    • A slide fastener having a separating end stop formed of male and female components secured to a pair of tapes carrying interengaging elements along the inner edges thereof and upper and lower opposed sliders movable to control engagement of the interengaging elements, the male and female components having outer surfaces contoured to contact side walls of the lower slider as the lower slider is moved along the components to pivot the components toward each other and stress the tapes. The stress on the tapes causes the outer surfaces of the components to bear against the side walls of the lower slider and move the lower slider along the components to a position covering the junctions of the components and the interengaging elements.
    • 一种拉链,其具有分离端部止动件,该分离端部止动件由固定到一对沿其内边缘承载相互接合元件的一对带状物的阳和阴部件形成,上下相对的滑块可移动以控制相互接合元件的接合,所述阳部件和阴部件具有外部 当下部滑块沿着部件移动以将部件朝向彼此枢转并且对带施加压力时,轮廓形成为接触下滑动件的侧壁的表面。 带子上的应力导致部件的外表面抵靠下滑动件的侧壁并且沿着部件移动下滑块到覆盖部件和相互接合元件的接合处的位置。

    • A slide fastener having terminal fastener elements reduced in size relative to the remaining fastener elements and two stop members adjacent the terminal fastener elements, each stop member being formed from a mass of fusible material fused onto a slide fastener tape, the reduced terminal fastener elements accommodating the diamond of a slider when the slider engages the stop members to prevent splay of the slide fastener tapes. A method of forming the above described slide fastener including supporting a slide fastener chain to expose the terminal fastener elements, reducing the size of the terminal fastener elements, and fusing a mass of fusible material onto each slide fastener tape to form the stop members. Apparatus for forming the above described slide fastener including a support block having parallel channels for receiving separate slide fastener tapes, a forming anvil having a pair of spaced legs movable in the channels to capture the terminal fastener elements in cavities therein, a source for supplying ultrasonic energy to the forming anvil to reduce the size of the terminal fastener elements, a forming block supporting the separated slide fastener tapes adjacent cavities defined therein by another forming anvil, a forming member engaging the forming block to move the forming block relative to the other forming anvil and shear blanks of fusible material in the cavities, and a source for supplying ultrasonic energy to the forming member to fuse the blanks onto the slide fastener tapes to form separate stop members.
    • 一种拉链,其具有相对于剩余的紧固件元件减小尺寸的拉链元件和与终端紧固件元件相邻的两个止动件,每个止动件由融合到拉链带上的大量可熔材料形成, 当滑块与止动构件接合以防止拉链带的张开时滑块的金刚石。 一种形成上述拉链的方法,包括支撑拉链链以露出终端紧固件元件,减小端子紧固元件的尺寸,并将大量可熔材料熔合到每个拉链带上以形成止动件。 用于形成上述拉链的装置包括具有平行通道的支撑块,用于容纳单独的拉链带;成形砧座,其具有可在通道中移动的一对间隔的支柱,以将端子紧固元件捕获在其中的空腔中; 形成砧座的能量以减小终端紧固件元件的尺寸;成形块,其通过另一个成形砧支撑分隔的拉链带与其中限定的隔离的拉链带;成形件,与成形块接合,以使成形块相对于另一个成形 在空腔中的可熔材料的砧座和剪切坯料以及用于向成形构件供应超声能量以将坯料熔合到拉链带上以形成分开的止动构件的源。
