    • Methods and apparatus for low-cost manufacture of reclosable packages having slider-operated zippers. One method of manufacture comprising the following steps: (a) joining film material to a back side of a first flangeless zipper strip having a first closure profile on its front side; (b) joining film material to a back side of a second flangeless zipper strip having a second closure profile on its front side, the first and second closure profiles of the first and second zipper strips being interlockable to form a string zipper assembly; and (c) loading a slider comprising a plow onto an open section of the string zipper assembly with the plow being inserted between the first and second flangeless zipper strips. Respective portions of the first and second portions of film are respectively disposed between the slider and the string zipper assembly when the slider is loaded. This method further comprises the step of trimming a marginal portion of the film material that extends beyond the portion of film material joined to the back side of either of the first flangeless zipper strip.
    • 用于低成本制造具有滑动操作的拉链的可再封闭包装的方法和装置。 一种制造方法包括以下步骤:(a)将薄膜材料连接到其前侧具有第一闭合轮廓的第一无凸缘拉链带的背面; (b)将薄膜材料连接到其前侧具有第二闭合轮廓的第二无凸缘拉链带的后侧,所述第一和第二拉链带的第一和第二闭合轮廓可互锁以形成拉链组件; 以及(c)将包括犁的滑块装载到弦拉链组件的开口部分上,犁插入第一和第二无凸缘拉链条之间。 当滑块被加载时,胶片的第一和第二部分的各个部分分别设置在滑块和弦拉链组件之间。 该方法还包括修整薄膜材料的边缘部分的步骤,该边缘部分延伸超过连接到第一无凸缘拉链带中的任一个的背面的薄膜材料的部分。
