    • A method and an apparatus for continuously filling grooves in metal sash bars with heat insulating synthetic resin are disclosed. The method comprises the steps of closing the opposite ends of the groove of each of the metal sash bars by end caps each having an end wall with a thinned top edge; continuously moving the metal sash bars through a path below an injection device with the grooves facing upwardly and with at least the top edges of the end caps of one preceding sash bar and the succeeding sash bar in close contact with each other on the upstream of the injection device; and continuously injecting a solution of the heat insulating synthetic resin from the injecting device into the grooves of the sash bars at a constant injecting rate while continuously moving the sash bars.The apparatus comprises: a means for attaching end caps to opposite ends of the groove of each of the metal sash bars to close the opposite ends, the cap each having an end wall with a thinned top edge; and injection device positioned downstream of the cap attaching means for continuously injecting a solution of the heat insulating synthetic resin; a feed device positioned near the injection device for continuously moving the sash bars along a path below the injection device with the grooves facing upwardly; and a rapid feed device positioned upstream of the feed device for moving a succeeding sash bar toward the preceding sash bar which is being injected with the solution of heat insulating synthetic resin at a higher rate than that by the feed device so that at least the top edges of the end caps of the preceding sash bar and the succeeding sash bar are in close contact with each other.
    • 公开了一种用绝热合成树脂连续填充金属窗框中的槽的方法和装置。 该方法包括以下步骤:通过端盖封闭每个金属窗框的槽的相对端部,每个端盖具有具有变薄的顶部边缘的端壁; 连续移动金属窗框通过注射装置下方的路径,其中凹槽面向上,并且至少前一个窗格条的端盖的顶部边缘和后续的窗框在彼此的上游彼此紧密接触 注射装置; 并且连续地将所述隔热合成树脂的溶液从所述注射装置以恒定的喷射速度连续地喷射到所述窗条的槽中。 该装置包括:用于将端盖附接到每个金属窗框的槽的相对端部以闭合相对端的装置,每个顶盖具有带有变薄的顶部边缘的端壁; 以及位于所述盖安装装置下游的注射装置,用于连续注射所述绝热合成树脂的溶液; 位于注射装置附近的进给装置,用于沿着注射装置下方的路径连续地移动窗框,其中槽面向上; 以及位于进给装置上游的快速进给装置,用于将后续的窗框朝向先前的边框条进行移动,所述后门条以比绝缘合成树脂的溶液更高的速度注入绝缘合成树脂溶液,使得至少顶部 先前的格栅条的端盖和后续的窗框的边缘彼此紧密接触。
