    • The disclosed web splicing apparatus and method provide for the in-registry lap splicing of a new web, that has a spaced, regularly repeating pattern thereon to an expiring web that has an identical, spaced, regularly repeating pattern thereon and that is moving under tension and at a relatively high speed along a predetermined path of travel. The leading end =of the new web is prepared for a splice so that a pattern thereon is aligned with a first pre-selected point. During a splice, a portion of the expiring web is substantially stopped and then moved at a relatively slow speed past a sensor that is positioned at a second pre-selected point downstream from the first pre-selected point and that senses the passage of the next pattern on the slowly moving expiring web. Upon the sensing of the passage of the next pattern, the leading end of the new web is secured to a part of the portion of the expiring web upstream from the second pre-selected point, and the portion of the expiring web is cut upstream from the secured part of the expiring web. Thereafter the joined webs are permitted to run along the path of travel at the relatively high speed.
    • 所公开的网状拼接装置和方法提供了一种新的网状物的注册中的膝部拼接,其在其上具有间隔开的规则重复的图案,其上具有在其上具有相同,间隔开的规则重复图案并且在张力下移动的到期纤维网 并且沿着预定的行进路径以相对高的速度。 准备新网的前端=用于拼接,使得其上的图案与第一预选点对准。 在接合期间,一段期满的幅材基本停止,然后以比较慢的速度移动经过位于第一预选点下游的第二预选点的传感器,并且感测下一个 在缓慢移动的过期网络上的图案。 在感测到下一个图案的通过时,新纸幅的前端被固定到从第二预选点上游的过期纸幅的一部分的一部分,并且到期纸幅的部分被从 过期网络的安全部分。 此后,接合的网被允许以相对较高的速度沿着行进路径行进。
