  • the glue applying apparatuses of the four units are activated for applying glue to the fingers just cut in the ends of the frame components. This is done by activating a hydraulic cylinder to raise glue applying implements which are submerged in glue containers so as to pass the end surfaces of the frame components to which the glue is to be applied.
  • the table 46 islowered by releasing of the pressure in the hydraulic cylinder 45 until the frame has come to rest on a conveyor comprising two endless belts 40 and 41 supported by rollers attached to the respective units in such a way as to accommodate mutual displacement of the units by rearranging the machine for production of frames of another dimension.

  • they are driven by the same motor and their respective driving rollers being interconnected by a telescopic shaft 42.
  • these strips have the important purpose of eliminating small inaccuracies between the glass panes and the frame components and especially by their tapering profile to ensure a proper insertion in the grooves of the frame components by the automatic joining of the same as otherwise the pane inevitably would be crushed causing wasteful interruptions of the continuous manufacturing process.
  • FIG. 9-13 The sealing strips adapted for this purpose are shown in FIG. 9-13.
  • FIG. 9 shows a comer of a windowpane 47 on the edges of which are mounted sealing strips 72 of resilient material. The strips are cut to lengths to form a mitre joint at the corners but with a narrow gap 73 between adjacent strips.

  • the sealing strip 72 placed on the edge of the pane has a generally U-shaped cross section with two legs 76 and 77 and a bottom 75.
  • the bottom 75 will show a somewhat arcuate profile so that it will bend away from the edge of the pane.
  • the legs 76 and 77 have at their free ends inturning lips 78 and 79, resp. which will cause the legs also to diverge from the surface of the pane.
  • the legs 76 and 77 further have at their ends joining the bottom 75 extensions which at least with the outer surfaces 80 and 81, resp. are tapering outwards against the median plane of the pane. This will greatly facilitate and ensure proper introduction of the pane in the groove 84 in the frame member 15 by the assembly of the frame in the machine. Further these extensions will in the assembled window by being bent inwardly together with deformation of the bottom 75 which will be straightened out as shown in FIG. 11 ensure that the pane in the assembled window will be elastically clamped to a certain extent and compensate for small'inaccuracies in the dimensions of the pane and the frame members.
  • At least one side of the pane and preferably both sides of the pane are covered with a thin sheet or film 82 preferably of plastic.
  • This covering which for the sake of clearness in the drawings is shown in some distance from the pane will in practice lie adjacent the surfaces of the pane and may be of a semiadhering type which will facilitate applying of the covering to the pane in a highly mechanized manufacturing process.
  • the covering 82 is placed inside the sealing strips 72 but it may also be placed around the sealing strips and thereby assist in keeping the sealing strips on place during the handling of the glass panes in the machine.
  • the covering When the windows are going to be taken into use the covering may easily be removed and discarded by cutting it along the edges of the sealing strips or frame members.
  • the part of the covering which is hidden inside the grooves84 is harmless and may be left in place.
  • the covering 82 also substantially will facilitate subsequent treatment of the windows such as painting or staining as well as protecting the pane during transportation and handling.

By this embodiment only the one. leg 76 of the U-formed strip is extended over the bottom 75 which'only diverges from the pane 47 at its one end. The elastic'deformation of the sealing strip by inserting in the groove of the frame member 15 will appear from FIG. 13.
