    • Methods and apparatus for stretching a plastic tape before the tape is joined in proper registration to a web of material in a machine. The apparatus comprises: means for advancing a leading portion of a flexible tape along a tape pathway; a guide that guides a lagging portion of the tape; a brake mounted to the guide and activatable to clamp a portion of the lagging portion of the tape at a first location; a sensor mounted to the guide and arranged to output a characteristic signal whenever the passage of a boundary of a structural feature of a particular type, repeatedly formed on or attached to the tape, is detected at a second location upstream of the first location; and a controller for causing the leading portion of the tape to be advanced a predetermined distance at regular spaced intervals of time and for causing the brake to clamp the lagging portion in response to the output of the characteristic signal by the sensor. The second location is selected such that the brake clamps the lagging portion while the leading portion is still being advanced, whereby a portion of the tape disposed downstream from the brake is stretched.
    • 在将胶带与机器中的材料卷正确对准之前,将胶带拉伸的方法和装置。 该装置包括:用于沿着带通道推进柔性带的引导部分的装置; 引导磁带的滞后部分的引导件; 制动器,其安装到所述引导件并且可激活以在所述第一位置处夹持所述带的所述滞后部分的一部分; 传感器,其安装到所述引导件,并且每当在所述第一位置的上游的第二位置处检测到重复地形成在所述带上或附着到所述带上的特定类型的结构特征的边界的通过时,输出特征信号; 以及控制器,用于使带的前端部分以规则间隔的间隔前进预定距离,并且用于使制动器响应于传感器的特征信号的输出而夹紧滞后部分。 选择第二位置,使得制动器在引导部分仍在前进时夹持滞后部分,由此布置在制动器下游的一部分带被拉伸。

    • A method of manufacture comprising the following steps: (a) continuously advancing a web of bag making material at a first rate; (b) continuously joining portions of a downstream portion of a fastener tape to respective portions of the continuously advancing web of bag making material; (c) intermittently advancing an upstream portion of the fastener tape while the downstream portion is advancing continuously, the halt at the end of each intermittent advance being the start of the next work cycle, the upstream portion of the fastener tape being stationary during a respective dwell time of each work cycle and advancing during the remainder of each work cycle at a second rate faster than the first rate; (d) accumulating a portion of the fastener tape disposed between the upstream and downstream portions to compensate for the difference in the first and second rates during the aforementioned remainder of each work cycle; and (e) inserting a respective slider onto the upstream portion of the fastener tape during each dwell time.
    • 一种制造方法,包括以下步骤:(a)以第一速率连续推进制袋材料的幅材; (b)将拉链带的下游部分连续地连接到制袋材料的连续前进的幅材的相应部分上; (c)在下游部分连续前进的同时间歇地推进拉链带的上游部分,在每个间歇前进结束时的停止是下一个工作循环的开始,拉链带的上游部分在相应的 每个工作周期的停留时间和在每个工作周期的剩余时间内以比第一速率快的第二速率进行; (d)累积设置在上游和下游部分之间的拉链带的一部分,以补偿在每个工作周期的上述剩余时间期间第一和第二速率的差异; 和(e)在每个停留时间期间将相应的滑块插入拉链带的上游部分。
