  • Patent number: 10385609
    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.

  • Patent number: 9540864
    Abstract: A method and apparatus for the, preferably automated, changing of spacers in a plant having at least one applicator head for applying spacers to panel-shaped workpieces, in particular glass panes. Spacers from at least two sources are fed to the applicator head in an offset manner with respect to one another. A first spacer from a first source is separated. The resulting end of the first spacer and a start of the second spacer, which comes from a second source, are moved into a mutually assigned position by a changing device. Then, the end of the first spacer is connected to the start of the second spacer. A resulting connection of the first spacer with the second spacer runs through the plant until the connection has passed the applicator head. Thereafter, the second spacer is separated in a region between the connection and the applicator head.

  • Patent number: 9103162
    Abstract: A device for applying an elastoplastic spacer tape as a spacer during the production of insulating glass panes has at least two supply reels for spacer tapes, several driven tape guide rollers, and a movable application head for the selected spacer tape, with whose assistance the spacer tape is pressed onto a glass pane. For coating one or the other spacer tape, a coating station with two coating nozzles is provided, from which adhesive glue is sprayed on the lateral surfaces of the selected spacer tape. The spacer tape that is unneeded in each case is stopped in the application head in such a way that one or the other of the spacer tapes as desired, depending on which spacer tape is required for the production of a special insulating glass pane, is applied to the glass pane. Thus, the laborious threading and unthreading of spacer tapes is not necessary.

  • Patent number: 8758532
    Abstract: An device for simultaneous application of elastoplastic spacer tapes to two glass panes with identical outline shape and identical dimensions has two application heads (107) that can be adjusted essentially vertically up and down on linear axles (105). The application heads (107) are moved synchronously, likewise the two glass panes by the holding devices that are assigned to them and that move the glass panes in a direction that is perpendicular to the direction of motion of the application heads (107). Thus, it is sufficient to measure a single glass pane of a triple insulating glass element, and both application panes of the insulating glass element can be covered at the same time with spacer tapes, so that time is saved, and the two application panes can be assembled with the cover pane in a shorter time interval into an insulating glass element with three panes.
