avoided.
  • This embodiment of the invention enables insulating glass panes and TPS spacers to be of very good quality, even if the distance between the two glass panels is more than 15 mm, in particular 16 mm to 32 mm.
  • this embodiment of the invention is very well suited for insulating glass panes in which a lattice frame is arranged between the two glass panels.
  • the lattice frame can be held by both TPS strands of the spacer in such a way that it is spaced apart from both glass panels and therefore does not directly touch either of the glass panels. This is particularly advantageous if a coating is present on the inside of the glass panel.
  • Insulating glass panes with TPS spacers and inserted lattice frames are known from DE 295 14622 U1.
  • a TPS strand was first applied to one of the glass panels at the height required for the spacer.
  • a lattice frame was then inserted into the frame-shaped spacer, the lattice frame being fastened by means of additional end pieces which were glued to one of the glass panels.
  • the insertion of the rung frame into the frame-shaped TPS spacer is prone to errors, since the material of the TPS cord is still soft and deformable at this time.

  • retaining elements can be arranged with which the bar frame can be placed on a surface of the still soft material of the TPS strand that is parallel to the glass panel. Then the rung frame is pressed in a little. A slight indentation is sufficient here, since the parts of the holding elements that still protrude beyond the surface of the TPS strand become one with the other glass sheet when they are joined together Also slightly press in the parallel surface of the TPS strand on the glass panel.
  • the retaining elements of the lattice frame are then half embedded in one of the two TPS strands. If both TPS strands are of the same height, the lattice frame is located exactly in the middle between the glass panels.
  • the rung frame can be positioned very precisely without the risk of the still soft TPS strand being undesirably deformed or damaged. This can improve the quality of the insulating glass panes produced and reduce the reject rate.
