As a result, after the cup panel has become put inside the groove Identification of your sealing strip 5, the closing lip I2 is brought on to return to its typical sealing placement proven in Stats 2 and 1, either by withdrawing the device I8 of Figure 4 or admitting oxygen to interrupt the vacuum inside the passageway I3 of Figure 4, or by discharging compressed air flow in the passageway I3 of Body 4a. Your window installing in general then shows up as displayed in Body 8.
During installment, the open comes to an end of the passageway I3 inside the sealing strip 5 could be sealed and produced air-tight by cementing or vulcanizing the exact opposite ends of your securing strip 5 where they abut one another, as demonstrated at 5a in Physique 8. It has been specifically found feasible to close the passageway I3 sufliciently for that purpose of the present invention of panel packing only by decreasing the sealing strip to some length above its essential span, as an example about 1 quarter in . over needed. When this extremely extended securing strip 5 needs in the panel starting, the ends 5a are compressed collectively from the resilience of your securing strip 5, sealing the joints between the two.
Such as the invention of panel packing displayed in Stats 5 to ’7 comprehensive, the closing strip 30 is formed by extruding rubber or some other suitable material towards the desired form. so as’to supply a body section 3| developing a bottom part wall 32 given a main slot 33 for getting a rib 34 on the framework associate or maybe the like as at 35. The structure fellow member 35 might make up the route percentage of a window opening up and is provided with downwardly increasing flanges 36 as displayed in Physique 5.
The body portion 3| of the sealing strip is provided with some windows pane acquiring grooves 31 established in parallel spread out connection and said grooves have inwardly aimed wall surfaces providing closing lip servings 38 similar to the securing lip servings II and I2 of the panel packaging devices demonstrated in Figures 1 to 4a inclusive. Along side it wall space 39 of the closing strip are arcuately curved in go across section and the entire body portion 3| of your securing strip is provided with longitudinally extending openings or passageways 40 experiencing opposed inside curved wall space 4. The inside curved wall space 42 are designed to coincide together with the aspect walls 39 to be able to develop an arcuately curved wall surface portion 43 as displayed plainly in Body
