    • In application of a foamed hot melt adhesive, a mixing ratio of foam can be selectably and quickly set, and also application of a foamed hot melt adhesive and that of a solid hot melt adhesive can be selectively performed by a single application device. A first gear pump and a second gear pump are driven by drive mechanisms independent from each other. The pressure of a liquid being sent by the pressure in the second compression process is detected, and this causes the speed of the first gear pump and the second gear pump to be sequence-controlled to automatically control the amount of mixing of gas. A gas suction opening is provided between the first gear pump and the second gear pump, and a mixer is provided between the gas suction opening and the second gear pump. The end of a return circuit is set on the downstream side of the first gear pump to prevent foam from returning to the tank side. A restriction valve is installed in a gun to produce a single bubble. The ratio of discharges between the first gear pump and the second gear pump is automatically controlled and set at a value greater than 1/1, enabling solid hot melt adhesive application and foamed hot melt application to be selectively performed.
    • 在发泡热熔粘合剂的应用中,泡沫的混合比例可以选择地且快速地进行设定,并且也可以通过单个涂布装置选择性地进行发泡热熔粘合剂和固体热熔粘合剂的涂布。 第一齿轮泵和第二齿轮泵由彼此独立的驱动机构驱动。 检测在第二压缩过程中由压力传送的液体的压力,这导致第一齿轮泵和第二齿轮泵的速度被顺序控制以自动控制气体的混合量。 在第一齿轮泵和第二齿轮泵之间设有气体吸入口,在气体吸入口和第二齿轮泵之间设有混合器。 返回回路的末端设置在第一齿轮泵的下游侧,以防止泡沫返回到油箱侧。 一个限制阀安装在枪中以产生单个气泡。 自动控制第一齿轮泵和第二齿轮泵之间的排放比例,并将其设定为大于1/1的值,从而能够选择性地进行固体热熔粘合剂施加和发泡热熔胶涂敷。

    • A truncated cone which causes pressurized air flow from plural pressurized air holes to rotate and flow down along the circumferential surface of the truncated cone is provided connectedly at the underside of a nozzle base. A pair of (right and left) downward slanting surfaces which are recessed in V-shape (in side view) are formed in such a fashion that they oppose to each other and slant upward and toward the center. A nozzle projection whose underside is a non-circular shape having a minor axis in the direction where the lower ends of the downward slanting surfaces exist and a major axis in the direction where the lower ends of the downward slanting surfaces do not exist, is provided connectedly at the underside of the truncated cone. In the second invention of the present application, adhesive exposing surface is formed at a part of the downward slanting surface. In the third invention of the present application, the major axis direction of the underside of the nozzle projection is made changeable so as to make the major axis direction of the major axis oval shape (in cross section) selectable.
